  1. Directed Technical Change and Economic Growth Effects of Environmental Policy

    Kruse-Andersen, Peter Kjær


    A Schumpeterian growth model is developed to investigate how environmental policy affects economic growth when environmental policy also affects the direction of technical change. In contrast to previous models, production and pollution abatement technologies are embodied in separate intermediate...... unambiguously directs research efforts toward pollution abatement technologies and away from production technologies. This directed technical change reduces economic growth and pollution emission growth. Simulation results indicate that even large environmental policy reforms have small economic growth effects....... However, these economic growth effects have relatively large welfare effects which suggest that static models and exogenous growth models leave out an important welfare effect of environmental policy....

  2. Economic effectiveness of direct drill in maize production

    Žuža Desanka


    Full Text Available Within the concept of sustainable agriculture, raising environmental awareness of farmers and the preservation of natural resources, the implementation of the so-called conservation tillage began during the 1960s in the USA. It involves the application of a reduced or completely eliminated (no-till, zero tillage, direct drill sowing tillage, which prevents soil erosion, improves soil quality and biodiversity, also significantly reducing gas emissions by implementing a set of technical solutions. The application of this concept requires the existence of appropriate machinery that enables the use of direct seeding on land where plant residues of previous crops are present in the amount of minimum 30%. In addition to significant environmental impacts, this concept provides positive economic effects: for the whole society by eliminating the cost caused by soil degradation, but also for individual agricultural producers through the elimination of a significant number of complex machining operations and savings in diesel fuel and working hours of machines and employees. A comparative analysis of the economic effectiveness of maize production in terms of conventional tillage and no-till on a farm in Novi Sad showed that the application of direct drill allows skipping 4 to 5 machining operations, leading to a saving of 59 litres of diesel fuel per hectare of cultivated area while retaining the same average yield per ha, which resulted in increased profits by 4,246 RSD ha-1 compared to conventional tillage.

  3. The Effect of Foreign Direct Investment in Economic Growth from the Perspective of Nonlinear Dynamics

    Ch. K. Volos


    Full Text Available In today’s globalized economy one of the most crucial factors for the economic growth of a country, especially of a developing country, is the foreign direct investment, not only because of the transfer of capital but also of technology. In this work, the effect of foreign direct investments in a county’s economic growth by using tools of nonlinear dynamics is studied. As a model of the economic growth of a country, a well-known nonlinear discrete-time dynamical system, the Logistic map, is used. The system under study consists of two countries with a strong economic relationship. The source country of foreign direct investments is an industrialized, economically powerful and technologically advanced country that makes significant investments in the host country, which is a developing country and strong dependent from the source country. Simulation results of system’s behavior and especially the bifurcation diagrams reveal the strong connection between the countries of the proposed system and the effect of foreign direct investments in the economic growth of the host country.

  4. Economic effects of ocean acidification: Publication patterns and directions for future research.

    Falkenberg, Laura J; Tubb, Adeline


    Human societies derive economic benefit from marine systems, yet these benefits may be modified as humans drive environmental change. Here, we conducted the first systematic review of literature on the potential economic effects of ocean acidification. We identified that while there is a growing literature discussing this topic, assessments of the direction and magnitude of anticipated economic change remain limited. The few assessments which have been conducted indicate largely negative economic effects of ocean acidification. Insights are, however, limited as the scope of the studies remains restricted. We propose that understanding of this topic will benefit from using standard approaches (e.g. timescales and emissions scenarios) to consider an increasing range of species/habitats and ecosystem services over a range of spatial scales. The resulting understanding could inform decisions such that we maintain, or enhance, economic services obtained from future marine environments.




    Full Text Available In Romania, in the context of enrolling the national economy on the path of the market economy, the policy makers had taken a series of measures that had affected, on one side, the establishment of excises and taxes, and on the other side, its future adjustment. These actions, most of the times have not reached their planned purpose or even in some situations they had effects contrary to those expected. At company level the implications of the direct taxes imply: the number and configuration of economic agents, their legal structure, the territorial dispersion and their size, but also the economic- financial performances (turnover, gross investments, value added. The analysis performed in this sense in Romania, on the time horizon 1995-2009, tries to evaluate quantitatively and qualitatively the effects generated by the direct taxation over different macro and microeconomic measures.

  6. Economic, environmental and international trade effects of the EU Directive on energy tax harmonization

    Kohlhaas, Michael; Schumacher, Katja; Diekmann, Jochen; Schumacher, Dieter; Carmes, Martin


    In October 2003, the European Union introduced a Directive, which widens the scope of the EU's minimum taxation system from mineral oils to all energy products including coal, natural gas and electricity. It aims at reducing distortions that currently exist between Member States as well as between energy products. In addition, it increases previous minimum tax rates and thus the incentive to use energy more efficiently. The Directive will lead to changes in the energy tax schemes in a number of countries, in particular some southern Member Countries (Greece, Spain, Portugal) and most of the new Member States. In this paper, we analyze the effects of the EU energy tax harmonization with GTAP-E, a computable general equilibrium model. Particular focus is placed on the Eastern European countries, which became new members of the EU in May 2004. We investigate the effects of the tax harmonization on overall economic growth and sectoral development. Special attention is paid to international trade in order to analyze if competitiveness concerns, which have been forwarded in the context of energy taxation are valid. Furthermore, the effect on energy consumption and emissions and thus the contribution to the EU's climate change targets is analyzed

  7. The Effect of Exchange Rate and Inflation on Foreign Direct Investment and Its Relationship with Economic Growth in Nigeria

    Alex Ehimare OMANKHANLEN


    Full Text Available This study is on the effect of exchange rate and inflation on foreign direct investment and its relationship with economic growth. Its main objective is to find the effect of inflation and exchange rate and the bidirectional influences between FDI and economic growth in Nigeria. A thirty year period was studied. A linear regression analysis was used on the thirty year data to determine the relationship between inflation, exchange rate, FDI inflows and economic growth. The study reveals that FDI follow economic growth occasioned by trade openness which saw the entry of some major companies especially the telecommunication companies, while Inflation has no effect on FDI. However exchange rate has effect on FDI.

  8. A 3-stage model for assessing the probable economic effects of direct-to-consumer advertising of pharmaceuticals.

    Vogel, Ronald J; Ramachandran, Sulabha; Zachry, Woodie M


    The pharmaceutical industry employs a variety of marketing strategies that have previously been directed primarily toward physicians. However, mass media direct-to-consumer (DTC) advertising of prescription drugs has emerged as a ubiquitous promotional strategy. This article explores the economics of DTC advertising in greater depth than has been done in the past by using a 3-stage economic model to assess the pertinent literature and to show the probable effects of DTC advertising in the United States. Economics literature on the subject was searched using the Journal of Economic Literature. Health services literature was searched using computer callback devices. Spending on DTC advertising in the United States increased from $17 million in 1985 to $2.5 billion in 2000. Proponents of DTC advertising claim that it provides valuable product-related information to health care professionals and patients, may contribute to better use of medications, and helps patients take charge of their own health care. Opponents argue that DTC advertising provides misleading messages rather than well-balanced, evidence-based information. The literature is replete with opinions about the effects of prescription drug advertising on pharmaceutical drug prices and physician-prescribing patterns, but few studies have addressed the issues beyond opinion surveys. The economic literature on advertising effects in other markets, however, may provide insight. DTC advertising indirectly affects the price and the quantity of production of pharmaceuticals via its effect on changes in consumer demand.

  9. Lifecycle GHG emissions of palm biodiesel: Unintended market effects negate direct benefits of the Malaysian Economic Transformation Plan (ETP)

    Abdul-Manan, Amir F.N.


    Biodiesel expansion can lead to unintended effects that offset the direct GHG benefits of biofuels. Two documented unintended effects are the indirect land use change (ILUC) and indirect energy use change (IEUC). ILUC has been included in many lifecycle GHG studies of biofuels, but IEUC has remained relatively elusive. This paper presents an updated assessment of the lifecycle GHG emissions of palm biodiesel from Malaysia and, for the first time, incorporating the two estimated indirect effects simultaneously. Future GHG emissions of palm biodiesel are projected by taking into account of Malaysia's Economic Transformation Programme (ETP) that aims to reform the oil palm industry in order to achieve a high-income nation. Uncertainties associated with lifecycle GHG models were dealt with using Monte Carlo simulation in order to identify the breadth and likelihood of GHG reductions relative to petroleum-based fuels in the context of the European directives. This study has shown that the ETP, if successfully implemented, can significantly improve the direct GHG emissions of palm biodiesel, but the benefits are offset by the rise in global emissions due to ILUC and IEUC. Biofuel policies should also include IEUC, in addition to ILUC, to avoid GHG emissions leakages. - Highlights: • Estimate current and future lifecycle GHG emissions of Malaysian palm biodiesel. • Evaluate the GHG effects of Malaysia's Economic Transformation Plan (ETP). • Direct GHG benefits of biodiesel offset by indirect market effects. • Palm biodiesel unlikely to enable global GHG emissions reductions. • Global biofuel policy must account for indirect effects.

  10. A direct Newton-Raphson economic dispatch

    Lin, C.E.; Chen, S.T.; Huang, C.L.


    This paper presents a new method to solve the real-time economic dispatch problem using an alternative Jacobian matrix considering system constraints. The transition loss is approximately expressed in terms of generating powers and the generalized generation shift distribution factor. Based on this expression, a set of simultaneous equations of Jacobian matrix is formulated and solved by the Newton-Raphson method. The proposed method eliminates the penalty factor calculation, and solves the economic dispatch directly. The proposed method obtains very fast solution speed and maintains good accuracy from test examples. It is good approach to solve the economic dispatch problem

  11. Environmental policy and technological change: The effects of economic incentives and direct regulation on energy-saving innovation

    Newell, Richard G., Jr.

    Over the long run, the impacts of environmental policies will be greatly affected by the influence these policies have on the rate and direction of technological change. In particular, the roles played by energy prices and product regulation in energy-saving technology innovation are exceptionally important considerations in modeling climate change and evaluating alternative policy options. We analyze the effects of energy prices and energy-efficiency regulations on the menu of air conditioner and water heater models available on the market over a period of more than three decades, measuring their innovation in terms of improvements in the products' underlying characteristics. Through estimation of a series of "characteristics transformation surfaces," we find that during less than four decades, substantial innovation in these products reduced the total capital and operating costs of air conditioning by one-half and water heating by more than one-fifth. Although the overall rate of innovation in these products appears to be independent of energy prices and regulations, the evidence suggests that the direction of innovation may be responsive to energy price changes. This would imply that energy price increases induced innovation in a direction that lowered the capital cost tradeoffs inherent in producing more energy-efficient products. The evidence supporting "regulation-induced" changes in these tradeoffs is much weaker. Our estimates indicate that about one- to two-fifths of the energy-efficiency improvements in these products from 1973 to 1993 were associated with historical changes in energy prices. We also find that this responsiveness to price changes increased substantially after product labeling requirements came into effect, and that minimum efficiency standards had a significant positive effect on average efficiency levels. Nonetheless, a sizeable portion of historical efficiency improvements in these technologies is associated with the products' overall

  12. Direct economic benefits associated with dietetic internships.

    Conklin, M T; Simko, M D


    We explored the direct economic benefits of hospital dietetics departments sponsoring an internship for dietetics studies. Forty-five dietetics departments in US hospitals participated in a mail survey that involved comprehensive data collection procedures using three instruments, including activity logs recorded by 298 dietitians and interns. Direct benefits were defined as the net student labor provided to the department during routine and staff relief experiences that released professional labor for other work. Net student productivity during routine assignments was calculated by subtracting the time dietitians spent teaching during a typical work week from the amount of time dietetic interns spent performing professional services without direct supervision. Student productivity during staff relief rotations was calculated by multiplying the number of students assigned to this type of experience by the length of the rotation. While involved in routine learning experiences, dietetic interns provided a direct benefit. The difference between the time interns spent in independent, professional service in the departments and the time dietitians spent in activities designed specifically for teaching was a mean of 29 hours in favor of the students. All departments received a direct benefit from assigning dietetic interns to a staff relief rotation. The median number of weeks of student labor gained by the departments per year was 24. A paired t test was used to analyze the difference between the time dietitians devoted to teaching interns and the time students spent in independent, professional service in the departments. The difference was very highly significant (P impact of their supervised practice program on the sponsoring organization.

  14. Foreign Direct Investment, Economic Freedom and Economic Performance in Sub-Saharan Africa

    Kazeem Bello Ajide


    Full Text Available The controversies that trailed whether direct impact of Foreign Direct Investment (FDI on growth are conditional on a certain intermediating links or not, has made an inquiry into the likely mediating links in the FDI growth space a recurring subject of discourse.While the importance of institution has prominently featured as playing a vital role on the one hand, economic freedom (a key institutional component has consistently been elected, as a good candidate surrogate on the other hand. It is against this backdrop this study examines the effect of FDI inflow on economic performance in the SSA region giving prominence to economic freedom. The results support the view that economic freedom is germane in influencing the economic-wide performance in the region but have insignificant effects on the different sector performances. It is recommended that economic freedom be given priority in the region and FDI should be attracted to other sectors other than the primary sector, as it is the case.

  20. Outward foreign direct investments and home country's economic growth

    Ciesielska, Dorota; Kołtuniak, Marcin


    The study examines the time stability of the causality direction and cross-correlations between the home country's economic growth and pace of growth of its outward foreign direct investment (OFDI) stocks within the complex system of the Polish national economy. The research has been performed in order to verify, using both the time and frequency domains time series analyses, if economic agents' long term decisions on outward foreign direct investments, leading to cross-border value chains and production fragmentation processes, are of adaptive or predictive character. Consequently, the aim was to check if the home country's economic growth leads the internationalization processes of domestic enterprises, which stays in line with Dunning's Investment Development Path (IDP) paradigm, or if these complex processes, thanks to entrepreneurs' ability to formulate relevant rational expectations, precede the home country's economic growth, which would be supported with the introduction of the policy on reinforcing the internationalization processes of domestic enterprises. The presence of the unidirectional economic growth-led internationalization, consistent with the IDP concept's base assumptions, has been ascertained by the results of the short term Granger causality tests. Nevertheless, the results of the wavelet analyses, supported with the results of the econometric block exogeneity long term causality Wald tests, have revealed that in the long term the OFDI stocks' growth permanently precedes the home country's economic growth, which stays in the unequivocal contrast with the IDP paradigm's premises, as well as with the indicated above short term Granger causality tests' outcomes and indicates that economic agents' choices are not strictly of adaptive but also of predictive character, which influences the current state of knowledge on economic complex systems' characteristics. Such a result is of a great importance in the light of the existence of the significant

  4. Economic benefits of the EU Ecodesign Directive. Improving European economies

    Molenbroek, E.; Cuijpers, M.; Blok, K.


    The EU Ecodesign Directive aims at reducing the environmental impact of a number of products sold in the EU, with emphasis on their energy consumption. Ecofys investigated economic benefits related to the Directive. A correct implementation of the EU Ecodesign Directive would yield yearly savings of up to 600 TWh of electricity and 600 TWh of heat in 2020. In addition to these environmental benefits, this study identified important economic advantages like: Net savings for European consumers and businesses of 90 billion euro per year (1% of EU's current GDP) in the year 2020; Reinvesting these savings in other sectors of the economy would result in the creation of one million jobs; Dependency on imports of energy would be reduced by 23% and 37% for natural gas and coal, respectively. This means the EU could slash natural gas imports from Russia by more than half and imports of coal from Russia could be stopped altogether.

    Full Text Available An economic regime might take the form in which extractive institutions do not allow for the proper development of foreign direct investment. In consequence these countries cannot fully benefit from economic aspects of globalization and increasing standards of living. This is the case of Ukraine, a country with very good location advantages and a well-educated workforce that attracts only the murky type of FDI. It is a country that is troubled by corruption and political instability but at the same time a country that began the path to finding its national identity by fighting against extractive institutions.

    Full Text Available We live in a time when the world’s economy is in a constantly change. Foreign direct investments flows are in actual economy one of the most dynamic and prospective part of the world’s economy being in a continuous globalization. These international financial flows determine the traders who take part at the world’s economy to know to adopt a specific management in the international affairs field. We are viewers of an unprecedented expansion of foreign direct investments. The main objective of the paper is to analyze the foreign direct investments flows in Black Sea Economic Cooperation. This study is based on UNCTAD reports and on an econometrical model which gives us the possibility to create different analysis concerning FDI flow in this cooperation. So we defined a simple regression model, in which the dependent variable is represented by Nominal and real GDP, total and per capita, variable explicated by FDI flows, using as method the Least Squared, including 19 observations. Through this paper, we tried to illustrate the relation between the FDI flows and the economic growth rate in the past years inRomania, member of Black Sea Economic region. In line with a general upward trend in FDI to Central and Eastern Europe, inward FDI to the Russian Federation held steady between 1998 and 2001, at an annual average of $2.8 billion. In Black Sea Economic region, Russian average is the biggest one, Russia being a leader country in warding FDI. The Russian Federation is by far the leading investor country in the region, accounting for more than 75% of its annual outflows. Inward and outward direct investments flows in Russia have reached in 2009 an amount of $38,722 billion. In Romania, following years of stagnation at very low levels, 1991 to 1997, FDI flows reached $1.1 billion in 2002. Inflows to Bulgaria peaked at $1 billion in 2000; the surge is largely due to flows from developed countries. Inward and outward direct investments flows in

  10. Economic effects of peak oil

    Lutz, Christian; Lehr, Ulrike; Wiebe, Kirsten S.


    Assuming that global oil production peaked, this paper uses scenario analysis to show the economic effects of a possible supply shortage and corresponding rise in oil prices in the next decade on different sectors in Germany and other major economies such as the US, Japan, China, the OPEC or Russia. Due to the price-inelasticity of oil demand the supply shortage leads to a sharp increase in oil prices in the second scenario, with high effects on GDP comparable to the magnitude of the global financial crises in 2008/09. Oil exporting countries benefit from high oil prices, whereas oil importing countries are negatively affected. Generally, the effects in the third scenario are significantly smaller than in the second, showing that energy efficiency measures and the switch to renewable energy sources decreases the countries' dependence on oil imports and hence reduces their vulnerability to oil price shocks on the world market. - Highlights: ► National and sectoral economic effects of peak oil until 2020 are modelled. ► The price elasticity of oil demand is low resulting in high price fluctuations. ► Oil shortage strongly affects transport and indirectly all other sectors. ► Global macroeconomic effects are comparable to the 2008/2009 crisis. ► Country effects depend on oil imports and productivity, and economic structures.

    Hu, Huimei; Sawhney, Monika; Shi, Lizheng; Duan, Shengnan; Yu, Yunxian; Wu, Zhihong; Qiu, Guixing; Dong, Hengjin


    Type 2 diabetes is associated with acute and chronic complications and poses a large economic, social, and medical burden on patients and their families as well as society. This study aims to evaluate the direct economic burden of type 2 diabetes in China. systematic review on cost of illness, health care costs, direct service costs, drug costs, and health expenditures in relation to type 2 diabetes was conducted up to 2014 using databases such as Pubmed; EBSCO; Elsevier ScienceDirect, Web of Science; and a series of Chinese databases, including Wanfang Data, China National Knowledge Infrastructure (CNKI), and the China Science and Technology Journal Database. Factors influencing hospitalization and drug fees were also identified. (1) estimation of the direct economic burden including hospitalization and outpatient cost of type 2 diabetes patients in China; (2) evaluation of the factors influencing the direct economic burden. Articles only focusing on the cost-effectiveness analysis of diabetes drugs were excluded. The direct economic burden of type 2 diabetes has increased over time in China, and in 2008, the direct medical cost reached $9.1 billion, Both outpatient and inpatient costs have increased. Income level, type of medical insurance, the level of hospital care, and type and number of complications are primary factors influencing diabetes related hospitalization costs. Compared to urban areas, the direct non-medical cost of type 2 diabetes in rural areas is significantly greater. The direct economic burden of type 2 diabetes poses a significant challenge to China. To address the economic burden associated with type 2 diabetes, measures need to be taken to reduce prevalence rate and severity of diabetes and hospitalization cost.

  16. Implications Of Foreign Direct Investment, Financial Development And Real Exchange Rate For Economic Growth In Cameroon

    Victalice Ngimanang Achamoh


    Full Text Available This paper assesses the effects of foreign direct investment (FDI, financial development and real exchange rate (RER on economic growth in Cameroon using Cameroon’s annual time series data spanning the period 1977 - 2010. To address these objectives, residual based Engle-Granger test, the OLS based Autoregressive Distributive Lag (ARDL bound testing and maximum likelihood based Johansen cointegration techniques are employed. Results of Unit roots tests show that all the series possessed unit roots at level or first difference form. The ARDL model and VECM results reveal that the RER has a significant negative effect on economic growth, while FDI and Financial Development relate positively to economic growth. These findings have implications for stimulating economic growth by increasing efficiency of the financial sector in allocating credit to the private sector and preventing real exchange rate appreciation in the shortrun.

    Full Text Available The aim of the paper was to explore economic effects of corruption in judiciary. The examination included the analysis of economic features of judiciary and economic mechanisms of corruption in judiciary within the theoretical framework of Backer's model of criminal behavior. The analysis demonstrates that corruption in judiciary violates the rule of law, hence undermines the fundaments of market economy and specialization, i.e. social division of labor as the ground for improving economic efficiency. As to the static economic efficiency, the most important effect of corruption in judiciary is transaction costs that are generated and the consequent allocative inefficiency. As to the dynamic economic efficiency, corruption decreases economic growth rates and reallocates recourses from productive to distributive activities. The effects of corruption in judiciary to economic inequality are not significant, particularly not comparing with the already identified effects to the economic efficiency.

  20. Interaction of Economic Freedom and Foreign Direct Investment Globally: Special Cases from Neglected Regions

    Yhlas Sovbetov


    Full Text Available This paper studies the macroeconomic impact of economic freedom on foreign direct investments inflows in both global and regional panel analyses involving 156 countries through the period of 1995-2016. Unlike to prior literature, it includes often neglected nations such as Fragile and Conflict-Affected states, Sub-Saharan, Oceanian, and Post-Soviet countries. The paper finds a positive impact of economic freedom on FDI under fixed-effects model in global case where a unit change in economic freedom scales FDI inflows up to 1.15 units. More specifically, all 9 regions also refer to positive and significant impact of economic freedom on FDI. The highest impact is recorded in European countries, whereas the lowest ones are documented in Fragile-Conflict affected states, Sub-Saharan zone, and Oceanian countries.

  1. Direct regional energy/economic modeling (DREEM) design

    Hall, P.D.; Pleatsikas, C.J.


    This report summarizes an investigation into the use of regional and multiregional economic models for estimating the indirect and induced impacts of Federally-mandated energy policies. It includes an examination of alternative types of energy policies that can impact regional economies and the available analytical frameworks for measuring the magnitudes and spatial extents of these impacts. One such analytical system, the National Regional Impact Evaluation System (NRIES), currently operational in the Bureau of Economic Analysis (BEA), is chosen for more detailed investigation. The report summarizes the models capabilities for addressing various energy policy issues and then demonstrates the applicability of the model in specified contexts by developing appropriate input data for three scenarios. These scenarios concern the multi-state impacts of alternative coal-mining-development decisions, multi-regional impacts of macroeconomic change, and the comprehensive effects of an alternative national energy supply trajectory. On the basis of this experience, the capabilities of NRIES for analyzing energy-policy issues are summarized in a concluding chapter.

    Full Text Available The paper examines the potential determinants of foreign direct investment inflows into the region of Eurasian Economic Union, as well as incentives for investment into other neighboring countries. In the first model, the authors test a hypothesis on country specific foreign direct investment determinants for the Eurasian Economic Union region. The results of fixed effects estimation show that gross domestic product, infrastructure development and secondary education enrollment have a positive statistically significant effect on the foreign direct investment inflows into the region. Conversely, the impact of Customs Union on foreign direct investment appeared to be negative. Furthermore, in the second model of the natural experiment, the authors empirically test the hypothesis on Customs Union’s effect on foreign direct investment while controlling for both country and time effects. The model includes evaluating the impact of the policy change on foreign investment inflows. The natural experiment outcome also points to the negative effect of Eurasian economic integration on foreign direct investment inflows. Although the countries of Eurasian Economic Union have relatively business friendly regulations, such procedures as enforcing contracts, resolving insolvencies and dealing with construction permits are time-consuming. For attracting foreign investment, it is advisable to facilitate such procedures and make the process of setting up a new business less onerous. The research can be used as an outline for further examining of Eurasian economic integration and apart from that, the study results can be applied for practical purposes of policy elaboration aimed at stimulating foreign direct investment into the Eurasian Economic Union.

  3. Direct healthcare costs and cost-effectiveness of acute coronary syndrome secondary prevention with ticagrelor compared to clopidogrel: economic evaluation from the public payer's perspective in Poland based on the PLATO trial results.

    Pawęska, Justyna; Macioch, Tomasz; Perkowski, Piotr; Budaj, Andrzej; Niewada, Maciej


    Ticagrelor is the first reversibly binding oral P2Y12 receptor antagonist designed to reduce clinical thrombotic events in patients with acute coronary syndrome (ACS). Compared to clopidogrel, ticagrelor has been proven to significantly reduce the rate of death from vascular causes, myocardial infarction (MI), or stroke without an increase in the rate of overall major bleeding in patients who have an ACS with or without ST-segment elevation (STEMI and NSTEMI) or unstable angina (UA). To evaluate the cost-effectiveness and healthcare costs associated with secondary prevention of ACS using ticagrelor or clopidogrel in patients after STEMI, NSTEMI and UA. An economic model based on results from the PLATO trial was used to evaluate the cost-effectiveness of one-year therapy with ticagrelor or clopidogrel. The structure of the model consisted of two parts, i.e. the decision tree with one-year PLATO results and the Markov model with lifelong estimations, which exceeded PLATO follow-up data. The model was adjusted to Polish settings with country-specific data on death rates in the general population and direct medical costs calculated from the public payer's perspective. Costs were derived from the National Health Fund (NHF) and the Ministry of Health and presented in PLN 2013 values. Annual mean costs of second and subsequent years after stroke or MI were obtained from the literature. Uncertainty of assumed parameters was tested in scenarios and probabilistic sensitivity analyses. The adopted model allowed the estimation of an incremental cost-effectiveness ratio for life years gained (LYG) and an incremental cost-utility ratio for quality adjusted life years (QALY). Total direct medical costs to the public payer at a one year horizon were 2,905 PLN higher with ticagrelor than with clopidogrel. However, mean healthcare costs at a one year horizon (excluding drug costs and concomitant drugs) were 690 PLN higher for patients treated with clopidogrel. In a lifetime horizon

  5. Foreign direct investment and economic growth: A theoretical framework

    Edmore Mahembe


    Full Text Available The relationship between FDI and economic growth has attracted considerable attention over the years. Despite the important role played by FDI in economic growth, a number of policy-makers have not fully understood the theoretical linkage between FDI and economic growth. The aim of this paper, therefore, is to review the theoretical literature on the relationship between FDI and economic growth in a stylized fashion. The theoretical literature reviewed in this study show that FDI is a key contributor to the economic growth of the host country. FDI affects economic growth through two broad channels: (i FDI can encourage the adoption of new technologies in the production process through technological spillovers; and (ii FDI may stimulate knowledge transfers, both in terms of labour training and skill acquisition, and also by introducing alternative management practices and better organisational arrangements.

    Haaparanta, P.; Jerkkola, J.; Pohjola, J.


    The CO 2 emissions can be reduced by using economic instruments, like carbon tax. This project included two specific questions related to CO 2 taxation. First one was the economic effects of increasing CO 2 tax and decreasing other taxes. Second was the economic adjustment costs of reducing net emissions instead of gross emissions. A computable general equilibrium (CGE) model was used in this analysis. The study was taken place in Helsinki School of Economics

  7. Economic Effects Real Estate Tax

    Tadić Milan


    Full Text Available The real estate tax is usually a fiscal instrument which performs the property tax. When it comes to real property or immovable this term include: apartments, houses, land, cottages, excess housing landscape and more. The real estate tax as a form of the fiscal charges ownership or use of certain forms of real estate, and the revenue from this tax is levied on the area where the property is located regardless of the place of residence of its owner. The tax base for the calculation of this tax usually consists of the market, estimated or annuity value of certain real estate. This form of taxation in the Republic of Serbian applies from 1.1.2012., and its introduction has been replaced by former property taxes. The differences between the two concepts mentioned taxes are numerous and significant. Among the more important are: subject to taxation under the new concept of the real estate rather than law, a taxpayer is any property owner rather than the holder of rights to immovable property tax base is the market value of real estate which is replaced by the payment of taxes per square meter of usable area, the rate of property tax is determined local government, which can not be lower than 0.05% of the estimated value of the real estate nor higher than 0.5% of the appraised value of real estate. The last change, ie. The new law on Property Tax from 5.11.2015. was determined by the tax rate to 20%. The fact that local governments each of them determines the tax rate on real estate which range from high to low rates of multiple, makes this tax is progressive. Progression is particularly expressed in the distinction applied tax rates of developed and undeveloped municipalities, where we have a case that less developed tolerate a higher tax burden, which leads to negative economic effects. However, real estate tax has its own economic and social characteristics which must be aligned with the objectives of tax policy. This means that the real estate tax

  8. Economic summary of woody biomass direct combustion and gasification alternatives


    A base case analysis indicates that acceptable rates of return on investment are possible when utilizing wood as a commercial scale boiler fuel. Principal variables include the availability of cost competitive wood fuel over the term of the loan and overall installed cost for the system. In some cases the cost of coal at the point of end use will be comparable with wood. Hardware costs will determine system economics and applicable air quality standards, or lack thereof, will play an important role. The overall economics of using wood for fuel are extremely site specific. The additional 10 percent energy tax credit greatly enhances the economics of a wood fired system, although system economics are very attractive without this tax incentive. Cost of money does not seem to drastically affect overall system economics.

  9. Socio-economic effects of bioenergy

    Maeenpaeae, I.; Maennistoe, J.


    This report studies the socio-economic effects and benefits of domestic fuels - peat and wood, and agricultural energy plants also - in power and heat generation. For evaluation of employment and income effects, it compares the costs of domestic as well a imported fuels as regards production, transportation and power stations by looking especially at the direct labour input and inputs in terms of intermediate products and investment. Their indirect employment effects and allocation to domestic factor income and imports are introduced by means of an input-output model. The net changes in the disposable incomes of local households, firms and municipalities, the government and others are derived from factor incomes by means of income redistribution. The economy-wide profitability of the domestic fuels was evaluated using a macroeconomic model, the FMS model system. The particular question posed was how much the domestic fuels could cost at most to be economically profitable. It was shown that macroeconomic profitability is affected essentially by real production costs and the import prices of the imported fuels. Subsidies and differentiated fuel taxes have only little impact on the macroeconomic profitability although they change the private profitability of the fuels considerably. This is why fuel taxes were excluded in the macroeconomic profitability evaluations

  13. Economic and regional consequences of direct payments under the current CAP philosophy

    Věra Bečvářová


    Full Text Available The paper deals with one of the key instruments of the actual EU Common Agricultural Policy (the CAP, the direct payments. The economic as well as the regional implications of application for direct payments in the CAP strategy are evaluated there. The study deals with the economic costs, direct and indirect effects of such type of subsidy in general and a demonstration thereof in the context of the development of the European model of agriculture. Based on the economic principle of this type of transfer evalution, the processes of the income redistribution in the framework of global/common policy in general is characterized. It explains the causes as well as the nature of implementation of this instrument in the reform processes in the last twenty years, focusing on the reasons and consequences of different application in the original and the new EU member states. It considers the question of whether this type of support to agriculture is truly a tool that does not interfere with market conditions affect the respective competitive ability of agricultural producers. In the context of changes to income support in agriculture in the CAP development process, the effect of decoupled payments on the pricing within the agricultural commodity markets is specified. At the same time the work deals with a broader social context and social impact of the differing forms of support in European regions.

  14. Effects of Credit on Economic Growth, Unemployment and Poverty

    Mangasa Augustinus Sipahutar


                  Effect of credit on economic growth, unemployment and poverty provides evidence from Indonesia on the role of banks credit for promoting economic growth and reducing both unemployment and poverty.  To document the link between banks credit and economic growth, we estimate a VAR model and variance decompositions of annual GDP per capita growth rates to examine what proxy measures of banks credit are most important in accounting for economic growth over time and how much they contribute to explaining economic growth.  We also estimate an ECM to document the relationship between banks credit to both unemployment and poverty.  This paper revealed bi-direction causality between banks credit and economic growth.  Banks credit promotes economic growth and economic growth affects credit depth and financial development.  Furthermore, banks credit is a growth accelerating factor on Indonesian economic growth.  Banks credit is an endogenous growth and a good predictor on Indonesian economy. Our estimation model explained that credit allocated by banks increases business escalation to the real sectors then promotes economic growth, decreases unemployment rate through increasing in labor demanded, increases income and then decrease poverty.  This overall transmission mechanism just occurred through presence of banks credit by increasing money supply to the real sectors, promotes growth and social welfare.   Keywords :  banks credit, economic growth, growth accelerating factor, poverty, unemployment   JEL Classification : E51, E52, E58

  15. Combining of Direct Search and Signal-to-Noise Ratio for economic dispatch optimization

    Lin, Whei-Min; Gow, Hong-Jey; Tsai, Ming-Tang


    This paper integrated the ideas of Direct Search and Signal-to-Noise Ratio (SNR) to develop a Novel Direct Search (NDS) method for solving the non-convex economic dispatch problems. NDS consists of three stages: Direct Search (DS), Global SNR (GSNR) and Marginal Compensation (MC) stages. DS provides a basic solution. GSNR searches the point with optimization strategy. MC fulfills the power balance requirement. With NDS, the infinite solution space becomes finite. Furthermore, a same optimum solution can be repeatedly reached. Effectiveness of NDS is demonstrated with three examples and the solutions were compared with previously published results. Test results show that the proposed method is simple, robust, and more effective than many other previously developed algorithms.

  16. The Foreign Direct Investment and Economic Growth - Case Study for Kosovo

    Dr.Sc. Myrvete Badivuku - Pantina


    Full Text Available This research paper will explain the impact and relationship between the Foreign Direct Investment (FDI and economic growth, Kosovo case. The used data in research are secondary data and cover a period of time between 2008 and 2013. By using STATA program for calculation and by various regression analyses (descriptive statistics, linear regression and correlation relationships have been identified between involved variables in research, where economic growth is defined as dependent variable, whereas FDI, interest rate and real effective and exchange rate (REER are defined as independent variables. The main results in this research paper indicate that FDI has a positive relation (0.011 but non-significant effect (T2 on economic growth in Kosovo. The real effective exchange rate has a negative (-0.347 and non-significant relation (T<2 with economic growth. The main activities of FDI in overall Kosovo's economy are: real estate, transport and telecommunication, financial and manufacture services, construction, etc. The main conclusion is that the Kosovo institutions should create a favorable environment, such as: political stability, enforcement of justice, reduction of trade barriers, Kosovo should also create appropriate policy for protection of foreign investors, investment security, fair competition and institutional support. This will impact the drastic improvement and increase of FDI. In 2013 Kosovo had an FDI percentage of 5% of GDP while in 2007 it was over 13% of Kosovo's GDP.

Damages are estimated for a disaster with both 200,000 and 250,000 total dead and missing (i.e., the range of mortality that the earthquake is estimated to have caused) using Haiti’s economic and demographic data. The base estimate is US$8.1bn for a death toll of 250,000, but for several reasons this may be a lower- bound estimate. An ...

  2. Impact of Foreign Direct Investment and Economic Growth in Ghana: A Cointegration Analysis

    Samuel Antwi


    Full Text Available Foreign direct investment (FDI has been an important source of economic growth for Ghana, bringing in capital investment, technology and management knowledge needed for economic growth. This paper aims to study the relationship between FDI and economic growth in Ghana for the period 1980-2010 using time series data. The data used in this study was mainly secondary data collected from the period, 1980 to 2010 consisting of yearly observations for each variable. The real GDP growth and foreign direct investment net inflows as percent of GDP (FDI ratio data were taken from the World Banks World Development Indicators 2011 CD Rom. Yearly time series data covering the period 1980-2010 for which data was available was used. The cointegration methodology is applied on yearly data of FDI, GDP and GNI to determine the extent to which these variables are related. The study establishes that a long-run equilibrium and causal relationship exists between the dependent variable; FDI and the two independent variables under consideration namely, GDP and GNI. It was determined that in the short-run, effects of GDP and GNI volatility on FDI are nearly imaginary. These findings hold practical implications for policy makers, government and investors.

  4. The contribution of foreign direct investment to clean energy use, carbon emissions and economic growth

    Lee, Jung Wan


    The paper investigates the contributions of foreign direct investment (FDI) net inflows to clean energy use, carbon emissions, and economic growth. The paper employs cointegration tests to examine a long-run equilibrium relationship among the variables and fixed effects models to examine the magnitude of FDI contributions to the other variables. The paper analyzes panel data of 19 nations of the G20 from 1971 to 2009. The test results indicate that FDI has played an important role in economic growth for the G20 whereas it limits its impact on an increase in CO 2 emissions in the economies. The research finds no compelling evidence of FDI link with clean energy use. Given the results, the paper discusses FDI's potential role in achieving green growth goals. - Highlights: ► FDI inflows strongly lead to economic growth in the G20. ► FDI inflows lead to an increase in energy use in the G20. ► FDI inflows are in no relation to CO 2 emissions in the G20. ► FDI inflows are in no relation to clean energy use in the G20. ► Economic growth is in negative relation to CO 2 emissions in the G20

  5. Environmental Disaster and Economic Change: Do tropical cyclones have permanent effects on economic growth and structure?

    Jina, A.; von der Goltz, J.; Hsiang, S. M.


    Natural disasters have important, often devastating, effects upon economic growth and well-being. Due to this, disasters have become an active area of recent research and policy attention. However, much of this research has been narrowly focused, relying on anecdotal evidence and aggregated data to support conclusions about disaster impacts in the short-term. Employing a new global data set of tropical cyclone exposure from 1960 to 2008, we investigate in greater detail whether permanent changes in economic performance and structure can result from these extreme events in some cases. Our macro-economic analyses use the World Development Indicator dataset and have shown promising results: there are dramatic long-term economic transformations associated with tropical cyclones across a number of countries and industries. This effect is most clearly seen in Small Island Developing States (SIDS) and some countries in Latin America, where negative changes in long-term growth trends are observed in the years following a large tropical cyclone. In many economies with a high exposure to tropical cyclone damage, there are noticeable structural changes within the economy. The impacts of disasters might be expressed through various economic and social channels, through direct loss of lives and infrastructure damage; for instance, the destruction of infrastructure such as ports may damage export opportunities where replacement capital is not readily available. These structural changes may have far-reaching implications for economic growth and welfare. Larger nations subjected to the impacts of tropical cyclones are thought to be able to relocate economically important activities that are damaged by cyclones, and so long-term trend changes are not observed, even for events that cause a large immediate decrease in national productivity. By investigating in a more rigorous fashion the hypothesis that the environment triggers these permanent economic changes, our work has

  6. Economic effectiveness of disease management programs: a meta-analysis.

    Krause, David S


    The economic effectiveness of disease management programs, which are designed to improve the clinical and economic outcomes for chronically ill individuals, has been evaluated extensively. A literature search was performed with MEDLINE and other published sources for the period covering January 1995 to September 2003. The search was limited to empirical articles that measured the direct economic outcomes for asthma, diabetes, and heart disease management programs. Of the 360 articles and presentations evaluated, only 67 met the selection criteria for meta-analysis, which included 32,041 subjects. Although some studies contained multiple measurements of direct economic outcomes, only one average effect size per study was included in the meta-analysis. Based on the studies included in the research, a meta-analysis provided a statistically significant answer to the question of whether disease management programs are economically effective. The magnitude of the observed average effect size for equally weighted studies was 0.311 (95% CI = 0.272-0.350). Statistically significant differences of effect sizes by study design, disease type and intensity of disease management program interventions were not found after a moderating variable, disease severity, was taken into consideration. The results suggest that disease management programs are more effective economically with severely ill enrollees and that chronic disease program interventions are most effective when coordinated with the overall level of disease severity. The findings can be generalized, which may assist health care policy makers and practitioners in addressing the issue of providing economically effective care for the growing number of individuals with chronic illness.

  8. The reform of the European energy tax directive: Exploring potential economic impacts in the EU27

    Rocchi, Paola; Serrano, Mònica; Roca, Jordi


    The aim of this study is to analyze the effect that the Energy Tax Directive reform proposed in 2011 would have, if implemented, on the level of prices in the different sectors of the 27 countries of the European Union. We apply a multiregional and multisectoral model of trade flows that takes into account all the intersectoral and intercountry interdependences in the production processes. Using the World Input–Output Database we perform two different simulations. The first one considers the tax changes proposed by the reform; the second one shows the impact the reform would have entailed if it were applied also to sectors belonging to the European Trade System. The main finding of the first simulation shows that the new energy tax regime would have had a low economic cost in terms of impact on prices (less than 1% in all the countries). So, the concerns about competitiveness do not find empirical support in our results, suggesting the need for further analyses to find out the reasons that caused the failure of a reform that was an important step to introduce a taxation explicitly linked to CO 2 emissions. The second simulation, however, leads to strongly different results, pointing out the relevance of maintaining significant economic incentives to reduce carbon emissions for the European Trade System sectors, by improving the emission market performance or by applying carbon taxation also to these sectors. - Highlights: • We analyze the reform of the European energy tax proposed in 2011, rejected in 2012. • We simulate what potential economic effect this reform would have if implemented. • We find that this reform would have weak effects on prices in all 27 EU countries. • We study the effect of the reform if applied to European emission market sectors. • In this second scenario, the economic impacts would have been much stronger

  9. Effects of economic interactions on credit risk

    Hatchett, J P L; Kuehn, R


    We study a credit-risk model which captures effects of economic interactions on a firm's default probability. Economic interactions are represented as a functionally defined graph, and the existence of both cooperative and competitive business relations is taken into account. We provide an analytic solution of the model in a limit where the number of business relations of each company is large, but the overall fraction of the economy with which a given company interacts may be small. While the effects of economic interactions are relatively weak in typical (most probable) scenarios, they are pronounced in situations of economic stress, and thus lead to a substantial fattening of the tails of loss distributions in large loan portfolios. This manifests itself in a pronounced enhancement of the value at risk computed for interacting economies in comparison with their non-interacting counterparts

  10. The relationship between foreign direct investment and economic growth in South Africa: Vector error correction analysis

    Tshepo S. Masipa


    Full Text Available Orientation: From the Growth, Employment and Redistribution (GEAR strategy of 1996 to the currently implemented National Development Plan (NDP, the need to attract more foreign investors and promote exports in pursuit of economic growth and job creation has been emphasised. Research purpose: It is within this context that the purpose of this article was to determine the nexus between foreign direct investment (FDI inflows and economic growth from 1980 to 2014. Research design, approach and method: The vector error correction model is employed to determine and estimate the long-run relationship between the variables in the model. Main findings: From the findings, it was found that economic growth shares a positive relationship with both FDIs and the real effective exchange rate, while sharing a negative long-run relationship with government expenditure. Practical and managerial implications: The article contributes towards the on going debates on the impact of FDIs on economic growth and job creation in the recipient countries. Accordingly, its findings reinforce the importance of attracting FDIs in South Africa and to what extent they affect economic growth and employment. Contribution or value-add: From a policy perspective, the attraction of foreign investors must target sources that can create jobs and boost the South African economy. It is vital for the government to strengthen its machinery to fight corruption to create an environment conducive for foreign investors. Hence, this article suggests that South Africa’s capacity to grow and create jobs also depends on the country’s performance to enhance gross domestic product growth and attract more FDIs. The attraction of FDIs should, however, not be seen as an end in itself but also as a means of supporting other initiatives such as eradicating poverty and inequalities in South Africa.

  11. Tax Shift by Economic Functions and Its Effect on Economic Growth in the European Union

    Irena Szarowská


    Full Text Available The aim of the paper is to examine effects of tax shift on economic growth and provide a direct empirical evidence in the European Union (EU. It is used the Eurostat’s definition to categorize tax burden by economic functions and implicit tax rates of consumption, labour and capital are investigated. First, paper summarizes main development of tax shift in a whole EU till 2014 and followed empirical analysis is based on annual panel data of 22 EU Member States in years 1995–2012 (time span is divided into a pre-crisis and a post-crisis period. Explanatory variables are not examined in individual regressions, but the study uses Generalized Method of Moments applied on dynamic panel data and estimations are based on Arellan-Bond estimator (1991. Results confirm positive and statistically significant impact of consumption taxes and weaker but negative effect of labour taxation on economic growth. In a post-crisis period, findings report raising labour taxes as the strongest and the only significant variable. It suggests that harmful effect of labour taxation is enlarging in a time of unfavorable economic conditions. A tax shift on capital taxation has negative but often statistically insignificant impact on economic growth.

    Full Text Available The aim of the present study is to investigate the effects of different economic determinants on foreign direct investment (FDI for three countries selected from Central Asia namely Armenia, Kyrgyz Republic and Turkmenistan. Secondary data for the period from 1991 to 2009 taken from World Development Indicator (various issues have been utilized. Simple econometric model in log form and the least squares technique have been used. Result found indicates positive effects of market size, official development assistance on FDI and negative effect of inflation on FDI. However, in case of Armenia, the effect of official development assistance on FDI has been found insignificant and such as in case of Kyrgyz Republic, the effect of inflation on FDI has been found insignificant with expected negative sign. Thus, findings of the study recommend that market size and official development assistance needs to be encouraged and inflation needs to be managed in order to achieve higher level of FDI and accelerate the process of economic development.

  13. Transport Infrastructure and Economic Growth: Spatial Effects

    Artyom Gennadyevich Isaev


    Full Text Available The author specifies an empirical framework of neoclassical growth model in order to examine impact of transport infrastructure on economic growth in Russian regions during period of 2000-2013. Two different effects of infrastructure are considered. First, infrastructure is viewed as part of region’s own production function. Second, infrastructure generates spillover effect on adjacent regions’ economic performance which can be negative or positive. Results imply that road infrastructure has a positive influence on regional growth, but sign of railroad infrastructure coefficient depends on whether or not congestion effect is considered. Negative spillover effect is shown to exist in the case of road infrastructure. This apparently means that rapid road infrastructure development in some regions moves mobile factors of production away from adjacent regions retarding their economic development. The spillover effect of railroad infrastructure is significant and negative again only if congestion effect is considered. The results of estimation for the Far East and Baikal Regions separately demonstrate no significant effect of both types of infrastructure for economic performance and negative spillover effect of road infrastructure

  14. The direct economic impact of alternative types of the rural tourism

    Simona Miškolci


    Full Text Available Rural tourism has come to occupy a prominent position in the debate about rural restructuring in all OECD countries, partly because of demand changes which favour rural tourism and partly because rural agencies recognise a need to provide economic activities with potential for growth in a rural economy in which traditional providers of rural employment (such as agriculture have been shedding labour at a rapid rate. Well-designed strategy is essential to its success in impacting on the rural economy. The structures for collaboration and co-operation must be developed and combined with a process of education and training. Co-operative effort must be effective and sustainable. The tourism related businesses should not be isolated from the larger community and its issues.The principal motivation for a community, business or region to serve tourists is generally economic. An individual business is interested primarily in its own revenues and costs, while a community or region is concerned with tourism’s overall contribution to the economy, as well as social, fiscal and environmental impacts. A good understanding of tourism’s economic impacts is therefore important for the tourism industry, government officials, and the community as a whole.The principal objective of the study, that is reported here, was to determine the potential income of farmers from the provision of agro-tourism services. First, the paper reviews selected results of the visitor spending survey in alternative types of rural tourism of the region Southeast (Czech Republic; second the direct economic benefit of the agro-tourism in this region is estimated, and finally, critical factors reducing the effectiveness of agro-tourism as a rural development instrument are drawn.

  15. Determinants of Foreign Direct Investments in Bulgaria and Romania in the Context of Recent Economic Crisis

    Mirel-Daniel Simionescu


    Full Text Available The objective of this paper is to select some relevant macroeconomic determinants for foreign direct investment (FDI in Bulgaria and Romania since the start of the recent economic crisis (2008-2015. Even if the economic recession installed in 2009 in Romania, the foreign investors’ decisions were influenced by the moment of global recession from 2008. A Bayesian approach was proposed, because of the small sample for the variables in analyzed period: FDI as percent of GDP, real GDP rate, unemployment rate, inflation rate, real interest rate, real effective exchange rate index (2010=100 and money demand (M2 as percent of GDP. The estimation results reflected that foreign investors in both countries were attracted by the increase in GDP from a year to another. On the other hand, for Bulgaria the inflation rate was the strongest determinant, indicating the economic stability of the country that made huge efforts in getting one digit inflation rate. In Romania, as expected, the foreign investors were searching for cheap labour force and the increase in unemployment rate attracted more FDI during the crisis period.

  16. Economic Effects of Increased Control Zone Sizes in Conflict Resolution

    Datta, Koushik


    A methodology for estimating the economic effects of different control zone sizes used in conflict resolutions between aircraft is presented in this paper. The methodology is based on estimating the difference in flight times of aircraft with and without the control zone, and converting the difference into a direct operating cost. Using this methodology the effects of increased lateral and vertical control zone sizes are evaluated.




    Full Text Available Foreign Direct Investment (FDI bring an essential contribution to economic growth. They create jobs, optimize the allocation of resources, technology transfer and stimulate trade. Doing business in Romania needs friendly taxation and economic freedom for entrepreneurs, including to foreign investors, creating a favourable economic environment framework by promoting conditions conducive to attracting foreign investors, such as: fair treatment, fair and non-discriminatory manner; protection from illegal situated between kilometeres; the appeal directly to international arbitration, as well as the transformation of Romania into an attractive environment in terms of taxation.

    Carmen BOGHEAN


    Full Text Available The purpose of this analysis is to analyse the connection between foreign direct investments and economic growth in transition economies during a period of increased integration of financial systems in the global financial system. The research focuses on the relationship between foreign direct investments and economic growth during 1970-2013, by means of methods such as the graphic, the regression and the correlation ones. The research findings show that there is a direct and strong connection between the inward financial flows of foreign direct investments and the GDP during the period under analysis in transition economies. In transition economies, a high inward flow of foreign direct investments leads to an increase of the Gross Domestic Product per capita, while a positive development of the standard of living will attract new inward FDI flows, since transition economies are seen as attractive recipients/hosts for foreign direct investments.

  1. Estimating the Direct Medical Economic Burden of Health Care-Associated Infections in Public Tertiary Hospitals in Hubei Province, China.

    Li, Hao; Liu, Xinliang; Cui, Dan; Wang, Quan; Mao, Zongfu; Fang, Liang; Zhang, Furong; Yang, Ping; Wu, Huiling; Ren, Nili; He, Jianyun; Sun, Jing


    This study estimated the attributable direct medical economic burden of health care-associated infections (HAIs) in China. Data were extracted from hospitals' information systems. Inpatient cases with HAIs and non-HAIs were grouped by the propensity score matching (PSM) method. Attributable hospitalization expenditures and length of hospital stay were measured to estimate the direct medical economic burden of HAIs. STATA 12.0 was used to conduct descriptive analysis, bivariate χ 2 test, paired Z test, PSM ( r = 0.25σ, nearest neighbor 1:1 matching), and logistic regress analysis. The statistically significant level was set at .05. The HAIs group had statistically significant higher expenditures and longer hospitalization stay than the non-HAIs group during 2013 to 2015 ( P economic burden of HAIs calls for more effective HAI surveillance and better control with appropriate incentives.

  2. Medium effects in direct reactions

    Karakoc, M; Bertulani, C


    We discuss medium corrections of the nucleon-nucleon (NN) cross sections and their influence on direct reactions at intermediate energies ≳50 MeV/nucleon. The results obtained with free NN cross sections are compared with those obtained with a geometrical treatment of Pauli-blocking and Dirac-Bruecker methods. We show that medium corrections may lead to sizable modifications for collisions at intermediate energies and that they are more pronounced in reactions involving weakly bound nuclei.

  3. The Impact of Foreign Direct Investments on Economic Growth in Romania

    Adrian Petre


    Full Text Available One of the current priority objectives for Romania is the integration into euro zone. To achieve this objective, Romania must record progress on economic growth. Various empirical studies have analyzed the influence of foreign direct investment (FDI on economic growth to see whether investment flows positively influence the economic development. The results revealed that positive connection depends on certain features of the economy at a time. The purpose of this research is to highlight the impact of the FDIs on the Romanian economic development because the debates on capital flows, both in the political and academic environment, associate these flows with a number of benefits for beneficiary states. In order to fulfill the objective of this research is analyzed, mainly, the relationship between foreign direct investment (FDI and gross domestic product (GDP.

    This study examines the impact of volatility of FDI, rather than its level on the economic growth of ASEAN-5 countries. Using bounds testing approach, we show that FDI volatility retards long-run economic growth in Indonesia, Malaysia, the Philippines and Thailand. Our results suggest that the economic growth of Indonesia is the most susceptible to the adverse effect of FDI volatility. These findings, which are robust to different measures of FDI volatility, are of concern in dealing with the...

  5. Foreign Remittances, Foreign Direct Investment, Foreign Imports and Economic Growth in Pakistan: A Time Series Analysis

    Muhammad Tahir


    Full Text Available This empirical research paper focuses on establishing a relationship between external determinants and economic growth of Pakistan economy. Empirical analyses are carried out with time series econometric techniques using data over the period of 1977-2013. The main finding is that external determinants such as foreign remittances, foreign direct investment, and foreign imports matter from a growth perspective. Foreign remittances and foreign direct investment have a significant positive role in the growth process of Pakistan economy. Furthermore, it is found that foreign imports have adversely influenced the economic growth of Pakistan. The study recommends that policy makers shall take appropriate steps to increase the inflow of both foreign remittances and foreign direct investment in order to achieve the long run economic growth.

    The paper examines the nature of China’s economic activities in Africa in three dimensions: merchandise trade, foreign direct investment, and aid. These are three main channels through which China’s presence on the continent affects Africa’s economic growth and development. China’s economic relations with Africa are, to a large extent, driven by Chinese demand for natural resources, especially oil and minerals. It is the most visible in Sino-African trade, where fuels alone account for about ...

  8. Foreign direct investments and their impact on the economic development of Bosnia and Herzegovina

    Susic, I.; Stojanovic-Trivanovic, M.; Susic, M.


    From the perspective of macroeconomic indicators, investment is a significant determinant of economic development in general, as well as the development indicator of economic entities in the micro segment. Investments are an essential element of any economic policy, because their implementation provides a platform not only for economic development, but also are prerequisite for the stability of economic and social trends. Foreign direct investment plays an important role in the financing of the global economy, and it represents the most frequent feature in financing the national economies of developing countries and countries in transition. Demand for foreign investment in the global market is large, and thus the governments have been conducting many activities in order to create a more favorable environment to attract investors. In this paper, special attention was paid to direct investments in financing the economy on a global scale, their importance for the development of the global economy and the impact of foreign direct investment in the economic development of Bosnia and Herzegovina. The major activities, which are necessary to be done to attract investments in the highest possible volume, have been emphasized. With the use of statistical and quantitative analysis, the paper shows that the inflow of foreign capital is one of the basic prerequisite of economic growth acceleration and that the inflow of foreign capital has a positive impact on the economic development of Bosnia and Herzegovina. By monitoring and analyzing the various instruments of foreign capital inflow, with an emphasis on investment in the free zone and a joint venture with foreign investors, it has been clearly pointed out the fact that they have diverse, but proven positive impact on macroeconomic variables in the economy of Bosnia and Herzegovina.

  9. China and India: Openness, Trade and Effects on Economic Growth

    Marelli, Enrico


    Full Text Available The purpose of this paper is to analyse the economic growth of China and India in terms of their integration in the global economy. We begin with a discussion of some stylized facts concerning their recent economic growth, the most significant institutional reforms, with particular reference to trade relations, and their impact on their economic development. We then propose a descriptive analysis of economic growth, opening up of the economies and trade specialisation, by comparing the features and trends of the two countries (by considering trade and foreign direct investment data. We have also estimated some econometric relations between economic growth and trade/openness, with the addition of control variables (such as the gross fixed capital formation. We initially used a panel data model for the two countries, to be estimated with fixed effects; to test for reverse causality, we re-estimated the fixed effects model by 2SLS (with the inclusion of specific instrumental variables. The effect on economic growth (in terms of GDP per capita of our variables of interest - Openness and FDI - remains positive and statistically significant in all specifications, which confirms our findings even if we treat these variables as endogenous variables. The results prove the positive growth effects, for the two countries, of opening up and integrating in the world economy. Note that the robust growth of these two "giants" has contained the initial impact of the recent global crisis and is now sustaining the recovery of the entire world economy. Other policy relevant implications are discussed in the concluding section.

    How does the opportunity to use tax havens influence economic activity in nearby non-haven countries? Analysis of affiliate-level data indicates that American multinational firms use tax haven affiliates to reallocate taxable income away from high-tax jurisdictions and to defer home country taxes on foreign income. Ownership of tax haven affiliates is associated with reduced tax payments by nearby non-haven affiliates, the size of the effect being equivalent to a 20.8 percent tax rate reducti...

  12. The evaluation of Foreign Direct Investments and their impact in the economics of some transition countries: the case of Kosovo

    Halil Kukaj


    Full Text Available The Foreign Direct Investment is suggested to have a positive impact on the economic growth of many countries, especially in the transition countries such as Kosovo. During the last century, the world has witnessed remarkable growth of FDI because they impact positively the overall strategy for economic and social development. This article will provide a general review of the FDIs and will focus on their economic implication on the developing countries and especially in Kosovo and some other Western Balkan countries. The paper will clarify the main causes of failure of foreign direct investments and will revile the importance of indicators that are mainly of institutional nature. It is estimated that FDIs impact the economic development of the host country through two main channels: firstly, FDIs increase the domestic capital and increase the efficiency through the improvement of managerial skills, the transfer of new technology or through the bringing of more effective marketing strategies, innovations and best practices, secondly: the effect of FDIs varies much from the specifications of the country in terms of their capacity to absorb the FDIs, the ability to diversify them and their ability to connect the FDIs with the domestic investments.

  13. Economic effects of restricting carbon dioxide emissions

    Haaparanta, P.; Jerkkola, J.; Pohjola, J.


    The aim of this study is to evaluate the economy-wide effects of reducing CO 2 emissions. NO x and SO 2 emissions can also be included. The policy questions can be approached either by estimating the emission taxes needed to achieve the given levels of emissions or by estimating the level of emissions given the level of taxes. A computable general equilibrium (CGE) is used in this analysis. The general equilibrium models deal with long-run effects, after all markets have equilibrated and all resources are optimally used. They are particularly well-suited to analyze long-run resource allocation, welfare losses and income distribution, beyond the short-run macroeconomic disturbances and business cycle phenomena. As the general equilibrium framework integrates all main economic sectors, the feedbacks and interrelationships between the various sectors are taken into account

  14. Financial analysis of foreign direct investment on economic growth of developing countries

    Raičević Božidar


    Full Text Available The object of the research paper is to perform an empirical analysis of foreign direct investment (FDI influence on economic growth with the aim of establishing factors that will contribute to overcoming the problem. The research results imply that realistic exchange rate, export and import as well as state expenditures are statistically significant for predicting economic growth movement and they have a positive influence on FDI movement. Empirical analysis, contrary to expectations, has shown that FDI, public debt and openness have a negative impact on economic growth in the case of Republic of Serbia. In the following period Serbia has to decrease the share of budget deficit in GDP and control public debt. Serbia has to pay special attention to improving investment environment and encourage export oriented production, whereas finance management and continuation of reform processes are the basis for establishing sustainable development of country, with sustainable use of available resources.

  15. Climate Change Effects on Agriculture: Economic Responses to Biophysical Shocks

    Nelson, Gerald C.; Valin, Hugo; Sands, Ronald D.; Havlik, Petr; Ahammad, Helal; Deryng, Delphine; Elliott, Joshua; Fujimori, Shinichiro; Hasegawa, Tomoko; Heyhoe, Edwina


    Agricultural production is sensitive to weather and thus directly affected by climate change. Plausible estimates of these climate change impacts require combined use of climate, crop, and economic models. Results from previous studies vary substantially due to differences in models, scenarios, and data. This paper is part of a collective effort to systematically integrate these three types of models. We focus on the economic component of the assessment, investigating how nine global economic models of agriculture represent endogenous responses to seven standardized climate change scenarios produced by two climate and five crop models. These responses include adjustments in yields, area, consumption, and international trade. We apply biophysical shocks derived from the Intergovernmental Panel on Climate Change's representative concentration pathway with end-of-century radiative forcing of 8.5 W/m(sup 2). The mean biophysical yield effect with no incremental CO2 fertilization is a 17% reduction globally by 2050 relative to a scenario with unchanging climate. Endogenous economic responses reduce yield loss to 11%, increase area of major crops by 11%, and reduce consumption by 3%. Agricultural production, cropland area, trade, and prices show the greatest degree of variability in response to climate change, and consumption the lowest. The sources of these differences include model structure and specification; in particular, model assumptions about ease of land use conversion, intensification, and trade. This study identifies where models disagree on the relative responses to climate shocks and highlights research activities needed to improve the representation of agricultural adaptation responses to climate change.

  18. Applying Behavioral Economics to Public Health Policy: Illustrative Examples and Promising Directions.

    Matjasko, Jennifer L; Cawley, John H; Baker-Goering, Madeleine M; Yokum, David V


    Behavioral economics provides an empirically informed perspective on how individuals make decisions, including the important realization that even subtle features of the environment can have meaningful impacts on behavior. This commentary provides examples from the literature and recent government initiatives that incorporate concepts from behavioral economics in order to improve health, decision making, and government efficiency. The examples highlight the potential for behavioral economics to improve the effectiveness of public health policy at low cost. Although incorporating insights from behavioral economics into public health policy has the potential to improve population health, its integration into government public health programs and policies requires careful design and continual evaluation of such interventions. Limitations and drawbacks of the approach are discussed. Copyright © 2016 American Journal of Preventive Medicine. All rights reserved.

  19. Direct and indirect economic costs among private-sector employees with osteoarthritis.

    Berger, Ariel; Hartrick, Craig; Edelsberg, John; Sadosky, Alesia; Oster, Gerry


    To estimate direct and indirect economic costs among private-sector employees with osteoarthritis (OA). Using a large US employer benefits database, we identified all employees with evidence of OA during calendar year 2007, and compared their costs of health care and work loss to age-and-sex-matched employees without evidence of OA in that year. Private-sector employees with OA (n = 2399) averaged 62.9 days of absenteeism versus 36.7 days among matched comparators (n = 2399) (P Private-sector employees with OA have higher direct and indirect costs than those without this condition.

  20. Economic Growth, Foreign Direct Investment and CO2 Emissions in China: A Panel Granger Causality Analysis

    Hongfeng Peng


    Full Text Available Using a sample of province-level panel data, this paper investigates the Granger causality associations among economic growth (GDP, foreign direct investment (FDI and CO2 emissions in China. By applying the bootstrap Granger panel causality approach (Kónya, 2006, we consider both cross-sectional dependence and homogeneity of different regions in China. The empirical results support that the causality direction not only works in a single direction either from GDP to FDI (in Yunnan or from FDI to GDP (in Beijing, Neimenggu, Jilin, Shanxi and Gansu, but it also works in both directions (in Henan. Moreover, we document that GDP is Granger-causing CO2 emissions in Neimenggu, Hubei, Guangxi and Gansu while there is bidirectional causality between these two variables in Shanxi. In the end, we identify the unidirectional causality from FDI to CO2 emissions in Beijing, Henan, Guizhou and Shanxi, and the bidirectional causality between FDI and CO2 emissions in Neimenggu.

    Lu, Jingjing; Xu, Aiqiang; Wang, Jian; Zhang, Li; Song, Lizhi; Li, Renpeng; Zhang, Shunxiang; Zhuang, Guihua; Lu, Mingshan


    Although the expenses of liver cirrhosis are covered by a critical illness fund under the current health insurance program in China, the economic burden associated with hepatitis B virus (HBV) related diseases is not well addressed. In order to provide evidence to address the economic disease burden of HBV, we conducted a survey to investigate the direct economic burden of acute and chronic hepatitis B, cirrhosis and liver cancer caused by HBV-related disease. From April 2010 to November 2010, we conducted a survey of inpatients with HBV-related diseases and who were hospitalized for seven or more days in one of the seven tertiary and six secondary hospitals in Shandong, China. Patients were recorded consecutively within a three-to-five month time period from each sampled hospital; an in-person survey was conducted to collect demographic and socio-economic information, as well as direct medical and nonmedical expenses during the last month and last year prior to the current hospitalization. Direct medical costs included total outpatient, inpatient, and self-treatment expenditures; direct nonmedical costs included spending on nutritional supplements, transportation, and nursing. Direct medical costs during the current hospitalization were also obtained from the hospital financial database. The direct economic cost was calculated as the sum of direct medical and nonmedical costs. Our results call for the importance of implementing clinical guideline, improving system accountability, and helping secondary and smaller hospitals to improve efficiency. This has important policy implication for the on-going hospital reform in China. Our data based on inpatients with HBV-related diseases suggested that the direct cost in US dollars for acute hepatitis B, severe hepatitis B, chronic hepatitis B, compensated cirrhosis, decompensated cirrhosis and primary liver cancer was $2954, $10834, $4552, $7400.28, $6936 and $10635, respectively. These costs ranged from 30.72% (for acute

    Full Text Available In the context of globalization and the tightening of relationships among countries, we consider to be important an analysis of the national interest of an economy. The national interest is a complex concept consisting of many interests that occur at several levels, converging towards assuring security, freedom, justice and welfare. The state is the main defender of the national interest. The national interest has as objective the definition of the national development priorities in order to ensure the survival and the prosperity of the country concerned, by following a trend of sustainable development and it is based on several factors, including foreign direct investments. These are a necessity for the development of an economy, especially when national savings do not meet the needs of capital for investments. But in order to serve the national interest, foreign direct investments have to be channeled towards the areas of national interest. After the national interest is defined, there are presented the characteristics of the economic national interest and the ways through which foreign direct investments can support the achievement of the economic interest of an economy. Then, the article highlights a few of the areas toward which foreign direct investments should be directed in Romania in order to sustain the sustainable development of our country.

    Lu, Jing; Xu, Ling; Zhai, Yi; Zhang, Yaoguang; Lyu, Yuebin; Shi, Xiaoming


    To evaluate the status and trend of direct economic burden on cerebrovascular disease, from 1993 to 2008 in China. Using two-step model to calculate the economic cost with related trend of cerebrovascular disease within the population among the over 30-year-olds, from 1993 to 2008. Data was gathered from the National Health Service Surveys Analysis Reports of 1993, 1998, 2003 and 2008, that including both direct outpatient and inpatient cost. There appeared a significant increase on the burden of cerebrovascular diseases in the period of 15 years, with direct economic cost increasing from 8.473 billion to 103.125 billion RMB. In fact, the actual increase was 5.3 times, without the influence of the price. The average annual growth rate was 13.1%, exceeding the rate of total expenditure on health and GDP during the same time span. In addition, the growth rate in 2003-2008 was the fastest, which appeared to be 19.8%. Burden that caused by cerebrovascular disease on individuals and the whole society was heavy which warrented further theoratical and practical studies on it.


    Dementiev N. P.


    Full Text Available The article examines the role of foreign direct investment (FDI in the economic development of Hungary, Poland and the Czech Republic in recent decades. It is shown that the high rates of economic growth achieved by these countries in the pre-crisis years were closely linked to large foreign loans. The governments placed special emphasis on the attraction of FDI in high-tech export industries having very high growth rates (motor vehicles, machinery, equipment, computers, electronics and optics. For this purpose, central banks maintained an undervalued exchange rate of national currencies. As a result, adverse foreign trade balance in each of the three countries has shown a surplus in recent years. Furthermore, the disadvantages of excessive foreign loans are listed: high interest and dividend payments to foreign investors, reduction of national and economic sovereignty. For example, more than half of the Czech economy is under the control of foreign investors. Foreign direct investment in the Russian economy is also briefly discussed. It is shown by comparing the data of the Bank of Russia and the Eurostat that more than half of FDI in Russia is made through so-called special purpose entities (SPE and would be only formally considered a direct investment.

In conclusion, firms were obliged to develop strategies for crisis as a result of their focus on customer, without understanding the customer as an employee. Moreover, strategic changes are not the result of company development, but as a direct effect of economic context. Otherwise, firms do not reflect the strategic communication behavior of their employees. Therefore, such a strategy may not be viable ...

    Full Text Available Migration is one of the oldest phenomena that accompanied the development of human society, sometimes causing clashes between peoples, cultures and civilizations. Recent events or from a not too distant past of Europe show that tensions created by migratory movements often have an impact on political and economic relations between countries, cultures and religions. The Romanian reality shows that after 1989 the resident population experienced a decline. According to the National Institute of Statistics, in the period 1989-2012, Romania's population decreased by about 3.1 million, this reduction being due to both migration phenomenon and negative natural increase of population. Some statistic records also show that the extremes are usually among those who decide to emigrate. On the one hand those who are choosing this path are individuals with low income and a low or medium level of education; on the other hand, we can find the phenomenon of brain drain. It is alarming that among those who choose to emigrate are registered young people able to work, this generating the problem of funding on medium and long term the social services. Starting from such aspects, this paper aims to highlight key issues regarding the intention of emigration of highly educated young people. Using quantitative and qualitative methods the authors of this paper aim to identify some possible causes that may determine the highly educated youth to emigrate, evaluate some possible effects due to this phenomenon and to find proposals to limit the negative effects of demographic decline.

  10. The Relationship between Foreign Direct Investment from Thailand and Export on the Economic Growth of Laos

    Thanet Wattanakul


    Full Text Available This study examines the relationship between Laos’s GDP, Thailand’s direct investment to Laos and Laos’s export to Thailand by using 44 quarters of data from 2005 Q1 to 2015 Q4. All relationships were studied using the vector error correction model (VECM. The results presented long run relationship from Laos’ GDP and Laos’ export to Thailand as well as from Thailand’s direct investment to Laos’s GDP and Laos’s export to Thailand. In the short run, there was only unidirectional relationship from Laos’s GDP to Laos’s exports to Thailand. This study indicates that Laos’s exporters receive benefits from Thailand’s direct investment contribution to accelerate economic growth in the short term. Therefore, Laos’s government should distribute income from the exporters to other economy sectors or spread the types of export goods into a larger range.

  11. Impact of Direct and Indirect Tax on the Nigerian Economic Growth

    Oyebisi Mary Ogundana


    Full Text Available This research examined the direct and indirect impact of taxation on the Nigerian economic growth. This research centered on two major objectives by focusing on the trend of direct and indirect tax and the impact of the Nigerian tax system on the growth of the economy.  The research adopted the descriptive research design.  The secondary source of data was also engaged as this data was from CBN statistical bulletin and the annual reports from 1994-2013. The research also used the ordinary least square regression technique. With the use of E-views 7.1 to analyze the data, the first objective was achieved by using graphical analysis while the second objective used ordinary least square regression analysis. The results reveal that the direct and indirect tax have a positive impact on the economy of Nigeria. Therefore, it is recommended that government should take advantage of taxation and promote tax system in Nigeria.

  13. Truth Behind Economic Performance, Natural Resources and Attracting Foreign Direct Investment

    Arthelo P. Palma


    Full Text Available Using a preliminary investigation and analysis on the latest data on GDP (Gross Domestic Product performance, GOI (Global Opportunity Index, Vulnerability Score, Readiness Score, and the number of resources of economic importance, exploratory or preliminary SEM (structural equation modelling was prompted on the recent available data of the 131 countries (n=131. The model was robust, addressing concerns about multivariate assumptions and other measures on the goodness of fit. It was found that the number of natural resources of economic importance plays a large role in the GDP performance. Thus, the preliminary symptom of Dutch disease continues to manifest for as long as each country aims for development, with their resources as ultimate enticing factors for foreign direct investment (FDI. In addition, economic growth is so far observed to be associated with the vulnerability of the country to climate change. Finally, economic growth was found to be linked to the negative impacts argued by the dependency theory. Implication on governance was discussed.

  14. Limits to Economic Growth: Why Direct Investments Are Needed to Address Child Undernutrition in India.

    Subramanian, S V; Subramanyam, Malavika A


    About two of every five undernourished young children of the world live in India. These high levels of child undernutrition have persisted in India for several years, even in its relatively well-developed states. Moreover, this pattern was observed during a period of rapid economic growth. Evidence from India and other developing countries suggests that economic growth has little to no impact on reducing child undernutrition. We argue that a growth-mediated strategy is unlikely to be effective in tackling child undernutrition unless growth is pro-poor and leads to investment in programs addressing the root causes of this persistent challenge.

  15. Greenlining. Economic and Environmental Effects of Government Facilitated Lending to Sustainable Economic Activities in the Netherlands

    Scholtens, B.


    This paper analyzes the economic and environmental impact of a policy instrument that is related to the tax deductibility of interest returns and dividend yields from specified 'green' projects. We investigate this so-called 'Green Project Facility' in the Netherlands during 1995-1999. We analyze the effect on taxes, economic growth, employment, as well as on the emission of a number of gases and on solid waste production. We find that the economic effects in general are positive. However, the environmental effects are quite mixed. It is concluded that the policy instrument could be used much more effective

  19. An Assessment of Direct and Indirect Economic Losses of Climatic Extreme Events

    Otto, C.; Willner, S. N.; Wenz, L.; Levermann, A.


    Risk of extreme weather events like storms, heat extremes, and floods has already risen due to anthropogenic climate change and is likely to increase further under future global warming. Additionally, the structure of the global economy has changed importantly in the last decades. In the process of globalization, local economies have become more and more interwoven forming a complex network. Together with a trend towards lean production, this has resulted in a strong dependency of local manufacturers on global supply and value added chains, which may render the economic network more vulnerable to climatic extremes; outages of local manufacturers trigger indirect losses, which spread along supply chains and can even outstrip direct losses. Accordingly, in a comprehensive climate risk assessment these inter-linkages should be considered. Here, we present acclimate, an agent based dynamic damage propagation model. Its agents are production and consumption sites, which are interlinked by economic flows accounting for the complexity as well as the heterogeneity of the global supply network. Assessing the economic response on the timescale of the adverse event, the model permits to study temporal and spatial evolution of indirect production losses during the disaster and in the subsequent recovery phase of the economy. In this study, we focus on the dynamic economic resilience defined here as the ratio of direct to total losses. This implies that the resilience of the system under consideration is low if the high indirect losses are high. We find and assess a nonlinear dependence of the resilience on the disaster size. Further, we analyze the influence of the network structure upon resilience and discuss the potential of warehousing as an adaptation option.

  3. Effect of Component Failures on Economics of Distributed Photovoltaic Systems

    Lubin, Barry T. [Univ. of Hartford, West Hartford, CT (United States)


    for both. Some societal benefits associated with financial benefits to the utility of having a distributed generation capacity that is not fossil-fuel based have been included into the economic models. Also included and quantified in the models are several benefits to society more generally: job creation and some estimates of benefits from avoiding greenhouse emissions. PV system failures result in a lowering of the economic values of a grid-connected system, but this turned out to be a surprisingly small effect on the overall economics. The most significant benefit noted resulted from including the societal benefits accrued to the utility. This provided a marked increase in the valuations of the array and made the overall value proposition a financially attractive one, in that net present values exceeded installation costs. These results indicate that the Department of Energy and state regulatory bodies should consider focusing on societal benefits that create economic value for the utility, confirm these quantitative values, and work to have them accepted by the utilities and reflected in the rate structures for power obtained from grid-connected arrays. Understanding and applying the economic benefits evident in this work can significantly improve the business case for grid-connected PV installations. This work also indicates that the societal benefits to the population are real and defensible, but not nearly as easy to justify in a business case as are the benefits that accrue directly to the utility.

  4. The economics of reprocessing versus direct disposal of spent nuclear fuel

    Bunn, M.; Holdren, J.P.; Fetter, S.; Zwaan, B. van der


    The economics of reprocessing versus direct disposal of spent nuclear fuel are assessed. The break-even uranium price at which reprocessing spent nuclear fuel from existing light water reactors (LWRs) and recycling the resulting plutonium and uranium in LWRs would become economic is estimated for a wide range of reprocessing prices and other fuel cycle costs and parameters. The contribution of each fuel cycle option to the cost of electricity is also estimated. A similar analysis is performed for the breakeven uranium price at which deploying fast neutron reactors (FRs) would become competitive compared with a once-through fuel cycle in LWRs, for a range of differences in capital cost between LWRs and FRs. Available information about reprocessing prices and various other fuel cycle costs and input parameters are reviewed, as well as the quantities of uranium likely to be recoverable worldwide at a range of different possible future prices. It is concluded that the once-through fuel cycle is likely to remain significantly cheaper than reprocessing and recycling in either LWRs or FRs for at least the next 50 years. Finally, there is a discussion of how scarce and expensive repository space would have to become before separation and transmutation would be economically attractive. (author)

  5. Foreign direct investment with regard to the economic growth of the Japanese economy

    Milan Palát


    Full Text Available Foreign direct investment presents an indivisible part of the global economy and a major catalyst to development. The paper stresses out the importance of FDI in boosting the growth of the nation’s economy and is aimed at assessing the flow of inward FDI into Japan in the frame of the economic development of the country. Many studies reflected the superior managerial efficiency and productivity of foreign business companies operating in Japan and this is considered to be an asset of inward FDI into Japan. From the beginning of the reference period (with an exception of last two decades the ratio of FDI on gross domestic product in Japan remained quite stable. This economy witnessed augmented FDI flows in the 1990s but current economic situation aggravated by the global financial and economic crisis differs significantly from the development in previous years. A fitted developmental series using a logarithmic polynomial indicate the described trend of FDI in Japan. Based on results of methods of regression and correlation analysis (including testing the statistical significance, the correlation is evident between FDI and gross domestic product in the monitored country and the existence of a growth impact of FDI can be thus accepted.




    Full Text Available n over three decades and a half of spectacular economic growth – starting in 1979 with the launch of reform processes and with the dynamic mutations from an autarchic to a global model – the introduction and implementation of the policies targeting the use and attraction of foreign direct investment (FDI represented an exceptionally important stage in China’s history of international “openness,” playing an active role in the promotion, support and enhancement of its economic development. The aim of this article is to outline China’s sinuous investment path, from the autarchic pattern followed by the stage of economic openness characterised by the application of the “open doors” policy and up to the rethinking of the development paradigm and the country’s affirmation on the market as a new powerhouse in the global economy. Our research also aims to outline the implications that all these stages had on China’s current position of world leader in terms of inward FDI. As such, by means of comparative, quantitative and qualitative analyses, we will examine the evolution in time and the external impact of policies regarding the attraction of FDI, as well as the strategy aiming at incentivising Chinese outward investment – a relatively recent phenomenon – and the related support measures, in order to identify the country’s current development stage and its position in the global landscape, as well the possible challenges that China might face in the future.


    Bunn, Matthew; Fetter, Steve; Holdren, John P.; Zwaan, Bob van der


    This report assesses the economics of reprocessing versus direct disposal of spent nuclear fuel. The breakeven uranium price at which reprocessing spent nuclear fuel from existing light-water reactors (LWRs) and recycling the resulting plutonium and uranium in LWRs would become economic is assessed, using central estimates of the costs of different elements of the nuclear fuel cycle (and other fuel cycle input parameters), for a wide range of range of potential reprocessing prices. Sensitivity analysis is performed, showing that the conclusions reached are robust across a wide range of input parameters. The contribution of direct disposal or reprocessing and recycling to electricity cost is also assessed. The choice of particular central estimates and ranges for the input parameters of the fuel cycle model is justified through a review of the relevant literature. The impact of different fuel cycle approaches on the volume needed for geologic repositories is briefly discussed, as are the issues surrounding the possibility of performing separations and transmutation on spent nuclear fuel to reduce the need for additional repositories. A similar analysis is then performed of the breakeven uranium price at which deploying fast neutron breeder reactors would become competitive compared with a once-through fuel cycle in LWRs, for a range of possible differences in capital cost between LWRs and fast neutron reactors. Sensitivity analysis is again provided, as are an analysis of the contribution to electricity cost, and a justification of the choices of central estimates and ranges for the input parameters. The equations used in the economic model are derived and explained in an appendix. Another appendix assesses the quantities of uranium likely to be recoverable worldwide in the future at a range of different possible future prices

  8. Economic reform in Vietnam - the role of foreign direct investment and trade policy

    Tran, D.L.


    Vietnam was one of the five poorest countries in the world in the 1980's. Since then, Vietnam has adopted a market economic policy, and she has made substantial economic progress. In the last 10 years Meanwhile Vietnam's per capita income has increased by 3 times, the volume of export doubled very two years, and the inflation rate was reduced to 4.5 % in 1997 from 775 % in 1986. The GDP also has increased, the exchange rate with the US$ was stabilized and foreign direct investment (FDI) and trade has increased. There was about US$35 billion were invested by the foreign investors between 1987 to the middle of June 1998. However, the current crisis in the economies of Southeast Asian countries has put pressure on Vietnam to rethink seriously her future reform program with respect to stabilization and sustainable current economic policies. Since FDI is an imperative for the development of a country like Vietnam, it is necessary to use this capital very careful for her economy. Thus, the main objective of this dissertation is to study the role of FDI in the development of Vietnam. To examine this objective, various investigations were made, especially focusing on development dimensions such as reforming state enterprises, foreign trade policy, foreign investment and so on. Therefore, in the future, FDI and privatization policies should be strengthened to maintain and create an international market. Moreover, there are some major reforms required to transform the state sector into a private sector with appropriate policy measures, such as improving management of financial companies, developing the agricultural sector and minimizing bureaucracy and red tapism of the government. This dissertation provides a set of recommendations how to strengthen Vietnams economic and market situation in the 21st century. (author)

  9. Economic Evaluation of a Patient-Directed Music Intervention for ICU Patients Receiving Mechanical Ventilatory Support.

    Chlan, Linda L; Heiderscheit, Annette; Skaar, Debra J; Neidecker, Marjorie V


    Music intervention has been shown to reduce anxiety and sedative exposure among mechanically ventilated patients. Whether music intervention reduces ICU costs is not known. The aim of this study was to examine ICU costs for patients receiving a patient-directed music intervention compared with patients who received usual ICU care. A cost-effectiveness analysis from the hospital perspective was conducted to determine if patient-directed music intervention was cost-effective in improving patient-reported anxiety. Cost savings were also evaluated. One-way and probabilistic sensitivity analyses determined the influence of input variation on the cost-effectiveness. Midwestern ICUs. Adult ICU patients from a parent clinical trial receiving mechanical ventilatory support. Patients receiving the experimental patient-directed music intervention received a MP3 player, noise-canceling headphones, and music tailored to individual preferences by a music therapist. The base case cost-effectiveness analysis estimated patient-directed music intervention reduced anxiety by 19 points on the Visual Analogue Scale-Anxiety with a reduction in cost of $2,322/patient compared with usual ICU care, resulting in patient-directed music dominance. The probabilistic cost-effectiveness analysis found that average patient-directed music intervention costs were $2,155 less than usual ICU care and projected that cost saving is achieved in 70% of 1,000 iterations. Based on break-even analyses, cost saving is achieved if the per-patient cost of patient-directed music intervention remains below $2,651, a value eight times the base case of $329. Patient-directed music intervention is cost-effective for reducing anxiety in mechanically ventilated ICU patients.

  10. Potential economic effects of climate change on Finnish agriculture



    Full Text Available In the assessment of the economic effects of climate change, changes in returns and costs have to be taken into consideration. Changes in returns are mainly caused by changes in the yield level. Costs are determined by various factors. Harvesting conditions may improve as the temperatures are higher. However, an increasing need for disease and pest control results in higher costs. Various extensive studies have indicated that rising temperatures with the CO2 fertilizing effect increase the crop potential in Finland. From the economic point of view an increase in yield level is highly significant, because the increase in costs remains quite small. A 10% increase in the yield level raises the farm income by about 6%. Because agriculture is supported in many ways either directly or indirectly, the rise in income level may be offset by lowering the support. Consequently, farmers may not benefit from an increase in the yield level, but the benefit will go to the state economy. However, an increase in the yield level resulting from rising temperatures is advantageous to the national economy, regardless of whether the benefit goes to the farmers or to the state.;

    Full Text Available The purpose of this study is to investigate whether there is a relationship among foreign direct investment and some of the macroeconomics variables in Turkey. For this purpose for the period of 1970-2006, the relationships among foreign direct investment and GDP, labour cost, real exchange rate, openness and foreign trade deficit are econometrically analyzed by employing multivariate cointegration analysis and error correction model. According to the results, FDI is positively effected by GDP and openness, and negatively by labour cost, real exchange rate ve foreign trade deficit variables. Morever, bi-directional causality is observed among FDI and GDP and real exchange rate.

  19. Cognitive Capitalism: Economic Freedom Moderates the Effects of Intellectual and Average Classes on Economic Productivity.

    Coyle, Thomas R; Rindermann, Heiner; Hancock, Dale


    Cognitive ability stimulates economic productivity. However, the effects of cognitive ability may be stronger in free and open economies, where competition rewards merit and achievement. To test this hypothesis, ability levels of intellectual classes (top 5%) and average classes (country averages) were estimated using international student assessments (Programme for International Student Assessment; Trends in International Mathematics and Science Study; and Progress in International Reading Literacy Study) (N = 99 countries). The ability levels were correlated with indicators of economic freedom (Fraser Institute), scientific achievement (patent rates), innovation (Global Innovation Index), competitiveness (Global Competitiveness Index), and wealth (gross domestic product). Ability levels of intellectual and average classes strongly predicted all economic criteria. In addition, economic freedom moderated the effects of cognitive ability (for both classes), with stronger effects at higher levels of freedom. Effects were particularly robust for scientific achievements when the full range of freedom was analyzed. The results support cognitive capitalism theory: cognitive ability stimulates economic productivity, and its effects are enhanced by economic freedom. © The Author(s) 2016.

  2. Economic regionalization and choice of strategic development directions of municipalities of the Republic of Tatarstan

    Panasyuk, M. V.


    This paper shows the results of economic regionalization and zoning of the Republic of Tatarstan, conducted in 2017. The latest experience of economic regionalization and zoning of the Republic of Tatarstan in 2007 - 2015 is exposed. The economic regionalization problem is solved on the basis of new method and algorithm that uses quantitative measures which characterize spatial and economic features of generated economic regions including their internal and average connectivity, homogeneity, compactness, socio-economic development level and life quality of the population. Three nodal and one homogeneous economic region in the Republic of Tatarstan were identified. The results of economic zoning within homogeneous economic region led to the conclusion about two existing economic zones. They have the potential for developing new economic growth pole and three economic centers - growth points with specialization on agro-industrial sector.

    Full Text Available European settler mortality has been proposed as an instrument to predict the causal effect of colonial institutions on differences in economic development. We examine the relationship between mortality, temperature, and economic development in former European colonies in Asia, Africa, and the Americas. We find that (i European settler mortality rates increased with regional temperatures and (ii economic output decreased with regional temperatures. Conditioning on the continent of settlement and accounting for colonies that were not independent as of 1900 undermines the causal effect of colonial institutions on comparative economic development. Our findings run counter to the institutions hypothesis of economic development, showing instead that geography affected both historic mortality rates and present-day economic output.

  4. Economic effect of fusion in energy market. Economic impact of fusion deployment in energy market

    Konishi, Satoshi


    Energy model analysis estimates the significant contribution of fusion in the latter half of the century under the global environment constraints if it will be successfully developed and introduced into the market. The total possible economical impact of fusion is investigated from the aspect of energy cost savings, sales, and its effects on Gross Domestic Products. Considerable economical possibility will be found in the markets for fusion related devices, of currently developing countries, and for synthesized fuel. The value of fusion development could be evaluated from these possible economic impact in comparison with its necessary investment. (author)

  6. Implementation of Electricity Business Competition Framework with Economic Dispatch Direct Method

    Yusra Sabri


    Full Text Available Technically, electricity business under competition structure is more complex than that of vertically integrated one. The main prolems here are how to create an applicable competition framework and to solve electric calculations very quickly to obtain an optimal energi pricing, cost of losses, congestion and transportation costs by less than 15 minutes. This paper proposes a competition framework with the electric calculations, where a bilateral contract has been accommodated. Optimal energy price in the paper is calculated based on direct method of economic dispatch to obtain the result very quickly. The proposed method has been simulated to a 4-bus system. The simulation results show that the method works well and complies with the expectation. Therefore, electric power business under competition structure can be well realized by the proposed method.

  7. Subtask 3.3 - Feasibility of Direct Coal Liquefaction in the Modern Economic Climate

    Benjamin Oster; Joshua Strege; Marc Kurz; Anthony Snyder; Melanie Jensen


    Coal liquefaction provides an alternative to petroleum for the production of liquid hydrocarbon-based fuels. There are two main processes to liquefy coal: direct coal liquefaction (DCL) and indirect coal liquefaction (ICL). Because ICL has been demonstrated to a greater extent than DCL, ICL may be viewed as the lower-risk option when it comes to building a coal liquefaction facility. However, a closer look, based on conversion efficiencies and economics, is necessary to determine the optimal technology. This report summarizes historical DCL efforts in the United States, describes the technical challenges facing DCL, overviews Shenhua's current DCL project in China, provides a DCL conceptual cost estimate based on a literature review, and compares the carbon dioxide emissions from a DCL facility to those from an ICL facility.

  8. Behavioral economics perspective on foreign direct investment in emerging markets: The case on Bosnia and Herzegovina

    Amra Halaba


    Full Text Available The growing field of behavioral economics (BE has revolutionized the way we look at economic behavior at micro and macro levels. Importance of foreign direct investment (FDI appeals for analysis of decisions made regarding it to be assessed from expanding view of BE. This research provides overview of previous studies and focuses on the case of Bosnia and Herzegovina (B&H as representative of emerging markets to investigate motivations for investing into this country by temporarily present foreign companies. Empirical analysis was based on the questionnaire that was disseminated among foreign investors to B&H. Questionnaire contained motivations for investing in B&H, where examined motivation factors were divided in two groups; namely irrational and rational ones. Choice of methodology was narrowed due to moderate sample size, but consisting of quality the sample members. In order to analyze data, descriptive statistics, correlation analysis and regression analysis were used. By regressing two groups of predictors on annual amount of foreign investments to B&H, it was shown that the highest motivation for investing was business instinct.


    Suzana Djordjevic


    Full Text Available In recent years, Croatia was interesting to investors in attracting foreign direct investment. One of the objectives of this research was to deal with their negative effects. Most of invested capital was invested in brownfield investments, i.e. in taking over the ownership share of companies through privatization. Consequently, revenues were spent to settle financial debts and not on the growth and development of competitiveness. According to economic theory, foreign direct investments have a positive impact on the economic growth of the recipient country. This paper attempts to answer the question: ‘Is the economic theory confirmed in the Croatian case?’ The aim is to analyse the impact of foreign direct investments on the economic growth of Croatia in the period from 1999 to 2014. The paper analyses the impact that direct foreign investments had on the unemployment rate, GDP per capita and export using the model of linear regression.

  10. Biomass direct-fired power generation system in China: An integrated energy, GHG emissions, and economic evaluation for Salix

    Wang, Changbo; Zhang, Lixiao; Chang, Yuan; Pang, Mingyue


    To gain a better understanding of the options of biomass power generation in China, this study presented an integrated energy, environmental, and economic evaluation for Salix in China, and a typical Salix direct-fired power generation system (SDPGS) in Inner Mongolia was selected for case study. A tiered hybrid life cycle assessment (LCA) model was developed to calculate the “planting-to-wire” (PTW) energy consumption, greenhouse gas (GHG) emissions, and economic cost and profit of the SDPGS, including feedstock cultivation, power plant construction and operation, and on-grid price with/without government subsidies. The results show that the PTW energy consumption and GHG emissions of Salix are 0.8 MJ/kWh and 114 g CO 2 -eq/kWh, respectively, indicating an energy payback time (EPBT) of 3.2 years. The SDPGS is not economically feasible without government subsidies. The PTW costs are dominated by feedstock cultivation. The energy saving and GHG mitigation benefits are still robust, even when the power plant runs at only 60% design capacity. For future development of biomass power in China, scientific planning is necessary to guarantee a sufficient feedstock supply. In addition, technology progress, mature industrial chains, and reasonable price setting policy are required to enable potential energy and environmental advantages of biomass power moving forward. -- Highlights: •A hybrid LCA model was used to evaluate overall performance of the SDPGS. •On-site processes dominate the “planting-to-wire” footprints. •The energy saving and GHG mitigation benefits of the SDPGS are robust. •The economic profit of the SDPGS is feeble without government subsidies. •Generating efficiency promotion has a comprehensive positive effect on the system

  13. Implementation and adaptation of a macro-scale methodology to calculate direct economic losses

    Natho, Stephanie; Thieken, Annegret


    As one of the 195 member countries of the United Nations, Germany signed the Sendai Framework for Disaster Risk Reduction 2015-2030 (SFDRR). With this, though voluntary and non-binding, Germany agreed to report on achievements to reduce disaster impacts. Among other targets, the SFDRR aims at reducing direct economic losses in relation to the global gross domestic product by 2030 - but how to measure this without a standardized approach? The United Nations Office for Disaster Risk Reduction (UNISDR) has hence proposed a methodology to estimate direct economic losses per event and country on the basis of the number of damaged or destroyed items in different sectors. The method bases on experiences from developing countries. However, its applicability in industrial countries has not been investigated so far. Therefore, this study presents the first implementation of this approach in Germany to test its applicability for the costliest natural hazards and suggests adaptations. The approach proposed by UNISDR considers assets in the sectors agriculture, industry, commerce, housing, and infrastructure by considering roads, medical and educational facilities. The asset values are estimated on the basis of sector and event specific number of affected items, sector specific mean sizes per item, their standardized construction costs per square meter and a loss ratio of 25%. The methodology was tested for the three costliest natural hazard types in Germany, i.e. floods, storms and hail storms, considering 13 case studies on the federal or state scale between 1984 and 2016. Not any complete calculation of all sectors necessary to describe the total direct economic loss was possible due to incomplete documentation. Therefore, the method was tested sector-wise. Three new modules were developed to better adapt this methodology to German conditions covering private transport (cars), forestry and paved roads. Unpaved roads in contrast were integrated into the agricultural and

  15. Effects of Greenhouse Gas Emissions on World Agriculture, Food Consumption, and Economic Welfare

    Darwin, R.


    Because of many uncertainties, quantitative estimates of agriculturally related economic impacts of greenhouse gas emissions are often given low confidence. A major source of uncertainty is our inability to accurately project future changes in economic activity, emissions, and climate. This paper focuses on two issues. First, to what extent do variable projections of climate generate uncertainty in agriculturally related economic impacts? Second, to what extent do agriculturally related economic impacts of greenhouse gas emissions depend on economic conditions at the time of impacts? Results indicate that uncertainty due to variable projections of climate is fairly large for most of the economic effects evaluated in this analysis. Results also indicate that economic conditions at the time of impact influence the direction and size of as well as the confidence in the economic effects of identical projections of greenhouse gas impacts. The economic variable that behaves most consistently in this analysis is world crop production. Increases in mean global temperature, for example, cause world crop production to decrease on average under both 1990 and improved economic conditions and in both instances the confidence with respect to variable projections of climate is medium (e.g., 67%) or greater. In addition and as expected, CO2 fertilization causes world crop production to increase on average under 1990 and improved economic conditions. These results suggest that crop production may be a fairly robust indicator of the potential impacts of greenhouse gas emissions. A somewhat unexpected finding is that improved economic conditions are not necessarily a panacea to potential greenhouse-gas-induced damages, particularly at the region level. In fact, in some regions, impacts of climate change or CO2 fertilization that are beneficial under current economic conditions may be detrimental under improved economic conditions (relative to the new economic base).

  16. Economic valuation of selected direct and indirect use values of the Makgadikgadi wetland system, Botswana

    Setlhogile, Tshepo; Arntzen, Jaap; Mabiza, Collin; Mano, Reneth

    Economic valuation of wetlands aims to investigate public preferences for changes in the state of the wetland and the natural resources it constitutes in monetary terms. It provides a means of quantifying the direct and indirect benefits that people derive from wetlands. In addition, it informs management planning and practice about resource options, optimal allocation and also provides information for conservation of the resource. The Makgadikgadi wetland is a unique system that mostly consists of dry pans during most of the year. This study aimed at estimating the value of groundwater recharge and community-based natural resource management (CBNRM) activities within the Makgadikgadi wetland and how these goods and services contribute to the local and national economy. The study used the Total Economic Valuation approach, which considers both the direct and indirect use values of the resource. In essence, the study concentrated on one direct use value (use of resources through CBNRM) and one indirect use value (groundwater recharge). With regard to CBNRM, three community-based organisations (CBOs) were selected for the study and static and dynamic cost-benefit models for these CBOs were developed. The groundwater recharge value was largely determined through desktop review and interviews with stakeholders. The results indicate a small positive contribution of CBOs towards the economy of Botswana and a high potential for communities to derive substantial benefits from the projects because currently benefits realised by communities are limited. CBOs involved in joint venture partnerships with tourism and hunting enterprises benefit more from utilising the wetland’s resources. Groundwater recharge often occurs in areas away from the physical location of the wetland and may not be easily attributable to the wetland. However, the study assessed the value taking into consideration the various sectors which rely on the groundwater resource. The groundwater recharge

  17. The effect of enforcing some direct tax law

    Hassan Ghodrati


    Full Text Available Regarding to the role of tax in the economy as the most stable and constant source of income and also due to the fact that there was no success in achieving fiscal goals by the government during its economic and developmental programs, paying attention to and making effort in this domain is regarded as a necessity in any country. The purpose of this study is to evaluate the effect of enforcing Article 181 of Direct Tax Law on extent of taxpayers’ satisfaction, increase of trust, increase of tax compliance or decrease of tax evasion in Isfahan, Iran. The present study consists of a main hypothesis and four sub-hypotheses. Data were collected from 100 companies regarding their performance during 200 years. Article 181 of Direct Tax Code was implemented upon these companies over the period 2006-2011. Hypotheses of the study were evaluated. The results of the study, in survey and post-event pivot, showed that enforcing Article 181 of Direct Tax Law in Isfahan was effective. However, its effect was not significant regarding increase of taxpayers’ familiarity and acquaintance with Tax Office and its functions in Isfahan; it increased tax compliance, decreased tax evasion by the taxpayers, increased taxpayers’ satisfaction and helped them trust on Tax Office and its performance.

  18. Regulation of international energy markets: Economic effects of political actions

    Shcherbakova, Anastasia V.

    Recent increases in volatility of energy prices have led many governments to reevaluate their regard of national energy reserves and reconsider future exploration, production, and consumption patterns. The flurry of activity that has been generated by such price volatility has included large-scale nationalizations of energy sectors, unilateral renegotiations of foreign energy development contracts, and expropriations of resources from foreign energy firms on one hand, and on the other hand more rapid energy sector liberalization, intensified search for and development of renewable fuels and technologies, and development of incentives for increased energy efficiency and conservation. The aim of this dissertation is to examine and quantify the extent of positive and negative effects that have resulted from some of these activities. The first chapter focuses on quantifying the effect that nationalistic sentiment has had on economic attractiveness of energy sectors during the decade prior to the recent global economic crisis, as measured by foreign direct investment (FDI) inflows. Empirical results demonstrate that both political and economic conditions play an important role in investors' decisions. A combination of investment friendliness, corruption levels, and democracy all help to explain the trends in energy-sector investment levels over time in my sample countries, although differences in the types of corruption existing in these nations do not. Investment levels, in turn, appear to influence future levels of oil production, underscoring the significance of good investment policies for future success of energy sectors. Chapter two considers the response of energy stock prices to severe regulatory actions. It employs an event study framework to examine causal effects of critical informational announcements (i.e. events of expropriation and nationalization) on daily returns and cumulative losses in firm value of energy corporations. Results show that a firm

    Full Text Available The internationalization and globalization of economical problems, industrial manufacturing, and the movement of financial capital, determine the investment activities to become a global one, with implications for all the national and world wide economies. As a result, the foreign direct investments, throughout their economical constitution and substance, form a part of the economical relationships and international cooperation, which bring an essential contribution to the economical growth, creating work places, optimize the allocation of resources, enabling technology transfer and stimulate trading. Foreign Direct Investments have presently become the most important source of external funding for all the countries, regardless of their level of development. This kind of investments proved to be a more stable and used source of funding than the portfolio investments or the bank loans, as they are less affected by the financial crisis. Against this background, global direct financial investments flows remain one of the main manifestations of globalization, which is easily demonstrated if we reflect on the fact that currently over 50% of everything that happens in the world, be it product or services, is carried out by subsidiaries of transnational corporations, namely companies resulting from direct financial investments. It is estimated that the volume, structure and geographical distribution of foreign direct investments will be "patterned" in the proportion of 50% by the international economic situation, the implications of the crisis on the global financial system.

  1. Economism

    P. Simons


    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.

From this aspect, it is aimed at this research that to evaluate the effects of the economic freedoms on the long termed economic growth performances and income level differences of EU and COMCEC countries which have different statuses in terms of economic freedoms and income level indicators. It is determined at the end of the study that the economic freedoms have a positive and statistically significant effect on the economic growth of EU countries in investigation period, on the other hand, these freedoms have not any effect on the economic growth of COMCEC countries. Moreover, the existence of a one-way causality relation operates from economic freedoms to the economic growth in EU countries is specified while there is any causality link found between these freedoms and the economic growth for the countries in COMCEC group. All these results indicate that also the economic freedoms besides the physical human capital accumulation, in other words, whether the EU and COMCEC countries have a market economy adopts outward-oriented liberal fiscal policies plays a major role in differentiating the income levels or the economic growth performances.

  4. Care-Seeking Patterns and Direct Economic Burden of Injuries in Bangladesh.

    Alfonso, Natalia Y; Alonge, Olakunle; Hoque, Dewan Md Emdadul; Baset, Kamran Ul; Hyder, Adnan A; Bishai, David


    This study provides a comprehensive review of the care-seeking patterns and direct economic burden of injuries from the victims' perspective in rural Bangladesh using a 2013 household survey covering 1.17 million people. Descriptive statistics and bivariate analyses were used to derive rates and test the association between variables. An analytic model was used to estimate total injury out-of-pocket (OOP) payments and a multivariate probit regression model assessed the relationship between financial distress and injury type. Results show non-fatal injuries occur to 1 in 5 people in our sample per year. With average household size of 4.5 in Bangladesh--every household has an injury every year. Most non-fatally injured patients sought healthcare from drug sellers. Less than half of fatal injuries sought healthcare and half of those with care were hospitalized. Average OOP payments varied significantly (range: $8-$830) by injury type and outcome (fatal vs. non-fatal). Total injury OOP expenditure was $$355,795 and $5000 for non-fatal and fatal injuries, respectively, per 100,000 people. The majority of household heads with injuries reported financial distress. This study can inform injury prevention advocates on disparities in healthcare usage, OOP costs and financial distress. Reallocation of resources to the most at risk populations can accelerate reduction of preventable injuries and prevent injury related catastrophic payments and impoverishment.

  5. Effects of Economic and Social Implications of Tourism on Economic Flows

    Șerban Comănescu Adrian


    Full Text Available The development of tourism at national level can also be influenced by the policies of other economic sectors or activities with which tourism interacts to a greater or lesser extent, such as: transport infrastructure, environmental protection, educational programs, land use planning, regional plan. The objective of this paper is to analyze the effects of economic and social implications of Romanian tourism on economic flows and tourism in balance of payments and investment position of Romania. Romania's receiving tourism is little represented in the tourist traffic, and the receipts in the field relative to GDP represent a smaller share even than the traditional EU tourist-issuing countries such as the UK, Germany or the Scandinavian countries.

  6. Phenylketonuria: Direct and indirect effects of phenylalanine.

    Schlegel, Gudrun; Scholz, Ralf; Ullrich, Kurt; Santer, René; Rune, Gabriele M


    High phenylalanine concentrations in the brain due to dysfunctional phenylalanine hydroxylase (Pah) are considered to account for mental retardation in phenylketonuria (PKU). In this study, we treated hippocampal cultures with the amino acid in order to determine the role of elevated levels of phenylalanine in PKU-related mental retardation. Synapse density and dendritic length were dramatically reduced in hippocampal cultures treated with phenylalanine. Changes in cofilin expression and phosphorylation status, which were restored by NMDA, as well as reduced activation of the small GTPase Rac1, likely underlie these structural alterations. In the Pah(enu2) mouse, which carries a mutated Pah gene, we previously found higher synaptic density due to delayed synaptic pruning in response to insufficient microglia function. Microglia activity and C3 complement expression, both of which were reduced in the Pah(enu2) mouse, however, were unaffected in hippocampal cultures treated with phenylalanine. The lack of a direct effect of phenylalanine on microglia is the key to the opposite effects regarding synapse stability in vitro and in the Pah(enu2) mouse. Judging from our data, it appears that another player is required for the inactivation of microglia in the Pah(enu2) mouse, rather than high concentrations of phenylalanine alone. Altogether, the data underscore the necessity of a lifelong phenylalanine-restricted diet. Copyright © 2016 Elsevier Inc. All rights reserved.

    Roxana Gabriela Hodorogel


    Full Text Available Romania has ended a high growth cycle. The world economic crisis is worsening with every passing day and Romania increasingly feels the effects of this economic downturn. The sector of small and medium enterprises (SMEs is the most dynamic in the Romanian economy, but it will also be one of the first to be hit by the global financial crisis the ripples of which have reached Romania as well. SMEs are now considered the most sensitive sector and worst affected by the economic climate. The economic crisis has prompted the member states of the European Union, too, to adopt packages of measures to counteract the effect of the crisis. Here below I will exemplify with the cases of Romania, the Italian Republic, the Federal Republic of Germany, the Slovak Republic and the Republic of Hungary.

  8. Direct convertor based upon space charge effects

    Gitomer, S.J.


    A device capable of converting directly the kinetic energy of charged particles into electrical energy is considered. The device differs from earlier ones (such as Post's periodic focus electrostatic direct convertor) in that it makes use of the space charge repulsion in a high density charged particle beam. The beam is directed into a monotonic decelerating electrostatic field of a several-stage planar-finned structure. The collector fins coincide with vacuum equipotential surfaces. Space charge blowup of the beam directs particles onto various collector fins. The energy efficiency of a 4-stage device has been determined using a numberical simulation approach. We find that efficiencies approaching 75 percent are possible. An approximate scaling law is derived for the space charge based direct converter and a comparison is made to the periodic focus direct convertor. We find the space charge based direct convertor to be superior to a number of ways

  9. Direct effects of cattle on grassland birds in Canada.

    Bleho, Barbara I; Koper, Nicola; Machtans, Craig S


    Effects of grazing on grassland birds are generally thought to be indirect, through alteration of vegetation structure; however, livestock can also affect nest survival directly through trampling and other disturbances (e.g., livestock-induced abandonment). We extracted data on nest fates from 18 grazing studies conducted in Canada. We used these data to assess rates of nest destruction by cattle among 9 ecoregions and between seasonal and rotational grazing systems. Overall, few nests were destroyed by cattle (average 1.5% of 9132 nests). Nest destruction was positively correlated with grazing pressure (i.e., stocking rate or grazing intensity), but nest survival was higher in more heavily grazed areas for some species. Because rates of destruction of grassland bird nests by cattle are low in Canada, management efforts to reduce such destruction may not be of ecological or economic value in Canada. © 2014 Society for Conservation Biology.

  10. Fin field effect transistor directionality impacts printing of implantation shapes

    Wang, Xiren; Granik, Yuri


    In modern integrated circuit (IC) fabrication processes, the photoresist receives considerable illumination energy that is reflected by underlying topography during optical lithography of implantation layers. Bottom antireflective coating (BARC) is helpful to mitigate the reflection. Often, however, BARC is not used, because its removal is technically challenging, in addition to its relatively high economic cost. Furthermore, the advanced technology nodes, such as 14/10-nm nodes, have introduced fin field effect transistor (FinFET), which makes reflection from nonuniform silicon substrates exceptionally complicated. Therefore, modeling reflection from topography becomes obligatory to accurately predict printing of implantation shapes. Typically, FinFET is always fixed in one direction in realistic designs. However, the same implantation rectangle may be oriented in either horizontal or vertical direction. Then, there are two types of relations between the critical dimension (CD) and FinFET, namely a parallel-to and a perpendicular-to relation. We examine the fin directionality impact on CD. We found that this impact may be considerable in some cases. We use our in-house rigorous optical topography simulator to reveal underlining physical reasons. One of the major causes of the CD differences is that in the parallel orientation, the solid sidewalls of the fins conduct considerable light reflections unlike for the perpendicular orientation. This finding can aid the compact modeling in optical proximity correction of implantation masks.

  11. The Effect of Affect on Economic and Strategic Decision Making.

    The standard economic model of decision making assumes a decision maker makes her choices to maximize her utility or happiness. Her current emotional state is not explicitly considered. Yet there is a large psychological literature that shows that current emotional state, in particular positive affect, has a significant effect on decision making. This paper offers a way to incorporate this insight from psychology into economic modeling. Moreover, this paper shows that this simple insight can ...

  15. Assessment of the effect of innovation on the costs of a uranium ore concentration plant by means of a technical and economic model. Examples of applications: direct precipitation of the peroxide UO4 xH2O high temperature and high concentration alkaline treatment

    Boutonnet, G.; Roullier, J.P.


    Uranium Pechiney Ugine Kuhlmann has developed an economic model for uranium ore treatment plants. In this model, the basic economic data for a given plant, such as capital expenditures, operating costs, etc. are derived from parameters based partly on the size of the plant and the production progamme considered, and partly on the cost and specifications of the ore to be treated. In addition to numerous macro-economic applications (not considered here), the model can be used for making coherent comparisons of the economy of a plant designed for an innovative production process with that of the same plant designed for a conventional process of acid treatment followed by solvent extraction. The model shows that two new processes are highly competitive with the conventional process. They are: 1. Direct precipitation of the peroxide UO 4 xH 2 O in the pregnant liquor without concentration or purification by solvents or exchangers, and 2. High temperature and high concentration alkaline treatment

    Full Text Available Abstract Background Chronic fatigue syndrome (CFS is a debilitating chronic illness affecting at least 4 million people in the United States. Understanding its cost improves decisions regarding resource allocation that may be directed towards treatment and cure, and guides the evaluation of clinical and community interventions designed to reduce the burden of disease. Methods This research estimated direct and indirect costs of CFS and the impact on educational attainment using a population-based, case-control study between September 2004 and July 2005, Georgia, USA. Participants completed a clinical evaluation to confirm CFS, identify other illnesses, and report on socioeconomic factors. We estimated the effect of CFS on direct medical costs (inpatient hospitalizations, provider visits, prescription medication spending, other medical supplies and services and loss in productivity (employment and earnings with a stratified sample (n = 500 from metropolitan, urban, and rural Georgia. We adjusted medical costs and earnings for confounders (age, sex, race/ethnicity, education, and geographic strata using econometric models and weighted estimates to reflect response-rate adjusted sampling rates. Results Individuals with CFS had mean annual direct medical costs of $5,683. After adjusting for confounding factors, CFS accounted for $3,286 of these costs (p Conclusions Study results indicate that chronic fatigue syndrome may lead to substantial increases in healthcare costs and decreases in individual earnings. Studies have estimated up to 2.5% of non-elderly adults may suffer from CFS. In Georgia, a state with roughly 5.5 million people age 18-59, illness could account for $452 million in total healthcare expenditures and $1.2 billion of lost productivity.

  1. Direct economic burden and influencing factors in patients with hepatitis B virus related diseases in Jiangsu, China.

    Zhang, Hua; Chao, Jianqian; Zhu, Liguo; Song, Long; Li, Xiyan; Liu, Pei


    The purpose of this study was to explore direct economic burden and its influencing factors in patients with hepatitis B virus (HBV) related diseases. Time phasing continuous sampling was used to select patients from August 1, 2012, to December 31, 2012, in 3 county hospitals of 3 model regions in Jiangsu Province, China. A total of 436 outpatients and 196 inpatients were observed. The average direct economic burden of HBV-associated admission was US$107.11 for outpatients, and drug fees accounted for 74%; the burden was US$3193.47 for inpatients, and the direct medical costs accounted for 96%. Multivariate linear regression analysis showed that drug fee, examination fee, and antiviral therapy were influencing factors for outpatients, while hospitalization stay, drug ratio, and patient's age were influencing factors for inpatients. It can be concluded that the direct economic burden of patients with HBV-related diseases was high compared to their household income. Measures should be taken to reduce the economic burden of patients. © 2014 APJPH.

  2. Direct Demonstration of the Greenhouse Effect

    Jaffe, D. A.; Malashanka, S.; Call, K.; Bernays, N.


    Consider these three "theories:" climate change, evolution, and gravity. Why are two of them hotly debated by non-scientists, but not gravity? In part, the answer is that climate change and evolution are more complex processes and not readily observable over short time scales to most people. In contrast, the "theory of gravity" is tested every day by billions of people world-wide and is therefore not challenged. While there are numerous "demonstrations" of the greenhouse effect available online, unfortunately, many of them are based on poor understanding of the physical principles involved. For this reason, we sought to develop simple and direct experiments that would demonstrate aspects of the greenhouse effect that would be suitable for museums, K-12, and/or college classrooms. We will describe two experiments. In the first, we use a simple plexiglass tube, approximately 12 cm long, with IR transparent windows. The tube is first filled with dry nitrogen and exposed to an IR heat lamp. Following this, the tube is filled with pure, dry CO2. Both tubes warm up, but the tube filled with CO2 ends up about 0.7 degrees C warmer. It is useful to compare this 12 cm column of CO2 to the column in the earth's atmosphere, which is equivalent to approximately 2.7 meters of pure CO2. This demonstration would be suitable for museum exhibits to demonstrate the physical basis of CO2 heating in the atmosphere. In the second experiment, we use FTIR spectroscopy to quantify the CO2 content of ambient air and indoor/classroom air. For this experiment, we use a commercial standard of 350 ppm CO2 to calibrate the absorption features. Once the CO2 content of ambient air is found, it is useful for students to compare their observed value to background data (e.g. NOAA site in Hawaii) and/or the "Keeling Curve". This leads into a discussion on causes for local variations and the long-term trends. This experiment is currently used in our general chemistry class but could be used in many




    Full Text Available Financial information has, indisputably, an important effect in economics. To form an effective capital market, financial information must be reliable and accurate. Misleading financial information always has a negative impact on economic decision taken by users. It is known that financial information as the cornerstone of financial markets, can improve economic performance in several ways. Nowadays we are facing economic crisis due to irregularities of presentation of financial statements to users. Misunderstandings cause economic recession. Detection of fraudulent financial information, is an important issue facing the auditing profession. Currently, bankruptcy of companies around the world, leaves millions of people without jobs, this is caused by financial information which is manipulated by companies. The purpose of this paper is to analyze the effects of errors and manipulation committed in the financial information sector on the real economy. Also one of the purposes of this paper is to analyze error and fraud in financial statements how it effects the real economy and the reasons for committing fraud in financial statements. Also, several suggestions are included in this study about actions that can be taken to prevent errors and manipulation in financial information.

  4. Effects of labour migration on economic development during economic downturn and recovery

    Milan Palát


    Full Text Available International labour migration is mainly promoted by economic interests. This paper focuses on the period before and after the economic crisis and puts together important facts regarding motivation to labour migration and provides explanations of its causes and impacts on the macroeconomic level. The economic explanation why is migration so severely restricted is that migration policies are essentially distributive tools, aiming at reducing negative effects of migration on wages and unemployment among natives and moreover, we may stress out the gradualist tendencies of migration and such migration restrictions can mitigate supply-side shocks that may negatively affect incomes or jobs of some specific groups. A partial objective of the practical part of the paper is to evaluate relationships between the rate of migration and selected economic indicators using adequate quantitative methods. While the correlation between the crude rate of net migration and the GDP per capita is very low, the existence of correlation between the crude rate of net migration and the unemployment rate is evident in the most of analysed countries. Statistical insignificance of correlation indices in some countries can be then attributed to structural problems of those economies.

  5. Direct and Indirect Economic Burden of Chronic Liver Disease in the United States.

    Stepanova, Maria; De Avila, Leyla; Afendy, Mariam; Younossi, Issah; Pham, Huong; Cable, Rebecca; Younossi, Zobair M


    Chronic liver (CLD) is a major public health concern. We assessed its effects on quality of life and work productivity, as well as its economic burden in the United States. We performed a cross-sectional study of data from the Medical Expenditure Panel Survey (MEPS; 2004-2013). We extracted participants' sociodemographic parameters and medical histories. Subjects with CLD were identified based on Clinical Classification Software codes. MEPS participants were compared between those with and without CLD, and then between employed and unemployed patients with CLD. Outcomes were quality-of-life scores, employment, and health care use. We collected data from 230,406 adult participants (age, ≥18 y) in the MEPS; 1846 had current CLD (36.7% with viral hepatitis and 5.3% with liver cancer). Individuals with CLD were less likely to be employed (44.7% vs 69.6% patients without CLD), were not working owing to illness/disability (30.5% vs 6.6% without CLD), lost more work because of disability (10.2 vs 3.4 d without CLD), and had more health care use, producing greater health care expenses ($19,390 vs $5567/y without CLD) (all P < .0001). Patients with CLD also had more comorbidities and worse self-reported general and mental health status, and reported more health-related limitations in their daily activities than individuals without CLD (all P < .0001). They also indicated more psychologic distress and depressive symptoms and had a lower quality of life and health utility scores (P < .0001). In multivariate analysis, after adjustment for sociodemographic factors and comorbidities, the presence of CLD was an important predictor of unemployment (odds ratio, 0.60; 95% confidence interval, 0.50-0.70), annual health care expenditure (β = $9503 ± $2028), and impairment in all aspects of health-related quality of life (all P < .0001). In patients with CLD, the presence of liver cancer had the most profound impact on health care expenditures (β = $17,278 ± $5726/y) and

  6. Analysis of Economic Efficiency of Production of Low-Concentrated Sodium Hypochlorite by Direct Electrolysis of Natural Waters

    Fesenko, L. N.; Pchelnikov, I. V.; Fedotov, R. V.


    The study presents the economic efficiency of direct electrolysis of natural waters in comparison with the waters artificially prepared by electrolysis of the 3% sodium salt solution. The study used sea water (Black sea water); mineral water (underground water of the Melikhovskaya station, “Ognennaya” hole); brackish water (underground water from the Grushevskaya station of the Aksai district); 3% solution of sodium salt. As a result, the dependences characterizing the direct electrolysis of natural waters with different mineralization, economic, and energy parties are shown. The rational area of the electrolysis for each of the investigated solution is determined. The cost of a kilogram of active chlorine obtained by the direct water electrolysis: Black sea from 17.2 to 18.3 RUB/kg; the Melikhovskaya station “Ognennaya” hole - 14.3 to 15.0 Rubles/kg; 3% solution of NaCl - 30 Rubles./kg; Grushevskogo St. - 63,0-73,0 Rubles/kg.

  7. Combined use of leaf size and economics traits allows direct comparison of hydrophyte and terrestrial herbaceous adaptive strategies.

    Pierce, Simon; Brusa, Guido; Sartori, Matteo; Cerabolini, Bruno E L


    Hydrophytes generally exhibit highly acquisitive leaf economics. However, a range of growth forms is evident, from small, free-floating and rapidly growing Lemniden to large, broad-leaved Nymphaeiden, denoting variability in adaptive strategies. Traits used to classify adaptive strategies in terrestrial species, such as canopy height, are not applicable to hydrophytes. We hypothesize that hydrophyte leaf size traits and economics exhibit sufficient overlap with terrestrial species to allow a common classification of plant functional types, sensu Grime's CSR theory. Leaf morpho-functional traits were measured for 61 species from 47 water bodies in lowland continental, sub-alpine and alpine bioclimatic zones in southern Europe and compared against the full leaf economics spectrum and leaf size range of terrestrial herbs, and between hydrophyte growth forms. Hydrophytes differed in the ranges and mean values of traits compared with herbs, but principal components analysis (PCA) demonstrated that both groups shared axes of trait variability: PCA1 encompassed size variation (area and mass), and PCA2 ranged from relatively dense, carbon-rich leaves to nitrogen-rich leaves of high specific leaf area (SLA). Most growth forms exhibited trait syndromes directly equivalent to herbs classified as R adapted, although Nymphaeiden ranged between C and SR adaptation. Our findings support the hypothesis that hydrophyte adaptive strategy variation reflects fundamental trade-offs in economics and size that govern all plants, and that hydrophyte adaptive strategies can be directly compared with terrestrial species by combining leaf economics and size traits.

  8. Economic impact of latent heat thermal energy storage systems within direct steam generating solar thermal power plants with parabolic troughs

    Seitz, M.; Johnson, M.; Hübner, S.


    Highlights: • Integration of a latent heat thermal energy storage system into a solar direct steam generation power cycle. • Parametric study of solar field and storage size for determination of the optimal layout. • Evaluation of storage impact on the economic performance of the solar thermal power plant. • Economic comparison of new direct steam generation plant layout with state-of-the-art oil plant layout. - Abstract: One possible way to further reduce levelized costs of electricity of concentrated solar thermal energy is to directly use water/steam as the primary heat transfer fluid within a concentrated collector field. This so-called direct steam generation offers the opportunity of higher operating temperatures and better exergy efficiency. A technical challenge of the direct steam generation technology compared to oil-driven power cycles is a competitive storage technology for heat transfer fluids with a phase change. Latent heat thermal energy storages are suitable for storing heat at a constant temperature and can be used for direct steam generation power plants. The calculation of the economic impact of an economically optimized thermal energy storage system, based on a latent heat thermal energy storage system with phase change material, is the main focus of the presented work. To reach that goal, a thermal energy storage system for a direct steam generation power plant with parabolic troughs in the solar field was thermally designed to determine the boundary conditions. This paper discusses the economic impact of the designed thermal energy storage system based on the levelized costs of electricity results, provided via a wide parametric study. A state-of-the-art power cycle with a primary and a secondary heat transfer fluid and a two-tank thermal energy storage is used as a benchmark technology for electricity generation with solar thermal energy. The benchmark and direct steam generation systems are compared to each other, based respectively

    Subramanian, S V; Subramanyam, Malavika A


    About two of every five undernourished young children of the world live in India. These high levels of child undernutrition have persisted in India for several years, even in its relatively well-developed states. Moreover, this pattern was observed during a period of rapid economic growth. Evidence from India and other developing countries suggests that economic growth has little to no impact on reducing child undernutrition. We argue that a growth-mediated strategy is unlikely to be effectiv...

  10. Awareness of the implementation of the Falsified Medicines Directive among pharmaceutical companies’ professionals in the European Economic Area

    Włodarczak U


    Full Text Available Background: The Falsified Medicines Directive (FMD is a response of the European Union to the increasing number of falsified medicines present in the legal supply chain within the Member States of the community. Effective implementation of the new regulations will depend on the effective cooperation of all parties involved in the distribution of medicinal products including the managers of pharmaceutical companies. Objective: The objective of the study was to examine awareness of the Implementation of the FMD among pharmaceutical company professionals in the European Economic Area. Methods: Sampling was conducted using a method called purposive sampling. An appropriate research tool in the form of an original questionnaire was made available to the respondents in electronic form. During the period from January 2016 to June 2016, 1,496 e-mail messages were sent. The response rate was 17.37%. Results: The study included 99 women (39.3% and 153 men (60.7%. In the study group, 95.7% of people had heard of FMD. Doctors had rarely heard about the falsified medicine directive when compared to pharmacists (p=0.0063, people working in the pharmaceutical industry (p=0.0014, and respondents with a different professional profile (p=0.0114. In the study group, 89.6% of people were aware of the role of National Medicines Verification Organization in the process of implementing the provisions of FMD into the national system of distribution of medicinal products. The number of the respondents who knew the deadline for the implementation of FMD was significantly higher in the study population, i.e. 91.9% (p=0.0001. Both the younger respondents and those with lower level of education were less aware of the time requirements posed to national regulators (p=0.0003, p=0.0023, respectively. Conclusions: Awareness of the regulations related to the implementation of the FMD, although relatively high among pharmaceutical company professionals in the EEA, is still

  11. The intrusion of the discourse of economics into the clinical space III: economic rationalism and clinical effects.

    Plastow, Michael


    Language has always been a means of imposing political and economic dominance. The ascendancy of the discourse of economics is examined in the context of economic rationalism. Some of the effects of this discourse, both upon our services, as well as upon different modes of conceptualizing the therapeutic relationship, will be examined in this paper. The intensification of the use of terms from economics and management can be dated from the introduction of neo-liberal policies in our Western democracies, but the economic discourse circulates with a life of its own. The use of the language of economics and management has spread generally through our society. Thus, if the economic discourse is the language utilized by some clinicians, it is also to some degree the language adopted by our patients. It is proposed that the extension of the economic discourse into the clinical field is re-shaping the therapeutic relationship with our patients.

  14. A health economic model for the development and evaluation of innovations in aged care: an application to consumer-directed care-study protocol.

    Ratcliffe, Julie; Lancsar, Emily; Luszcz, Mary; Crotty, Maria; Gray, Len; Paterson, Jan; Cameron, Ian D


    Consumer-directed care is currently being embraced within Australia and internationally as a means of promoting autonomy and choice in the delivery of health and aged care services. Despite its wide proliferation little research has been conducted to date to assess the views and preferences of older people for consumer-directed care or to assess the costs and benefits of such an approach relative to existing models of service delivery. A comprehensive health economic model will be developed and applied to the evolution, implementation and evaluation of consumer-directed care in an Australian community aged care setting. A mixed methods approach comprising qualitative interviews and a discrete choice experiment will determine the attitudes and preferences of older people and their informal carers for consumer-directed care. The results of the qualitative interviews and the discrete choice experiment will inform the introduction of a new consumer-directed care innovation in service delivery. The cost-effectiveness of consumer-directed care will be evaluated by comparing incremental changes in resource use, costs and health and quality of life outcomes relative to traditional services. The discrete choice experiment will be repeated at the end of the implementation period to determine the extent to which attitudes and preferences change as a consequence of experience of consumer-directed care. The proposed framework will have wide applicability in the future development and economic evaluation of new innovations across the health and aged care sectors. The study is approved by Flinders University Social and Behavioural Research Ethics Committee (Project No. 6114/SBREC). Findings from the qualitative interviews, discrete choice experiments and the economic evaluation will be reported at a workshop of stakeholders to be held in 2015 and will be documented in reports and in peer reviewed journal articles.

    Full Text Available Summary. At the present stage of development of domestic agricultural production is a key strategic direction of the innovative development of the industry. Tasked by the government to effectively modernize the economy reflect the latest scientific and technological progress, innovation, positive perception of new ideas and breakthrough technologies. In this regard, the decisive role played by the information network , computer systems, high production technology and intellectual resources of society, innovative organization of various spheres of human activity , as well as a new level of relations to knowledge. The main driving force of innovation development of agro-industrial production in Russia at the present stage is the human potential to carry out the restructuring of the agricultural sector with the latest achievements of scientific and technical progress. Famous slogan - "cadres decide everything" under the innovation paradigm of reforming the economy is of particular relevance. One of the important reasons for the low level of innovative development of agricultural production is the lack of motivation of creative work in the agricultural workers business organizations. For the development of advanced technologies for improving the quality and reducing the material cost per unit of cash - produ Dima products they do not receive adequate material compensation. This is largely inhibits the activity of employees in the development of advanced low-cost and resource-saving technologies in agricultural production. We propose an original model for innovative employee incentiveing activity and a real contribution to improving the efficiency of the enterprise. To take into account the personal contribution of the employee in additional economic benefit through innovative component and determining bonuses, proposed to use the "coefficient of innovation activity employee" (CIAE. The value of this coefficient is defined as the ratio of profits

    This paper reviews the empirical literature concerning the direct rebound effect in households; it briefly analyzes the main theoretical and methodological aspects, and finally estimates the magnitude of direct rebound effect for all energy services using electricity in households of Catalonia (Spain) using econometric techniques. The main results show an estimated direct rebound effect of 35% in the short term and 49% in the long term. The existence of a rebound effect reduces the effectiveness of energy efficiency policies.

  9. Estimates of the Economic Effects of Sea Level Rise

    Darwin, R.F.; Tol, R.S.J.


    Regional estimates of direct cost (DC) are commonly used to measure the economic damages of sea level rise. Such estimates suffer from three limitations: (1) values of threatened endowments are not well known, (2) loss of endowments does not affect consumer prices, and (3) international trade is disregarded. Results in this paper indicate that these limitations can significantly affect economic assessments of sea level rise. Current uncertainty regarding endowment values (as reflected in two alternative data sets), for example, leads to a 17 percent difference in coastal protection, a 36 percent difference in the amount of land protected, and a 36 percent difference in DC globally. Also, global losses in equivalent variation (EV), a welfare measure that accounts for price changes, are 13 percent higher than DC estimates. Regional EV losses may be up to 10 percent lower than regional DC, however, because international trade tends to redistribute losses from regions with relatively high damages to regions with relatively low damages. 43 refs

  10. The influence of economic crisis on directions of estructuring of marketing in research institutes

    Marlena Elżbieta Maślanka


    Full Text Available On the eve of the third millennium the Polish economy is more and more subject to worldwide trends of globalization, which in a special way influences the scope and intensiveness of changes implemented in Research Institutes. It is accompanied by another more and more intensively transferred internationally and generally observed economic crisis, whose negative impulses cause the economic growth to slow down. The key determinant of the development of Research Institutes in the modern global economy is a skill to react on changes and a necessity to take restructuring actions within this range of marketing. Problems of a progressive global economic crisis and the influence of this process on restructuring of marketing in Research Institutes is an important research problem, requiring a deep and thorough analysis and research in this scope, hence this paper deals with all these important issues.

  11. The Impact of Foreign Direct Investments and Remittances on Economic Growth: A Case Study in Central and Eastern Europe

  15. The Annual Economic Burden of Syphilis: An Estimation of Direct, Productivity, and Intangible Costs for Syphilis in Guangdong Initiative for Comprehensive Control of Syphilis Sites.

    Zou, Yaming; Liao, Yu; Liu, Fengying; Chen, Lei; Shen, Hongcheng; Huang, Shujie; Zheng, Heping; Yang, Bin; Hao, Yuantao


    Syphilis has continuously posed a great challenge to China. However, very little data existed regarding the cost of syphilis. Taking Guangdong Initiative for Comprehensive Control of Syphilis area as the research site, we aimed to comprehensively measure the annual economic burden of syphilis from a societal perspective. Newly diagnosed and follow-up outpatient cases were investigated by questionnaire. Reported tertiary syphilis cases and medical institutions cost were both collected. The direct economic burden was measured by the bottom-up approach, the productivity cost by the human capital method, and the intangible burden by the contingency valuation method. Three hundred five valid early syphilis cases and 13 valid tertiary syphilis cases were collected in the investigation to estimate the personal average cost. The total economic burden of syphilis was US $729,096.85 in Guangdong Initiative for Comprehensive Control of Syphilis sites in the year of 2014, with medical institutions cost accounting for 73.23% of the total. Household average direct cost of early syphilis was US $23.74. Average hospitalization cost of tertiary syphilis was US $2,749.93. Of the cost to medical institutions, screening and testing comprised the largest proportion (26%), followed by intervention and case management (22%) and operational cost (21%). Household average productivity cost of early syphilis was US $61.19. Household intangible cost of syphilis was US $15,810.54. Syphilis caused a substantial economic burden on patients, their families, and society in Guangdong. Household productivity and intangible costs both shared positive relationships with local economic levels. Strengthening the prevention and effective treatment of early syphilis could greatly help to lower the economic burden of syphilis.

  18. Direct-to-consumer promotion of prescription drugs. Economic implications for patients, payers and providers.

    Findlay, S D


    Spending on outpatient prescription drugs in the US is accelerating rapidly. Although numerous factors are driving this trend, attention has recently focused on the role played by the marketing, promotion and advertising of pharmaceuticals, in particular direct-to-consumer (DTC) advertising. In 1997, the US Food and Drug Administration (FDA) issued a 'guidance' on such mass media promotion. The guidance altered existing FDA rules and effectively permitted pharmaceutical companies to promote prescription drugs on television and radio without giving detailed or even summary information on indications, efficacy or potential adverse effects. Since then, television commercials, in particular, and print advertisements in consumer magazines and newspapers have proliferated rapidly. Pharmaceutical companies spent $US1.8 billion on DTC advertising in 1999, a 40% increase over 1998. This spending in 1999 was heavily concentrated on about 50 drugs. Evidence is growing that DTC promotion of prescription drugs is: (i) alerting consumers to the existence of new drugs and the conditions they treat; (ii) increasing consumer demand for many drugs; (iii) contributing increasingly to the recent sharp increase in the number of prescriptions being dispensed; (iv) raising sales revenues; and, thus, (v) contributing to the higher pharmaceutical costs of health insurers, government and consumers. The public policy issues surrounding DTC advertisements centre on the following questions: (i) are the advertisements leading to the inappropriate clinical use of some drugs? (ii) are the advertisements inducing both consumers and physicians to choose more costly new brand-name drugs over less expensive, but equally effective, older brand or generic drugs? (iii) do television advertisements for prescription drugs contain a balanced amount of information on benefits versus potential adverse effects? and (iv) will the revenue benefits generated by DTC advertising cause pharmaceutical companies to

  19. Economic Effects of Precipitation Enhancement in the Corn Belt.

    Gapcia, Philip; Changnon, Stanley; Pinar, Musa


    Policy formulation in weather modification requires an understanding of the economic effects from altered weather. The focus of this study is to provide insight into the beneficiaries of a functioning weather modification technology when applied at various spatial and temporal levels. An econometric model which links the corn/scybean production to U.S. cattle, hog and poultry sectors is used to determine the effects of precipitation enhancement in the U.S. Corn Belt, a humid climatic region. A regional supply formulation permits assessment of weather modification on production, prices, revenues to producers, and savings in consumers expenditures on meat. The results provide insight into the distribution of economic effects, emphasize the importance of careful planning in the use of weather modification technology, and provide useful information on the roles of local, state, and federal governments in the support of weather modification.

  20. The debate on the economic effects of minimum wage legislation

    Santos Miguel Ruesga-Benito


    Full Text Available The minimum wage establishment has its origin in the first third of the last century. Since its creation has been a focus of continuing controversy and an unfinished debate on economics field. This work reviews the effects of the minimum wage on employment and other macroeconomic variables, from both theoretical and empirical perspectives. The method is based on the revision of the literature and the main economic indicators. The central contribution of this paper is providing a general reflection on theoretical and empirical analysis about the debate on minimum wage and its effects. The results showed that some labor policies are taking account the effects of austerity strategies, shifting the attention towards the implementation of minimum wages or their updating, in order to reduce the growing inequalities in the distribution of income, and even poverty levels.

    Full Text Available The objective of the study is to investigate the most promising economic variables i.e., foreign direct investment (FDI, exports and financial development on economic growth in selected South Asian Association of Regional Co-corporation (SAARC countries. In addition, this study argued that whether FDI, Exports and financial development fosters or hinder economic growth in SAARC countries, for this purpose, panel data set of selected five SAARC countries namely, Bangladesh, India, Nepal, Pakistan and Srilanka considered for empirical consideration over a period of 1975 to 2011. By using two-stage least square (2SLSL technique, empirical evidence on the effects of FDI, exports and financial development on economic growth is mix in terms of apriori expectations. In case of Bangladesh, exports and broad money supply (M2 is the positive and significant contributor to increase economic growth, whereas, M2 increases India’s GDP. FDI is the only significant contributor to increase Pakistan’s economic growth. In case of Nepal and Srilanka, broad money supply increases economic growth, whereas, due to high dependency on imports, exports could not considerably increases economic growth in those regions.

    This paper reviews economic principles for optimality of the taxation of international profit, from both a global and national perspective. It argues that for traditional systems based on the residence of the investor or the source of the income, nothing less than full harmonization across countries can achieve global optimality. The conditions for national optimality are more difficult to identify, but are most likely to imply source-based taxation. However, source-based taxation requires an...

  4. Economic Effects of Migration from Poland to the UK

    Mihaela Simionescu


    Full Text Available Considering that large numbers of the EU-8 immigrants was a strong argument for the Brexit, the objective of this paper is to assess some economic effects of migration from Poland to the UK for both countries. Intensive emigration of the Poles to the UK since 2004 negatively affected Poland’s economic growth in the long run, but it also reduced tensions at the labour market by decreasing the unemployment rate. On the other hand, the increase in Polish immigrants in the UK did not significantly affect economic growth and unemployment rate in the destination country in the short run in the period 2004-2015. A significance influence was observed only in the long run, when the UK economic growth decreased, but the pressures on the labour market significantly reduced. From these empirical findings, some policy recommendations are required for both countries: for Poland, migration policies to promote the return of migrants and more efficient utilization of labour force, while for the UK – shaping a more flexible labour market.

  5. The Effects of Economic Sanctions on the Informal Economy

    Ioana M. PETRESCU


    Full Text Available Countries often use economic sanctions to coerce other countries to change certain policies of which they do not approve. However, if sanctioned countries smuggle goods over the border, use informal financial intermediaries, and develop black markets to trade sanctioned goods, sanctions end up having a smaller impact, sanctioned countries have little incentive to modify their policies, and sanctions are more likely to fail. This paper is the first study to test empirically whether sanctions affect informality. I compile data from different studies about the size of the informal market for 147 countries over 46 years. I use these data to analyze the relationship between the size of the informal market adjusted by the size of the population and economic sanctions. I also estimate at the impact of economic sanctions on other activities associated with informal activities. I find that informal markets increase when a country is being sanctioned and the effects are larger when the economic sanction has strong international support. I also find that the type of sanction, trade or financial, is not an important determinant of the informal market size and that sanctions also lead to increases in robbery rates and corruption.

  9. Economic feasibility study of biodiesel production by direct esterification of fatty acids from the oil and soap industrial sector

    M.I. El-Galad


    Full Text Available Industrial production of biodiesel fuel in Egypt by the transesterification of vegetable oils is being faced with the problem of feedstock shortage. Egypt imports annually about 90% of its needs as edible oils for human consumption. The production of biodiesel by direct esterification of fatty acids that can be obtained from the oil and soap industrial sector in huge quantities each year (around 16 thousand tons may be a proper solution to this problem. According to results of a previous study [1], the biodiesel produced following this approach and using methyl alcohol was quite efficient as an alternative fuel for diesel engines. However, the process should be economically feasible for application on an industrial scale. The present study assessed the economic feasibility of biodiesel production by direct fatty acid esterification. Complete process simulation was first carried out using the process simulation software, Aspen HYSYS V7.0. The process was then designed comprising four main steps being esterification, solvent recovery, catalyst removal and water removal. The main processing units include the reactor, distillation column, heat exchangers, pumps and separators. Assuming that the rate of fatty acids esterified was 2 ton/h, all process units required have been sized. Total capital investment, total manufacturing cost and return on investment were all estimated. The latter was found to be 117.1% which means that the production process is quite economically feasible.

  11. Direct and indirect economics of wind energy systems relative to fuel based systems

    Sorensen, B


    It is shown that the addition of an energy-storage system of modest capacity, to a wind energy generator, provides a total-wind-energy electricity-generating system as dependable as current alternative means of producing electricity. It is further shown, based on projections of the mass-production costs of wind-energy generators and energy-storage systems, that such combined systems, as well as fuel-saving generators without storage, appear economically competitive to the alternatives, provided the comparison is made over the entire life cycle of the systems.

  12. A reconsideration of effect of energy scarcity on economic growth

    Uri, N.D.


    This analysis is concerned with the effect of energy scarcity on economic growth in the U.S. After defining the notion of scarcity and introducing measures of scarcity (unit costs and relative energy price), changes in the trend in resource scarcity for NG, bituminous coal, anthracite coal, and crude oil over the most recent three decades are investigated. Each of the energy resources became a significantly scarcer resource during the decade of the 1970s in the Malthusian Stock Scarcity and Malthusian Flow Scarcity sense. Unit costs exhibit a similar change for NG and crude oil but not for bituminous and anthracite coals. The situation reversed itself during the 1980s. NG, bituminous and anthracite coals, and crude oil all became significantly less scarce resources during the decade of the 1980s than they had been during the 1970s, i.e. the increase in scarcity as measured by relative energy prices observed during the decade of the 1970s was not reversed completely during the 1980s for NG and crude oil demonstrate similar patterns. Given that change has taken place, it has implications for future economic growth to the extent resource scarcity and economic growth are interrelated. To see whether this is a relevant concern, subsequent to the examination of changing resource scarcity trends, an objective effort is made to identify a long run equilibrium relationship between energy scarcity and economic growth. Relying on cointegration techniques, only for crude oil is there a suggestion that resource scarcity has affected economic growth in the U.S. over the period 1889-1992. (author)

  17. Direct counterfactual communication via quantum Zeno effect

    Cao, Yuan; Li, Yu-Huai; Cao, Zhu; Yin, Juan; Chen, Yu-Ao; Yin, Hua-Lei; Chen, Teng-Yun; Ma, Xiongfeng; Peng, Cheng-Zhi; Pan, Jian-Wei


    Intuition from our everyday lives gives rise to the belief that information exchanged between remote parties is carried by physical particles. Surprisingly, in a recent theoretical study [Salih H, Li ZH, Al-Amri M, Zubairy MS (2013) Phys Rev Lett 110:170502], quantum mechanics was found to allow for communication, even without the actual transmission of physical particles. From the viewpoint of communication, this mystery stems from a (nonintuitive) fundamental concept in quantum mechanics—wave-particle duality. All particles can be described fully by wave functions. To determine whether light appears in a channel, one refers to the amplitude of its wave function. However, in counterfactual communication, information is carried by the phase part of the wave function. Using a single-photon source, we experimentally demonstrate the counterfactual communication and successfully transfer a monochrome bitmap from one location to another by using a nested version of the quantum Zeno effect.

  18. The neural correlates of endowment effect without economic transaction.

    Votinov, Mikhail; Mima, Tatsuya; Aso, Toshihiko; Abe, Mitsunari; Sawamoto, Nobukatsu; Shinozaki, Jun; Fukuyama, Hidenao


    People always concern about what they have and what they might lose even it is just imaginary property. According to Prospect Theory, the losses might be weighted by subjects higher than gain, which would cause the disparity between the willingness to accept (WTA) and willingness to pay (WTP) compensation in economic valuation. Using functional MRI, we investigated neural correlates of this inconsistent value estimation, known as the endowment effect, during a simple pricing task without economic transaction. Brain activation associated with this price discrepancy was observed in the right inferior frontal gyrus (IFG), where voxel-based morphometry of MRI revealed the positive correlation between gray matter concentration and WTA/WTP ratio. These findings suggest the functional relevance of IFG in WTA/WTP discrepancy for pricing without any actual gain and loss, where an integration of loss aversion-related signals from insula and expected value signals may occur. 2010 Elsevier Ireland Ltd and the Japan Neuroscience Society.

  19. Cost-effective design of economic instruments in nutrition policy

    Smed Sinne


    Full Text Available Abstract This paper addresses the potential for using economic regulation, e.g. taxes or subsidies, as instruments to combat the increasing problems of inappropriate diets, leading to health problems such as obesity, diabetes 2, cardiovascular diseases etc. in most countries. Such policy measures may be considered as alternatives or supplements to other regulation instruments, including information campaigns, bans or enhancement of technological solutions to the problems of obesity or related diseases. 7 different food tax and subsidy instruments or combinations of instruments are analysed quantitatively. The analyses demonstrate that the average cost-effectiveness with regard to changing the intake of selected nutritional variables can be improved by 10–30 per cent if taxes/subsidies are targeted against these nutrients, compared with targeting selected food categories. Finally, the paper raises a range of issues, which need to be investigated further, before firm conclusions about the suitability of economic instruments in nutrition policy can be drawn.

  1. Economic development and foreign direct investment: How to create sustainable development an analysis of the potential for sustainable development on the Indian subcontinent

    Homlong Nathalie


    Full Text Available Focusing critically on the effects of the conditions for foreign direct investment on sustainable growth in the recipient country, this paper analyzes the potential for investments in environmental innovations in India. The definition of sustainability applied in this paper incorporates economic development and investment which promotes environmentally and socially friendly production and innovation. As the Indian economy experienced strong growth in GDP in recent years, but is still lagging behind in providing the basic needs of clean water, clean air and proper waste management for households and companies, the necessity for sustainable development exists. From a methodological point of view this paper uses macroeconomic data to evaluate quantitatively the potentials and needs of Indian states. This results in a state ranking showing the potential for sustainable development in selected Indian states, based on economic and environmental indicators.

  4. [Assessing the economic impact of cancer in Chile: a direct and indirect cost measurement based on 2009 registries].

    Cid, Camilo; Herrera, Cristian; Rodríguez, Rodrigo; Bastías, Gabriel; Jiménez, Jorge


    This paper aims to determine the economic impact that cancer represents to Chile, exploring the share of costs for the most important cancers and the differences between the public and private sector. We used the cost of illness methodology, through the assessment of the direct and indirect costs associated with cancer treatment. Data was obtained from 2009 registries of the Chilean Ministry of Health and the Superintendence of Health. Indirect costs were calculated by days of job absenteeism and potential years of life lost. Over US$ 2.1 billion were spent on cancer in 2009, which represents almost 1% of Chile’s Gross Domestic Product. The direct per capita cost was US$ 47. Indirect costs were 1.92 times more than direct costs. The three types of cancer that embody the highest share of costs were gastric cancer (17.6%), breast cancer (7%) and prostate cancer (4.2%) in the public sector, and breast cancer (14%), lung cancer (7.5%) and prostate cancer (4.1%) in the private sector. On average men spent 30.33% more than women. There are few studies of this kind in Chile and the region. The country can be classified as having a cancer economic impact below the average of those in European Union countries. We expect that this information can be used to develop access policies and resource allocation decision making, and as a first step into further cancer-costing studies in Chile and the Latin American and Caribbean region.

  6. Direct effect of acid rain on leaf chlorophyll content of terrestrial plants in China.

    Du, Enzai; Dong, Dan; Zeng, Xuetong; Sun, Zhengzhong; Jiang, Xiaofei; de Vries, Wim


    Anthropogenic emissions of acid precursors in China have resulted in widespread acid rain since the 1980s. Although efforts have been made to assess the indirect, soil mediated ecological effects of acid rain, a systematic assessment of the direct foliage injury by acid rain across terrestrial plants is lacking. Leaf chlorophyll content is an important indicator of direct foliage damage and strongly related to plant productivity. We synthesized data from published literature on experiments of simulated acid rain, by directly exposing plants to acid solutions with varying pH levels, to assess the direct effect of acid rain on leaf chlorophyll content across 67 terrestrial plants in China. Our results indicate that acid rain substantially reduces leaf chlorophyll content by 6.71% per pH unit across the recorded plant species. The direct reduction of leaf chlorophyll content due to acid rain exposure showed no significant difference across calcicole, ubiquist or calcifuge species, implying that soil acidity preference does not influence the sensitivity to leaf injury by acid rain. On average, the direct effects of acid rain on leaf chlorophyll on trees, shrubs and herbs were comparable. The effects, however varied across functional groups and economic use types. Specifically, leaf chlorophyll content of deciduous species was more sensitive to acid rain in comparison to evergreen species. Moreover, vegetables and fruit trees were more sensitive to acid rain than other economically used plants. Our findings imply a potential production reduction and economic loss due to the direct foliage damage by acid rain. Copyright © 2017 Elsevier B.V. All rights reserved.

  7. Direction of Causality Between Financial Development and Economic Growth. Evidence for Developing Countries

    Borlea Sorin Nicolae


    Full Text Available The results of extensive studies that analyzed the existence and meaning of correlations between the economic growth and the financial market development lead us to a more thorough study of these correlations. Therefore, we performed a broad study of the developing countries from around the world (the developing part of each region constructed by the World Bank through its Statistics Bureau. The regions taken into analysis were: Europe and Central Asia, South Asia, East Asia and the Pacific, the Arab world, Latin America & and the Caribbean, the Middle East and North Africa, and Sub-Saharan Africa. For comparison purposes, we have also included in the sample the North American countries, the Euro Area and the European Union as a whole, because these last three areas are the main benchmarks of the financial markets. The results are consistent with those from previous studies on the subject and vary depending on region and financial indicator considered.

  8. Peripartum hysterectomy: an economic analysis of direct healthcare costs using routinely collected data.

    Achana, F A; Fleming, K M; Tata, L J; Sultan, A A; Petrou, S


    To estimate resource use and costs associated with peripartum hysterectomy for the English National Health Service. Analysis of linked Clinical Practice Research Datalink and Hospital Episodes Statistics (CPRD-HES) data. Women undergoing peripartum hysterectomy between 1997 and 2013 and matched controls. Inverse probability weighted generalised estimating equations were used to model the non-linear trend in healthcare service use and costs over time, accounting for missing data, adjusting for maternal age, body mass index, delivery year, smoking and socio-economic indicators. Primary care, hospital outpatient and inpatient attendances and costs (UK 2015 prices). The study sample included 1362 women (192 cases and 1170 controls) who gave birth between 1997 and 2013; 1088 (153 cases and 935 controls) of these were deliveries between 2003 and 2013 when all categories of hospital resource use were available. Based on the 2003-2013 delivery cohort, peripartum hysterectomy was associated with a mean adjusted additional total cost of £5380 (95% CI £4436-6687) and a cost ratio of 1.76 (95% CI 1.61-1.98) over 5 years of follow up compared with controls. Inpatient costs, mostly incurred during the first year following surgery, accounted for 78% excluding or 92% including delivery-related costs. Peripartum hysterectomy is associated with increased healthcare costs driven largely by increased post-surgery hospitalisation rates. To reduce healthcare costs and improve outcomes for women who undergo hysterectomy, interventions that reduce avoidable repeat hospitalisations following surgery such as providing active follow up, treatment and support in the community should be considered. A large amount of NHS data on peripartum hysterectomy suggests active community follow up could reduce costs, #HealthEconomics. © 2017 Royal College of Obstetricians and Gynaecologists.

  9. The economic implications of a multimodal analgesic regimen for patients undergoing major orthopedic surgery: a comparative study of direct costs.

    Duncan, Christopher M; Hall Long, Kirsten; Warner, David O; Hebl, James R


    Total knee and total hip arthoplasty (THA) are 2 of the most common surgical procedures performed in the United States and represent the greatest single Medicare procedural expenditure. This study was designed to evaluate the economic impact of implementing a multimodal analgesic regimen (Total Joint Regional Anesthesia [TJRA] Clinical Pathway) on the estimated direct medical costs of patients undergoing lower extremity joint replacement surgery. An economic cost comparison was performed on Mayo Clinic patients (n = 100) undergoing traditional total knee or total hip arthroplasty using the TJRA Clinical Pathway. Study patients were matched 1:1 with historical controls undergoing similar procedures using traditional anesthetic (non-TJRA) techniques. Matching criteria included age, sex, surgeon, type of procedure, and American Society of Anesthesiologists (ASA) physical status (PS) classification. Hospital-based direct costs were collected for each patient and analyzed in standardized inflation-adjusted constant dollars using cost-to-charge ratios, wage indexes, and physician services valued using Medicare reimbursement rates. The estimated mean direct hospital costs were compared between groups, and a subgroup analysis was performed based on ASA PS classification. The estimated mean direct hospital costs were significantly reduced among TJRA patients when compared with controls (cost difference, 1999 dollars; 95% confidence interval, 584-3231 dollars; P = 0.0004). A significant reduction in hospital-based (Medicare Part A) costs accounted for the majority of the total cost savings. Use of a comprehensive, multimodal analgesic regimen (TJRA Clinical Pathway) in patients undergoing lower extremity joint replacement surgery provides a significant reduction in the estimated total direct medical costs. The reduction in mean cost is primarily associated with lower hospital-based (Medicare Part A) costs, with the greatest overall cost difference appearing among patients

  10. Direct coupled amplifiers using field effect transistors

    Fowler, E P [Control and Instrumentation Division, Atomic Energy Establishment, Winfrith, Dorchester, Dorset (United Kingdom)


    The concept of the uni-polar field effect transistor (P.E.T.) was known before the invention of the bi-polar transistor but it is only recently that they have been made commercially. Being produced as yet only in small quantities, their price imposes a restriction on use to circuits where their peculiar properties can be exploited to the full. One such application is described here where the combination of low voltage drift and relatively low input leakage current are necessarily used together. One of the instruments used to control nuclear reactors has a logarithmic response to the mean output current from a polarised ionisation chamber. The logarithmic signal is then differentiated electrically, the result being displayed on a meter calibrated to show the reactor divergence or doubling time. If displayed in doubling time the scale is calibrated reciprocally. Because of the wide range obtained in the logarithmic section and the limited supply voltage, an output of 1 volt per decade change in ionisation current is used. Differentiating this gives a current of 1.5 x 10{sup -8} A for p.s.D. (20 sec. doubling time) in the differentiating amplifier. To overcome some of the problems of noise due to statistical variations in input current, the circuit design necessitates a resistive path to ground at the amplifier input of 20 M.ohms. A schematic diagram is shown. 1. It is evident that a zero drift of 1% can be caused by a leakage current of 1.5 x 10{sup -10} A or an offset voltage of 3 mV at the amplifier input. Although the presently used electrometer valve is satisfactory from the point of view of grid current, there have been sudden changes in grid to grid voltage (the valve is a double triode) of up to 10 m.V. It has been found that a pair of F.E.T's. can be used to replace the electrometer valve so long as care is taken in correct balance of the two devices. An investigation has been made into the characteristics of some fourteen devices to see whether those with

  11. Economic potentials of CHP connected to district heat systems in Germany. Implementation of the EU Efficiency Directive

    Eikmeier, Bernd


    The EU Efficiency Directive (2012/27/EU) is requiring all member states to carry out an evaluation of the potential for highly efficient CHP and the efficient use of district heating and cooling by December 2015. The German Federal Ministry of Economic Affairs and Energy appointed this task to the Fraunhofer Institute for Manufacturing and Advanced Materials, division for Energy Systems Analysis (formerly Bremer Energie Institut) in conjunction with other partners. The results for the sector district- and communal heating with CHP, sub-sectors private households, trade and services industry, are presented in this article.

  13. Effects of flow gradients on directional radiation of human voice.

    Pulkki, Ville; Lähivaara, Timo; Huhtakallio, Ilkka


    In voice communication in windy outdoor conditions, complex velocity gradients appear in the flow field around the source, the receiver, and also in the atmosphere. It is commonly known that voice emanates stronger towards the downstream direction when compared with the upstream direction. In literature, the atmospheric effects are used to explain the stronger emanation in the downstream direction. This work shows that the wind also has an effect to the directivity of voice also favouring the downstream direction. The effect is addressed by measurements and simulations. Laboratory measurements are conducted by using a large pendulum with a loudspeaker mimicking the human head, whereas practical measurements utilizing the human voice are realized by placing a subject through the roof window of a moving car. The measurements and a simulation indicate congruent results in the speech frequency range: When the source faces the downstream direction, stronger radiation coinciding with the wind direction is observed, and when it faces the upstream direction, radiation is not affected notably. The simulated flow gradients show a wake region in the downstream direction, and the simulated acoustic field in the flow show that the region causes a wave-guide effect focusing the sound in the direction.




    Full Text Available Foreign direct investments are an important component of financial resources needed for the development of any economy. Attract them should represent a desideratum in economic development strategies, fact which requires providing a favorable climate, generated by a set of economic, political, social or legal conditions. The effects generated by FDI at the macroeconomic level, are reported in plan of economic growth, at the level of balance of payments and the state budget, and also on the labor market. In the paper are presented aspects of the process of attracting FDI in Romania after the transition to market economy and is realized a meaningful analysis of flows and corresponding balances between 2003-2012. The research has enabled the formulation of important conclusions regarding the evolution of FDI, their effects and the favorable conditions for their assimilation in the romanian economy.

  15. Equity effects of economic instruments for greenhouse gas abatement

    Harrison, D. Jr.


    This paper discusses the equity effects of using economic instruments--such as a carbon tax or carbon emissions trading program--to regulate greenhouse gas emissions. Determining these equity effects is more complicated than assessing overall costs and benefits, although some of the same issues arise. Among the key issues are the following: (1) benchmark for evaluating impacts of economic instruments (status quo or regulatory program that achieves the same emission reductions); (2) use of any government revenues collected, which are transfers overall but affect gains and losses; (3) time period (long-term or transitional impacts); and (4) groupings (income groups, sectors or regions). Empirical studies suggest that a national tax is regressive in the US but may be less so in other countries. The equity impacts of an international carbon tax or emissions trading program differ greatly depending upon the specific elements. The paper considers options to compensate or mitigate adverse effects to income groups, sectors, or regions of the world. Although impossible to avoid all losses to every group, it would be possible to avoid major equity effects if carbon taxes or carbon trading programs were used to control global warming

  16. Atmospheric natural disasters in Serbia: Management experience and economic effects

    Nikolić Jugoslav


    Full Text Available Natural disasters occur as a result of an action of natural forces and represent limitations in spatial planning and efficient spatial development, with different consequences in terms of scope on humans, living things and tangible property. Consequences can be ecological, economic, in terms of health, demographic, social, psychological, etc. Weather modification management involves policies, methods, techniques and technologies that affect atmospheric features in order to make atmospheric water useful for humans, while eliminating its negative effects. Highly significant risk of natural disasters in Serbia is related to hailstorm disasters and droughts as atmospheric elementary disasters. The goal of this paper is to present certain methodologies and experience in Serbia in the weather modification management, mainly in the hailstorm processes. This paper provides analysis and critical review of the methodology of an action, with the analysis of the economic benefits. Cost-benefit analysis of a hail suppression project in Serbia was performed. The results point to the economic justification of some aspects of artificial influence on weather disasters.

  17. Global non-linear effect of temperature on economic production.

    Burke, Marshall; Hsiang, Solomon M; Miguel, Edward


    Growing evidence demonstrates that climatic conditions can have a profound impact on the functioning of modern human societies, but effects on economic activity appear inconsistent. Fundamental productive elements of modern economies, such as workers and crops, exhibit highly non-linear responses to local temperature even in wealthy countries. In contrast, aggregate macroeconomic productivity of entire wealthy countries is reported not to respond to temperature, while poor countries respond only linearly. Resolving this conflict between micro and macro observations is critical to understanding the role of wealth in coupled human-natural systems and to anticipating the global impact of climate change. Here we unify these seemingly contradictory results by accounting for non-linearity at the macro scale. We show that overall economic productivity is non-linear in temperature for all countries, with productivity peaking at an annual average temperature of 13 °C and declining strongly at higher temperatures. The relationship is globally generalizable, unchanged since 1960, and apparent for agricultural and non-agricultural activity in both rich and poor countries. These results provide the first evidence that economic activity in all regions is coupled to the global climate and establish a new empirical foundation for modelling economic loss in response to climate change, with important implications. If future adaptation mimics past adaptation, unmitigated warming is expected to reshape the global economy by reducing average global incomes roughly 23% by 2100 and widening global income inequality, relative to scenarios without climate change. In contrast to prior estimates, expected global losses are approximately linear in global mean temperature, with median losses many times larger than leading models indicate.

  19. Behavioral Effects in Forming the Preferences of the Economic Selection of the Economic Subject

    Svetlana, V. Belikova


    Full Text Available An attempt has been made to substantiate the behavioral features of the economic choice of an economic entity in the context of the decision-making environment transformation, and also to study their influence on the forming subjective preferences. At the same time, the behavioral paradigm is identified as a basic theoretical construct, which makes it possible to identify the main irrationalizing factors. Based on the study of the conceptual provisions of the behavioral paradigm, it was concluded that the preferences of the economic entity in the process of implementing the economic choice are formed under the influence of motivational and cognitive predictors, which limit the rationality of the economic entity. Deviating from rational criteria towards irrational, the economic entity shapes its preferences on the basis of economic and non-economic criteria, systematically making mistakes in the context of the influence of cognitive distortions manifested in decision-making under modern conditions. Based on the findings, the author constructs a model of economic choice, taking into account behavioral predictors. Among the most important cognitive distortions are herd instinct, professional deformation, "curse of knowledge", bias toward information retrieval, error of substantiation of assessment, bias of confirmation, neglect of formalized methods of cognition, conservatism, preferences of personified trust and heuristics of asymmetric perception.

  20. Analysis of the EU renewable energy directive by a techno-economic optimisation model

    Lind, Arne; Rosenberg, Eva; Seljom, Pernille; Espegren, Kari; Fidje, Audun; Lindberg, Karen


    The EU renewable energy (RES) directive sets a target of increasing the share of renewable energy used in the EU to 20% by 2020. The Norwegian goal for the share of renewable energy in 2020 is 67.5%, an increase from 60.1% in 2005. The Norwegian power production is almost solely based on renewable resources and the possibility to change from fossil power plants to renewable power production is almost non-existing. Therefore other measures have to be taken to fulfil the RES directive. Possible ways for Norway to reach its target for 2020 are analysed with a technology-rich, bottom-up energy system model (TIMES-Norway). This new model is developed with a high time resolution among others to be able to analyse intermittent power production. Model results indicate that the RES target can be achieved with a diversity of options including investments in hydropower, wind power, high-voltage power lines for export, various heat pump technologies, energy efficiency measures and increased use of biodiesel in the transportation sector. Hence, it is optimal to invest in a portfolio of technology choices in order to satisfy the RES directive, and not one single technology in one energy sector. - Highlights: • A new technology-rich, bottom-up energy system model is developed for Norway. • Possible ways for Norway to reach its renewable energy target for 2020 is analysed. • Results show that the renewable target can be achieved with a diversity of options. • The green certificate market contributes to increased investments in wind power

  1. Effects of the 2008 flood on economic performance and food security in Yemen: a simulation analysis.

    Breisinger, Clemens; Ecker, Olivier; Thiele, Rainer; Wiebelt, Manfred


    Extreme weather events such as floods and droughts can have devastating consequences for individual well being and economic development, in particular in poor societies with limited availability of coping mechanisms. Combining a dynamic computable general equilibrium model of the Yemeni economy with a household-level calorie consumption simulation model, this paper assesses the economy-wide, agricultural and food security effects of the 2008 tropical storm and flash flood that hit the Hadramout and Al-Mahrah governorates. The estimation results suggest that agricultural value added, farm household incomes and rural food security deteriorated long term in the flood-affected areas. Due to economic spillover effects, significant income losses and increases in food insecurity also occurred in areas that were unaffected by flooding. This finding suggests that while most relief efforts are typically concentrated in directly affected areas, future efforts should also consider surrounding areas and indirectly affected people. © 2016 The Author(s).

  2. Some economic effects of recent migration patterns on central cities.

    Sternlieb, G; Hughes, J W


    The authors examine demographic changes in central cities of the United States between 1970 and 1977 and the economic effects of these changes. Patterns of selective migration from central cities, particularly the general out-migration of the middle class and the recent return of the middle class to selected areas, are discussed. Changes in household and family patterns, racial composition, income, and poverty status are examined, and the aggregate impact of migration on resident incomes and purchasing power within central cities is analyzed. The findings show a continued concentration of poverty in central cities.

  3. Effects on social economics from transformations of the bioenergy system

    Braennlund, R.; Ankarhem, M.; Sjoestroem, M.; Marklund, P.O.; Lundgren, T.


    The transformation of the energy sector that is taking place in Sweden - substitution of renewable energy sources, in particular biofuels, for fossil fuels - will cause changes in the economy that are analysed in this report. The main issues are: How will the market be affected by a higher competition for wood? How will the fuel mix change in the heating sector? What environmental effects will result from the new energy policy? How will governmentally implemented economic incentives act on the fuel choices in the heating sector? Is the market for wood fuels efficient in the meaning that it reflects the values of the resource as the sellers and the buyers see it?

  4. Analysis of methods and models for assessing the direct and indirect economic impacts of CO/sub 2/-induced environmental changes in the agricultural sector of the US economy

    Callaway, J.M.; Cronin, F.J.; Currie, J.W.; Tawil, J.


    The overall purpose of this research was to assist the US Department of Energy (DOE) in developing methods for assessing the direct and indirect economic impacts due to the effects of increases in the ambient concentration of CO/sub 2/ on agricultural production. First, a comprehensive literature search was undertaken to determine what types of models and methods have been developed, which could be effectively used to conduct assessments of the direct and indirect economic impacts of CO/sub 2/ buildup. Specific attention was focused upon models and methods for assessing the physical impacts of CO/sub 2/-induced environmental changes on crop yields; national and multi-regional agricultural sector models; and macroeconomic models of the US economy. The second task involved a thorough investigation of the research efforts being conducted by other public and private sector organizations in order to determine how more recent analytical methods being developed outside of DOE could be effectively integrated into a more comprehensive analysis of the direct economic impacts of CO/sub 2/ buildup. The third and final task involved synthesizing the information gathered in the first two tasks into a systematic framework for assessing the direct and indirect economic impacts of CO/sub 2/-induced environmental changes originating in the agricultural sector of the US economy. It is concluded that the direct economic impacts of CO/sub 2/ on the agricultural sector and the indirect economic impacts caused by spillover effects from agriculture to other sectors of the economy will be pervasive; however, the direction and magnitude of these impacts on producers and consumers cannot be determined a priori.

  5. Causal relationships between energy consumption, foreign direct investment and economic growth: Fresh evidence from dynamic simultaneous-equations models

    Omri, Anis; Kahouli, Bassem


    This paper examines the interrelationships between energy consumption, foreign direct investment and economic growth using dynamic panel data models in simultaneous-equations for a global panel consisting of 65 countries. The time component of our dataset is 1990–2011 inclusive. To make the panel data analysis more homogenous, we also investigate this interrelationship for a number of sub-panels which are constructed based on the income level of countries. In this way, we end up with three income panels; namely, high income, middle income, and low income panels. In the empirical part, we draw on the growth theory and augment the classical growth model, which consists of capital stock, labor force and inflation, with foreign direct investment and energy. Generally, we show mixed results about the interrelationship between energy consumption, FDI and economic growth. - Highlights: • We examine the energy–FDI–growth nexus for a global panel of 65 countries. • Dynamic simultaneous-equation panel data models are used to address this issue. • We also investigate this nexus for three sub-panels which are constructed based on the income level of countries. • We show mixed results about the interrelationship between the three variables

  6. Resource engineering and economic studies for direct application of geothermal energy. Draft final report


    The feasibility of utilizing geothermal energy at a selected plant in New York State was studied. Existing oil and gas records suggests that geothermal fluid is available in the target area and based on this potential. Friendship Dairies, Inc., Friendship, NY, was selected as a potential user of geothermal energy. Currently natural gas and electricity are used as its primary energy sources. Six geothermal system configurations were analyzed based on replacement of gas or oil-fired systems for producing process heat. Each system was evaluated in terms of Internal Rate of Return on Investment (IRR), and simple payback. Six system configurations and two replaced fuels, representative of a range of situations found in the state, are analyzed. Based on the potential geothermal reserves at Friendship, each of the six system configurations are shown to be economically viable, compared to continued gas or oil-firing. The Computed IRR's are all far in excess of projected average interest rates for long term borrowings: approximately 15% for guarantee backed loans or as high as 20% for conventional financing. IRR is computed based on the total investment (equity plus debt) and cash flows before financing costs, i.e., before interest expense, but after the tax benefit of the interest deduction. The base case application for the Friendship analysis is case B/20 yr-gas which produces an IRR of 28.5% and payback of 3.4 years. Even better returns could be realized in the cases of oil-avoidance and where greater use of geothermal energy can be made as shown in the other cases considered.

  8. The effects of local government investment on economic growth and employment: evidence from transitional China

    Zhang Weiguo; Hou Yongjian


    Based on the panel data of 28 provinces in the year of 1987-2001,this paper examines the effects of the local government investment on economic growth and employment.The empirical result shows that the local government investment plays a significant positive role in economic growth and emplovment.However,while the proportion of local government investment to GDP had a remarkable rise after 1998.the elasticity of local government investment on economic growth declined,which shows that there is a hig room for raising the efficiency of local government mvestment.Moreover,the empirical examination shows that although local government investment had positive effect on employment,the elasticity had a decrease after 1994 when the tax-sharing system reform was put into practice.This shows that the positive role of local government investment on emplovment is also limited.This paper argues that the role of local governments as investors must be weakened,and local governments of different levels should lessen direct economic intervention and concentrate on public regulation.

  10. Biomass Direct Liquefaction Options. TechnoEconomic and Life Cycle Assessment

    Tews, Iva J.; Zhu, Yunhua; Drennan, Corinne; Elliott, Douglas C.; Snowden-Swan, Lesley J.; Onarheim, Kristin; Solantausta, Yrjo; Beckman, David


    The purpose of this work was to assess the competitiveness of two biomass to transportation fuel processing routes, which were under development in Finland, the U.S. and elsewhere. Concepts included fast pyrolysis (FP), and hydrothermal liquefaction (HTL), both followed by hydrodeoxygenation, and final product refining. This work was carried out as a collaboration between VTT (Finland), and PNNL (USA). The public funding agents for the work were Tekes in Finland and the Bioenergy Technologies Office of the U.S. Department of Energy. The effort was proposed as an update of the earlier comparative technoeconomic assessment performed by the IEA Bioenergy Direct Biomass Liquefaction Task in the 1980s. New developments in HTL and the upgrading of the HTL biocrude product triggered the interest in reinvestigating this comparison of these biomass liquefaction processes. In addition, developments in FP bio-oil upgrading had provided additional definition of this process option, which could provide an interesting comparison.

  11. The economics of direct-to-consumer advertising of prescription-only drugs: prescribed to improve consumer welfare?

    Morgan, Steven; Mintzes, Barbara; Barer, Morris


    According to economic theory, one might expect that the informational content of direct-to-consumer advertising of prescription-only drugs would improve consumers' welfare. However, contrasting the models of consumer and market behaviour underlying this theory with the realities of the prescription-only drug market reveals that this market is distinct in ways that render it unlikely that advertising will serve an unbiased and strictly informative function. A review of qualitative evidence regarding the informational content of drug advertising supports this conclusion. Direct-to-consumer prescription drug advertising concentrates on particular products, and features of those products, to the exclusion of others, and the information provided has frequently been found to be biased or misleading in regulatory and academic evaluations. Governments that have so far resisted direct-to-consumer advertising should invest in independent sources of evidence that could help consumers and professionals to better understand the risks and benefits of treating disease with alternative drug and non-drug therapies, rather than permitting direct-to-consumer prescription drug advertising.

  15. The economic effect and outcome of delaying oral food challenges.

    Couch, Christopher; Franxman, Tim; Greenhawt, Matthew


    Food specific IgE (sIgE) is a useful marker to assess predictability of oral food challenge (OFC) outcome. A threshold of less than 2 kUA/L for peanut, egg, and milk has been proposed as a 50% negative predictive value at which patients may pass an OFC. To assess the economic effect and outcome of delaying OFCs. A retrospective analysis was performed for peanut, egg, and milk OFCs conducted between 2001 and 2012 at a tertiary food allergy referral center. Delayed OFC was defined as greater than 12 months from the time the sIgE level became less than 2 kUA/L. Time to OFC was explored in association with skin prick test result (wheal size), OFC outcome, and the economic effect of delay. Of 319 challenges, 173 OFCs were delayed (54.2%) by a mean time of 35.5 months (range, 13-123 months) vs a mean time of 4.2 months in the 146 challenges that were not delayed (P care system.

  16. The macro-economic rebound effect and the UK economy

    Barker, Terry; Ekins, Paul; Foxon, Tim


    This paper examines the macroeconomic rebound effect for the UK economy arising from energy efficiency policies 2000-2010 using the macroeconomic model, MDM-E3. The literature distinguishes between three types of rebound effect: direct, indirect and economy-wide. The macroeconomic rebound effect considered here is the combination of the indirect and economy-wide effects. Policies for the domestic, business, commercial and public, and transport sectors of the economy are analysed for 2000-2010. Overall, the policies lead to a saving of about 8% of the energy, which would otherwise have been used and a reduction in CO 2 emissions of 10% (or 14 mtC) by 2010. There are also favourable macroeconomic effects: lower inflation and higher growth. We find that the macroeconomic rebound effect arising from UK energy efficiency policies for the period 2000-2010 is around 11% by 2010, averaged across sectors of the economy. When this is added to the (assumed) direct rebound effect of around 15%, this gives a total rebound effect of around 26% arising from these policies. Thus, the findings of the study support the argument that energy efficiency improvements for both consumers and producers, stimulated by policy incentives, will lead to significant reductions in energy demand and hence in greenhouse gas emissions

  17. Economic analysis of direct hydrogen PEM fuel cells in three near-term markets

    Mahadevan, K.; Stone, H.; Judd, K.; Paul, D.


    Direct hydrogen polymer electrolyte membrane fuel cells (H-PEMFCs) offer several near-term opportunities including backup power applications in state and local agencies of emergency response; forklifts in high throughput distribution centers; and, airport ground support equipment. This paper presented an analysis of the market requirements for introducing H-PEMFCs successfully, as well as an analysis of the lifecycle costs of H-PEMFCs and competing alternatives in three near-term markets. It also used three scenarios as examples of the potential for market penetration of H-PEMFCs. For each of the three potential opportunities, the paper presented the market requirements, a lifecycle cost analysis, and net present value of the lifecycle costs. A sensitivity analysis of the net present value of the lifecycle costs and of the average annual cost of owning and operating each of the H-PEMFC opportunities was also conducted. It was concluded that H-PEMFC-powered pallet trucks in high-productivity environments represented a promising early opportunity. However, the value of H-PEMFC-powered forklifts compared to existing alternatives was reduced for applications with lower hours of operation and declining labor rates. In addition, H-PEMFC-powered baggage tractors in airports were more expensive than battery-powered baggage tractors on a lifecycle cost basis. 9 tabs., 4 figs

  20. Effective development of the entities on the basis of forecasting of financial and economic activities

    I. I. Shanin


    Full Text Available In article, the questions connected with approach on effective development of industrial enterprises on the example of the furniture entities are considered. Effective development of the entities is directed to cost reduction in case of production and implementation of products, for improvement of indicators of financial and economic activities. The research is conducted on the example of the furniture entities of the Voronezh region and Krasnodar Krai. Any entity constantly uses these or those resources connected with material, labor and finance costs. All resources, which are consumed during a certain production cycle, create a cost budget or the expense plan of the entity, which are the most important economic indicators of activities of any entity. Not always at the entities the attention is properly paid to forecasting of production expenses for a further stage of functioning. Most the entities will organize the activities in such a way that current plans pass from year to year, and at the same time the alternative ways directed to cost reduction in case of production and further sales of products aren't considered. Any entity needs forecasting and planning of costs for the following production stages, for the purposes of innovative development and effective functioning of productive activity of the entity. First, it is necessary for assessment of opportunities when financing productive activity and for further scheduling of expenses, directed to cost reduction and cost reallocation. Having analysed activities of the entities and having studied accounting (financial records, it is revealed that at the entities in 2015 in comparison with 2014, there was a decrease in outputs, but at the same time, the loss is observed. Based on the carried-out analysis, on the example of financial and economic activities of JSC GRAFSKOYE and JSC GKMF, conclusions are drawn, cost reduction allowances in case of production are revealed, and recommendations in

  1. Reassessing the Aurignacian of Slovenia: techno-economic behaviour and direct dating of osseous projectile points.

    Moreau, Luc; Odar, Boštjan; Higham, Tom; Horvat, Aleksander; Pirkmajer, Darja; Turk, Peter


    The Palaeolithic of southern Central Europe has a long history of archaeological research. Particularly, the presence of numerous osseous projectile points in many early Upper Palaeolithic (EUP) assemblages in this region has attracted the attention of the international research community. However, the scarcity of properly identified and well-dated Aurignacian contexts represents an obstacle for investigation of the nature and timing of the Middle to Upper Palaeolithic transition. In this context, the question of whether Neandertals made Aurignacian osseous projectile points, either on their own or as a consequence of cultural interaction with anatomically modern humans (AMH), still remains an open issue. Here we reassess the EUP record of Slovenia by evaluating the Aurignacian character of the assemblages from Potočka zijalka, Mokriška jama and Divje babe I in the light of their suggested roots in the local Mousterian. We provide a comprehensive description of the lithic industry from Potočka zijalka, which represents one of the rare EUP assemblages of southern Central Europe with a representative number of lithic artefacts to be analysed from the perspective of lithic technology and raw material economy. Our re-analysis of the Slovenian assemblages is backed by a series of 11 new ultrafiltered collagen 14C dates obtained directly on associated osseous projectile points from the studied assemblages. The Aurignacian of Potočka zijalka underlines the remarkable consistency of the Early Aurignacian with low typo-technological variability across Europe, resulting from a marked dependence on transported toolkits and raw material conservation. The new radiocarbon determinations for the Aurignacian of Slovenia appear to post-date the 34-32 ka BP (thousands of years before present) threshold for the last Neandertals in the region. Although not falsified, the hypothesis of Aurignacian bone tools in southern Central Europe as a product of late Neandertals is not

  2. Effects of Genotypes on Economic Traits in Chinese Dairy Goats

    X. P. Yue


    Full Text Available The aim of this study was to investigate allele frequencies at the CSN1S2 locus in two Chinese dairy goat breeds and the effects of its variation on dairy goat economic traits. Seven hundred and eight goats from Xinong Saanen (XS, n = 268 and Guanzhong (GZ, N = 440 breeds were selected. The milk samples of 268 XS goats were collected during the middle of lactation, body size parameters (708 goats and daily milk yield (202 goats were registered. The RFLP (restriction fragment length polymorphism and SSCP (single strand conformation polymorphism were used to detect the polymorphisms in CSN1S2. The Hardy-Weinberg (HW equilibrium and the associations between body size, milk yield and composition and the genotypes were calculated. The results revealed that only A and F CSN1S2 alleles were found in the two Chinese dairy goat breeds. Allelic frequencies of A and F were 0.795, 0.205 and 0.739, 0.261 in Xinong Saanen and Guanzhong population respectively. Xinong Saanen breed was in Hardy-Weinberg equilibrium, while Guanzhong breed deviated from Hardy-Weinberg equilibrium (p<0.05. The association of polymorphism with economic traits indicated that the goats with FF genotype have higher milk fat and total solid concentration than those with AA and AF genotypes (p<0.05.

  5. The Social Effects of the Economic Transformation in India (An Attempt at Measurement and Evaluation

    Bywalec Grzegorz


    Full Text Available One of significant and, at the same time, challenging research problems in Economics is measuring the social effect of economic growth (development. Economic growth should never be treated a goal per se. It is rational provided that it brings effects such as, generally speaking, an improvement in the standard of living. However, this is not always the case. Social sciences, including Economics, have not developed any uniform methods of measuring and evaluating such effects yet.

  6. Economic impact of GM crops: the global income and production effects 1996-2012.

    Brookes, Graham; Barfoot, Peter


    A key part of any assessment of the global value of crop biotechnology in agriculture is an examination of its economic impact at the farm level. This paper follows earlier annual studies which examined economic impacts on yields, key costs of production, direct farm income and effects, and impacts on the production base of the four main crops of soybeans, corn, cotton and canola. The commercialization of genetically modified (GM) crops has continued to occur at a rapid rate, with important changes in both the overall level of adoption and impact occurring in 2012. This annual updated analysis shows that there have been very significant net economic benefits at the farm level amounting to $18.8 billion in 2012 and $116.6 billion for the 17-year period (in nominal terms). These economic gains have been divided roughly 50% each to farmers in developed and developing countries. GM technology have also made important contributions to increasing global production levels of the four main crops, having added 122 million tonnes and 230 million tonnes respectively, to the global production of soybeans and maize since the introduction of the technology in the mid-1990s.

  7. Economic impact of dengue illness and the cost-effectiveness of future vaccination programs in Singapore.

    Luis R Carrasco


    Full Text Available BACKGROUND: Dengue illness causes 50-100 million infections worldwide and threatens 2.5 billion people in the tropical and subtropical regions. Little is known about the disease burden and economic impact of dengue in higher resourced countries or the cost-effectiveness of potential dengue vaccines in such settings. METHODS AND FINDINGS: We estimate the direct and indirect costs of dengue from hospitalized and ambulatory cases in Singapore. We consider inter alia the impacts of dengue on the economy using the human-capital and the friction cost methods. Disease burden was estimated using disability-adjusted life years (DALYs and the cost-effectiveness of a potential vaccine program was evaluated. The average economic impact of dengue illness in Singapore from 2000 to 2009 in constant 2010 US$ ranged between $0.85 billion and $1.15 billion, of which control costs constitute 42%-59%. Using empirically derived disability weights, we estimated an annual average disease burden of 9-14 DALYs per 100 000 habitants, making it comparable to diseases such as hepatitis B or syphilis. The proportion of symptomatic dengue cases detected by the national surveillance system was estimated to be low, and to decrease with age. Under population projections by the United Nations, the price per dose threshold for which vaccines stop being more cost-effective than the current vector control program ranged from $50 for mass vaccination requiring 3 doses and only conferring 10 years of immunity to $300 for vaccination requiring 2 doses and conferring lifetime immunity. The thresholds for these vaccine programs to not be cost-effective for Singapore were $100 and $500 per dose respectively. CONCLUSIONS: Dengue illness presents a serious economic and disease burden in Singapore. Dengue vaccines are expected to be cost-effective if reasonably low prices are adopted and will help to reduce the economic and disease burden of dengue in Singapore substantially.

  9. Template-Directed Instrumentation Reduces Cost and Improves Efficiency for Total Knee Arthroplasty: An Economic Decision Analysis and Pilot Study.

    McLawhorn, Alexander S; Carroll, Kaitlin M; Blevins, Jason L; DeNegre, Scott T; Mayman, David J; Jerabek, Seth A


    Template-directed instrumentation (TDI) for total knee arthroplasty (TKA) may streamline operating room (OR) workflow and reduce costs by preselecting implants and minimizing instrument tray burden. A decision model simulated the economics of TDI. Sensitivity analyses determined thresholds for model variables to ensure TDI success. A clinical pilot was reviewed. The accuracy of preoperative templates was validated, and 20 consecutive primary TKAs were performed using TDI. The model determined that preoperative component size estimation should be accurate to ±1 implant size for 50% of TKAs to implement TDI. The pilot showed that preoperative template accuracy exceeded 97%. There were statistically significant improvements in OR turnover time and in-room time for TDI compared to an historical cohort of TKAs. TDI reduces costs and improves OR efficiency.

  10. Methanol as an alternative fuel: Economic and health effects

    Yuecel, M.K.


    Switching from gasoline to methanol fuels has important economic and health effects. Replacing gasoline with methanol will affect oil markets by lowering the demand for oil and thus lowering oil prices. Increased demand for the natural gas feedstock will increase natural gas prices. Because methanol is more costly than gasoline, fuel prices will also increase. On the other hand, methanol use will reduce ozone pollution and some of the health risks associated with gasoline. Considering all three markets affected by the phasing-out of gasoline, the switch to methanol results in net gains. The health benefits from lower pollution and the lives saved from the switch from gasoline to methanol are in addition to these gains. Overall, the benefits of the policy far outweigh the costs. However, the gains in the oil market, arising from the US monopsony power in the world oil market, can be captured by other, more efficient policies. 21 refs., 2 figs., 3 tabs

  11. Expansionary economic effects of energy conversion under stagnation

    Ono, Yoshiyasu


    After the Fukushima disaster, energy conversion such as nuclear power phaseout and deployment of renewable energy or survival of nuclear power had been actively argued pro and con. Both sides admitted extra costs were needed but their economic effects would be contrary dependent on business state. Under better economy, extra costs would be actual burden of total economy. Under stagnation as was long in Japan at present, extra costs brought about expansion of employment and economy with simulated consumption increase. Industry conversion would occur such industry intensively using power would depreciate and energy conserved industry would grow. Difference of power use intensity between industries made difficult in energy conversion because present Japanese industry constitution was mostly formed based on cheap power cost for industry use. Even taking account of international competition, the same would be true by adjusting finance balance sheet and currency exchange rate. (T. Tanaka)

  12. Effects of Economic Recession on Road Safety Indexes

    Rojo, M.; Gonzalo-Orden, H.; Linares, A.; Olio, L. dell’


    During the last years, the investment in both construction and conservation of transportinfrastructures has been considerably reduced in several countries, as Spain. After anumber of years in which economic circumstances have forced Governments to reducebudgets earmarked for the maintenance and creation of new ways, it is interesting toanalyze whether this has taken a toll on accident rates.The paper evaluates if there are significant changes in the road safety through these yearsin Spain, comparing the annual statistics concerning investment in infrastructure andaccidents. Thus, the classical risk, mortality and severity indexes have been analyzed tounderstand their real trends. Finally, through linear regression techniques, it is shown howthese trends are related to the budgets invested each year, in order to draw interestingconclusions about the effect of their reduction.

  13. Simulating economic effects of disruptions in the telecommunications infrastructure.

    Cox, Roger Gary; Barton, Dianne Catherine; Reinert, Rhonda K.; Eidson, Eric D.; Schoenwald, David Alan


    CommAspen is a new agent-based model for simulating the interdependent effects of market decisions and disruptions in the telecommunications infrastructure on other critical infrastructures in the U.S. economy such as banking and finance, and electric power. CommAspen extends and modifies the capabilities of Aspen-EE, an agent-based model previously developed by Sandia National Laboratories to analyze the interdependencies between the electric power system and other critical infrastructures. CommAspen has been tested on a series of scenarios in which the communications network has been disrupted, due to congestion and outages. Analysis of the scenario results indicates that communications networks simulated by the model behave as their counterparts do in the real world. Results also show that the model could be used to analyze the economic impact of communications congestion and outages.

    K.Yu. Polyak


    Full Text Available The paper deals with the study of scientific works on the issue of formation and development of organizational and methodological regulations of accounting and analytical support of the economic activity of an enterprise in emergencies, which led to the conclusion about the complex character of the study of theory, methodology and economic analysis of enterprises in various sectors of national economy. The author studies the approaches to the nature and methods of economic analysis that resulted in the presentation of instructional techniques to the economic structure. In assessing the consequences of emergencies, it is necessary to determine their impact on the indices of economic analysis; so, there was the need to define areas resulting index changes as a result of emergency situations by identifying its components which may affect emergencies. After analyzing the data, it was found that the consequences of emergency situations affecting the indices of business analysis and can lead to changes in management decisions of internal and external users.

  16. Effects of economic downturns on child mortality: a global economic analysis, 1981-2010.

    Maruthappu, Mahiben; Watson, Robert A; Watkins, Johnathan; Zeltner, Thomas; Raine, Rosalind; Atun, Rifat


    To analyse how economic downturns affect child mortality both globally and among subgroups of countries of variable income levels. Retrospective observational study using economic data from the World Bank's Development Indicators and Global Development Finance (2013 edition). Child mortality data were sourced from the Institute for Health Metrics and Evaluation. Global. 204 countries between 1981 and 2010. Child mortality, controlling for country-specific differences in political, healthcare, cultural, structural, educational and economic factors. 197 countries experienced at least 1 economic downturn between 1981 and 2010, with a mean of 7.97 downturns per country (range 0-21; SD 0.45). At the global level, downturns were associated with significant (p<0.0001) deteriorations in each child mortality measure, in comparison with non-downturn years: neonatal (coefficient: 1.11, 95% CI 0.855 to 1.37), postneonatal (2.00, 95% CI 1.61 to 2.38), child (2.93, 95% CI 2.26 to 3.60) and under 5 years of age (5.44, 95% CI 4.31 to 6.58) mortality rates. Stronger (larger falls in the growth rate of gross domestic product/capita) and longer (lasting 2 years rather than 1) downturns were associated with larger significant deteriorations (p<0.001). During economic downturns, countries in the poorest quartile experienced ∼1½ times greater deterioration in neonatal mortality, compared with their own baseline; a 3-fold deterioration in postneonatal mortality; a 9-fold deterioration in child mortality and a 3-fold deterioration in under-5 mortality, than countries in the wealthiest quartile (p<0.0005). For 1-5 years after downturns ended, each mortality measure continued to display significant deteriorations (p<0.0001). Economic downturns occur frequently and are associated with significant deteriorations in child mortality, with worse declines in lower income countries.

  17. Direct and indirect effects of radiation on polar solid solutions

    Ershov, V.G.; Gaponova, I.S.


    Radiation-chemical decomposition of a solute is due to the direct effect of ionizing radiation on it and also to its reaction with radical-ion products of radiolysis of the solution. At low temperature, the movement of the reagents is limited, and thus it is possible to isolate and evaluate the contribution of direct and indirect effects of radiation on the solute. The present paper is devoted to an investigation of the mechanism of formation of radicals from a solute (LiNO 2 ) in a polar solid solution (CH 3 OH) under the effect of γ-radiation

  1. The economic effect of Planet Health on preventing bulimia nervosa.

    Wang, Li Yan; Nichols, Lauren P; Austin, S Bryn


    To assess the economic effect of the school-based obesity prevention program Planet Health on preventing disordered weight control behaviors and to determine the cost-effectiveness of the intervention in terms of its combined effect on prevention of obesity and disordered weight control behaviors. On the basis of the intervention's short-term effect on disordered weight control behaviors prevention, we projected the number of girls who were prevented from developing bulimia nervosa by age 17 years. We further estimated medical costs saved and quality-adjusted life years gained by the intervention over 10 years. As a final step, we compared the intervention costs with the combined intervention benefits from both obesity prevention (reported previously) and prevention of disordered weight control behaviors to determine the overall cost-effectiveness of the intervention. Middle schools. A sample of 254 intervention girls aged 10 to 14 years. The Planet Health program was implemented during the school years from 1995 to 1997 and was designed to promote healthful nutrition and physical activity among youth. Intervention costs, medical costs saved, quality-adjusted life years gained, and cost-effectiveness ratio. An estimated 1 case of bulimia nervosa would have been prevented. As a result, an estimated $33 999 in medical costs and 0.7 quality-adjusted life years would be saved. At an intervention cost of $46 803, the combined prevention of obesity and disordered weight control behaviors would yield a net savings of $14 238 and a gain of 4.8 quality-adjusted life years. Primary prevention programs, such as Planet Health, warrant careful consideration by policy makers and program planners. The findings of this study provide additional argument for integrated prevention of obesity and eating disorders.

    Khakzar Bafrooei F.


    Full Text Available Pretreatment of cotton fabric with poly(propylene imine dendrimer enhanced its colour strength using C.I. Direct Red 81 and C.I. Direct Blue 78. Application of this dendrimer and the direct dye simultaneously on cotton fabric by the exhaust and the continuous dyeing method were studied; slight improvements in the dyeing results were obtained. Pretreatment of the cotton fabric with dendrimer in an emulsion form using the pad-dry method followed by continuous dyeing markedly increased the colour strength. In addition, level dyeing was obtained, and no negative effects on the fastness properties of the dyes used were observed.

  3. [Clinical effectiveness and economical evaluation of preventive vaccination].

    Vaz Carneiro, António; Belo, Ana Isabel; Gouveia, Miguel; Costa, João; Borges, Margarida


    The value of mass vaccination as a preventive measure for infectious diseases is one of the most important advances of modern Medicine. The impact on incidence of several infectious diseases, until recently responsible for significant morbidity and mortality at world level, is well proved in a series of high quality epidemiological studies. In this scientific review we aimed firstly to briefly resume the history of mass vaccination and its scientists, responsible for synthesis and marketing of these drugs. In second place we present a group of a few disease preventable by vaccines as well as the Portuguese National Vaccination Plan and its benefits. In third place we identified groups of subjects in which a well structured vaccination plan is particularly important, as well as the correspondent diseases to be covered by vaccination. Fourthly, we discussed the ethical considerations of vaccination, and its tensions between subject autonomy and society advantages in com pulsive programs. Fifthly, we analyzed clinical effectiveness of vaccines through the concept of herd immunity, clinical evaluation of immune response to vaccines and some examples of systematic reviews on three relevant diseases (influenza, meningococcal and pneumococcal infections). In sixth place we discussed vaccine safety presenting monitoring methods of vaccination risks, as well as discussing the public myths concerning vaccines. Finally we present a economic analysis of preventive vaccination with a review of some published literature on specific diseases. We conclude that mass vaccination is a efficacious preventive measure, as well as a economic rational choice, and that this public health intervention should be a pillar of a modern preventive system.

  5. Effect of economic parameters on power generation expansion planning

    Sevilgen, Sueleyman Hakan; Hueseyin Erdem, Hasan; Cetin, Burhanettin; Volkan Akkaya, Ali; Dagdas, Ahmet


    The increasing consumption of electricity within time forces countries to build additional power plants. Because of technical and economic differences of the additional power plants, economic methodologies are used to determine the best technology for the additional capacity. The annual levelized cost method is used for this purpose, and the technology giving the minimum value for the additional load range is chosen. However, the economic parameters such as interest rate, construction escalation, fuel escalation, maintenance escalation and discount factor can affect the annual levelized cost considerably and change the economic range of the plants. Determining the values of the economical parameters in the future is very difficult, especially in developing countries. For this reason, the analysis of the changing rates of the mentioned values is of great importance for the planners of the additional capacity. In this study, the changing rates of the economic parameters that influence the annual levelized cost of the alternative power plant types are discussed. The alternative power plants considered for the electricity generation sector of Turkey and the economic parameters dominating each plant type are determined. It is clearly seen that the annual levelized cost for additional power plants varies with the economic parameters. The results show that the economic parameters variation has to be taken into consideration in electricity generation planning

  7. Thrust and jet directional control using the Coanda effect

    Alexandru DUMITRACHE


    Full Text Available The application of the Coandă effect to the directional control of a jet or thrust is presented. Deviation of the thrust force by direct flow can be achieved by using the Coandă effect to change the angle of the primary jet engine exhaust nozzle. Major interest in the study of this phenomenon is caused by the possibility of using this effect for aircrafts with short take-off and landing, for thrust vectoring. The numerical investigations are performed using a RANS solver with an adequate turbulence model, showing a change of the jet direction. Thus, the conditions and the limits within which one can benefit from the advantages of Coandă-type flows are determined.

  8. Physical energy cost serves as the 'invisible hand' governing economic valuation. Direct evidence from biogeochemical data and the U.S. metal market

    Liu, Zhicen; Koerwer, Joel; Nemoto, Jiro; Imura, Hidefumi


    Energy supply is mandatory for the production of economic value. Nevertheless, tradition dictates that an enigmatic 'invisible hand' governs economic valuation. Physical scientists have long proposed alternative but testable energy cost theories of economic valuation, and have shown the gross correlation between energy consumption and economic output at the national level through input-output energy analysis. However, due to the difficulty of precise energy analysis and highly complicated real markets, no decisive evidence directly linking energy costs to the selling prices of individual commodities has yet been found. Over the past century, the US metal market has accumulated a huge body of price data, which for the first time ever provides us the opportunity to quantitatively examine the direct energy-value correlation. Here, by analyzing the market price data of 65 purified chemical elements (mainly metals) relative to the total energy consumption for refining them from naturally occurring geochemical conditions, we found a clear correlation between the energy cost and their market prices. The underlying physics we proposed has compatibility with conventional economic concepts such as the ratio between supply and demand or scarcity's role in economic valuation. It demonstrates how energy cost serves as the 'invisible hand' governing economic valuation. Thorough understanding of this energy connection between the human economic and the Earth's biogeochemical metabolism is essential for improving the overall energy efficiency and furthermore the sustainability of the human society.

  10. Effect of cavitation in high-pressure direct injection

    Aboulhasanzadeh, Bahman; Johnsen, Eric


    As we move toward higher pressures for Gasoline Direct Injection and Diesel Direct Injection, cavitation has become an important issue. To better understand the effect of cavitation on the nozzle flow and primary atomization, we use a high-order accurate Discontinuous Galerkin approach using multi-GPU parallelism to simulate the compressible flow inside and outside the nozzle. Phase change is included using the six-equations model. We investigate the effect of nozzle geometry on cavitation inside the injector and on primary atomization outside the nozzle.

    Full Text Available The article explores the prospects for the development of Ukraine’s anti-crisis strategy in the current conditions of aggravation of the socio-economic situation. The urgency of the researched subject – namely, the study of the potential directions for the development of the anti-crisis tools of Ukrainian state policy – is determined primarily by the seriousness of the problem, which should be overcome by means of these methods. The purpose of the article is to identify promising tools and mechanisms for an anti-crisis policy that can make a significant contribution to improving the current state of the socio-economic sphere in Ukraine. Its subject is anti-crisis tools and instruments, which could be used in Ukrainian scenario. It is noted that our state is at the stage of the permanent crisis and suffers from the consequences of both global and local crisis phenomena. The scientific novelty of the article is determined by the combination of economic, social, political, and legal approaches to the study of the current state of the Ukrainian economy. The methodology of the research is formed by the combination of economic and political methods of scientific activities, which are based on the principles of objectivism and systematic approach. The findings of scientific research and recommendations of some Ukrainian scientists regarding the necessary anti-crisis tools are considered as the sources for the article. The results of the study show that Ukraine suffers from a series of systemic problems and challenges, which are the main threat to the stability of the national economy. Among the most influential of them we can identify the low level of incomes of citizens, which is associated with the devaluation of the national currency and the increase in utility tariffs; high level of unemployment; shortage of foreign and domestic investments; the decline in production and exports, caused both by military operations in the Donbas and the loss

    The objective of this study was to examine the relationship of work loss associated with gastro- the relationship of work loss associated with gastro- the relationship of work loss associated with gastro-esophageal reflux disease (GERD) and peptic ulcer disease (GERD) and peptic ulcer disease (PUD) in a large population of employed individuals in the United States (US) and quantify the individuals in the United States (US) and quantify the economic impact of these diseases to the employer. A proprietary database that contained work place absence, disability and workers' compensation data in addition to prescription drug and medical claims was used to answer the objectives. Employees with a medical claim with an ICD-9 code for GERD or PUD were identified from 1 January 1997 to 31 December 2000. A cohort of controls was identified for the same time period using the method of frequency matching on age, gender, industry type, occupational status, and employment status. Work absence rates and health care costs were compared between the groups after adjusting for demo graphic, and employment differences using analysis of covariance models. There were significantly lower (p rate of adjusted all-cause absenteeism and sickness-related absenteeism were observed between the disease groups versus the controls. In particular, controls had an average of 1.2 to 1.6 days and 0.4 to 0.6 lower all-cause and sickness-related absenteeism compared to the disease groups. The incremental economic impact projected to a hypothetical employed population was estimated to be $3441 for GERD, $1374 for PUD, and $4803 for GERD + PUD per employee per year compared to employees without these diseases. Direct medical cost and work absence in employees with GERD, PUD and GERD + PUD represent a significant burden to employees and employers.

  17. Uncertainty and Sensitivity of Direct Economic Flood Damages: the FloodRisk Free and Open-Source Software

    Albano, R.; Sole, A.; Mancusi, L.; Cantisani, A.; Perrone, A.


    The considerable increase of flood damages in the the past decades has shifted in Europe the attention from protection against floods to managing flood risks. In this context, the expected damages assessment represents a crucial information within the overall flood risk management process. The present paper proposes an open source software, called FloodRisk, that is able to operatively support stakeholders in the decision making processes with a what-if approach by carrying out the rapid assessment of the flood consequences, in terms of direct economic damage and loss of human lives. The evaluation of the damage scenarios, trough the use of the GIS software proposed here, is essential for cost-benefit or multi-criteria analysis of risk mitigation alternatives. However, considering that quantitative assessment of flood damages scenarios is characterized by intrinsic uncertainty, a scheme has been developed to identify and quantify the role of the input parameters in the total uncertainty of flood loss model application in urban areas with mild terrain and complex topography. By the concept of parallel models, the contribution of different module and input parameters to the total uncertainty is quantified. The results of the present case study have exhibited a high epistemic uncertainty on the damage estimation module and, in particular, on the type and form of the utilized damage functions, which have been adapted and transferred from different geographic and socio-economic contexts because there aren't depth-damage functions that are specifically developed for Italy. Considering that uncertainty and sensitivity depend considerably on local characteristics, the epistemic uncertainty associated with the risk estimate is reduced by introducing additional information into the risk analysis. In the light of the obtained results, it is evident the need to produce and disseminate (open) data to develop micro-scale vulnerability curves. Moreover, the urgent need to push

  18. Measuring macro-level effects of the global economic recession on university-industry research cooperation

    Azagra-Caro, J.M.; Tijssen, R.J.W.; Yegros-Yegros, A.


    The 2007/2008 financial crisis, and ensuing economic recession, had a direct negative effect on university-industry research cooperation in the OECD countries and other economies – it diminished the number of university-industry co-authored research publications (UICs) during the period 2008-13 by 7%. It also changed the relationship between national business expenditure on R&D and UIC output levels. Before the recession the relationship was negative, but became positive during the years 2008-2013. The few countries where business expenditure on R&D increased during recession saw UIC numbers rise. This moderating effect of the recession applies only to ‘domestic UICs’, where universities cooperated with business companies located in the same country. Micro-level research is needed to assess the contributing effects on large university-industry R&D consortia on both domestic and international collaboration patterns. (Author)

  19. Direct and Indirect Effects of PM on the Cardiovascular System

    Nelin, Timothy D.; Joseph, Allan M.; Gorr, Matthew W.; Wold, Loren E.


    Human exposure to particulate matter (PM) elicits a variety of responses on the cardiovascular system through both direct and indirect pathways. Indirect effects of PM on the cardiovascular system are mediated through the autonomic nervous system, which controls heart rate variability, and inflammatory responses, which augment acute cardiovascular events and atherosclerosis. Recent research demonstrates that PM also affects the cardiovascular system directly by entry into the systemic circulation. This process causes myocardial dysfunction through mechanisms of reactive oxygen species production, calcium ion interference, and vascular dysfunction. In this review, we will present key evidence in both the direct and indirect pathways, suggest clinical applications of the current literature, and recommend directions for future research.

  20. A new way to estimate the direct and indirect rebound effect and other rebound indicators

    Freire-González, Jaume


    Some progress has been done during the last years on the methods and provision of empirical evidence on the direct and indirect rebound effect. However, these methods are complex, and sometimes require some specific economic knowledge. The development of risk and vulnerability rebound indicators for economies can be a useful tool to help the research community, policy-makers and other practitioners to understand and tackle the rebound effect. This research shows a new analytical way to obtain the direct and indirect rebound effect from the direct rebound effect and the use of energy input-output coefficients, and proposes three risk and vulnerability rebound indicators to show the effects of energy efficiency improvements in households on overall energy consumption. An estimation of these indicators has been conducted for the EU-27 countries. - Highlights: • A new method to estimate direct and indirect rebound effect is shown. • Three indicators are developed to assess risk and vulnerability to rebound. • An estimation of rebound indicators has been carried out for the EU-27 economies.

    Full Text Available The purpose of the paper is to substantiate, on the real figures, the need for enterprise’s financial and economic activities analysis as a condition of management decisions making to achieve the success of the company. Methodology. The research is based on a comparison and analysis of data from the organization top management. So using matrix analysis in the paper, the financial and economic activities effectiveness is evaluated. Based on these calculations, it is possible to make conclusions about the necessity of an identified management decisions regarding the future activity of the company. Results. Daily managers of various function levels accept hundreds and thousands of decisions regarding seemingly slight problems of the organization in general. At the same time, every such a decision, especially relating to the activity of the whole structure, should be clearly justified. Such a need stems from the fact that every decision leads to certain consequences. If there is a need to make a decision relating to the future of the enterprise (e.g., embodiment, reorganization, etc., it should be based on the data of the entire structure. And that is generally very difficult to do. Many factors complicate the possibility of comprehensive evaluation of the company’s activity. At the same time, analysis of basic indicators will provide the specialist with some directions according to which the priority of the analysis can be indicated and appropriate management decision can be made. Practical implications. It is built an effectiveness matrix of financial and economic activities of the enterprise. Analysis of financial and economic activities makes it possible to design necessary strategic and tactical plan for the enterprise development, revealing its reserves of production efficiency increasing. So the aim of the paper is the assessment of the effectiveness of financial and economic activities of the company on the base of matrix analysis as a

  2. Economic evaluation of nuclear reactor operation utilizing power effect

    Budinsky, M.; Mydliar, J.


    The operation of a reactor at the so-called power effect may substantially increase the burnup of fuel to be removed. The aim of the evaluation of such reactor operation is the optimal determination of the time over which the yield of the higher use of fuel exceeds economic losses resulting from the increased share of constant expenditure of the price of generated kWh of electric power which ensues from such operation. A mathematical model is presented for such evaluation of reactor operation with regard to benefits for the national economy which is the basis of the ESTER 2 computer program. The calculations show that the prices of generated and delivered kWh are minimally 2% less than the prices of generated power without the power effect use. The minimum ranges in the interval of 30 to 50 days. The dependence of the price of generated and delivered kWh from the point of view of the operator of the power plant as well as the component of fuel price of generated kWh will not reach the minimum even after 50 days of operation. From the operating and physical points of view the duration of power effect is not expected to exceed 20 to 30 days which means that from the point of view of the national economy the price of generated and delivered kWh will be 1.6 to 2% less and the fuel component of the price of the generated kWh will be 3 to 4.5% lower.

    Lee, Gun Sun; Kim, Jin Soo; Seo, Yo Seob; Kim, Jae Duk [School of Dentistry, Oral Biology Research Institute, Chosun University, Gwangju (Korea, Republic of)


    This study aimed to provide comparative measurements of the effective dose from direct and indirect digital panoramic units according to phantoms and exposure parameters. Dose measurements were carried out using a head phantom representing an average man (175 cm tall, 73.5 kg male) and a limbless whole body phantom representing an average woman (155 cm tall, 50 kg female). Lithium fluoride thermoluminescent dosimeter (TLD) chips were used for the dosimeter. Two direct and 2 indirect digital panoramic units were evaluated in this study. Effective doses were derived using 2007 International Commission on Radiological Protection (ICRP) recommendations. The effective doses of the 4 digital panoramic units ranged between 8.9 {mu}Sv and 37.8 {mu}Sv. By using the head phantom, the effective doses from the direct digital panoramic units (37.8 {mu}Sv, 27.6 {mu}Sv) were higher than those from the indirect units (8.9 {mu}Sv, 15.9 {mu}Sv). The same panoramic unit showed the difference in effective doses according to the gender of the phantom, numbers and locations of TLDs, and kVp. To reasonably assess the radiation risk from various dental radiographic units, the effective doses should be obtained with the same numbers and locations of TLDs, and with standard hospital exposure. After that, it is necessary to survey the effective doses from various dental radiographic units according to the gender with the corresponding phantom.

  4. Economic and Water Supply Effects of Ending Groundwater Overdraft in California's Central Valley

    Timothy Nelson


    Full Text Available doi: water and groundwater management are often tightly linked, even when linkage is not intended or expected. This link is especially common in semi-arid regions, such as California. This paper summarizes a modeling study on the effects of ending long-term overdraft in California’s Central Valley, the state’s largest aquifer system. The study focuses on economic and operational aspects, such as surface water pumping and diversions, groundwater recharge, water scarcity, and the associated operating and water scarcity costs. This analysis uses CALVIN, a hydro-economic optimization model for California’s water resource system that suggests operational changes to minimize net system costs for a given set of conditions, such as ending long-term overdraft. Based on model results, ending overdraft might induce some major statewide operational changes, including large increases to Delta exports, more intensive conjunctive-use operations with increasing artificial and in-lieu recharge, and greater water scarcity for Central Valley agriculture. The statewide costs of ending roughly 1.2 maf yr-1 of groundwater overdraft are at least $50 million per year from additional direct water shortage and additional operating costs. At its worst, the costs of ending Central Valley overdraft could be much higher, perhaps comparable to the recent economic effects of drought. Driven by recent state legislation to improve groundwater sustainability, ending groundwater overdraft has important implications statewide for water use and management, particularly in the Sacramento–San Joaquin Delta. Ending Central Valley overdraft will amplify economic pressure to increase Delta water exports rather than reduce them, tying together two of California’s largest water management problems.

  5. Economics of mycotoxins: evaluating costs to society and cost-effectiveness of interventions.


    The economic impacts of mycotoxins to human society can be thought of in two ways: (i) the direct market costs associated with lost trade or reduced revenues due to contaminated food or feed, and (ii) the human health losses from adverse effects associated with mycotoxin consumption. Losses related to markets occur within systems in which mycotoxins are being monitored in the food and feed supply. Food that has mycotoxin levels above a particular maximum allowable level is either rejected outright for sale or sold at a lower price for a different use. Such transactions can take place at local levels or at the level of trade among countries. Sometimes this can result in heavy economic losses for food producers, but the benefit of such monitoring systems is a lower risk of mycotoxins in the food supply. Losses related to health occur when mycotoxins are present in food at levels that can cause illness. In developed countries, such losses are often measured in terms of cost of illness; around the world, such losses are more frequently measured in terms of disability-adjusted life years (DALYs). It is also useful to assess the economics of interventions to reduce mycotoxins and their attendant health effects; the relative effectiveness of public health interventions can be assessed by estimating quality-adjusted life years (QALYs) associated with each intervention. Cost-effectiveness assessment can be conducted to compare the cost of implementing the intervention with the resulting benefits, in terms of either improved markets or improved human health. Aside from cost-effectiveness, however, it is also important to assess the technical feasibility of interventions, particularly in low-income countries, where funds and infrastructures are limited.

  6. Directional effects in transitional resonance spectra and group constants

    Hill, R.N.; Oh, K.O.; Rhodes, J.D.


    Analytical exploratory investigations indicate that transition effects such as streaming cause a considerable spatial variation in the neutron spectra across resonances; streaming leads to opposite effects in the forward and backward directions. The neglect of this coupled spatial/angular variations of the transitory resonance spectra is an approximation that is common to all current group constant generation methodologies. This paper presents a description of the spatial/angular coupling of the neutron flux across isolated resonances. It appears to be necessary to differentiate between forward-and backward-directed neutron flux components or even to consider components in narrower angular cones. The effects are illustrated for an isolated actinide resonance in a simplified fast reactor blanket problem. The resonance spectra of the directional flux components φ + and φ - , and even more so the 90-deg cone components, are shown to deviate significantly from the infinite medium approximation, and the differences increase with penetration. The charges in φ + lead to a decreasing scattering group constant that enhances neutron transmission; the changes in φ - lead to an increasing group constant inhibiting backward scattering. Therefore, the changes in the forward-and backward-directed spectra both lead to increased neutron transmission. Conversely, the flux (φ = φ + +φ - ) is shown to agree closely with the infinite medium approximation both in the analytical formulas and in the numerical solution. The directional effect cancel in the summation. The forward-and backward-directed flux components are used as weighting spectra to illustrate the group constant changes for a single resonance

    Full Text Available Clause is devoted to an actual problem of decrease in negative consequences of technological development of key economic branches of the industry at a regional level. During social and economic transformations to Russia to the beginning of 90th years XX of a century there has been begun complex process of re-structuring of key economic branches of the industry, including technological, social and economic transformations. During re-structuring by one of key directions of the decision of existing social problems there is a formation of effective policy of support of small business at a regional and local level. Creation of favorable conditions for development of small business allows for short time and at rather low expenses to smooth disproportions of social and economic development of territories arising at re-structuring. Flexibility inherent in small business, mobility and adaptibility to changeable market conditions can promote the decision of problems of social stability, maintenance of employment and saturation of the consumer market. Creation of the enterprises of small business on the basis of local natural-economic resources raises social and economic potential of industrial territories.

  16. On the treatment of exchange effects in direct reactions

    Bencze, Gy.


    In the theoretical description of direct nuclear reactions the dynamic effects are combined with 'kinematical' effects due to the quantum mechanical exchange interaction caused by the Pauli principle governing the mechanics of identical particles. In the present paper it is shown that in the frame of general algebraic theory of identical particle scattering the effects of the permutational symmetry of nucleons can be separated on an exact way from the treatment of reaction dynamics. Dynamical approximations may be used only after the separation of permutational effects. (D.Gy.)

  17. Total, direct, and indirect effects of paan on oral cancer.

    Merchant, Anwar T; Pitiphat, Waranuch


    Paan (betel leaf and betel nut quid) used with or without tobacco has been positively associated with oral cancer. Oral submucous fibrosis (OSMF), a precancerous condition caused by paan, lies on the causal pathway between paan use and oral cancer. The purpose of this analysis was to estimate the effect of paan consumption on oral cancer risk when it is mediated by OSMF. We used mediation methods proposed by VanderWeele, which are based on causal inference principles, to characterize the total, direct, and indirect effects of paan, consumed with and without tobacco, on oral cancer mediated by OSMF. We reanalyzed case-control data collected from three hospitals in Karachi, Pakistan, between July 1996 and March 1998. For paan without tobacco, the total effect on oral cancer was OR 7.39, 95 % CI 1.01, 38.11, the natural indirect effect (due to OSMF among paan users) was OR 2.48, 95 % CI 0.99, 10.44, and the natural direct effect (due to paan with OSMF absent) was OR 3.32, 95 % CI 0.68, 10.07. For paan with tobacco, the total direct effect was OR 15.68, 95 % CI 3.00, 54.90, the natural indirect effect was OR 2.18, 95 % CI 0.82, 5.52, and the natural direct effect was OR 7.27, 95 % CI 2.15, 20.43. Paan, whether or not it contained tobacco, raised oral cancer risk irrespective of OSMF. Oral cancer risk was higher among those who used paan with tobacco.

  18. Economic impact

    Technology Transfer Department


    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.

  19. Directly alcohol-attributable mortality by industry and occupation in a Spanish Census cohort of economically active population.

    Pulido, José; Vallejo, Fernando; Alonso-López, Ignacio; Regidor, Enrique; Villar, Fernando; de la Fuente, Luis; Domingo-Salvany, Antonia; Barrio, Gregorio


    To assess disparities in directly alcohol-attributable (DAA) mortality by industry/occupation in Spain during 2002-2011 and the contribution of different socio-demographic factors, including socioeconomic position, to explain such disparity. Nationwide cohort study covering 16 million economically active people living in Spain in 2001. Deaths at age 25-64 were analyzed. Subjects were classified by employment status, industry and occupation at baseline. Poisson regression models were built, calculating rate ratios (RRs) compared to all employees or those in the education sector. DAA mortality was much higher in the unemployed than in employees (Crude RR: 2.4; 95% CI: 2.3-2.6) and varied widely across industries/occupations. Crude RRs>3.0 (pindustries/fishing, agriculture/livestock, construction, catering/accommodation and protective services. Socio-demographic factors, especially age, gender and educational attainment contributed more to explain risk disparities than other factors or potential selection bias. However, after exhaustive sociodemographic adjustment, including education attainment and material wealth, a RR>1.33 (p<0.05) remained in unemployed, catering/accommodation employees and unskilled construction workers. RRs were significantly larger in women than men (p<0.05) among mineworkers/fishworkers/sailors (RR=8.6 vs. 1.2) and drivers (RR=3.7 vs. 1.0). The results could be extrapolated to all alcohol-attributable mortality since disparities for other strongly alcohol-related deaths, although smaller, were in the same direction. Given the wide occupational disparities in alcohol-attributable mortality, implementation of special measures to reduce this mortality in the highest risk groups is fully justified. Future research should better characterize the explanatory factors of disparities and their role in the causal chain. Copyright © 2017. Published by Elsevier B.V.

  20. Passive seismic monitoring of natural and induced earthquakes: case studies, future directions and socio-economic relevance

    Bohnhoff, Marco; Dresen, Georg; Ellsworth, William L.; Ito, Hisao; Cloetingh, Sierd; Negendank, Jörg


    An important discovery in crustal mechanics has been that the Earth’s crust is commonly stressed close to failure, even in tectonically quiet areas. As a result, small natural or man-made perturbations to the local stress field may trigger earthquakes. To understand these processes, Passive Seismic Monitoring (PSM) with seismometer arrays is a widely used technique that has been successfully applied to study seismicity at different magnitude levels ranging from acoustic emissions generated in the laboratory under controlled conditions, to seismicity induced by hydraulic stimulations in geological reservoirs, and up to great earthquakes occurring along plate boundaries. In all these environments the appropriate deployment of seismic sensors, i.e., directly on the rock sample, at the earth’s surface or in boreholes close to the seismic sources allows for the detection and location of brittle failure processes at sufficiently low magnitude-detection threshold and with adequate spatial resolution for further analysis. One principal aim is to develop an improved understanding of the physical processes occurring at the seismic source and their relationship to the host geologic environment. In this paper we review selected case studies and future directions of PSM efforts across a wide range of scales and environments. These include induced failure within small rock samples, hydrocarbon reservoirs, and natural seismicity at convergent and transform plate boundaries. Each example represents a milestone with regard to bridging the gap between laboratory-scale experiments under controlled boundary conditions and large-scale field studies. The common motivation for all studies is to refine the understanding of how earthquakes nucleate, how they proceed and how they interact in space and time. This is of special relevance at the larger end of the magnitude scale, i.e., for large devastating earthquakes due to their severe socio-economic impact.

The survey is based on research, conducted for 60 companies in the spring of 2015 (32% of which were Ukrainian and 68% – offices and affiliates of international companies, namely Bayer, Coca-Cola, Pepsi Co, Mondelez, Mars, Mintel, Cargill, and many others. The practical results of monitoring the effectiveness of annual plans of named companies done by authors through implementing original author’ methodology based on presenting key performance indicators (KPI. Results. The theoretical approaches to the estimation of marketing efficiency are analysed. The conditions, under which the organization is working by analysing external environment and internal company’s potential, are determined. It is substantiated by the authors that direct development of marketing plans should be based on marketing objectives, developed as a result of the situational analysis. It is proved that monitoring the effectiveness of annual plans may be done by implementing key performance indicators that enable to develop quantitative evaluation system of the organization’s strategy, based on control of its goals. The results of the research allowed authors to distinguish two major groups of effectiveness indicators for TNCs, which are financial and marketing indicators. In this standpoint, financial indicators are divided into costs’, productivity and profitability indicators and to the marketing effectiveness indicators belong market indexes, competitiveness indexes, and client’s indicators. Practical implications. The proposed methodology can be implemented for the qualitative and quantitative estimation of marketing effectiveness not only in TNCs but in small and medium business companies as well

  4. Art viewing directives in hospital settings effect on mood.

    Ho, Rainbow T H; Potash, Jordan S; Fang, Fan; Rollins, Judy


    The purpose of this study was to determine the effect viewing directives can have when encountering art in hospitals. A secondary objective of the study was to understand the responses of viewers to an art exhibit on the theme of medical student empathy toward patient pain and suffering. Displaying art in hospitals has been credited with increasing well-being of patients, visitors, and staff. Generally, hospital curators have focused on the type of art to display (natural, symbolic, and abstract). This focus has neglected the possibility that in addition to the type of art, the way that viewers engage art may also be responsible for the healing effect. Participants (n = 97) were randomly allocated into one of the viewing directives: (1) reflecting on one artwork, (2) creating a drawing or poem in response to one artwork, or (3) no direction. Prior to looking at the art and immediately after, participants were administered the Brief Mood Introspection Scale (BMIS) and offered an opportunity to participate in an interview. Pre-post results of the BMIS demonstrated that viewers who received directions achieved some therapeutic effect. Qualitative themes from the post-exhibit interviews identified that the empathy themed exhibit was well received, although there were differences among responses from patients, visitors, and staff. The results imply that hospitals may consider offering prompts to help viewers engage with art to enhance mood and exhibiting art that demonstrates empathy for patient suffering. © The Author(s) 2015.

    Lya Aklimawati


    Full Text Available Economic cluster approach can be used to enhance economic growth of a region by optimizing local resources. Coffee is one of plantation commodity which is developed in Bondowoso district through economic cluster model. Low quality coffee beans and inefficiency marketing system were the basic problems at farmer level that pushed for developing economic coffee cluster. The aim of this research was to analyze the effect of service quality on economic coffee cluster development toward farmers and stakeholders satisfaction. This research was carried out at Bondowoso District, East Java. Direct observation and interviews coffee farmers and stakeholders using closed questions was conducted in this study. Data collected consisted of primary and secondary data. The number of respondents were 47 stakeholders consisted of 5 bank officers, 5 officers from district plantation service, 2 officers from foresty company and 35 farmers. Respondens selection was based on convenience sampling method. Primary data was analyzed by using correlation and multiple linear regression analysis. The result showed that the relationship between dimensions of service quality with each other varies from weak to strong. Stakeholders satisfaction (included farmers on economic coffee cluster implementation was influenced significantly by tangible. While reliability, responsiveness, assurance and empathy had no effect on stakeholders satisfaction.

  6. An overview of current research on EU ETS: Evidence from its operating mechanism and economic effect

    Zhang, Yue-Jun; Wei, Yi-Ming


    The European Union Emissions Trading Scheme (EU ETS) is supposed to be an important mechanism for addressing climate change. Up to now, the theoretical foundation of EU ETS has been widely acknowledged, but empirical research on its current situation has only been published recently or is forthcoming. Therefore, this paper is aimed to summarize the main arguments of empirical studies on the EU ETS, in terms of two aspects, i.e., the operating mechanism and economic effect of the EU ETS, which are two crucial topics and have been attached much attention. Based on the shortcomings of current research and future requirements of the EU ETS evolution, finally, we also present some further directions of the EU ETS research. Overall, the research overview here may be helpful to recognize the features of the EU ETS and its effect on others. (author)

  9. Parent socialization effects in different cultures: significance of directive parenting.

    Sorkhabi, Nadia


    In this article, the controversy of divergent findings in research on parental socialization effects in different cultures is addressed. Three explanations intended to address divergent findings of socialization effects in different cultures, as advanced by researchers who emphasize cultural differences, are discussed. These include cultural differences in socialization values and goals of parents, parental emotional and cognitive characteristics associated with parenting styles, and adolescents' interpretations or evaluations of their parents' parenting styles. The empirical evidence for and against each of these arguments is examined and an alternative paradigm for understanding and empirical study of developmental outcomes associated with parenting styles in different cultures is suggested. Baumrind's directive parenting style is presented as an alternative to the authoritarian parenting style in understanding the positive developmental effects associated with "strict" parenting in cultures said to have a collectivist orientation. Directions for research on the three explanations are mentioned.

  10. Influence of Gaze Direction on Face Recognition: A Sensitive Effect

    Noémy Daury


    Full Text Available This study was aimed at determining the conditions in which eye-contact may improve recognition memory for faces. Different stimuli and procedures were tested in four experiments. The effect of gaze direction on memory was found when a simple “yes-no” recognition task was used but not when the recognition task was more complex (e.g., including “Remember-Know” judgements, cf. Experiment 2, or confidence ratings, cf. Experiment 4. Moreover, even when a “yes-no” recognition paradigm was used, the effect occurred with one series of stimuli (cf. Experiment 1 but not with another one (cf. Experiment 3. The difficulty to produce the positive effect of gaze direction on memory is discussed.

  11. The direct piezoelectric effect in the globular protein lysozyme

    Stapleton, A.; Noor, M. R.; Sweeney, J.; Casey, V.; Kholkin, A. L.; Silien, C.; Gandhi, A. A.; Soulimane, T.; Tofail, S. A. M.


    Here, we present experimental evidence of the direct piezoelectric effect in the globular protein, lysozyme. Piezoelectric materials are employed in many actuating and sensing applications because they can convert mechanical energy into electrical energy and vice versa. Although originally studied in inorganic materials, several biological materials including amino acids and bone, also exhibit piezoelectricity. The exact mechanisms supporting biological piezoelectricity are not known, nor is it known whether biological piezoelectricity conforms strictly to the criteria of classical piezoelectricity. The observation of piezoelectricity in protein crystals presented here links biological piezoelectricity with the classical theory of piezoelectricity. We quantify the direct piezoelectric effect in monoclinic and tetragonal aggregate films of lysozyme using conventional techniques based on the Berlincourt Method. The largest piezoelectric effect measured in a crystalline aggregate film of lysozyme was approximately 6.5 pC N-1. These findings raise fundamental questions as to the possible physiological significance of piezoelectricity in lysozyme and the potential for technical applications.

  12. Direct probe of dark energy through gravitational lensing effect

    He, Hong-Jian [T. D. Lee Institute, and School of Physics and Astronomy, Shanghai Jiao Tong University, Shanghai 200240 (China); Zhang, Zhen, E-mail:, E-mail: [Center for High Energy Physics, Peking University, Beijing 100871 (China)


    We show that gravitational lensing can provide a direct method to probe the nature of dark energy at astrophysical scales. For lensing system as an isolated astrophysical object, we derive the dark energy contribution to gravitational potential as a repulsive power-law term, containing a generic equation of state parameter w . We find that it generates w -dependent and position-dependent modification to the conventional light orbital equation of w =−1. With post-Newtonian approximation, we compute its direct effect for an isolated lensing system at astrophysical scales and find that the dark energy force can deflect the path of incident light rays. We demonstrate that the dark-energy-induced deflection angle Δα{sub DE}∝ M {sup (1+1/3} {sup w} {sup )} (with 1+1/3 w > 0), which increases with the lensing mass M and consistently approaches zero in the limit M → 0. This effect is distinctive because dark energy tends to diffuse the rays and generates concave lensing effect . This is in contrast to the conventional convex lensing effect caused by both visible and dark matter. Measuring such concave lensing effect can directly probe the existence and nature of dark energy. We estimate this effect and show that the current gravitational lensing experiments are sensitive to the direct probe of dark energy at astrophysical scales. For the special case w =−1, our independent study favors the previous works that the cosmological constant can affect light bending, but our prediction qualitatively and quantitatively differ from the literature, including our consistent realization of Δα{sub DE} → 0 (under 0 M → ) at the leading order.

  13. The behavioral economics of social anxiety disorder reveal a robust effect for interpersonal traits.

    Rodebaugh, Thomas L; Tonge, Natasha A; Weisman, Jaclyn S; Lim, Michelle H; Fernandez, Katya C; Bogdan, Ryan


    Recent evidence suggests that reduced generosity among individuals with social anxiety disorder (SAD) in behavioral economic tasks may result from constraint in changing behavior according to interpersonal contingencies. That is, people with SAD may be slower to be more generous when the situation warrants. Conversely, more global effects on generosity may be related to interpersonal vindictiveness, a dimension only somewhat related to SAD. A total of 133 participants, 73 with the generalized form of SAD, completed self-report instruments and a behavioral economic task with simulated interpersonal (friend, romantic partner, stranger) interactions. In a separate visit, friends (n = 88) also came to the lab and rated participants on vindictiveness. Interpersonal vindictiveness was associated with reduced initial and overall giving to simulated friends. SAD predicted a lack of increased giving to a simulated friend, and attenuated an increase in giving to simulated known versus unknown players compared to participants without SAD. Friend-reported vindictiveness predicted in the same direction as diagnosis. However, the findings for SAD were less robust than those for vindictiveness. SAD is perhaps weakly related to behavioral constraint in economic tasks that simulate interpersonal interactions, whereas vindictiveness is strongly related to lower overall generosity as well as (via friend report) behavioral constraint. Further study is needed to better characterize the construct of vindictiveness. Our findings dovetail with the suggestion that SAD is related to impairment in the proposed affiliation and attachment system, but further suggest that direct study of that system may be more fruitful than focusing on disorders.

  14. The direct and indirect effects of corruption on motor vehicle crash deaths.

    Hua, Law Teik; Noland, Robert B; Evans, Andrew W


    Recent empirical research has found that there is an inverted U-shaped or Kuznets relationship between income and motor vehicle crash (MVC) deaths, such that MVC deaths increase as national income increases and decrease after reaching a critical level. Corruption has been identified as one of the underlying factors that could affect this relationship, primarily by undermining institutional development and effective enforcement schemes. The total effect of corruption can be decomposed into two components, a direct and an indirect effect. The direct effect measures the immediate impact of corruption on MVC deaths by undermining effective enforcement and regulations, while the indirect effect captures the impact of corruption on hindering increases in per capita income and the consequent impact of reduced income on MVC deaths. By influencing economic growth, corruption can lead to an increase or decrease in MVC deaths depending on the income level. Using data from 60 countries between 1982 and 2003, these effects are estimated using linear panel and fixed effects negative binomial models. The estimation results suggest that corruption has different direct effects for less developed and highly developed countries. It has a negative (decreasing) effect on MVC deaths for less developed countries and a positive (increasing) effect on MVC deaths for highly developed countries. For highly developed countries, the total effect is positive at lower per capita income levels, but decreases with per capita income and becomes negative at per capita income levels of about US$ 38,248. For less developed countries, the total effect is negative within the sample range and decreases with increased per capita income. In summary, the results of this study suggest that reduction of corruption is likely a necessary condition to effectively tackle road safety problems. 2010 Elsevier Ltd. All rights reserved.

    David Alan Aschauer


    This paper contains an investigation of the effects of different means of financing government spending on economic growth, inflation, and welfare. In this setting, two different types of government spending are considered: productive expenditures which provide services to the private sector in its production activities; and unproductive expenditures which have no direct influence on the private economy. In turn, two different forms of finance are considered: proportional income taxation; and...

  16. Economic and demographic effects on working women in Latin America.

    Psaharopoulos, G; Tzannatos, Z


    This analysis of women's work conditions in Latin America includes a description of general trends in female labor force participation in 15 Latin American countries based on census data between 1950 and 1990. Also examined are pay differentials by gender and whether gender alone or individual characteristics of women workers accounted for the sex-wage gap. More extensive treatment is available in the author's other 1992 publications. Trends indicate that marriage and children were important factors determining whether women were in the labor force or not. The probability of being in the labor force was reduced by 50% for married women, and each child reduced the probability by 5%. When marriage and children were controlled for, age had a positive effect on probability of participation. Urban female heads of household had a positive effect on women's labor force participation. The higher a woman's educational qualification, the greater the probability of being in the work force. Earnings increased with increased educational level. An increase of 1 year of schooling for women contributed to an increase in female earnings of 13.1. Investment in education for women has a higher yield for women than for men. Policies that directly or indirectly improve women's employment opportunities, particularly when families are being formed, can have wide distributional effects. Also unresolved was an explanation for why female participation increased during periods of recession and why women are rewarded more for educational effort than men. The suggestion was that public sector employment, which included many women in the labor force, is distorting results.

    Park, Jong Nam; Park, Kyung Won; Kim, Ji Hong; Kim, Jin O [Hanyang University (Korea, Republic of)


    This paper presents a new approach on genetic algorithm to economic dispatch problem for valve point discontinuities. Proposed approach in this paper on genetic algorithms improves the performance to solve economic dispatch problem for valve point discontinuities through improved death penalty method, generation-apart elitism, atavism and sexual selection with sexual distinction. Numerical results on a test system consisting of 13 thermal units show that the proposed approach is faster, more robust and powerful than conventional genetic algorithms.

    Blaustein, Andrew R.; Walls, Susan C.; Bancroft, Betsy A.; Lawler, Joshua J.; Searle, Catherine L.; Gervasi, Stephanie S.


    As part of an overall decline in biodiversity, populations of many organisms are declining and species are being lost at unprecedented rates around the world. This includes many populations and species of amphibians. Although numerous factors are affecting amphibian populations, we show potential direct and indirect effects of climate change on amphibians at the individual, population and community level. Shifts in amphibian ranges are predicted. Changes in climate may affect survival, growth...

  19. The cost-effectiveness of direct-to-consumer advertising for prescription drugs.

    Atherly, Adam; Rubin, Paul H


    In this paper we use published information to analyze the economic value of Direct to Consumer Advertising (DTCA). The reviewed research finds that DTCA leads to increased demand for the advertised drug and that the effect of the drug tends to be class-wide rather than product specific. There is weak evidence that DTCA may increase compliance and improve clinical outcomes. However, there is little research on the effect of DTCA on inappropriate prescribing or on the characteristics of patients who respond to treatment. On net, if the advertised drugs are cost effective on average and the patients using the drugs in response to the advertisement are similar to other users, DTCA is likely cost effective. Overall, the literature to date is consistent with the idea that DTCA is beneficial, but further research is needed before definitive conclusions can be drawn.

  20. Effect of direction on loudness for wideband and reverberant sounds

    Sivonen, Ville Pekka; Ellermeier, Wolfgang


    The effect of incidence angle on loudness was investigated for wideband and reverberant sounds. In an adaptive procedure, five listeners matched the loudness of a sound coming from five incidence angles in the horizontal plane to that of the same sound with frontal incidence. The stimuli were...... presented to the listeners via individual binaural synthesis. The results confirm that loudness depends on sound incidence angle, as it does for narrow-band, anechoic sounds. The directional effects, however, were attenuated with the wideband and reverberant stimuli used in the present investigation....

    Full Text Available Foreign Direct Investment (FDI is considered by researchers as a critical factor for economic growth and development since they have shown a positive relationship between FDI and economic growth. The recent economic crisis in the European Union (EU has brought up again the discussion of the key drivers specific to the attraction of FDI. In addition to strict economic factors the literature emphasizes the role of institutions in a country as determinants in attracting FDI inflows. An analysis of the role that the quality of institutions in attracting FDI has in Greece is attempted using an econometric model on institutional, regulatory, country specific and firm level data. For the purpose of giving a regional dimension in the analysis, and for attempting a comparison of the findings, the analysis focuses besides Greece, in two other Southeastern European countries (SEE, Bulgaria and Romania, being two new member states of the EU.

  5. Effects of economics and demographics on global fisheries sustainability.

    Ding, Qi; Wang, Yali; Chen, Xinjun; Chen, Yong


    A good understanding of social factors that lead to marine ecological change is important to developing sustainable global fisheries. We used balanced panel models and conducted cross-national time-series analyses (1970-2010) of 122 nations to examine how economic prosperity and population growth affected the sustainability of marine ecosystems. We used catches in economic exclusive zone (EEZ); mean trophic level of fishery landings (MTL); primary production required to sustain catches (expressed as percentage of local primary production [%PPR]); and an index of ecosystem overfishing (i.e., the loss in secondary production index [L index]) as indicators of ecological change in marine ecosystems. The EEZ catch, %PPR, and L index declined gradually after gross domestic product (GDP) per capita reached $15,000, $14,000, and $19,000, respectively, and MTL increased steadily once GDP per capita exceeded $20,000. These relationships suggest that economic growth and biodiversity conservation are compatible goals. However, increasing human populations would degrade marine ecosystems. Specifically, a doubling of human population caused an increase in the %PPR of 17.1% and in the L index of 0.0254 and a decline in the MTL of 0.176. A 1% increase in human population resulted in a 0.744% increase in EEZ catch. These results highlight the importance of considering social and economic factors in developing sustainable fisheries management policy. © 2016 Society for Conservation Biology.

    Claudia Loredana JUNCU


    Full Text Available The re-launching of the Romanian economy in the context of the world economic crisis can be implemented by using a set of principles and economic measures that will lead to a strict monetary policy, a fiscal and budgetary discipline as well as a reduction of the inflation. This paper presents a series of reforms that Romania needs in the present context, to start the process of re-launching the economy that is currently in a significant descending trend. It is necessary that all the economic and political actors participate actively in progressively meeting the competitive conditions of the Comunitary economies. Corrective, stimulating and functional measures need to be undertaken to permit the applicability towards all the actors that define the structure of the economic environment. The application and enforcement of the needed anti-crisis measures will determine a stop of the decline and the creation of the premises to economical re-launching.

  10. A method for analysing secondary economic effects generated by big research centres.

    Bianchi-Streit, M.; Budde, R.; Reitz, H.; Sagnell, B.; Schmied, H.; Schorr, B.

    Research activities in the natural sciences, and especially those in the field of pure research work as opposed to applied research, are being financially supported for various reasons, probably the least of which is the hope for a quick economic return. It has, nevertheless, been realised for a number of years that benefits of one sort or another may appear in various and sometimes unexpected ways, where these be— nefits are not the direct consequence of the applica— tion of a research result. They are rather to be com— pared with the well—known ”spin—off” effects obtained while pursuing the research work. An example may help to illustrate what is meant.

  11. The Time Delays’ Effects on the Qualitative Behavior of an Economic Growth Model

    Carlo Bianca


    Full Text Available A further generalization of an economic growth model is the main topic of this paper. The paper specifically analyzes the effects on the asymptotic dynamics of the Solow model when two time delays are inserted: the time employed in order that the capital is used for production and the necessary time so that the capital is depreciated. The existence of a unique nontrivial positive steady state of the generalized model is proved and sufficient conditions for the asymptotic stability are established. Moreover, the existence of a Hopf bifurcation is proved and, by using the normal form theory and center manifold argument, the explicit formulas which determine the stability, direction, and period of bifurcating periodic solutions are obtained. Finally, numerical simulations are performed for supporting the analytical results.

  12. The Effect of Direction on Cursor Moving Kinematics

    Chiu-Ping Lu


    Full Text Available There have been only few studies to substantiate the kinematic characteristics of cursor movement. In this study, a quantitative experimental research method was used to explore the effect of moving direction on the kinematics of cursor movement in 24 typical young persons using our previously developed computerized measuring program. The results of multiple one way repeated measures ANOVAs and post hoc LSD tests demonstrated that the moving direction had effects on average velocity, movement time, movement unit and peak velocity. Moving leftward showed better efficiency than moving rightward, upward and downward from the kinematic evidences such as velocity, movement unit and time. Moreover, the unique pattern of the power spectral density (PSD of velocity (strategy for power application explained why the smoothness was still maintained while moving leftward even under an unstable situation with larger momentum. Moreover, the information from this cursor moving study can guide us to relocate the toolbars and icons in the window interface, especially for individuals with physical disabilities whose performances are easily interrupted while controlling the cursor in specific directions.

  13. Modelling Common Agricultural Policy-Water Framework Directive interactions and cost-effectiveness of measures to reduce nitrogen pollution.

    Mouratiadou, Ioanna; Russell, Graham; Topp, Cairistiona; Louhichi, Kamel; Moran, Dominic


    Selecting cost-effective measures to regulate agricultural water pollution to conform to the Water Framework Directive presents multiple challenges. A bio-economic modelling approach is presented that has been used to explore the water quality and economic effects of the 2003 Common Agricultural Policy Reform and to assess the cost-effectiveness of input quotas and emission standards against nitrate leaching, in a representative case study catchment in Scotland. The approach combines a biophysical model (NDICEA) with a mathematical programming model (FSSIM-MP). The results indicate only small changes due to the Reform, with the main changes in farmers' decision making and the associated economic and water quality indicators depending on crop price changes, and suggest the use of target fertilisation in relation to crop and soil requirements, as opposed to measures targeting farm total or average nitrogen use.

  14. Direct-to-consumer advertising: its effects on stakeholders.

    Montoya, Isaac D; Lee-Dukes, Gwen; Shah, Dhvani


    The escalating growth in the development of pharmaceutical drugs has caused the pharmaceutical industry to market drugs directly to consumers. Direct-to-consumer (DTC) advertising has increased immensely in the past 15 years and continues to grow each year. The advantages of DTC advertising include an increase in consumer knowledge, patient autonomy, and possibly providing physicians and pharmacists with up-to-date information about the recent trends in the marketplace. However, there is also an equally notable list of disadvantages, which include concerns about the quality of information provided, loss in physician productivity due to time spent convincing patients that what they want is not in their best interest, and increases in the reimbursement expenditure of the insurers. Because of these conflicting outcomes, the issue of DTC advertising has become controversial. This report offers an overview of DTC advertising and focuses on its effects on physicians, pharmacists, consumers, insurers, the government, and pharmaceutical manufacturers.

A.; Zhang, J.


    We examine the consequences of the effective field theory (EFT) of dark matter–nucleon scattering for current and proposed direct detection experiments. Exclusion limits on EFT coupling constants computed using the optimum interval method are presented for SuperCDMS Soudan, CDMS II, and LUX, and the necessity of combining results from multiple experiments in order to determine dark matter parameters is discussed. We demonstrate that spectral differences between the standard dark matter model and a general EFT interaction can produce a bias when calculating exclusion limits and when developing signal models for likelihood and machine learning techniques. We also discuss the implications of the EFT for the next-generation (G2) direct detection experiments and point out regions of complementarity in the EFT parameter space.

  16. Direct and indirect effects of organizational justice on work ability.

    Spanier, K; Radoschewski, F M; Gutenbrunner, C; Bethge, M


    Organizational justice (OJ), involving transparent workplace procedures and treating staff members with respect, has been of growing concern in recent epidemiological research as a determinant of health-related outcomes. To examine the factorial validity of the German version of Moorman's Organizational Justice Questionnaire (OJQ), to investigate the direct cross-sectional effect of OJ on self-rated work ability and to analyse if there is an additional indirect effect of OJ on work ability mediated by effort-reward imbalance. An analysis of cross-sectional data from the Second German Sociomedical Panel of Employees, involving white-collar workers employed at least half time. We performed confirmatory factor analyses to test the factorial validity of the OJQ and analysed the direct and indirect associations of OJ and self-rated work ability by path model analysis. Of the 1217 participants (47% female; mean age: 51) 36% had poor work ability. Factor analyses confirmed the two-factor structure of the German OJQ. Work ability was explained directly by OJ (β = 0.30) and effort-reward imbalance (β = -0.27). Additionally, we identified an indirect effect of OJ that was mediated by effort-reward imbalance (β = 0.14). The total effect of OJ on work ability was remarkably strong (β = 0.44). Associations remained unchanged after adjustment for socio-demographic parameters. This study showed the importance of considering additional indirect pathways when examining the impact of OJ on the work ability of employees. © The Author 2014.

  17. The Economic Effect of Competition in the Air Transportation Industry

    Hubbard, H. B.


    The air transportation industry has been described as a highly-competitive, regulated oligopoly or as a price-regulated cartel with blocked entry, resulting in excessive service and low load factors. The current structure of the industry has been strongly influenced by the hypotheses that increased levels of competition are desirable per se, and that more competing carriers can be economically supported in larger markets, in longer haul markets, with lower unit costs, and with higher fare levels. An elementary application of competition/game theory casts doubt on the validity of these hypotheses, but rather emphasizes the critical importance of the short-term non-variable costs in determining economic levels of competition.

  18. Fertilizing growth: Agricultural inputs and their effects in economic development.

    McArthur, John W; McCord, Gordon C


    This paper estimates the role of agronomic inputs in cereal yield improvements and the consequences for countries' processes of structural change. The results suggest a clear role for fertilizer, modern seeds and water in boosting yields. We then test for respective empirical links between agricultural yields and economic growth, labor share in agriculture and non-agricultural value added per worker. The identification strategy includes a novel instrumental variable that exploits the unique economic geography of fertilizer production and transport costs to countries' agricultural heartlands. We estimate that a half ton increase in staple yields generates a 14 to 19 percent higher GDP per capita and a 4.6 to 5.6 percentage point lower labor share in agriculture five years later. The results suggest a strong role for agricultural productivity as a driver of structural change.

    Lejour, Arjan Marcel; Mervar, Andrea; Verweij, Gerard


    We explore the economic implications of Croatia's possible accession to the European Union. We focus on two main changes associated with the EU-membership: accession to the internal European Market and institutional reforms in Croatia triggered by the EU-membership. GDP per capita in Croatia is estimated to rise by about 1.1 percent as a result of accession to the internal market. In particular the textile and wearing apparel sectors expand. If Croatia succeeds in reforming its domestic insti...

  20. Assessing the economic effects of Latin American independence

    Prados de la Escosura, Leandro


    This paper discusses the economic consequences of independence in Latin America. Grand interpretations that assess Nineteenth Century Latin America by comparison to the U.S. performance are examined and the alternative approach of using African and Asian post-colonial experiences as the yardstick is explored. Empirical evidence on the consequences of removing the colonial burden and opening up to the international economy is, then, examined. The paper concludes with discussion of when Latin A...

  6. The Economic Crisis and Several Effects on Global Economy

    Florina BRAN


    Full Text Available The main mechanism of profit making is not production according to the outcomes of several analyses of the current economic crisis. This mechanism is circulation and exchange. Starting with this observation the paper goes through a number of aspects regarding the relation between crisis and economy at global level. These aspects consist in the recent financial turmoil; who pays for the crisis; stabilizing the financial sector; recession and the financial crisis; the internationalization of the crisis; commodities and the ecological crisis; an end to neo-liberalism; what should socialists demand. We notice and comment on how important current development in the wake of the banking crisis is for the transmission of that crisis to the rest of the economy and its interaction with the more general economic crisis now emerging. It was concluded that there are good chances that the current economic order to be broken. The future shape of the order will depend more on vision of managers than on the influence of the so called objective factors.

  7. Are adverse effects incorporated in economic models? An initial review of current practice.

    Craig, D; McDaid, C; Fonseca, T; Stock, C; Duffy, S; Woolacott, N


    To identify methodological research on the incorporation of adverse effects in economic models and to review current practice. Major electronic databases (Cochrane Methodology Register, Health Economic Evaluations Database, NHS Economic Evaluation Database, EconLit, EMBASE, Health Management Information Consortium, IDEAS, MEDLINE and Science Citation Index) were searched from inception to September 2007. Health technology assessment (HTA) reports commissioned by the National Institute for Health Research (NIHR) HTA programme and published between 2004 and 2007 were also reviewed. The reviews of methodological research on the inclusion of adverse effects in decision models and of current practice were carried out according to standard methods. Data were summarised in a narrative synthesis. Of the 719 potentially relevant references in the methodological research review, five met the inclusion criteria; however, they contained little information of direct relevance to the incorporation of adverse effects in models. Of the 194 HTA monographs published from 2004 to 2007, 80 were reviewed, covering a range of research and therapeutic areas. In total, 85% of the reports included adverse effects in the clinical effectiveness review and 54% of the decision models included adverse effects in the model; 49% included adverse effects in the clinical review and model. The link between adverse effects in the clinical review and model was generally weak; only 3/80 (manipulation. Of the models including adverse effects, 67% used a clinical adverse effects parameter, 79% used a cost of adverse effects parameter, 86% used one of these and 60% used both. Most models (83%) used utilities, but only two (2.5%) used solely utilities to incorporate adverse effects and were explicit that the utility captured relevant adverse effects; 53% of those models that included utilities derived them from patients on treatment and could therefore be interpreted as capturing adverse effects. In total

The paper aims to test several econometric models to explain the relationship between human capital and economic output. Using World Bank data, 17 countries with the fastest e...

  10. The health economics of ankle and foot sprains and fractures: A systematic review of English-language published papers. Part 2: The direct and indirect costs of injury.

    Bielska, Iwona A; Wang, Xiang; Lee, Raymond; Johnson, Ana P


    Ankle and foot sprains and fractures are prevalent injuries, which may result in substantial physical and economic consequences for the patient and place a financial burden on the health care system. Therefore, the objectives of this paper are to examine the direct and indirect costs of treating ankle and foot injuries (sprains, dislocations, fractures), as well as to provide an overview of the outcomes of full economic analyses of different treatment strategies. A systematic review was carried out among seven databases to identify English language publications on the health economics of ankle and foot injury treatment published between 1980 and 2014. The direct and indirect costs were abstracted by two independent reviewers. All costs were adjusted for inflation and reported in 2016 US dollars (USD). Among 2047 identified studies, 32 were selected for analysis. The direct costs of ankle sprain management ranged from $292 to $2268 per patient (2016 USD), depending on the injury severity and treatment strategy. The direct costs of managing ankle fractures were higher ($1908-$19,555). Foot fracture treatment had similar direct costs ranging from $998 to $21,801. The economic evaluations were conducted from the societal or payer's perspectives. The costs of treating ankle and foot sprains and fractures varied among the studies, mostly due to differences in injury type and study characteristics, which impacted the ability of directly comparing the financial burden of treatment. Nonetheless, the review showed that the costs experienced by the patient and the health care system increased with injury complexity. Copyright © 2017 Elsevier Ltd. All rights reserved.

  11. Direct and indirect effects of body weight on adult wages.

    Han, Euna; Norton, Edward C; Powell, Lisa M


    Previous estimates of the association between body weight and wages in the literature have been conditional on education and occupation. In addition to the effect of current body weight status (body mass index (BMI) or obesity) on wages, this paper examines the indirect effect of body weight status in the late-teenage years on wages operating through education and occupation choice. Using the National Longitudinal Survey of Youth 1979 data, for women, we find that a one-unit increase in BMI is directly associated with 1.83% lower hourly wages whereas the indirect BMI wage penalty is not statistically significant. Neither a direct nor an indirect BMI wage penalty is found for men. However, results based on clinical weight classification reveal that the indirect wage penalty occurs to a larger extent at the upper tail of the BMI distribution for both men and women via the pathways of education and occupation outcomes. Late-teen obesity is indirectly associated with 3.5% lower hourly wages for both women and men. These results are important because they imply that the total effect of obesity on wages is significantly larger than has been estimated in previous cross-sectional studies. 2011 Elsevier B.V.

  12. Effect-directed analysis: Current status and future challenges

    Hong, Seongjin; Giesy, John P.; Lee, Jung-Suk; Lee, Jong-Hyeon; Khim, Jong Seong


    Effect-directed analysis (EDA) has become useful for identification of toxicant(s) that occur in mixtures in the environment, especially those that are causative agents of specific adverse effects. Here, we summarize and review EDA methodology including preparation of samples, biological analyses, fractionations, and instrumental analyses, highlighting key scientific advancements. A total of 63 documents since 1999 (Scopus search) including 46 research articles, 13 review papers, and 4 project descriptions, have been collected and reviewed in this study. At the early stage (1999-2010), most studies that applied EDA focused on organic extracts of freshwater and coastal contaminated sediments and wastewater. Toxic effects were often measured using cell-based bioassays ( in vitro) and the causative chemicals were identified by use of low resolution gas chromatography with mass selective detector (GCMSD). More recently (2010-present), EDA has been extended to various matrices such as biota, soil, crude oil, and suspended solids and techniques have been improved to include determination of bioavailability in vivo. In particular, methods for non-target screenings of organic chemicals in environmental samples using cutting-edge instrumentation such as time of flight-mass spectrometry (ToF-MS), Fourier transform-ion cyclotron resonance (FT-ICR), and Orbitrap mass spectrometer have been developed. This overview provides descriptions of recent improvements of EDA and suggests future research directions based on current understandings and limitations.

  13. Effect-directed analysis supporting monitoring of aquatic ...

    Aquatic environments are often contaminated with complex mixtures of chemicals that may pose a risk to ecosystems and human health. This contamination cannot be addressed with target analysis alone but tools are required to reduce this complexity and identify those chemicals that might cause adverse effects. Effect-directed analysis (EDA) is designed to meet this challenge and faces increasing interest in water and sediment quality monitoring. Thus, the present paper summarizes current experience with the EDA approach and the tools required,and provides practical advice on their application. The paper highlights the need for proper problem formulation and gives general advice for study design. As the EDA approach is directed by toxicity, basic principles for the selection of bioassays are given as well as a comprehensive compilation of appropriate assays, includingtheir strengths andweaknesses. A specific focus is given to strategies for sampling, extraction and bioassay dosing since they strongly impact prioritization of toxicants in EDA. Reduction of sample complexity mainly relies onfractionation procedures, which are discussed in this paper, including quality assurance and quality control. Automated combinations of fractionation, biotesting and chemical analysis using so-called hyphenated tools can enhance the throughput and might reduce the risk of artifacts in laboratory work. The key to determiningthe chemical structures causing effects is analytical toxi

  14. Modeling of Social Effect of Foreign Direct Investment in The Regions of Kazakhstan

    Dinara Zhaksylykovna Rakhmatullayeva


    Full Text Available In the article, the authors estimated the social effect of foreign direct investments (FDI in the regions of Kazakhstan. In order to do it, the authors studied the dynamics of FDI of the region operating enterprises with foreign participation and the regional six indicators of socio-economic development during 2003-2013 on the basis of database of RK Agency on statistics. There are 16 regions of Kazakhstan were involved in the experiment (14 provinces and 2 cities of republican significant — Almaty and Astana. The research was carried out using the “simplified” version of the T. Saati’s Analytic Hierarchy Process (AHP mathematical apparatus and MS Excel. The constructed economic-mathematical model of an assessment of FDI impact on the population welfare and living quality in the regions was hypothetical as the expert estimates of hypothetical expert were used. The authors made a hypothesis: to receive tools for an assessment of the social effect of FDI in the regions of Kazakhstan — the Rating of regional priority of the factors (RPF Rating. The RPF Rating allowed to define a priority of the factors of the population welfare and living quality in the regions of the country and to calculate aggregate social effect of FDI in Kazakhstan, having allocated the directions of its action on each of six factors in a regional section. The research did not reveal a negative impact of FDI on socio-economic development of the regions; moreover the aggregate social effect of FDI is positive for all regions of Kazakhstan. The authors believe that RPF Rating can become as the important tool of soundness of socio-economic policy in the area of development of public-private partnership in the regions of Kazakhstan, and also positive social effects of FDI growth in the long term — all of this will result in promoting a long-term positive impact on the welfare and living quality of the population of the republic.

  15. Depth of Field Effects for Interactive Direct Volume Rendering

    Schott, Mathias; Pascal Grosset, A.V.; Martin, Tobias; Pegoraro, Vincent; Smith, Sean T.; Hansen, Charles D.


    In this paper, a method for interactive direct volume rendering is proposed for computing depth of field effects, which previously were shown to aid observers in depth and size perception of synthetically generated images. The presented technique extends those benefits to volume rendering visualizations of 3D scalar fields from CT/MRI scanners or numerical simulations. It is based on incremental filtering and as such does not depend on any precomputation, thus allowing interactive explorations of volumetric data sets via on-the-fly editing of the shading model parameters or (multi-dimensional) transfer functions. © 2011 The Author(s).

  18. Direct effects of increasing carbon dioxide on vegetation

    Strain, B R; Cure, J D [eds.


    CO/sub 2/ is an essential environmental resource. It is required as a raw material of the orderly development of all green plants. As the availability of CO/sub 2/ increases, perhaps reaching two or three times the concentration prevailing in preindustrial times, plants and all other organisms dependent on them for food will be affected. Humans are releasing a gaseous fertilizer into the global atmosphere in quantities sufficient to affect all life. This volume considers the direct effects of global CO/sub 2/ fertilization on plants and thus on all other life. Separate abstracts have been prepared for individual papers. (ACR)

  19. Economic Analysis on Direct Use of Spent Pressurized Water Reactor Fuel in CANDU Reactors - I: DUPIC Fuel Fabrication Cost

    Choi, Hangbok; Ko, Won Il; Yang, Myung Seung


    A preliminary conceptual design of a Direct Use of spent Pressurized water reactor (PWR) fuel In Canada deuterium uranium (CANDU) reactors (DUPIC) fuel fabrication plant was studied, which annually converts spent PWR fuel of 400 tonnes heavy element (HE) into CANDU fuel. The capital and operating costs were estimated from the viewpoint of conceptual design. Assuming that the annual discount rate is 5% during the construction (5 yr) and operation period (40 yr) and contingency is 25% of the capital cost, the levelized unit cost (LUC) of DUPIC fuel fabrication was estimated to be 616 $/kg HE, which is mostly governed by annual operation and maintenance costs that correspond to 63% of LUC. Among the operation and maintenance cost components being considered, the waste disposal cost has the dominant effect on LUC (∼49%). From sensitivity analyses of production capacity, discount rate, and contingency, it was found that the production capacity of the plant is the major parameter that affects the LUC

  20. Direction of Effects in Multiple Linear Regression Models.

    Wiedermann, Wolfgang; von Eye, Alexander


    Previous studies analyzed asymmetric properties of the Pearson correlation coefficient using higher than second order moments. These asymmetric properties can be used to determine the direction of dependence in a linear regression setting (i.e., establish which of two variables is more likely to be on the outcome side) within the framework of cross-sectional observational data. Extant approaches are restricted to the bivariate regression case. The present contribution extends the direction of dependence methodology to a multiple linear regression setting by analyzing distributional properties of residuals of competing multiple regression models. It is shown that, under certain conditions, the third central moments of estimated regression residuals can be used to decide upon direction of effects. In addition, three different approaches for statistical inference are discussed: a combined D'Agostino normality test, a skewness difference test, and a bootstrap difference test. Type I error and power of the procedures are assessed using Monte Carlo simulations, and an empirical example is provided for illustrative purposes. In the discussion, issues concerning the quality of psychological data, possible extensions of the proposed methods to the fourth central moment of regression residuals, and potential applications are addressed.

  1. Economic impacts from energy efficiency programs - Variations in multiplier effects by program type and region. Volume 1

    Gardner, John; Skumatz, Lisa


    Research indicates that the value of omitted program effects - specifically non-energy benefits (NEBs) - represent a significant share of overall program impacts. One of the largest components of societal benefits is the direct and indirect economic and job creation effects stimulated by the investment in conservation on behalf of the program. The literature has indicated that the valuations assigned to this category of these categories can be large, but much of the literature overstates the impact of economic NEBs. We conducted extensive research to develop reliable and defensible estimates of these benefits categories. This study used input-output analysis to update the economic multipliers for NEBs in several ways. Net: Developed 'net' estimates of the multipliers (rather than 'gross' factors)Variations by Region: Estimated multipliers for multiple states and for the entire US; Variations by Program Type: Developed estimates based on different types or categories of programs (e.g weatherization vs. new construction vs. appliance programs, etc.), Variations in Baseline Assumptions: Different assumptions about where the expenditures are transferred 'from' for the net analysis (e.g. from 'generation', from a mixed market basket, etc.); and Variations over Time: Used data from multiple time periods to examine changes in the size of multipliers over time. We examined the results by state, by program type, and over time and found dramatic differences in the economic impacts by program type and territory under consideration. The results provide estimates of the economic impacts derived from the program; however, for communities or utilities with economic development goals, the results can be used to help select between program alternatives. The results are new, and the revised figures have been used to compute more reliable and tailored estimates of economic non-energy benefits that can be applied in regulatory tests

  2. Economic growth, energy consumption and CO2 emissions in OECD (Organization for Economic Co-operation and Development)'s transport sector: A fully modified bi-directional relationship approach

    Saboori, Behnaz; Sapri, Maimunah; Baba, Maizan bin


    This paper explores the bi-directional long-run relationship between energy consumption in the road transport sector with CO 2 emissions and economic growth in OECD countries. Using time series data from 1960 to 2008 and employing the Fully Modified Ordinary Least Squares cointegration approach, the paper shows positive significant long-run bi-directional relationship between CO 2 emissions and economic growth, road sector energy consumption and economic growth and CO 2 emissions and road sector energy consumption in all the OECD countries. To examine the response of each of the variables to shocks in the value of other variables, the generalized impulse response approach is employed. The response of CO 2 emissions to economic growth is initially positive in most cases but it is relatively shorter when compared to its initial response to the road transport sector energy consumption. Moreover, in most cases, the response of carbon emissions to the road transport sector energy consumption lasts longer than its response to economic growth. This implies that most of the CO 2 emissions from transport come from energy consumption, thus long-run policies related to the efficient use of energy and shifting to biofuel, renewable and nuclear energy can bring major benefits in mitigating GHG (Greenhouse Gas) emissions. - Highlights: • The relationship between GDP, energy and CO 2 in OECD's transport is investigated. • The Fully Modified Ordinary Least Squares cointegration approach was employed. • There is positive long-run bi-directional relationship between the variables. • The response of CO 2 to GDP is shorter than its response to the energy consumption

  3. Assessing Natural Direct and Indirect Effects Through Multiple Pathways

    . The approach is an extension of the natural effect models proposed by Lange et al. (Am J Epidemiol. 2012;176(3):190-195). By allowing the analysis of distinct multiple pathways, the suggested approach adds to the capabilities of modern mediation techniques. Furthermore, the approach can be implemented using......Within the fields of epidemiology, interventions research and social sciences researchers are often faced with the challenge of decomposing the effect of an exposure into different causal pathways working through defined mediator variables.

  4. Directed Motivational Currents: Using vision to create effective motivational pathways

    Christine Muir


    Full Text Available Vision, that is, the mental representation of the sensory experience of a future goal state (involving imagination and imagery, is currently at the forefront of motivational innovation, and in recent years it has been seen increasingly more often in the motivational tool kit of practicing language teachers. Theories such as Dörnyei’s L2 motivational self system have explored the power that creating effective visions can harness (see, e.g., Dörnyei & Kubanyiova, 2014 and when viewed in conjunction with other current research avenues, such as future time perspective and dynamic systems theory, vision offers exciting potential. A Directed Motivational Current is a new motivational construct that we suggest is capable of integrating many current theoretical strands with vision: It can be described as a motivational drive which energises long-term, sustained behaviour (such as language learning, and through placing vision and goals as critical central components within this construct, it offers real and practical motivational potential. In this conceptual paper, we first discuss current understandings of vision and of Directed Motivational Currents, and then analyse how they may be optimally integrated and employed to create effective motivational pathways in language learning environments.

  5. Multinational Corporations and Foreign Direct Investments in Romania. Effects on the Romanian Trade

    Catana Adina Mihaela


    Full Text Available This paper focuses on the study of transnational corporations and their business development through foreign direct investments made in other countries, mostly greenfield type countries. The objective of this paper is to determine the impact of these companies enlargement on the Romanian retail market, especially on the consumer goods market. Transnational companies have experienced a very dynamic economic growth, enjoying success at first in their country and then expanding to other countries. As independent players on the international market, multinational corporations are becoming more and more powerful every day. Most of these companies record annual sales of ten million dollars each. The most important aspect of business globalization is the interdependence between national economies. In this process, Foreign Direct Investments have an important role, given the fact that the internal resources are not enough to ensure the development and support of businesses hence the need to obtain external resources. Generally, FDI have a strong training effect both in the national and global economy, providing the replacement and modernization of techniques and technologies, increasing production and supply of goods, improving their quality and competitiveness, creating new jobs and growing the quality of life. Thus, each national economy is building its economic development strategy in which investments have a predominant role. Foreign Direct Investment is a major driver of globalization that characterizes the modern economy. Increasing of Foreign Direct Investment flows, accompanied by the increasing of the portfolio investments, highlights the major role played by transnational corporations, especially in developing economies and transition economies. The most important areas in which FDI was made in Romania are: financial intermediation and insurance, trade, construction and real estate, information technology and communication. The entering of

  14. [Effectiveness, population-level effects, and heath economics of measles and rubella vaccination].

    Wichmann, O; Ultsch, B


    Vaccination against measles and rubella has been included in national immunization programs worldwide for several decades. In this article, we present the evidence related to the effectiveness of measles and rubella vaccination based on published systematic reviews, and we describe the epidemiological and health economic effects of vaccination at a population level. Several observational studies demonstrate the high effectiveness (> 90 %) of both measles and rubella vaccination. The global measles mortality reduction and the dramatic decrease in rubella and measles incidences after introduction of routine immunization contribute to the very high quality of evidence. The countries of the Americas have proved that it is feasible to eliminate measles and rubella by strengthening infant immunization through routine vaccination services and by conducting supplemental immunization activities in other childhood age groups so as to close immunity gaps. An economic evaluation of measles and rubella vaccination specifically for the healthcare system in Germany does not exist. However, we conducted a systematic review and identified 11 health-economic studies from other industrialized countries and one for a hypothetical industrialized country. Results indicate that vaccination against measles and rubella had either a cost-effective or even a cost-saving potential, which could be assumed with some limitations also for the German setting. In conclusion, there is compelling evidence that the available vaccines are very effective and that measles and rubella elimination is feasible if adequate vaccination strategies are implemented. In Germany, catch-up vaccination programs are urgently needed for children, adolescents, and young adults specifically in the western federal states.

  15. Impacts of EU carbon emission trade directive on energy-intensive industries. Indicative micro-economic analyses

    Lund, Peter


    The cost impacts from the European emission trading system (ETS) on energy-intensive manufacturing industries have been investigated. The effects consist of direct costs associated to the CO 2 reduction requirements stated in the EU Directive, and of indirect costs of comparable magnitude that originate from a higher electricity price triggered by the ETS in the power sector. The total cost impacts remain below 2% of the production value for most industries within the ETS in the Kyoto period. In the post-Kyoto phase assuming a 30% CO 2 reduction, the total cost impact may raise up to 8% of production value in the heaviest industry sectors. In steel and cement industries the cost impacts are 3-4 fold compared to the least affected pulp and paper and oil refining. Electricity-intensive industries outside the ETS will also be affected, for example in aluminum and chlorine production the indirect cost impacts from ETS could come up to 10% of production value already in the Kyoto period. As industry sectors are affected differently by the ETS some correcting mechanisms may be worthwhile to consider in securing the operation of the most electricity-intensive sectors, e.g. balancing taxation schemes that may include as income source a levy on the wind-fall profits of the power sector due to ETS. A future improvement in ETS for industries within the scheme could be scaling of the emission reduction requirement so that the relative total emission reduction costs are at about the same level.

  17. Effect of External Economic-Field Cycle and Market Temperature on Stock-Price Hysteresis: Monte Carlo Simulation on the Ising Spin Model

    Punya Jaroenjittichai, Atchara; Laosiritaworn, Yongyut


    In this work, the stock-price versus economic-field hysteresis was investigated. The Ising spin Hamiltonian was utilized as the level of ‘disagreement’ in describing investors’ behaviour. The Ising spin directions were referred to an investor’s intention to perform his action on trading his stock. The periodic economic variation was also considered via the external economic-field in the Ising model. The stochastic Monte Carlo simulation was performed on Ising spins, where the steady-state excess demand and supply as well as the stock-price were extracted via the magnetization. From the results, the economic-field parameters and market temperature were found to have significant effect on the dynamic magnetization and stock-price behaviour. Specifically, the hysteresis changes from asymmetric to symmetric loops with increasing market temperature and economic-field strength. However, the hysteresis changes from symmetric to asymmetric loops with increasing the economic-field frequency, when either temperature or economic-field strength is large enough, and returns to symmetric shape at very high frequencies. This suggests competitive effects among field and temperature factors on the hysteresis characteristic, implying multi-dimensional complicated non-trivial relationship among inputs-outputs. As is seen, the results reported (over extensive range) can be used as basis/guideline for further analysis/quantifying how economic-field and market-temperature affect the stock-price distribution on the course of economic cycle.

  18. Helper effects on breeder allocations to direct care.

    Kushnick, Geoff


    Mothers receive childcare and productive assistance from allomaternal helpers in many societies. Although much effort has been aimed toward showing helper effects on maternal reproductive success, less has been directed toward highlighting the full range of potential effects on breeder behavior. I present a model of optimal maternal care with helpers, and tests of derived hypotheses with data collected among the Karo Batak-a group of Indonesian agriculturalists. To test the model's predictions I compared the effect of women receiving help from patrilateral versus matrilateral kin because those kin may provide help with different maternal responsibilities. The model predicts a decrease in maternal allocation to care that is substitutable with the helper contribution and the helper assists with that type of care; it predicts an increase in care that is nonsubstitutable with the helper contribution or substitutable care when the helper assists with other responsibilities. With the exception of one other, most models have failed to account for an increase. Analyses of time spent carrying children supported the model. With matrilateral helpers, women increased carrying; with patrilateral helpers, they decreased it. Time spent farmworking showed the opposite pattern, suggesting that matrilateral helpers effectively decrease costs, nudging optimal maternal care upward. Patterns of breastfeeding provided little support for the model. The results do, however, suggest potential proximate mechanisms by which helpers influence maternal reproductive success in cooperative breeding societies. Copyright © 2012 Wiley Periodicals, Inc.

  19. The effective field theory of dark matter direct detection

    Fitzpatrick, A. Liam; Haxton, Wick; Katz, Emanuel; Lubbers, Nicholas; Xu, Yiming


    We extend and explore the general non-relativistic effective theory of dark matter (DM) direct detection. We describe the basic non-relativistic building blocks of operators and discuss their symmetry properties, writing down all Galilean-invariant operators up to quadratic order in momentum transfer arising from exchange of particles of spin 1 or less. Any DM particle theory can be translated into the coefficients of an effective operator and any effective operator can be simply related to most general description of the nuclear response. We find several operators which lead to novel nuclear responses. These responses differ significantly from the standard minimal WIMP cases in their relative coupling strengths to various elements, changing how the results from different experiments should be compared against each other. Response functions are evaluated for common DM targets — F, Na, Ge, I, and Xe — using standard shell model techniques. We point out that each of the nuclear responses is familiar from past studies of semi-leptonic electroweak interactions, and thus potentially testable in weak interaction studies. We provide tables of the full set of required matrix elements at finite momentum transfer for a range of common elements, making a careful and fully model-independent analysis possible. Finally, we discuss embedding non-relativistic effective theory operators into UV models of dark matter.

  20. Main directions of providing of industrial enterprises effective development and conditions of their choice

    Y. V. Zhuravlev


    Full Text Available Difficulties in managing the effective development of an industrial enterprise is largely due to the lack of complex tools to measure it, which is aggravated by the lack of identification of the factors that affect the food industry enterprises. In the article, we investigated directions of providing of industrial enterprises effective development and determined conditions of their choice depending on organizational assets and enterprise’s added value dynamics. For every possible combination, we offered certain mechanism of effective development: internal – by means of enterprise’s self-potential activation, and external – by means of deep, moderate or shallow integration. Deep integration means full merger of the enterprise and is recommended in case of critical level of enterprise’s potential. Moderate integration is implemented by purchase of controlling block of shares and is carried out in case of critical or high enterprise’s potential combined with growth of added value. Shallow integration can be used in any combination of resources and added value and is implemented on a contractual basis without institutional and legal change. The concept of directions of providing of industrial enterprises development, that we worked out, is of applicable character and can be used by industrial enterprises regardless field and specific character of industry. Implementation of offered measures will provide industrial enterprises effective development, which will help to form organizational assets base of Russian economics, which is a powerful driver of modernization of Russian industrial enterprises and economics as a whole.

    Full Text Available This paper examined the long-run and short-run relationship between gasoline price and sectoral output in Nigeria for the period from 1980 to 2010. Six sectors (agriculture; manufacturing; building and construction; wholesale and retail; transportation and communication of the economy were examined. The long run regression estimate showed that gasoline price is a significant determinant output in all sectors examined with exception to the building and construction sector while the short run error correction estimate revealed that only output of the agriculture and the manufacturing sectors of the Nigerian economy is affect by gasoline price increase in the short run. The study recommended among others the need for the government to ensure adequate power supply in order to reduce the over reliance of economics sectors on gasoline as a prime source of power.

  2. Hybrid SOA-SQP algorithm for dynamic economic dispatch with valve-point effects

    Sivasubramani, S.; Swarup, K.S. [Department of Electrical Engineering, Indian Institute of Technology Madras, Chennai 600036 (India)


    This paper proposes a hybrid technique combining a new heuristic algorithm named seeker optimization algorithm (SOA) and sequential quadratic programming (SQP) method for solving dynamic economic dispatch problem with valve-point effects. The SOA is based on the concept of simulating the act of human searching, where the search direction is based on the empirical gradient (EG) by evaluating the response to the position changes and the step length is based on uncertainty reasoning by using a simple fuzzy rule. In this paper, SOA is used as a base level search, which can give a good direction to the optimal global region and SQP as a local search to fine tune the solution obtained from SOA. Thus SQP guides SOA to find optimal or near optimal solution in the complex search space. Two test systems i.e., 5 unit with losses and 10 unit without losses, have been taken to validate the efficiency of the proposed hybrid method. Simulation results clearly show that the proposed method outperforms the existing method in terms of solution quality. (author)

  3. The order of information processing alters economic gain-loss framing effects.

    Kwak, Youngbin; Huettel, Scott


    Adaptive decision making requires analysis of available information during the process of choice. In many decisions that information is presented visually - which means that variations in visual properties (e.g., salience, complexity) can potentially influence the process of choice. In the current study, we demonstrate that variation in the left-right positioning of risky and safe decision options can influence the canonical gain-loss framing effect. Two experiments were conducted using an economic framing task in which participants chose between gambles and certain outcomes. The first experiment demonstrated that the magnitude of the gain-loss framing effect was greater when the certain option signaling the current frame was presented on the left side of the visual display. Eye-tracking data during task performance showed a left-gaze bias for initial fixations, suggesting that the option presented on the left side was processed first. Combination of eye-tracking and choice data revealed that there was a significant effect of direction of first gaze (i.e. left vs. right) as well as an interaction between gaze direction and identity of the first fixated information (i.e. certain vs. gamble) regardless of frame. A second experiment presented the gamble and certain options in a random order, with a temporal delay between their presentations. We found that the magnitude of gain-loss framing was larger when the certain option was presented first, regardless of left and right positioning, only in individuals with lower risk-taking tendencies. The effect of presentation order on framing was not present in high risk-takers. These results suggest that the sequence of visual information processing as well as their left-right positioning can bias choices by changing the impact of the presented information during risky decision making.

  4. Spatial Spillover Effects of Transport Infrastructure in Chinese New Silk Road Economic Belt

    Jian Li


    Full Text Available Based on the inner-effect mechanism of transport infrastructure and regional economic growth, this paper builds a specialized spatial weight matrix by utilizing the panel data from 31 provinces in New Silk Road Economic Belt (NSREB and other areas from 2005 to 2014, and combines with the spatial panel model to analyze the spatial spillover effects of transport infrastructure. According to the analysis, the transport infrastructure plays an obvious lead role in regional economy growth alongside the NSREB, and the economic growth invigorates common development in surrounding regions. In addition, differences were observed among the different transport infrastructure with regard to their influences on regional economic development, as the highway transport affects regional economic growth to a larger degree than railway transport.

  5. Direct and indirect effects of neighborhood characteristics on the perpetration of dating violence across adolescence.

    Chang, Ling-Yin; Foshee, Vangie A; Reyes, Heathe Luz McNaughton; Ennett, Susan T; Halpern, Carolyn T


    Neighborhood context plays a role in the development of adolescent health risk behaviors, but few studies have investigated the influence of neighborhoods on the perpetration of dating violence. This longitudinal study examined the direct effects of risky neighborhood structural and physical characteristics on trajectories of the perpetration of dating violence, tested whether collective efficacy mediated these relationships, and determined if the effects varied by the sex of the adolescent. Adolescent data are from a multi-wave longitudinal study from grades 8 to 12; neighborhood data were collected from parents' interviews and U.S. Census data. Multilevel growth curve models were conducted with 3,218 students; the sample was 50% male, 41% White, 50% Black, and 9% other race/ethnicity. In models examining risky neighborhood variables one at a time, and controlling for potential individual-level confounders, the sex of the adolescent interacted with economic disadvantage, residential instability, and physical disorder; these risky neighborhood characteristics increased risk for girls' but not boys' perpetrating of dating violence. In full models with all of the risky neighborhood variables, the sex of the adolescent continued to interact with neighborhood economic disadvantage; living in economically disadvantaged neighborhoods increased girls' but not boys' risk for dating violence across all ages. No other risky neighborhood effects were found for boys or girls. Collective efficacy did not mediate the relationships between other neighborhood characteristics and the outcome. These findings suggest that dating violence prevention strategies for girls should consider the contexts in which they live rather than only targeting changes in their individual characteristics.

  6. The Effects of Unemployment on Economic Growth in Greece. An ARDL Bound Test Approach.

    Nikolaos Dritsakis


    Full Text Available The aim of this paper is to investigate the relationship between unemployment rate, economic growth and inflation rate in Greece, using annual data covering the period 1995-2015. The unit root tests results indicated that the variables have different integration order. Subsequently, the bounds testing (ARDL approach and ECM-ARDL model are applied in order to examine the long-run and the causal relationship between the variables. The empirical results of the study revealed, both in the short and long-run, that there is a unidirectional causal relationship between unemployment and economic growth with direction from unemployment to economic growth, as well as a unidirectional causality running from inflation to economic growth.

  8. Remote sensing of land surface temperature: The directional viewing effect

    Smith, J.A.; Schmugge, T.J.; Ballard, J.R. Jr.


    Land Surface Temperature (LST) is an important parameter in understanding global environmental change because it controls many of the underlying processes in the energy budget at the surface and heat and water transport between the surface and the atmosphere. The measurement of LST at a variety of spatial and temporal scales and extension to global coverage requires remote sensing means to achieve these goals. Land surface temperature and emissivity products are currently being derived from satellite and aircraft remote sensing data using a variety of techniques to correct for atmospheric effects. Implicit in the commonly employed approaches is the assumption of isotropy in directional thermal infrared exitance. The theoretical analyses indicate angular variations in apparent infrared temperature will typically yield land surface temperature errors ranging from 1 to 4 C unless corrective measures are applied

  9. Direct and Indirect Effects of Climate Change on Amphibian Populations

    Stephanie S. Gervasi


    Full Text Available As part of an overall decline in biodiversity, populations of many organisms are declining and species are being lost at unprecedented rates around the world. This includes many populations and species of amphibians. Although numerous factors are affecting amphibian populations, we show potential direct and indirect effects of climate change on amphibians at the individual, population and community level. Shifts in amphibian ranges are predicted. Changes in climate may affect survival, growth, reproduction and dispersal capabilities. Moreover, climate change can alter amphibian habitats including vegetation, soil, and hydrology. Climate change can influence food availability, predator-prey relationships and competitive interactions which can alter community structure. Climate change can also alter pathogen-host dynamics and greatly influence how diseases are manifested. Changes in climate can interact with other stressors such as UV-B radiation and contaminants. The interactions among all these factors are complex and are probably driving some amphibian population declines and extinctions.

  10. Did you say reference conditions? Ecological and socio-economic perspectives on the European Water Framework Directive

    Bouleau, Gabrielle; Pont, Didier


    Highlights: • Reference conditions refer to a stable state, ignoring non-linear and chaotic changes. • References were needed to set legally binding standards. • The DPSIR framework is based on a mitigation logic, which implies a stable reference. • Human activities do not equate pressures; Humans can create landscapes and ecosystems. • Setting goals for restoration requires a more adaptive management. - Abstract: Reference conditions are a key concept in the European Water Framework Directive (WFD). The WFD stipulates that the ecological status of a given water body shall be assessed by quantifying the deviation from a set of reference conditions that represent the stable state of an ecosystem in the absence of significant human disturbance. This concept is subject to criticism from several authors, particularly because underlying ecological concepts are weak and the distinction between natural variability and the effects of anthropogenic activities on ecosystem function will become increasingly artificial. In this paper, a sociologist and an aquatic ecologist examine the origin, successes and limits of the reference conditions concept and raise important questions about applying this concept in practice. We argue that this concept fitted specific needs from different institutions and stakeholders which promoted the WFD. Monitoring practices using this concept require some adaptations. Setting goals for restoration based on reference conditions is more problematic. A more adaptive management approach would be wiser

  11. Neuropsychological effects of cranial radiation: current knowledge and future directions

    Roman, Deborah D.; Sperduto, Paul W.


    Radiation is an invaluable therapeutic tool in the treatment of cancer, with well-established palliative and curative efficacy. As patient survival has improved, attention has focused on long-range treatment side effects. One such adverse effect, neuropsychological impairment, is incompletely understood. Much of the extant research has been directed at childhood leukemia survivors treated with low-dose whole-brain radiation. Less is known about the effects of high-dose focal or whole-brain radiation used in the treatment of brain lesions. This article reviews the scientific literature in this area, with greatest emphasis on methodologically rigorous studies. Research design considerations are discussed. Review findings suggest that low-dose whole-brain radiation (18 to 24 Gy) in children is associated with mild delayed IQ decline, with more substantial deficits occurring in children treated at a young age. A high incidence of learning disabilities and academic failure is observed in this population and may be caused by poor attention and memory rather than low intellectual level. Children who receive higher dose radiation for treatment of brain tumors experience more pronounced cognitive decline. At higher doses, whole-brain radiation, in particular, is linked to deleterious cognitive outcomes. Remarkably little is known about cognitive outcomes in irradiated adults. Preliminary findings indicate that certain cognitive functions, including memory, may be more vulnerable to decline than others. Suggestions for future research are proposed

  12. Direct effect of curcumin on porcine ovarian cell functions.

    Kádasi, Attila; Maruniaková, Nora; Štochmaľová, Aneta; Bauer, Miroslav; Grossmann, Roland; Harrath, Abdel Halim; Kolesárová, Adriana; Sirotkin, Alexander V


    Curcuma longa Linn (L.) is a plant widely used in cooking (in curry powder a.o.) and in folk medicine, but its action on reproductive processes and its possible mechanisms of action remain to be investigated. The objective of this study was to examine the direct effects of curcumin, the major Curcuma longa L. molecule, on basic ovarian cell functions such as proliferation, apoptosis, viability and steroidogenesis. Porcine ovarian granulosa cells were cultured with and without curcumin (at doses of 0, 1, 10 and 100μg/ml of medium). Markers of proliferation (accumulation of PCNA) and apoptosis (accumulation of bax) were analyzed by immunocytochemistry. The expression of mRNA for PCNA and bax was detected by RT-PCR. Cell viability was detected by trypan blue exclusion test. Release of steroid hormones (progesterone and testosterone) was measured by enzyme immunoassay (EIA). It was observed that addition of curcumin reduced ovarian cell proliferation (expression of both PCNA and its mRNA), promoted apoptosis (accumulation of both bax and its mRNA), reduced cell viability, and stimulated both progesterone and testosterone release. These observations demonstrate the direct suppressive effect of Curcuma longa L./curcumin on female gonads via multiple mechanisms of action - suppression of ovarian cell proliferation and viability, promotion of their apoptosis (at the level of mRNA transcription and subsequent accumulation of promoters of genes regulating these activities) and release of anti-proliferative and pro-apoptotic progesterone and androgen. The potential anti-gonadal action of curcumin should be taken into account by consumers of Curcuma longa L.-containing products. Copyright © 2017 Elsevier B.V. All rights reserved.

  13. Environmentally Sustainable Economic Growth

    Stelian Brad


    Full Text Available Economic growth and sustainable development are important issues for social prosperity. Sustainable development strives for moderate and responsible use within the economic activity of the limited resources of our planet, whereas economic growth does not limit the resource exploitation and energy, being mainly focused on productivity increase. From this perspective, both conceptual and operational contradictions occur between the two pillars of prosperity. This paper looks to these contradictions and proposes some streams of intervention such as economic growth and environmental sustainability to operate in harmony. A structured framework for innovative problem solving is considered in this respect. Results of this research show that it is possible to induce smart measures in the economic system for directing businesses towards new paradigms where economic growth is possible without negative effects on environmental sustainability.

  16. Organizing Effects of Testosterone and Economic Behavior: Not Just Risk Taking

    Brañas-Garza, Pablo; Rustichini, Aldo


    Recent literature emphasizes the role that testosterone, as well as markers indicating early exposure to T and its organizing effect on the brain (such as the ratio of second to fourth finger, ), have on performance in financial markets. These results may suggest that the main effect of T, either circulating or in fetal exposure, on economic behavior occurs through the increased willingness to take risks. However, these findings indicate that traders with a low digit ratio are not only more profitable, but more able to survive in the long run, thus the effect might consist of more than just lower risk aversion. In addition, recent literature suggests a positive correlation between abstract reasoning ability and higher willingness to take risks. To test the two hypotheses of testosterone on performance in financial activities (effect on risk attitude versus a complex effect involving risk attitude and reasoning ability), we gather data on the three variables in a sample of 188 ethnically homogeneous college students (Caucasians). We measure a digit ratio, abstract reasoning ability with the Raven Progressive Matrices task, and risk attitude with choice among lotteries. Low digit ratio in men is associated with higher risk taking and higher scores in abstract reasoning ability when a combined measure of risk aversion over different tasks is used. This explains both the higher performance and higher survival rate observed in traders, as well as the observed correlation between abstract reasoning ability and risk taking. We also analyze how much of the total effect of digit ratio on risk attitude is direct, and how much is mediated. Mediation analysis shows that a substantial part of the effect of T on attitude to risk is mediated by abstract reasoning ability. PMID:22242144

  17. The health and economic effects of counterfeit drugs.

    Blackstone, Erwin A; Fuhr, Joseph P; Pociask, Steve


    Counterfeit drugs comprise an increasing percentage of the US drug market and even a larger percentage in less developed countries. Counterfeit drugs involve both lifesaving and lifestyle drugs. To review the health and economic consequences of counterfeit drugs on the US public and on the healthcare system as a whole. This comprehensive review of the literature encompassed a search of MEDLINE/PubMed, Google Scholar, and ProQuest using the keywords "counterfeit drugs," "counterfeit medicines," "fake drugs," and "fake medicines." A search of the various FiercePharma daily newsletter series on the healthcare market was also conducted. In addition, the US Food and Drug Administration and the World Health Organization websites were reviewed for additional information. The issue of counterfeit drugs has been growing in importance in the United States, with the supply of these counterfeit drugs coming from all over the world. Innovation is important to economic growth and US competitiveness in the global marketplace, and intellectual property protections provide the ability for society to prosper from innovation. Especially important in terms of innovation in healthcare are the pharmaceutical and biopharmaceutical industries. In addition to taking income from consumers and drug companies, counterfeit drugs also pose health hazards to patients, including death. The case of bevacizumab (Avastin) is presented as one recent example. Internet pharmacies, which are often the source of counterfeit drugs, often falsely portray themselves as Canadian, to enhance their consumer acceptance. Adding to the problems are drug shortages, which facilitate access for counterfeits. A long and convoluted supply chain also facilitates counterfeits. In addition, the wholesale market involving numerous firms is a convenient target for counterfeit drugs. Trafficking in counterfeits can be extremely profitable; detection of counterfeits is difficult, and the penalties are modest. Counterfeit


    Artem Bilous


    Full Text Available The purpose of the paper is to explore the current state of the railway engineering industry in the world, the problems of its development prospects, especially the introduction of the modular process technology and economic impact of its introduction. Methodology. The research is based on statistical information from public sources, which is used to confirm the veracity of the thesis put forward about the feasibility of further implementation of the principle of modularity in the railway engineering sector. Data was also obtained from the websites of manufacturers of railway equipment. Also, in the study of the issue, analytical articles on the economic development of the sector of railway engineering in the world were used. Results of the research showed that today, in transport engineering industry, in particular – in the railway engineering, there is a problem of inefficient implementation and use of technological developments, which are used in the manufacture of railway rolling stock. Many technical solutions are duplicated, leading to more time and financial costs. At the same time, there is no free access to information about existing technical solutions, which significantly slows down the development of rail transport. One of the main solutions to the problem is the use of modular technology in the design and manufacture of rolling stock. Leading global manufacturers have already begun to use the modules in the production of their rolling stock, but the technology is not yet sufficiently developed and finds its realization only in reducing the costs of production of rolling stock by specific manufacturers. The full benefits of the new technology have not yet been obtained by producers and operators. Thus, there is a considerable margin for the implementation of modular technology in the production of railway vehicles, which will result in further reducing both production costs and the costs of maintenance, operation and repair of

  19. Study on Spatial Spillover Effects of Logistics Industry Development for Economic Growth in the Yangtze River Delta City Cluster Based on Spatial Durbin Model.

    Xu, Xinxing; Wang, Yuhong


    The overall entropy method is used to evaluate the development level of the logistics industry in the city based on a mechanism analysis of the spillover effect of the development of the logistics industry on economic growth, according to the panel data of 26 cities in the Yangtze River delta. On this basis, the paper uses the spatial durbin model to study the direct impact of the development of the logistics industry on economic growth and the spatial spillover effect. The results show that the direct impact coefficient of the development of the logistics industry in the Yangtze River Delta urban agglomeration on local economic growth is 0.092, and the significant spatial spillover effect on the economic growth in the surrounding area is 0.197. Compared with the labor force input, capital investment and the degree of opening to the world, and government functions, the logistics industry's direct impact coefficient is the largest, other than capital investment; the coefficient of the spillover effect is higher than other control variables, making it a "strong engine" of the Yangtze River Delta urban agglomeration economic growth.

  1. Leverage effect, economic policy uncertainty and realized volatility with regime switching

    Duan, Yinying; Chen, Wang; Zeng, Qing; Liu, Zhicao


    In this study, we first investigate the impacts of leverage effect and economic policy uncertainty (EPU) on future volatility in the framework of regime switching. Out-of-sample results show that the HAR-RV including the leverage effect and economic policy uncertainty with regimes can achieve higher forecast accuracy than RV-type and GARCH-class models. Our robustness results further imply that these factors in the framework of regime switching can substantially improve the HAR-RV's forecast performance.

  2. Compare the Effect of Health on Iranian Economic Growth and Vision Basin Countries

    A AlaviRad


    Conclusion: Results show that spending money on health and rewardingly achieving health and additional desirability can be effective on economic growth increase. Health condition in Iran has also positive effect on economic growth, but in comparison, Iran is among thecountries that gets lower results by spending more. This can be considered as motivation for Policy makers to pay more attention to health condition in Sanad-e-CheshmAndaz countries. However, there are some questions remaining about appropriating resources as well as efficiency.

  3. Effect of socio-economic status on sleep.

    Seo, Won Hee; Kwon, Jung Hyun; Eun, So-Hee; Kim, Gunha; Han, Kyungdo; Choi, Byung Min


    Sufficient sleep is an important factor in physical and mental health. Sleep duration can be affected by socio-economic status (SES). This study aimed to examine the association between sleep duration and SES in Korean adolescents. This study was conducted with 1608 adolescents aged 12-18 years, based on data from the 2010 to 2012 Korean National Health and Nutrition Examination Survey (KNHANES). Sleep duration was self-reported in hours and three SES indicators were used: household income, basic livelihood security programmes and type of health insurance. Confounding factors in this study were age, mental health and physical activity. Participants' average age was 15.6 ± 0.05 years and average sleep duration was 7.04 ± 0.05 h. There was a strong association between sleep duration and household income (P sleep duration was significantly associated with age, body mass index (P sleep and long sleep (>9 h/night). We found similar results in both genders, that is, that the highest income group had shorter sleep duration than the lowest income group. This study shows that the SES, particularly household income, is an important factor in short sleep duration in Korean adolescents. Our findings suggest that, in future investigations of the adolescent's sleep problem, attention should be paid to household income. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

  4. A behavioral economics perspective on the overjustification effect: Crowding-in and crowding-out of intrinsic motivation.

    Weibel, Antoinette; Wiemann, Meike; Osterloh, Margit


    In the last two decades, economic motivation research has undergone a paradigm shift when it comes to the effect of incentive schemes on individual performance and motivation. Inspired by self-determination theory, a new branch in economics evolved called behavioral economics. Especially by evidencing the negative effect of “pay-for-performance” on intrinsic motivation, called the “crowding-out” or “overjustification” effect, it challenges the economic paradigm of the relative price-effect an...

    An economic study was conducted alongside a clinical trial at three sites in Pakistan to establish the costs and effectiveness of different strategies for implementing directly observed treatment (DOT) for tuberculosis. Patients were randomly allocated to one of three arms: DOTS with direct observation by health workers (at health centres or by community health workers); DOTS with direct observation by family members; and DOTS without direct observation. The clinical trial found no statistically significant difference in cure rate for the different arms. The economic study collected data on the full range of health service costs and patient costs of the different treatment arms. Data were also disaggregated by gender, rural and urban patients, by treatment site and by economic categories, to investigate the costs of the different strategies, their cost-effectiveness and the impact that they might have on patient compliance with treatment. The study found that direct observation by health centre-based health workers was the least cost-effective of the strategies tested (US dollars 310 per case cured). This is an interesting result, as this is the model recommended by the World Health Organization and International Union against Tuberculosis and Lung Disease. Attending health centres daily during the first 2 months generated high patient costs (direct and in terms of time lost), yet cure rates for this group fell below those of the non-observed group (58%, compared with 62%). One factor suggested by this study is that the high costs of attending may be deterring patients, and in particular, economically active patients who have most to lose from the time taken by direct observation. Without stronger evidence of benefits, it is hard to justify the costs to health services and patients that this type of direct observation imposes. The self-administered group came out as most cost-effective (164 dollars per case cured). The community health worker sub-group achieved the

  6. Polyphyletic migration operator and orthogonal learning aided biogeography-based optimization for dynamic economic dispatch with valve-point effects

    Xiong, Guojiang; Li, Yinhong; Chen, Jinfu; Shi, Dongyuan; Duan, Xianzhong


    Highlights: • New method for dynamic economic dispatch problem using POLBBO. • Considering valve-point effects, ramp rate limits, transmission network losses. • POLBBO is able to balance the global exploration and the local exploitation. • An effective simultaneous constraints handling technique is proposed. • The achieved results by POLBBO are better than those reported in other literatures. - Abstract: Shortage of energy resources, rising power generation cost, and increasing electric energy demand make the dynamic economic dispatch (DED) increasingly necessary in today’s competitive electricity market. In this paper, an enhanced biogeography-based optimization (BBO) referred to as POLBBO is proposed to solve the DED problem with valve-point effects. BBO is a relatively new powerful population-based meta-heuristic algorithm inspired by biogeography and has been extensively applied to many scientific and engineering problems. However, its direct-copying-based migration and random mutation operators make BBO possess good local exploitation ability but lack enough global exploration ability. To remedy the defect, on one hand, an efficient operator named polyphyletic migration operator is proposed to enhance the search ability of POLBBO. This operator can not only generate new features from more promising areas in the search space, but also effectively increase the population diversity. On the other hand, an orthogonal learning (OL) strategy based on orthogonal experimental design is presented. The OL strategy can quickly discover useful information from the search experiences and effectively utilize the information to construct a more promising solution, and thereby provide a systematic and elaborate reasoning method to guide the search directions of POLBBO. In addition, an effective simultaneous constraints handling technique without penalty factor settings is developed to handle various complicated constraints of the DED problem. Finally, four test

  7. Improving models of democracy: the example of lagged effects of economic development, education, and gender equality.

    Balaev, Mikhail


    The author examines how time delayed effects of economic development, education, and gender equality influence political democracy. Literature review shows inadequate understanding of lagged effects, which raises methodological and theoretical issues with the current quantitative studies of democracy. Using country-years as a unit of analysis, the author estimates a series of OLS PCSE models for each predictor with a systematic analysis of the distributions of the lagged effects. The second set of multiple OLS PCSE regressions are estimated including all three independent variables. The results show that economic development, education, and gender have three unique trajectories of the time-delayed effects: Economic development has long-term effects, education produces continuous effects regardless of the timing, and gender equality has the most prominent immediate and short term effects. The results call for the reassessment of model specifications and theoretical setups in the quantitative studies of democracy. Copyright © 2014 Elsevier Inc. All rights reserved.

  8. Mechanisms and Effects of Transcranial Direct Current Stimulation

    Giordano, James; Bikson, Marom; Kappenman, Emily S.; Clark, Vincent P.; Coslett, H. Branch; Hamblin, Michael R.; Hamilton, Roy; Jankord, Ryan; Kozumbo, Walter J.; McKinley, R. Andrew; Nitsche, Michael A.; Reilly, J. Patrick; Richardson, Jessica; Wurzman, Rachel


    The US Air Force Office of Scientific Research convened a meeting of researchers in the fields of neuroscience, psychology, engineering, and medicine to discuss most pressing issues facing ongoing research in the field of transcranial direct current stimulation (tDCS) and related techniques. In this study, we present opinions prepared by participants of the meeting, focusing on the most promising areas of research, immediate and future goals for the field, and the potential for hormesis theory to inform tDCS research. Scientific, medical, and ethical considerations support the ongoing testing of tDCS in healthy and clinical populations, provided best protocols are used to maximize safety. Notwithstanding the need for ongoing research, promising applications include enhancing vigilance/attention in healthy volunteers, which can accelerate training and support learning. Commonly, tDCS is used as an adjunct to training/rehabilitation tasks with the goal of leftward shift in the learning/treatment effect curves. Although trials are encouraging, elucidating the basic mechanisms of tDCS will accelerate validation and adoption. To this end, biomarkers (eg, clinical neuroimaging and findings from animal models) can support hypotheses linking neurobiological mechanisms and behavioral effects. Dosage can be optimized using computational models of current flow and understanding dose–response. Both biomarkers and dosimetry should guide individualized interventions with the goal of reducing variability. Insights from other applied energy domains, including ionizing radiation, transcranial magnetic stimulation, and low-level laser (light) therapy, can be prudently leveraged. PMID:28210202

  9. Direct observation of the spin-dependent Peltier effect.

    Flipse, J; Bakker, F L; Slachter, A; Dejene, F K; van Wees, B J


    The Peltier coefficient describes the amount of heat that is carried by an electrical current when it passes through a material. When two materials with different Peltier coefficients are placed in contact with one another, the Peltier effect causes a net flow of heat either towards or away from the interface between them. Spintronics describes the transport of electric charge and spin angular momentum by separate spin-up and spin-down channels in a device. The observation that spin-up and spin-down charge transport channels are able to transport heat independently of each other has raised the possibility that spin currents could be used to heat or cool the interface between materials with different spin-dependent Peltier coefficients. Here, we report the direct observation of the heating and cooling of such an interface by a spin current. We demonstrate this spin-dependent Peltier effect in a spin-valve pillar structure that consists of two ferromagnetic layers separated by a non-ferromagnetic metal. Using a three-dimensional finite-element model, we extract spin-dependent Peltier coefficients in the range -0.9 to -1.3 mV for permalloy. The magnetic control of heat flow could prove useful for the cooling of nanoscale electronic components or devices.

    To examine the clinical effectiveness, tolerability and cost-effectiveness of gabapentin (GBP), lamotrigine (LTG), levetiracetam (LEV), oxcarbazepine (OXC), tiagabine (TGB), topiramate (TPM) and vigabatrin (VGB) for epilepsy in adults. Electronic databases. Internet resources. Pharmaceutical company submissions. Selected studies were screened and quality assessed. Separate analyses assessed clinical effectiveness, serious, rare and long-term adverse events and cost-effectiveness. An integrated economic analysis incorporating information on costs and effects of newer and older antiepileptic drugs (AEDs) was performed to give direct comparisons of long-term costs and benefits. A total of 212 studies were included in the review. All included systematic reviews were Cochrane reviews and of good quality. The quality of randomised controlled trials (RCTs) was variable. Assessment was hampered by poor reporting of methods of randomisation, allocation concealment and blinding. Few of the non-randomised studies were of good quality. The main weakness of the economic evaluations was inappropriate use of the cost-minimisation design. The included systematic reviews reported that newer AEDs were effective as adjunctive therapy compared to placebo. For newer versus older drugs, data were available for all three monotherapy AEDs, although data for OXC and TPM were limited. There was limited, poor-quality evidence of a significant improvement in cognitive function with LTG and OXC compared with older AEDs. However, there were no consistent statistically significant differences in other clinical outcomes, including proportion of seizure-free patients. No studies assessed effectiveness of AEDs in people with intellectual disabilities or in pregnant women. There was very little evidence to assess the effectiveness of AEDs in the elderly; no significant differences were found between LTG and carbamazepine monotherapy. Sixty-seven RCTs compared adjunctive therapy with placebo, older

  11. Can Economic Deprivation Protect Health? Paradoxical Multilevel Effects of Poverty on Hispanic Children’s Wheezing

    Collins, Timothy W.; Kim, Young-an; Grineski, Sara E.; Clark-Reyna, Stephanie


    Prior research suggests that economic deprivation has a generally negative influence on residents’ health. We employ hierarchical logistic regression modeling to test if economic deprivation presents respiratory health risks or benefits to Hispanic children living in the City of El Paso (Texas, USA) at neighborhood- and individual-levels, and whether individual-level health effects of economic deprivation vary based on neighborhood-level economic deprivation. Data come from the US Census Bureau and a population-based survey of El Paso schoolchildren. The dependent variable is children’s current wheezing, an established respiratory morbidity measure, which is appropriate for use with economically-deprived children with an increased likelihood of not receiving a doctor’s asthma diagnosis. Results reveal that economic deprivation (measured based on poverty status) at both neighborhood- and individual-levels is associated with reduced odds of wheezing for Hispanic children. A sensitivity analysis revealed similar significant effects of individual- and neighborhood-level poverty on the odds of doctor-diagnosed asthma. Neighborhood-level poverty did not significantly modify the observed association between individual-level poverty and Hispanic children’s wheezing; however, greater neighborhood poverty tends to be more protective for poor (as opposed to non-poor) Hispanic children. These findings support a novel, multilevel understanding of seemingly paradoxical effects of economic deprivation on Hispanic health. PMID:25101769

  13. Social murder: the long-term effects of conservative economic policy.

    Chernomas, Robert; Hudson, Ian


    In this article, the authors take inspiration from Engels's 1845 account of the social murder committed by British capitalists to assess the contemporary impact of conservative economic policy, which they define as policies designed to maximize the accumulation of profit while socializing the associated risks and costs. Conservative economists argue that if their policy prescription is followed, it will produce broad-based economic benefits including more rapid growth, higher incomes, less illness, and, even, more democracy. The authors contrast the myth of conservative economic policy with the reality. What conservative economic policy has actually accomplished is a redistribution of wealth and power away from the vast majority of the population to firms and their owners. The effects of these policies on citizens and workers have been socially determined economic instability, unemployment, poverty, inequality, dangerous products, and infectious and chronic disease.

  14. Effect of Heifer Frame Score on Growth, Fertility, and Economics

    Şentürklü, S.; Landblom, D. G.; Perry, G. A.; Petry, T.


    A non-traditional forage-based protocol was employed to evaluate replacement heifer growth, fertility, and economics between small frame (SF, 3.50; n = 50) and large frame (LF, 5.56; n = 50) heifers using three increasing gain growth phases. Preceding an 85 d growing-breeding period (Phase 3; P3) the heifers were managed as a common group for Phases 1 and 2 (P1 and P2). During P1, heifers grazed common fields of unharvested corn and corn residue (total digestible nutrients [TDN] 56%) with supplemental hay. For P2, heifers grazed early spring crested wheatgrass pasture (CWG; TDN 62%) that was followed by the final P3 drylot growing and breeding period (TDN 68%). Small frame heifers were lighter at the end of P1 in May and at the start of P3 breeding in August (p = 0.0002). Percent of mature body weight (BW) at the end of P1 (209 d) was 48.7% and 46.8%, respectively, for the SF and LF heifers and the percent pubertal was lower for SF than for LF heifers (18.0% vs 40.0%; p = 0.02). At breeding initiation (P3), the percentage of mature BW was 57.8 and 57.2 and the percentage pubertal was 90.0 and 96.0 (p = 0.07) for the SF and LF heifers, respectively; a 5-fold increase for SF heifers. Breeding cycle pregnancy on days 21, 42, and 63, and total percent pregnant did not differ (p>0.10). In drylot, SF heifer dry matter intake (DMI) was 20.1% less (p = 0.001) and feed cost/d was 20.3% lower (p = 0.001), but feed cost/kg of gain did not differ between SF and LF heifers (p = 0.41). Economically important live animal measurements for muscling were measured in May and at the end of the study in October. SF heifers had greater L. dorsi muscle area per unit of BW than LF heifers (p = 0.03). Small frame heifer value was lower at weaning (p = 0.005) and the non-pregnant ending heifer value was lower for SF heifers than for the LF heifers (p = 0.005). However, the total development cost was lower for SF heifers (p = 0.001) and the net cost per pregnant heifer, after accounting for

  16. The modelling of direct chemical kinetic effects in turbulent flames

    Lindstet, R.P. [Imperial College of Science, Technology and Medicine, London (United Kingdom). Dept. of Mechanical Engineering


    Combustion chemistry-related effects have traditionally been of secondary importance in the design of gas turbine combustors. However, the need to deal with issues such as flame stability, relight and pollutant emissions has served to bring chemical kinetics and the coupling of finite rate chemistry with turbulent flow fields to the centre of combustor design. Indeed, improved cycle efficiency and more stringent environmental legislation, as defined by the ICAO, are current key motivators in combustor design. Furthermore, lean premixed prevaporized (LPP) combustion systems, increasingly used for power generation, often operate close to the lean blow-off limit and are prone to extinction/reignition type phenomena. Thus, current key design issues require that direct chemical kinetic effects be accounted for accurately in any simulation procedure. The transported probability density function (PDF) approach uniquely offers the potential of facilitating the accurate modelling of such effects. The present paper thus assesses the ability of this technique to model kinetically controlled phenomena, such as carbon monoxide emissions and flame blow-off, through the application of a transported PDF method closed at the joint scalar level. The closure for the velocity field is at the second moment level, and a key feature of the present work is the use of comprehensive chemical kinetic mechanisms. The latter are derived from recent work by Lindstedt and co-workers that has resulted in a compact 141 reactions and 28 species mechanism for LNG combustion. The systematically reduced form used here features 14 independent C/H/O scalars, with the remaining species incorporated via steady state approximations. Computations have been performed for hydrogen/carbon dioxide and methane flames. The former (high Reynolds number) flames permit an assessment of the modelling of flame blow-off, and the methane flame has been selected to obtain an indication of the influence of differential

    Full Text Available It is assumed that the biomass is one of the basic non-conventional energy sources in Poland. Among the cereals cultivated in Poland grain oats appears to be the most useful to be used for energy purposes, as it is less important for consumption and feed, cultivation technology is well known to farmers and the energy value of approx. 17 MJ kg-1. The aim of the study was to evaluate the cost-effectiveness and environmental impact of the use of oats for direct combustion, as compared with conventional fuel ie. the fine coal. In the economic part a simplified calculation of the cost of oats production was carried out and next it was compared with the cost of the purchase of oats and fine coal. The impact of oats to the environment was also analyzed and the natural emission of gases and dust during grain combustion. The results were compared with the impact on the environment taking into account the production of fine coal mining, transport and combustion of the fuel. It was found that the use of oats for energy purposes is cost-effective, especially if the grain is produced on their own farm using low-cost technology. It also provides environmental benefits, as it allows to reduce the consumption of fossil fuels and reduce the emission of noxious gases and dust into the atmosphere

  18. Selected spatial effects of the global financial and economic crisis in Ljubljana, Slovenia

    Simon Kušar


    Full Text Available In 2007, the United States witnessed a financial crisis that gradually developed into one of the most serious global financial and economic recessions in the history of (postmodern society. Its effects are numerous. This article studies one of its spatial effects; that is, newly built (after 2005 residential and office buildings that are either unfinished or already built but not fully occupied. In Ljubljana in November 2011, there were ninety-seven locations with unoccupied or partly occupied residential houses and office buildings or groups of houses and office buildings together with abandoned or active construction sites. The majority of the structures studied were predominately represented by several blocks of flats and groups of dwellings. The others are office buildings or buildings and complexes with distinctively mixed residential-business functions. There are more than 1,500 empty flats and almost 75,000 m² of office area in the buildings surveyed. Spatial analysis showed that the structures surveyed are relatively scattered throughout Ljubljana. However, there were some clusters of buildings, especially in areas with the best accessibility. This article analyses the causes of this phenomenon, which is creating a new morphological element in Ljubljana. The article concludes by stating possible directions for future research.

  19. A methodological framework for assessing agreement between cost-effectiveness outcomes estimated using alternative sources of data on treatment costs and effects for trial-based economic evaluations.

    Achana, Felix; Petrou, Stavros; Khan, Kamran; Gaye, Amadou; Modi, Neena


    A new methodological framework for assessing agreement between cost-effectiveness endpoints generated using alternative sources of data on treatment costs and effects for trial-based economic evaluations is proposed. The framework can be used to validate cost-effectiveness endpoints generated from routine data sources when comparable data is available directly from trial case report forms or from another source. We illustrate application of the framework using data from a recent trial-based economic evaluation of the probiotic Bifidobacterium breve strain BBG administered to babies less than 31 weeks of gestation. Cost-effectiveness endpoints are compared using two sources of information; trial case report forms and data extracted from the National Neonatal Research Database (NNRD), a clinical database created through collaborative efforts of UK neonatal services. Focusing on mean incremental net benefits at £30,000 per episode of sepsis averted, the study revealed no evidence of discrepancy between the data sources (two-sided p values >0.4), low probability estimates of miscoverage (ranging from 0.039 to 0.060) and concordance correlation coefficients greater than 0.86. We conclude that the NNRD could potentially serve as a reliable source of data for future trial-based economic evaluations of neonatal interventions. We also discuss the potential implications of increasing opportunity to utilize routinely available data for the conduct of trial-based economic evaluations.

  20. The effect of economic downturn on the volume of surgical procedures: A systematic review.

    Fujihara, Nasa; Lark, Meghan E; Fujihara, Yuki; Chung, Kevin C


    Economic downturn can have a wide range of effects on medicine at both individual and national levels. We aim to describe these effects in relation to surgical volume to guide future planning for physician specialization, patient expectations in the face of economic crises, or estimating healthcare expenditure. We hypothesized that because of high out-of-pocket costs, cosmetic procedure volumes would be most affected by economic decline. A systematic review was conducted using MEDLINE, Embase, and ABI/INFORMS. The main search terms were "economic recession" and "surgical procedures, operative". Studies were included if surgical volumes were measured and economic indicators were used as predictors of economic conditions. Twelve studies were included, and the most common subject was cosmetic (n = 5), followed by orthopedic (n = 2) and cardiac surgeries (n = 2). The majority of studies found that in periods of economic downturn, surgical volume decreased. Among the eight studies using Pearson's correlation analysis, there were no significant differences between cosmetic procedures and other elective procedures, indicating that cosmetic procedures may display trends similar to those of non-cosmetic elective procedures in periods of economic downturn. Surgical volume generally decreased when economic indicators declined, observed for both elective and non-elective surgery fields. However, a few specific procedure volumes such as vasectomy and caesarean section for male babies increased during the economic downturn. Knowledge of these trends can be useful for future surgical planning and distribution of healthcare resources. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd.

    Full Text Available This article studies the controversial relationship between human capital and growth through different channels using a cross-country panel approach applied for 104 countries, including 79 developing countries and 25 developed countries (OECD during 1980-2011. The analysis yields important insights into the relationship between human capital and growth. Firstly, we find a significant relationship between high levels of human capital and technology adoption Secondly, considering the levels of human capital directly as a innovation component in the productivity function shows that there is a non-linear relationship between this factor and growth. The results provide a new understanding of this relationship and to some extent contradict some earlier studies.

    Immediately prior to the passage of the 1962 Food and Drug Administration Amendments, there were a number of drugs recalled from markets worldwide. Announcements about the dangerous side effects of these drugs were associated with lower-share prices for their manufacturers and the industry as a whole. We perform several analyses to sort out alternative explanations for the observed declines. We find that dangerous drug announcements had no effect on the sales of other drugs and didn't affect ...

  5. The EU's Agenda 2000 reform for the agricultural sector. Environmental and economic effects in Denmark

    Wier, Mette; Andersen, Johnny M.; Jensen, Joergen D.; Jensen, Thomas C.


    The Agenda 2000 reform, agreed on by the EU government leaders in the spring of 1999, implies considerable changes in EU agricultural policy. The reform involves both reductions in price support and compensations in the form of hectare and animal support. The Agenda 2000 reform may have considerable environmental and economic effects, and in this article we assess these effects. Within an integrated model system, we calculate environmental effects (changes in nitrogen loading in the terrestrial environment and the Danish marine waters, changes in oxygen concentrations in the inner Danish marine waters, and changes in emissions of the greenhouse gases (methane and nitrous oxide)), as well as economic effects (effects on private consumption, GDP, the balance of payments, and employment). The results indicate that the Agenda 2000 reform has significant economic costs but almost no effects on the environment - either positive or negative

  6. Health economic modeling of the potential cost saving effects of Neurally Adjusted Ventilator Assist.

    Hjelmgren, Jonas; Bruce Wirta, Sara; Huetson, Pernilla; Myrén, Karl-Johan; Göthberg, Sylvia


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

  7. The Economics of Colon Cancer.

    Orangio, Guy R


    The economic burden of cancer on the national health expenditure is billions of dollars. The economic cost is measured on direct and indirect medical costs, which vary depending on stage at diagnosis, patient age, type of medical services, and site of service. Costs vary by region, physician behavior, and patient preferences. When analyzing the economic burden of survivors of colon cancer, we cannot forget the societal burden. Post-acute care and readmissions are major economic burdens. People with colon cancer have to be followed for their lifetime. Economic models are being studied to give cost-effective solutions to this problem. Copyright © 2017 Elsevier Inc. All rights reserved.

  8. Economic and environmental effects of the FQD on crude oil production from tar sands

    Kampman, B.; De Buck, A.; Afman, M. [CE Delft, Delft (Netherlands); Van den Berg, J.; Otten, G.J. [Carbon Matters, Den Haag (Netherlands)


    The production of unconventional crudes in Canada and Venezuela and exports of these crudes to the EU are investigated. In addition the potential economic and environmental impact of the proposed EU FQD measures (Fuel Quality Directive) on the production of crudes from tar sands and on new tar sand exploration projects are examined. CE Delft has analysed the impact by using a dedicated cost model. For existing projects, the model determines the effect on the basis of marginal production costs. For planned projects the model used the net present value (NPV) of proposed investments. The impacts were determined for a range of crude oil prices and FQD price effects. Combined, for existing and new projects together, the maximum effect would be at a price level at 60 USD/bbl, with savings of up to 19 Mt CO2/y at an FQD price differential of 3 euro/bbl. This overall effect would be substantial and come on top of the total emission reduction effect of the FQD of 60 Mt CO2/y, which will be achieved mostly by the blending of low-carbon fuels and reduced flaring and venting. As part of the reduction of transport greenhouse gas (GHG) emissions, the revised FQD obliges fuel suppliers to reduce these emissions by 6% by 2020 on a well-to-wheel basis. The EU is currently developing a methodology to differentiate fossil fuels on the basis of feedstock and GHG emissions. In the proposal, diesel produced from tar sands, has been given a default emission value of 108.5 gCO2 eq/MJ, while diesel from conventional crude was set at 89.1 gCO2 eq/MJ. The Commission's proposal is currently undergoing an impact assessment and is expected to be resubmitted to the Council later this year (2013)

Results have validated what the literature says, namely that FDI exerts a positive influence on economic growth in the FDI receiving countries.

  10. The Effect of Corruption on Foreign Direct Investment: A Panel Data Study

    EPAPHRA, Manamba; MASSAWE, John


    Abstract. Foreign direct investment (FDI) has become an important factor of development in low income countries. At the same time, corruption continues to be one of the greatest obstacles to economic and social development in these countries. However, in East Africa, the study of the nature of corruption as well as its relationship with FDI is scanty in socio-economic literature. In addition, the existing literature provides controversial results. Motivated by these issues, this paper examine...

  11. Pahoa geothermal industrial park. Engineering and economic analysis for direct applications of geothermal energy in an industrial park at Pahoa, Hawaii

    Moreau, J.W.


    This engineering and economic study evaluated the potential for developing a geothermal industrial park in the Puna District near Pahoa on the Island of Hawaii. Direct heat industrial applications were analyzed from a marketing, engineering, economic, environmental, and sociological standpoint to determine the most viable industries for the park. An extensive literature search produced 31 existing processes currently using geothermal heat. An additional list was compiled indicating industrial processes that require heat that could be provided by geothermal energy. From this information, 17 possible processes were selected for consideration. Careful scrutiny and analysis of these 17 processes revealed three that justified detailed economic workups. The three processes chosen for detailed analysis were: an ethanol plant using bagasse and wood as feedstock; a cattle feed mill using sugar cane leaf trash as feedstock; and a papaya processing facility providing both fresh and processed fruit. In addition, a research facility to assess and develop other processes was treated as a concept. Consideration was given to the impediments to development, the engineering process requirements and the governmental support for each process. The study describes the geothermal well site chosen, the pipeline to transmit the hydrothermal fluid, and the infrastructure required for the industrial park. A conceptual development plan for the ethanol plant, the feedmill and the papaya processing facility was prepared. The study concluded that a direct heat industrial park in Pahoa, Hawaii, involves considerable risks.

  12. Gelişmekte Olan Ülkelerde Doğrudan Yabancı Yatırımlar ve Ekonomik Entegrasyon:ASEAN ve MERCOSUR Örneği(Foreign Direct Investments and Economic Integration in Developing Countries: The Cases of ASEAN and MERCOSUR

    Hamza ÇEŞTEPE


    Full Text Available It is known that membership in regional economic integrations has an important effect in determining foreign direct investments (FDI. In this study, the effect of regional economic integration on FDI was empirically analysed for ASEAN and MERCOSUR established by developing countries. The model constructed in this paper included a dummy variable for regional economic integrations for the 1980-2007 period and fixed effects panel data method is used. According to estimated results, membership to regional economic integrations together with other factors has increased FDI flows. With the current increasing regionalization trend, this study suggests that in order to attract higher amounts of FDI, developing countries should emphasize regional economic integration, or at least they should make trade agreements.

  14. Causes and Effects in Macroeconomics: 2011 Nobel Prize Lecture in Economic Sciences

    Shlair Abdulkhaleq Al-Zanganee


    Full Text Available Noble Laureates Thomas Sargent and Christopher Sims have been granted the 2011 Noble Prize in economic sciences in appreciation of their empirical research on causes and effects in macroeconomics. The controversy on causality in macroeconomics was discussed in both of Sargent’s and Sims’s 2011 Prize lectures. While Sargent attempts to use the economic theory to interpret some historical events in order to gain insights on some contemporary issues, such as sovereign defaults, federal bailouts, and the coordination of monetary and fiscal policies, Sims is emphasizing the importance of large-scale economic models and calling for more research to be done in that area.

  15. Effects of irreversibility and economics on the performance of a heat engine

    Ibrahim, O.M.; Klein, S.A.; Mitchell, J.W.


    In this paper, optimization of the power output of an internally irreversible heat engine is considered for finite capacitance rates of the external fluid streams. The method of Lagrange multipliers is used to solve for working fluid temperatures which yield maximum power. Analytical expressions for the maximum power and the cycle efficiency at miximum power are obtained. The effects of irreversibility and economics on the performance of a heat engine are investigated. A relationship between the maximum power point and economically optimum design is identified. It is demonstrated that, with certain reasonable economic assumptions, the maximum power point of a heat engine corresponds to a point of minimum life-cycle costs

  2. Direct measurement of Lorentz transformation with Doppler effects

    Chen, Shao-Guang

    For space science and astronomy the fundamentality of one-way velocity of light (OWVL) is selfevident. The measurement of OWVL (distance/interval) and the clock synchronization with light-signal transfer make a logical circulation. This means that OWVL could not be directly measured but only come indirectly from astronomical method (Romer's Io eclipse and Bradley's sidereal aberration), furthermore, the light-year by definitional OWVL and the trigonometry distance with AU are also un-measurable. For to solve this problem two methods of clock synchronization were proposed: The direct method is that at one end of dual-speed transmissionline with single clock measure the arriving-time difference of longitudinal wave and transverse wave or ordinary light and extraordinary light, again to calculate the collective sending-time of two wave with Yang's /shear elastic-modulus ratio (E/k) or extraordinary/ordinary light refractive-index ratio (ne/no), which work as one earthquake-station with single clock measures first-shake time and the distance to epicenter; The indirect method is that the one-way wavelength l is measured by dual-counters Ca and Cb and computer's real-time operation of reading difference (Nb - Na) of two counters, the frequency f is also simultaneously measured, then l f is just OWVL. Therefore, with classical Newtonian mechanics and ether wave optics, OWVL can be measured in the Galileo coordinate system with an isotropic length unit (1889 international meter definition). Without any hypotheses special relativity can entirely establish on the metrical results. When a certain wavelength l is defined as length unit, foregoing measurement of one-way wavelength l will become as the measurement of rod's length. Let a rigidity-rod connecting Ca and Cb moves relative to lamp-house with velocity v, rod's length L = (Nb - Na) l will change follow v by known Doppler effect, i.e., L(q) =L0 (1+ (v/c) cos q), where L0 is the proper length when v= 0, v• r = v cos q

    Full Text Available The objective of the paper is to investigate whether stock market development plays any role in the effect of foreign direct investment (FDI on economic growth in Nigeria. Using annual time series data that span the period from 1981 to 2014, and employing the fully modified ordinary least squares (FMOLS estimation technique, the empirical evidence indicates that FDI, domestic investment and stock market development positively and significantly affect economic growth, but the effect of the interaction between stock market development and FDI on economic growth is negative and significant, indicating that the Nigerian bourse is not yet fully developed to engender positive growth effect of FDI. The study further finds that government consumption expenditure and trade openness adversely affect the growth of the country’s real GDP per capita. Recommendations of the paper include efforts by the government to design and implement programmes and policies aimed at enhancing the attractiveness of the country to foreign and local investors, efforts by capital market regulators to enhance stock market efficiency, reduction of government consumption expenditures and import control.

  6. Cost-effective conservation planning: lessons from economics.

    Duke, Joshua M; Dundas, Steven J; Messer, Kent D


    Economists advocate that the billions of public dollars spent on conservation be allocated to achieve the largest possible social benefit. This is "cost-effective conservation"-a process that incorporates both monetized benefits and costs. Though controversial, cost-effective conservation is poorly understood and rarely implemented by planners. Drawing from the largest publicly financed conservation programs in the United States, this paper seeks to improve the communication from economists to planners and to overcome resistance to cost-effective conservation. Fifteen practical lessons are distilled, including the negative implications of limiting selection with political constraints, using nonmonetized benefit measures or benefit indices, ignoring development risk, using incomplete cost measures, employing cost measures sequentially, and using benefit indices to capture costs. The paper highlights interrelationships between benefits and complications such as capitalization and intertemporal planning. The paper concludes by identifying the challenges at the research frontier, including incentive problems associated with adverse selection, additionality, and slippage. Copyright © 2013 Elsevier Ltd.

  8. The effect of economic development on population health: a review of the empirical evidence.

    Lange, Simon; Vollmer, Sebastian


    Economic growth is considered an important determinant of population health. Relevant studies investigating the effect of economic growth on health outcomes were identified from Google Scholar and PubMed searches in economics and medical journals. Additional resources generated through economic growth are potentially useful for improving population health. The empirical evidence on the aggregate effect of economic growth on population health is rather mixed and inconclusive. The causal pathways from economic growth to population health are crucial and failure or success in completing the pathways explains differences in empirical findings. Future research should investigate how additional resources can more effectively reach those in need and how additional resources can be used more efficiently. It is particularly relevant to understand why preventive health care in developing countries is very price elastic whereas curative health care is very health inelastic and how this understanding can inform public health policy. © The Author 2017.

  9. System dynamics modelling and simulating the effects of intellectual capital on economic growth

    Ivona Milić Beran


    Full Text Available System dynamics modelling is one of the best scientific methods for modelling complex, nonlinear natural, economic and technical system dynamics as it enables both monitoring and assessment of the effects of intellectual capital on economic growth. Intellectual capital is defined as “the ability to transform knowledge and intangible assets into resources to create wealth for a company and a country.” Transformation of knowledge is crucial. Knowledge increases a country’s wealth only if its importance is recognized and applied differently from existing work practices. The aim of this paper is to show the efficiency of modelling system dynamics and simulating the effects of intellectual capital on economic growth. A computer simulation provided a mathematical model, providing practical insight into the dynamic behavior of the observed system, i.e. the analysis of economic growth and observation of mutual correlation between individual parameters. The results of the simulation are presented in graphical form. The dynamic model of the effects of intellectual capital on Croatia’s economic growth has been verified by comparing simulation results with existing data on economic growth.

  11. Economics of biomass energy utilization in combustion and gasification plants: effects of logistic variables

    Caputo, Antonio C.; Palumbo, Mario; Pelagagge, Pacifico M.; Scacchia, Federica


    The substitution of conventional fossil fuels with biomass for energy production results both in a net reduction of greenhouse gases emissions and in the replacement of non-renewable energy sources. However, at present, generating energy from biomass is rather expensive due to both technological limits related to lower conversion efficiencies, and logistic constraints. In particular, the logistics of biomass fuel supply is likely to be complex owing to the intrinsic feedstock characteristics, such as the limited period of availability and the scattered geographical distribution over the territory. In this paper, the economical feasibility of biomass utilization for direct production of electric energy by means of combustion and gasification-conversion processes, has been investigated and evaluated over a capacity range from 5 to 50 MW, taking into account total capital investments, revenues from energy sale and total operating costs, also including a detailed evaluation of logistic costs. Moreover, in order to evaluate the impact of logistics on the bio-energy plants profitability, the effects of main logistic variables such as specific vehicle transport costs, vehicles capacity, specific purchased biomass costs and distribution density, have been examined. Finally, a mapping of logistic constraints on plant profitability in the specified capacity range has been carried out

  12. The Cost-Effective Laboratory: Implementation of Economic Evaluation of Laboratory Testing

    Bogavac-Stanojevic Natasa


    Full Text Available Laboratory testing as a part of laboratory in vitro diagnostic (IVD has become required tool in clinical practice for diagnosing, monitoring and prognosis of diseases, as well as for prediction of treatment response. The number of IVD tests available in laboratory practice has increased over the past decades and is likely to further increase in the future. Consequently, there is growing concern about the overutilization of laboratory tests and rising costs for laboratory testing. It is estimated that IVD accounts for between 1.4 and 2.3% of total healthcare expenditure and less than 5% of total hospital cost (Lewin Group report. These costs are rather low when compared to pharmaceuticals and medical aids which account for 15 and 5%, respectively. On the other hand, IVD tests play an important role in clinical practice, as they influence from 60% to 70% of clinical decision-making. Unfortunately, constant increases in healthcare spending are not directly related to healthcare benefit. Since healthcare resources are limited, health payers are interested whether the benefits of IVD tests are actually worth their cost. Many articles have introduced frameworks to assess the economic value of IVD tests. The most appropriate tool for quantitative assessment of their economic value is cost-effectiveness (CEA and cost-utility (CUA analysis. The both analysis determine cost in terms of effectiveness or utilities (combine quantity and quality of life of new laboratory test against its alternative. On the other hand, some investigators recommended calculation of laboratory test value as product of two ratios: Laboratory test value = (Technical accuracy/Turnaround time × (Utility/Costs. Recently, some researches used multicriteria decision analysis which allows comparison of diagnostic strategies in terms of benefits, opportunities, costs and risks. All analyses are constructed to identify laboratory test that produce the greatest healthcare benefit with

  13. Direct anthelmintic effects of condensed tannins from diverse plant sources against Ascaris suum.

    Andrew R Williams

    Full Text Available Ascaris suum is one of the most prevalent nematode parasites in pigs and causes significant economic losses, and also serves as a good model for A. lumbricoides, the large roundworm of humans that is ubiquitous in developing countries and causes malnutrition, stunted growth and compromises immunity to other pathogens. New treatment options for Ascaris infections are urgently needed, to reduce reliance on the limited number of synthetic anthelmintic drugs. In areas where Ascaris infections are common, ethno-pharmacological practices such as treatment with natural plant extracts are still widely employed. However, scientific validation of these practices and identification of the active compounds are lacking, although observed effects are often ascribed to plant secondary metabolites such as tannins. Here, we extracted, purified and characterised a wide range of condensed tannins from diverse plant sources and investigated anthelmintic effects against A. suum in vitro. We show that condensed tannins can have potent, direct anthelmintic effects against A. suum, as evidenced by reduced migratory ability of newly hatched third-stage larvae and reduced motility and survival of fourth-stage larvae recovered from pigs. Transmission electron microscopy showed that CT caused significant damage to the cuticle and digestive tissues of the larvae. Furthermore, we provide evidence that the strength of the anthelmintic effect is related to the polymer size of the tannin molecule. Moreover, the identity of the monomeric structural units of tannin polymers may also have an influence as gallocatechin and epigallocatechin monomers exerted significant anthelmintic activity whereas catechin and epicatechin monomers did not. Therefore, our results clearly document direct anthelmintic effects of condensed tannins against Ascaris and encourage further in vivo investigation to determine optimal strategies for the use of these plant compounds for the prevention and

    Wlodarczyk, T.L.; Flynn, B.


    The Port Hope Area Initiative (PHAI) is a community-based program directed at the development and implementation of a safe, long-term management solution for low-level radioactive waste (LLRW) that has existed in two communities in the Port Hope area for some seven decades. As part of the environmental assessment of the two projects (i.e., the Port Hope Project and the Port Granby Project) being undertaken as part of the PHAI, two separate socio-economic effects assessments were completed. The assessments were designed to be broad ranging assessments of the effects of the Projects on people and their communities. This paper discusses how the assessments identified and assessed the positive and negative effects of the two Projects, what those effects were, and draws conclusions on whether the positives outweigh the negatives.

    D. D. Burkaltseva


    strategic tasks in the sphere of regional development: increasing the competitiveness of regions and strengthening their resource potential; Development of human resources; Development of interregional cooperation; Creation of institutional conditions for the development of regions. For effective management of processes and making correct timely decisions, it is necessary to monitor the indicators by creating situational centers in the regions based on the Internet of things and closed blokchain. As preventive measures, it is necessary to create a communication system for direct and feedback to provide software for monitoring financial and economic security at the level of an economic entity on-line. This provision is proposed to develop, maintain, monitor, systematically update at the regional and state level for a timely response in the effective targeted use of small and young business financing by the state. For effective uninterrupted functioning at the level of business entities, economic entities use the Internet of things. At the same time, an inalienable and important model is the construction of an effective interaction between the subjects of the "business-power" system. Further research should be directed to the systematization of monitoring indicators of financial and economic security at the level of an economic entity on-line. Development and implementation of pilot projects on the use of Internet stuff and blokchain in the public sector, their institutional support, their impact on the regional gross product.  

  17. Making NEPA more effective and economical for the new millennium



    This paper focuses on a ten-element strategy for streamlining the NEPA process in order to achieve the Act's objectives while easing the considerable burden on agencies, the public, and the judicial system. In other words, this paper proposes a strategy for making NEPA work better and cost less. How these ten elements are timed and implemented is critical to any successful streamlining. The strategy elements discussed in this paper, in no particular order of priority, are as follows: (1) integrate the NEPA process with other environmental compliance and review procedures; (2) accelerate the decision time for determining the appropriate level of NEPA documentation; (3) conduct early and thorough internal EIS (or EA) scoping before public scoping or other public participation begins; (4) organize and implement public scoping processes that are more participatory than confrontational; (5) maintain an up-to-date compendium of environmental baseline information; (6) prepare more comprehensive, broad-scope umbrella EISs that can be used effectively for tiering; (7) encourage preparation of annotated outlines with detailed guidance that serve as a road map for preparation of each EIS or EA; (8) decrease the length and complexity of highly technical portions of NEPA documents; (9) increase and systematize NEPA compliance outreach, training, and organizational support; and (10) work diligently to influence the preparation of better organized, shorter, and more readable NEPA documents.

  18. Economic importance of ticks and their effective control strategies

    Haranahalli Vasanthachar Manjunathachar


    Full Text Available Role of livestock in improvement of a country ’s economy is inevitable. Livestock contributes a lion ’s share in agricultural sector of developing countries. Several developing countries have adopted the use of exotic germplasm to improve the productivity of their native breeds, which has brought down the disease resistance. Among various problems hindering the growth and productivity of livestock, parasite related problem plays a major role. Tick and tick borne diseases are prevalent in 80% of the cattle population around the globe. They cause various worries to the farmers by transmitting major disease causing pathogens and jeopardize animal health leading to poor production. Ticks transmit various pathogenic agents like virus, bacteria, protozoa and other parasites as well. Many of them are dangerous for the livestock health and some are also zoonotic hence, need to be checked at the initial stages. Control of ticks is the major concern in the present situation as the use of anti-parasitic drugs has led to the current trend of resistance development. Search for an effective alternative method has begun; vaccination will be a better alternative and promising tool for protecting livestock from the tick infestations and thereby tick borne diseases.

  19. Quantitative and economical assessment of effectiveness of electrostatic pesticide spraying

    Nishimura, Ryo; Fujita, Satoko; Michihara, Shota; Masuoka, Takashi; Kimura, Toshihiro; Yatsuzuka, Shinji; Anaguchi, Shinobu


    Electrostatic pesticide spraying (EPS) improves the adhesion characteristics of the pesticide solution to agricultural crops. If the adhesion characteristics are improved, the requisite amount of the pesticide to be sprayed can be reduced in comparison with the conventional spraying method that uses non-charged pesticide. In this research, disease (rust) control experiments were carried out to substantiate the effectiveness of the EPS from a statistical point of view. We sprayed pesticide to potted Japanese pear trees under calm condition. The numbers of the rust lesions on the pear leaves were counted at fixed intervals after spraying to investigate the difference of the results of the disease control. The t-tests were carried out for the populations of the various spraying times and applied voltages. It was statistically-derived that EPS can reduce the amounts of pesticide to be sprayed by 50 % in comparison with the non-EPS method. It is also estimated from the results that about 55,000 kL year −1 of pesticides can be reduced for the Japanese pear cultivation in Tottori prefecture. Also, this means that the expense of the pear cultivation can be reduced by about 240 million yen (3 million USD) every year in Tottori prefecture by introducing EPS.

  20. The economic costs of radiation-induced health effects: Estimation and simulation

    Nieves, L.A.; Tawil, J.J.


    This effort improves the quantitative information available for use in evaluating actions that alter health risks due to population exposure to ionizing radiation. To project the potential future costs of changes in health effects risks, Pacific Northwest Laboratory (PNL) constructed a probabilistic computer model, Health Effects Costs Model (HECOM), which utilizes the health effect incidence estimates from accident consequences models to calculate the discounted sum of the economic costs associated with population exposure to ionizing radiation. Application of HECOM to value-impact and environmental impact analyses should greatly increase the quality of the information available for regulatory decision making. Three major types of health effects present risks for any population sustaining a significant radiation exposure: acute radiation injuries (and fatalities), latent cancers, and impairments due to genetic effects. The literature pertaining to both incidence and treatment of these health effects was reviewed by PNL and provided the basis for developing economic cost estimates. The economic costs of health effects estimated by HECOM represent both the value of resources consumed in diagnosing, treating, and caring for the patient and the value of goods not produced because of illness or premature death due to the health effect. Additional costs to society, such as pain and suffering, are not included in the PNL economic cost measures since they do not divert resources from other uses, are difficult to quantify, and do not have a value observable in the marketplace. 83 refs., 3 figs., 19 tabs
