    Full Text Available Abstract - The present article reports the findings of an investigation into the metaphorical expressions adopted by English-language magazines to describe the latest economic/financial crisis. The corpus used for the investigation was about 100,000 words large, with texts taken from The Economist and from The International Economy. All the articles selected from these two magazines were published between Fall 2008 and Winter 2012. The main aim of the inquiry was to offer a more detailed and comprehensive classification of economic-crisis-metaphors than those proposed in previous research. In this respect, a total number of forty different types of such metaphors was identified. Alongside the theoretical classification, a quantitative analysis of the data was also carried out in order to find out which kinds of metaphorical expression are used most frequently. Results suggest that the economic/financial crisis is predominantly conceptualized in terms of something negative about a human being, about an object, and about a motion. In particular, viewing a state of economic/financial crisis as a damaged or destroyed object appears to be the most widely adopted metaphor. Results also suggest that different economics magazines can vary significantly in the amount of metaphorical language used.Keywords: metaphor, economic crisis, semantics, pragmatics, journalistic styles.  Sommario – Questo articolo riporta i risultati di una ricerca sulle metafore adottate da riviste in lingua inglese per descrivere la recente crisi economica e finanziaria. Il corpus utilizzato per l’indagine è stato di circa 100.000 parole, con testi reperiti dal The Economist e dal The International Economy. Tutti gli articoli selezionati da queste due riviste sono stati pubblicati tra l’autunno 2008 e l’inverno 2012. Lo scopo principale dell’indagine è stato quello di fornire una classificazione delle metafore della crisi economica più dettagliata ed esauriente di

    2013-08-01

    The economic evaluation of telemental health (TMH) is necessary to inform ways to decrease the cost of delivering care, to improve access to care, and to make decisions about the allocation of resources. Previous reviews of telehealth economic analysis studies have concluded that there are significant methodological deficiencies and inconsistencies that limit the ability to make generalized conclusions about the costs and benefits of telehealth programs. Published economic evaluations specific to TMH are also limited. There are unique factors that influence costs in TMH that are necessary for those who are planning and evaluating economic analyses to consider. The purpose of this review is to summarize the main problems and limitations of published economic analyses, to discuss considerations specific to TMH, and to inform and encourage the economic evaluation of TMH in both the public and private sectors. The topics presented here include perspective of costs, direct and indirect costs, and technology, as well as research methodology considerations. The integration of economic analyses into effectiveness trials, the standardization of outcome measurement, and the development of TMH economic evaluation guidelines are recommended.

    To investigate whether the incorporation of rubella vaccine into immunization programmes in developing countries is economically justified. A MEDLINE search was conducted for articles published between 1970 and 2000 that dealt with economic analyses of rubella and rubella-containing vaccines. The Eastern Mediterranean, South-East Asia, and Africa regional Index Medicus databases and the LILACS database for Latin America and the Caribbean were also searched. For developed countries, five cost- benefit analyses of rubella vaccine and five of measles-mumps-rubella vaccine as well as two cost-effectiveness analyses were found. For developing countries, five cost analyses and five cost-benefit analyses were found. All the cost-benefit analyses had a benefit:cost ratio greater than 1 and the cost-effectiveness studies indicated that rubella immunization was a cost-effective means of reducing the impact of congenital rubella syndrome. However, the methodologies were not standardized. The data support the inclusion of rubella vaccine in the immunization programmes of both developing and developed countries and indicate economic benefits comparable to those associated with hepatitis B vaccine and Haemophilus influenzae type b vaccine. More studies should be carried out on costs for care and immunization using standardized methodologies and locally obtained information.

    To describe and evaluate economic analyses or economic evaluations in pediatric urologic literature, including study types such as cost-effectiveness analysis, which are increasingly common in the medical literature. We performed a systematic literature review of the MEDLINE, EMBASE, and Cochrane databases (1990-2011) to identify economic analyses of pediatric urologic topics. Studies were evaluated using published quality metrics. We examined the analysis type, data sources, perspective, methodology, sensitivity analyses, and the reporting of methods, results, limitations, and conclusions. We identified 2945 nonduplicated studies, 60 of which met inclusion criteria. Economic analyses of pediatric urologic topics increased in number during the study period, from 1 study (2%) in 1990 to 7 (12%) in 2010 (P pediatric urologic literature, there is a need for standardization in methods and reporting. Future investigations should attempt to follow standardized reporting guidelines and should pay particular attention to reporting of methods and results, including a comprehensive discussion of limitations.

    via journal webpages for further assessment. Thirty-two papers were finally included in a thorough data extraction procedure, including those identified by a “gray literature search” utilizing the Google search engine and cross-reference searches. Results regarding content of the studies showed that malnutrition was the underlying clinical condition in most cases (32%. In addition, gastrointestinal disorders (eg, surgery, cancer were often analyzed. In terms of settings, 56% of papers covered inpatients, whereas 14 papers (44% captured outpatients, including patients in community centers. Interestingly, in comparison with the papers identified overall, very few health economic models were found. Most of the articles were modeling analyses and economic trials in different design settings. Overall, only eight health economic models were published and were validated applying the Drummond checklist. In summary, most of the models included were carried out to quite a high standard, although some areas were identified for further improvement. Of the two systematic health economic reviews identified, one achieved the highest quality score when applying the AMSTAR checklist. Conclusion: The reasons for finding only a few modeling studies but quite a large number of clinical trials with health economic endpoints, might be different. Until recently, health economics has not been required for reimbursement or coverage decisions concerning medical nutrition interventions. Further, there might be specifics of medical nutrition which might not allow easy modeling and consequently explain the limited uptake so far. The health economic data on medical nutrition generated and published is quite ample. However, it has been primarily based on database analysis and clinical studies. Only a few modeling analyses have been carried out, indicating a need for further research to understand the specifics of medical nutrition and their applicability for health economic modeling.

    The first step in teaching-to-understand economics is not teaching "the rules," but working with fundamental economic models from the outset. Many of the concepts in economics are illustrated through models. Students must: (1) be able to draw these models; (2) understand the assumptions of the models; and (3) use the models for analysis.…

    2016-11-01

    In the course of the chronic skin disease psoriasis, where a variety of treatment interventions is available, a strong growth of health economic studies comparing treatment costs and benefits can be noticed. The objective was to identify health economic evaluations of psoriasis treatments that have been published to date. Of particular interest were the mostly used analysis and outcome parameters, the compared treatments, and the question, if available health economic studies may be used to perform a meta-analysis of qualitative findings. A systematic literature search using PubMed Medline, Ovid Medline, and Cochrane Library was performed for articles, published and available until mid of January 2016. Among the key words were the terms "psoriasis" and "cost-effectiveness". The search resulted in 318 articles without duplicates. Thereof 60 health economic analyses in psoriasis management were identified. Most of these are cost-effectiveness evaluations (45). The clinical parameter PASI (Psoriasis Area Severity Index) is the most often used cost-effectiveness outcome (33) followed by the Dermatology Life Quality Index (DLQI) (6). In case of cost-utility analyses, QALYs (quality-adjusted life-years) were mostly generated with the help of EuroQol five dimensions questionnaire (EQ-5D) (12), which was partly based on PASI and DLQI values. The majority of health economic studies is focusing on the direct medical and non-medical costs without consideration of productivity losses. Almost 70 % of 60 publications were conducted in Europe. Overall, most considered systemic treatments were the biological agents etanercept (36), adalimumab (27), and infliximab (26) followed by ustekinumab (17) and phototherapy (incl. UV-B, PUVA/psoralen combined with UV-A) (14). Comparisons including only topical treatments mostly focused on vitamin D treatment (14), corticosteroids (13), and coal tar products (6) followed by dithranol (5) and tazarotene (4). Given the setting, compared

    The availability of hard clinical end-point data, such as that on cardiovascular (CV) events among patients with type 2 diabetes mellitus, is increasing, and as a result there is growing interest in using hard end-point data of this type in economic analyses. This study investigated published approaches for modeling hard end-points from clinical trials and evaluated their applicability in health economic models with different disease features. A review of cost-effectiveness models of interventions in clinically significant therapeutic areas (CV diseases, cancer, and chronic lower respiratory diseases) was conducted in PubMed and Embase using a defined search strategy. Only studies integrating hard end-point data from randomized clinical trials were considered. For each study included, clinical input characteristics and modeling approach were summarized and evaluated. A total of 33 articles (23 CV, eight cancer, two respiratory) were accepted for detailed analysis. Decision trees, Markov models, discrete event simulations, and hybrids were used. Event rates were incorporated either as constant rates, time-dependent risks, or risk equations based on patient characteristics. Risks dependent on time and/or patient characteristics were used where major event rates were >1%/year in models with fewer health states (rates. The detailed modeling information and terminology varied, sometimes requiring interpretation. Key considerations for cost-effectiveness models incorporating hard end-point data include the frequency and characteristics of the relevant clinical events and how the trial data is reported. When event risk is low, simplification of both the model structure and event rate modeling is recommended. When event risk is common, such as in high risk populations, more detailed modeling approaches, including individual simulations or explicitly time-dependent event rates, are more appropriate to accurately reflect the trial data.

    1982-09-01

    Government agencies that offer financial incentives to stimulate the commercialization of synfuel and unconventional gas technologies usually require an analysis of environmental impacts resulting from proposed projects. This report reviews potentially significant environmental issues associated with a selection of these technologies and presents guidance for developing information and preparing analyses to address these issues. The technologies considered are western oil shale, tar sand, coal liquefaction and gasification, peat, unconventional gas (western tight gas sands, eastern Devonian gas shales, methane from coal seams, and methane from geopressured aquifers), and fuel ethanol. Potentially significant issues are discussed under the general categories of land use, air quality, water use, water quality, biota, solid waste disposal, socioeconomics, and health and safety. The guidance provided in this report can be applied to preparation and/or review of proposals, environmental reports, environmental assessments, environmental impact statements, and other types of environmental analyses. The amount of detail required for any issue discussed must, by necessity, be determined on a case-by-case basis.

    The progress to date in the development and analysis of computer simulations of solar-powered desiccant cooling using an axial-flow disc-type dehumidifier wheel, solar-powered space heating, and electrically driven, standard vapor-compression air-conditioning systems for residential use is documented. Computer simulations for both solar and conventional heating and cooling systems were performed for 12-month heating and cooling seasons. Annual thermal performance and the resulting life cycle costs for both types of systems were analyzed and compared. The heating/cooling season simulations were run for five U.S. cities representing a wide range of climatic conditions and insolation. With the informaion resulting from these simulations, the optimum air-conditioning system was chosen to maximize the conservation of fossil fuels and minimize operating costs. Because of the increasing use of residential air conditioning employing electrically driven vapor-compression coolers, the five locations were studied to determine if it would be beneficial (in terms of both economics and fossil fuel displacement) to displace fossil-fuel-powered vapor-compression coolers and natural gas space heaters with solar-powered heating and desiccant cooling systems.

    Arion, Douglas

    2012-02-01

    For many years it has been recognized that many physicists are ``hidden'' -- deep in the industrial world or holding positions not named ``physicist.'' In parallel with this phenomenon is the recognition that many new and innovative product ideas are, in fact, generated by physicists. There are many more ideas that could be brought to market to the benefit of both society and the inventor, but physicists don't often see themselves as the innovators and inventors that they actually are. A number of education programs have arisen to try to address this issue and to engender a greater entrepreneurial spirit in the scientific community. The ScienceWorks program at Carthage College was one of the first to do so, and has for nearly twenty years prepared undergraduate science majors to understand and practice innovation and value creation. Other programs, such as professional masters degrees, also serve to bridge the technical and business universes. As it is no doubt easier to teach a scientist the world of business than it is to teach a businessperson the world of physics, providing educational experiences in innovation and commercialization to physics students can have tremendous economic impact, and will also better prepare them for whatever career direction they may ultimately pursue, even if it is the traditional tenure-track university position. This talk will discuss education programs that have been effective at preparing physics students for the professional work environment, and some of the positive outcomes that have resulted. Also discussed will be the variety of opportunities and resources that exist for faculty and students to develop the skills, knowledge and abilities to recognize and successfully commercialize innovations.

  1. Economic Impact Analyses of Interdisciplinary Multi-hazard Scenarios: ShakeOut and ARkStorm

    2011-12-01

    U. S. Geological Survey (USGS) scientists are using an interdisciplinary strategy to develop and analyze multi-hazard scenarios to help communities enhance resilience to natural hazard disasters. Two such scenarios are the southern California ShakeOut earthquake and the California ARkStorm winter storm. Both scenarios are multi-hazard: Shakeout ground motions trigger landslides and liquefaction and ARkStorm involves wind, flood, landslide, and coastal hazards. A collaborative scenario-process engages partners and stakeholders throughout the development and use of the scenarios, In doing so, community resilience is enhanced by educating communities about hazards and hazard interdependencies, building networks from scientists to decision makers, exercising emergency management strategies, identifying emergency management issues, and motivating solutions prior to an event. In addition, interdisciplinary scenarios stimulate research on the various steps of analysis (e.g., natural hazard processes, physical damages, societal consequences, and policy connections). In particular, USGS scientists have collaborated with economists to advance methods to estimate the economic impacts (business interruption losses) of disasters. Our economic impact analyses evolved from the economic module in the Federal Emergency Management Agency's loss-estimation tool, HAZUS-MH, to a more encompassing input-output analysis for ShakeOut, to a more sophisticated Computable General Equilibrium model for ARkStorm. The analyses depend on physical damage and restoration time estimates from engineers and geographic analyses of economic assets in hazard zones. Economic resilience strategies are incorporated to represent resourcefulness and ingenuity that avoids potential losses during and after an event. Such strategies operate at three levels of the economy: micro (e.g., ability to catch up on lost production time), meso (e.g., coordination within a sector to share resources), and macro (e

    Retrospective database analyses pose a series of methodological challenges, some of which are unique to their data sources, particularly in countries outside the US. This study aimed to qualitatively review the methodological challenges of using non-US databases to conduct retrospective economic and outcomes research studies. We conducted a MEDLINE search to obtain a sample of literature published after the year 2000 on retrospective analyses using non-US databases. We reviewed all relevant components of the selected articles in accordance with the checklist proposed for retrospective database studies by the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Task Force and identified issues found in the data sources, methods, study designs, statistics and sources of possible threats to internal and external validity. We found a wide variation in the quality of studies in terms of outcome definitions, patient selection criteria, data collection methods, sample sizes, risk adjustment methods, potential measurement errors and external validity of the studies. Few economic studies included information on indirect cost components because of a lack of relevant data. The quality of non-US retrospective database analyses varied. Future such analyses may be improved if researchers implement the checklist developed by the ISPOR Task Force on Retrospective Database Studies.

    Economists are increasingly using weather data and climate model output in analyses of the economic impacts of climate change. This article introduces a set of weather data sets and climate models that are frequently used, discusses the most common mistakes economists make in using these products, and identifies ways to avoid these pitfalls. We first provide an introduction to weather data, including a summary of the types of datasets available, and then discuss five common pitfalls that empirical researchers should be aware of when using historical weather data as explanatory variables in econometric applications. We then provide a brief overview of climate models and discuss two common and significant errors often made by economists when climate model output is used to simulate the future impacts of climate change on an economic outcome of interest.

    The impact of natural hazards on the economic system can be observed in many different regions all over the world. Once the local economic structure is hit by an event direct costs instantly occur. However, the disturbance on a local level (e.g. parts of city or industries along a river bank) might also cause monetary damages in other, indirectly affected sectors. If the impact of an event is strong, these damages are likely to cascade and spread even on an international scale (e.g. the eruption of Eyjafjallajökull and its impact on the automotive sector in Europe). In order to determine these special impacts, one has to gain insights into the directly hit economic structure before being able to calculate these side effects. Especially, regarding the development of a model used for near real-time forensic disaster analyses any simulation needs to be based on data that is rapidly available or easily to be computed. Therefore, we investigated commonly used or recently discussed methodologies for regionalizing economic data. Surprisingly, even for German federal states there is no official input-output data available that can be used, although it might provide detailed figures concerning economic interrelations between different industry sectors. In the case of highly developed countries, such as Germany, we focus on models for regionalizing nationwide input-output table which is usually available at the national statistical offices. However, when it comes to developing countries (e.g. South-East Asia) the data quality and availability is usually much poorer. In this case, other sources need to be found for the proper assessment of regional economic performance. We developed an indicator-based model that can fill this gap because of its flexibility regarding the level of aggregation and the composability of different input parameters. Our poster presentation brings up a literature review and a summary on potential models that seem to be useful for this specific task

A major element which contributes to regional inequalities is the level of competitiveness. This element has been the subject of numerous studies over the past years, even though more attention was given to the national level and less to the regional one. Moreover, the purpose of these regional analyses is the correlation of territorial objectives and problems with possible sources of financing, seeing to ensure optimal combinations between regional demand and supply, the optimal distribution of the income and of the results obtained, regional competitiveness, the location of clusters, etc.

    Full Text Available The refrigeration processes have been widely applied for especially in cold storages. In these plants, the systems working with compressed vapour cooling cycles have been used as a classical method. In general, electrical energy is used for compressing in these processes. Although, mainly the electricity itself has no pollution effect on the environment, the fossil fuels that are widely used to produce electricity in the most of the world, affect the nature terribly. In short, these refrigeration plants, because of the source of the electricity pollute the nature indirectly. However, for compression an ejector refrigeration system requires one of the important renewable energy sources with negligible pollution impact on the environment, namely solar energy from a thermal source. Thermodynamical, environmental and economical aspects of the ejector refrigeration system working with solar energy was investigated in this study. As a pilot case, apple cold storage plants widely used in ISPARTA city, which 1/5 th of apple production of TURKEY has been provided from, was chosen. Enviromental and economical advantages of solar ejector refrigeration system application for cold storage dictated by thermodynamic, economic and enviromental analyses in this research.

    Technoeconomic analyses have been conducted on two processes to produce hydrogen from biomass: indirectly-heated gasification of biomass followed by steam reforming of the syngas, and biomass pyrolysis followed by steam reforming of the pyrolysis oil. The analysis of the gasification-based process was highly detailed, including a process flowsheet, material and energy balances calculated with a process simulation program, equipment cost estimation, and the determination of the necessary selling price of hydrogen. The pyrolysis-based process analysis was of a less detailed nature, as all necessary experimental data have not been obtained; this analysis is a follow-up to the preliminary economic analysis presented at the 1994 Hydrogen Program Review. A coproduct option in which pyrolysis oil is used to produce hydrogen and a commercial adhesive was also studied for economic viability. Based on feedstock availability estimates, three plant sizes were studied: 907 T/day, 272 T/day, and 27 T/day. The necessary selling price of hydrogen produced by steam reforming syngas from the Battelle Columbus Laboratories indirectly heated biomass gasifier falls within current market values for the large and medium size plants within a wide range of feedstock costs. Results show that the small scale plant does not produce hydrogen at economically competitive prices, indicating that if gasification is used as the upstream process to produce hydrogen, local refueling stations similar to current gasoline stations, would probably not be feasible.

    Analysing urban regions is essential for their correct monitoring and planning. This is mainly accounted for the sharp increase of people living in urban areas, and consequently, the need to manage them. At the same time there has been a rise in the use of spatial and statistical datasets, such as the Urban Atlas, which offers high-resolution urban land use maps obtained from satellite imagery, and the Urban Audit, which provides statistics of European cities and their surroundings. In this study, we analyse the relations between urban fragmentation metrics derived from Land Use and Land Cover (LULC) data from the Urban Atlas dataset, and socio-economic data from the Urban Audit for the reference years 2006 and 2012. We conducted the analysis on a sample of sixty-eight Functional Urban Areas (FUAs). One-date and two-date based fragmentation indices were computed for each FUA, land use class and date. Correlation tests and principal component analysis were then applied to select the most representative indices. Finally, multiple regression models were tested to explore the prediction of socio-economic variables, using different combinations of land use metrics as explanatory variables, both at a given date and in a dynamic context. The outcomes show that demography, living conditions, labour, and transportation variables have a clear relation with the morphology of the FUAs. This methodology allows us to compare European FUAs in terms of the spatial distribution of the land use classes, their complexity, and their structural changes, as well as to preview and model different growth patterns and socio-economic indicators.

    In the present study extensive HPLC-DAD, HPLC-ESI-MS and NMR analyses were undertaken in the aqueous preparations (decoctions, infusions) and tinctures of Tilia platyphyllos Scop inflorescences. The aim of this work was to examine in depth the qualitative and quantitative profile of the investigated preparations, which find until today wide applications in pharmaceutical and cosmetic industry, and to propose a validated method for their quality control. An HPLC-DAD-ESI-MS method was developed and optimised for the quantitative determination of the constituents. Marker constituents of Tiliae flos are the flavonoids, while the volatile content is also used for the quality control. However, the analyses of the non-volatile fraction gave complex chromatographic fingerprints containing simple phenolics and low molecular weight procyanidins. The use of different HPLC columns permitted a good separation of the constituents and enabled their quantitation, while HPLC-MS analyses permitted the detection of procyanidin oligomers. Overall, 31 constituents were detected and identified. Extensive preparative chromatographic investigations and 2D-NMR analyses allowed the characterisation of procyanidins as epicatechin derivatives. Finally, the HPLC method was validated and complied with ICH guidelines. This is the first report of detailed analysis of the chemical composition of Tiliae flos.

    Full Text Available We focused on the economic and environmental impacts of regional widespread use of Electric Vehicles (EV. Massive introduction of battery and plug-in hybrid EV will affect the regional energy consumption significantly and therefore, influence environment situations. In this study, we adopted performance price ratio to evaluate cost effectiveness of conventional vehicles and electric vehicles and introduced Grey Relational Analysis method to evaluate environmental changes. Sensitivity analyses indicate that electricity and gasoline price fluctuation will not significantly change cost effectiveness of conventional vehicles and that large scale introduction of EV requires improvement of EV’s driving range and adequate charging stations. Electricity generation system also needs to be adjusted to reduce incremental SO2 pollution.

    Telehealth is the delivery of health care at a distance, using information and communication technology. The major rationales for its introduction have been to decrease costs, improve efficiency and increase access in health care delivery. This systematic review assesses the economic value of one type of telehealth delivery--synchronous or real time video communication--rather than examining a heterogeneous range of delivery modes as has been the case with previous reviews in this area. A systematic search was undertaken for economic analyses of the clinical use of telehealth, ending in June 2009. Studies with patient outcome data and a non-telehealth comparator were included. Cost analyses, non-comparative studies and those where patient satisfaction was the only health outcome were excluded. 36 articles met the inclusion criteria. 22(61%) of the studies found telehealth to be less costly than the non-telehealth alternative, 11(31%) found greater costs and 3 (9%) gave the same or mixed results. 23 of the studies took the perspective of the health services, 12 were societal, and one was from the patient perspective. In three studies of telehealth to rural areas, the health services paid more for telehealth, but due to savings in patient travel, the societal perspective demonstrated cost savings. In regard to health outcomes, 12 (33%) of studies found improved health outcomes, 21 (58%) found outcomes were not significantly different, 2(6%) found that telehealth was less effective, and 1 (3%) found outcomes differed according to patient group. The organisational model of care was more important in determining the value of the service than the clinical discipline, the type of technology, or the date of the study. Delivery of health services by real time video communication was cost-effective for home care and access to on-call hospital specialists, showed mixed results for rural service delivery, and was not cost-effective for local delivery of services between

    An analytical methodology is developed for assessing alternative modes of generating electricity from hot dry rock (HDR) geothermal energy sources. The methodology is used in sensitivity analyses to explore relative system economics. The methodology used a computerized, intertemporal optimization model to determine the profit-maximizing design and management of a unified HDR electric power plant with a given set of geologic, engineering, and financial conditions. By iterating this model on price, a levelized busbar cost of electricity is established. By varying the conditions of development, the sensitivity of both optimal management and busbar cost to these conditions are explored. A plausible set of reference case parameters is established at the outset of the sensitivity analyses. This reference case links a multiple-fracture reservoir system to an organic, binary-fluid conversion cycle. A levelized busbar cost of 43.2 mills/kWh ($1978) was determined for the reference case, which had an assumed geothermal gradient of 40/sup 0/C/km, a design well-flow rate of 75 kg/s, an effective heat transfer area per pair of wells of 1.7 x 10/sup 6/ m/sup 2/, and plant design temperature of 160/sup 0/C. Variations in the presumed geothermal gradient, size of the reservoir, drilling costs, real rates of return, and other system parameters yield minimum busbar costs between -40% and +76% of the reference case busbar cost.

    Extremely low frequency electric and magnetic fields (ELF EMFs) are a common exposure for modern populations. The prevailing public-health protection paradigm is that quantitative exposure limits are based on the established acute effects, whereas the possible chronic effects are considered too uncertain for quantitative limits, but might justify precautionary measures. The choice of precautionary measures can be informed by a health-economics analysis (HEA). We consider four such analyses of precautionary measures that have been conducted at a national or state level in California, the Netherlands, the United Kingdom, and Israel. We describe the context of each analysis, examine how they deal with some of the more significant issues that arise, and present a comparison of the input parameters and assumptions used. The four HEAs are methodologically similar. The most significant qualitative choices that have to be made are what dose-response relationship to assume, what allowance if any to make for uncertainty, and, for a CBA only, what diseases to consider, and all four analyses made similar choices. These analyses suggest that, on the assumptions made, there are some low-cost measures, such as rephasing, that can be applied to transmission in some circumstances and that can be justifiable in cost-benefit terms, but that higher cost measures, such as undergrounding, become unjustifiable. Of the four HEAs, those in the United Kingdom and Israel were influential in determining the country's EMF policy. In California and Netherlands, the HEA may well have informed the debate, but the policy chosen did not stem directly from the HEA.

    Full Text Available En réponse à la question « L’analyse économique est-elle intemporelle ? », nous soulignons la diversité et la complexité du rapport au temps de l’analyse économique : la représentation du temps futur est au coeur de l’analyse des anticipations. La modélisation dynamique dans un cadre d’équilibre général conduit, quant à elle, à une représentation du monde comme succession d’équilibres. Enfin, l’investigation du temps historique à partir des hypothèses de rationalité économique constitue le paradigme de la « New Economic History ». Il ressort de ce bref survol que l’analyse économique ne néglige aucun des aspects du rapport au temps : temps passé, temps présent, temps futur.To answer this question, we develop three issues : first, the assessment of the future is the core issue in studying expectations; second, dynamic economic modeling often leads to represent Time as a series of economic equilibriums; lastly, the «New Economic History» investigates History using the rational behavior hypothesis. In that way, the three dimensions of Time, past, present, and future are taken into account by Economic Analyses.

    Yuqi, Chen; Xudong, Guo; Chunyan, Lv

    2017-04-01

    In recent years, China has witnessed rapid increase in the dependence of foreign oil import. In 2015, the primary energy consumption of China is 543 million tons, of which 328 million tons was imported. The total amount of imported foreign oil increased from 49.8% in 2008 to 60.41% in 2016. To address the national energy security and GHG emission reduction, China has made considerable progress in expanding renewable energy portfolio, especially liquid biofuels. However, under the pressure of high population and vulnerable food security, China's National Development and Reform Commission (NDRC) ruled that bioenergy is only allowed to be produced using non-cereal feedstock. In addition, the energy crops can only be planted on marginal land, which is the land not suitable for growing field crops due to edaphic and/or climatic limitations, and other environmental risks. Although there have been a number of studies about estimating the marginal land for energy plants' cultivation in China, as to the different definition of marginal land and land use data, the results are quite different. Furthermore, even if there is enough marginal land suitable for energy plants' cultivation, economic viability of cultivating energy plants on marginal land is critical. In order to analyze the availability and economic analyses of the marginal land for bioenergy production strategy, firstly, by using of the latest and most authoritative land use data, this study focused on the assessment of marginal land resources and bioenergy potential by planting five species of energy plants including Cassava, Jatropha curcas, Helianthus tuberous L, Pistacia chinensis, Xanthoceras sorbifolia Bunge. The results indicate that there are 289.71 million ha marginal land can be used for these five energy plants' cultivation, which can produce 24.45 million tons bioethanol and 8.77 million tons of biodiesel. Secondly, based on field survey data and literature reviews, we found that, from the farmers

    This paper investigates the relationship between electricity consumption and economic growth for OPEC members. The bounds test yields evidence of a long-run relationship between electricity consumption and economic growth for all OPEC members. Causality results suggest that economic growth is dependent on electricity consumption in five countries, less dependent in three countries, and independent in three countries. Because these countries do not necessarily share similar political and economic traits, no single universal policy implication can be inferred from the results. The disparities across these causality results, therefore, stress the importance of formulating causality explanations while taking into account the particularities of individual countries rather than blindly applying the conventional interpretations.

    Evidence consistently indicates that schizophrenia is a costly disease although it is not a high prevalence disorder. There are a few studies in developing countries but no study in Thailand reporting the cost of schizophrenia from a societal perspective. Health policy makers need to be aware of the cost of health care for people with schizophrenia as well as the economic burden on patients and families. This study aims to provide a detailed breakdown of the costs attributed to schizophrenia including the consumption of public health care resources by people with schizophrenia and the negative consequences on patients and families due to productivity losses. Data from a survey conducted in 2008 among people in treatment for schizophrenia were used to estimate annual medical costs for treatment including outpatient services, hospitalization and patient travel. Indirect costs were estimated for reported productivity losses of patients and families. Uncertainty analysis was performed using Monte Carlo simulation methods. We tested the sensitivity of varying assumptions about market wages to estimate productivity losses. All cost estimates are adjusted to 2008 using the Consumer Price Index and reported in Thai baht (THB). The average annual exchange rate of Thai baths to one US dollar was 33.5 in 2008. The annual overall cost of schizophrenia was estimated to be THB 87 000 (USD 2600) (95% CI: 83 000, 92 000) per person or THB 31 000 million (USD 925 million) (95% CI: 26 000, 37 000) for the entire population with schizophrenia in Thailand. Indirect costs due to high unemployment, absenteeism and presenteeism of patients and families accounted for 61% of the total economic burden of schizophrenia. The largest component of direct medical cost was for hospitalizations (50%), followed by outpatient services and drug costs. Sensitivity analyses suggest that using labor force survey and socioeconomic status survey provided similar results, while lost productivity when the

    Residential care infrastructure, in terms of the characteristics of the organisation (such as proprietary status, size, and location) and the physical environment, have been found to directly influence resident outcomes. This review aimed to summarise the existing literature of economic evaluations of residential care infrastructure. A systematic review of English language articles using AgeLine, CINAHL, Econlit, Informit (databases in Health; Business and Law; Social Sciences), Medline, ProQuest, Scopus, and Web of Science with retrieval up to 14 December 2015. The search strategy combined terms relating to nursing homes, economics, and older people. Full economic evaluations, partial economic evaluations, and randomised trials reporting more limited economic information, such as estimates of resource use or costs of interventions were included. Data was extracted using predefined data fields and synthesized in a narrative summary to address the stated review objective. Fourteen studies containing an economic component were identified. None of the identified studies attempted to systematically link costs and outcomes in the form of a cost-benefit, cost-effectiveness, or cost-utility analysis. There was a wide variation in approaches taken for valuing the outcomes associated with differential residential care infrastructures: 8 studies utilized various clinical outcomes as proxies for the quality of care provided, and 2 focused on resident outcomes including agitation, quality of life, and the quality of care interactions. Only 2 studies included residents living with dementia. Robust economic evidence is needed to inform aged care facility design. Future research should focus on identifying appropriate and meaningful outcome measures that can be used at a service planning level, as well as the broader health benefits and cost-saving potential of different organisational and environmental characteristics in residential care.

    Understanding the cost-effectiveness and the role of economic and policy instruments, such as the combined product tax-recycling subsidy scheme or a tradable permit, for scrap tire recycling has been of crucial importance in a market-oriented environmental management system. Promoting product (tire) stewardship on one hand and improving incentive-based recycling policy on the other hand requires a comprehensive analysis of the interfaces and interactions in the nexus of economic impacts, environmental management, environmental valuation, and cost-benefit analysis. This paper presents an assessment of the interfaces and interactions between the implementation of policy instruments and its associated economic evaluation for sustaining a scrap tire recycling program in Taiwan during the era of the strong economic growth of the late 1990s. It begins with an introduction of the management of the co-evolution between technology metrics of scrap tire recycling and organizational changes for meeting the managerial goals island-wide during the 1990s. The database collected and used for such analysis covers 17 major tire recycling firms and 10 major tire manufacturers at that time. With estimates of scrap tire generation and possible scale of subsidy with respect to differing tire recycling technologies applied, economic analysis eventually leads to identify the associated levels of product tax with respect to various sizes of new tires. It particularly demonstrates a broad perspective of how an integrated econometric and engineering economic analysis can be conducted to assist in implementing policy instruments for scrap tire management. Research findings indicate that different subsidy settings for collection, processing, and end use of scrap tires should be configured to ameliorate the overall managerial effectiveness. Removing the existing boundaries between designated service districts could strengthen the competitiveness of scrap tires recycling industry, helping to

    Promoting use of pharmaco-economic models by formulary reviewers is a goal of the Academy of Managed Care Pharmacy (AMCP) Format for Formulary Submissions, but relatively few decision makers use such models, and many doubt that they provide meaningful input. To demonstrate how sophisticated disease-based pharmaco-economic models can aid formulary decision makers when long-term outcomes data are lacking. The Center for Outcomes Research (CORE) Diabetes Model (CDM), a published, validated Markov pharmaco-economic model that projects clinical and economic endpoints, was used to model the cost-effectiveness of exenatide, a new injectable antidiabetic agent that enhances glucose-dependent insulin secretion, in a standard cohort of type 2 diabetes patients (mean body mass index [BMI] = 27.5 3 kg/m2), compared with a modified obese cohort (mean BMI = 35 3 kg/m2) that was otherwise demographically identical at baseline to the standard cohort. The standard cohort was assumed to maintain baseline weight during treatment, and the modified obese cohort was assumed to experience weight loss of approximately 9% (mean = 3 kg/m2), with corresponding improvements in blood pressure, low density lipoprotein cholesterol, and triglycerides. We selected a 30-year time horizon because it was the time interval during which the CDM predicted most of the subjects would have died, and the costs obtained thus reasonably projected lifetime total direct medical costs for these cohorts. While treatment options certainly will change over a 30-year period, our goal was to estimate the incremental effect of exenatide over other available therapies. The model predicted reduced long-term treatment costs in obese patients, driven by an 11% decrease in cardiovascular disease burden and derived from the presumed weight loss. The incremental cost-effectiveness ratio (ICER) for adding exenatide over 3 years was 35,000 dollars/quality-adjusted life-year (QALY). Using a 30-year horizon, ICER values were 13

The processing firms operating in this area are characterized by significant investments in fixed assets and working capital. The article analyzes the annual account data of a sample of firms, showing that economic margins traditionally applied to assess the sustainability of the business cycle differ significantly from financial margins; also, the Interest Coverage Ratios (ICRs differ if calculated by applying an economic or a financial approach. Moreover, the annual account data highlight difficult credit access, expressed by applying a multiple regression model to analyze Free Cash Flow to Equity (FCFE generation. The article suggests a useful metric to measure more correctly the sustainability of a firm’s management that could be applied to others in the agri-food sector, particularly if characterized by a capital-intensive processing cycle.

    Are microalgae a potential energy source for biofuel production? This paper presents the laboratory results from a Nannochloropsis sp. microalga biorefinery for the production of oil, high-value pigments, and biohydrogen (bioH2). The energy consumption and CO2 emissions involved in the whole process (microalgae cultivation, harvest, dewater, mill, extraction and leftover biomass fermentation) were evaluated. An economic evaluation was also performed. Oil was obtained by soxhlet (SE) and supercritical fluid extraction (SFE). The bioH2 was produced by fermentation of the leftover biomass. The oil production pathway by SE shows the lowest value of energy consumption, 177-245 MJ/MJ(prod), and CO2 emissions, 13-15 kgCO(2)/MJ(prod). Despite consuming and emitting c.a. 20% more than the SE pathway, the oil obtained by SFE, proved to be more economically viable, with a cost of 365€/kg(oil) produced and simultaneously extracting high-value pigments. The bioH2 as co-product may be advantageous in terms of product yield or profit. Copyright © 2013 Elsevier Ltd. All rights reserved.

    This study aimed to identify the environmental and economic aspects of the wind-hydrogen system using life cycle assessment (LCA) and life cycle costing (LCC) methodologies. The target H{sub 2} pathways are the H{sub 2} pathway of water electrolysis (WE) with wind power (WE[Wind]) and the H{sub 2} pathway of WE by Korean electricity mix (WE[KEM]). Conventional fuels (gasoline and diesel) are also included as target fuel pathways to identify the fuel pathways with economic and environmental advantages over conventional fuels. The key environmental issues in the transportation sector are analyzed in terms of fossil fuel consumption (FFC), regulated air pollutants (RAPs), abiotic resource depletion (ARD), and global warming (GW). The life cycle costs of the target fuel pathways consist of the well-to-tank (WTT) costs and the tank-to-wheel (TTW) costs. Moreover, two scenarios are analyzed to predict potential economic and environmental improvements offered by wind energy-powered hydrogen stations. In LCA results, WE[Wind] is superior to the other pathways in all environmental categories. The LCC results show that the projected WTT cost savings of WE[Wind] and WE[KEM] compared to gasoline are US $ 0.050 and US $ 0.036 per MJ, respectively, because hydrogen will not be subjected to any fuel tax according to the Korean Energy Policy in 2015. Although WE[KEM] and WE[Wind] incur high capital costs owing to the required capital investment in fuel cell vehicles (FCVs), they have lower well-to-wheel (WTW) costs than those of conventional fuels due to the high FCV efficiency in fuel utilization stage. WTW costs for gasoline are higher than those of WE[KEM] and WE[Wind] by US $ 12,600 and US $ 10,200, respectively. This study demonstrated the future competitiveness of the WE[Wind] pathway in both environmental and economic aspects. In the WTT stage, the point-of-sale of the electricity produced by the wind power plant (WPP) cannot be controlled because the wind

    Over the past 25 years more than 20 major studies have examined the technological potential to improve the fuel economy of passenger cars and light trucks in the US. The majority has used technology/cost analysis, a combination of analytical methods from the disciplines of economics and automotive engineering. In this paper the authors describe the key elements of this methodology, discuss critical issues responsible for the often widely divergent estimates produced by different studies, review the history of its use, and present results from six recent assessments. Whereas early studies tended to confine their scope to the potential of proven technology over a 10-year time period, more recent studies have focused on advanced technologies, raising questions about how best to include the likelihood of technological change. The paper concludes with recommendations for further research.

    Full Text Available Bridging the gap between countries, and thus decresing poverty, is the greatest challenge of European countries in the context of the European social cohesion. The risk of future economic difficulties caused by the size of budget deficits is beared by the funds to be allocated to social inclusion in the EU and the EU member countries. They will be concerned in the post-crisis period with aligning the requirements of progress, of poverty reduction, but also of ensuring the sustainability of public finances. For Romania, cohesion is particularly important as most regions show significant differences as compared to the EU average and the national average. This group also includes the South Muntenia Region, which has many advantages for faster progress and to be able to exploit the opportunities offered by the implementation of the Europe 2020 strategy.

    The study analyses the effect of different factors (yields, production costs, methane yields, amount of co-substrates, investment costs and economies of scale) on the profitability of crops as inputs in biogas production plants. The profitability of silages from perennial ryegrass, alfalfa, maize and barley varies mainly within positive economic results, while rapeseed, hemp and topinambur mainly present a range of negative results. Fresh rye and silages from rye and wheat show equal positive and negative variation of results. Even the economic result of biogas plants is determined by investment costs, the sum of effects resulting from variations of yields, co-substrate production costs, amount of co-substrates, methane yields and economies of scales is decisive for the profitability of biogas plants.

    The purpose of this review was to describe cost-effectiveness and cost analysis studies across treatment modalities for squamous cell carcinoma of the head and neck (SCCHN), while placing their results in context of the current clinical practice. We performed a literature search in PubMed for English-language studies addressing economic analyses of treatment modalities for SCCHN published from January 2000 to March 2013. We also performed an additional search for related studies published by the National Institute for Health and Clinical Excellence in the United Kingdom. Identified articles were classified into 3 clinical approaches (organ preservation, radiation therapy modalities, and chemotherapy regimens) and into 2 types of economic studies (cost analysis and cost-effectiveness/cost-utility studies). All cost estimates were normalized to US dollars, year 2013 values. Our search yielded 23 articles: 13 related to organ preservation approaches, 5 to radiation therapy modalities, and 5 to chemotherapy regimens. In general, studies analyzed different questions and modalities, making it difficult to reach a conclusion. Even when restricted to comparisons of modalities within the same clinical approach, studies often yielded conflicting findings. The heterogeneity across economic studies of SCCHN should be carefully understood in light of the modeling assumptions and limitations of each study and placed in context with relevant settings of clinical practices and study perspectives. Furthermore, the scarcity of comparative effectiveness and quality-of-life data poses unique challenges for conducting economic analyses for a resource-intensive disease, such as SCCHN, that requires a multimodal care. Future research is needed to better understand how to compare the costs and cost-effectiveness of different modalities for SCCHN.

    Commercial-level sow replacement rates were investigated for a 10-yr planning horizon using a stochastic life-cycle swine production model. A three-tiered breeding structure was modeled for the production of market hogs in a three-breed static crossing scheme. Growth and reproductive traits of individual pigs were simulated using genetic, environmental, and economic parameters. Culling was after a maximum of 1, 5, or 10 parities in commercial levels within 1- and 5-parity nucleus and 1-, 5-, and 10-parity multiplier combinations. Yearly changes and average phenotypic levels were computed for pig and sow performance and economic measures. For growth traits, greater commercial level response was for systems with higher sow replacement rates, 110 to 115% of lowest response. Phenotypic changes in net returns ranged from $.85 to 1.01 x pig-1 x yr-1. Average growth performances were highest for systems with greatest genetic trend. Highest kilograms.sow-1 x year-1 finished was for 10-parity commercial alternatives. System differences in total costs and returns per pig resulted primarily from differences in replacement costs. Removal of the gilt system from analyses often reduced ranges among systems for economic measures by more than 70%. Systems with the lowest commercial replacement rates were most profitable. Within these systems, those with higher genetic change had highest net returns. For high replacement rates, no more than 175% of market value could be paid for gilts, but with lower sow replacement rates commercial units could justify as much as 450%.

    Full Text Available The present study is meant to be a first step towards the investigation of two current issues: the organization’s demand for highly professional services and the business consulting firms’ response as a challenge for the ethic imperatives. The main question raised is whether the national business consulting firms are liable to provide the economic and risk analyses required by the ambitious internationalization projects of small and medium enterprises (SMEs, and if not, what should be the firms’ ethical approach. In this respect, preliminary conclusions were made after testing the deliverables of several business consulting firms which were contracted to elaborate intricate economic and risk analyses of an internationalization project developed by a medium enterprise. The proven level of expertise of the contracted firms did not confirm their claims and assurances that they were fit for the job. This is why the rationale of today’s business consulting firms should be taken into account for further consideration while the exigency for increased savvy should become a priority.

    Full Text Available The present study deals with geochemical and petrographic analysis of the Kirana Hill shield rocks of Punjab plains from Buland, Hachi, Shaheen Abad, Shaikh and Machh hills. On basis of the current studies certain modifications have been made in the classification and nomenclature of rocks exposed in the study areas. Chemical analyses have also been carried out in order to calculate Cross Iddings, Pirsson, and Washington (CIPW norms”, to strengthen nomenclature scheme and finally rocks are classified by using “MAGMA SOFTWARE”. Rhyolites predominate over the basalts/dolerites, andesites, and phyllite/ slate. Rhyolitic rocks are light grey, greenish grey and light brown in color, aphanitic in nature. The observed microscopic textures are aphyric, phyric or porphyritic and micropoikilitc. Moreover, some rhyolitic rocks also show flow texture. They are either cryptocrystalline to microcrystalline or microcrystalline to cryptocrystalline. No glassy material has been observed in any thin section. Mafic rocks are characterized by the presence of ferromagnesian minerals with plagioclase. Andesites exhibit mainly porphyritic texture, but aphyric texture has also been observed in few samples. Hydrothermal alterations are also very common in these rocks. Other rock assemblages identified during laboratory studies from Kirana area include: tuffs i.e. (Lithic Crystal Tuff and Lithic Tuff, basaltic andesite, rhyodacite/ dacite, slate/ phyllite, ankeritic rocks/ veins and quartzofeldspathic veins. Our studies also reveal that no evidence of quartzite has been found in the samples collected from above mentioned areas of Kirana, although it has been reported in previous literature. Iron (Fe has been observed in rhyolite as well as other volcanic rocks of Kirana hills, its presence suggests magma from deep mantle instead of crustal melting / anatexis.

    While preparing an anticancer drug, even if it is an expensive molecular target drug, the remainder is not divided and saved for use in other patients; instead, it is discarded, resulting in waste of medical resources. In this study, we examined the economic loss in terms of medical costs by calculating the discarded amounts of 12 commonly used molecular target drugs at Ogaki Municipal Hospital, Japan between January 2012 and December 2014. We found, on average, that drugs valued at ¥ 52,593,182 were discarded annually. In particular, the discarded amounts of relatively expensive drugs, such as bevacizumab, bortezomib, and rituximab, were valued at ¥ 16,646,300, ¥ 15,866,289, and ¥ 8,401,324, respectively. Among these, the average amount of waste per administration of bortezomib was particularly expensive, at a cost of ¥ 67,325. Bortezomib is a commonly used treatment, resulting in excessive cumulative discarded cost. In an effort to save cost, we should consider using small capacity standard injections. Development of a simulation that used the remaining drug contents from only 1 day showed that bevacizumab alone accounts for an average cost saving of ¥1 2,542,191(75.3%) per year. This study suggests that effectively utilizing the remaining drug contents would ensure efficient use of medical resources, thereby reducing economic losses.

    Growth of titanium oxide (TiO2) nanoparticles of varying size, ranging from 20-60 nms through a versatile and an economic route, is being reported. The approach is based on a simple reaction of titanium powder and De-Ionized (DI) water at ∼180 °C, without use of any harmful additives. Field Emission Scanning Electron Microscopy (FESEM) reveals the well defined morphology of nanoparticles, whereas X-ray Diffraction (XRD) studies reveal that the, as prepared, nanoparticles are in a mixed phase, with a dominance of a stable rutile phase. Since only water, which is regarded as a benign solvent, is used during the preparation of nanoparticles, we believe that the products so produced are biocompatible and bio-safe and can be readily used for medical applications. The biocompatibility tests are yet to be carried out and shall be reported in forthcoming publications. © 2011 Sharif University of Technology. Production and hosting by Elsevier B.V.

    Eco prep (Economic Preparation) is the sustainable technology for preparing ceramic bodies with a minimum consumption of resources. It has a huge impact on the energy balance and eliminates the need for additives to generate a high-quality slip to make granules. In consequence Eco prep delivers a significant reduction in production costs, bringing an investment in this technology to the break-even point after a very short time. Reduction in water consumption and additives and the use of new raw materials are other advantages that impulse the implementation of this production technology, as well as important reduction of CO{sub 2} emissions, contributing to meeting the goals of the Kyoto Protocol. In short: A technology already successfully applied in different industries for decades, that includes a compendium of measures based on saving reductions in a range from 66% (energy, water,) and 100% (additives, deflocculants, etc.) and will mark the future in micro granulation processes also in the ceramic industry.

    Dental care for elderly nursing home residents is traditionally provided at fixed dental clinics, but domiciliary dental care is an emerging alternative. Longer life expectancy accompanied with increased morbidity, and hospitalisation or dependence on the care of others will contribute to a risk for rapid deterioration of oral health so alternative methods for delivering oral health care to vulnerable individuals for whom access to fixed dental clinics is an obstacle should be considered. The aim was to analyse health economic consequences of domiciliary dental care for elderly nursing home residents in Sweden, compared to dentistry at a fixed clinic. A review of relevant literature was undertaken complemented by interviews with nursing home staff, officials at county councils, and academic experts in geriatric dentistry. Domiciliary dental care and fixed clinic care were compared in cost analyses and cost-effectiveness analyses. The mean societal cost of domiciliary dental care for elderly nursing home residents was lower than dental care at a fixed clinic, and it was also considered cost-effective. Lower cost of dental care at a fixed dental clinic was only achieved in a scenario where dental care could not be completed in a domiciliary setting. Domiciliary dental care for elderly nursing home residents has a lower societal cost and is cost-effective compared to dental care at fixed clinics. To meet current and predicted need for oral health care in the ageing population alternative methods to deliver dental care should be available.

    Full Text Available Modern society is characterised not only by a fascination with scientific technology as a means of solving all problems, especially those that stand in the way of material progress (technicism, but also by an obsessive interest in everything that has to do with money (economism or mammonism. The article discusses the relationship between technicism and economism, on the basis of their relationship to utilitarian thinking: the quest for the greatest happiness for the greatest number of people. Recent major studies of neo-liberalism (seen as an intensification of utilitarianism by Laval and Dardot are used as reference to the development of utilitarianism. It is suggested that the western view of the world, as expressed in economism and technicism, with a utilitarian ethics, features three absolutisations: those of theoretical thinking, technology and economics. In a second part, the article draws on the framework of reformational philosophy to suggest an approach that, in principle, is not marred by such absolutisations.

    A facile widely spread technique employed to produce low-cost high-yield oxide powders, combustion synthesis, was used to prepare yttrium oxyfluoride crystalline ceramic powders. The structure of the powders was analyzed by X-ray powder diffraction and Rietveld refinement. Samples heat treated at 700 °C had a predominance of vernier orthorhombic Y6O5F8 phase, while samples heat treated at 800 °C crystallized in stoichiometric rhombohedral YOF phase. The samples were doped with luminescent europium trivalent ions (Eu3+) in different concentrations (1-15 wt.%) and Judd-Ofelt theory was used to probe the distortion from the inversion symmetry of the local crystal field and the degree of covalency between the rare-earth ion and the surrounding ligands. The luminescence lifetime was measured and the luminescence quantum efficiency (LQE) was estimated. We observed that Eu3+:Y6O5F8 samples presented higher LQE in spite of the larger local crystal field anisotropy found for Eu3+:YOF samples.

    Nurudeen ABU

    2010-05-01

    Full Text Available The controversy surrounding the direction of causality between saving and economic growth motivated this study. The author employed the Granger-causality and co-integration techniques to analyze the relationship between saving and economic growth in Nigeria during the period 1970-2007. The Johansen co-integration test indicates that the variables (economic growth and saving are co-integrated, and that a long-run equilibrium exists between them. In addition, the granger causality test reveals that causality runs from economic growth to saving, implying that economic growth precedes and granger causes saving. Thus, we reject the Solow’s hypothesis that saving precedes economic growth, and accept the Keynesian theory that t is economic growth that leads to higher saving. The author recommends that government and policy makers should employ policies that would accelerate economic growth so as to increase saving.

    There is a growing appetite for large complex databases that integrate a range of personal, socio-demographic, health, genetic and financial information on individuals. It has been argued that 'Big Data' will provide the necessary catalyst to advance both biomedical research and health economics and outcomes research. However, it is important that we do not succumb to being data rich but information poor. This paper discusses the benefits and challenges of building Big Data, analysing Big Data and making appropriate inferences in order to advance cancer care, using Cancer 2015 (a prospective, longitudinal, genomic cohort study in Victoria, Australia) as a case study. Cancer 2015 has been linked to State and Commonwealth reimbursement databases that have known limitations. This partly reflects the funding arrangements in Australia, a country with both public and private provision, including public funding of private healthcare, and partly the legislative frameworks that govern data linkage. Additionally, linkage is not without time delays and, as such, achieving a contemporaneous database is challenging. Despite these limitations, there is clear value in using linked data and creating Big Data. This paper describes the linked Cancer 2015 dataset, discusses estimation issues given the nature of the data and presents panel regression results that allow us to make possible inferences regarding which patient, disease, genomic and treatment characteristics explain variation in health expenditure.

    (NHES) reference case studies to (1) introduce sustainability metrics, such as life cycle assessment, (2) demonstrate the methods behind exergy and exergoeconomic analyses, (3) provide an economic analysis of the potential for SMR development from first-of-a-kind (FOAK) to nth-of-a-kind (NOAK), thereby illustrating possible cost reductions and deployment flexibility for SMRs over large conventional nuclear reactors, (4) assess the competitive potential for incorporation of storage and hydrogen production in NHES and in regulated and deregulated electricity markets, (5) compare an SMR-hydrogen production plant to a natural gas steam methane reforming plant using the SEF, and (6) identify and review the social considerations which would support future nuclear development domestically and abroad, such as public and political/regulatory needs and challenges. The Global Warming Potential (GWP) for the SMR (300 MWth)-wind (60 MWe)-high temperature steam electrolysis (200 tons Hydrogen per day) system was calculated as approximately 874 g CO2-equivalent as part of the life cycle assessment. This is 92.6% less than the GWP estimated for steam methane reforming production of hydrogen by Spath and Mann. The unit exergetic and exergoeconomic costs were determined for each flow within the NHES system as part of the exergy/exergoeconomic cost analyses. The unit exergetic cost is lower for components yielding more meaningful work like the one exiting the SMR with a unit exergetic cost of 1.075 MW/MW. In comparison, the flow exiting the turbine has a very high unit exergetic cost of 15.31, as most of the useful work was already removed through the turning of the generator/compressor shaft. In a similar manner, the high unit exergoeconomic cost of 12.45/MW*sec is observed for the return flow to the reactors, because there is very little exergy present. The first and second law efficiencies and the exergoeconomic factors were also determined over several cases. For the first or base SMR

    High temperature nuclear reactors will address mainly the industrial cogeneration market and compete with gas cogeneration, the current reference technology. The key question for HTR is therefore: how far are HTRs competitive against gas technologies? This simple question demands a complex response. First, the cogeneration scheme has to be discussed according the specificities in heat usage of every industry as they will impact the design. Second, the costs, revenues and risks of the different lifecycle phases for both a HTR and gas cogeneration plant have to be assessed and compared. These parameters will greatly depend on each location (personnel costs, gas local prices, CO{sub 2} pricing, etc.). A particular attention has to be given to the risk interactions between the cogeneration plant and the industrial facility it is supplying with heat and electricity (e.g. tritium contamination in industrial processes, explosion of flammable products in industrial site). This paper aims mainly at starting exchanges at international level with other equivalent initiatives in order to assess in general terms the economic viability of HTR worldwide, in relation to the evaluation of the HTR global market.

    Full Text Available Different methods were used for preparation of samples of rumen and caecum content from reindeer. The mineral contents of the samples were compared. Rumen and caecum samples from three reindeer were centrifuged at sampling and the fluid was stored frozen. Further preparation of these samples caused a gradient in mineral concentration at centrifugation, varying between samples. This procedure consequently gave no reliable results. Hence, three methods of preparing total rumen content after freezing were compared: centrifugation, wet and dry ashing (after drying. Na, K, Mg, Ca, Mn, Fe, Cu and Zn were analysed. The mineral analyses of rumen fluid, 41 compared to total rumen content, gave divergent results for the different minerals, depending on solubility. Wet ashing and dry ashing gave approximately the same results. Considering these results, analyses of minerals in samples of total rumen or caecum content is recommended, rather than analyses in fluid samples. The samples should be frozen or dried immediately at collection, and later be used for either wet or dry ashing.Olika metoder vid preparering av vom- och blindtarmsinnhåll från ren (Rangifer tarandus tarandus för analys av mineraler.Abstract in Swedish / Sammanfattning: Prov av vom- och blindtarmsinnehåll från ren preparerades på olika sätt och mineralåmnesinnehållet i proverna jämfördes.

    The Danish Energy Agency has initiated an analysis of the socio-economic sustainability of a CCS / EOR system based on CO{sub 2} capture from Danish sources and injected into selected Danish North Sea oil fields. The analysis shall assess the socioeconomic consequences of such a project as well as highlight the budgetary economic effects for the parties involved. Taking into account a realistic time frame for conversion of the cogeneration power plants and for the extent of the possible capture of CO{sub 2} in each of these plants, it has been chosen only to presuppose the establishment of CCS in three plants, namely Studstrupvaerket, Fynsvaerket and Nordjyllandsvaerket. Only the oil fields Dan, Halfdan and Gorm were selected for the analysis. The analysis shows that in the selected oil fields it is possible to increase the oil production by approx. 151 million. barrels of oil to the year 2049, which corresponds to approx. 40% of the estimated potential in these fields. The increased oil production requires that approx. 95 million. tonnes of CO{sub 2} is captured in the three power plants, which are subsequently transported and injected in the oil fields in the North Sea. The transport of CO{sub 2} from the CHP plants to the North Sea are assumed to be done by ship, since this solution is economically favorable and also offers logistical advantages and increased flexibility. The analysis shows that both the budget economic and the socio-economic analysis as a whole provide a positive economic net present value over a 30-year period. The socio-economic benefit is expected to be about. 3.5 billion DKK higher. This difference is due to especially the following conditions: a) CO{sub 2} emissions of CO{sub 2} transport are only included in the socio-economic analysis, since shipping is outside the quota system. In the socio-economic analysis, the estimated value of damage impact on the environment is included; b) The value of the oil produced after 2049 is included in

    Low- and middle-income countries need to consider economic issues such as cost-effectiveness, affordability and sustainability before introducing a program for human papillomavirus (HPV) vaccination. However, many such countries lack the technical capacity and data to conduct their own analyses. Analysts informing policy decisions should address the following questions: 1) Is an economic analysis needed? 2) Should analyses address costs, epidemiological outcomes, or both? 3) If costs are considered, what sort of analysis is needed? 4) If outcomes are considered, what sort of model should be used? 5) How complex should the analysis be? 6) How should uncertainty be captured? 7) How should model results be communicated? Selecting the appropriate analysis is essential to ensure that all the important features of the decision problem are correctly represented, but that the analyses are not more complex than necessary. This report describes the consensus of an expert group convened by the World Health Organization, prioritizing key issues to be addressed when considering economic analyses to support HPV vaccine introduction in these countries.

    The thermal decomposition (TD) methods are among the most successful in obtaining magnetic nanoparticles with a high degree of control of size and narrow particle size distribution. Here we investigated the TD of iron(III) acetylacetonate in the presence of oleic acid, oleylamine, and a series of alcohols in order to disclose their role and also investigate economically attractive alternatives for the synthesis of iron oxide nanoparticles without compromising their size and shape control. We have found that some affordable and reasonably less priced alcohols, such as 1,2-octanediol and cyclohexanol, may replace the commonly used and expensive 1,2-hexadecanediol, providing an economically attractive route for the synthesis of high quality magnetic nanoparticles. The relative cost for the preparation of Fe3O4 NPs is reduced to only 21% and 9% of the original cost when using 1,2-octanediol and cyclohexanol, respectively.

    Helminth infections are considered to be an important constraint on livestock productivity worldwide. The economic impact of these infections or their control strategies has traditionally been assessed by their effect on animal performance indicators or traditional economic calculation methods (e.g. budgeting and cost-benefit analysis). Because the impact of helminth infections has become more subtle and is farm-specific, one needs more refined economic evaluations of actions meant to increase or maintain the health of livestock on individual farms. This paper proposes an interdisciplinary framework that combines the developments in the veterinary control of helminth infections with economic performance measurements to identify farm-specific and profitable anthelmintic management decisions. Our framework positions individual farms' performance against performance benchmarks and is based on the farms' efficiency in transforming input(s) into output(s). We show how this positioning makes it possible to establish a linkage between input and output transformation, helminth infection levels and effects of control strategies. Furthermore, the framework allows for the identification of improvement paths that are not necessarily related to the helminth infection, but which may lead to other management improvements. We discuss the epidemiological information required and which complementary methods (e.g. efficiency analysis and budgeting techniques) can be used to make the framework operational.

    Evidence of a significant vaccine policy shift can be witnessed not only in the number of new vaccines available in Japan but also in the way that vaccine policy is being formulated. In 2010, policy makers decided for the first time ever to commission economic analyses as a reference in their consideration of subsidy allocation. This research offers a first hand account of the recent changes in vaccine policies by examining the decision-making process from the perspective of the researchers commissioned to perform the economic evaluations. In order to understand the vaccine policy-making process, a review was made of all the documents that were distributed and discussed during the government committee meetings from February 2010 when the revision of the Preventive Vaccination Law was initially proposed to May 2012 when the final recommendations were made. Economic evaluations were conducted for seven vaccines under consideration in the routine immunization program (Haemophilus influenzae type b or Hib, pneumococcal disease for children and adults, human papillomavirus, varicella, mumps, and hepatitis B). All were cost-effective options, except the Hib and hepatitis B vaccines. Nonetheless, all the vaccines were recommended equally for inclusion in the routine immunization program. While it is significant that policy-makers decided to commission economic assessments at all, various issues remain regarding the influence of external pressure, the choice of evaluation methods and the implications of using cost-effectiveness analyses on the future of Japanese health policy-making.

    For detailed reconstructions of atmospheric metal deposition using peat cores from bogs, a comprehensive protocol for working with peat cores is proposed. The first step is to locate and determine suitable sampling sites in accordance with the principal goal of the study, the period of time of interest and the precision required. Using the state of the art procedures and field equipment, peat cores are collected in such a way as to provide high quality records for paleoenvironmental study. Pertinent field observations gathered during the fieldwork are recorded in a field report. Cores are kept frozen at -18 degree C until they can be prepared in the laboratory. Frozen peat cores are precisely cut into 1 cm slices using a stainless steel band saw with stainless steel blades. The outside edges of each slice are removed using a titanium knife to avoid any possible contamination which might have occurred during the sampling and handling stage. Each slice is split, with one-half kept frozen for future studies (archived), and the other half further subdivided for physical, chemical, and mineralogical analyses. Physical parameters such as ash and water contents, the bulk density and the degree of decomposition of the peat are determined using established methods. A subsample is dried overnight at 105 degree C in a drying oven and milled in a centrifugal mill with titanium sieve. Prior to any expensive and time consuming chemical procedures and analyses, the resulting powdered samples, after manual homogenisation, are measured for more than twenty-two major and trace elements using non-destructive X-Ray fluorescence (XRF) methods. This approach provides lots of valuable geochemical data which documents the natural geochemical processes which occur in the peat profiles and their possible effect on the trace metal profiles.

    The report contains the contributions by the Institute of Food and Resource Economics (IFRO) to a Danish Government appraisal of greenhouse gas (GHG) reduction measures. The policy goal is a 40 per cent reduction in total Danish GHG emissions by 2020 compared to 1990. The GHGs analysed in the present study include emissions of CO{sub 2}, nitrous oxide and methane plus soil carbon sequestration. The purpose of the study is to identify GHG mitigation measures related to agriculture which can deliver cost-effective contributions to the targeted reduction in GHG emissions in Denmark. A total of 21 GHG mitigation measures are included in the assessment. The stipulated implementation period is 2013 to 2020. The cost calculations have a time horizon equal to 30 years, i.e. from 2013 to 2042. The GHG reduction potential, expressed in CO{sub 2} equivalents (CO{sub 2}-eq), is calculated as the sum of the effect on the emission of CO{sub 2} (with and without changes in soil carbon), methane and nitrous oxide. The 21 mitigation measures are listed below (figures in brackets show the assumed implementation potential): 1. Biogas from livestock manure/slurry (10 % of total slurry production) 2. Biogas from slurry and maize (10 % of total slurry production) 3. Biogas from organic clover 4. Additional fat in diet for dairy cows (80% of conventional dairy cow stock and 20 % of organic dairy cow stock) 5. Additional concentrated feed in diet for other cattle (25 % of cattle stock under 2 years of age) 6. Prolonged lactation period for dairy cows (10 % of dairy cow stock) 7. Acidification of slurry (10 % of total slurry production) 8. Covers on slurry containers (40 % of total slurry production) 9. Cooling of pig slurry (10 % of pig slurry) 10. Nitrification inhibitors in nitrate fertilisers (100 % of chemical fertilisers with nitrogen) 11. Increased nitrogen utilization requirement for degassed slurry in nitrogen quota system (50 % of total slurry production) 12. Increased nitrogen

    A project of the American Lymphedema Framework Project (ALFP), this review seeks to examine the policy and economic impact of caring for patients with lymphedema, a common side effect of cancer treatment. This review is the first of its kind undertaken to investigate, coordinate, and streamline lymphedema policy initiatives in the United States with potential applicability worldwide. As part of a large scale literature review aiming to systematically evaluate the level of evidence of contemporary peer-reviewed lymphedema literature (2004 to 2011), publications on care delivery models, health policy, and economic impact were retrieved, summarized, and evaluated by a team of investigators and clinical experts. The review substantiates lymphedema education models and clinical models implemented at the community, health care provider, and individual level that improve delivery of care. The review exposes the lack of economic analysis related to lymphedema. Despite a dearth of evidence, efforts towards policy initiatives at the federal and state level are underway. These initiatives and the evidence to support them are examined and recommendations for translating these findings into clinical practice are made. Medical and community-based disease management interventions, taking on a public approach, are effective delivery models for lymphedema care and demonstrate great potential to improve cancer survivorship care. Efforts to create policy at the federal, state, and local level should target implementation of these models. More research is needed to identify costs associated with the treatment of lymphedema and to model the cost outlays and potential cost savings associated with comprehensive management of chronic lymphedema.

    A scheme for remotely preparing an arbitrary five-qubit Brown state by using three three-qubit GHZ states as the quantum channel is proposed. It is shown that, after the sender performs two different three-qubit projective measurements, the receiver should introduce two auxiliary qubits and employ suitable C-NOT gates, Toffoli gate and unitary operations on his qubits, theoriginal state can be recovered with unit probability. Compared with the previous scheme, the advantage of the present scheme is that the entanglement resource can be reduced.

    Within the bounds of a research project, the authors of the contribution under consideration report on an extending analysis according to environmental protection and innovation. The stocktaking and evaluation of more important documents prove that despite the differences in the estimation of individual ranges an international consent insists according to central ecological challenges on global level. The consent covers the following target areas: Climate protection, preservation of the biological variety, water supply including waste water disposal and water protection, health protection. It is to be expected that in the next decades its validity will keep these ecological challenges although defusing or new environmental problems may result in single areas. It is to be expected that due to the world-wide economic development some emphasis of important ecological challenges will shift gradually to developing countries, in particular China and India.

    SAPO-34 membranes were synthesized by several routes towards N-2/CH4 separation. Membrane synthesis parameters including water content in the gel, crystallization time, support pore size, and aluminum source were investigated. High performance N-2-selective membranes were obtained on 100-nm-pore alumina tubes by using Al(i-C3H7O)(3) as aluminum source with a crystallization time of 6 h. These membranes separated N-2 from CH, with N-2 permeance as high as 500 GPU with separation selectivity of 8 at 24 degrees C. for a 50/50 N-2/CH4 mixture. Nitrogen and CH, adsorption isotherms were measured on SAPO-34 crystals. The N-2 and CH, heats of adsorption were 11 and 15 kJ/mol, respectively, which lead to a preferential adsorption of CE-H-4 over N-2 in the N-2/CH4 mixture. Despite this, the SAPO-34 membranes were selective for N-2 over CH4 in the mixture because N-2 diffuses much faster than CH4 and differences in diffusivity played a more critical role than the competitive adsorption. Preliminary economic evaluation indicates that the required N-2/CH4 selectivity would be 15 in order to maintain a CH4 loss below 10%. For small nitrogen-contaminated gas wells, our current SAPO-34 membranes have potential to compete with the benchmark technology cryogenic distillation for N-2 rejection. (C) 2015 Elsevier B.V.

    Recent avoidable failures in patient care highlight the ongoing need for evidence to support improvements in patient safety. According to the most recent reviews, there is a dearth of economic evidence related to patient safety. These reviews characterise an evidence gap in terms of the scope and quality of evidence available to support resource allocation decisions. This protocol is designed to update and improve on the reviews previously conducted to determine the extent of methodological progress in economic analyses in patient safety. A broad search strategy with two core themes for original research (excluding opinion pieces and systematic reviews) in 'patient safety' and 'economic analyses' has been developed. Medline, Econlit and National Health Service Economic Evaluation Database bibliographic databases will be searched from January 2007 using a combination of medical subject headings terms and research-derived search terms (see table 1). The method is informed by previous reviews on this topic, published in 2012. Screening, risk of bias assessment (using the Cochrane collaboration tool) and economic evaluation quality assessment (using the Drummond checklist) will be conducted by two independent reviewers, with arbitration by a third reviewer as needed. Studies with a low risk of bias will be assessed using the Drummond checklist. High-quality economic evaluations are those that score >20/35. A qualitative synthesis of evidence will be performed using a data collection tool to capture the study design(s) employed, population(s), setting(s), disease area(s), intervention(s) and outcome(s) studied. Methodological quality scores will be compared with previous reviews where possible. Effect size(s) and estimate uncertainty will be captured and used in a quantitative synthesis of high-quality evidence, where possible. Formal ethical approval is not required as primary data will not be collected. The results will be disseminated through a peer

    On a global scale, most beef is produced from grazing pastures or rangelands. Certain limitations exist, however, such as not having adequate animal rates of gain for marbling and availability of adequate forage nutritional value and quantity for constant animal weight gains. In the last 20 yr, there has been an increased interest in forage-fed beef for multiple reasons (health related, environmental concerns, and welfare issues). Starting on June 5, 13, 14, and 8 in 4 consecutive yr, 54 steers (initial BW=259±5.6 kg; average of 9 mo of age) were randomly allotted to 3 yr-round forage systems. Each system occupied 6 ha/replicate and had the same stocking rate. System 1 had annual ryegrass (Lolium multiflorum) for winter grazing and bermudagrass (Cynodon dactylon) for summer grazing; while Systems 2 and 3 added rye and a clover mix to the ryegrass and diversified the use of pastures in the fall (dallisgrass [Paspalum dilatatum] and clovers [Trifolium spp.]). System 3 added the use of annual summer forages. During their respective growing season for each forage or forage mix, mass and height did not limit animal performance; however, there was a sampling date effect (P0.05) were detected between systems in ADG year round, during the winter season, or carcass characteristics. Return over total direct costs and total specified expenses were greater for Systems 1 and 2, while System 3 was the lowest. Hay making and bale sales played a major role in explaining the economic results of this study. Where possible, year-round forage systems are a viable alternative for forage-fed beef production; however, the low gains during summer and forage availability during the transition period when hay is necessary deserve further research to find alternatives to improve productivity during those times of the year.

    The opportunity to apply a sampling plan was evaluated. Costs were computed by a microcosting study. In 2003, a sampling plan was defined to reduce the number of chemotherapy quality controls while preserving the same level of quality. Recent qualitative and quantitative changes led us to define a second sampling plan supplemented by an economic evaluation to determine the cost and cost-savings of quality control. The study considers preparation produced during four semesters classified into three groups. The first one includes drugs produced below 200 batches a semester. Group 2, those for which the lot of preparation lots would have been rejected twice among these four semesters. Group 3, those would have been accepted (≥3 'acceptable lot'). A single sampling plan by attributes was applied to this group with an acceptance quality level of 1.65% and a lot tolerance percent defective below 5%. A micro-costing study was conducted on quality control, from the sampling to the validation of the results. Among 39 cytotoxic drugs, 11 were sampled which enabled to avoid a mean of 17,512 control assays per year. Each batch of the 28 non-sampled drugs was however analyzed. Costs were estimated at 2.98€ and 5.25€ for control assays depending of the analytical method. The savings from the application of the sampling plans was 153,207€ in 6 years. The sampling plan allowed maintaining constancy in number of controls and the level of quality with significant costsavings, despite a substantial increase in drugs to assay and in the number of preparations produced.

    The analyses to economic systems were extended to fields of cooperative games. A process and main results of an economics experiment in cooperative games were introduced by using the method of economics experiments. There was deviation between participants' behavior and theoretical anticipation. The main reason to cause the deviation was players' demands for fairness. Compared experimental data with weight Banzhaf-coleman value and Shapley value, it showed that there was perfect consistency between experimental outcomes and theoretical solutions by introducing concept of weight Banzhaf-Coleman value.%将经济系统的分析扩展到合作博弈领域内.引入经济学实验的方法,介绍了一次在合作博弈范畴内的经济学实验的过程及其主要结果.实验参与者的行为与理论预期存在着偏离,造成该差异的主要原因在于局中人对公平性的要求.通过引入Banzhaf-coleman势值的概念,将实验数据与Banzhaf-coleman势值及Shapley值对比,显示出实验结果与理论解有着较好的相容性.

    Full Text Available Gas turbines incur a loss of output power during hot seasons due to high ambient air temperatures, and input air cooling systems are often used to partly offset this problem. Here, results are reported for an investigation of the utilization of a heat pump to cool the inlet air of a gas turbine compressor. The analyses are carried out for two climates: the city of Yazd, Iran, which has a hot, arid climate, and Tehran, Iran, which has a temperate climate. The heat pump input power is obtained from the gas turbine. The following parameters are determined, with and without the heat pump: net output power, first and second law efficiencies, quantities and costs of environmental pollutants, entropy generation and power generation. The results suggest that, by using the air-inlet cooling system, the mean output power increases during hot seasons by 11.5% and 10% for Yazd and Tehran, respectively, and that the costs of power generation (including pollution costs decrease by 11% and 10% for Yazd and Tehran, respectively. Also, the rate of generation of pollutants such as NOx and CO decrease by about 10% for Yazd and 35% for Tehran, while the average annual entropy generation rate increases by 9% for Yazd and 7% for Tehran, through air-inlet cooling. The average increase of the system first law efficiency is 2% and of the system second law efficiency is 1.5% with the inlet-air cooling system.

  4. Comments on the use of network structures to analyse commercial companies’ evolution and their impact on economic behaviour

    Costea, Carmen

    2006-10-01

    Network analysis studies the development of the social structure of relationships around a group or an institutional body, and how it affects beliefs and behaviours. Causal constraints require a special and deeper attention to the social structure. The purpose of this paper is to give a new approach to the idea that this reality should be primarily conceived and investigated from the perspective of the properties of relations between and within units, instead of the properties of these units themselves. The relationship may refer to the exchange of products, labour, information and money. By mapping these relationships, network analysis can help to uncover the emergent and informal communication patterns of commercial companies that may be compared to the formal communication structures. These emergent patterns can be used to explain institutional and individuals’ behaviours. Network analysis techniques focus on the communication structure of an organization that can be subdivided and handled with different approaches. Structural features that can be analysed through the use of network analysis techniques are, for example, the (formal and informal) communication patterns in an organization or the identification of specific groups within an organization. Special attention may be given to specific aspects of communication patterns.

  9. Extending transaction cost economics: towards a synthesised approach for analysing contracting in health care markets with experience from the Australian private sector.

    Science.gov (United States)

    Donato, Ronald

    2010-12-01

    Transaction cost economics (TCE) has been the dominant economic paradigm for analysing contracting, and the framework has been applied in a number of health care contexts. However, TCE has particular limitations when applied to complex industry settings and there have been calls to extend the framework to incorporate dynamic theories of industrial organisation, specifically the resource-based view (RBV). This paper analyses how such calls for theoretical pluralism are particularly germane to health care markets and examines whether a combined TCE-RBV provides a more comprehensive approach for understanding the nature of contractual arrangements that have developed within the Australian private health care sector and its implications for informing policy. This Australian case study involved a series of interviews with 14 senior contracting executives from the seven major health funds (i.e. 97% of the insured population) and seven major private hospital groups (i.e. 73% of the private hospital beds). Study findings reveal that both the TCE perspective with its focus on exchange hazards, and the RBV approach with its emphasis on the dynamic nature of capabilities, each provide a partial explanation of the developments associated with contracting between health funds and hospital groups. For a select few organisations, close inter-firm relational ties involving trust and mutual commitment attenuate complex exchange hazards through greater information sharing and reduced propensity to behave opportunistically. Further, such close relational ties also provide denser communication channels for creating and transmitting more complex information enabling organisations to tap into each other's complementary resources and capabilities. For policymakers, having regard to both TCE and RBV considerations provides the opportunity to apply competition policy beyond the current static notions of efficiency and welfare gains, and cautions policymakers against specifying ex ante the

    Full Text Available Agriculture-based irrigation communities of northern New Mexico have survived for centuries despite the arid environment in which they reside. These irrigation communities are threatened by regional population growth, urbanization, a changing demographic profile, economic development, climate change, and other factors. Within this context, we investigated the extent to which community resource management practices centering on shared resources (e.g., water for agricultural in the floodplains and grazing resources in the uplands and mutualism (i.e., shared responsibility of local residents to maintaining traditional irrigation policies and upholding cultural and spiritual observances embedded within the community structure influence acequia function. We used a system dynamics modeling approach as an interdisciplinary platform to integrate these systems, specifically the relationship between community structure and resource management. In this paper we describe the background and context of acequia communities in northern New Mexico and the challenges they face. We formulate a Dynamic Hypothesis capturing the endogenous feedbacks driving acequia community vitality. Development of the model centered on major stock-and-flow components, including linkages for hydrology, ecology, community, and economics. Calibration metrics were used for model evaluation, including statistical correlation of observed and predicted values and Theil inequality statistics. Results indicated that the model reproduced trends exhibited by the observed system. Sensitivity analyses of socio-cultural processes identified absentee decisions, cumulative income effect on time in agriculture, and land use preference due to time allocation, community demographic effect, effect of employment on participation, and farm size effect as key determinants of system behavior and response. Sensitivity analyses of biophysical parameters revealed that several key parameters (e.g., acres per

    Oligosaccharide chains of glycoconjugates are important biopolymers not only as carriers of information in cell-cell interactions but also as markers of cellular differentiation, aging, and malignant alteration. Molecular interactions where carbohydrates are involved are usually considered as weak interactions, so the study and evaluation of these interactions is still in its infancy. The evidences and studies of carbohydrate-carbohydrate interactions (CCI) will be confirming the importance of this mechanism for specific cell adhesion and communication. Their development will go hand in hand with the development of new and more sensitive techniques to study weak interactions. Recently, synthetic glycopolymers with functions similar to those of such natural carbohydrates and with specific pendant saccharide moieties were used as a solution for enhancement CCI when forming polyvalent interactions. Carbohydrates are ubiquitous components of cell wall membranes and occur as glycolipids, glycoproteins, proteoglycans, and capsular polysaccharides. As such they can participate in forefront intramolecular and intracellular events. Apart from their recognized roles in the physicochemical properties of glycolipids and glycoproteins. In this study, we designed trisaccharide monomers for free radical polymerization. Subsequently, the trisaccharide unit for chemical conjugation was synthesized from galactosamine in good yield. For further NMR analyses of CCI, glycopolymers composed of these sugar derivatives will be provided.

  14. Extended Analyses of the German IVF Registry (DIR: Andrological Aspects, Medical-Economical Assumptions Related to the Shift from IVF to ICSI and Stimulation with Gonadotropins

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available In addition to the annual report of the German IVF Registry (D·I·R the database of 498,784 ART cycles between 1998 and 2008 was analysed for aspects regarding andrology, medical and economical aspects of ICSI and stimulation with gonadotropins. The indication for an ICSI procedure is related to the retrieval of sperm. Seven percent of all ART cycles in the DIR are already performed with epididymal or testicular sperm due to azoospermia. The analysis of cycles with testicular sperm revealed that fertilisation and pregnancy rates are reduced in comparison to ejaculated or frozen sperm, but miscarriage and birth rates do not increase. The data recording of lifestyle parameters can be valuable in the future. The analysis of the D·I·R data demonstrates that restrictions on the reimbursement for ART cycles have significant impact on the use of IVF and ICSI treatments. Medical indications rather than economic reasons seem to be responsible for the increase in ICSI treatment. Since the commercial launch of GnRH antagonists in 1999 and 2000 more than 90 % of IVF and ICSI protocols in Germany are now performed with GnRH agonists (54.8 % and GnRH antagonists (31.5 %. Approximately 90% of the IVF and ICSI cycles in Germany are performed with recombinant FSH (rFSH, highly purified menotropin (HP-hMG or a combination of both. Non-medical factors can influence the choice of gonadotropins for stimulation. Women beyond the age of 34 probably have better IVF or ICSI outcome when the stimulation is performed with rFSH. J

    To assess the nutritional quality of prepared foods available to primary-school children. Prepared foods available in a public and private school were sampled daily for 4 weeks (a total of forty-five samples) and chemically analysed for protein, fat, carbohydrate, iron, salt and sodium. The results were compared to the nutritional standards for children aged 7-10 years. Alfenas, south-eastern Brazil. The concentration of protein, lipid, iron and sodium and the energy values of the foods at the private school were significantly higher than those at the public school. No differences were seen in the carbohydrate and salt values. The range of macronutrients was more balanced at the public school in relation to fat and protein. Foods at the private school were, in general, energy-dense. At both the public and private school, they provided the minimum energy and iron. Salt content was over twice the maximum amount, and that for sodium was over three times the amount, in both the public and private school. Overall, foods prepared at the public school were better nutritional quality than those at the private school and those offered in public schools in some developed countries. This finding can probably be explained by the fact that a nutritionist, as required by law, was responsible for planning the menus at the public school. However, corrective action is needed to adjust for the wide variability in energy and nutrient content during weekdays and in the sodium content of prepared foods available in both the public and private school.

    1998-08-01

    The main objective of this study was to analyse glycogen in single muscle fibres, using a recently developed microfluorometric method which detects subpicomol amounts of NADPH, glucose and glycogen (as glucosyl units) (detection limit 0.16-0.17 pmol in a 25 nl sample) without fluorochrome amplification. The fibres were freshly dissected from the twitch region of the iliofibularis muscle of the cane toad (Bufo marinus), and were mechanically skinned under paraffin oil to gain access to the intracellular compartments. The results show that (1) glycogen concentrations in toad skeletal muscle fibres range between 25.8 and 369 mmol glucosyl units/litre fibre volume; (2) there is a large variation in glycogen content between individual fibres from the iliofibularis muscle of one animal; (3) there are seasonal differences in the glycogen content of toad single muscle fibres; (4) the total amount of glycogen in single muscle fibres of the toad does not decrease significantly when storing the tissue, under paraffin oil, at 20-25 degree C for up to 6 h or at 4 degree C for up to 24 h; and (5) 15-26% of fibre glycogen can be washed in an aqueous solution at pH 5-7, within 5 min, while 74-85% of fibre glycogen remains associated with the washed skinned fibre, even after 40 min exposure of the skinned fibre preparation to the aqueous environment. The retention of most glycogen in the fibre preparation after mechanical removal of the plasma membrane and extensive washing indicates that in toad skeletal muscle fibres the largest proportion of glycogen is tightly bound to intracellular structures. The results also show that the skinned muscle fibre preparation is well suited for microfluorometric glycogen determination, since low molecular weight non-glycogen contributors to the fluorescence signal can be removed from the myoplasmic space prior to the glycogen hydrolysis step.

    The overall objectives of the project `Feasibility of electricity production from biomass by pressurized gasification systems` within the EC Research Programme JOULE II were to evaluate the potential of advanced power production systems based on biomass gasification and to study the technical and economic feasibility of these new processes with different type of biomass feed stocks. This report was prepared as part of this R and D project. The objectives of this task were to perform fuel analyses of potential woody and herbaceous biomasses with specific regard to the gasification properties of the selected feed stocks. The analyses of 15 Scandinavian and European biomass feed stock included density, proximate and ultimate analyses, trace compounds, ash composition and fusion behaviour in oxidizing and reducing atmospheres. The wood-derived fuels, such as whole-tree chips, forest residues, bark and to some extent willow, can be expected to have good gasification properties. Difficulties caused by ash fusion and sintering in straw combustion and gasification are generally known. The ash and alkali metal contents of the European biomasses harvested in Italy resembled those of the Nordic straws, and it is expected that they behave to a great extent as straw in gasification. Any direct relation between the ash fusion behavior (determined according to the standard method) and, for instance, the alkali metal content was not found in the laboratory determinations. A more profound characterisation of the fuels would require gasification experiments in a thermobalance and a PDU (Process development Unit) rig. (orig.) (10 refs.)

    Serial block-face imaging using scanning electron microscopy enables rapid observations of three-dimensional ultrastructures in a large volume of biological specimens. However, such imaging usually requires days for sample preparation to reduce charging and increase image contrast. In this study, we report a rapid procedure to acquire serial electron microscopic images within 1 day for three-dimensional analyses of subcellular ultrastructures. This procedure is based on serial block-face with two major modifications, including a new sample treatment device and direct polymerization on the rivets, to reduce the time and workload needed. The modified procedure without uranyl acetate can produce tens of embedded samples observable under serial block-face scanning electron microscopy within 1 day. The serial images obtained are similar to the block-face images acquired by common procedures, and are applicable to three-dimensional reconstructions at a subcellular resolution. Using this approach, regional immune deposits and the double contour or heterogeneous thinning of basement membranes were observed in the glomerular capillary loops of an autoimmune nephropathy model. These modifications provide options to improve the throughput of three-dimensional electron microscopic examinations, and will ultimately be beneficial for the wider application of volume imaging in life science and clinical medicine.

    The purpose of this study is to review the causal link in the Granger sense, between energy consumption and economic growth in Algeria, to determine its implications for economic policy. The analysis was done based on Granger static and causality tests using statistical data on per capita primary energy consumption and gross domestic product per inhabitant in Algeria, over the 1965-2008 period. The results of the survey show that there is, in Algeria, a strong link between energy consumption per inhabitant and GDP per inhabitant. The results also suggest the lack of a long term impetus (no co-integration) between energy consumption and economic growth. In addition, there is a one-way causal link between GDP and energy consumption, i.e. the prior GDP data provides a better forecast of energy consumption level, but not the contrary. In other words, GDP explains consumption, not the contrary. (author)

    BACKGROUND Gestational diabetes mellitus (GDM) is associated with a higher risk of important adverse outcomes. Practice varies and the best strategy for identifying and treating GDM is unclear. AIM To estimate the clinical effectiveness and cost-effectiveness of strategies for identifying and treating women with GDM. METHODS We analysed individual participant data (IPD) from birth cohorts and conducted systematic reviews to estimate the association of maternal glucose levels with adverse perinatal outcomes; GDM prevalence; maternal characteristics/risk factors for GDM; and the effectiveness and costs of treatments. The cost-effectiveness of various strategies was estimated using a decision tree model, along with a value of information analysis to assess where future research might be worthwhile. Detailed systematic searches of MEDLINE(®) and MEDLINE In-Process & Other Non-Indexed Citations(®), EMBASE, Cumulative Index to Nursing and Allied Health Literature Plus, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Health Technology Assessment database, NHS Economic Evaluation Database, Maternity and Infant Care database and the Cochrane Methodology Register were undertaken from inception up to October 2014. RESULTS We identified 58 studies examining maternal glucose levels and outcome associations. Analyses using IPD alone and the systematic review demonstrated continuous linear associations of fasting and post-load glucose levels with adverse perinatal outcomes, with no clear threshold below which there is no increased risk. Using IPD, we estimated glucose thresholds to identify infants at high risk of being born large for gestational age or with high adiposity; for South Asian (SA) women these thresholds were fasting and post-load glucose levels of 5.2 mmol/l and 7.2 mmol/l, respectively and for white British (WB) women they were 5.4 and 7.5 mmol/l, respectively.

    This study summarizes organic carbon isotope (δ13C) and total organic carbon (TOC) data from a series of tests undertaken to provide an appropriate methodology for pre-analysis treatment of mudstones from an Upper Carboniferous sedimentary succession, in order to develop a consistent preparation procedure. The main treatments involved removing both inorganic carbonate and hydrocarbons (which might be extraneous) before δ13C and TOC analysis. The results show that decarbonating using hydrochloric acid causes significant reduction in δ13C and total carbon (TC) of the bulk material due to the removal of inorganic carbonate. These changes are most pronounced where soluble calcium carbonate (rather than Ca-Mg-Fe carbonate) is present. Deoiled samples show only slightly higher mean δ13C where visible bitumen was extracted from the bulk sample. Moreover, the isotopic signatures of the extracts are closely correlated to those of their respective bulk samples, suggesting that small yields of hydrocarbons were generated in situ with no isotopic fractionation. In addition, further δ13C and TC analyses were performed on samples where mixing of oil-based drilling mud with brecciated core material had been undertaken. Brecciated mudstone material did not display distinct isotopic signals compared to the surrounding fine-grained material. Overall we show that the most accurate assessment of bulk organic carbon isotopes and concentration in these samples can be achieved through decarbonating the material prior to measurement via the `rinse method'. However, our results support recent findings that pre-analysis acid treatments can cause variable and unpredictable errors in δ13C and TOC values. We believe that, despite these uncertainties, the findings presented here can be applied to paleoenvironmental studies on organic matter contained within sedimentary rocks over a range of geological ages and compositions.

  15. ECOLOGICAL ECONOMICS VS ECONOMIC(AL ECOLOGY

    Full Text Available Currently world faces the dilemma – ecological economy or economic(al ecology. The researchers produce hundreds of surveys on the topic. However the analyses of recent most cited simulations had shown the diversity of results. Thus, for some states the Kuznets environmental curve has place, for others – no. Same could be said about different years for the same state. It provokes the necessity of drawing new group analyses to reveal the tendencies and relationships between economic and environmental factors. Most flexible and mirror factor of environmental sustainability is the volume of CO2 emissions. The econometric analysis was used for detecting the economic impact on this indicator at the global level and in the spectra of group of states depending on their income. The hypothesis of the existence of environmental Kuznets curve for the analysed data is rejected. Real GDP per capita impact on carbon dioxide emissions is considered only at the global level. The impact of openness of the economy is weak. Rejection happened also to the hypothesis that for the developed countries there is a reverse dependence between the environmental pollution and economic openness. Indicator “energy consumption per capita” impacts on greenhouse gas emissions only in countries with high income. Whereby it should be noted that the more developed a country is, the more elastic is this influence. These results have a potential usage for environmental policy regulation and climate strategy.

    Full Text Available The present study aims to synthesize SiAlON-based composites utilizing coal gangue. Different types of SiAlON-based composites were synthesized using coal gangue by carbothermal reduction nitridation method through control of different reaction atmospheres. The experimental results indicate that the oxygen partial pressure was an essential factor in the manufacture of SiAlON-based composites and under proper control of the atmospheres, SiAlON-based composites with different crystal structures could be synthesized. The optimum conditions of synthesis of different SiAlON-based composites were respectively determined. Based on the laboratory results, a prototype plant was proposed and constructed, and β-SiAlON composite was successfully produced using coal gangue. The synthesized β-SiAlON composite was applied in preparation of iron ladle brick instead of SiC, which showed that the compression strength, refractoriness under load and high temperature bending strength were increased from 44.5 ± 6.7 MPa, 1618 ± 21 °C and 5.4 ± 1.2 MPa to 64.1 ± 2.5 MPa, 1700 ± 28 °C and 7.1 ± 1.6 MPa, respectively. Compared with the traditional synthesis method, the present technique is expected to save energy both in raw materials and technical process.

    Over the second half of the Nineties, Snamprogetti and Snam, with the cooperation of ENI Divisione Agip, Saipem and EniTecnologie, have been working for a new concept of long distance (LD) transportation of natural gas via cross country pipelines, based on high pressure (HP) larger than the traditional 7.5 to 10 MPa, here called low pressure (LP), and advanced technologies. This paper describes the economic advantages of the new long distance high pressure (LDHP) gas transportation concept, in terms of investment and operating costs; the findings of the application of a mathematical model developed for the determination of the optimum pipe diameter and number of compression stations for both HP and LP alternatives are discussed. The economic comparison, referred to a representative case i.e. a transmission system of 5,000 km for a specified transport capacity of 15 to 30 x 10{sup 9} Sm{sup 3}/y, shows that the competitiveness of LDHP transportation increases with the increase of the flow rates, reaching a very remarkable advantage for quantities exceeding 10 x 10{sup 9} Sm{sup 3}/y. At present ENI Group companies are engaged in further development focused on the application of high grade steels (X-100), and aiming at obtaining further cost reduction while both ensuring the required system reliability and meeting the specified safety requirements.

    The overall objective of this project was to quantify the energy, environmental, and economic performance of industrial facilities that would coproduce electricity and transportation fuels or chemicals from a mixture of coal and biomass via co-gasification in a single pressurized, oxygen-blown, entrained-flow gasifier, with capture and storage of CO{sub 2} (CCS). The work sought to identify plant designs with promising (Nth plant) economics, superior environmental footprints, and the potential to be deployed at scale as a means for simultaneously achieving enhanced energy security and deep reductions in U.S. GHG emissions in the coming decades. Designs included systems using primarily already-commercialized component technologies, which may have the potential for near-term deployment at scale, as well as systems incorporating some advanced technologies at various stages of R&D. All of the coproduction designs have the common attribute of producing some electricity and also of capturing CO{sub 2} for storage. For each of the co-product pairs detailed process mass and energy simulations (using Aspen Plus software) were developed for a set of alternative process configurations, on the basis of which lifecycle greenhouse gas emissions, Nth plant economic performance, and other characteristics were evaluated for each configuration. In developing each set of process configurations, focused attention was given to understanding the influence of biomass input fraction and electricity output fraction. Self-consistent evaluations were also carried out for gasification-based reference systems producing only electricity from coal, including integrated gasification combined cycle (IGCC) and integrated gasification solid-oxide fuel cell (IGFC) systems. The reason biomass is considered as a co-feed with coal in cases when gasoline or olefins are co-produced with electricity is to help reduce lifecycle greenhouse gas (GHG) emissions for these systems.

    To protect climate, the aviation industry is asked to reduce GHG emissions. A possible measure to achieve this goal is the increased use of biokerosene. One possible way to provide biokerosene is through liquefaction of biomethane. This biomethane can be produced by anaerobic fermentation from large variety of organic waste streams. Considering this background, an overview of the overall process chain for the production of biokerosene from biomethane is given. The starting point for the analysis is the Gasto-Liquid-process (GtL). This process is described in detail focusing on the differences between autothermal and steam reforming of biomethane. Based on this, two reference concepts are designed, modeled, and simulated. The results of this simulation are then evaluated according to predefined technical parameters. Finally, the defined concepts are analyzed economically, i.e. the production costs are assessed and the key parameters defining the results are identified.

    To analyze the impacts of pharmaceutical sector policies implemented to contain country spending during the economic recession--a reference price system in Finland and a mix of policies including changes in reimbursement rates, a generic promotion campaign and discounts granted to the public payer in Portugal - on utilization of, as a proxy for access to, antipsychotic medicines. We obtained monthly IMS Health sales data in standard units of antipsychotic medicines in Portugal and Finland for the period January 2007 to December 2011. We used an interrupted time series design to estimate changes in overall use and generic market shares by comparing pre-policy and post-policy levels and trends. Both countries' policy approaches were associated with slight, likely unintended, decreases in overall use of antipsychotic medicines and with increases in generic market shares of major antipsychotic products. In Finland, quetiapine and risperidone generic market shares increased substantially (estimates one year post-policy compared to before, quetiapine: 6.80% [3.92%, 9.68%]; risperidone: 11.13% [6.79%, 15.48%]. The policy interventions in Portugal resulted in a substantially increased generic market share for amisulpride (estimate one year post-policy compared to before: 22.95% [21.01%, 24.90%]; generic risperidone already dominated the market prior to the policy interventions. Different policy approaches to contain pharmaceutical expenditures in times of the economic recession in Finland and Portugal had intended--increased use of generics--and likely unintended--slightly decreased overall sales, possibly consistent with decreased access to needed medicines--impacts. These findings highlight the importance of monitoring and evaluating the effects of pharmaceutical policy interventions on use of medicines and health outcomes.

    Emission of particles into the atmosphere is one of the biggest air pollution problems of our times. The emission of particles causes severe health problems such as respiratory and circulatory diseases, lung cancer, asthma, bronchitis and even causes premature deaths. The emission of particles comes from a number of different sources, where traffic is a considerable contributor. The effects of particle emissions from the traffic on the population are substantial, as the emission comes from mobile sources which create a high local pollution in city areas and in consequence high exposure of the local population. Exhaust particle emissions come mainly from diesel engines, and the introduction of particle filters would have a considerable impact on particle emissions. Vehicle emissions regulation is controlled by the EU. The coming emission regulation, EURO 5, is expected to be put into effect by the beginning of 2010. The current suggestions for the EURO 5 restrictions on particles are set so strict that they will be impossible to fulfil without a particle filter. This report performs a socio-economic analysis on the introduction of particle filters on all light vehicles (<3,500 kg). The analysis assumes that all newly registered diesel powered cars and vans should have a factory installed particle filter from the beginning of 2007. This thereby gives a period of three years before implementation of the EURO 5. (au)

    With the aim to supply the energy-intense and highly industrialized economy of the Federal Republic of Germany more climate-friendly and crisis-safely with a larger contribution of homelike energy in the past years by the federal government a manifold of obligatory aims were composed. So for instance the greenhouse-gas emissions of 1990 shall be reduced against 2020 by 40 %. This shall be reached among others by an increased use of the renewable energies. But a transformation of these ambitionized aims seems from the present view only realistic, if in future all in Germany available options for the supply of current and heat from renewable energies are distinctly more intensively used. In front of the background of the geothermic potentials available in Germany the current and heat supply from deep geothermics is a very much promising option. But in 2012 only one facility and in 2013 three facilities have gone to the net. But against this a far-reaching usage of the geothermics in the context of the energy transition and the large heat and current production potentials in Germany is worth to be aspired. In front of the described problematics the aim of this work is to show how the system technics of the facilities for the usage of the deep underground for a current respectively heat production present themselves and how such complete facilities can be evaluated by means of technical, economical, and ecological characteristics. Base on the shown political aim settings it then shall be analyzed, how the calculated characteristics could change in future and whether the deep geothermics can provide an increasing contribution in the energy system of the future. The corresponding potential further developments are thereby analyzed regarding a short-termed (i. e. 2020) and an intermediate-termed (i. e. 2030) time horizon.

    Agrarian rural dwellers in Nigeria produce about 95% of locally grown food commodities. The low accessibility to and affordability of orthodox medicine by rural dwellers and their need to keep healthy to be economically productive, have led to their dependence on traditional medicine. This paper posits an increasing acceptance of traditional medicine country-wide and advanced reasons for this trend. The fact that traditional medicine practitioners' concept of disease is on a wider plane vis-à-vis orthodox medicine practitioners' has culminated in some socio-cultural and magico-religious practices observed in preparation and use of plant medicines for farmers' health management. Possible scientific reasons were advanced for some of these practices to show the nexus between traditional medicine and orthodox medicine. The paper concludes that the psychological aspect of traditional medicine are reflected in its socio-cultural and magico-religious practices and suggests that government should fund research into traditional medicine to identify components of it that can be integrated into the national health system.

    Full Text Available INTRODUCTION: Cost effectiveness analyses (CEA can provide useful information on how to invest limited funds, however they are less useful if different analysis of the same intervention provide unclear or contradictory results. The objective of our study was to conduct a systematic review of methodologic aspects of CEA that evaluate Interferon Gamma Release Assays (IGRA for the detection of Latent Tuberculosis Infection (LTBI, in order to understand how differences affect study results. METHODS: A systematic review of studies was conducted with particular focus on study quality and the variability in inputs used in models used to assess cost-effectiveness. A common decision analysis model of the IGRA versus Tuberculin Skin Test (TST screening strategy was developed and used to quantify the impact on predicted results of observed differences of model inputs taken from the studies identified. RESULTS: Thirteen studies were ultimately included in the review. Several specific methodologic issues were identified across studies, including how study inputs were selected, inconsistencies in the costing approach, the utility of the QALY (Quality Adjusted Life Year as the effectiveness outcome, and how authors choose to present and interpret study results. When the IGRA versus TST test strategies were compared using our common decision analysis model predicted effectiveness largely overlapped. IMPLICATIONS: Many methodologic issues that contribute to inconsistent results and reduced study quality were identified in studies that assessed the cost-effectiveness of the IGRA test. More specific and relevant guidelines are needed in order to help authors standardize modelling approaches, inputs, assumptions and how results are presented and interpreted.

    We report results from analyses performed for the Ministry of Finance and the Ministry of the Environment of specified climate policy scenarios. The results are computed by means of the model MSG-TECH, which is a computable general equilibrium model that allows for technological abatement options. All the scenarios model the participation in EU emissions trading scheme (ETS), which implies obligations of the firms to mitigate or purchase allowances. The scenarios also include the Kyoto commitments and the Norwegian government's pledges in the wake of the Copenhagen negotiations 2010 to reduce domestic emissions by 30 per cent and 100 per cent by 2020 and 2050, respectively. These ambitions can be met by exploiting international green mechanisms like CDM project funding. The studied scenarios differ in their assumptions about domestic emission prices. None of the scenarios obtain the ambitions set by the Parliament's Climate Agreement in 2008, corresponding to reductions of between 12 and 14 million tons from the reference in 2020. The most ambitious regime in this analysis results in a cut of 4.3 million tons CO{sub 2} equivalents in 2020, while the least ambitious obtains 1.6 million abated tons. In 2050 the cuts constitute between 5.8 and 8.9 million tons CO{sub 2} equivalents. The scenarios P10 and P20 assume a uniform carbon price of all Kyoto gas emissions (except emissions from agriculture). In the former, the uniform price corresponds to the estimated global marginal costs of avoiding a temperature increase above two degrees C. It is operationalised to 280 Nok in 2020 and 1020 Nok in 2050, respectively (in real 2011-prices). This implies that EU ETS sources pay a tax on top of the ETS price that equalise the carbon price within the rest of the economy. This scenario results in a domestic abatement of 2.0 million tons in 2020 and 8.9 million tons in 2050. In the second scenario, the uniform carbon price is assumed to increase faster until 2020

  14. ECONOMIC IMPACT OF CULTURAL TOURISM

    Full Text Available The subject of analysis in the paper is economic impact of cultural tourism and identification of the main factors which directly affect cultural tourism revenues. Most countries do not have a statistical system of monitoring and analysing individual factors of cultural tourism such as the number of arrivals of cultural tourists and consumption of cultural tourists. Therefore, it is hard to assess the economic impact of cultural tourism. In cultural tourism, cultural assets are prepared and placed on the tourist market, i.e. cultural resources are transformed into cultural tourism products. The main objective is fulfilling tourists' needs, and achieving positive effects which includes economic effects. Identification of the economic impact of cultural tourism is important because cultural resources have an inestimable value for the local community. Tourism valorisation should be used in order to achieve the necessary maximum effects with minimum negative impacts which tourism may leave on cultural resources. The objective of the paper is to identify the economic contribution of cultural tourism in the Republic of Croatia and to propose a model of identification of economic impact of cultural tourism.

    This work contributes to the economic analysis of power market architectures. A modular framework is used to separate problems of market design in different modules. The work's goal is to study real-time market design. A two-stage market equilibrium model is used to analyse the two main real-time designs: the 'market' and the 'mechanism' (with penalty). Numerical simulations show that design applied in real-time is not neutral vis-a-vis of energy markets sequence and the competition dynamic. Designs using penalty (mechanisms) cause distortions, inefficiencies and can create barriers to entry. The size of distortions is given by the temporal position of the gate that closure the forward markets. This model has also allowed us to show the key role of real-time integration between zones and the importance of good harmonization between real-time designs of each zone. (author)

    Full Text Available Blends of high-density polyethylene (HDPE, moderate and hyper-branched LLDPEs (LLDPE and HbPE, respectively have attained widespread commercial applications, though the understanding of the mechanical and melt-flow properties of such blends has been handicapped by the absence of a consensus concerning the degrees of mixing of the components. Moreover, usually the blends are obtained by melt blending, which may not ensure the initial homogeneity of the components. In our work the mixtures were prepared by dissolving the conventional LLDPE having branching content 7.2 wt% with HbPE with comonomer content 17.8 wt% in xylene at 130 °C and stirring for 2 hours. The same procedure was applied for the blending of HDPE with HbPE. After dissolving the mixtures were cooled in liquid nitrogen and after that freeze dried in vacuum line. The ratio of components in the blends was varied. Differential scanning calorimetry has been used to investigate the miscibility and thermal behavior of the blends. For this purpose isothermal and non-isothermal treatment of prepared blends were conducted. By preliminary study the double melting peaks in non-isothermal endotherms have been observed in all the studied blends. The presence of two peaks in DSC scan can be attributed to the formation of separated crystals from both the high density/linear low density and highly branched components. However, certain limited degree of co-crystallization is detected in all the LLDPE/HbPE blends and HDPE/HbPE blend rich in HbPE component.http://dx.doi.org/10.5755/j01.ms.17.3.589

    several years, IPEN/CNEN-SP has been working in the separation of the Rare Earth (RE) elements. A simple and economic procedure for the purification of technical grade cerium concentrate is described. The highly pure cerium dioxide is designed to be used as spectrochemical standard. It is obtained by association of the fractional precipitation technique, in the system RECl{sub 3}/NH{sub 4}OH/ Air/H{sub 2}O{sub 2}, to enrich the cerium up to 90% and then it is upgraded by ion exchange technique to 99.99% CeO{sub 2}. The quality control warranty was accomplished by inductively coupled mass spectrometry (ICP-MS) and neutron activation analysis. The collected values for the accompanying Rare Earth elements in a CeO{sub 2} sample are the following (ppm): La(36), Pr(19), Nd(161), Sm(11), Eu(5.3), Gd(113), Tb(89), Dy(2), Ho(0.05), Er(1), Tm(<0.05), Yb(11), Lu(19) and Y(2.1), respectively. The purity of this cerium oxide is comparable to the international spectrographic standards. (author)

    sophistication. Essential productive factors like product design, research and develop ment, technology and marketing management and other productive knowledge generally troop around the areas of high complex production structure. In order to be easy access to these factors and makes use of the accumulation of knowledge productive stock, related enterprises in industrial chain often tend to cluster in space so as to realize the division of specialization, which can give the enterprises opportunities to fully play economies of scale and externali ty of production and operation, reduce the unit costs of business operation, especially for the enterprises who pro duce complex products. Because these firms have strong forward and backward links with other companies, special ization and division will produce the cooperative economy or scope economy, enhance the spillover effect of knowl edge and overflow effect of human canital and than promoting regional economic growth. On the basis of theoretical analysis above, combining with CobbDouglas production function of neoclassical economics and fully considering regional specialization as an intrinsic mechanism to accelerate technological ad vances and eventually affect regional economic growth. In this paper, using the production dimension fourdigit firmlevel data of over 800 Chinese industries, We firstly measure economic complexity of Chinese region and con ducts empirical analyses the mechanism between regional economic complexity and economic growth based on sim ultaneous equations model. The results show that regional specialization is the main way that economic complexity promotes regional economic growth. Besides human capital, FDI, export and transport infrastructures are directly or indirectly have a positive impact on regional economic growth and regional specialization. Under the circumstances that we add the control variables to the equation systems and deal with the variables endogeneity, the coefficients of the key economic

    Based on FACTSage® software, this paper focuses on the thermodynamic calculations of selective carbothermal reactions of vanadium-bearing titanomagnetite concentrates for preparing iron-based wear-resistant material directly from vanadium-bearing titanomagnetite concentrates. The calculations show that it was most likely to generate metallic iron, titanium carbide and vanadium carbide among all possible carbothermal reactions of vanadium-bearing titanomagnetite concentrates in a vacuum of 10 Pa. The equilibrium composition calculations indicate that Fe3O4 can be reduced to metallic iron by carbon above 400°C, FeTiO3 can be converted into TiC by carbon above 800°C and V2O5 can be converted into VC by carbon above 600°C in a vacuum of 10 Pa. The investigations demonstrated that the percentage of ferrous oxides reduced to metallic iron was about 96%, the conversion percentage of FeTiO3 into TiC was about 75% and the conversion percentage of V2O5 into VC was about 94% after the selective carbothermal reactions of vanadium-bearing titanomagnetite concentrates at 1300°C for 3 h in a vacuum of 10 Pa.

    Full Text Available It has been stated in Lithuania‘s National School Concept that the primary goal of the education of Lithuania is to secure the best possible comprehensive development of physical, psychological and spiritual human powers, to create conditions for the unfolding of the personal individuality. The subject of my teaching is economic theory. We face economic questions every day and in all areas of life. Therefore, my purpose is to acquaint college students, who do not study economics, with economic basics, to develop economic thinking and literacy. Greatest attention is paid to describe economic concepts and to use them in practice. Economics can not be learned through observing, one must work, analyse, solve practical exercises, search for correct answers. The purpose of the article is to assess the students‘ approach to the relevance of the subjects of economics. It is sought to identify the possibilities of applying new methods for teaching economic subjects and of selecting a teaching method in accordance with the students‘ level of preparation. The assessment of the research carried out enables to conclude that teaching economics forms students‘ capacities of a wide range, stimulates their self-expression, prepares young people to work in market conditions. The following methods of the research have been employed: pedagogic observation, questionnaire (survey, analysis of scientific literature and generalization.

    Two novel Schiff's bases (EB1 and L1) as new macrocyclic compounds were prepared via condensation reactions between bisaldehyde (2,2'-(ethane-1,2-diylbis(oxy))dibenzaldehyde): firstly with hydrazine carbothioamide to give (EB1), secondly with 4,6-diaminopyrimidine-2-thiol to give (L1). EB1 has a general formula C₁₈H₂₀N₆O₂S₂ of mole mass=416.520, and IUPAC name ((N,N'Z,N,N'E)-N,N'-(((ethane1,2diylbis(oxy))bis(2,1phenylene))bis(methanylylidene))bis(1hydrazinylmethanethioamide). L1 has a general formula C₂₀H₁₆N₄O₂S of mole mass=376.10; and IUPAC name 1,2-bis(2-vinylphenoxy)ethane4,6-diaminopyrimidine-2-thiol). The structures of the compounds obtained were characterized based on elemental analysis, FT-IR and (1)H NMR spectra, mass, and thermogravimetric analysis (TG, DTG). The activation thermodynamic parameters, such as, ΔE(*), ΔH(*), ΔS(*) and ΔG(*) were calculated from the TG curves using Coats-Redfern method. It is important to investigate their structures to know the active groups and weak bond responsible for their biological activities. The obtained thermal (TA) and mass (MS) practical results are confirmed by semi-empirical MO-calculation using PM3 procedure, on the neutral and positively charged forms of these novel Schiff bases. Therefore, comparison between MS and TA helps in selection of the proper pathway representing the decomposition of these compounds to give indication about their structures and consequently their biological activities. Their biological activities have been tested in vitro against Escherichia coli, Proteus vulgaris, Bacillissubtilies and Staphylococcus aurous bacteria in order to assess their antimicrobial potential.

    To support the experiments in the atmospheric fluid bed boiler (AFBB) many analyses of samples of fuel, additions and waste are needed. Therefore it was necessary to obtain experience with regard to sampling, sample preparation and analysis of these materials. For a correct interpretation of the experiments in the AFBB a knowledge of the accuracy of the results of these analyses is essential. This accuracy depends largely on the sampling method. As a guide for the methods to be used the instructions in the relevant ISO Standards have been followed usually. A description is given of the procedures for sampling and analysis as well as of the equipment used. The accuracy that can be expected for the various results of analysis has been established experimentally. It was found in general that the requirements were met.

    The energetic use of biomass experiences new attention in politics and public particularly due to high prices for fossil energy and climate protection. The German bioenergy boom is determined by political decisions. In this sense, the bioenergy markets can be characterized as 'political' markets. This is often ignored given the current euphoria over bioenergy. In the policy debate bioenergy is supported by several arguments including aspects of resources, environment, labour market, economy, technology develop, agriculture, regional and structural policy. While studies of energetic and ecological Life Cycle Assessment (LCA) of the biofuels are already present, the other political aspects are quite little investigated. Particularly against the background of an introduction of the European Agricultural Fund for Rural Development (EAFRD) and an examination of the efficiency of the promotion of biofuels, still, substantial research is needed. The goal of the work is to estimate whether biofuels allow new income possibilities and which rural areas in North Rhine-Westphalia could profit from these new prospects. A possible promotion policy for rural area is outlined which increases the income chances, and at the same time reduced negative environmental effects for the future. The work starts analysing the relevant policy framework of biofuel production in North-Rhine-Westphalia. Key question is which energy crop allows a positive income effect in which regions of North-Rhine-Westphalia. For this the procedure ''energy maize for biogas'' (rape seeds and wheat were already implemented) was integrated into the regionalised agricultural sector model RAUMIS. By the assumption of a completely elastic demand for biomass thereby the ''economic supply potential'' of the energy crops of the North-Rhine/Westphalian agriculture is illustrated under given agricultural and energy-political framework. Beside the quantitative analysis of

    Systematic reviews of economic evaluations are useful for synthesizing economic evidence about health interventions and for informing evidence-based decisions. Areas covered: As there is no detailed description of the methods for performing a systematic review of economic evidence, this paper aims to provide an overview of state-of-the-art methodology. This is laid out in a 5-step approach, as follows: step 1) initiating a systematic review; step 2) identifying (full) economic evaluations; step 3) data extraction, risk of bias and transferability assessment; step 4) reporting results; step 5) discussion and interpretation of findings. Expert commentary: The paper aims to help inexperienced reviewers and clinical practice guideline developers, but also to be a resource for experts in the field who want to check on current methodological developments.

    1999-01-01

    The control of faciparum malaria is becoming increasingly challenging in many endemic areas of the world, including Nigeria, due to the development of resistance to chloroquine and other anti-malarial drugs. Current rising health care costs demands that any preventive medicine and/or disease control program be judged according to its economic viability. As has been previously noted, any successful control of malaria will depend on socio-economic factors that influence its prevalence and management in the community. Cost-benefit or cost-effectiveness analysis of proposed and current intervention strategic are thus justified. This paper presents a review of studies involving socio-economic evaluation of the morbidity and mortality consequences of malaria. Studies involving health facility utilization profile for malaria in Nigeria and elsewhere are also reviewed. The review finds no studies evaluating or determining an appropriate economic model/framework for malaria control in Nigeria and concludes that as enormous and challenging the problem of multi-drug resistant malaria is, it can still be contained if control and management strategies are adopted based on sound and practical socio-economic judgement.

    The objective of Task 5 (Operation of Pressurized Fluidized-Bed Hydro-Retorting (PFH) on Beneficiated Shale) was to modify the PFH process to facilitate its use for fine-sized, beneficiated Eastern shales. This task was divided into 3 subtasks: Non-Reactive Testing, Reactive Testing, and Data Analysis and Correlations. The potential environment impacts of PFH processing of oil shale must be assessed throughout the development program to ensure that the appropriate technologies are in place to mitigate any adverse effects. The overall objectives of Task 6 (Environmental Data and Mitigation Analyses) were to obtain environmental data relating to PFH and shale beneficiation and to analyze the potential environmental impacts of the integrated PFH process. The task was divided into the following four subtasks. Characterization of Processed Shales (IGT), 6.2. Water Availability and Treatment Studies, 6.3. Heavy Metals Removal and 6.4. PFH Systems Analysis. The objective of Task 7 (Sample Procurement, Preparation, and Characterization) was to procure, prepare, and characterize raw and beneficiated bulk samples of Eastern oil shale for all of the experimental tasks in the program. Accomplishments for these tasks are presented.

    The report presents the methodological basis for a so-called economically well-to-wheel analysis (WtW). This can be characterized as a combined life cycle analysis (LCA) and an economic welfare cost-benefit analysis (CBA). The LCA-inspired part of the analysis includes both an energy balance and an emissions inventory. However, consistent with welfare economic reasoning, importance is put on quantifying the energy consumption and emissions by a new allocation of society's scarce resources. The pure CBA part of the WtW includes a calculation of the welfare economic benefit of these changes. The presented economic WtW method is illustrated by calculating the welfare economic implications, energy balance, and emission impacts of producing and consuming 100,000 tons of rapeseed diesel (RME) per year in Denmark.

    As a preliminary study on the effects of chemical aging of polymer materials MERL and TRI have examined two polymeric materials that are typically used for offshore umbilical applications. These two materials were Tefzel, a copolymer of ethylene and tetrafluoroethylene, and Coflon, polyvinylidene fluoride. The Coflon specimens were cut from pipe sections and exposed to H2S at various temperatures and pressures. One of these specimens was tested for methane permeation, and another for H2S permeation. The Tefzel specimens were cut from .05 mm sheet stock material and were exposed to methanol at elevated temperature and pressure. One of these specimens was exposed to methanol permeation for 2 days at 100 C and 2500 psi. An additional specimen was exposed to liquid methanol for 3 days at 150 C and 15 Bar. Virgin specimens of each material were similarly prepared and tested.

    The liberalisation of network based industries represents an economic problem, which raises on the one hand a multiplicity of theoretically unresolved questions and for which exist now on the other hand experiences in economic policy in Germany. The causes of the economic problems are not only to be found thereby in certain industry characteristics of the network based industries, but also in a missed special treatment of the network based economic sectors in the past by the economic policy. However, competition pushes in network based industries at borders, because the infrastructure necessary for the production of network based services typically represents an non-open to attack, natural monopoly in the hand of an established, vertically integrated supplier. From it extensive possibilities for the discrimination of competitors result, the competition political action need draw. It applies to analyze these in the available work and to discuss alternative solutions of the discrimination problem. (orig.)

    The work of the inter-ministerial group 'Impacts of Climate Change, Adaptation and Associated Costs for France', which met between March 2007 and October 2009, led to a sector-based assessment of all climate change related impacts and of associated adaptation measures. The aim was to obtain quantified elements that could underpin public policy decision-making and especially development of the National Adaptation Plan. While the sectoral analyses focused on quantifying the costs of adaptation, the approach of the 'Territories' group, co-steered by the Datar (regional development delegation) and Ademe (agency for energy management and environment), addressed the subject of interactions between players and activities, both spatial (sharing of resources between different uses, etc.) and temporal (transition from one situation to another, etc.) and the corresponding means for adjustment. It was in this context that the SOeS proposed a methodology for diagnosis of the socio-economic vulnerability of a given sub-national territory in the face of climate change. This document provides a broad-brush outline of the accompanying guidelines developed by Sogreah Consultants SAS for use by local players. A three step approach is followed to draw up the vulnerability profile of a territory: 1 - characterising the territory by the identification of the priority activities and physical features; 2 - using the analysis tools to produce a matrix of indices of vulnerability to climate change per hazard; 3 - drawing up an initial vulnerability profile by bringing together the information from the matrix and that from feedback, either by activity or group of activities, or by environment, depending on aims. The profile leads to identification of the important issues as well as allowing identification of potential impacts to be studied in more depth. Guidelines were tested in three pilot territories facing different climate change issues: Wateringues, in the Nord

    Cognitive economics is the economics of what is in people’s minds. It is a vibrant area of research (much of it within behavioural economics, labour economics and the economics of education) that brings into play novel types of data, especially novel types of survey data. Such data highlight the importance of heterogeneity across individuals and highlight thorny issues for welfare economics. A key theme of cognitive economics is finite cognition (often misleadingly called “bounded rationality”), which poses theoretical challenges that call for versatile approaches. Cognitive economics brings a rich toolbox to the task of understanding a complex world. PMID:28149186

    Reviewed in this statement are methods of preparing solutions to be used in laboratory experiments to examine technical issues related to the safe disposal of nuclear waste from power generation. Each approach currently used to prepare solutions has advantages and any one approach may be preferred over the others in particular situations, depending upon the goals of the experimental program. These advantages are highlighted herein for three approaches to solution preparation that are currently used most in studies of nuclear waste disposal. Discussion of the disadvantages of each approach is presented to help a user select a preparation method for his particular studies. Also presented in this statement are general observations regarding solution preparation. These observations are used as examples of the types of concerns that need to be addressed regarding solution preparation. As shown by these examples, prior to experimentation or chemical analyses, laboratory techniques based on scientific knowledge of solutions can be applied to solutions, often resulting in great improvement in the usefulness of results.

    A report is presented on the possible impact of offshore oil and gas related activities on the economic development of the Shetland Islands. It is concluded that 1) the area to the west of Shetland is likely to prove less profitable than the area to the east and that this area is unlikely to increase local employment; 2) production from existing fields which flow into Sullom Voe terminal are likely to decline though not as much as previously anticipated; 3) employment related to offshore activity will remain broadly stable but will decrease at the oil terminals by 25-50% by the end of the century; and 4) there is little likelihood of downstream processing facilities being located in the Shetland Islands.

    The major use of ANTARES is Accelerator Mass Spectrometry (AMS) with {sup 14}C being the most commonly analysed radioisotope - presently about 35 % of the available beam time on ANTARES is used for {sup 14}C measurements. The accelerator measurements are supported by, and dependent on, a strong sample preparation section. The ANTARES AMS facility supports a wide range of investigations into fields such as global climate change, ice cores, oceanography, dendrochronology, anthropology, and classical and Australian archaeology. Described here are some examples of the ways in which AMS has been applied to support research into the archaeology, prehistory and culture of this continent`s indigenous Aboriginal peoples.

A total of 75 patients with venous leg ulcers extensively covered with fibrin and necrotic tissue were randomized to a PA-containing hydrogel or an amorphous hydrogel. Wounds were treated for 14 days and costs were estimated from the German payer's perspective. Medical costs included study treatment, wound treatment supply, and labor time. The clinical benefit was expressed as the number of patients with wounds >50% covered with granulation tissue within 14 days. The incremental cost-effectiveness ratio (ICER was expressed as the additional cost spent with >50% granulation tissue per day per patient within 14 days of leg ulcer care.Results: Because of individual pricing of wound dressings in hospitals, cost data were derived from the outpatient sector. A total of 33 patients were treated using the PA-based hydrogel and 37 patients using the amorphous hydrogel. The estimated total direct costs per patient and per 14 days of therapy were €306 for both treatment groups. However, with the PA-based hydrogel, 2.5 additional days with wounds covered >50% with granulation tissues were gained within 14 days of leg ulcer care compared to the comparator. The ICER was €0 per additional day spent with >50% granulation tissue.Conclusion: Although there were a greater number of dressing changes in the PA-based hydrogel treatment, the total treatment cost for 14 days of leg ulcer care was the same for both

    Biogenic residual and waste materials are subject to fundamentally different conditions than other renewable resources. Also the purposes for their use in conversion plants are different. Whereas the use of renewable energies in energy conversions plants serves to produce power and heat, biogenic residual and waste materials are primarily focused to be disposed. Considering the sustainable philosophy ''cradle to cradle'' an additional use for these input materials is gaining interest. Energy and exergy balances show that plant and process concepts have a great influence on the energetic conversion. Especially by looking at an exergy-analysis an overall assessment is made based on the working part of the product like power or heat. If economic factors are added, local, regional, and supra-regional influences can be observed and a comprehensive overview of the optimal energetic and economic use of the input materials can be given. A decision which concept of converting biogenic residual and waste materials is to be preferred cannot be made yet. Furthermore, additional ecologic/energetic, economic, and social factors should be taken into account. These factors could be included into the exergoeconomic analysis using a scoring system with economic values.

    Full Text Available Karl Popper rightly says that “real starting point for each research is set based on assumptions of reality, not only based on the real facts”. The text below was prepared In accordance with this logic, where the Theories of International Development are treated especially focusing on International Economic Development. Therefore, theoretical reflections present assumption side, and study of many empirically measured data will correspond with real facts, because with ought these facts assumption would be useless. Technically this writing consists of two parts: in the first part are elaborated all theoretical and practical characteristics of overall international development, while in a second part as a case study will be Economic Development i Kosovo. From methodological point of view this is a comparative study and based on statistical data, while problem treating approach is critical and explanatory. As it will be understood later, development theories have been decisively influenced by economic thinking, and the focus on this dimension responds best to the nature of the term development. On the other hand the fact of unfolding economical development will reflect interference and the nature of it’s inter politics. Today economic development becomes a worldwide goal, having a considerable place in most of the literature with economic content. Also, here are presented as well examples from different practices that reflect economic development in different periods and places. Here is presented international economic development starting with a brief description of a genealogy of this development and ways of economic development back that time. It is of a special importance elaboration through theoretical approach on the creation of capital and economic development, as  mercantilist theory, classic and neo classic theory, than capitalization and Socialism-Marxism.

    The article supplements the traditional economic line of reasoning with an economic sociological account of the transition from unemployment to employment. The lack of full information is recognised by economic theory while the focus on network within the tradition of economic sociology has...... not been adopted. The article argues that the importance of network actually might be very well understood within recent economic theories that emphasise the lack of full information. The empirical evidence for the importance of network both for employed and unemployed is provided by analysing a best case...... for formal recruitment. A number of factors make it likely that the recruitment processes in Denmark are less informal and dependent on network than in most other countries. However, based on a comprehensive survey material it is shown that employers to a large extent announce vacancies through informal...

    The report examines in an integrated form, the energy, emissions and welfare economic implications of introducing Danish produced biodiesel, i.e. rapeseed diesel (RME) and the first and second generation wheat ethanol in two scenarios with low and high rate of blending with fossil fuel based automotive fuels. Within this project's, analytical framework and assumptions the welfare economic analysis shows, that it would be beneficial for society to realize the biofuel scenarios to some extent by oil prices above $ 100 a barrel, while it will cause losses by oil prices at $ 65. In all cases, the fossil fuel consumption and the emissions CO2eq emissions are reduced, the effect of which is priced and included in the welfare economic analysis. The implementation of biofuels in Denmark will be dependent on market price. As it stands now, it is not favorable in terms of biofuels. The RME is currently produced in Denmark is exported to other European countries where there are state subsidies. Subsidies would also be a significant factor in Denmark to achieve objectives for biofuel blending. (ln)

    2011-01-01

    Economic analyses are increasingly appearing in the children's environmental-health literature. In this review, an illustrative selection of articles that represent cost analyses, cost-effectiveness analyses, and cost-benefit analyses is analyzed for the relative merits of each approach. Cost analyses remain the dominant approach due to lack of available data. Cost-effectiveness and cost-benefit analyses in this area face challenges presented by estimation of costs of environmental interventions, whose costs are likely to decrease with further technological innovation. Benefits are also more difficult to quantify economically and can only be partially alleviated through willingness-to-pay approaches. Nevertheless, economic analyses in children's environmental health are highly informative and important informants to public-health and policy practice. Further attention and training in their appropriate use are needed.

    Hay, J.

    2006-09-15

    The aim of this research is to discuss the effectiveness of CLC/IOPC (Civil Liability Convention) liability regime in the field of oil pollution prevention. This study is mainly carried out from a law and economics perspective, although reference is also made to the economic analysis of international environmental agreements. The first two chapters explore the deterrent potential of the international regime in terms of oil spill prevention, from a theoretical and empirical perspective. The analysis of the effectiveness of the regime as such consists in, on the one hand, considering the ability of the international regime to compensate the entire social costs of oil spills (chapter 3) and, on the other hand, to examine the incentives given to operators in maritime oil transport to prevent accidental pollution (chapters 4 and 5). Sixth chapter considers the impacts of the voluntary nature of the international regime on its deterrent potential. The results obtained from this analysis enable to identify several mechanisms by which the deterrent effect of the existing regime could be increased. However, the overall effectiveness of the international regime appears to be limited by several factors that can not be corrected by means of a modification of the CLC and IOPC conventions. (author)

    2000-05-01

    The article presents a critical review of a study BMU commissioned from the Wuppertal Institut and the Oeko Institut about economic aspects of nuclear power plant operation. Besides the fact that the study deals with economic matters within the competency not of the Ministry for the environment but of the Ministry of Economics, it contains a few illogical arguments. The study was supposed to prove these points: (1) Nuclear power plants in Germany have paid off in less than thirty years. (2) The generating costs of nuclear power plants in some instances are above the market price of electricity. (3) During the operating life of a plant, the operators derive considerable economic benefits from the reserves for decommissioning, demolition, and waste management, which more than offset the losses incurred in electricity generation. Under item (1), the expert opinion arrives are contradictory findings: On the one hand, payoff had to be assumed within less than thirty years. On the other hand, present low electricity prices no longer permitted many nuclear power plants to be run economically. Under the heading of electricity prices, the opinion arrives at the conclusion that amost all nuclear power plants should be shut down as the spot market price of electricity was sufficient to cover all costs in hardly any nuclear power plant. Under the cost item, again pure cost considerations and financial assessments are mixed up. Under item (3), reserves, the opinion does discuss the interesting alternative of waste managements funds which, however, according to the opinion, would have to create incentives to shut down a major part of nuclear power plants right away. In summary, the opinion proves item (1), which is hardly a point of conflict, but its findings on items (2) and (3) are highly doubtful. However, this is not likely to prevent the opinion from being used in the political debate. (orig.) [German] Der Artikel setzt sich kritisch mit einer Studie auseinander, die das

    本文分析本科院校“经济法”课程教学中存在的现实困境:课程目标与教材内容的矛盾、教材内容容量与课时分配的矛盾、理论教学与案例教学的矛盾、不同教学对象与课程内容的矛盾、教师知识素质与经济法内容矛盾、课程考核方式与学习成效的矛盾。提出以经济法应用为主旨,结合教学实践,明确教学目标、教师岗位管理标准化、教材选用标准化、教学方式标准化、案例选用标准化、教学考核管理标准化等互动模式,为本科院校“经济法”课程教学中运用标准化提供参考与借鉴。%In this paper, we analyzed the practical dififculties in teaching undergraduates the course of“economic law”in colleges or universities, including the contradiction between the course objective and the teaching material, the contradiction between the capacity of teaching material and the class hour, the contradiction between theory teaching and case teaching, the contradiction between teaching objects and course contents, the contradiction between the quality of teachers' knowledge and the content course of“economic law”, the contradiction between the way for course assessment and learning results. In order to provide little hindsight in standardization of teaching“economic law”, we herein bring forward a claim that we should clear teaching goal as well as standardize the management of teaching jobs, the teaching materials, teaching methods, the case selection, and the management of teaching assessment.

    Full Text Available This study develops and tests a model that proposes economic necessity moderates the relationship between psychological contract violations (PCVs and organizational commitment and trust in the employing organization among non-unionized manufacturing workers (N = 226. Moderated regression analyses revealed that there was a significant interaction between PCV and economic necessity in predicting both outcomes. Specifically, the findings indicated that individuals experiencing high PCV and high economic necessity did not decrease their organizational commitment like their counterparts who endorsed lower economic necessity. They did, however, experience significantly decreased trust in their employer. The findings suggest that individuals who are forced to sell their labor power and obtain what they need through the market are more likely to continue to be exploited by their employer, as they have no other options than to continue the relationship. The importance of the findings is discussed, and recommendations for future research are provided.

    Is magnetic resonance imaging (MRI) based target volume definition for treatment planning of vertebral metastasis effective under economic considerations.From 1994 to 1999, a total of 137 patients with bone metastases affecting the vertebral column underwent MRI of the cercival, thoracic, or lumbar spine for the treatment planning of palliative radiation therapy. The following radiation treatment consisted in a irradiation of the affected vertebral region up to a total dose of 30-40 Gy.The cost calculation for radiotherapy and magnetic resonance tomography was done using the common tariff model (EBM) of the German Health Insurances.In 73% of patients (101 patients), magnetic resonance imaging resulted in marked corrections of the irradiation fields which would have resulted in the necessity of treatment for recurrence in the case of treatment planning without MRI.Consequently, the higher cost of MRI of 345.00 DEM (176,40 EUR) lead to a saving of 497.00 DEM (254,11 EUR) compared to a recurrence treatment of 10 fractions and of 1,428.00 DEM (730,12 EUR) compared to 20 fractions. The transport expenses for the second treatment could be saved as well.Even under economic considerations MRI is effective. (orig.)

    Zeymer, Martin [DBFZ Deutsches Biomasseforschungszentrum gemeinnuetzige GmbH, Leipzig (Germany); Meisel, Kathleen; Clemens, Andreas

    2015-07-01

    Hydrothermal Carbonisation (HTC) is an innovative process to convert biogenic residual materials from municipalities into high-quality biogenic solid fuels (charcoal). However, this entails increasing fuel costs. Especially high capital costs and a lower capacity factor of innovative processes as well as the pelletising of the charcoal are the main cost drivers. Hence an on-site utilisation of the charcoal without pelletising, e.g. for heat generation, has a high cost reduction potential. Due to the higher capital costs of solid fuel boilers and fuel storage compared to oil and gas boilers, a high degree of capacity utilisation should be pursued to reduce the fixed cost share and, by this means, lower the levelised costs of heat. Currently, the Hydrothermal Carbonisation conversion process is expensive. Therefore, using the charcoal for heat production is not competitive compared to other fossil or biofuels. The high development and cost reduction potential of this innovative process may have a positive economic impact on future utilisation.

  7. Ecological economics and economic growth.

    Science.gov (United States)

    Victor, Peter A

    2010-01-01

    Boulding's 1966 paper on the economics of spaceship Earth established the framework for ecological economics and an understanding of economic growth. In ecological economics, economies are conceptualized as open subsystems of the closed biosphere and are subject to biophysical laws and constraints. Economic growth measured as an increase in real gross domestic product (GDP) has generally been associated with increases in the use of energy and materials and the generation of wastes. Scale, composition, and technology are the proximate determinants of environmental impacts. They are often reduced to two: scale (GDP) and intensity (impact per unit GDP). New work described in this paper defines "green" growth as intensity that declines faster than scale increases. Similarly, "brown" growth occurs when intensity declines more slowly than increases in scale, and "black" growth happens when both scale and intensity increase. These concepts are then related to the environmental Kuznets curve, which can be understood as a transition from brown to green growth. Ecological economics provides a macroperspective on economic growth. It offers broad policy principles, and it challenges the primacy of economic growth as a policy objective, but many important questions remain.

HA DSC curves showed well-defined thermal events indicative of intramolecular bonds (300 ºC and intermolecular organo-mineral linkages (500 ºC. All samples showed high nitrogen contents (from peptide chains and probably N-heterocycles and aromatic and/or unsaturated aliphatic conjugated structures, as well as a low carboxylic functionality content. The SH-HA was the most similar to a medium soil HA and the RA-HA being the least similar. The results show that it is possible to prepare distinct worm-composts to solve specific problems of degraded soils.

    In federal fiscal year 2000 (FY00), Berkeley Lab had 4,347 full- and part-time employees. In addition, at any given time of the year, there were more than 1,000 Laboratory guests. These guests, who also reside locally, have an important economic impact on the nine-county Bay Area. However, Berkeley Lab's total economic impact transcends the direct effects of payroll and purchasing. The direct dollars paid to the Lab's employees in the form of wages, salaries, and benefits, and payments made to contractors for goods and services, are respent by employees and contractors again and again in the local and greater economy. Further, while Berkeley Lab has a strong reputation for basic scientific research, many of the Lab's scientific discoveries and inventions have had direct application in industry, spawning new businesses and creating new opportunities for existing firms. This analysis updates the Economic Impact Analysis done in 1996, and its purpose is to describe the economic and geographic impact of Laboratory expenditures and to provide a qualitative understanding of how Berkeley Lab impacts and supports the local community. It is intended as a guide for state, local, and national policy makers as well as local community members. Unless otherwise noted, this analysis uses data from FY00, the most recent year for which full data are available.

    Dinitz, S

    1976-01-01

    Economic crime, often also referred to as white collar crime, is one of the most incidious and predatory of offenses. Unlike street crime, for which there may well be some protection, the average citizen is completely at the mercy of the perpetrators of economic crimes. The concept of white collar crime was first identified by Edwin H. Sutherland. He dealt with the problem as a violation of trust involving either or both misrepresentation and duplicity. He argued for the use of criminal sanctions rather than civil remedies as a means of dealing with white collar offenses. Sutherland's views were attacked by the legal profession, by sociologists and criminologists and by public opinion specialists. They contended that an act treated in civil court is not a crime; that criminals are those persons who are defined as such and white collar criminals are neither so defined nor do they define themselves as criminals and, finally, that economic crime is universal. Can anyone be criminal, then, ask the critics? A number of studies by Clinard, Quinney, Black, Ball, Cressey, Newman and others have translated the interest in white collar crime into empirical terms. The last thirty-five years have also witnessed the elaboration and alteration of the theory itself. Geis' work has been particularly important in this respect. His "street" versus "suite" crime is a useful dichotomy. Most important, however, have been the monograph and papers by Herbert Edelhertz who has conceptualized the issues on various levels - from consumer fraud to the illegal activities of the multinational corporation. This article is concerned with the exposition of the theory and research in the field. Most significant, the paper raises serious doubts whether the problem of economic crime can be researched and studied; it raises even more difficult issues concerning the legal and sociological implications of economic crime and of its prevention, management and control.

    The paper analyses the periodical characteristics of the economic development of Shandong Province by using the mini-mum variation analysis model. The analysis shows that the eco-nomic development process of Shandong Province has short, medium and long cycles respectively for 6, 12, 19 years, and the fluctuation of the economic development becomes gentler with time passing by. The fluctuation of macro-control policy, invest-ment and consumption are the main reasons of the economic fluc-tuation.

  17. Analyses and economic potential of monazite in Liberia

    Science.gov (United States)

    Rosenblum, Sam

    1974-01-01

    Eleven monazite samples from Liberia, including seven from beach sands, were analyzed by the X-ray fluorescence method. The monazite samples, containing only one-half percent impurities, were obtained by use of a hot Clerici-solution procedure for purification which was devised by the author. The percentage of the rare-earth elements in Liberian monazite concentrates does not differ greatly from that of monazite sands elsewhere in the world. The average of the 11 samples shows less praseodymium and neodymium than Russian and American monazites, but more cerium. Liberian coastal sands apparently contain sufficient reserves of monazite (and other heavy minerals of commerce) to encourage mining. A feasibility study of production and marketing of monazite from Liberian beach sands is recommended.

    The Energy Policy and Conservation Act (EPCA) mandated that minimum energy efficiency standards be established for classes of refrigerators and refrigerator-freezers, freezers, clothes dryers, water heaters, room air conditioners, home heating equipment, kitchen ranges and ovens, central air conditioners, and furnaces. EPCA requires that standards be designed to achieve the maximum improvement in energy efficiency that is technologically feasible and economically justified. Following the introductory chapter, Chapter Two describes the methodology used in the economic analysis and its relationship to legislative criteria for consumer product efficiency assessment; details how the CPES Value Model systematically compared and evaluated the economic impacts of regulation on the consumer, manufacturer and Nation. Chapter Three briefly displays the results of the analysis and lists the proposed performance standards by product class. Chapter Four describes the reasons for developing a baseline forecast, characterizes the baseline scenario from which regulatory impacts were calculated and summarizes the primary models, data sources and assumptions used in the baseline formulations. Chapter Five summarizes the methodology used to calculate regulatory impacts; describes the impacts of energy performance standards relative to the baseline discussed in Chapter Four. Also discussed are regional standards and other program alternatives to performance standards. Chapter Six describes the procedure for balancing consumer, manufacturer, and national impacts to select standard levels. Details of models and data bases used in the analysis are included in Appendices A through K.

    Attanasi, E.D.; Freeman, P.A.

    2009-01-01

    The U.S. Geological Survey (USGS) has published assessments by geologists of undiscovered conventional oil and gas accumulations in the North Slope of Alaska; these assessments contain a set of scientifically based estimates of undiscovered, technically recoverable quantities of oil and gas in discrete oil and gas accumulations that can be produced with conventional recovery technology. The assessments do not incorporate economic factors such as recovery costs and product prices. The assessors considered undiscovered conventional oil and gas resources in four areas of the North Slope: (1) the central North Slope, (2) the National Petroleum Reserve in Alaska (NPRA), (3) the 1002 Area of the Arctic National Wildlife Refuge (ANWR), and (4) the area west of the NPRA, called in this report the 'western North Slope'. These analyses were prepared at different times with various minimum assessed oil and gas accumulation sizes and with slightly different assumptions. Results of these past studies were recently supplemented with information by the assessment geologists that allowed adjustments for uniform minimum assessed accumulation sizes and a consistent set of assumptions. The effort permitted the statistical aggregation of the assessments of the four areas composing the study area. This economic analysis is based on undiscovered assessed accumulation distributions represented by the four-area aggregation and incorporates updates of costs and technological and fiscal assumptions used in the initial economic analysis that accompanied the geologic assessment of each study area.

    This report provides the results of a study of methods of economic analysis applied to the evaluation of fusion research. The study recognizes that a hierarchy of economic analyses of research programs exists: standard benefit-cost analysis, expected value of R and D information, and expected utility analysis. It is shown that standard benefit-cost analysis, as commonly applied to research programs, is inadequate for the evaluation of a high technology research effort such as fusion research. A methodology for performing an expected value analysis is developed and demonstrated and an overview of an approach to perform an expected utility analysis of fusion research is presented. In addition, a potential benefit of fusion research, not previously identified, is discussed and rough estimates of its magnitude are presented. This benefit deals with the effect of a fusion research program on optimal fossil fuel consumption patterns. The results of this study indicate that it is both appropriate and possible to perform an expected value analysis of fusion research in order to assess the economics of a fusion research program. The results indicate further that the major area of benefits of fusion research is likely due to the impact of a fusion research program on optimal fossil fuel consumption patterns and it is recommended that this benefit be included in future assessments of fusion research economics.

Large-scale economic developments, such as sports and entertainment arenas and casinos, may improve the living conditions, economics, public health, and overall wellbeing of area residents and may influence rates of violence within communities. Objective. To assess the effect of community economic development efforts on neighborhood residents’ perceptions on violence, safety, and economic benefits. Methods. Telephone survey in 2011 using a listed sample of randomly selected numbers in six Pittsburgh neighborhoods. Descriptive analyses examined measures of perceived violence and safety and economic benefit. Responses were compared across neighborhoods using chi-square tests for multiple comparisons. Survey results were compared to census and police data. Results. Residents in neighborhoods with the large-scale economic developments reported more casino-specific and arena-specific economic benefits. However, 42% of participants in the neighborhood with the entertainment arena felt there was an increase in crime, and 29% of respondents from the neighborhood with the casino felt there was an increase. In contrast, crime decreased in both neighborhoods. Conclusions. Large-scale economic developments have a direct influence on the perception of violence, despite actual violence rates.

As of yet, with only a few exceptions, this subject has not appeared in the study programs of Czech universities. This subject is taught at Czech universities in various specific forms only on selected faculties - VŠE Praha, UK in Praha, MU in Brno and UP in Olomouc. OBJECTIVES: The aim of this paper is to describe a new subject, its design, targeting and content. The secondary objective is to highlight the factual reasons for its creation as an immediate response to the many unresolved questions and problems arising from the interdisciplinary relationship between kinanthropology (in the strict sense of the word "movement", and economics considering theoretical and practical aspects of evaluating the cost-effectiveness of sports activities, grant programs, the effectiveness of the grant process, the effectiveness of sports projects etc. METHODS: The proposal for the course "Economics of Sport" methodically builds on the division of kinanthropology into subspecialties, specifically the subfield of "economic kinanthropology" (Hodaň, 2006. The syllabus of the course is based on an analysis of domestic and foreign literature, analysis of the Czech environment, analyzing primary and secondary data from the sports environment of the country - region - municipality (towns, villages - sports movements (sport associations and clubs, including analysis of sports bodies and the business environment of sports. RESULTS: The course syllabus prepared is focused on the following priority areas: micro-economic aspects of sport, macro-economic aspects of sport, public economics in sports, the interdisciplinary model of the productive aspect of

    2012-10-01

    Full Text Available The paper deals with failures of capitalism or free market and presents the results of economic analysis by applying a logistic capital growth model. The application of a logistic growth model for analysis of economic bubbles reveals the fundamental causes of bubble formation—economic paradoxes related with phenomena of saturated markets: the paradox of growing returnability and the paradoxes of debt and leverage trap. These paradoxes occur exclusively in the saturated markets and cause the majority of economic problems of recent days including overproduction, economic bubbles and cyclic economic development. Unfortunately, these paradoxes have not been taken into account when dealing with the current failures of capitalism. The aim of the paper is to apply logistic capital growth models for the analysis of economic paradoxes having direct impact on the capitalism failures such as economic bubbles, economic crisis and unstable economic growth. The analysis of economic paradoxes and their implication son failures of capitalism provided in the paper presents the new approach in developing policies aimed at increasing economic growth stability and overcoming failures of capitalism.

    Full Text Available Are economic freedoms going to clear our way to prosperity? Is the growth of economic freedoms our path to prosperity? Is it in the base of the new understanding of development? If yes, what will necessarily have to be changed in the economic practice of every country and whole world in general? What will be changed in economic theory? What are potential consequences of an attempt to offer resistance to the new concept of development? These are just some of the questions discussed in this paper, whereas the starting point is the economy and economic development of Montenegro.

    knowledge. Differences between cost measurement for accountants and economists are considered in this paper. One of the main issues is to analyse the principal implications of the use of cost concepts in Economic Theory and in Accounting Theory; it seems that there is no clear reason why firms usually do not use an economic valuation approach in their reports. A question concerning the foundations present in economic models for value attribution seems to be a result of no identity between economic events and the organizational reality of firms. There are divergences in the practical aspects of cost and the theory surrounding the reason of its use. One of the major findings of this paper is that the way economists and accountants see cost concepts is responsible for the non win-win in usage; it looks like a hidden pragmatism in the way someone has a look on the concept. Some authors in accounting academia have tried reconciliation. The use of the concept Fair Value present in IFRS is the most recent tentative. It will be presented in the last part of this paper. With the numerous changes occurring in organizational and managerial aspects on valuation, efficiency and affectivity turn on as important subjects for business control. The growth of decision making based on good firm accounting information is the key for success in management accounting.

  20. Possible future HERA analyses

    2015-01-01

    A variety of possible future analyses of HERA data in the context of the HERA data preservation programme is collected, motivated, and commented. The focus is placed on possible future analyses of the existing $ep$ collider data and their physics scope. Comparisons to the original scope of the HERA programme are made, and cross references to topics also covered by other participants of the workshop are given. This includes topics on QCD, proton structure, diffraction, jets, hadronic final states, heavy flavours, electroweak physics, and the application of related theory and phenomenology topics like NNLO QCD calculations, low-x related models, nonperturbative QCD aspects, and electroweak radiative corrections. Synergies with other collider programmes are also addressed. In summary, the range of physics topics which can still be uniquely covered using the existing data is very broad and of considerable physics interest, often matching the interest of results from colliders currently in operation. Due to well-e...

Due to well-established data and MC sets, calibrations, and analysis procedures the manpower and expertise needed for a particular analysis is often very much smaller than that needed for an ongoing experiment. Since centrally funded manpower to carry out such analyses is not available any longer, this contribution not only targets experienced self-funded experimentalists, but also theorists and master-level students who might wish to carry out such an analysis.

Aim: our aim was to investigate the economic consequence of high dose of atorvastatin vs usual-dose of simvastatin in reducing major coronary events in patients with a history of acute myocardial infarction (AMI. Methods: the analysis is based on clinical outcome data from the IDEAL study. We conducted a cost-effectiveness analysis, comparing high dose of atorvastatin (80 mg/die versus usual-dose of simvastatin (20 mg/die in the perspective of the Italian National Health Service. We identified and quantified medical costs: drug costs according to the Italian National Therapeutic Formulary and hospitalizations were quantified based on the Italian National Health Service tariffs (2008. Effects were measured in terms of morbidity reduction (frequency of hospitalizations. We considered an observation period of 4.8 years. The costs borne after the first 12 months were discounted using an annual rate of 3%. We conducted one and multi-way sensitivity analyses on unit cost and effectiveness. Results: the cost of atorvastatin therapy over the 4.8 years period amounted to approximately 2.4 millions euro per 1,000 patients. The total cost of atorvastatin high dose was about 3.9 millions euro, the incremental cost per patient free from event is 31.176,03 euro. Discussion: this evaluation found that atorvastatin therapy is cost-effective. Results were sensitive to either clinical or economic variables.

  20. Essays in energy economics

    Energy Technology Data Exchange (ETDEWEB)

    Malischek, Raimund

    2016-10-25

    This thesis presents four essays in energy economics. The first essay investigates one of the workhorse models of resource economics, the Hotelling model of an inter-temporally optimizing resource extracting firm. The Hotelling model provides a convincing theory of fundamental concepts like resource scarcity, but very few empirical validations of the model have been conducted. This essay attempts to empirically validate the Hotelling model by first expanding it to include exploration activity and market power and then using a newly constructed data set for the uranium mining industry to test whether a major resource extracting mining firm in the industry is following the theory's predictions. The results show that the theory is rejected in all considered settings. The second and third essays investigate the difference in market outcomes under spot-market based trade as compared to long-term contract based trade in oligopolistic markets with investments. The second essay investigates analytically the difference in market outcomes in an electricity market setting, showing that investments and consumer welfare may be higher under spot-market based trade than under long-term contracts. The third essay proposes techniques to solve large-scale models of this kind, empirically, by exploring the practicability of this approach in an application to the international metallurgical coal market. The final essay investigates the influence of policy uncertainty on investment decisions. With France debating the role of nuclear technology, this essay analyses how policy uncertainty regarding nuclear power in France may feature in the French and European power sector. Applying a stochastic model for the European power system, the analysis shows that the costs of uncertainty in this particular application are rather low compared to the overall costs of a nuclear phase-out.

    Glickman, Matthew R.; Tang, Akaysha (University of New Mexico, Albuquerque, NM)

    2009-02-01

    The motivating vision behind Sandia's MENTOR/PAL LDRD project has been that of systems which use real-time psychophysiological data to support and enhance human performance, both individually and of groups. Relevant and significant psychophysiological data being a necessary prerequisite to such systems, this LDRD has focused on identifying and refining such signals. The project has focused in particular on EEG (electroencephalogram) data as a promising candidate signal because it (potentially) provides a broad window on brain activity with relatively low cost and logistical constraints. We report here on two analyses performed on EEG data collected in this project using the SOBI (Second Order Blind Identification) algorithm to identify two independent sources of brain activity: one in the frontal lobe and one in the occipital. The first study looks at directional influences between the two components, while the second study looks at inferring gender based upon the frontal component.

  6. Network class superposition analyses.

    Directory of Open Access Journals (Sweden)

    Carl A B Pearson

    Full Text Available Networks are often used to understand a whole system by modeling the interactions among its pieces. Examples include biomolecules in a cell interacting to provide some primary function, or species in an environment forming a stable community. However, these interactions are often unknown; instead, the pieces' dynamic states are known, and network structure must be inferred. Because observed function may be explained by many different networks (e.g., ≈ 10(30 for the yeast cell cycle process, considering dynamics beyond this primary function means picking a single network or suitable sample: measuring over all networks exhibiting the primary function is computationally infeasible. We circumvent that obstacle by calculating the network class ensemble. We represent the ensemble by a stochastic matrix T, which is a transition-by-transition superposition of the system dynamics for each member of the class. We present concrete results for T derived from boolean time series dynamics on networks obeying the Strong Inhibition rule, by applying T to several traditional questions about network dynamics. We show that the distribution of the number of point attractors can be accurately estimated with T. We show how to generate Derrida plots based on T. We show that T-based Shannon entropy outperforms other methods at selecting experiments to further narrow the network structure. We also outline an experimental test of predictions based on T. We motivate all of these results in terms of a popular molecular biology boolean network model for the yeast cell cycle, but the methods and analyses we introduce are general. We conclude with open questions for T, for example, application to other models, computational considerations when scaling up to larger systems, and other potential analyses.

  7. Economic Agents, Ethics and International Economic Organisations

    Directory of Open Access Journals (Sweden)

    Bruno S. Sergi

    2006-03-01

    Full Text Available The last sixty years have seen international economic organisations maintain a position at the forefront of promoting economic growth and socioeconomic development. These organisations have not achieved as much against certain benchmarks, and several observers have accused them of being unqualified to meet the needs of the poor, and even found them guilty of something worse, such as famine and disease. Although these organisations have organisational behaviour and skills, many of their funded projects lack forcefulness to such an extent that they should only be answerable through achieving certain economic facts by way of ethics and morals. We design ethics and morals as two interconnected concepts, and the rationale that binds all economic agents to their respective obligations must be interpreted by effective courses of action dictated by economic realities.

    Postmus, Judy L; Plummer, Sara-Beth; Stylianou, Amanda M

    2016-05-01

    Recent attention has been given by researchers to understanding how abusers use economic abuse strategies. Unfortunately, limited measures are available to accurately understand the prevalence of economic abuse in the lives of survivors. Recently, researchers created the 28-item Scale of Economic Abuse (SEA) but further validation is needed. This article describes the psychometric evaluation of the SEA through confirmatory and exploratory factor analyses using data collected with 120 survivors of abuse. The findings provide evidence for the reliability and validity of the SEA-12 as a shorter instrument to measure economic abuse as a distinct form of abuse.

    1996-10-01

    A 17-year-old female was in the final stage in treatment of right unilateral cleft lip and palate. She had undergone a number of previous surgeries. Hearing and speech were good on evaluation, and her social and family situation were deemed excellent. After preparatory orthodontics she underwent a Lefort I maxillary advancement. Surgery was successful and she was admitted into postoperative recovery. However, the lack of adequate preoperative preparation caused traumatic reaction from the patient and her parents: anxiety over appearance, crying, refusal of oral fluids and oral care, refusal of analgesia, and refusal to mobilize. The patience and persistence of hospital staff slowly overcame all adversities and the patient moved on to full and successful recovery, but this case prompted changes in preoperative procedures and involvement of patients and their families in postoperative meal selection, planing, and preparation.

  13. ECONOMIC GROWTH THEORIES, CONCEPTUAL ELEMENTS, CHARACTERISTICS

    Directory of Open Access Journals (Sweden)

    Florina, POPA

    2014-11-01

    Full Text Available The approach of economic growth involves understanding the concept and growth factors, respectively, analysing the growth theories, their trend in the context of the development of economic and social life. The economic growth signifies a process aimed at increasing activities in the national economy, expressed by macroeconomic indicators, respectively, the dynamics of the overall Gross Domestic Product or per inhabitant. It can appreciate that, in the short term, this process signifies phases of economic prosperity and on the long-term, expresses an upward trend, a consequence of the succession of increases and decreases. The study presents some elements which outlines the concept of economic growth, that is, definitions, meanings and the main characteristics of the theories of growth, as well as some of its determinant factors. Also, it gives a brief overview of the main theories of economic growth, as they have evolved over time, in line with the economic reality dynamics and the development of the instruments of economic analysis, starting from the classical theories to the new theories and models of economic growth of the modern age.

    2002-08-01

    Full Text Available This actuality article on leadership argues for the need to move towards a just economic society. The implications of different terms are considered within a conceptual framework. This framework is essential for a better understanding of economic justice in an institutional environment, where economic relationships and economic justice has come to dominate public debate. The relations between public opinion and material wealth are analysed before justice in a mixed economy receives attention. Related conditions are discussed in succession, firstly, individual freedom and the Rule of Law, and secondly, distributive justice. The article then proceeds to discuss challenges for economic leadership in South Africa, indicating trends present in both the theoretical and political leadership current in the rest of the world. Perspective is thereby given on the situation in South African democracy, where the political focus has moved from the issue of justice as freedom, to justice in the distribution of wealth and income.

    Full Text Available The research on negotiation in the last 50 years has only considered that negotiation occurs in a stable economic environment. This paper analyses negotiation in changing contexts with a focus on two aspects: first, we examine the psychological processes affecting negotiation in a changing environment, whether one of prosperity or economic crisis; second, we study collective bargaining, focusing on the role of union representatives in a context of economic crisis. The first line of research is highly experimental; the second is applied and based on field studies using interviews and focus groups.

    McCabe, C J; Akehurst, R L

    1997-02-01

    Economic evaluations of health-care technologies are playing an increasingly central role in determining which therapies are available to clinicians in the treatment of a whole range of conditions. In rheumatology, a large body of work has already been done on the cost effectiveness of alternative non-steroidal anti-inflammatory drugs (NSAIDs), and much of the current work on disease modifying therapies incorporates economic evaluations. This chapter describes the main techniques of economic evaluation and reviews the strengths and weaknesses of each. Two published economic evaluations are discussed in order to highlight what economic evaluations can offer to the care of people with rheumatoid arthritis, as well as the current limitations of economic evaluation. The objective of this chapter is to equip readers with a critical understanding of economic evaluation that can be used in considering the increasing volume of health economic data that they encounter in their clinical work.

    Understanding cities is central to addressing major global challenges from climate change to economic resilience. Although increasingly perceived as fundamental socio-economic units, the detailed fabric of urban economic activities is only recently accessible to comprehensive analyses with the availability of large datasets. Here, we study abundances of business categories across US metropolitan statistical areas, and provide a framework for measuring the intrinsic diversity of economic activities that transcends scales of the classification scheme. A universal structure common to all cities is revealed, manifesting self-similarity in internal economic structure as well as aggregated metrics (GDP, patents, crime). We present a simple mathematical derivation of the universality, and provide a model, together with its economic implications of open-ended diversity created by urbanization, for understanding the observed empirical distribution. Given the universal distribution, scaling analyses for individual business categories enable us to determine their relative abundances as a function of city size. These results shed light on the processes of economic differentiation with scale, suggesting a general structure for the growth of national economies as integrated urban systems.

    Despite indications of the problematic nature of laissez faire capitalism, such as the convictions of corporate leaders and the global financial crisis that appeared to largely stem from a de-regulated financial services industry, it seems clear that societies and environments continue to be strongly influenced by hyper-economized worldviews and practices. Given the importance of societal acceptance of a potentially dominant ideological perspective, it is logical to assume that it would be critical for students to be prepared to function in niches prioritizing unrestricted for-profit commodity exchanges. Indeed, in their article in this issue, Lyn Carter and Ranjith Dediwalage appear to support this claim in their analyses of the large-scale and expensive Australian curriculum and instruction project, Sustainability by the Bay. More specifically, they effectively demonstrate that this project manifests several characteristics that would suggest neoliberal and neoconservative influences—ideological perspectives that they argue are largely fundamental to the functioning of the global economic system. In this forum article, possible adverse effects of neoliberalism and neoconservatism on school science are discussed—with further justification for Carter and Dediwalage's concerns. Additionally, however, this article raises the possibility of subverting neoliberalism and neoconservatism in science education through application of communitarian ideals.

  9. Food preparation patterns in German family households. An econometric approach with time budget data.

    Science.gov (United States)

    Möser, Anke

    2010-08-01

    In Germany, the rising importance of out-of-home consumption, increasing usage of convenience products and decreasing knowledge of younger individuals how to prepare traditional dishes can be seen as obvious indicators for shifting patterns in food preparation. In this paper, econometric analyses are used to shed more light on the factors which may influence the time spent on food preparation in two-parent family households with children. Two time budget surveys, carried out 1991/92 and 2001/02 through the German National Statistical Office, provide the necessary data. Time budget data analyses reveal that over the last ten years the time spent on food preparation in Germany has decreased. The results point out that time resources of a household, for example gainful employment of the parents, significantly affect the amount of time spent on food preparation. The analysis confirms further that there is a more equal allocation of time spent on cooking, baking or laying the table between women and men in the last ten years. Due to changing attitudes and conceivably adaption of economic conditions, differences in time devoted to food preparation seem to have vanished between Eastern and Western Germany. Greater time spent on eating out in Germany as well as decreasing time spent on food preparation at home reveal that the food provisioning of families is no longer a primarily private task of the households themselves but needs more public attention and institutional offers and help. Among other points, the possibility of addressing mothers' lack of time as well as growing "food illiteracy" of children and young adults are discussed.

    遗传资源是农业生产中重要的投入要素,通过将遗传资源投入纳入C-D生产函数模型,并对2001—2007年江苏省农业生产经济数据进行分析,计算江苏省遗传资源及其他生产要素对农业经济增长的贡献率。结果表明,江苏省农业经济增长主要依赖于动物遗传资源投入和科技进步。与固定资产和劳动力投入要素相比,遗传资源对农业经济增长的整体贡献明显,其中动物遗传资源的贡献高于植物遗传资源。因此,江苏省应优化农业结构,提高遗传资源利用率,加大科技投入,推进农业现代化建设。%Genetic resource is an important input factor in agricultural production. Usually contributions of production fac⁃tors such as labor, fixed assets and technology to agricultural economic growth were calculated using the C⁃D production function model. While in this study, the concept of genetic resources was firstly introduced into the model to evaluate con⁃tributions of the factors to agricultural economic growth. For that end, Jiangsu Province was cited as a case for study. Cal⁃culation of contributions of genetic resources and other production factors to agricultural economic growth was done based on the data of agricultural production in Jiangsu Province from 2001 to 2007. Results show that agricultural economic growth in Jiangsu Province depends mainly on input of animal genetic resources and technological innovation. Although the contribution of technological innovation to agricultural economic growth in Jiangsu Province is high, while that of genetic resources is also significant. Meanwhile, the contribution of animal genetic resources is larger than that of plant genetic re⁃sources. Therefore, Jiangsu Province should optimize its agricultural structure, improve its utilization of genetic resources, and increase its sci⁃tech input so as to promote the construction of its modern agriculture.

    Directory of Open Access Journals (Sweden)

    2007-02-01

    Full Text Available A microeconomic, agent based framework to dynamic economics is formulated in a materialist approach. An axiomatic foundation of a non-equilibrium microeconomics is outlined. Economic activity is modelled as transformation and transport of commodities (materials owned by the agents. Rate of transformations (production intensity, and the rate of transport (trade are defined by the agents. Economic decision rules are derived from the observed economic behaviour. The non-linear equations are solved numerically for a model economy. Numerical solutions for simple model economies suggest that the some of the results of general equilibrium economics are consequences only of the equilibrium hypothesis. We show that perfect competition of selfish agents does not guarantee the stability of economic equilibrium, but cooperativity is needed, too.

  18. Economic uncertainty and econophysics

    Science.gov (United States)

    Schinckus, Christophe

    2009-10-01

    The objective of this paper is to provide a methodological link between econophysics and economics. I will study a key notion of both fields: uncertainty and the ways of thinking about it developed by the two disciplines. After having presented the main economic theories of uncertainty (provided by Knight, Keynes and Hayek), I show how this notion is paradoxically excluded from the economic field. In economics, uncertainty is totally reduced by an a priori Gaussian framework-in contrast to econophysics, which does not use a priori models because it works directly on data. Uncertainty is then not shaped by a specific model, and is partially and temporally reduced as models improve. This way of thinking about uncertainty has echoes in the economic literature. By presenting econophysics as a Knightian method, and a complementary approach to a Hayekian framework, this paper shows that econophysics can be methodologically justified from an economic point of view.

    Economic geography has over the last decade become increasingly interested in the role of practice, conceptualised as the regularised or stabilised social actions through which economic agents organize or coordinate production, marketing, service provision, exchange and/or innovation activities. Interest in practice is most clearly manifest in a growing body of research concerned to conceptualise how the regularized social relations and interactions linking economic actors (e.g. entrepreneurs...

    This paper explains some plain phenomena in teaching and class management with an economic view. Some basic economic principles mentioned therein are: everything has its opportunity cost; the marginal utility of consumption of any kind is diminishing; Game theory is everywhere. By applying the economic theories to teaching, it is of great help for teachers to understand the students' behavior and thus improve the teaching effectiveness and efficiency.

    OpenAIRE

    1998-01-01

    This paper reviews economic developments in Turkmenistan during 1994–97. To address the growing economic difficulties, the government announced an economic reform package for 1996, which aimed at achieving a recovery in output, sharply lowering inflation, maintaining a strong reserve position, and promoting private sector development. The reform package had mixed success. Monetary and credit policy was generally restrained until late 1996, contributing to a moderation in inflation. However,...

  8. Economic, Political and Communicative power in the neoliberal societies

    Directory of Open Access Journals (Sweden)

    Laura Bergés-Saura, Ph. D.

    2010-01-01

    Full Text Available The article analyses the relations between the economic, political and communicative powers in the socioeconomic model of neoliberal capitalism. Firstly, it examines the transformations in the economic power, to analyse later the various mechanisms linking this changing economic power to the media performance. Among these mechanisms, the article analyses the control of ownership and other external financial sources; the origin of commercial income; and business management techniques, while simultaneously investigating the relations between these variables and the transformations in the economic sphere. Following the political economy tradition, the article addresses the implications that the concentration of economic, political and communicative power have on democracy and freedom, taking into account the evolution of the socioeconomic and political system in the last decades.

  9. Maximization, learning, and economic behavior.

    2014-07-22

    The rationality assumption that underlies mainstream economic theory has proved to be a useful approximation, despite the fact that systematic violations to its predictions can be found. That is, the assumption of rational behavior is useful in understanding the ways in which many successful economic institutions function, although it is also true that actual human behavior falls systematically short of perfect rationality. We consider a possible explanation of this apparent inconsistency, suggesting that mechanisms that rest on the rationality assumption are likely to be successful when they create an environment in which the behavior they try to facilitate leads to the best payoff for all agents on average, and most of the time. Review of basic learning research suggests that, under these conditions, people quickly learn to maximize expected return. This review also shows that there are many situations in which experience does not increase maximization. In many cases, experience leads people to underweight rare events. In addition, the current paper suggests that it is convenient to distinguish between two behavioral approaches to improve economic analyses. The first, and more conventional approach among behavioral economists and psychologists interested in judgment and decision making, highlights violations of the rational model and proposes descriptive models that capture these violations. The second approach studies human learning to clarify the conditions under which people quickly learn to maximize expected return. The current review highlights one set of conditions of this type and shows how the understanding of these conditions can facilitate market design.

  10. ECONOMIC CHALLENGES FOR EUROPEAN DEFENCE

    2016-12-01

    Full Text Available The issue of a common European Union (EU defence is on the frontline of political and media discussions, in light of the recent evolutions in the security and defence environment. The main challenge in this respect is related to the realism and feasibility of moving beyond political declarations towards a more concrete implementation of a common defence policy, considering the numerous political, military and economic factors involved. The aim of this paper is to analyse the challenges faced by the concept of a common European defence from an economic point of view, considering the evolution of the defence expenditures in the EU member states, compared to the wider European and the global trend. Also, the paper will focus on the impact the economic crisis and the ensuing austerity measures had on the member states and on their cooperation in developing a common approach on defence, with a view on the ways ahead and recommendations on overcoming the difficult challenges in this respect.

We derive "politico-economic equivalence" conditions that apply in environments where policy is endogenous and chosen sequentially. A policy regime...... and a state are equivalent to another such pair if both pairs give rise to the same allocation in politico-economic equilibrium. The equivalence conditions help to identify factors that render institutional change non-neutral and to construct politico-economic equilibria in new policy regimes.

    Koivusalo, Meri

    2006-01-01

    The analysis of the impact of economic globalisation on health depends on how it is defined and should consider how it shapes both health and health policies. I first discuss the ways in which economic globalisation can and has been defined and then why it is important to analyse its impact both in terms of health and health policies. I then explore the ways in which economic globalisation influences health and health policies and how this relates to equity, social justice, and the role of values and social rights in societies. Finally, I argue that the process of economic globalisation provides a common challenge for all health systems across the globe and requires a broader debate on values, accountability, and policy approaches.

  2. Economic benefits of an economizer system: Energy savings and reduced sick leave

    Energy Technology Data Exchange (ETDEWEB)

    Fisk, William J.; Seppanen, Olli; Faulkner, David; Huang, Joe

    2004-02-01

    This study estimated the health, energy, and economic benefits of an economizer ventilation control system that increases outside air supply during mild weather to save energy. A model of the influence of ventilation rate on airborne transmission of respiratory illnesses was used to extend the limited data relating ventilation rate with illness and sick leave. An energy simulation model calculated ventilation rates and energy use versus time for an office building in Washington, D.C. with fixed minimum outdoor air supply rates, with and without an economizer. Sick leave rates were estimated with the disease transmission model. In the modeled 72-person office building, our analyses indicate that the economizer reduces energy costs by approximately $2000 and, in addition, reduces sick leave. The annual financial benefit of the decrease in sick leave is estimated to be between $6,000 and $16,000. This modeling suggests that economizers are much more cost effective than currently recognized.

    1995-12-01

    As required by the Romer-Twining Agreement of 1990, the US Department of Energy (DOE) has prepared this annual economic impact study for the state of Colorado. This report assesses the economic impacts related to the DOE Uranium Mill Tailings Remedial Action (UMTRA) Project in Colorado during the state fiscal year (FY) between 1 July 1994 and 30 June 1995. To estimate net economic benefit, employment, salaries and wages, and other related economic benefits are discussed, quantified, and then compared to the state`s 10 percent share of the remedial action costs. Actual data obtained from sites currently undergoing remedial action were used as the basis for analyses. If data were not available, estimates were used to derive economic indicators. This study describes the types of employment associated with the UMTRA Project and estimates of the numbers of people employed by UMTRA Project subcontractors in Colorado during state FY 1995. Employment totals are reported in estimated average annual jobs; however, the actual number of workers at the site fluctuates depending on weather and on the status of remedial action activities. In addition, the actual number of people employed on the Project during the year may be higher than the average annual employment reported due to the temporary nature of some of the jobs.

  6. Antithetic Foundations of Economics

    Marin Dinu

    2011-03-01

    Full Text Available This paper aims at decrypting the manner in which the foundations of Economics as a science and the meanings of the relevant explanatory formulas are being shaped. My analytical endeavor focuses on understanding the peculiarities of what is referred to as the object of study of the science known as Economics, an academic synthesis of concept-related breakthroughs regarding economicity. The explicit purpose of this analysis is to identify perennial benchmarks in economic cognition whereby this ensures its consistency. The implicit purpose is to shape a cognitive model in line with the specifics of the conceptual universe of Economics, as well as with the sources of the economic realities that are subject to a sui-generis relativism. The primary benefit of this endeavor consists in systemizing the conceptual prospects with an antithetic nature that allow for the explanations of the state of economic rationality and generate the understanding of what the source of economicity is and how it behaves. As such, the conclusions are marked by the stringent need of more precisely defining economic knowledge in order to match the changing nature of economic reality, as an expression that embraces the meeting point of two ontological vistas that are methodologically separated by some theories: human nature and human condition. Economics as a science thus features, apart from a conceptual substrate that needs to be spotted, an ontological background that needs to be revealed. The role played by this background appears to be most frequently ignored. The joint identification of both direct and contextual determinants for a sensitive area of humankind, i.e. the economy, is a direction to be followed by the royal path of rational knowledge.

    Highlights: • We analyse ICT equipment reuse operations of socio-economic enterprises. • Most common ICT products dealt with are computers and related equipment. • In the UK in 2010, ∼143,750 appliances were reused. • Marketing and legislative difficulties are the common hurdles to reuse activities. • Socio-economic enterprises can significantly contribute to resource efficiency. - Abstract: In Europe, socio-economic enterprises such as charities, voluntary organisations and not-for-profit companies are involved in the repair, refurbishment and reuse of various products. This paper characterises and analyses the operations of socio-economic enterprises that are involved in the reuse of Information and Communication Technology (ICT) equipment. Using findings from a survey, the paper specifically analyses the reuse activities of socio-economic enterprises in the UK from which Europe-wide conclusions are drawn. The amount of ICT products handled by the reuse organisations is quantified and potential barriers and opportunities to their operations are analysed. By-products from reuse activities are discussed and recommendations to improve reuse activities are provided. The most common ICT products dealt with by socio-economic enterprises are computers and related equipment. In the UK in 2010, an estimated 143,750 appliances were reused. However, due to limitations in data, it is difficult to compare this number to the amount of new appliances that entered the UK market or the amount of waste electrical and electronic equipment generated in the same period. Difficulties in marketing products and numerous legislative requirements are the most common barriers to reuse operations. Despite various constraints, it is clear that organisations involved in reuse of ICT could contribute significantly to resource efficiency and a circular economy. It is suggested that clustering of their operations into “reuse parks” would enhance both their profile and their

    Contrary to predictions from Expected Utility Theory and Game Theory, when making economic decisions in interpersonal situations, people take the interest of others into account and express various forms of solidarity, even in one-shot interactions with anonymous strangers. Research in other-regarding behavior is dominated by behavioral economical and evolutionary biological approaches. Psychological theory building, which addresses mental processes underlying other-regarding behavior, is rare. Based on Relational Models Theory (RMT, [1]) and Relationship Regulation Theory (RRT, [2]) it is proposed that moral motives influence individuals' decision behavior in interpersonal situations via conscious and unconscious (automatic) processes. To test our propositions we developed the 'Dyadic Solidarity Game' and its solitary equivalent, the 'Self-Insurance Game'. Four experiments, in which the moral motives "Unity" and "Proportionality" were manipulated, support the propositions made. First, it was shown that consciously activated moral motives (via framing of the overall goal of the experiment) and unconsciously activated moral motives (via subliminal priming) influence other-regarding behavior. Second, this influence was only found in interpersonal, not in solitary situations. Third, by combining the analyses of the two experimental games the extent to which participants apply the Golden Rule ("treat others how you wish to be treated") could be established. Individuals with a "Unity" motive treated others like themselves, whereas individuals with a "Proportionality" motive gave others less then they gave themselves. The four experiments not only support the assumption that morals matter in economic games, they also deliver new insights in how morals matter in economic decision making.

    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

    The health of a population is important from a public health and economic perspective as healthy individuals contribute to economic growth. Vaccination has the potential to contribute substantially to improving population health and thereby economic growth. Childhood vaccination programmes in Europe can offer protection against 15 important infectious diseases, thus preventing child fatalities and any serious temporary and permanent sequelae that can occur. Healthy children are more able to participate in education, thus preparing them to become healthy and productive adults. Vaccination programmes can also prevent infectious diseases in adolescents, thus allowing them to continue their development towards a healthy adulthood. Protecting adults against infectious diseases ensures that they can fully contribute to productivity and economic development by avoiding sick leave and lower productivity. Vaccination in older adults will contribute to the promotion of healthy ageing, enabling them to assist their familiy with, for instance, childcare, and also help them avoid functional decline and the related impacts on health and welfare expenditure. Effective vaccination programmes for all ages in Europe will thus contribute to the European Union's 2020 health and economic strategies. Indeed, beyond their impact on healthcare resources and productivity, reductions in mortality and morbidity also contribute to increased consumption and gross domestic product. Therefore, assessment of the value of vaccines and vaccination needs to consider not just the direct impact on health and healthcare but also the wider impact on economic growth, which requires a macroeconomic analysis of vaccination programmes.

  7. Behavioral Economics of Education

    During the last decade knowledge about human behavior from psychology and sociology has enhanced the field of economics of education. By now research recognizes cognitive skills (as measured by achivement tests) as equally important drivers of later economic outcomes, and skills are seen as multi......-dimensional rather than one-dimensional. Explicitly accounting for soft skills often implies departing from the standard economic model by integrating concepts studied in behavioral and experimental economics, such as self-control, willingness to compete, intrinsic motivation, and self-confidence. We review how...... approaches from behavioral economics help our understanding of the complexity of educational investments and outcomes, and we discuss what insights can be gained from such concepts in the context of education....

    "Promoting sound and rapid development of the national economy"is China’s goal for economic development in the following five years,as put forward by Hu Jintao, General Secretary of the Central Committee of the Communist Party of China(CPC), in his report to the 17th National Congress of the Party. China used to target"rapid and sound"economic growth.The fact that soundness is preferred to speed for China’s economic growth reflects an important change in the economic outlook of the CPC—China is beginning to value the quality of economic growth rather than the speed. How to attain the goal of sound and rapid development for the national economy is the subject of Hu’s eight-point proposal.

    Chadderton, Ronald A

    2015-01-01

    This textbook/course supplement stands as a unique and highly original complement to the traditional engineering economics curriculum. Its primarily narrative approach conveys the essence of an “Austrian" economic perspective on cash flow analysis and decision making in engineering, without extensive tables and graphs, and requires very little mathematics. The book’s objective is to add a new perspective to the usual study of cash flow analysis and solely econometric engineering decision making. The author draws on the methodology of the Austrian Economists—a school of economic thought that bases its study of economic phenomena on the interpretation and analysis of the purposeful actions of individuals. The book includes an array of illustrative case studies examined in detail by the author and emphasizes the importance of market processes and price signals to coordinate engineering plans. Purposeful Engineering Economics is an ideal resource for students, teaching faculty, and practicing professional ...

    Realistic estimates of economic depreciation are required for analyses of tax policy, economic growth and production, and national income and wealth. THe purpose of this paper is to examine the stability assumption underlying the econometric derivation of empirical estimates of economic depreciation for industrial machinery and and equipment. The results suggest that a reasonable stability of economic depreciation rates of decline may exist over time. Thus, the assumption of a constant rate of economic depreciation may be a reasonable approximation for further empirical economic analyses.

    This paper breaks through the old study pattern, emphasizing the important of economic analysis and put forward the analytic method. The paper compares mass customization to just-in-time, analyses the two facets which include production and distribution. The production facet is influence of the indirect cost, scale economy, experiences economy and dynamic alliance. The reduction of indirect cost is the innovation, which has special angle comparatively traditional economic analysis. There is gaming between satisfying customer special demand and deciding price. Mass customization emphasizes that customer must achieve to loyalty not only content without increasing extra service charge-faith in company and product. The paper sets forth the economics of scale economy and dynamic alliance to embody the extensive economy. In addition it is another innovation that this paper analyses the defects of mass customization to evaluate the economic risk. Through comparing the traditional production mode, demonstrating the implement feasibility in company. That is mass customization has less economic risk whether or not. So the analysis proposes the evidences of the way of enterprise production.

  16. Analysing Medieval Urban Space; a methodology

    Directory of Open Access Journals (Sweden)

    Marlous L. Craane MA

    2007-08-01

    Full Text Available This article has been written in reaction to recent developments in medieval history and archaeology, to study not only the buildings in a town but also the spaces that hold them together. It discusses a more objective and interdisciplinary approach for analysing urban morphology and use of space. It proposes a 'new' methodology by combining town plan analysis and space syntax. This methodology was trialled on the city of Utrecht in the Netherlands. By comparing the results of this 'new' methodology with the results of previous, more conventional, research, this article shows that space syntax can be applied successfully to medieval urban contexts. It does this by demonstrating a strong correlation between medieval economic spaces and the most integrated spaces, just as is found in the study of modern urban environments. It thus provides a strong basis for the use of this technique in future research of medieval urban environments.

    In this paper we consider the use of exergy in economic valuation and its correlation with money. Exergy-based determination of production expenses provides a new base for 'natural' price determination. A new macroeconomic dynamics approach based on this correlation is proposed. This method is relatively general because it is not restricted by certain assumptions used in traditional economic analysis. The exergy model of macroeconomic dynamics was tested by utilizing data from the US economy. This test, covering a period of about 25 years, confirms this approach and opens new potentials in economic analysis. (Author)

    2015-02-01

    Recent advances in the thermochemical processing of biomass have resulted in efforts to commercialize several cellulosic biofuel pathways. Until commercial-scale production is achieved, however, techno-economic analysis is a useful methodology for quantifying the economic competitiveness of these pathways with petroleum, providing one indication of their long-term feasibility under the U.S. revised Renewable Fuel Standard. This review paper covers techno-economic analyses of thermochemical cellulosic biofuel pathways in the open literature, discusses and compares their results, and recommends the adoption of additional analytical methodologies that will increase the value of future pathway analyses.

  10. Current Economic Situation in Bosnia and Herzegovina

    Directory of Open Access Journals (Sweden)

    Goran Mirascic

    2011-11-01

    Full Text Available This article provides an overview of the current economic situation in Bosnia and Herzegovina. Beginning in the second half of 2008, macroeconomic conditions in B&H began precipitating a decline in economic activity. While the global financial crisis was among the factors contributing to this decline, it was far from the only factor. Problematic macroeconomic conditions were also a result of B&H’s own structural and political problems, caused largely by the shortcomings of a political entity comprising two autonomous entities. Due to such problems, the governments of B&H turned to the International Monetary Fund for assistance. This article analyzes the effects of the first two “stand by” arrangements made between the IMF and B&H and discusses implications for further, ongoing stand by arrangements made between the IMF and B&H. This paper also examines the lack of unified economic space between The Federation of Bosnia and Herzegovina and The Republic of Srpska, which has resulted not only in ineffective monetary policy but also in different fiscal and taxation systems between the two entities. While various existing analyses claim that B&H has little hope of resolving its economic woes due to its current political and economic structure, this article offers solutions and measures that, if successfully implemented, would lead to more efficient recovery and self-sustainable economic growth.

    Science.gov (United States)

    Erdmann, G.

    2015-08-01

    The following text is an introduction into the economic theory of electricity supply and demand. The basic approach of economics has to reflect the physical peculiarities of electric power that is based on the directed movement of electrons from the minus pole to the plus pole of a voltage source. The regular grid supply of electricity is characterized by a largely constant frequency and voltage. Thus, from a physical point of view electricity is a homogeneous product. But from an economic point of view, electricity is not homogeneous. Wholesale electricity prices show significant fluctuations over time and between regions, because this product is not storable (in relevant quantities) and there may be bottlenecks in the transmission and distribution grids. The associated non-homogeneity is the starting point of the economic analysis of electricity markets.

    2014-09-29

    The use of network meta-analysis has increased dramatically in recent years. WinBUGS, a freely available Bayesian software package, has been the most widely used software package to conduct network meta-analyses. However, the learning curve for WinBUGS can be daunting, especially for new users. Furthermore, critical appraisal of network meta-analyses conducted in WinBUGS can be challenging given its limited data manipulation capabilities and the fact that generation of graphical output from network meta-analyses often relies on different software packages than the analyses themselves. We developed a freely available Microsoft-Excel-based tool called NetMetaXL, programmed in Visual Basic for Applications, which provides an interface for conducting a Bayesian network meta-analysis using WinBUGS from within Microsoft Excel. . This tool allows the user to easily prepare and enter data, set model assumptions, and run the network meta-analysis, with results being automatically displayed in an Excel spreadsheet. It also contains macros that use NetMetaXL's interface to generate evidence network diagrams, forest plots, league tables of pairwise comparisons, probability plots (rankograms), and inconsistency plots within Microsoft Excel. All figures generated are publication quality, thereby increasing the efficiency of knowledge transfer and manuscript preparation. We demonstrate the application of NetMetaXL using data from a network meta-analysis published previously which compares combined resynchronization and implantable defibrillator therapy in left ventricular dysfunction. We replicate results from the previous publication while demonstrating result summaries generated by the software. Use of the freely available NetMetaXL successfully demonstrated its ability to make running network meta-analyses more accessible to novice WinBUGS users by allowing analyses to be conducted entirely within Microsoft Excel. NetMetaXL also allows for more efficient and transparent

    The interconnected systems provide large technical and economic benefits which, evaluated and contrasted with the associated network investment cost, usually produce important net savings. There are continental electrical systems formed by many interconnected subsystems. The optimal size of an interconnection should be defined within an economic background. It is necessary to take into account the global environmental effects. The approach and results of studies carried out by Red Electrica is presented, in order to analyse both economic and environmental benefits resulting from an increase in the present Spanish interconnection capacities. From both economic and environmental points of view, the development of the interconnected systems is highly positive. (author). 4 refs.

    2013-05-15

    Financial and welfare economic analyses are conducted of 15 different biogas production scenarios that vary in terms of plant size and type of input. All considered scenarios lead to welfare economic losses. Overall welfare economic GHG reduction costs seem to increase with increasing crop/crop material share of input, and although the costs vary significantly across scenarios they are quite high for all scenarios. The financial analyses suggest that biogas production generally will be financially profitable for the agricultural sector and local CHP facilities but unprofitable for the biogas plants and the State. Seen from a policy perspective the results highlights the importance of designing regulatory instruments in a way that create incentives for private actors to engage in welfare economically desirable biogas production activities while discouraging the expansion of welfare economically undesirable activities.

    Conventional economic analyses of stringent climate change mitigation have generally concluded that economic austerity would result from carbon austerity. These analyses however rely critically on the assumption of an economic equilibrium, which dismisses established notions on behavioural heterogeneity, path dependence and technology transitions. Here we show that on the contrary, the decarbonisation of the electricity sector globally can lead to improvements in economic performance. By modelling the process of innovation-diffusion and non-equilibrium dynamics, we establish how climate policy instruments for emissions reductions alter economic activity through energy prices, government spending, enhanced investment and tax revenues. While higher electricity prices reduce income and output, this is over-compensated by enhanced employment generated by investments in new technology. We stress that the current dialogue on the impacts of climate policies must be revisited to reflect the real complex dynamics invo...

  10. Big Data and Health Economics: Strengths, Weaknesses, Opportunities and Threats.

    Science.gov (United States)

    Collins, Brendan

    2016-02-01

    'Big data' is the collective name for the increasing capacity of information systems to collect and store large volumes of data, which are often unstructured and time stamped, and to analyse these data by using regression and other statistical techniques. This is a review of the potential applications of big data and health economics, using a SWOT (strengths, weaknesses, opportunities, threats) approach. In health economics, large pseudonymized databases, such as the planned care.data programme in the UK, have the potential to increase understanding of how drugs work in the real world, taking into account adherence, co-morbidities, interactions and side effects. This 'real-world evidence' has applications in individualized medicine. More routine and larger-scale cost and outcomes data collection will make health economic analyses more disease specific and population specific but may require new skill sets. There is potential for biomonitoring and lifestyle data to inform health economic analyses and public health policy.

    The purpose of the tool is to help bring district cooling solutions into consideration by facilitating rapid technical / economic and environmental analysis of district cooling solutions - also with heat pump operation. The tool is a screening tool intended for specific cases with actual data from reality. The tool can analyze the simultaneous production of heat and cooling, and use of storage can make district cooling even more profitable. It is also possible to analyze the importance of flexible electricity and heating prices and see how they can be utilized, including the calculation of the probable prices on heating and cooling, and investments. The tool can make calculations on the following plant types: - Systems with only cooling without cold storage; - Systems with only cooling with cold storage; - Systems with cooling and heating controlled by cooling - with heat storage; - Systems with heating and cooling controlled by heating - with heating and cooling storage; - Systems with cooling and heating with optimized management - with heat storage. The tool can also be used to make general assessments, for example, to analyze the importance of flexible electricity and heating prices of typical district cooling systems, and for that matter, heat pump systems.

  13. The Nullness Analyser of julia

    Science.gov (United States)

    Spoto, Fausto

    This experimental paper describes the implementation and evaluation of a static nullness analyser for single-threaded Java and Java bytecode programs, built inside the julia tool. Nullness analysis determines, at compile-time, those program points where the null value might be dereferenced, leading to a run-time exception. In order to improve the quality of software, it is important to prove that such situation does not occur. Our analyser is based on a denotational abstract interpretation of Java bytecode through Boolean logical formulas, strengthened with a set of denotational and constraint-based supporting analyses for locally non-null fields and full arrays and collections. The complete integration of all such analyses results in a correct system of very high precision whose time of analysis remains in the order of minutes, as we show with some examples of analysis of large software.

    Full Text Available Ecological Economics studies social metabolism; that is, the material and energy flow into and out of the economy. Using the ecological economics perspective, we analyse the transformation of the economic landscape of the Santiago river basin, Mexico. We discuss why the appropriation of water resources is one of the most important drivers of North American economic integration. We argue that the theoretical model of neo-extractivism can explain the dynamics of social metabolism behind the North American Free Trade Agreement (NAFTA.

  16. View from Behavioral Economics Theory: Case of Latvian Rural Entrepreneurs

    Directory of Open Access Journals (Sweden)

    Igo Cals

    2013-11-01

    Full Text Available The theory of classical economics treats entrepreneurs as subjects who make rational economic decisions. Empirical surveys prove the fact that daily economic decisions made by a separate economic entity can be explained by concepts of behavioral economics rather than classical economics. The economic behavior of entrepreneurs happens to be based on bounded rationality instead of financial justification. The objective of an economic activity presented as economically efficient can turn out to be socially important to a specific entrepreneur and not to national economy as a whole. In the EU countries, agriculture is a subsidised industry of national economy. In this light, status consumption and purchase of positional goods should create a special interest among economists. The objective of this article is to present true reasons of economic decisions made by rural entrepreneurs and to analyse the value hierarchy of Latvian rural entrepreneurs through carrying out a field work and with the help of set of instruments developed by modern economics theory.

  17. The economics of a landing obligation

    Andersen, Peder; Ståhl, Lisa

    By 2015 The European Common Fisheries Policy Reform includes a landing obligation in some fisheries and over the next few years all EU fisheries will be facing the obligation to land all catches. In spite of that, there is a lack of theoretical as well as empirical analyses of the consequences...... in our knowledge. A comprehensive analysis of the short term economic impacts of the discard ban for the Danish fleet under various assumptions regarding costs of handling previously discarded fish, prices obtained for them, selectivity, minimum sizes, and quota utilization is presented. Among other...... things, the analysis shows that the fisheries will suffer economic losses under the landing obligation if quotas are not increased with the historical discard rate. With quota top-ups however fisheries can experience economic gains which increase with reduced minimum sizes or by increasing selectivity....

    R Alexander Bentley

    Full Text Available For the 20(th century since the Depression, we find a strong correlation between a 'literary misery index' derived from English language books and a moving average of the previous decade of the annual U.S. economic misery index, which is the sum of inflation and unemployment rates. We find a peak in the goodness of fit at 11 years for the moving average. The fit between the two misery indices holds when using different techniques to measure the literary misery index, and this fit is significantly better than other possible correlations with different emotion indices. To check the robustness of the results, we also analysed books written in German language and obtained very similar correlations with the German economic misery index. The results suggest that millions of books published every year average the authors' shared economic experiences over the past decade.

In addition a summary of an extended algorithm of nonlinear time series analysis is provided which is applied not only in economical time series but also in other physical complex systems (e.g. [22, 24]. In general, Economy is a vast and complicated set of arrangements and actions wherein agents—consumers, firms, banks, investors, government agencies—buy and sell, speculate, trade, oversee, bring products into being, offer services, invest in companies, strategize, explore, forecast, compete, learn, innovate, and adapt. As a result the economic and financial variables such as foreign exchange rates, gross domestic product, interest rates, production, stock market prices and unemployment exhibit large-amplitude and aperiodic fluctuations evident in complex systems. Thus, the Economics can be considered as spatially distributed non-equilibrium complex system, for which new theoretical concepts, such as Tsallis non extensive statistical mechanics and strange dynamics, percolation, nonGaussian, multifractal and multiscale dynamics related to fractional Langevin equations can be used for modeling and understanding of the economical complexity locally or globally.

    Friedberg, Robert D

    2016-10-01

    The behavioral health care environment in the United States is changing and many experts expect seismic shifts in access, accountability and reimbursement policies. Students in professional psychology training programs will be called upon to administer, manage, supervise and deliver clinically sound as well as cost effective services. While in general, traditional professional psychology training curricula prepare students well for clinical challenges, most students enter the profession naïve to the economic, financial and business enterprise crucibles in the behavioral health care marketplace. This article examines the problem of such naiveté and offers several recommendations for improving graduate students' economic literacy. Moreover, the article argues that increased business and economic acumen may serve to close the research-practice gap in professional psychology. The article reviews literature pertinent to training psychologists and highlights pedagogical gaps. Several recommendations for curricular development are offered. Specifically, adding courses in health care economics and basic business principles is suggested. Integrating cost-effectiveness analyses across all course content is proposed. The article also emphasizes both didactic and experiential learning opportunities. Course work should be augmented with training opportunities at the practicum, internship, and post-doctoral fellowship level.

    2010-09-15

    In an effort to develop 'sustainability economics' Baumgaertner and Quaas (2010) neglect the central concept of environmental economics-'environmental externality'. This note proposes a possible connection between the concepts of environmental externality and sustainability. In addition, attention is asked for other aspects of 'sustainability economics', namely the distinction weak/strong sustainability, spatial sustainability and sustainable trade, distinctive sustainability policy, and the ideas of early 'sustainability economists'. I argue that both sustainability and externalities reflect a systems perspective and propose that effective sustainability solutions require that more attention is given to system feedbacks, notably other-regarding preferences and social interactions, and energy and environmental rebound. The case of climate change and policy is used to illustrate particular statements. As a conclusion, a list of 20 insights and suggestions for research is offered. (author)

    Full Text Available Oceans and seas represent over 70% of the earth's surface. Furthermore, living aquatic resources can provide a significant contribution to food, energy and bio-based products. However, marine ecosystems are subject to increasing pressures and competing usages, resulting from resources over-exploitation and pollution. In order to produce efficient marine management plans, it is essential to consider the total economic value provided by the marine ecosystems. In this review, we are focusing on the Marine Framework Strategy Directive and the European Marine Spatial Planning that are established for the protection and efficient use of the marine area. We present the ecosystem services approach with regards to the marine ecosystem and propose economic methods that capture the marine ecosystem’s total economic value in relation to the opportunity cost of marine space. Values should be used to guide policy makers following the European directives and initiatives.

    Richmond, Peter; Hutzler, Stefan

    2013-01-01

    An understanding of the behaviour of financial assets and the evolution of economies has never been as important as today. This book looks at these complex systems from the perspective of the physicist. So called 'econophysics' and its application to finance has made great strides in recent years. Less emphasis has been placed on the broader subject of macroeconomics and many economics students are still taught traditional neo-classical economics. The reader is given a general primer in statistical physics, probability theory, and use of correlation functions. Much of the mathematics that is developed is frequently no longer included in undergraduate physics courses. The statistical physics of Boltzmann and Gibbs is one of the oldest disciplines within physics and it can be argued that it was first applied to ensembles of molecules as opposed to being applied to social agents only by way of historical accident. The authors argue by analogy that the theory can be applied directly to economic systems comprising...

    2005-01-01

    Broad and diverse ranges of activities are conducted within and by organized groups of individuals, including political, economic and social activities. These activities have recently become a subject of intense interest in economics and game theory. Some of the topics investigated in this collection are models of networks of power and privilege, trade networks, co-authorship networks, buyer-seller networks with differentiated products, and networks of medical innovation and the adaptation of new information. Other topics are social norms on punctuality, clubs and the provision of club goods and public goods, research and development and collusive alliances among corporations, and international alliances and trading agreements. While relatively recent, the literature on game theoretic studies of group formation in economics is already vast. This volume provides an introduction to this important literature on game-theoretic treatments of situations with networks, clubs, and coalitions, including some applications.

    2012-01-01

    Statistics is the branch of mathematics that deals with real-life problems. As such, it is an essential tool for economists. Unfortunately, the way you and many other economists learn the concept of statistics is not compatible with the way economists think and learn. The problem is worsened by the use of mathematical jargon and complex derivations. Here's a book that proves none of this is necessary. All the examples and exercises in this book are constructed within the field of economics, thus eliminating the difficulty of learning statistics with examples from fields that have no relation to business, politics, or policy. Statistics is, in fact, not more difficult than economics. Anyone who can comprehend economics can understand and use statistics successfully within this field, including you! This book utilizes Microsoft Excel to obtain statistical results, as well as to perform additional necessary computations. Microsoft Excel is not the software of choice for performing sophisticated statistical analy...

    This paper suggests how George Price's general mathematical theory of selection may be applied to economic data; and it is discussed how Price's equation may be expanded and interpreted so that it describes the mechanisms of Schumpeterian competition and thus the industrial dynamics underlying...... the evolution of economic data. The model is applied to the evolution of Danish labour productivity and systematic differences are identiffied between manufacturing industries and service industries. It is argued that similar results for the US and Sweden may be extracted from productivity studies following...... a certain methodology.

    This is a progress report on the first phase of a project to measure the economic impacts of a rapidly changing U.S. target base. The purpose of the first phase is to designate and test the macroeconomic impact analysis model. Criteria were established for a decision-support model. Additional criteria were defined for an interactive macroeconomic impact analysis model. After a review of several models, the Economic Impact Forecast System model of the U.S. Army Construction Research Laboratory was selected as the appropriate input-output tool that can address local and regional economic analysis. The model was applied to five test cases to demonstrate its utility and define possible revisions to meet project criteria. A plan for EIFS access was defined at three levels. Objectives and tasks for scenario refinement are proposed.

    The first two trading periods of the EU Emissions Trading Scheme (EU ETS) included extensive free allocation of emission allowances. Since in electricity production the carbon price is passed on - in an economically rational way - to the electricity price, the utility companies were able to reap substantial additional revenue, a significant amount of which result from the free allocation of emission allowances. Taking into account the nuclear fuel tax (introduced in Germany since 2011) which also aims to absorb additional revenue from the EU ETS, the additional revenue for utility companies from the first and second trading periods of the EU ETS considered in this paper are estimated to amount to Euro 38 billion (without nuclear fuel tax) or approx. Euro 35.6 billion (with nuclear fuel tax). The following results arise for the utilities under consideration in the period from 2005 to 2012: - For E.ON the additional revenue amounts to approx. Euro 13.4 billion (without nuclear fuel tax) or Euro 12.3 billion (with nuclear fuel tax); - For RWE the additional revenue amounts to approx. Euro 10.3 billion (without nuclear fuel tax) or Euro 9.6 billion (with nuclear fuel tax); - For Vattenfall Europe the additional revenue amounts to approx. Euro 5.7 billion, the consideration of the nuclear fuel tax causes only marginal changes because of the non-operational nuclear power plants Krummel and Brunsbuttel; - For EnBW the additional revenue amounts to approx. Euro 6.4 billion (without nuclear fuel tax) or Euro 5.9 billion (with nuclear fuel tax); - For Evonik the additional revenue remains unchanged by the introduction of the nuclear fuel tax and amounts to approx. Euro 2.1 billion for the period from 2005 to 2012. In the first two trading periods the free allocation of emission allowances to plants of energy-intensive industry which are outside of the electricity production sector and covered by the EU ETS sometimes substantially exceeded the emission levels of these plants
