    Full Text Available The goal of this research is to analyze developments in employment and employment characteristics during the current crisis in Croatia. The main findings can be summarized as follows: (1 The primary (aggregate mode of adjustment to the crisis was a decline in employment. There are, however, considerable differences in adjustment patterns across economic activities. (2 During the crisis, jobs were lost in the, more dynamic, private sector, while the number of jobs in the public sector (entities in state ownership slightly increased. (3 Economic activities with comparatively larger shares of women in employment have experienced fewer employment cuts and the aggregate employment share of women rose during the crisis, especially in activities with a larger share of public sector workers.(4 There has been a declining share of younger workers during the crisis, justifying policy actions to facilitate their employment. (5 Employees with comparatively lower educational attainment face severe challenges in the labor market, which is a longer term trend, not specific to the crisis period. There are indications that this group of employees enjoys a higher level of protection in the public sector. (6 Analysis also shows a rising significance of more flexible forms of employment: increasing shares of fixed term employees (during the last two observed years, and of part time workers. (7 Working hours do not exhibit any strong trends specific to the crisis, except for the diminishing number of overtime hours per worker.

    2012-01-01

    This study uses microeconomic data from the transportation systems of land cargo in Colombia: rail and trucking, to determine their degree of allocative efficiency through the non-parametric method Data Envelopment Analysis DEA. The average overall efficiency found was 74.4% for trains and 20.56% for trucks. These figures indicate that rail is more efficient in the allocation of resources. This means that trains in Colombia use their input better than trucks to maximize their production, given the costs and technological characteristics of each system. This is a signal for the design of a public policy for investment in transportation infrastructure that seeks to raise the competitiveness of Colombian exports, investing not only in roads but in complementary systems such as railways too. - Highlights: ► Colombia is currently undergoing a backlog of transport infrastructure and high export costs. ► We perform a microeconomic study of transportation systems in Colombia: rail and trucking. ► As a result we found that the rail is much more efficient than the automotive system. ► As policy recommendation the government should consider the investment in railways. ► It is necessary to take into account the strategic value that investment in railways would bring.

  13. Effects of tillage practice on soil structure, N2O emissions and economics in cereal production under current socio-economic conditions in central Bosnia and Herzegovina.

    Conservation tillage is expected to have a positive effect on soil physical properties, soil Carbon (C) storage, while reducing fuel, labour and machinery costs. However, reduced tillage could increase soil nitrous oxide (N2O) emissions and offset the expected gains from increased C sequestration. To date, conservation tillage is barely practiced or studied in Bosnia and Herzegovina (BH). Here, we report a field study on the short-term effects of reduced (RT) and no tillage (NT) on N2O emission dynamics, yield-scaled N2O emissions, soil structure and the economics of cereal production, as compared with conventional tillage (CT). The field experiment was conducted in the Sarajevo region on a clayey loam under typical climatic conditions for humid, continental BH. N2O emissions were monitored in a Maize-Barley rotation over two cropping seasons. Soil structure was studied at the end of the second season. In the much wetter 2014, N2O emission were in the order of CT > RT > NT, while in the drier 2015, the order was RT > CT > NT. The emission factors were within or slightly above the uncertainty range of the IPCC Tier 1 factor, if taking account for the N input from the cover crop (alfalfa) preceding the first experimental year. Saturated soils in spring, formation of soil crusts and occasional droughts adversely affected yields, particularly in the second year (barley). In 2014, yield-scaled N2O emissions ranged from 83.2 to 161.7 g N Mg-1 grain (corn) but were much greater in the second year due to crop failure (barley). RT had the smallest yield-scaled N2O emission in both years. NT resulted in economically inacceptable returns, due to the increased costs of weed control and low yields in both years. The reduced number of operations in RT reduced production costs and generated positive net returns. Therefore, RT could potentially provide agronomic and environmental benefits in crop production in BH.

  14. Current Economic Situation in Bosnia and Herzegovina

    2011-11-01

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

    Current economic trends in equine practice are trends of weakness. Most practices, after a decade of double-digit growth, have migrated to survival mode within a few months. Understanding that all regions and disciplines are affected differently, using the Porter five forces model, we can identify changes that must be made in our business models first to survive and then to position ourselves to prosper when the recession ends. If we are to avoid long-term damage to our practices, we must use cost control and work efficiency in addition to price concessions.

    Full Text Available The objective of this study was to develop a total economic merit index that identifies more profitable animals using Portugal as a case study to illustrate the recent economic changes in milk production. Economic values were estimated following future global prices and EU policy, and taking into consideration the priorities of the Portuguese dairy sector. Economic values were derived using an objective system analysis with a positive approach, that involved the comparison of several alternatives, using real technical and economic data from national dairy farms. The estimated relative economic values revealed a high importance of production traits, low for morphological traits and a value of zero for somatic cell score. According to several future market expectations, three scenarios for milk production were defined: a realistic, a pessimistic and an optimistic setting, each with projected future economic values. Responses to selection and efficiency of selection of the indices were compared to a fourth scenario that represents the current selection situation in Portugal, based on individual estimated breeding values for milk yield. Although profit resulting from sale of milk per average lactation in the optimistic scenario was higher than in the realistic scenario, the volatility of future economic conditions and uncertainty about the future milk pricing system should be considered. Due to this market instability, genetic improvement programs require new definitions of profit functions for the near future. Effective genetic progress direction must be verified so that total economic merit formulae can be adjusted and selection criteria redirected to the newly defined target goals.

  2. Organisational Pathologies Under Conditions of Economic Downswing

    2017-06-01

    Full Text Available The topic of organisational pathology is surprisingly absent in literature on management, especially when bearing in mind the theoretical and practical import of such questions. The intention of the author is to fill in this gap, at least partially. The paper is based on an analysis of literature and an empirical research conducted by the author. The research applied partially structured interviews as its method. These interviews were conducted with entrepreneurs and managers of various levels. They made possible the drawing of conclusions relating to conditions behind the genesis and growth of selected organisational pathologies in a situation of economic downswing. The article briefly presents the concept and influence of pathology on the functioning of an organisation. The author concentrates on the causes of the phenomenon and presents them from various perspectives. It is during times of economic downswing that an increase in unethical behaviour, including corruption, mobbing as well as others, becomes particularly visible. Also noticeable is concentrating on limiting costs, which can sometimes reach pathological scale. This can lead to a permanent loss of pro-development potential by the organisation. Moreover, numerous pathological phenomena emerge at the tangent point of the organisation and its surroundings. The source of many undesirable phenomena in the organisation and in its relations with its surroundings is a fall in trust, which makes its appearance in crisis situations. More often than not, managers facing a situation in which they have no choice perpetuate organisational pathologies, whilst, at the same time, being aware of the lack of validity of their actions. However, a more frequent source of problems is the differences in perspective in perceiving organisational phenomena by various actors and stakeholders.

    One of the main questions in electricity market deregulation is the aptitude of private capital for investments in power generation. This is especially important in Brazil, whose load has a strong growth trend ({approx}6% per year). Thermopower is an attractive alternative for expanding generation, as it is complementary in many aspects to hydropower, which supplies most Brazil's power at a very low price most of the time, but makes the system vulnerable to seasonal water variations. This paper studies the competitiveness of thermopower generation in Brazil under current regulations; assesses under the real options theory approach the conditions for investments in thermopower generation, and finally presents and discusses a hydropower generation schedule model.

  11. Economic Conditions and Factors Affecting New Nuclear Power Deployment

    Harrison, Thomas J [ORNL

    2014-10-01

    This report documents work performed in support of the US Department of Energy Office of Nuclear Energy’s Advanced Small Modular Reactor (AdvSMR) program. The report presents information and results from economic analyses to describe current electricity market conditions and those key factors that may impact the deployment of AdvSMRs or any other new nuclear power plants. Thus, this report serves as a reference document for DOE as it moves forward with its plans to develop advanced reactors, including AdvSMRs. For the purpose of this analysis, information on electricity markets and nuclear power plant operating costs will be combined to examine the current state of the nuclear industry and the process required to successfully move forward with new nuclear power in general and AdvSMRs in particular. The current electricity market is generally unfavorable to new nuclear construction, especially in deregulated markets with heavy competition from natural gas and subsidized renewables. The successful and profitable operation of a nuclear power plant (or any power plant) requires the rate at which the electricity is sold to be sufficiently greater than the cost to operate. The wholesale rates in most US markets have settled into values that provide profits for most operating nuclear power plants but are too low to support the added cost of capital recovery for new nuclear construction. There is a strong geographic dependence on the wholesale rate, with some markets currently able to support new nuclear construction. However, there is also a strong geographic dependence on pronuclear public opinion; the areas where power prices are high tend to have unfavorable views on the construction of new nuclear power plants. The use of government-backed incentives, such as subsidies, can help provide a margin to help justify construction projects that otherwise may not seem viable. Similarly, low interest rates for the project will also add a positive margin to the economic

    Full Text Available The article is devoted to the transformation of the energy strategy of Russia in the conditions of the current economic crisis. The special attention is paid to current trends in the sphere of international relations having a decisive influence on the formation of Russia’s energy strategy. The authors point to the crisis of the modern world, the deepening of interstate contradictions, the expansion of confrontation, the revision of the uniform principles of trade, established by the World Trade Organization, the changes in the global financial system. The authors investigate the possibility of political arrangements between the leading suppliers of oil on the destabilization of the oil market in order to achieve geopolitical goals. In the article special attention is also paid to the issue of political motivation of anti-Russian sanctions directed at impeding Russia’s development and its Fuel & Energy Complex, in particular. Today, against the background of the current political situation, the energy strategy of Russia is exposed to adjustment. The country has the important task of ensuring technological independence of the energy sector on the basis of import substitution of the equipment, diversification of the directions of export of energy resources, preservation of leading positions in the world market of peaceful nuclear energy, etc. The authors conclude that the energy strategy of Russia is important part of foreign policy strategy of the country, and it is focused on practical cooperation with all countries and is aimed at protecting interests of the state.

    Full Text Available Currently, the vaccination not only does not lose its value, but also becoming more in-demand allowing to prevent mass infection, disability, and mortality due to them, oncological and somatic diseases. The variety of medicinal vaccines is actively developed. The particular importance is given to the vaccination as a key mean to prevent the antibiotic resistance. That is why it is important for every health worker to know the up-to-date approaches to the immunization in whole, and especially for the risk groups, to understand and compare reasonably the risks of the infections and vaccinations, to be able to explain this to their patients and parents. The most important is a common understanding of the importance of the preventive vaccination of the health workers of all specialties and levels.

    2015-01-01

    Full Text Available The article considers national economic interests that form the basis of national security (food, raw materials, finance, infrastructure including transport and set the priorities for the development of economic sectors (industry, scientific and technological development, entrepreneurship, social sector and innovation development. The authors carry out brief analysis for each type of national economic interests and find out how they are reflected in the national documents on socio-economic development and in international documents on economic cooperation with Russia’s participation. These interests in the national aspect are reflected in the Concept for long-term socio-economic development, and in the strategies and state programs for development of economic sectors. As for the international economic aspect, the authors consider Russia’s contracts with individual countries on trade and/or cooperation, the Agreement on the Eurasian Economic Union, the Declaration and agreements of the BRICS countries, the Program for Trade and Economic cooperation between the SCO countries, and international standards relating to socio-economic ratings and indexes. The analysis shows that the country requires the development of a unified conceptual project that would link strategic priorities of socio-economic development of the Russian Federation with changing geoeconomic conditions. This independent project should represent a set of system strategic guidelines on different levels, enhancing the role and increasing the importance of Russia in the new architecture of the geo-economic world order, the country’s participation in the joint strategies implemented by the Russian Federation together with other interested countries and new integration groups, and also defending conceptual interests of national development

    Extant analyses of the relation between economic conditions and population health were often based on annualized data and were susceptible to confounding by nonlinear time trends. In the present study, the authors used generalized additive models with nonparametric smoothing splines to examine the association between economic conditions, including levels of economic activity in New York State and the degree of volatility in the New York Stock Exchange, and monthly rates of death by suicide in New York City. The rate of suicide declined linearly from 8.1 per 100,000 people in 1990 to 4.8 per 100,000 people in 1999 and then remained stable from 1999 to 2006. In a generalized additive model in which the authors accounted for long-term and seasonal time trends, there was a negative association between monthly levels of economic activity and rates of suicide; the predicted rate of suicide was 0.12 per 100,000 persons lower when economic activity was at its peak compared with when it was at its nadir. The relation between economic activity and suicide differed by race/ethnicity and sex. Stock market volatility was not associated with suicide rates. Further work is needed to elucidate pathways that link economic conditions and suicide.

    Full Text Available The article is devoted to the study of the problem of economic growth in Armenia. It is identified the nature of the balance of payments of the country, indicating a net debtor position, which leads to inherent deterioration of the international investment position. A small open economy of Armenia moves to a new phase of development, in the frame of the integration processes within the Customs Union and the Eurasian Economic Union of Russia, Belarus and Kazakhstan. One of the main characteristics of the Armenian economy vulnerability remains a negative balance in foreign trade, which continues to grow, despite the export growth. Economic growth is provided, as before, mostly due to the sale of raw materials - non-ferrous metals and metal ores, both in the primary as well as in the previous preprocessing. Estimating the econometric VAR models revealed that the negative current account impacts on GDP growth negatively.

  1. Technical conditions for sustainable growth in economic theory. An analysis

    Granda C, Catalina

    2008-01-01

    Economic theory and its models point out returns to scale, substitution among productive factors and technological progress as conditions for sustainable growth. This work aims at a critical appraisal of these conditions, particularly the ones related to substitution between natural resources and manmade capital and technical change, by recognizing the inevitable physical scarcity of resources concomitant to the human actions in a world governed by hemodynamic restrictions. To do so, the role that the mentioned conditions play in the theories of economic growth with resources is analyzed, and its limitations and objections from a biophysical perspective are indicated as well. Finally, a brief consideration as to how inappropriate the theoretical representations of economic activities are to take account of growth in spite of resource exhaustion or degradation is carried out

  2. The current Russian model of social development, and economic growth

    Directory of Open Access Journals (Sweden)

    V V Paramonov

    2016-12-01

    Full Text Available Although the Article 7 of the Constitution of Russia adopted in 1993 defines the country as a social state, the contemporary social and economic situation is significantly different from this declaration. The author considers the current situation focusing on the foundations of the welfare state. The indicators of social inequality and stratification that allow to identify the country as a social state prove the widening gap between the rich and poor. In recent years, nothing has been done to achieve the more equitable distribution of income and national wealth, which led to the further growth of social inequality exceeding the global indices. The author believes that the high level of social inequality negatively affects the economic growth. Based on the studies of Russian scientists he concludes that equal distribution of income provides higher rates of economic growth and prosperity of the country. The modified theory of the factors of production explains this interconnection, and adds a few more factors, including such a specific resource as sales market, to three factors introduced by J.B. Say at the beginning of the XIX century. The huge social inequality and, consequently, a significant number of the poor deprive the country of such an important resource. To change the situation, the author proposes to return to the progressive tax scale and introduce the zero rate of income tax for the poorest groups in order to create prerequisites for the growth of consumer demand under the economic crisis.

    In a building project, several subsystems are designed, among them the air conditioning system. Electrical energy consumption profiles show that this subsystem is responsible for 40 to 50% of total consumption in a commercial building. Besides the study of technical aspects that should be considered in order to assure the thermal comfort of the occupants as well the temperature and humidity conditions for an efficient equipment operation, an economical evaluation of this subsystem should be also made. In retrofit projects, the economical aspect is also critical for such projects in order to assure bigger efficiency in an economically attractive way. This paper analyses some strategies that might be adopted in retrofitting an air conditioning system installed in a commercial building with mixed occupation. By mixed we mean that some floors have a typical office occupation profile and other floors are mainly occupied by electronic equipment. This analysis includes both technical and economical evaluation. The proposed solutions performance are compared to the old system, which allows to verify the retrofitting impact in energy consumption reduction and its economical feasibility. (author)

  7. New approaches to business cycle theory in current economic science

    2012-07-01

    Full Text Available In modern economies, current research generally acknowledges that the central issues in macroeconomics are essentially the same as those identified by Keynes in the General Theory of Employment, Interest and Money. One way or the other, economists are trying to address the same macroeconomic issues that they did seven decades ago: How can we account for the different growth rates and various fluctuations observed in national economies? Which are the economic policies most suitable to solve the issues of growth and cyclic behavior? Both the new classicals and the new Keynesians have made considerable progress within their research paradigms: to explain economic fluctuations, the new classicals focus on technological perturbations, the intertemporal substitution of leisure and real business cycles; on the other hand, the new Keynesians speak in terms of monopolistic competition, menu costs or efficiency wages. On the whole, the new classicals believe that the business cycle can best be understood within the market-clearing model, whereas the new keynesians believe that business fluctuations are due to certain market failures of various sorts.The present paper focuses on the main directions of research of the new classical school on the business cycle, given that the theoretical progress in this field has been significant and relevant for economic policy during the past four decades.

The national economic securitystabilitycan be estimated only by the application of elaborate tools of the economic development indicators analysis and the threshold values examinationaimed at the determination of the quality characteristic of actual and the most successful model of the economic activity.The analysis of the current Russian economic situation showed the presence of some serious problems existing in the national economy. The economic security level of Russia, having a tendency to increase in the period of 1998-2013, has been sharply reduced to critical points since 2014. So, it is necessary to take some measures to restructure the system of economic security of the state. Based on the research it was identified the list of the most dangerous threats to the modern Russian economy, which includes: low level of the country industrial production; the economy dependence on goods import and raw materials export; low living standards of the population; the rapid growth of the shadow economy and corruption; the lack of civil science and innovationdevelopment. The main strategic directions for economic security levelincrease in Russia today and in the future are aimed at

    2013-09-01

    This article reviews psychology and behavioral economic approaches to HIV prevention, and examines the integration and application of these approaches in conditional economic incentive (CEI) programs for reducing HIV risk behavior. We discuss the history of HIV prevention approaches, highlighting the important insights and limitations of psychological theories. We provide an overview of the theoretical tenets of behavioral economics that are relevant to HIV prevention, and utilize CEIs as an illustrative example of how traditional psychological theories and behavioral economics can be combined into new approaches for HIV prevention. Behavioral economic interventions can complement psychological frameworks for reducing HIV risk by introducing unique theoretical understandings about the conditions under which risky decisions are amenable to intervention. Findings from illustrative CEI programs show mixed but generally promising effects of economic interventions on HIV and sexually transmitted infection (STI) prevalence, HIV testing, HIV medication adherence, and drug use. CEI programs can complement psychological interventions for HIV prevention and behavioral risk reduction. To maximize program effectiveness, CEI programs must be designed according to contextual and population-specific factors that may determine intervention applicability and success.

It is often argued that personalizing treatment will inevitably improve clinical outcomes for patients and help achieve more effective use of health care resources. Demand is increasing for demonstrable evidence of clinical and cost-effectiveness to support the use of personalized medicine in health care. This paper begins with an overview of the existing challenges in conducting economic evaluations of genetics- and genomics-targeted technologies, as an example of personalized medicine. Our paper illustrates the complexity of the challenges faced by these technologies by highlighting the variations in the issues faced by diagnostic tests for somatic variations, generally referring to genetic variation in a tumor, and germline variations, generally referring to inherited genetic variation in enzymes involved in drug metabolic pathways. These tests are typically aimed at stratifying patient populations into subgroups on the basis of clinical effectiveness (response or safety (avoidance of adverse events. The paper summarizes the data requirements for economic evaluations of genetics and genomics-based technologies while outlining that the main challenges relating to data requirements revolve around the availability and quality of existing data. We conclude by discussing current developments aimed to address the challenges of assessing the cost-effectiveness of genetics and genomics-based technologies, which revolve around two central issues that are

    Perales, Francisco; Plage, Stefanie

    2017-02-01

    Medical research shows that healthy sleep has benefits for human wellbeing. We contribute to the emerging social-epidemiological literature on the social determinants of sleep by considering how living in an area with poor economic circumstances can result in sleep loss through financial worry, uncertainty and stress. We use multilevel regression models and nationally-representative data from the Household, Income and Labour Dynamics in Australia Survey (n = 9181) and find that individuals who live in areas with high unemployment rates or experience individual-level economic vulnerability sleep less than comparable individuals in areas with low unemployment rates, or who do not experience financial hardships. The negative association between local economic conditions and sleep duration is substantially stronger amongst economically vulnerable individuals. This highlights the importance of considering multiple levels in the analysis of health inequalities, as status and location can intersect to produce and reproduce disadvantage systems.

  15. Stock markets and criticality in the current economic crisis

    Science.gov (United States)

    da Silva, Roberto; Zembrzuski, Marcelo; Correa, Fabio C.; Lamb, Luis C.

    2010-12-01

    We show that the current economic crisis has led the market to exhibit a non-critical behavior. We do so by analyzing the quantitative parameters of time series from the main assets of the Brazilian Stock Market BOVESPA. By monitoring global persistence we show a deviation of power law behavior during the crisis in a strong analogy with spin systems (from where this concept was originally conceived). Such behavior is corroborated by an emergent heavy tail of absolute return distribution and also by the magnitude autocorrelation exponent. Comparisons with universal exponents obtained in the international stock markets are also performed. This suggests how a thorough analysis of suitable exponents can bring a possible way of forecasting market crises characterized by non-criticality.

    Full Text Available The Middle East and North Africa (MENA is an economically diverse region that includes countries with a common heritage, at various stages of economic development, with vastly different endowment of natural resources and accounts for 6% of the world total population. Despite undertaking economic reforms in many countries, and having considerable success in achieving macroeconomic stability, the region's economic performance in the past 30 years has been below its potential. Some countries that pursued reforms, such as Egypt, Jordan, Morocco, and Tunisia, enjoyed the region's most rapid growth rates, but due to the political instability and turbulences they are still lagged behind. The purpose of this study is to empirically investigate the impact of globalization in MENA region on the economic performances. This study uses a panel data covers the period 2001–2014 for Gulf Cooperation Council (GCC and non- Gulf Cooperation Council (non-GCC MENA countries and employs Generalized Method of Moments (GMM approach. Results indicate that Globalization is negatively affecting economic conditions in non-GCC and it has no significant effect on non-GCC. This study suggests better policy coordination at all level of government to integrate social, economic and political policies as well all to improve transparency and democratic participation. The paper is outlined as follows- following the introduction, section two reviews the current economic conditions in MENA countries, section three discusses data and methodology, section four presents’ results and interpretation of findings, section five provides conclusions and recommendations.

    Arkes, Jeremy

    2012-03-01

    This paper examines whether youth cigarette use increases during weak economic periods (as do youth alcohol and drug use). The data come from the 1997 National Longitudinal Survey of Youth. With repeated measures over the 1997-2006 period, for almost 9,000 individuals, the samples include 30,000+ teenagers (15-19 years) and 30,000+ young adults (20-24 years). Logit models with state and year controls are estimated. The results indicate that teenagers and young adults increase cigarette use when the economy is weaker, implying that the current financial crisis has likely increased youth cigarette use relative to what it would have otherwise been.

    2014-10-01

    Interest for nuclear energy had resurgence since the beginning of the new century. This was a consequence of the new world conditions and needs: increasing energy demands (mainly from developing countries), awareness of the importance of energetic security and the necessity of limiting carbon emissions. In this nuclear boom, Small Modular Reactors (SMRs) develop and start to consolidate as a viable option for the present energy market. Their modular characteristics, lower initial capital cost, passive safety features and their niche applications, situate them as a technology with various advantages. The following study will present and analysis that will help to comprehend the SMRs present status. Information will show planned reactors, reactors in construction and in operation, advantages and challenges of their implementation, relevant economic aspects and important licensing factors that need to be highlighted. The analysis showed that the SMR technology is still in an initial stage that could reach and important development point in the next ten years. In this period, many of the reactors that are in design stage or that are through their licensing process might be constructed and could be getting ready for a commercial status. On the other hand, it has been observed that there are two main economic factors that need to be considered for any SMRs implementation project. First, the costs (initial, operation, maintenance, fuel and decommissioning) and second their possible niche market applications. Additionally, it has been noted that the licensing process is one of the greatest challenges for SMR general development. Licensing is mainly related to topic such as Emergency Planning Zone, first-of-a-kind engineering, passive safety features, proliferation resistance, multiple module designs and staffing. Previous information will serve as a base for carrying out a feasibility assessment analysis for SMR in Mexico. This part will be the last section of the project

    Full Text Available Fiscal policies in the current era are the sovereign right of states to collect and administer taxes on national territory. In this respect, the European Union, which is an association of independent states, did not created an European tax - although many politicians proposing it - and within the Union is found important differences between the tax systems of member states. Due to historical and national different traditions, the EU member states have heterogeneous tax systems and revenue sharing systems because of different conceptions of public policies relative to the role of state in social and economic respective community’s life. The financing of public spending is usually considered the main function of taxation. In the original tradition following Locke1, property protection is the main functions of the state. As a result, the tax must correspond to the services rendered, that is to say, to pay the State for the protection of the rights it provides. Here we are at the origin of the doctrine of the benefit that there should be equivalence between the utility derived by the citizens of public services they consume and the "price" they pay tax.

    Full Text Available During non-severe fault conditions, crowbar protection is not activated and the rotor windings of a doubly-fed induction generator (DFIG are excited by the AC/DC/AC converter. Meanwhile, under asymmetrical fault conditions, the electrical variables oscillate at twice the grid frequency in synchronous dq frame. In the engineering practice, notch filters are usually used to extract the positive and negative sequence components. In these cases, the dynamic response of a rotor-side converter (RSC and the notch filters have a large influence on the fault current characteristics of the DFIG. In this paper, the influence of the notch filters on the proportional integral (PI parameters is discussed and the simplified calculation models of the rotor current are established. Then, the dynamic performance of the stator flux linkage under asymmetrical fault conditions is also analyzed. Based on this, the fault characteristics of the stator current under asymmetrical fault conditions are studied and the corresponding analytical expressions of the stator fault current are obtained. Finally, digital simulation results validate the analytical results. The research results are helpful to meet the requirements of a practical short-circuit calculation and the construction of a relaying protection system for the power grid with penetration of DFIGs.

    Full Text Available ABSTRACT The citriculture consists in several environmental risks, as weather changes and pests, and also consists in considerable financial risk, mainly due to the period ofreturn on the initial investment. This study was motivated by the need to assess the risks of a business activity such as citriculture. Our objective was to build a stochastic simulation model to achieve the economic and financial analysis of an orange producer in the Midwest region of the state of Sao Paulo, under conditions of uncertainty. The parameters used were the Net Present Value (NPV, the Modified Internal Rate of Return(MIRR, and the Discounted Payback. To evaluate the risk conditions we built a probabilistic model of pseudorandom numbers generated with Monte Carlo method. The results showed that the activity analyzed provides a risk of 42.8% to reach a NPV negative; however, the yield assessed by MIRR was 7.7%, higher than the yield from the reapplication of the positive cash flows. The financial investment pays itself after the fourteenth year of activity.

    2018-01-01

    Full Text Available Introduction. The active development of integration processes causes the necessity of applying high-level approaches to management of the banking system, which is an essential part of the financial sector. Due to the importance of credit operations in the portfolio of banking assets, development of efficient and flexible credit management system is the basis for financial and market stability of banks. Purpose. Analyze the condition of the credit portfolio of banking institutions under the influence of economic processes and make conclusions and recommendations about the effectiveness of managing the bank’s credit portfolio and generalize ways of improving the structure and quality of the bank’s credit portfolio. Results. Over the last six years, the quality of the credit portfolio has become worse because of the bad debts growing and, as a result, decreasing in revenues. The calculated coefficient of management efficiency of a credit portfolio shows the dependence of this indicator on the value of risk and yield. In order to confirm the dependence and determine the degree of influence of these indicators on the efficiency of management of a loan portfolio, an economic-mathematical model was constructed on the example of both individual banks and the banking system as a whole. Detected dependence of factors is quite logical, therefore, the model can be recommended for practical use. Conclusion. Using this method of determining the management efficiency of a credit portfolio will allow the management of the bank to make reasonable decisions. It will allow the possibility of forming a more justified credit portfolio, taking into account not only the profitability, but also the real level of risk of credit operations.

    Full Text Available The employment-productivity-salary correlation is essential towards setting up conditions for economic growth andlasting social stability. An influence exists from technological changes, current stage of economic development,peculiarities of labour offer, employers – trade-unions interaction, etc. The analysis covers long-term and short-termcycles. In keeping with specificity of development stages, national economy witnesses an interval of productivitygrowth facilitating maximized employment and a rise in salary too. A lower growth rate indicates difficulties inassimilating new technologies; a higher growth rate generates instability in employing labour. Thus, the exercise ofstrong pressure is shown to exist on economic and technological structures. Likewise, this is what happens whenproductivity goes ahead of the separate analyses of the correlations between employment and productivity, on theone hand, and productivity and salary, on the other.

  16. Condition monitoring of machinery using motor current signature analysis

    International Nuclear Information System (INIS)

    Kryter, R.C.; Haynes, H.D.

    1989-01-01

    Motor current signature analysis (MCSA) is a powerful monitoring tool for motor-driven equipment that provides a nonintrusive means for detecting the presence of mechanical and electrical abnormalities in the motor and the driven equipment, including altered conditions in the process ''downstream'' of the motor-driven equipment. It was developed at the Oak Ridge National Laboratory as a means for determining the effects of aging and service wear systems, but it is applicable to a broad range of machinery. MCSA is based on the recognition that an electric motor (ac or dc) driving a mechanical load acts as an efficient and permanently available transducer by sensing mechanical load variations, large and small, long-term and rapid, and converting them into variations in the induced current generated in the motor windings. These motor current variations are carried by the electrical cables processes as desired. Motor current signatures, obtained in both time and over time to provide early indication of degradation. Successful applications of MCSA technology (patent applied for) include not only motor-operated valves but also pumps of various designs, blowers, and air conditioning systems. Examples are presented briefly, and speculation regarding the applicability of MCSA to a broader range of equipment monitoring and production line testing is also given. 1 ref., 13 figs

  17. Research on the induction motor current signature for centrifugal pump at cavitation condition

    2015-11-01

    Full Text Available Cavitation is a major undesirable phenomenon for centrifugal pump because it can cause hydraulic performance deterioration, pump damage by pitting and material erosion, and structural vibration and noise. Cavitation can appear within the entire range of the operating conditions; therefore, it must be prevented by all means. Sensorless monitoring technology based on motor current signature analysis is non-intrusive and economic for monitoring motor-driven equipment. Thus, this technology is suitable for centrifugal pump systems. The motor current signature for centrifugal pump load at the cavitation condition is the basis of this technology. However, systematic research is lacking on sensorless monitoring technology based on motor current signature. As a result, the tentative exploration for motor current signature at cavitation load was conducted in this study. The results show that the stator current is still a sinusoidal alternating current strictly to the law of sine. Moreover, the root mean square of the current fluctuates because of different flow regimes in the cavitation progress and decreases because vapor density is smaller than water density when cavitation is fully formed. For the stator current spectrum, the noise level, noise distribution, rotation speed, and vane pass frequency components show features in the cavitation process. These indicator indexes change according to the stage of cavitation development. Thus, the motor current signature analysis is found to be a feasible and cost-effective method for the stages of cavitation condition.

    Full Text Available The aim of the article is to reveal the influence of geo-economic transformations on the trends in international migration of human resources as an element of the resource potential of countries and regions. The current state of geo-economic transformations is analyzed, and their influence on the processes of international migration of human resources is revealed. The relevance of analyzing international movement of human resources, not labor ones, in building the geo-economic strategy of a country or a regional grouping is justified. The connection between the international migration of human resources and the trends in development of individual countries and regions (oil exporting countries, newly industrialized countries and least developed agrarian countries is determined, the general patterns of migration flows in these countries are described. Furthermore, the topical issues in studying international migration of human resources in the context of the directions of geo-economics identified by scientists are formulated. It is determined that the regional migration policy should contribute to maximizing the benefits of migration of human resources for the development of the region and the use of immigrants in the countries of the region as an economic resource that becomes strategically important under conditions of geo-economic transformations.

    Wall conditioning will be required in ITER to control fuel and impurity recycling, as well as tritium (T) inventory. Analysis of conditioning cycle on the JET, with its ITER-Like Wall is presented, evidencing reduced need for wall cleaning in ITER compared to JET–CFC. Using a novel 2D multi-fluid model, current density during Glow Discharge Conditioning (GDC) on the in-vessel plasma-facing components (PFC) of ITER is predicted to approach the simple expectation of total anode current divided by wall surface area. Baking of the divertor to 350 °C should desorb the majority of the co-deposited T. ITER foresees the use of low temperature plasma based techniques compatible with the permanent toroidal magnetic field, such as Ion (ICWC) or Electron Cyclotron Wall Conditioning (ECWC), for tritium removal between ITER plasma pulses. Extrapolation of JET ICWC results to ITER indicates removal comparable to estimated T-retention in nominal ITER D:T shots, whereas GDC may be unattractive for that purpose.

    Full Text Available It has been more than 50 years since the idea to construct the bridge of Sunda Strait was inspirited by Prof. Sedyatmo. This issued is very important due to accelerate the economic growth between Sumatera Island and Java Island which is known as the densest population in the Indonesia. However, until today the bridge is still not construct yet because the high budget and the lack of technical data are still being problems. One of the most important data is current condition along the Sunda Strait. Unfortunately, no one has been clearly studied about current condition along Sunda Strait. Therefore, the information about current condition would be completed to fulfil the lack of data and information. The RV Geomarine I, as a research vessel conducted the survey in October 2012 that one of the objectives is to get the impression about the current condition around the bridge plan. Attaching echo sounder of bathy 1500 to get the depth profile and applied the RD Instrument ADCP Mobile Workhorse Monitor 300 kHz to collect the real current data and analyze the current using numerical model by Mike 21 were carried out to describe the condition of the current around the bridge proposed. In addition, the detail flexible mesh of hydrodynamic model is applied along bridge plan to analyse the current condition that caused by seafloor morphology. Based on the ADCP data it would be seen that the highest velocity record of the current occurs at October 18th 2012 at line 19 with the value 2.63 m/sec. Nevertheless, the numerical model shown the highest current velocity occurs around the northwest of Sangiang Island where the speed attains more than 4.59 m/sec.

    Unemployment and health selection in diverging economic conditions: Compositional changes? Evidence from 28 european countries. People with ill health tend to be overrepresented among the unemployment population. The relationship between health and unemployment might, however, be sensitive to the overall economic condition. Specifically, the health composition of the unemployment population could change dramatically when the economy takes a turn for the worse. Using EU-SILC cross sectional data from 2007 (pre-crisis) and 2011 (during crisis) and linear regression models, this paper investigates the relationship between health and unemployment probabilities under differing economic conditions in 28 European countries. The countries are classified according to (i) the level of and (ii) increase in unemployment rate (i.e. >10 percent and doubling of unemployment rate = crisis country). Firstly, the unemployment likelihood for people with ill health is remarkably stable over time in Europe: the coefficients are very similar in pre-crisis and crisis years. Secondly, people with ill health have experienced unemployment to a lesser extent than those with good health status in the crisis year (when we pool the data and compare 2007 and 2011), but only in the countries with a high and rising unemployment rate. The health composition of the unemployment population changes significantly for the better, but only in those European countries that have been severely hit by the current economic crisis.

    2013-01-01

    The National Wildlife Refuge System Improvement Act of 1997 requires all units of the National Wildlife Refuge System to be managed under a Comprehensive Conservation Plan (CCP). The CCP must describe the desired future conditions of a refuge and provide long-range guidance and management direction to achieve refuge purposes. Charles M. Russell (CMR) National Wildlife Refuge, located in north-central Montana, is in the process of developing a range of management goals, objectives, and strategies for the CCP. The CCP for the Refuge must contain an analysis of expected effects associated with current and proposed refuge-management strategies. For refuge CCP planning, an economic analysis provides a means of estimating how current management (No Action Alternative) and proposed management activities (Alternatives) affect the local economy. This type of analysis provides two critical pieces of information: (1) it illustrates a refuge’s contribution to the local community; and (2) it can help in determining whether economic effects are or are not a real concern in choosing among management alternatives. It is important to note that the economic value of a refuge encompasses more than just the impacts on the regional economy. Refuges also provide substantial nonmarket values (values for items not exchanged in established markets) such as maintaining endangered species, preserving wetlands, educating future generations, and adding stability to the ecosystem (Carver and Caudill, 2007). However, quantifying these types of nonmarket values is beyond the scope of this study. This report first presents a description of the local community and economy near the Refuge. Next, the methods used to conduct a regional economic impact analysis are described. An analysis of the final CCP management strategies that could affect stakeholders and residents and the local economy is then presented. The refuge management activities of economic concern in this analysis are:

    In developing countries, where growth expectations are high, least-cost environmental policies are crucial since they can reduce the conflict between economic growth and the environment. In view of this, policymakers in these economies must be very aware of the relationship between economic and environmental issues to offer policy initiatives which can increase efficiency and improve equity. The authors provide a comprehensive analysis of topics varying from the general problems of growth and conservation to specific applications such as; pollution costs, environmental taxation, deforestation and climate change. This volume also offers policymakers a comprehensive view of the challenges they face, and the legacies they leave, in order to convert environmental policy making into an actual programme of welfare improvement.

  6. Toroidal current asymmetry and boundary conditions in disruptions

    Science.gov (United States)

    Strauss, Henry

    2014-10-01

    It was discovered on JET that disruptions were accompanied by toroidal asymmetry of the plasma current. The toroidal current asymmetry ΔIϕ is proportional to the vertical current moment ΔMIZ , with positive sign for an upward vertical displacement event (VDE) and negative sign for a downward VDE. It was claimed that this could only be explained by Hiro current. It is shown that instead it is essentially a kinematic effect produced by the VDE displacement of a 3D magnetic perturbation. This is verified by M3D simulations. The simulation results do not require penetration of plasma into the boundary, as in the Hiro current model. It is shown that the normal velocity perpendicular to the magnetic field vanishes at the wall, in the small Larmor radius limit of electromagnetic sheath boundary conditions. Plasma is absorbed into the wall only via the parallel velocity, which is small, penetrates only an infinitesimal distance into the wall, and does not affect forces exerted by the plasma on the wall. Supported by USDOE and ITER.

    One of the main questions in electricity market deregulation is the aptitude of private capital for investments in power generation. This is especially important in Brazil, whose load has a strong growth trend ({approx}6% per year). Thermopower is an attractive alternative for expanding generation, as it is complementary in many aspects to hydropower, which supplies most Brazil's power at a very low price most of the time, but makes the system vulnerable to seasonal water variations. This paper studies the competitiveness of thermopower generation in Brazil under current regulations; assesses under the real options theory approach the conditions for investments in thermopower generation, and finally presents and discusses a hydropower generation schedule model.

  9. PERSPECTIVES OF INFLATION TARGETING, IN THE CURRENT ECONOMIC CONTEXT

    2015-04-01

    Full Text Available In the context of economic crisis, monetary policy makers are facing a number of challenges, including the selection and implementation of the best monetary policy. In this paper, we want to see if inflation targeting is or is not a solution to exit the economic crisis. If the answer is positive, then what would be the optimal level of inflation? Many central banks target an inflation rate of 2%. In this paper we intend to show that, in certain circumstances, a very low level of inflation can significantly reduce the stabilizing effects of monetary policy. A slightly higher value of inflation targeting would reduce the constraints on monetary policy, caused by the appearance of liquidity trap. The risk for the interest rates of monetary policy to achieve zero level is related to the central banks’ choise of the appropriate inflation target. We believe that an increase in the inflation target of 2% to 4% would ease monetary policy constraints arising from the liquidity trap problem. If inflation targeting is not a solution to exit the crisis, then are there other strategies that would be a better alternative? Following this analysis, no obvious alternatives were identified, so far, there is no clear reason for that to abandon inflation targeting.

  10. Flexicurity in the Current Economic and Social Context

    Directory of Open Access Journals (Sweden)

    Georgeta Modiga

    2015-05-01

    Full Text Available The flexicurity concept - an abbreviation between flexibility and security - appeared in the early 90s, being used for the first time by the Danish Prime Minister Poul Nyrum Rasmussen. The concept refers to a social state model that promotes a pro-active policy in the labour domain and the access to employment. Flexicurity can be defined as a strategy integrated by the simultaneous consolidation of flexibility and security on the labour market. According to the definition given by the European Commission, which establishes the guidelines and “paths” typical for the Member States in order to develop their own strategies in the field, flexicurity is an integrated strategy of simultaneous strengthening of flexibility and security on labour market. This concept arose as a result of socio-economic changes registered in the last decades in Europe: globalization and European integration, development of new technologies, the demographic aging of European society, the segmented development of labour markets.

    The National Wildlife Refuge System Improvement Act of 1997 requires all units of the National Wildlife Refuge System to be managed under a Comprehensive Conservation Plan. The Comprehensive Conservation Plan must describe the desired future conditions of a refuge and provide long-range guidance and management direction to achieve refuge purposes. The Rappahannock River Valley National Wildlife Refuge (refuge) is in the process of developing a range of management goals, objectives, and strategies for the Comprehensive Conservation Plan. The Comprehensive Conservation Plan for the refuge must contain an analysis of expected effects associated with current and proposed refuge management strategies. The purpose of this study was to assess the regional economic implications associated with draft Comprehensive Conservation Plan management strategies. Special interest groups and local residents often criticize a change in refuge management, especially if there is a perceived negative impact to the local economy. Having objective data on economic impacts may show that these fears are overstated. Quite often, the extent of economic benefits a refuge provides to a local community is not fully recognized, yet at the same time the effects of negative changes is overstated. Spending associated with refuge recreational activities, such as wildlife viewing and hunting, can generate considerable tourist activity for surrounding communities. Additionally, refuge personnel typically spend considerable amounts of money purchasing supplies in local stores, repairing equipment and purchasing fuel at the local service stations, and reside and spend their salaries in the local community. For refuge Comprehensive Conservation Plan planning, a regional economic assessment provides a means of estimating how current management (no action alternative) and proposed management activities (alternatives) could affect the local economy.

    Full Text Available Accountancy organizations, regulatory bodies, standard setters, and other international organizations have developed guidance, articles, frameworks and resources on issues related to the global financial crisis. Now there is a clear and widely accepted need for more rigorous governance over companies´ systems of internal control. Historically there exist many different activities aiming to support effective enterprise governance (legislative acts, best practices, standards, frameworks. But all these activities may have reinforced the already-existing focus on enterprise governance, but they did not necessarily bring clarity to the topic. Therefore we can currently notice some changes aiming to improve the adoption and adaptation of best practices and standards within the area of enterprise governance. The paper discusses the changes in the Enterprise Governance of IT/IS, audit/assurance evolution, and intended Cobit improvements.

    This report reviews recent DSM shareholder incentive designs and performance at 10 US utilities identifies opportunities for regulators to improve the design of DSM shareholder incentive mechanisms to increase the procurement of cost-effective DSM resources. We develop six recommendations: (1) apply shared-savings incentives to DSM resource programs; (2) use markup incentives for individual programs only when net benefits are difficult to measure, but are known to be positive; (3) set expected incentive payments based on covering a utility's open-quotes hidden costs,close quotes which include some transitional management and risk-adjusted opportunity costs; (4) use higher marginal incentives rates than are currently found in practice, but limit total incentive payments by adding a fixed charge; (5) mitigate risks to regulators and utilities by lowering marginal incentive rates at high and low performance levels; and (6) use an aggregate incentive mechanism for all DSM resource programs, with limited exceptions (e.g., information programs where markups are more appropriate)

    Full Text Available Abstract. Any management decision has a direct monetary impact on the structure uses and sources of cash. Cash Management aims to permanently maintain a balance between inflows and outflows of cash and cash to predict the impact of any operational decisions that could affect these flows. The success of any business requires good management of all these flows. The principle of this approach is relatively simple: using a minimum of ores to obtain maximum performance in a given period. Cash management is an extremely complex issue, and balancing receipts and payments flow is a constant struggle for survival of firms. In It work we will focus on how they are oriented in a going concern basis, cash inflows and financing needs of current operations. Managers should understand and know the specific movements of cash within the business system, driven daily decisions on operating, investing or financing, and a variety of external circumstances which affect the company. Such decisions and events can affect the company's ability to pay its obligations to obtain credit from suppliers, banks or credit institutions and to maintain an operational level in line with the company's products and services through investments.

  1. Condition monitoring and thermo economic optimization of operation for a hybrid plant using artificial neural networks

    2008-05-15

    The project aim is to model the hybrid plant at Vaesthamnsverket in Helsingborg using artificial neural networks (ANN) and integrating the ANN models, for online condition monitoring and thermo economic optimization, on site. The definition of a hybrid plant is that it uses more than one fuel, in this case a natural gas fuelled gas turbine with heat recovery steam generator (HRSG) and a biomass fuelled steam boiler with steam turbine. The thermo economic optimization takes into account current electricity prices, taxes, fuel prices etc. and calculates the current production cost along with the 'predicted' production cost. The tool also has a built in feature of predicting when a compressor wash is economically beneficial. The user interface is developed together with co-workers at Vaesthamnsverket to ensure its usefulness. The user interface includes functions for warnings and alarms when possible deviations in operation occur and also includes a feature for plotting parameter trends (both measured and predicted values) in selected time intervals. The target group is the plant owners and the original equipment manufacturers (OEM). The power plant owners want to acquire a product for condition monitoring and thermo economic optimization of e.g. maintenance. The OEMs main interest lies in investigating the possibilities of delivering ANN models, for condition monitoring, along with their new gas turbines. The project has been carried out at Lund University, Department of Energy Sciences, with support from Vaesthamnsverket AB and Siemens Industrial Turbomachinery AB. Vaesthamnsverket has contributed with operational data from the plant as well as support in plant related questions. They have also been involved in the implementation of the ANN models in their computer system and the development of the user interface. Siemens have contributed with expert knowledge about their SGT800 gas turbine. The implementation of the ANN models, and the accompanying user

    Full Text Available The world economic environment of the turn of the century produced many new challenges to civil aviation in expectation of a continued growth in the transportation of passengers and cargo. To meet this growing demand, it will be necessary to increase the fleet and to modernise infrastructure – a process hampered by finances and capacity constraints.Such constraints are especially pressing with regard to the acquisition of new types of large aircraft such as the Airbus A380 and the Boeing 787 and 747-8. Future dominance of the market is, however, difficult to predict, as this will be the outcome of a combination of uncertain parameters.

    To assess the economic impact of the duration of antidepressant drug treatment in a real-life setting. A historical fixed cohort study included 27 917 patients aged 18 and over with a new antidepressant treatment registered in the national insurance database. The economic impact concerned healthcare expenditure in the first 3 months after treatment discontinuation. Generalized linear models were used to compare two groups of treatment duration: adjustment for care costs before and during treatment episode, gender, age, chronic diseases, welfare and prescriber specialty, total healthcare costs (in log) [-0.06 (-0.14;0.01) P = 0.11] and psychiatric care costs (in square root) [-0.08 (-0.41;0.25) P = 0.6] were similar in both groups. Non-psychiatric care costs were significantly lower in the 'long treatment duration' group compared with the 'short treatment duration' group [-11.4 (-15.8; -7.0) P costs over the antidepressant treatment episode were larger in the 'long treatment duration' group compared with the 'short treatment duration' group. With regard to healthcare costs and global health, antidepressant drug treatments of short duration appear less effective than treatment of recommended duration. © 2012 John Wiley & Sons A/S.

    Full Text Available Global economic crisis has, following financial crisis, hit real sector, and as after effect, large number, mostly developed countries in the world are in recession. Serbian industry is also influenced by global economic crisis. Outer debt is significantly and constantly increasing since beginning of transition process. Main cause to it is rather large disproportion between import and export. Trends in structure of outer debt indicate on notable decrease of national debt on account to private one, during whole transition period. On short term there is no significant risk for country on account of outer debt, but for long term elimination of this risk, it is necessary to considerably increase total export. Former policies should be linked to unconventional employment initiatives, as for new labour, as for redundant ones from restructuring economy branches. State has prominent role in transition process, by helping market exhibit its functions through physical and institutional infrastructure, as well trough public sector, removing most of the market obstacles, and stimulating technical-technological development and education.

It can be proven by the fact that economic relationship between this two countries are transferring from the national trade model to various models such as border trade, agency trade, the illicit trade and investment aid. In this progress, North Korea rely China more than in 1990. But after 1992, the economic relationship is falling from the political priority as before, blind support and assistance based on the nature of the economic benefits to the rapid changes in relationship. This thesis reviewed economic relations in the world environment which has changed. First it analyzed the national economy and trade policies adopted in the current situation of two countries, and on this basis, it looked forward to the economic relationship between the two countries, and point out the measures regarding the relationship between two countries.

    Previous research has found a positive short-term relationship between the 2008 collapse and hypertension in Icelandic males. With Iceland's economy experiencing a phase of economic recovery, an opportunity to pursue a longer-term analysis of the collapse has emerged. Using data from a nationally representative sample, fixed-effect estimations and mediation analyses were performed to explore the relationship between the Icelandic economic collapse in 2008 and the longer-term impact on hypertension and cardiovascular health. A sensitivity analysis was carried out with pooled logit models estimated as well as an alternative dependent variable. Our attrition analysis revealed that results for cardiovascular diseases were affected by attrition, but not results from estimations on the relationship between the economic crisis and hypertension. When compared to the boom year 2007, our results point to an increased probability of Icelandic women having hypertension in the year 2012, when the Icelandic economy had recovered substantially from the economic collapse in 2008. This represents a deviation from pre-crisis trends, thus suggesting a true economic-recovery impact on hypertension.

    Insight into the total economic burden of diabetes mellitus (DM) is essential for decision makers and payers. Currently available estimates for the Netherlands only include part of the total burden or are no longer up-to-date. Therefore, this study aimed to determine the current total economic burden of DM and its complications in the Netherlands, by including all the relevant cost components. The study combined a systematic literature review to identify all relevant published information and a targeted review to identify relevant information in the grey literature. The identified evidence was then combined to estimate the current total economic burden. In 2016, there were an estimated 1.1 million DM patients in the Netherlands, of whom approximately 10% had type 1 and 90% had type 2 DM. The estimated current total economic burden of DM was € 6.8 billion in 2016. Healthcare costs (excluding costs of complications) were € 1.6 billion, direct costs of complications were € 1.3 billion and indirect costs due to productivity losses, welfare payments and complications were € 4.0 billion. DM and its complications pose a substantial economic burden to the Netherlands, which is expected to rise due to changing demographics and lifestyle. Indirect costs, such as welfare payments, accounted for a large portion of the current total economic burden of DM, while these cost components are often not included in cost estimations. Publicly available data for key cost drivers such as complications were scarce.

  17. Intergenerational aspects of government policy under changing demographic and economic conditions.

    Science.gov (United States)

    Boskin, M J

    1987-07-01

    Changing demographic and economic conditions in the US require that attention be given to some of the intergenerational equity features of government policy. In particular, social insurance programs and public debt leave public liabilities to future generations. Taken in the aggregate, the effects of rapidly rising public debt and especially social insurance programs are transferring substantial amounts of resources from younger working generations to the expanding generation of retirees. The most crucial element in evaluating the desirability of intergenerational wealth distribution in the long run is the rate of economic growth. A society's monetary, fiscal, tax, and regulatory policies can be more or less conducive to the generation of capital formation, technical change, and economic growth. Policies that influence growth and interest rates will combine with the national deficit to determine how rapidly the debt grows or shrinks. Present accounting procedures are insufficient to provide quantitative answers to the question of what is the impact of a given program on the age-specific distributions of resources. It is important to reconsider the desirability and efficiency of intergenerational redistributions of wealth in the US. It is likely that current policies are not in line with the principles of efficiency, equity, target effectiveness, and cost effectiveness.

    Current evidence suggests that chlamydia screening programmes can be cost-effective, conditional on assumptions within mathematical models. We explored differences in cost estimates used in published economic evaluations of chlamydia screening from seven countries (four papers each from UK and the Netherlands, two each from Sweden and Australia, and one each from Ireland, Canada and Denmark). From these studies, we extracted management cost estimates for seven major chlamydia sequelae. In order to compare the influence of different sequelae considered in each paper and their corresponding management costs on the total cost per case of untreated chlamydia, we applied reported unit sequelae management costs considered in each paper to a set of untreated infection to sequela progression probabilities. All costs were adjusted to 2013/2014 Great British Pound (GBP) values. Sequelae management costs ranged from £171 to £3635 (pelvic inflammatory disease); £953 to £3615 (ectopic pregnancy); £546 to £6752 (tubal factor infertility); £159 to £3341 (chronic pelvic pain); £22 to £1008 (epididymitis); £11 to £1459 (neonatal conjunctivitis) and £433 to £3992 (neonatal pneumonia). Total cost of sequelae per case of untreated chlamydia ranged from £37 to £412. There was substantial variation in cost per case of chlamydia sequelae used in published chlamydia screening economic evaluations, which likely arose from different assumptions about disease management pathways and the country perspectives taken. In light of this, when interpreting these studies, the reader should be satisfied that the cost estimates used sufficiently reflect the perspective taken and current disease management for their respective context.

    Full Text Available The Great Recession was associated with reduced fertility in the United States. Many questions about the dynamics underlying this reduction remain unanswered, however, including whether reduced fertility rates were driven by decreases in intended or unplanned pregnancies. Using restricted data from the 2006–2010 National Survey of Family Growth (N = 4,630, we exploit variation in state economic indicators to assess the impact of economic conditions on the likelihood of an intended pregnancy, an unplanned pregnancy, or no pregnancy for adult women without a college education. We focus on variations by partnership and marital status. Overall, we find that worse economic conditions were predictive of a lower risk of unplanned pregnancy. Women's odds of intended pregnancy did not, however, respond uniformly to economic conditions but varied by marital status. When economic conditions were poor, married women had lower odds of intended pregnancy, whereas cohabiting women had greater odds of intended pregnancy.

  5. How can we improve socio-economic condition of women?

    Science.gov (United States)

    Mohapatra, P C; Pattanaik, B E

    Aspects of discrimination against women in India are summarized, a case study of a rural district in Orissa is presented, and the article follows with a suggested 3-part strategy of education, employment and appropriate technology. The economic role played by women is difficult to quantitate because of their lifestyle that combines domestic work and unpaid family or low-paid outside farm or cottage industry labor. Besides these tasks, women usually care for dairy animals, and carry water and firewood. Discrimination against women in this system is evident, however, from some available statistics. 46% of women, as opposed to 20% of men, work as agricultural laborers. Women are denied education because they are not expected to do responsible work, then they are denied employment because they are not educated. Their work is counted as worth only half that of men, and based on this assumption, they are paid less then men. The male heads of 124 households in 7 villages in the Orissa area were interviewed to study labor participation of household members. 89% of the people worked in agriculture, 94% in rice paddy and 6% in oilseed or pulses for cash crops. The average farm size was 2.29 acres. Female literacy had risen to 14.3% from 1% 10 years before. Women usually worked in transplantation, weeding, harvesting and threshing, but also in heavier farm labor, construction of roads and buildings, quarrying and forestry. In this poor, hilly region, the custom of purdah was not practiced to the extent of keeping women from doing day labor outside the home. The authors' suggested strategy for women's development included appropriate technology such as the Gobar methane gas plant, provision of credit for women's industries, retention of girls in school and literacy programs for girls and women, and higher wages for women.

    2014-05-01

    The demand for economic models that evaluate cancer treatments is increasing, as healthcare decision makers struggle for ways to manage their budgets while providing the best care possible to patients with cancer. Yet, after nearly 2 decades of cultivating and refining techniques for modeling the cost-effectiveness and budget impact of cancer therapies, serious methodologic and policy challenges have emerged that question the adequacy of economic modeling as a sound decision-making tool in oncology. We sought to explore some of the contentious issues associated with the development and use of oncology economic models as informative tools in current healthcare decision-making. Our objective was to draw attention to these complex pharmacoeconomic concerns and to promote discussion within the oncology and health economics research communities. Using our combined expertise in health economics research and economic modeling, we structured our inquiry around the following 4 questions: (1) Are economic models adequately addressing questions relevant to oncology decision makers; (2) What are the methodologic limitations of oncology economic models; (3) What guidelines are followed for developing oncology economic models; and (4) Is the evolution of oncology economic modeling keeping pace with treatment innovation? Within the context of each of these questions, we discuss issues related to the technical limitations of oncology modeling, the availability of adequate data for developing models, and the problems with how modeling analyses and results are presented and interpreted. There is general acceptance that economic models are good, essential tools for decision-making, but the practice of oncology and its rapidly evolving technologies present unique challenges that make assessing and demonstrating value especially complex. There is wide latitude for improvement in oncology modeling methodologies and how model results are presented and interpreted. Complex technical and

    For randomly selected 50 villages in Bangladesh, an interview survey with a structured questionnaire was conducted to reveal their perception on the environmental, health and economic conditions at present and for the past 10-year change. The eight following items were analyzed in this paper: air pollution and water pollution, which represent environmental conditions with close relation to health conditions, soil degradation and deforestation, which represent environmental conditions with close relation to economic conditions, epidemic diseases and malnutrition, which represent health conditions, and poverty and jobless, which represent economic conditions. Among the 50 villages, deforestation was most frequently perceived serious at present and worsened in the past 10 years. Of the remaining seven items, those related to economic conditions were more seriously perceived than those related to health and environmental conditions. As revealed by the cluster analysis for the inter-item relations, epidemic diseases, which formed the same cluster with the environmental items, were recognized less serious whereas malnutrition, which formed the same cluster with the economic items, was recognized more serious. These findings are useful not only for rural development programs but also for mitigation programs toward health and environmental hazards in Bangladesh.

    To assess the association of parental education, childhood living conditions and adversities with daily smoking in early adulthood and to analyse the effect of the respondent's own education, main economic activity, and current family structure on these associations. The study is based on a representative two-stage cluster sample (N = 1894, participation rate 79%) of young adults aged 18-29, in 2000, in Finland. The outcome measure is daily smoking. Parental smoking and the respondent's own education had the strongest effects on daily smoking. If both parents of the respondent were smokers, then the respondent was most likely to be a smoker too (for men OR (odds ratio) = 3.01, for women OR = 2.41 after all adjustments). Young adults in the lowest educational category had a much higher risk of daily smoking than those in the highest category (OR = 5.88 for women, 4.48 for men). For women parental divorce (OR = 2.31) and current family structure also determined daily smoking. Parental education had a strong gradient in daily smoking and the effect appeared to be mediated largely by the respondent's own educational level. Childhood living conditions are strong determinants of daily smoking. Much of their influence seems to be mediated through current living conditions, which are also determined by childhood conditions. Determinants of smoking behaviour are developed throughout the life course. The findings stress the importance of the respondent's education and parental smoking as determinants of smoking behaviour. Our results support the notion that intervention on smoking initiation and cessation should be considered throughout the life course. Parental involvement in fostering non-smoking would be important.

    Turbidity currents pose a hazard to seafloor infrastructure, deliver organic carbon and nutrients to deep-sea communities, and form economically important deposits. Thus, determining the tempo of turbidity current activity and whether different triggers result in different flow modes is important. Identification of specific triggers is challenging, however, because most studies of turbidity currents are based on their deposits. New direct monitoring of flows and environmental conditions provides the necessary temporal constraints to identify triggering mechanisms. The Coordinated Canyon Experiment (CCE) in Monterey Canyon, offshore California is the most ambitious attempt yet to measure turbidity flows and their triggers. The CCE provides precise constraint on flow timing, initiation, and potential triggers based on measurements at 7 different instrumented moorings and 2 metocean buoys. Fifteen turbidity flows were measured in 18 months; with recorded velocities >8 m/s and run-outs of up to 50 km. Presence of live estuarine foraminifera within moored sediment traps suggests that that flows originated in water depths of Turbidity currents are thought to be triggered by processes including earthquakes, river floods and storm waves. Here we analyse seismicity, local river discharge, internal tides, wave height, direction and period data. We identify no clear control of any of these individual variables on flow timing. None of the recorded earthquakes (

    A submersible particle image velocimetry (PIV) system was used to study the wake of a horizontal axis marine current turbine. The turbine was tested in a large tow tank facility at the United States Naval Academy. The turbine is a 1/25th scale model of the U.S. National Renewable Energy Laboratory's Reference Model 1 (RM1) tidal turbine. It is a two-bladed turbine measuring 0.8 m in diameter and featuring a NACA 63-618 airfoil cross section. Separate wind tunnel testing has shown the foil section used on the turbine to be Reynolds number independent with respect to lift at the experimental parameters of tow carriage speed (Utow = 1 . 68 m/s) and tip speed ratio (TSR = 7). The wake survey was conducted over an area extending 0.25D forward of the turbine tip path to 2.0D aft, and to a depth of 1.0D beneath the turbine output shaft in the streamwise plane. Each field of view was approximately 30 cm by 30 cm, and each overlapped the adjacent fields of view by 5 cm. The entire flow field was then reconstructed into a single field of investigation. Results include streamwise and vertical ensemble average velocity fields averaged over approximately 1,000 realizations, as well as higher-order statistics. Turbine tip vortex centers were identified and plotted showing increasing aperiodicity with wake age. keywords: horizontal axis marine current turbine, particle image velocimetry, towing tank, wake survey

    Full Text Available Stingless bees (kelulut keeping is now a trend in Malaysia. However, since demand for the source of colony in log is increasing, the log price is rapidly increasing. But, there is no data reported on the economic viability of meliponiculture in the current market price. Thus, the objective of this study is to clarify the economic viability of investment in meliponiculture in the current market price by engineering economic perspective. Investment in meliponiculture was analysed using Equivalent Annual Uniform Cost (EAUC, Internal Rate of Return (IRR and Breakeven Analysis. A small start-up with 30 units of logs or hives was considered in the analysis. All raw data was acquainted from current Malaysian market price, but only revenue from honey was considered. It was found that EAUC indicated that the annual worth of the log system is 23% better than the hive system. However, IRR calculation indicated that both the log and the hive systems offer margin exceeding 55% which is a very good return in general investment. In addition, it was also found that the log system had breakeven after 8th month, whereas the hive was 13th month. Better economic value could be obtained if revenue from by-products are considered. Thus, it can be concluded that meliponiculture is still very economically viable in Malaysia market trend, and the hive systems could be a better choice if splitting colony, maintenance, safety and aesthetics points of view are considered.

    Full Text Available This article focuses on development of Russian-Lithuanian economic ties. The research and practical significance of this study lies in the identification of the sources of modern Russian-Lithuanian economic cooperation and the prospects of future mutually beneficial economic relations. The first attempt at establishing economic relations was made in 1919. However, young Lithuanian Republic gravitated towards the West, severing ties with the Russian market. However, the initiatives of Lithuanian authorities did not result in successful state building, and the economic situation remained unchanged. The USSR leadership made an effort to improve the living conditions in post-war Lithuania. There were some mistakes made in the relations with the local population that resulted in Lithuanians’ resistance to sovietisation. However, in the conditions of post-war restoration of national economy and acute deficit of material and human resources, the Soviet leadership managed not only to reform and develop a socialistic economy in Lithuania but also to turn it into an industrial republic with developed agriculture and modern manufacturing facilities, whose major industries manufactured products used in nuclear and space technologies, aviation and navigation. The research shows that the post-Soviet period led to a dramatic change in Russian-Lithuanian economic relations; however, these relations retained potential for future development.

    A virtually complete description of the topology of stationary incompressible Euler flows and the magnetic field satisfying the magnetostatic equation is given by a theorem due to Arnol'd. We apply this theorem to describe the topology of stationary states of plasmas with significant fluid flow, obeying the Hall magnetohydrodynamics model equations. In the context of the integrability (nonchaotic topology) of the magnetic and velocity fields, we discuss the validity of conditions analogous to that of Greene and Johnson, which, in the case of magnetostatic equations, states that the line integral ∫dl/B is the same for each closed magnetic field line on a given magnetic surface. We also show how this property follows from the existence of a continuous volume-preserving symmetry of the magnetic field

    2013-05-01

    Full Text Available The current economic environment is characterized by uncertainties related to price volatility, difficulties in the valuation of financial instruments, as well as of assets and liabilities in general. More and more companies face liquidity issues that could even threaten their existence. Under these circumstances, saving such companies becomes a major concern for the ones directly interested, “survival” being the term most used in the current state of the world’s economy. In the context of this economic turmoil at international level, the main stakeholders and the accountants professionals find themselves in the position of revising their procedures, objectives, strategies, but also their behaviour, their attitude in general, in order to limit or even eliminate the negative consequences of the financial crisis. From our perspective, the communication among company, stakeholders, and auditors represents the fundament of a successful business strategy. However, communication difficulties could be encountered, especially under conditions of uncertainty and crisis. The present article intends to identify the opportunities and threats generated by the economic crisis and to analyze the information flows among company, stakeholders and accountants professionals under circumstances in which the going concern assumption is threatened. Our paper emphasizes the importance of communication among company, stakeholders, and auditors in saving the firms affected by the economic crisis.

  19. Experimental Determination of Bed Conditions in Concentrated Pyroclastic Density Currents

    Winner, A.; Ferrier, K.; Dufek, J.

    2016-12-01

    Pyroclastic density currents (PDCs) are ground-hugging mixtures of hot gas and rock that can reach temperatures > 800 oC and speeds of 200 m/s. These flows are capable of eroding and entraining the underlying bed material into the flow, which can strongly influence flow momentum, runout distance, and hazards associated with PDCs. However, the mechanism of erosion remains poorly constrained, with proposed mechanisms including under-pressure following the head of the fluidized current, force chain enhanced stresses at the bed, and discrete particle impacts and friction. The interactions between PDCs and the bed have been difficult to observe in the field, as their infrequent occurrence, opacity, and hostile environment make real-time measurement difficult. This study is aimed at obtaining a better understanding of the interactions between PDCs and the bed through a quantitative analysis of bed forces. Our experimental apparatus consists of a rotating cylindrical flume of radius 22 cm, within which gas-rich granular material flows along the interior of the cylinder as it rotates. By using a rotating cylinder, we are able to simulate long-duration flows, allowing us to observe impact forces at the bed over timescales comparable to the flow duration of natural PDCs. To measure the distribution and evolution of forces imparted by the flow on the bed, we constructed a cylindrical insert with a non-erodible bed in which we embedded force sensor arrays parallel and perpendicular to the direction of flow. To measure the forces felt by the particles in the flow, we added "smart particles" 25 to 50 mm in diameter to the flow. Each smart particle contains a three-axis accelerometer and a micro SD card enclosed in a spherical plastic casing, and possesses a density similar to that of the pumice in the experimental flow. Each smart particle also contains a three-axis magnetometer which permits its location to be tracked by means of a unique applied magnetic field. Ultimately

    Adverse socioeconomic conditions in childhood have been previously linked with high risk of various health conditions. However, the association with future physical function has been less studied. Hand grip strength and chair-rising time are objective measures of physical capability indicating current and future health outcomes. The aim of this study was to test the hypothesis that perceived socio-economic status in childhood is related to current measures of physical function, among Israeli participants of the Survey of Health, Ageing and Retirement in Europe project. The study included 2300 participants aged 50 years or older (mean age 68 ± 10; 56 % women). Generalized linear regression models were used to examine the associations of childhood wealth and number of books in residence with grip strength and time to complete five rises from a chair. Logistic regression models were used to assess the relationships between the early life conditions and the ability to perform the physical tests. Adjustment was made for current income or household wealth, and for demographic, anthropometric, health, and life-style measures. Being wealthy and having a large number of books at home in childhood was associated with a stronger hand grip and a better chair-rise test performance. These associations were more robust in women compared to men, and persisted after adjustment for potential covariates. In addition, childhood wealth and number of books were associated with lower risk of being unable to perform the tests. Thus, early-life programming may contribute to physical function indicators in mid- and late-life.

    Understanding mothers' economic conditions and postpartum depression (PPD) is important for determining how they will take care of themselves and their infants during the postnatal period, especially for low-income families. This study examined the relationship between economic conditions and PPD to elucidate the effect of economic contraction on PPD. Our population-based nationwide study used 2000-2013 the National Health Insurance Research Database of Taiwan. A total of 1240 newly diagnosed PPD patients were recruited. We used the database of the Directorate General of Budget, Accounting, and Statistics of Executive Yuan of Taiwan for national economic indicators. The correlation between economic indicators and PPD was examined. The PPD incidence was positively correlated with yearly unemployment rate, consumer price index, and gross domestic product. During the great recession of 2008-2009, PPD was positively correlated with inflation rate. Consumer price index had a positive correlation with PPD incidence per month when comparing PPD in 2010 with the economic indicators during the great recession. As this retrospective study evaluated macroeconomic indicators, it is unclear whether the macroeconomic indicators' effect on PPD totally reflects the effect of true personal economic status on PPD. There was a significant association between PPD and economic conditions. This study shows that mothers' familial environment plays an important role in the development of PPD. The impact of the worldwide economic downturn of the great recession on women is persistent. This useful finding may give health policy planners a hint of early discovering and dealing with PPD when worldwide economic downturn. Copyright © 2016 Elsevier B.V. All rights reserved.

    The Mid-Latitude zone can be broadly defined as part of the hemisphere between around 30° - 60° latitude. This zone is a home to over more than 50% of the world population and encompasses about 36 countries throughout the principal regions which host most of the global problems related to development and poverty. Mid-Latitude region and its ecotone demands in-depth analysis, however, latitudinal approach has not been widely recognized, considering that many of natural resources and environment indicators, as well as social and economic indicators are based on administrative basis or by country and regional boundaries. This study sets the land cover change and use stage based on environmental condition and economic development. Because various land cover and use among the regions, form vegetated parts of East Asia and Mediterranean to deserted parts of Central Asia, the forest area was varied between countries. In addition, some nations such as North Korea, Afghanistan, Pakistan showed decreasing trends in forest area whereas some nations showed increasing trends in forest area. The economic capacity for environmental activities and policies for restoration were different among countries. By adopting the standard from IMF or World Bank, developing and developed counties were classified. Based on the classification, this study suggested the land cover and use stages as degradation, restoration, and sustainability. As the degradation stage, the nations which had decreasing forest area with less environmental restoration capacity based on economic size were selected. As the restoration stage, the nation which had increasing forest area or restoration capacity were selected. In the case of the sustainability, the nation which had enough restoration capacity with increasing forest area or small ratio in forest area decreasing were selected. In reviewing some of the past and current major environmental challenges that regions of Mid-Latitudes are facing, grouping by

    2016-12-01

    Full Text Available This paper proposes a balanced current control strategy for the current source rectifier (CSR stage of an indirect matrix converter (IMC under unbalanced grid voltage conditions. If the three-phase grid connected to the voltage source inverter (VSI of the IMC has unbalanced voltage conditions, it affects the currents of the CSR stage and VSI stage, and the currents are distorted. Above all, the distorted currents of the CSR stage cause instability in the overall system, which can affect the life span of the system. Therefore, in this paper, a control strategy for balanced currents in the CSR stage is proposed. To achieve balanced currents in the CSR stage, the VSI stage should receive DC power without ripple components from the CSR stage. This is implemented by controlling the currents in the VSI stage. Therefore, the proposed control strategy decouples the positive and negative phase-sequence components existing in the unbalanced voltages and currents of the VSI stage. Using the proposed control strategy under unbalanced grid voltage conditions, the stability and life span of the overall system can be improved. The effectiveness of the proposed control strategy is verified by simulation and experimental results.

    Full Text Available according to the author, the lack of unified approaches to the calculation of financial indicators, the multiple interpretations of their meanings ​​and the imperfection of information support of financial analysis hamper the effectiveness of economic entities operating under market principles. The existing approach to determining the financial condition of an enterprise does not always give the required qualitative result of an evaluation of its financial and economic activities. While analyzing the financial status of economic entities, it would be useful to take into account their industry particularities, size and organizational structure, development strategy and competitiveness in the market for goods and services.

    Full Text Available Background: This study further develops Goldstein et al.'s (2013 analysis of the fertility response to the Great Recession in western economies. Objective: The purpose of this paper is to shed light on the fertility reaction to different indicators of the crisis. Beyond the structural labor market conditions, I investigate the dependence of fertility rates on economic policy uncertainty, government financial risk, and consumer confidence. Methods: Following Goldstein et al. (2013, I use log-log models to assess the elasticity of age-, parity-, and education-specific fertility rates to an array of indicators. Besides the inclusion of a wider set of explanatory variables, I include more recent data (2000−2013 and I enlarge the sample to 31 European countries plus the United States. Results: Fertility response to unemployment in some age- and parity-specific groups has been, in more recent years, larger than estimated by Goldstein et al. (2013. Female unemployment has also been significantly reducing fertility rates. Among uncertainty measures, the drop in consumer confidence is strongly related to fertility decline and in Southern European countries the fertility response to sovereign debt risk is comparable to that of unemployment. Economic policy uncertainty is negatively related to TFR even when controlling for unemployment. Conclusions: Theoretical and empirical investigation is needed to develop more tailored measures of economic and financial insecurity and their impact on birth rates. Contribution: The study shows the nonnegligible influence of economic and financial uncertainty on birth rates during the Great Recession in Western economies, over and above that of structural labor market conditions.

    Transition to adulthood has undoubtedly changed in the last few decades. For youth today, an important marker of adulthood is self-actualization in their professional career, and, consequently, also the achievement of stable financial conditions. Economic conditions of youth are greatly subject to fluctuations in the economy, and the subsequent governmental response. Using the Luxembourg Income Study, this work investigates the trends in income from work of young adults before and after the Great Recession of 2008 in five countries-US, UK, Norway, Germany, and Spain. The findings showed deterioration in economic conditions of young men, but with differences across countries. Young women suffered less from the crisis, and in some countries, their economic situation improved. The general negative trend was especially pronounced for those with high education, which is primarily because they stayed in education longer.

    Migraine is often perceived as a low-impact condition that imposes a limited burden to society and the health-care system. This study reviews the current understanding of the burden of migraine in the U.S., the history of economic understanding of migraine treatment and identifies emergent trends for future studies evaluating clinical and economic outcomes of migraine treatment. This study traced the history of economic articles published on migraine by performing a literature search using PubMed MEDLINE database and ancestral searches of relevant articles. The intention was not to provide an exhaustive review of every article or adjudicate between studies with different findings. Migraine affects millions of individuals worldwide, generally during the most productive years of a person's life. Studies show that migraineurs are underdiagnosed, undertreated, and experience substantial decreases in functioning and productivity, which in turn translates into diminished quality of life for individuals, and financial burdens to both health-care systems and employers. Economic evaluations of migraine therapies have evolved with new clinical developments beginning with cognitive-behavioral therapy, introduction of triptans, concern over medication overuse, and emergence of migraine prophylaxis. Now recent clinical studies suggest that migraine may be a progressive disease with cardiovascular, cerebrovascular, and long-term neurologic effects. Migraine imposes a substantial burden on patients, families, employers and societies. The economic standards by which migraine and treatment are evaluated have evolved in response to clinical developments. Emerging evidence suggests that migraine is a chronic and progressive disease. If confirmed, approaches to acute and prophylactic treatments and economic evaluations of migraine treatment may require major reconsideration.

    Exergo-economic analysis is an unique combination of exergy analysis and cost analysis conducted at the component level. In exergo-economic analysis, cost of each exergy stream is determined. Inlet and outlet exergy streams of the each component are associated to a monetary cost. This is essential to detect cost-ineffective processes and identify technical options which could improve the cost effectiveness of the overall energy system. In this study, exergo-economic analysis is applied to an aircraft turboprop engine. Analysis is based on experimental values at low torque condition (240 N m). Main components of investigated turboprop engine are the compressor, the combustor, the gas generator turbine, the free power turbine and the exhaust. Cost balance equations have been formed for all components individually and exergo-economic parameters including cost rates and unit exergy costs have been calculated for each component.

  13. THE ENTREPRENEURIAL START-UP PROCESS: THE ROLE OF SOCIAL CAPITAL AND THE SOCIAL ECONOMIC CONDITION

    Full Text Available Entrepreneurship is a complex phenomenon that involves not only economic activity but also social mechanisms. The intention to become an entrepreneur is a matter not only of one’s individual personality but also of one's interaction with the social environment. This study has three main objectives: predicting the existence of entrepreneurial behavioural intentions in different socio-economic conditions; examining how entrepreneurial behavioural intentions formulate entrepreneurial behaviour; and identifying how social capital influences this relationship. It also aims to reveal the differences between entrepreneurs in a relatively mature free market economy (Taiwan and a newly emerging free market economy (Mongolia. The analysis shows that socio-economic conditions affect the formation of entrepreneurial intentions. There are different approaches to building social capital in a relatively mature market and its newly emerging counterpart. The tendency of having high trust and social ties was found in Taiwanese entrepreneurs, while monitoring is commonly found among Mongolian entrepreneurs.

    Full Text Available The article deals with the analysis of the current situation on the global financial arena, analyzing the chain of cause and effect of the origins of the economic crisis and providing its possible logical outcomes. We are trying to prove here that the way the world economic situation develops will lead to either further growth or stagnation of national economies and define their position in the global business, financial, and social spheres.

    We provide an analysis of the serious transformations financial economics have been undergoing at the end of the 20th and beginning of the 21st centuries. All these changes, such as the development of international fusions on financial markets, the creation of new financial instruments, products and services, and others, have been caused largely by (and also have led to significant events in the global political arena. However, regardless of the transformations, world leadership remains in the hands of US government and business and that of their closest partners, while those societies that are not willing to support the “Americanized” world order end up on the blacklist of the World Bank, the IMF, and other international financial institutions.

    Finally, the article provides our views of the possible ways of dealing with the global economic stagnation. We highlight the importance of the strong and careful supervision of any global as well as national financial activities, the education of the public on the issues of wise investments, and the dangers of living on credit.

    The economics of land degradation has received relatively little attention until recent years. Although a number of studies have undertaken valuation of ecosystem services ranging from the global to the micro level, and quite a few studies have attempted to quantify the costs of soil erosion, studies that address the full costs of land degradation are still scarce. In this review, we attempt to analyze different land resource modeling and valuation techniques applied in earlier research and the type of data used in these analyses, and to assess their utility for different forms of land resource and management appraisal. We also report on the strengths and weaknesses of different valuation techniques used in studies on the economics of soil erosion, and the relevance of these valuation techniques. We make a case for the need for more appropriate models that can make the analysis more robust in estimating the economic costs of land degradation while recognizing the spatial heterogeneity in biophysical and economic conditions. © 2011 New York Academy of Sciences.

    Full Text Available The aim of the article is to study the strengths and weaknesses of the current reforms and provide appropriate recommendations and proposals to improve the regulatory and economic business environment. The article analyzes the introduced reforms in the aspect of the regulatory field and the active current system of taxation with the detailing of the type and content of the basic implemented measures. There have been justified the advantages and disadvantages of the introduced system of taxation with respect to the main budget forming taxes, such as the enterprise income taxes, value added tax, individual income tax considering changes in the administering of unified social tax (UST and war tax, excise duty. On the basis of the results of the study it has been found that the introduced reforms only partially improved the tax administration system and in no way reduced the announced tax burden, the time spending of business for preparing the current report was not significantly reduced.

    Skin conditions and dermatological diseases associated with advanced age (e.g. fungal infection, dry skin and itch) receive increasingly attention in clinical practice and research. Cost and economic evaluations are important sources to inform priority setting and ressource allocation decisions in healthcare. The economics of skin conditions in aged populations has not been systematically reviewed so far. The aim of this mapping review was to summarize the economic evidence of selected skin conditions in the aged (65 + years). A mapping literature review and evidence summary was conducted. Searches were conducted in data bases Medline and Embase via OVID. Cinahl was searched using EBSCO. References lists of potential eligible studies, reviews, guidelines or other sources were screened for additional literature. For evaluation of methodological quality of full economic analyses the Consensus on Health Economic Criteria (CHEC) checklist was used. Database searches resulted in 1388 records. A total of 270 articles were read in full-text. Thirty-five publications were finally included in the data analysis reporting 38 economic analyses. Ten cost of illness analyses and 26 cost-effectiveness analyses reporting about pressure ulcers, skin tears, pressure ulcers, incontinence associated dermatitis and intertrigo/contact dermatitis/candidiasis treatment and prevention and onychomycosis testing were identified. Limited evidence indicated that low air loss beds were more cost effective than standard beds for prevention of pressure ulcers. Standardized skin care regimens seem to lower the incidence of pressure ulcers, skin tears and IAD but a cost saving effect was not always observed. Findings of this mapping review indicate that there is a paucity of high quality evidence regarding the economic impact of age-associated skin conditions and diseases. Substantial heterogeneity in terms of study design, evaluation perspective, time period, and way of cost estimation was

    The aim of this paper is to show the economic potential of demand response (DR) on household level at Central European market conditions. Thereby, required economic benefits for consumers' participation, the realistic load shifting potential at household level and the estimation of essential intelligent infrastructure costs are discussed. The core of this paper builds a case-study applying spot market-oriented load shifting from the supplier's point of view by using Austrian electricity market data, household load profiles as well as a heat pump and e-car charging load profile. It is demonstrated which cost savings for suppliers can be derived from such load shifting procedure at household level. Furthermore, upper cost limits for intelligent infrastructure in order to break-even are derived. Results suggest to take a critical look at European discussions on DR implementation on household level, showing that at Central European market conditions the potential for DR at household level is restricted to significant loads and hence, the applied load shifting strategy is only beneficial with application to heat pumps. In contrast, the frequently discussed shifting of conventional household devices' loads (such as washing machines) economically does not add up. - Highlights: • Calculation of economic potential of domestic DR at Central European market conditions. • Model and case-study of spot market-oriented load shifting from supplier's perspective. • Derivation of supplier's cost savings and upper cost limits for ICT infrastructure. • Results show economic potential of domestic DR to be restricted to significant loads. • Shifting of washing machines economically does not pay off in contrast to heat pumps

    Several publications have documented the effects of economic recessions on health. However, little is known about how economic recessions influence working conditions, especially among vulnerable workers. To explore the effects of 2008 economic crisis on the prevalence of adverse psychosocial working conditions among Spanish and foreign national workers. Data come from the 2007 and 2011 Spanish Working Conditions Surveys. Survey year, sociodemographic, and occupational information were independent variables and psychosocial factors exposures were dependent variables. Analyses were stratified by nationality (Spanish versus foreign). Prevalence and adjusted prevalence ratios (aPRs) of psychological job demands, job control, job social support, physical demands and perceived job insecurity were estimated using Poisson regression. The Spanish population had higher risk of psychological and physical job demand (aPR = 1.07, 95% CI = [1.04-1.10] and aPR = 1.05, 95% CI = [1.01-1.09], respectively) in 2011 compared to 2007. Among both Spanish and foreign national workers, greater aPR were found for job loss in 2011 compared to 2007 (aPR = 2.47, 95% CI = [2.34-2.60]; aPR = 2.44, 95% CI = [2.15-2.77], respectively). The 2008 economic crisis was associated with a significant increase in physical demands in Spanish workers and increased job insecurity for both Spanish and foreign workers.

    2016-03-01

    Full Text Available The article deals with the questions of the definition of the semi-constant component of current liabilities of a bank. The purpose of this article is to develop a scientific and methodological approach to determine the semi-constant component of the current liabilities of a bank under the conditions of the complexity of data acquisition and processing of the data on factors that influence on demand deposits. The main hypothesis is the assumption of the heterogeneity of the variance of the daily cumulative sum of demand deposits. The analysis of scientific and methodological approaches that allow determining a stable component of current liabilities proves the need for further improvement of scientific instruments. In particular, a coefficient analysis that is proposed by some of the scholars, mainly, considers the average values of turnover on accounts, which in turn, can vary considerably throughout the calendar year. The use of the probability distributions to determine the expected value of the constant sum of deposits is possible only in the case of “ideal” financial conditions, when the impact of factors on the aggregate sum of deposits is not taken into account. The developed statistical models leave out the possible heterogeneity of the dispersion of this balance. In the article, it is proposed to apply econometric methods, namely, the methods of time series analysis to test the hypothesis of the variance heterogeneity of the cumulative sum of demand deposits, using daily data. In particular, the formalization and evaluation of EGARCH-model parameters are conducted. The EGARCH-model allows to take into account the non-linear, asymmetric effects of fluctuations in the financial series. The determination of the conditionalconstant component of demand deposits is proposed on the basis of the revealed regularities. The results of the research prove the hypothesis of the non-stationary character of the variance in daily balance of demand

    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.

    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. On the Question of Studying the Role of Social Capital under the Conditions of the Socio-Economic Crisis

    Directory of Open Access Journals (Sweden)

    Dmitrii Vladimirovich Afanas’ev

    2015-09-01

    Full Text Available The concept of social capital has gained considerable popularity in the social sciences, as well as in practical politics on a national and international scale. Its heuristic potential is confirmed by numerous studies demonstrating the positive impact of the level and types of social capital on a wide range of economic, social and political phenomena, and especially the use of the concept of social capital to study economic growth and development issues. However, there is no universally accepted definition of social capital, and there is no unanimous opinion concerning the ways of measuring it. The paper contains a review of the current status of the theoretical field of the concept; it shows that researchers from different countries are interested in the impact of social capital on economic growth and development at the regional level. Specific comparative studies in different countries and regions strongly support the presence of a correlation that proves social capital is one of the powerful driving forces of development. However, since the majority of studies on the effects of social capital on economic development are concentrated in the developed countries of Western Europe and the USA, it is important to evaluate the potential of this approach in the countries of post-Communist development that have different experience, in particular, in Russia. In this regard, the article points out that there is a clear lack of such studies with regard to Russia’s regions, where there are only occasional fragmentary attempts to study social capital. The aim of the paper is to substantiate on the theoretical basis and to indicate the prerequisites for empirical studies on the effects of social capital of regions on their economic growth and development, especially under the conditions of the general economic and structural crisis

Lately in the modern world in many socio-economic areas of human life quite often there are thematic challenges of managerial decision-making in a conflict environment and competition, when several in the General case, reasonable working actors perform collective decision-making, and the benefits of each depends not only on the chosen business strategies, but also from management decisions of other partners and the success of the experiments. Therefore, it is necessary to develop and substantiation of optimum variants of decision of choice of forces and means to perform tasks in conditions of uncertainty, that is also acceptable for military units. The actual problem currently is to optimize system control engineering-airfield security, the components of which perform their tasks under conditions of uncertainty. Analysis of opportunities of technical means (unmanned aerial vehicles shows that under the condition of equipping them with the appropriate equipment can be considered about the possibility of their use as part of a complex of technical means for inspection of airfields after the who enemy action in the runway. Therefore, the scientific goal in this article is to examine the possibilities of using technical means for inspection of airfield engineering and airfield services, and the aim of the study is using mathematical methods to justify the choice of the most effective means, from the point of view of economic cost of its introduction and use when performing tasks in conditions of uncertainty.

    Full Text Available Real estate investments are one of the most attractive business opportunities in the context of the contemporary economy, generally marked by economic recession and especially by monetary and financial instability. Last years international reporting concluded that deepening the global economic crisis determined an increase of the real estate request, while despite all expectations one did not assist a crash of the prices. Economic reality showed that real estate assets value (buildings, land kept proportions with economic reality over time. A comparison between stock exchange market and the real estate market shows that while an movables investor (investments in stocks, bonds or life insurance might lose completely his initial investment, the investments in real estate assets, such as buildings, would keep their quality as goods and would also keep a value to better resist shocks and thus allowing an increase of the capital. When appreciating the value of an investment the first things to analyze are the return, liquidity and risk criteria, which are essential in real estate investments too. Stimulating real estate market must be not only a wish but also a reality of global economy, since it can correct many of the aggregated indicators of a country. Containing scientifically detached from economic practice, this article is addressed to readers with interests in real estate investment. The language is usually referred particularly to the qualitative side of the real estate market approach. The feasibility of the real estate investments is being conditioned by their capacity to generate important profits, on the background of the reduction of the duration of recovery of their value. The economic instability from the last couple of years has generated fears and failures but, paraphrasing Johann Wolfgang von Goethe, courage is a mixture of genius, magic and power that helps us succeed in everything we set our mind to.

    Purpose The prevalence of cancer survivorship and chronic health conditions is increasing. Limited information exists on the economic burden of chronic conditions among survivors of cancer. This study examines the prevalence and economic effect of chronic conditions among survivors of cancer. Methods Using the 2008 to 2013 Medical Expenditure Panel Survey, we present nationally representative estimates of the prevalence of chronic conditions (heart disease, high blood pressure, stroke, emphysema, high cholesterol, diabetes, arthritis, and asthma) and multiple chronic conditions (MCCs) and the incremental annual health care use, medical expenditures, and lost productivity for survivors of cancer attributed to individual chronic conditions and MCCs. Incremental use, expenditures, and lost productivity were evaluated with multivariable regression. Results Survivors of cancer were more likely to have chronic conditions and MCCs compared with adults without a history of cancer. The presence of chronic conditions among survivors of cancer was associated with substantially higher annual medical expenditures, especially for heart disease ($4,595; 95% CI, $3,262 to $5,927) and stroke ($3,843; 95% CI, $1,983 to $5,704). The presence of four or more chronic conditions was associated with increased annual expenditures of $10,280 (95% CI, $7,435 to $13,125) per survivor of cancer. Annual lost productivity was higher among survivors of cancer with other chronic conditions, especially stroke ($4,325; 95% CI, $2,687 to $5,964), and arthritis ($3,534; 95% CI, $2,475 to $4,593). Having four or more chronic conditions was associated with increased annual lost productivity of $9,099 (95% CI, $7,224 to $10,973) per survivor of cancer. The economic impact of chronic conditions was similar among survivors of cancer and individuals without a history of cancer. Conclusion These results highlight the importance of ensuring access to lifelong personalized screening, surveillance, and chronic

    Full Text Available The aim of the article is to analyze the content interpretation of categorical concepts of economic development of production functioning under conditions of dynamic changes in the exploitation of the external environment. The article presents the author’s interpretation of the concepts of economic development and economic growth under conditions of dynamic changes in the external environment. The urgency of unification and systematization of the main interpretations of economic growth as a means of choosing and using certain management solutions under specific production conditions is substantiated. Based on the construction of the Ishikawa diagram, the reasons and difficulties of the economic growth of enterprises are graded. The conditions and factors of the conceptual apparatus of innovation activity under uncertainty are structured. It is shown that the complex application of iterative methods and methods of factor analysis provides a holistic perception of the dominant tendencies of economic development under conditions of dynamic changes in the external environment.

    We explore the correlation between disease specific estimates of economic losses and the burden of disease. This is based on data for Norway in 2013 from the Global Burden of Disease (GBD) project and the Norwegian Directorate of Health. The diagnostic categories were equivalent to the ICD-10 chapters. Mental disorders topped the list of the costliest conditions in Norway in 2013, and musculoskeletal disorders caused the highest production loss, while neoplasms caused the greatest burden in terms of DALYs. There was a positive and significant association between economic losses and burden of disease. Neoplasms, circulatory diseases, mental and musculoskeletal disorders all contributed to large health care expenditures. Non-fatal conditions with a high prevalence in working populations, like musculoskeletal and mental disorders, caused the largest production loss, while fatal conditions such as neoplasms and circulatory disease did not, since they occur mostly at old age. The magnitude of the production loss varied with the estimation method. The estimations presented in this study did not include reductions in future consumption, by net-recipients, due to premature deaths. Non-fatal diseases are thus even more burdensome, relative to fatal diseases, than the production loss in this study suggests. Hence, ignoring production losses may underestimate the economic losses from chronic diseases in countries with an epidemiological profile similar to Norway. Copyright © 2017 Elsevier B.V.

    Health worker migration is an issue of first order concern in global health policy circles and continues to be the subject of much policy debate. In this paper, we contribute to the discussion by studying the impact of economic conditions on the migration of physicians from developing countries. To our knowledge, this is one of the first papers to do so. A major contribution of this paper is the introduction of a new panel dataset on migration to the US and the UK from 31 sub-Saharan Africa countries. The data spans the period 1975-2004. Using this data, we estimate the impact of changes in economic conditions on physician migration. In our preferred specification that allows for country-specific time trends, we find that a temporary one percentage point decline in GDP per capita increases physician migration in the next period by approximately. 3 percent. In our IV models a one percentage point decline in GDP per capita increases physician migration in the next period by between 3.4 and 3.6 percent. Overall, our results suggest a significant effect of developing country economic conditions on physician migration. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The optimized synergy conditions between electron cyclotron current drive (ECCD) and lower hybrid current drive (LHCD) with normal parameters of the EAST tokamak are studied by using the C3PO/LUKE code based on the understanding of the synergy mechanisms so as to obtain a higher synergistic current and provide theoretical reference for the synergistic effect in the EAST experiment. The dependences of the synergistic effect on the parameters of two waves (lower hybrid wave (LHW) and electron cyclotron wave (ECW)), including the radial position of the power deposition, the power value of the LH and EC waves, and the parallel refractive indices of the LHW (N ∥ ) are presented and discussed.

    Inspired by the 'Fundamental Cause Theory (FCT)' we explore social inequalities in preventable versus relatively less-preventable illnesses in Spain. The focus is on the education-health gradient, as education is one of the most important components of an individual's socioeconomic status (SES). Framed in the context of the recent economic crisis, we investigate the education gradient in depression, diabetes, and myocardial infarction (relatively highly preventable illnesses) and malignant tumors (less preventable), and whether this educational gradient varies across the regional-economic context and changes therein. We use data from three waves of the Spanish National Health Survey (2003-2004, 2006-2007, and 2011-2012), and from the 2009-2010 wave of the European Health Survey in Spain, which results in a repeated cross-sectional design. Logistic multilevel regressions are performed with depression, diabetes, myocardial infarction, and malignant tumors as dependent variables. The multilevel design has three levels (the individual, period-regional, and regional level), which allows us to estimate both longitudinal and cross-sectional macro effects. The regional-economic context and changes therein are assessed using the real GDP growth rate and the low work intensity indicator. Education gradients in more-preventable illness are observed, while this is far less the case in our less-preventable disease group. Regional economic conditions seem to have a direct impact on depression among Spanish men (y-stand. OR = 1.04 [95 % CI: 1.01-1.07]). Diabetes is associated with cross-regional differences in low work intensity among men (y-stand. OR = 1.02 [95 % CI: 1.00-1.05]) and women (y-stand. OR = 1.04 [95 % CI: 1.01-1.06]). Economic contraction increases the likelihood of having diabetes among men (y-stand. OR = 1.04 [95 % CI: 1.01-1.06]), and smaller decreases in the real GDP growth rate are associated with lower likelihood of myocardial infarction among

    Full Text Available Projects are by their very nature subject to conditions of uncertainty that obstruct the decision-making process. Uncertainties involving forestry projects are even greater, as they are combined with time of return on capital invested, being medium to long term. For successful forest planning, it is necessary to quantify uncertainties by converting them into risks. The decision on whether to adopt replacement regeneration or coppice regeneration in a forest stand is influenced by several factors, which include land availability for new forest crops, changes in project end use, oscillations in demand and technological advancement. This study analyzed the economic feasibility of replacement regeneration and coppice regeneration of eucalyptus stands, under deterministic and under risk conditions. Information was gathered about costs and revenues for charcoal production in order to structure the cash flow used in the economic analysis, adopting the Net Present Value method (VPL. Risk assessment was based on simulations running the Monte Carlo method. Results led to the following conclusions: replacement regeneration is economically viable, even if the future stand has the same productivity as the original stand; coppice regeneration is an economically viable option even if productivity is a mere 70% of the original stand (high-tree planted stand, the best risk-return ratio option is restocking the stand (replacement regeneration by one that is 20% more productive; the probabilistic analysis running the Monte Carlo method revealed that invariably there is economic viability for the various replacement and coppice regeneration options being studied, minimizing uncertainties and consequently increasing confidence in decision-making.

    Full Text Available The present article analyzes the viewpoints of scientists of different economic directions on the possibility and expediency of tax policy coordination in the countries-participants of economic and monetary associations. The authors assess the role of tax instruments in the regional integration associations, study the differences in the tax systems of the countries of the Eurasian Economic Union, which restrain the integration processes within the union. The influence of the fiscal policy of the EAEU member countries on the state of their economies is studied. The authors of the article believe that, in the context of deepening integration in the EAEU, the deliberate distribution of powers in the field of tax regulation between state and supranational authorities ensuring a consistent approximation of tax systems of the participating countries taking into account the economic situation and interests of all members of the association, gains particular relevance. The measures on ensuring the elimination of double taxation within the union are proposed. The authors come to the conclusion that it is necessary to harmonize the tax policies of the member countries of the association. At the same time, the harmonization of taxation in the countries of the union should become a condition, the observance of which is necessary for the formation of a currency zone in the territory of the Unified Energy System. The article presents a set of measures aimed at ensuring equal conditions for taxing business in the EAEU. Particular attention is paid to the study of the possibility of expanding the revenues and expenditures of the unified budget of the EAEU with a view to providing financial support to projects aimed at accelerating the processes of economic and monetary integration. The authors consider it expedient to redistribute part of the national income of the participating countries to the depressed regions of the association, provided that these measures

    Superconducting magnets are energized through helium vapour-cooled cryogenic current leads operating at high ratios of current to mass flow. The high current operation where lead temperature, runaway, and eventual burn-up are likely to occur is investigated. A simple criterion for estimating the burn-up operation conditions (current, mass flow) for a given lead geometry (cross-sectional area, length, heat exchanger area) is presented. This article stresses the role played by the available heat exchanger area in avoiding burn-up at high ratios of current to mass flow. (author)

    2016-01-01

    This study models fundamental features of current and prospective policies encouraging adoption of residential photovoltaic (PV) systems. A key finding is that time-of-day (ToD) pricing can enhance or worsen the economics of PV systems. Moreover, increased responsiveness of electricity demand to its price diminishes the effectiveness of ToD pricing in the absence of net metering, but does not affect it otherwise. An application to plausible conditions in the State of Indiana, USA, shows that current policies are unlikely to trigger adoption by a risk-neutral forward-looking residential customer. However, adoption of PV systems can be induced if the Federal Tax Credit is increased to cover 48% of capital cost (instead of the current 30%), which could imply a cost to the Federal Government of about $0.95/kW of installed capacity depending on the panel’s size. We demonstrate that implementation of ToD pricing can trigger adoption under a range of on- and off-peak price combinations. But our analysis also shows that the cost-effectiveness of ToD pricing is enhanced at higher ratios of on-peak to off-peak prices. - Highlights: •Time-of-day (ToD) pricing can enhance or worsen the economics of PV systems. •Effect of ToD is independent of demand elasticity if combined with net metering. •Adoption of PV system requires that Federal Tax Credit cover half of capital cost. •To induce adoption, ToD must act as a tax on grid electricity. •Cost-effectiveness of ToD enhanced at higher ratios of on-peak to off-peak prices.

    Full Text Available The implementation of modern banking activities involves the realization of investments. Investment is a complex discussion economic category, characterized by a number of features. The types and forms of investment are manifold and can be transformed with account of the state of the economy and the level of development of industrial relations. The faster growth of the financial sector in the economy has stipulated the development of financial investment. Banks as financial and lending institutions actively make financial investments in securities. Banks’ investment in securities pursues a number of purposes which determine the selection of securities for investment and their quality. The article identified the targets of bank investments in securities and their development trends under current conditions on the basis of the analysis of the actual data for 2010–2014. Negative revaluation and the actual decrease in the value of corporate securities of Russian issuers reduce their commercial appeal. Banks refuse to speculate on the stock market in favor of the securities that ensure liquidity. Banks’ investments aim to purchasing securities from the Lombard List of the Bank of Russia in order to obtain loans and participate in the repo transactions. Thus, during the analyzed period, banks’ investments in securities transformed from systemically important assets that generate substantial profit into the mechanism that provides liquidity. It should be noted that a significant part of investment resources of Russian banks services the debt obligations of Russia’s Government. The article also identified a trend of banks’ increasing investment in the participation portfolios of subsidiaries and associated joint stock companies. The official data of the Central Bank of the Russian Federation (Bank of Russia [15], and the Federal State Statistics Service [14] were used as the information base for the study

    2017-04-01

    Full Text Available The article considers the need to update approaches to hedging the financial risks of small businesses. Reducing the probability of financial costs and losses is of continuing relevance. It appears to be especially critical for small businesses. Small business plays a significant role in the country’s economic system as creator of jobs and as a producer of goods and services that adapts quickly to changing consumer requirements. However, its access to credit resources has certain limitations. The instability of the economic environment by individual factors can affect small businesses not less, and sometimes even more than large and medium-sized businesses. Design of the risk-management in terms of small business needs to be updated. In the current context, there is a need in re-evaluating that the efficient financial risk management can only be carried out in a complex of all the enterprise’s risks, with an increase in the planning horizon and the identification of obstacles to achieving the objective set.

    Full Text Available This work shows a sensitivity analysis of the economic impact of different energy performances of air-conditioning within the Mexican housing sector. For this purpose, a cooling-load calculator program in function of the indoor temperature is developed. The program also calculates the electricity consumption along with the expenditure with the different residential rates of the Mexican Federal Commission of Electricity (CFE, initials in Spanish set according to the season of the year and zone of the country. After the results onto the national-scale scenario are validated with the literature, a sensitivity analysis is carried out by changing three parameters that are considered as influential on the consumption and which can be considered as energy saving strategies. With these strategies, it is found that the indoor temperature decrease due to the use of a passive cooling system is the most important characteristic to take into account followed by the coefficient of performance (COP of the air-conditioning and the increase of the comfort temperature set-point, respectively. Thereby, an economic analysis is carried out, finding an annual saving up to 770 USD within a single air-conditioned dwelling having a payback period of 3 years for using a combination of passive cooling techniques and increasing the comfort temperature set-point; or a 2 years payback period if the air-conditioning is changed by a high-efficient equipment.

    The UK Water Industry currently generates approximately 800GWh pa of electrical energy from sewage sludge. Traditionally energy recovery from sewage sludge features Anaerobic Digestion (AD) with biogas utilisation in combined heat and power (CHP) systems. However, the industry is evolving and a number of developments that extract more energy from sludge are either being implemented or are nearing full scale demonstration. This study compared five technology configurations: 1 - conventional AD with CHP, 2 - Thermal Hydrolysis Process (THP) AD with CHP, 3 - THP AD with bio-methane grid injection, 4 - THP AD with CHP followed by drying of digested sludge for solid fuel production, 5 - THP AD followed by drying, pyrolysis of the digested sludge and use of the both the biogas and the pyrolysis gas in a CHP. The economic and environmental Life Cycle Assessment (LCA) found that both the post AD drying options performed well but the option used to create a solid fuel to displace coal (configuration 4) was the most sustainable solution economically and environmentally, closely followed by the pyrolysis configuration (5). Application of THP improves the financial and environmental performance compared with conventional AD. Producing bio-methane for grid injection (configuration 3) is attractive financially but has the worst environmental impact of all the scenarios, suggesting that the current UK financial incentive policy for bio-methane is not driving best environmental practice. It is clear that new and improving processes and technologies are enabling significant opportunities for further energy recovery from sludge; LCA provides tools for determining the best overall options for particular situations and allows innovation resources and investment to be focused accordingly.

    Full Text Available The article is aimed at monitoring the condition of the natural and economic use of land on the basis of methods for integrated evaluation as well as determining the levels of intensity of land use at the regional level. Various views on evaluation of the condition of land have been considered. As the main attributes of the intensity of land use were accepted the agro-landscape ecological stability, the anthropogenic load, the ploughness of territory, the ploughness of agricultural land, the agricultural development of territory, and the recreational capacity. On the basis of methods for integral evaluation both the subjective and the objective importance of attributes has been determined, the integral indicators of intensity of land use have been calculated. Three levels of intensity of natural and economic use of land in the districts of Poltava region have been allocated, boundaries of the quantitative values of indicators have been determined. Prospect for further research is to evaluate the intensity of natural and economic land use at the national level in order to define a strategy for the rational use and protection of land in Ukraine and to formulate the directions of development of the regional land use on the basis of system approach.

    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

    Electro - technical devices are considered as the most prospective use for high temperature superconductors. For such devices the overload currents due to faults in grids are the operational reality. In these cases the fault currents may forcibly go to superconductors being sometimes dozens times more than the critical currents of HTS. Overloads are the working modes for fault current limiters also. To understand the behavior of HTS devices at overloads it is important to study voltage-current characteristics (VCC) of basic HTS tapes in real cooling conditions. The knowledge of VCC permits to model and to simulate properly HTS devices behavior at overloads. We performed the study of VCC of several HTS tapes at currents several times more than their critical ones. Both, 1-G and 2-G tapes were tested. There were found peculiarities or 'spikes' on VCC at rising currents that vanished at decaying currents. It was shown that such peculiarities are determined by the change of cooling conditions from the convective heat exchange to the nucleate boiling. Nucleate boiling activation and development times were determined. Their dependencies on heat release were measured. The data obtained can be used in simulation of heating of real superconducting devices at overload conditions

    Prosocial emotions related to self-blame are important in guiding human altruistic decisions. These emotions are elevated in major depressive disorder (MDD), such that MDD has been associated with guilt-driven pathological hyper-altruism. However, the impact of such emotional impairments in MDD on different types of social decision-making is unknown. In order to address this issue, we investigated different kinds of altruistic behaviour (interpersonal cooperation and fund allocation, altruistic punishment and charitable donation) in 33 healthy subjects, 35 patients in full remission (unmedicated) and 24 currently depressed patients (11 on medication) using behavioural-economical paradigms. We show a significant main effect of clinical status on altruistic decisions (p = 0.04) and a significant interaction between clinical status and type of altruistic decisions (p = 0.03). More specifically, symptomatic patients defected significantly more in the Prisoner's Dilemma game (p guilt elicited by receiving unfair financial offers in the Ultimatum Game (p guilt-driven pathological hyper-altruism hypothesis in depression. There were also differences in both current and remitted patients in the relationship between altruistic behaviour and pathological self-blaming, suggesting an important role for these emotions in moral and social decision-making abnormalities in depression.

    2010-11-01

    Full Text Available Working conditions of agricultural workers, like industrial, are one of the burning issues in a developing region. It is related to agricultural activities of the workers and their socio-economic status. Working conditions may be both favourable and unfavourable. Those working conditions which are unfavourable to health may be considered as occupational hazards or as a part of occupational environment. It is generally observed that a large section of the agricultural workers remains engaged in agricultural practices at the time of hunger, thirst, pregnancy (women and even despite their unpleasant state of health, both mental and physical. They also continue to work for more than the prescribed standard hours and also having half-fed. These are not positive or favourable working conditions to their health as they normally cause general weakness, fatigue, stomach disorder, dizziness, headache, loss of energy and some other similar physical, mental and psychological problems. The major driving forces behind as such adverse working conditions and its consequences are the pressure of work, pressure of land owners and of timely completion of works, shortage of manpower, psychological attitude, ignorance, weather constraints, poverty, illiteracy, lack of work related health awareness, lower social and economic status, etc. Such forces compel the workers to be engaged in their agricultural practices under the above circumstance. Adverse working conditions of agricultural workers vary widely with reference to space, time, activities, demographics, society, economy and consequently affect both the mental and physical, social and psychological conditions of the agricultural workers. Persons in varying number in the age groups from 15-34 and 35-49 to 60 & + year were reported working under different types of undesirable working conditions. The people from the S.C. and S.T. categories are the major sufferers as most of them continue their work during

    In this paper, a new reference current computation method suitable for shunt active power filter control under distorted voltage conditions is proposed. The active power filter control is based on the use of self-tuning filters (STF) for the reference current generation and on a modulated hysteresis current controller. This active filter is intended for harmonic compensation of a diode rectifier feeding a RL load under distorted voltage conditions. The study of the active filter control is divided in two parts. The first one deals with the harmonic isolator which generates the harmonic reference currents and is experimentally implemented in a DS1104 card of a DSPACE prototyping system. The second part focuses on the generation of the switching pattern of the inverter by using a modulated hysteresis current controller, implemented in an analogue card. The use of STF instead of classical extraction filters allows extracting directly the voltage and current fundamental components in the {alpha}-{beta} axis without phase locked loop (PLL). The performances are good even under distorted voltage conditions. First, the effectiveness of the new proposed method is mathematically studied and verified by computer simulation. Then, experimental results are presented using a DSPACE system associated with the analogue current controller for a real shunt active power filter. (author)

    Full Text Available The construction industry is one of the key fund-creating industries, the formation of the Russian economy greatly depends on it. The construction sector is cyclic, that’s why it has always been sensitive to the tendencies of the national economy. In the contemporary conditions of weak economical climate the construction industry is in a state of sluggish recession. The key indicators exercising restraining influence on the construction complex are analyzed. The author carried out calculations of the prices for residential real estate in the past years. The author’s view on the near-term prospects on the exit from recession state is formulated. From the view of the today’s state and the nearest development prospects, it can be stated that the construction industry is one of the most problematic among the basic economic sectors. Retrieval of the expansion rate of the construction industry is possible in case of the positive changes of general economic state.

  6. Impact of Economic Conditions and Crises on Mortality and its Predictability.

    Bohk, Christina; Rau, Roland

    To investigate how economic conditions and crises affect mortality and its predictability in industrialized countries, we review the related literature, and we forecast mortality developments in Spain, Hungary, and Russia-three countries which have recently undergone major transformation processes following the introduction of radical economic and political reforms. The results of our retrospective mortality forecasts from 1991 to 2009 suggest that our model can capture major changes in long-term mortality trends, and that the forecast errors it generates are usually smaller than those of other well-accepted models, like the Lee-Carter model and its coherent variant. This is because our approach is capable of modeling (1) dynamic shifts in survival improvements from younger to older ages over time, as well as (2) substantial changes in long-term trends by optionally complementing the extrapolated mortality trends in a country of interest with those of selected reference countries. However, the forecasting performance of our model is limited (like that of every model): e.g., if mortality becomes extremely volatile-as was the case in Russia after the dissolution of the Soviet Union-generating a precise forecast will depend more on luck than on methodology and expert judgment. In general, we conclude that, on their own, recent economic changes appear to have minor effects on life expectancy in industrialized countries, but that the effects of these changes are greater if they occur in conjunction with other major social and political changes.

    Two hundred and four patients who underwent renal transplantation were followed up as outpatients with a minimum of four years. They were divided into two socio-economic levels: group I - 104 patients who underwent transplantation in a private hospital and 120 patients (group II) with a lower socio-economic standard, treated in a public hospital. In both groups urinary infections and hepatitis were excluded. The incidence of infection in group I was 24% and in group II, 50% (p = 0.0002). There was no difference in relation to viral infection in either groups. However, bacterial infection and infection by opportunistic agents were significantly higher in group II (p = 0.0001 and p = 0.0282). The number of hospitalizations and the number of infections of patients were higher in group II. There was a tendency for an increase in mortality owing to infection in group II. There was no difference in the two groups as the parameters of: age, sex, type of donor, primary disease, number of rejections crises, level of serum creatinine and number of patients with ciclosporine. On the other hand, the dose of azathioprine and prednisone was mildly higher in those patients of group II. Low level of socio-economic conditions is a risk factor in renal transplant patients.

    Full Text Available The article emphasizes the importance of the concept of «technical and economic paradigm», which characterizes the certain stage of the world economy development associated with the corresponding technological revolution. The paper reveals the feature of the modern technical and economic paradigm development connected with new concepts determining a priority of general values. The author states the hypothesis that in the conditions of the emergence of the fourth industrial revolution elements (so-called 4.0 industry, it is fair to consider the innovation paradigm of development as the foundation of the new industrialization which preceds this revolution. The author considers new industrialization as the process contributing to the global technological parity of Russia and the countries-technological leaders. The most significant statements from this post of view are allocated: consideration of new industrialization as a process of continuous innovations and distribution of breakthrough technologies, computerization of production, robotization, cross-disciplinary nature of high technologies, the ecology of technologies, intellectualization of the potential of all persons occupied in industrial production, etc. The author analyses strategic documents connected with the development of innovative activities in Russia. The paper emphasizes that the indicators characterizing these activities do not allow to rank Russia as a country having the developed innovative economy. The article reveals the possibilities of the activation of innovative activities in Russia connected to the development of the approved private priorities in the main spheres of activity with the state priorities of social development; with construction of integrated strategy of a scientific and technological, institutional and industrial development of the country; with creation of the system of scientific monitoring allowing to adjust the necessary corrective actions in time.

    Individuals can react to financial stress in a variety of ways, such as reducing discretionary spending or engaging in risky behaviors. This article investigates the effect of changing macroeconomic conditions (measured by the unemployment rate in the state of residence) on one type of risky behavior: excessive alcohol consumption. Using unique and recent panel data from waves 1 and 2 of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC) and estimating fixed-effects models, we find that changes in the unemployment rate are positively related to changes in binge drinking, alcohol-involved driving, and alcohol abuse and/or dependence. Some differences are present among demographic groups, primarily in the magnitude of the estimated effects. These results contradict previous studies and suggest that problematic drinking may be an indirect and unfortunate consequence of an economic downturn. Copyright © 2011 John Wiley & Sons, Ltd.

    Non-communicable diseases (NCDs) are becoming a major source of the national disease burden in Myanmar with potentially serious economic implications. Using data on 5484 households from the World Health Survey (WHS), this study assessed the household-level economic burden of two chronic conditions, angina and asthma, in Myanmar. Propensity score matching (PSM) and coarsened exact matching (CEM) methods were used to compare household out-of-pocket (OOP) spending, catastrophic and impoverishment effects, reliance on borrowing or asset sales to finance OOP healthcare payments and employment among households reporting a member with angina (asthma) to matched households, with and without adjusting for comorbidities. Sensitivity analyses were carried out to assess the impacts of alternative assumptions on common support and potential violations of the assumption of independence of households being angina (asthma) affected and household economic outcomes, conditional on the variables used for matching (conditional independence). Households with angina (asthma) reported greater OOP spending (angina: range I$1.94-I$4.31; asthma: range I$1.53-I$2.01) (I$1 = 125.09 Myanmar Kyats; I$=International Dollar) almost half of which was spending on medicines; higher rates of catastrophic spending based on a 20% threshold ratio of OOP to total household spending (angina: range 6-7%; asthma: range 3-5%); greater reliance on borrowing and sale of assets to finance healthcare (angina: range 12-14%; asthma: range 40-49%); increased medical impoverishment and lower employment rates than matched controls. There were no statistically differences in OOP expenses for inpatient care between angina-affected (asthma-affected) households and matched controls. Our results were generally robust to multiple methods of matching. However, conclusions for medical impoverishment impacts were not robust to potential violations of the conditional independence assumption. Myanmar is expanding public

    Heavy Quark Effective Theory (HQET) computations of semi-leptonic decays, e.g. B{yields}{pi}l{nu}, require the knowledge of the parameters in the effective theory for all components of the heavy-light flavor currents. So far non-perturbative matching conditions have been employed only for the time component of the axial current. Here we perform a check of matching conditions for the time component of the vector current and the spatial component of the axial vector current up to one-loop order of perturbation theory and to lowest order of the 1/m-expansion. We find that the proposed observables have small higher order terms in the 1/m-series and are thus excellent candidates for a non-perturbative matching procedure.

  13. Out-patient management and non-attendance in the current economic climate. How best to manage our resources?

    2010-03-01

    Outpatient non-attendance is a considerable source of inefficiency in the health service, wasting time, resources and potentially lengthening waiting lists, Given the current economic climate, methods need to be employed to reduce non-attendance. The aim was to analyse outpatient non-attendance and determine what factors influence attendance. A prospective audit over a two-month period to a tertiary-referral Urological service was performed to determine the clinical and demographic profile of non-attendees. Of 737 appointments, 148 (20%) patients did not attend (DNA). A benign urological condition was evident in 116 cases (78%). This group of patients also accounted for the majority of new patients not attending 40\\/47, returning patients not attending 101\\/148 and the majority of patients who missed multiple appointments 43\\/49. Patients with benign conditions make up the majority of clinic non-attendance. Consideration may be given to discharging such patients back to their general practitioner after one unexplained non-attendance until other alternatives of follow up are available.

    In new conditions of socio-economic development in the Ukraine, the health of the population of children is considered as the most reliable indicator of socio-economic development of the country. The primary goal of the study was analysis of the effect of contemporary socio-economic transformations, their scope, and strength of effect on the demographic and social situation of children in various regions of the Ukraine. The methodological objectives of the study were as follows: development of a synthetic measure of the state of health of the population of children, based on the Hellwig's method, and selection of districts in the Ukraine according to the present health-demographic situation of children. The study was based on statistical data from the State Statistics Service of Ukraine, Centre of Medical Statistics in Kiev, Ukrainian Ministry of Defence, as well as Ministry of Education and Science, Youth and Sports of Ukraine. The following research methods were used: analysis of literature and Internet sources, selection and analysis of statistical materials, cartographic and statistical methods. Basic indices of the demographic and health situation of the population of children were analyzed, as well as factors of a socio-economic nature which affect this situation. A set of variables was developed for the synthetic evaluation of the state of health of the population of children. The typology of the Ukrainian districts was performed according to the state of health of the child population, based on the Hellwig's taxonomic method. Deterioration was observed of selected quality parameters, as well as a change in the strength and directions of effect of factors of organizational-institutional, socioeconomic, historical and cultural nature on the population of children potential.

    Full Text Available The last three centuries have witnessed a specific social evolution, one much more dynamical than those of the previous era. The general vector of this dynamics is represented by the progress in technology and science that had taken place in all arrays of social action, a phenomenon largely manifested throughout Western European countries and North America. It is against this general setup that the world saw the formation and development of both European national communities and of the capitalist market economies, two of the historical causes that lead to the fall of the feudal social and economical system.

  17. Neutron transport assembly calculation with non-zero net current boundary condition

    Fuel assembly calculation for the homogenized group constants is one of the most important parts in the reactor core analysis. The homogenized group constants of one a quarter assembly are usually generated for the nodal calculation of the reactor core. In the current nodal calculation, one or a quarter of the fuel assembly corresponds to a unit node. The homogenized group constant calculation for a fuel assembly proceeds through cell spectrum calculations, group condensation and cell homogenization calculations, two dimensional fuel assembly calculation, and then depletion calculations of fuel rods. To obtain the assembly wise homogenized group constants, the two dimensional transport calculation is usually performed. Most codes for the assembly wise homogenized group constants employ a zero net current boundary condition. CASMO-3 is such a code that is in wide use. The zero net current boundary condition is plausible and valid in an infinite reactor composed of the same kind of assemblies. However, the reactor is finite and the core is constructed by different kinds of assemblies. Hence, the assumption of the zero net current boundary condition is not valid in the actual reactor. The objective of this study is to develop a homogenization methodology that can treat any actual boundary condition, i.e. non-zero net current boundary condition. In order to treat the non-zero net current boundary condition, we modify CASMO-3. For the two-dimensional treatment in CASMO-3, a multigroup integral transport routine based on the method of transmission probability is used. The code performs assembly calculation with zero net current boundary condition. CASMO-3 is modified to consider the inhomogeneous source at the assembly boundary surface due to the non-zero net current. The modified version of CASMO-3 is called CASMO-3M. CASMO-3M is applied to several benchmark problems. In order to obtain the inhomogeneous source, the global calculation is performed. The local calculation

    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.

  2. Maximum power point tracking for PV systems under partial shading conditions using current sweeping

    2015-01-01

    Highlights: • A novel approach for tracking the maximum power point of photovoltaic systems. • Able to handle both the uniform insolation and partial shading conditions. • Maximum power point tracking based on current sweeping. - Abstract: Partial shading on photovoltaic (PV) arrays causes multiple peaks on the output power–voltage characteristic curve and local searching technique such as perturb and observe (P&O) method could easily fail in searching for the global maximum. Moreover, existing global searching techniques are still not very satisfactory in terms of speed and implementation complexity. In this paper, a fast global maximum power point (MPPT) tracking method which is using current sweeping for photovoltaic arrays under partial shading conditions is proposed. Unlike conventional approach, the proposed method is current based rather than voltage based. The initial maximum power point will be derived based on a current sweeping test and the maximum power point can be enhanced by a finer local search. The speed of the global search is mainly governed by the apparent time constant of the PV array and the generation of a fast current sweeping test. The fast current sweeping test can easily be realized by a DC/DC boost converter with a very fast current control loop. Experimental results are included to demonstrate the effectiveness of the proposed global searching scheme

    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.

    Full Text Available The subject-matter of the research is the study of the regional metallurgical complex and its leaders, which account for 55 % of industrial output and more than 57 % of exports of the Sverdlovsk region, in the current terms of economic instability. Supporting the business priorities of improving the competitiveness and economic security of the enterprise is based on the example of "UMMCHolding" — the leader of ferrous metallurgy in the Middle Urals, an active participant in the global and Russian copper market. The modern economic, mathematical, and general scientific methods (comparison study, the ratio of total and private, and others are applied as the research methods. To obtain the study results, the main areas of the holding impacted by the sanctions are analyzed: modernization of production and spare parts provisions of the current imported equipment, correction of the supply chain, searching for new business partners, transformation of the structure and direction of cargo traffic, solving transportation problems, stocks system management and minimization of economic, social and environmental costs. The urgency of solving the problem of company competitiveness and economic security increasing together with its sectoral and regional features in the present conditions is proved as the key conclusion. The high competitiveness of the holding is considered to be one of the factors of its economic security. The main goal of the economic security of the company is its sustainable and maximally effective functioning at the present time and high potential for successful development in the future. The indicators and criteria for the economic security evaluation are studied in detail. The analysis conducted has shown that, in general, the holding has high indicators characterizing its economic security on the basis of high competitiveness. As a negative sign, a lack of the investment growth needed to solve urgent problems is noticed.

    We study the time evolution of the ASEP on a finite lattice with L sites and open boundaries, conditioned on an atypically low current up to a finite time t. By an exact computation, we show that for a one-parameter family of boundary densities and a special value of the conditioned current, an initial product measure with an antishock at site k evolves into a convex combination of such antishocks at sites k′. The weights p(k′, t|k, 0) are shown to be the transition probabilities of simple biased random walk with reflecting boundaries. We compute explicitly these transition rates. Our result implies that the antishock remains microscopically stable under the locally conditioned dynamics. (paper)

    Full Text Available Ukraine and People's Republic of China (PRC are cooperating in some areas like: machinery, transportation etc. China is interested in partnering with Ukraine for selling Chinese consumer goods. Ukraine is interested in selling raw materials to China. To study this possible cross-border cooperation and commercial relationship, the current paper uses the "intensity of interaction" (namely, the depth of integration model, which is based upon the existing “gravity model”. The index for existing model has been obtained by adding a “dummy variable” in the standard "gravity model" which reflects the influence of regional nuances upon the level and direction of trade flow. The strategic partner relationship must be based on: "complementing" the economic structure of the partners, which means equality in the relationship and lack of significant disparities.

    2017-12-01

    Full Text Available In a landscape archaeology project all the fertile fields around the Sea of Galilee (an area of 50 × 30 km were mapped. The whole territory was subdivided in 5 regions: Jordan valley, Lower Galilee, Upper Galilee, Golan and Transjordanian Hill Country. Additionally all ancient sites from the Neolithic to the Persian period, which are mentioned in archaeological literature, were collected – all together more than 300 sites. These data allow a reconstruction of the economic conditions in antiquity in the area around the Sea of Galilee. Landscape archaeology clearly demonstrates that the economic basis may have been completely diverse in the five sub-regions, and also during different times. Agriculture played a major role in the economy of ancient people. During some periods and in some regions people lived in the midst of the fields, while in other periods they settled at the edges in order not to waste valuable farmland. On the other hand the position of some sites in some periods clearly demonstrates that trade played a major role for the income of the settlers, or basalt mining and working.

    Full Text Available The cancerous spread of slum has been a rampant problem in urban areas worldwide. The acute shortage of housing facilities compels the poor to live in slums. Proper rehabilitation is considered as a very essential remedial measure to provide better living environment to slum peoples. This study is an essential attempt to gauge the effectiveness of a rehabilitation program, which studies the changes in socio-economic and health condition of rehabilitated slum dwellers since they got rehabilitated. In order to do so, a household survey was carried comprising 240 households in two rehabilitated sites in the city of Kolkata (ward no. 107 and 114 during the month of July, 2014. The results conforms a strand of a belief that in-situ rehabilitation or rehabilitation within short distance is more effective. A rehabilitation too far away area disrupts the existing social, economic and political ties of neighborhoods. Measures have also been proposed to overcome such problems and to make the slum dwellers an integral part of urban society.

    Full Text Available The paper presents economic analysis of growing of legume-cereal intercropping in conditions of organic farming. Results of the analysis are based on data monitoring in chosen organic farms that grow LCI. In the paper there is also compared economic efficiency of LCI grown in organic and conventional farming system. Methodological solution results from costingness and earnings monitoring of LCI production in five chosen organic farms in the period 2007–2008.When evaluating costs existing in individual variants of LCI growing it is necessary to say that the selection of individual machines and machine aggregations represents the most important factor of influencing direct costs, namely with regard to the size of organic farms and to the area of individual field blocks. Under conditions of organic farms, the LCI production is also significantly influenced also by agrotechnical (tillage operations. As compared with conventional farms, the final yield of both green fodder and grain is lower by 14–38%. Total direct costs per hectare of harvested LCI acreage ranged in case of fodder production from 9.249 CZK to 11.620 CZK per hectare. In case of grain production, the corresponding costs ranged from 8.848 to 9.970 CZK per hectare. In case of LCI, the direct costs of organic farms per unit of production of both fodder and grain consist mainly of material costs, which represent 63–76% and 61–68% of total expenses associated with production of fodder and grain, respectively. These direct costs are influenced also by higher prices of inputs.

  16. Operating modes of high-Tc composite superconductors and thermal runaway conditions under current charging

    2006-01-01

    The operating thermal and electric modes of a high-T c superconducting composite in partially and fully penetrated states induced by the charging current are investigated. They were studied under conditions in which the current charging rate, the volume fraction of the superconductor in a composite or the temperature of the cooling bath were changed. The transient behaviour of the voltage-current dependence, which is characteristic during stable and unstable increases in electric field inside the composite under a continuous current charging, is discussed. Simulations were done using zero- and one-dimensional steady and unsteady thermoelectric models with a power equation describing the virgin voltage-current characteristic of a superconductor. It is found that some thermoelectric trends underlie the shape of the voltage-current characteristic of the high-T c superconducting composite. These have to be considered during experiments in which the critical or quench currents are defined. First, in the initial stage of the fully penetrated regime (in the low voltage range), the electric field distribution does not have a uniform character. These states depend on the volume fraction of the superconductor and the current charging rate: the higher these quantities, the higher the heterogeneity of the electric field. Second, during the stable over-critical regime (in the high voltage range) occurring in complete penetration modes, the evolution of the electric field may depend on the relevant temperature increase of a composite according to the corresponding increase in its temperature-dependent heat capacity. Consequently, the shape of the voltage-current characteristic of a composite high-T c superconductor during continuous current charging, both before and after thermal runaway, has only a positive slope. Moreover, it is proved that the growth of the fully penetrated part of the voltage-current characteristic becomes less intensive when the current charging rate or the

    Full Text Available In the modern conditions the socio-economic paradigm is changing, on the one hand, due to the transition to knowledge economy and, on the other hand, due to the need to develop innovation that determine competitiveness and the development level of national economies in the world. It is obvious that the progressive upgrade and the improvement of production processes (change in technological modes can not be implemented without the increase in the level of human capital in the society and the enhancement of potential and qualification of the workforce. These changes largely depend on the education system. In almost all world countries there is an active process of modernization and change in the system of training. New forms and approaches appear, for example lifelong education (concept “Lifelong education”, informal forms of learning, self-education, etc. Without the development of these approaches it is not possible to become a competitive state in changing social, political and economic environment. This is particularly true for countries, which experience changes in the technological mode and have the necessity to transfer to new technologies. Russia is among such countries nowadays. In our opinion, the modern reforms do not give the opportunity to fulfill the main task of education – to ensure and create conditions for self-determination and self-moralization of an individual in the society, achieve the desired level of knowledge for development of innovation in the regions. In the framework of the conducted research we get the classification of all Russian regions by indicators, such as “innovation” and “investment attractiveness”, with the levels of education being taken into account. This approach, on the one hand, shows the heterogeneity of socio-economic development of the country’s regions and, on the other hands, ‒ allows us to reveal the fact that the same federal district can include both regions-locomotives and

    Vaccinating females against human papillomavirus (HPV) prior to the debut of sexual activity is an effective way to prevent cervical cancer, yet vaccine uptake in low- and middle-income countries has been hindered by high vaccine prices. We created an economic model to estimate the distribution of the economic surplus-the sum of all health and economic benefits of a vaccine, minus the costs of development, production, and distribution-among different country income groups and manufacturers for a cohort of twelve-year-old females in 2012. We found that manufacturers may have received economic returns worth five times their original investment in HPV vaccine development. High-income countries gained the greatest economic surplus of any income category, realizing over five times more economic value per vaccinated female than low-income countries did. Subsidizing vaccine prices in low- and middle-income countries could both reduce financial barriers to vaccine adoption and still allow high-income countries to retain their economic surpluses and manufacturers to retain their profits.

    Full Text Available Abstract Background Surprisingly few studies have investigated the interplay of multiple factors affecting self-rated health outcomes and the role of social capital on health in developing countries, a prerequisite to strengthening our understanding of the influence of social and economic conditions on health and the most effective aid. Our study aimed to identify social and economic conditions for health among residents of an economically and health-deprived community. Methods Data were gathered through a survey administered to respondents from 1,020 households in Grahamstown a suburb in the Eastern Cape, South Africa (response rate 97.9%. We investigated the influence of social and economic conditions (education, employment, income, social capital, housing quality and neighborhood quality on self-rated health. We used ordinal logistic regression analyses to identify the relationship of these conditions and self-rated health. Results Our study found that education and social capital positively correlated with health; unemployment, poor educational level and advanced age negatively correlated. We found no significant correlations between self-rated health and housing quality, neighbourhood quality, income, gender, or marital status. Conclusion We highlight the possible impacts of social capital, employment, and education on health, and suggest that health outcomes may be improved through interventions beyond the health system: creating job opportunities, strengthening social capital, bettering educational systems, and promoting educational access. Policymakers should consider the benefits of such programmes when addressing health outcomes in financially distressed districts.

    We investigate the impact of both parallel and transverse boundary conditions on the current and charge transport in open field line systems using the TOKAM2D code, which solves a minimal model for interchange turbulence. Various limit test cases are discussed and analyzed. In the parallel direction, the sheath conductivity is found to play an essential role in the stabilization of large-scale potential structures, leading to the formation of transport channel or transport barrier respectively for an insulating end wall or a wall with an enhanced sheath conductivity. On another hand, the addition of transverse boundary conditions intrinsically changes the transport characteristics, influencing both radial profiles and probability density functions. It underlines that in some cases a detailed description of the plasma-wall interaction process is required to get a proper description of the current loop pattern that determines electrostatic turbulent transport.

    Full Text Available This study examines the association between state and county unemployment rates and individuals’ body weight status during the latest recession in the U.S. We used the U.S. Behavioral Risk Factor Surveillance System (BRFSS data in 2007, 2009 and 2011, which were collected from 722,692 American adults aged 18 or older. Overweight and obesity were defined as body mass index (BMI ≥25, and ≥30, respectively. Multivariate linear and logistic regressions were applied to assess the association between BMI, risks of overweight and obesity, and state and county unemployment rates. State unemployment rates were negatively associated with individual BMI across years, while county unemployment rates were significantly positively associated with BMI and obesity rates in all years (p < 0.05. However, the scale of the positive relationship was reduced in 2009 and 2011. Stratified analyses were conducted among adults with employment and without employment. The unemployed group’s body weight status was not related to state- and county-level economic conditions in most times. In the pooled analyses with all three years’ data, the relationship between unemployment rates and body weight status were consistently reduced after the recession of 2008–2009. Our results indicated that macroeconomic conditions at different levels can have different associations with individuals’ obesity risk across time.

    The report deals with the external conditions for local power production, suggested as a production close to or at the end consumer. The political, legal and economical frame conditions for such production including rating are discussed. The report shall together with a technical report regarding appropriate technologies for such production (A5712), serve as a basis for case studies and monitors later in the project. Through the case studies it will be uncovered how the external conditions are functioning which will make foundations for recommendations concerning possible alterations in the conditions in order to make the local power production more profitable. In the discussion on the political and legal external conditions the system of today is studied. From the political area the general development is described and a short analysis is made of what to expect from case handling procedures, and some challenges are pointed out At present there is a simplified handling of cases of minor and smaller power plants. In order to obtain a more realistic construction of such plants the requirements of license handling may need sharpening. The tariffing of energy deliverance is studied. The regulations for tariffing and income regulation in the distribution network is mainly designed with the consumer and the central power production in mind. A study is made of how the regulations work, to what extent precessions and additional rules are needed and to what extent alterations in the regulations are needed in order to incorporate the local power production in a rational way. While a local power producer at best, will want a price for power which is sold at the power market of the size of 20 oere/kWh, the power will increase in value further down in the voltage level. At the 230 V level the power price will be of the size of 60 oere/kWh all expenses included and the network rent (during normal precipitation conditions). Therefore the production for own consumption will be met

    Full Text Available In this paper the implementation of the DC link current estimator in power conditioning system of the variable speed wind turbine is shown. The wind turbine is connected to double feed induction generator (DFIG. The variable electrical energy parameters delivered by DFIG are fitted with the electrical grid parameters through back-to-back power converter. The bidirectional AC-AC power converter covers a wide speed range from subsynchronous to supersynchronous speeds. The modern control of back-to-back power converter involves power balance concept, therefore its load power should be known in any instant. By using the power balance control, the DC link voltage variation at the load changes can be reduced. In this paper the load power is estimated from the dc link, indirectly, through a second order DC link current estimator. The load current estimator is based on the DC link voltage and on the dc link input current of the rotor side converter. This method presents certain advantages instead of using measured method, which requires a low pass filter: no time delay, the feedforward current component has no ripple, no additional hardware, and more fast control response. Through the numerical simulation the performances of the proposed DC link output current estimator scheme are demonstrated.

For a thorough research we will divide the operator’s clients into natural persons clients and legal persons clients, each group having its specificities. The data gathering method was the questionnaire sent by post office to all the Orange Romania branches (a total of 225 branches. We received a number of 64 responses, what means a responses rate of 28.4%, which were analyzed using the SPSS informatics program focusing on the correlation analysis and factor analysis. The main results emphasize the fact that the fight to attract clients becomes more and more powerful. The very competitive market leads to the growth of the importance of the price in choosing a provider. The operators’ short term gains from the clients that prefer low prices represent a long term risk of image. Choosing some services packages is sometimes very difficult due to the complexity of the offer. The clients expect the service to work, be simple and easy to use. They want to benefit from rapid and efficient assistance if errors occur and the operator respects the clauses of the contract. The results obtained through this study, allowed us to make an opinion on the perspective that the

    2009-01-01

    The current achievements and needs toward the investigation, understanding and mechanistic prediction of the Critical Heat Flux (CHF) event, under PWR and BWR core conditions, are addressed in this paper. It is shown that, even when using advanced 3-D CFD simulation tools, the current approach to CHF mechanistic modeling has serious limitations. This is mainly due to the lack of information regarding the relevant two-phase flow pattern(s) (in particular near the heated wall) and associated mechanisms (at the meso and micro-scale) leading to the CHF event. Areas of current experimental needs are identified in order to address these shortcomings. In addition, the use of 1-D and 3-D numerical tools to mechanistically predict the CHF is discussed. It is shown that 3-D two-phase CFD codes may not be superior to 1-D codes without proper consideration of relevant constitutive relations. (author)

    The National Electrostatics Corporation's (NEC) Toroidal Volume Ion Source (TORVIS) source is known for exceptionally high proton currents with minimal service downtime as compared to traditional sputter sources. It has been possible to obtain over 150μA of proton current from the source, with over 70μA on the target stage. However, beam fluxes above ∼1×10 17 /m2-s may have many undesirable effects, especially for insulators. This may include high temperature gradients at the surface, sputtering, surface discharge, cracking or even disintegration of the sample. A series of experiments were conducted to examine the role of high current fluxes in a suite of ceramics and insulating materials. Results will show the optimal proton irradiation conditions and target mounting strategies needed to minimize unwanted macro-scale damage, while developing a procedure for conducting preliminary radiation experiments.

    Physics-based simulation results can vary widely depending on the applied boundary conditions. As a first step toward assessing the effect of boundary conditions on ring current simulations, we analyze the uncertainty of cross-polar cap potentials (CPCP) on electric field boundary conditions applied to the Rice Convection Model-Equilibrium (RCM-E). The empirical Weimer model of CPCP is chosen as the reference model and Defense Meteorological Satellite Program CPCP measurements as the reference data. Using temporal correlations from a statistical analysis of the "errors" between the reference model and data, we construct a Monte Carlo CPCP discrete time series model that can be generalized to other model boundary conditions. RCM-E simulations using electric field boundary conditions from the reference model and from 20 randomly generated Monte Carlo discrete time series of CPCP are performed for two large storms. During the 10 August 2000 storm main phase, the proton density at 10 RE at midnight was observed to be low (Dst index is bounded by the simulated Dst values. In contrast, the simulated Dst values during the recovery phases of the 10 August 2000 and 31 August 2005 storms tend to underestimate systematically the observed late Dst recovery. This suggests a need to improve the accuracy of particle loss calculations in the RCM-E model. Application of this technique can aid modelers to make efficient choices on either investing more effort on improving specification of boundary conditions or on improving descriptions of physical processes.

    Detecting replacement conditions of railway point machines is important to simultaneously satisfy the budget-limit and train-safety requirements. In this study, we consider classification of the subtle differences in the aging effect-using electric current shape analysis-for the purpose of replacement condition detection of railway point machines. After analyzing the shapes of after-replacement data and then labeling the shapes of each before-replacement data, we can derive the criteria that can handle the subtle differences between "does-not-need-to-be-replaced" and "needs-to-be-replaced" shapes. On the basis of the experimental results with in-field replacement data, we confirmed that the proposed method could detect the replacement conditions with acceptable accuracy, as well as provide visual interpretability of the criteria used for the time-series classification.

On the basis of the experimental results with in-field replacement data, we confirmed that the proposed method could detect the replacement conditions with acceptable accuracy, as well as provide visual interpretability of the criteria used for the time-series classification.

    The recent Great Recession from December 2007 to June 2009 presents a unique opportunity to examine whether the incidence of nonpalpable prostate cancer decreases while conservative management for nonpalpable prostate cancer increases during periods of national economic hardship. We derived rates of national monthly diagnosis and conservative management for screen detected, nonpalpable prostate cancer and patient level insurance status from the SEER (Surveillance, Epidemiology and End Results) database from 2004 to 2011. We derived monthly statistics on national unemployment rates, inflation, median household income and S&P 500® closing values from government sources. Using linear and logistic multivariable regression we measured the correlation of national macroeconomic conditions with prostate cancer diagnosis and treatment patterns. We evaluated patient level predictors of conservative management to determine whether being insured by Medicaid or uninsured increased the use of conservative management. Diagnosis rates correlated positively with the S&P 500 monthly close (coefficient 24.90, 95% CI 6.29-43.50, p = 0.009). Conservative management correlated negatively with median household income (coefficient -49.13, 95% CI -69.29--28.98, p management compared to that in men with private insurance. As indicated by a significant interaction term being diagnosed during the Great Recession increased the Medicaid insurance predictive value of conservative management (OR 1.30, 95% CI 1.02-1.68, p = 0.037). National economic hardship was associated with decreased diagnosis rates of nonpalpable prostate cancer and increased conservative management.

    Extensive research has demonstrated a relationship between socioeconomic factors and health among older adults, yet fewer studies have explored this relationship with older immigrants. This study aims to examine the influence of employment and self-rated economic condition on the subjective well-being of older Korean immigrants in the United States. Data were drawn from a cross-sectional study of 205 older Korean immigrants, aged 65 to 90, in Los Angeles County. Hierarchical regression was employed to explore the independent and interactive effects of employment status and self-rated economic condition. The study found that employment and self-rated economic status were positively associated with subjective well-being. Also, the interaction between employment and self-rated economic status was significantly associated with higher levels of subjective well-being, such that the influence of self-rated economic condition was stronger for unemployed older Korean immigrants compared with those who were employed. This population-based study provides empirical evidence that employment and self-rated economic condition are directly associated with subjective well-being for older Korean immigrants. © The Author(s) 2015.

    2011-12-01

    Full Text Available The issue of health has always been, both in social reality and in academia and research, a sensitive topic considering the relationship each individual has with his own health and the health care system as a public policy. At public opinion levels and not only, health care is the most important sector demanding the outmost attention, considering that individual health is the fundamental prerequisite for well-being, happiness and a satisfying life. The ever present research and practical question is on the optimal financing of the health care system. Any answer to this question is also a political decision, reflecting the social-economic value of health for a particular country. The size of the resource pool and the criteria and methods for resource allocation are the central economic problems for any health system. This paper takes into consideration the limited resources of the national health care system (the rationalization of health services, the common methods of health financing, the specificity of health services market (the health market being highly asymmetric, with health professionals knowing most if not all of the relevant information, such as diagnosis, treatment options and costs and consumers fully dependent on the information provided in each case and the performance of all hospitals in Romania, in order to assess the latest strategic decisions (introduction of co-payment and merging and reconversion of hospitals taken within the Romanian health care system and their social and economic implications. The main finding show that, even though the intention of reforming and transforming the Romanian health care system into a more efficient one is obvious, the lack of economic and demographic analysis may results into greater discrepancies nationwide. This paper is aimed to renew the necessity of joint collaboration between the economic and medical field, since the relationship between health and economic development runs both ways

    This report updates a baseline risk assessment for the 300 Area prepared in 1994. The update includes consideration of changes in contaminants of interest and in the environment that have occurred during the period of interim remedial action, i.e., 1996 to the present, as well as the sub-regions, for which no initial risk assessments have been conducted. In 1996, a record of decision (ROD) stipulated interim remedial action for groundwater affected by releases from 300 Area sources, as follows: (a) continued monitoring of groundwater that is contaminated above health-based levels to ensure that concentrations continue to decrease, and (b) institutional controls to ensure that groundwater use is restricted to prevent unacceptable exposure to groundwater contamination. In 2000, the groundwater beneath the two outlying sub-regions was added to the operable unit. In 2001, the first 5-year review of the ROD found that the interim remedy and remedial action objectives were still appropriate, although the review called for additional characterization activities. This report includes a current conditions baseline ecological and human health risk assessment using maximum concentrations in the environmental media of the 300-FF-5 Operable Unit and downstream conditions at the City of Richland, Washington. The scope for this assessment includes only current measured environmental concentrations and current use scenarios. Future environmental concentrations and future land uses are not considered in this assessment.

    The objective of this study was to measure willingness-to-accept (WTA) reductions in risks for HIV and other sexually transmitted infections (STI) using conditional economic incentives (CEI) among men who have sex with men (MSM), including male sex workers (MSW) in Mexico City. A survey experiment was conducted with 1,745 MSM and MSW (18-25 years of age) who received incentive offers to decide first whether to accept monthly prevention talks and STI testing; and then a second set of offers to accept to stay free of STIs (verified by quarterly biological testing). The survey used random-starting-point and iterative offers. WTA was estimated with a maximum likelihood double-bounded dichotomous choice model. The average acceptance probabilities were: 73.9% for the monthly model, and 80.4% for the quarterly model. The incentive-elasticity of participation in the monthly model was 0.222, and it was 0.515 in the quarterly model. For a combination program with monthly prevention talks, and staying free of curable STI, the implied WTA was USD$288 per person per year, but it was lower for MSW: USD$156 per person per year. Thus, some of the populations at highest risk of HIV infection (MSM & MSW) seem well disposed to participate in a CEI program for HIV and STI prevention in Mexico. The average willingness-to-accept estimate is within the range of feasible allocations for prevention in the local context. Given the potential impact, Mexico, a leader in conditional cash transfers for human development and poverty reduction, could extend that successful model for targeted HIV/STI prevention.

    Full Text Available Focussing on the consideration of the multivariate relationship between sport and economics, the present study is based on the sport potential of supporting economic growth through the enhancement of the relatively new domain of “sport entrepreneurship”. The brief revision of the specialized literature regarding the development of sport entrepreneurship in general terms is followed by a series of fundamental factors for the innovative proposal of a sport entrepreneurship index (SEI in the European Union member countries. The methodological issues concerning the structure of the index represent the main novelty aspect of this research, which aims to be a prerequisite of a future thorough analysis regarding the micro- and macro-economic implications of developing a sport entrepreneurship index (SEI in EU countries. The main identified challenge is a scientific one and it resides in the summative assessment of the elements representing entrepreneurship, sport and culture in the SEI, whereas the necessity of determining such an index appears because of economic and social reasons.

    2016-06-01

    Full Text Available The article investigates the state of the credit portfolio of banks in the conditions of instability of the environment and the development of the credit rating of the borrower as a mechanism to prevent the direction of growth of bad debts. The research of the state and dynamics loan portfolio has revealed its sharp deterioration in recent years due to the instability of the external macro environment. The need to reduce the volume of bad debts requires the formation of an adequate mechanism for the borrower's credit rating. Under the mechanism defined in the article the subject-object interaction and providing subsystems have aimed at making management decisions about credit and credit determination capabilities of the enterprise. The authors propose the composition of such a mechanism from the position of a system approach with the subject-object allocation and providing subsystems. As a part of providing credit subsystems the article has allocated a methodological, methodical, information, personnel and organizational support. The article has formed the basic methodological principles of credit rating, namely a comprehensive assessment; the accuracy of the assessment; the progressiveness of the assessment; an objective assessment; professionalism; reality evaluation. Using the proposed credit assessment the mechanism in practice will enhance the effectiveness of the credit relationship between the bank and the borrower. Keywords: credit portfolio; mechanism; creditworthiness assessment; economic instability.

  15. Dynamically linking economic models to ecological condition for coastal zone management: Application to sustainable tourism planning.

    2017-03-01

    While the development of the tourism industry can bring economic benefits to an area, it is important to consider the long-run impact of the industry on a given location. Particularly when the tourism industry relies upon a certain ecological state, those weighing different development options need to consider the long-run impacts of increased tourist numbers upon measures of ecological condition. This paper presents one approach for linking a model of recreational visitor behavior with an ecological model that estimates the impact of the increased visitors upon the environment. Two simulations were run for the model using initial parameters available from survey data and water quality data for beach locations in Croatia. Results suggest that the resilience of a given tourist location to the changes brought by increasing tourism numbers is important in determining its long-run sustainability. Further work should investigate additional model components, including the tourism industry, refinement of the relationships assumed by the model, and application of the proposed model in additional areas.

    Full Text Available Globalization in the economy requires proper management of countries' financial resources as the regulation of international financial market is one of the most important tasks of the successful development of the world economy and individual national economies. The International Monetary Fund since the beginning of its creation was intended to regulate the financial situation in the post-war period in world space. In present conditions of information development of the world economic system the role and importance of international financial institutions are changing. Thus, the policies and activities of the IMF are increasingly criticized, that is substantiated and requires some restructuring and reforming areas of the Fund activity. During the research the basic aspects of IMF activities in 2015 have been analyzed and the suggestions for its further effective development have been presented. In particular, it is advisable to use the specific individual approach to the problems of particular economies and to view the sizes of quotas and their functional purposes that will allow to develop new funding mechanisms that are based on social and ecological needs of society. This, in turn, will reduce the impact of developed countries on the activities of the financial institution

    A new method of thermal and economical optimum design of air conditioning units with vapor compression refrigeration system, is presented. Such a system includes compressor, condenser, evaporator, centrifugal and axial fans. Evaporator and condenser temperatures, their heating surface areas (frontal surface area and number of tubes), centrifugal and axial fan powers, and compressor power are among the design variables. The data provided by manufacturers for fan (volume flow rate versus pressure drop) and compressor power (using evaporator and condenser temperatures) was used to choose these components directly from available data for consumers. To study the performance of the system under various situations, and implementing the optimization procedure, a simulation program including all thermal and geometrical parameters was developed. The objective function for optimization was the total cost per unit cooling load of the system including capital investment for components as well as the required electricity cost. To find the system design parameters, this objective function was minimized by Lagrange multipliers method. The effects of changing the cooling load on optimal design parameters were studied.

    The Energy management systems (EMS) on demand sides are expected as a method to enhance the capability of supply and demand balancing of a power system under the anticipated penetration of renewable energy generation such as Photovoltaics (PV). Elucidation of energy consumption structure in a building is one of important elements for realization of EMS and contributes to the extraction of potential energy saving. In this paper, we propose the estimation method of operating condition of household appliances using circuit current data on an electric distribution board. Circuit current data are broken down by their shape using a self-organization map method and aggregated by appliance based on customers' information of appliance possessed. Proposed method is verified using residential energy consumption measurement survey data.

  3. A Model based Examination of Conditions for Ignition of Turbidity Currents on Slopes

    Mehta, A. J.; Krishna, G.

    2009-12-01

    Turbidity currents form a major mechanism for the movement of sediment in the natural environment. Self-accelerating turbidity currents over continental slopes are of considerable scientific and engineering interest due to their role as agents for submarine sediment transportation from the shelf to the seabed. Such currents are called ignitive provided they eventually reach a catastrophic state as acceleration results in high sediment loads due to erosion of the sloping bed. A numerical model, which treats the fluid and the particles as two separate phases, is applied to investigate the effects of particle size, initial flow friction velocity and mild bed slope on the ignitive condition. Laboratory experimental data have been included as part of the analysis for qualitative comparison purposes. Ignition for the smallest of the three selected sizes (0.21mm) of medium sand typical of Florida beaches was found to depend on the initial conditions at the head of the slope as determined by the pressure gradient. Bed slope seemed to be of secondary importance. For the two sands with larger grain sizes (0.28mm and 0.35mm) the slope was found to play a more important role when compared to the initial pressure gradient. For a given pressure gradient, increasing the slope increased the likelihood of self-acceleration. It is concluded that in general ignition cannot be defined merely in terms of positive values of the velocity gradient and the sediment flux gradient along the slope. Depending on particle size the initial pressure gradient can also play a role. For the selected initial conditions (grain size, pressure gradient and bed slope), out of the 54 combinations tested, all except three satisfied the Knapp-Bagnold criterion for auto-suspension irrespective of whether the turbid current was ignitive or non-ignitive. In all 54 cases the current was found to erode the bed. Further use of the model will require accommodation of wider ranges of sediment size and bed density

    Full Text Available The effects of the economic crisis on European countries has led to serious cuts of the defense budgets and a perceived reduction in the EU’s ability to provide capabilities required by other allies, especially the US. Cooperation, in the form of pooling and sharing may not be an easy and “ready to use” solution to Europe’s defense issues generated by the budget austerity and economic downturn, but it may provide ways to lessen the defense cuts impact on the military capabilities. Nonetheless, the success of the initiative is strongly related to the degree of political and military commitment of the EU countries to put into practice the concept.

    Bickel, Warren K; Moody, Lara; Higgins, Stephen T

    2016-11-01

    Health-related behaviors such as tobacco, alcohol and other substance use, poor diet and physical inactivity, and risky sexual practices are important targets for research and intervention. Health-related behaviors are especially pertinent targets in the United States, which lags behind most other developed nations on common markers of population health. In this essay we examine the application of behavioral economics, a scientific discipline that represents the intersection of economics and psychology, to the study and promotion of health-related behavior change. More specifically, we review what we consider to be some core dimensions of this discipline when applied to the study health-related behavior change. Behavioral economics (1) provides novel conceptual systems to inform scientific understanding of health behaviors, (2) translates scientific understanding into practical and effective behavior-change interventions, (3) leverages varied aspects of behavior change beyond increases or decreases in frequency, (4) recognizes and exploits trans-disease processes and interventions, and (5) leverages technology in efforts to maximize efficacy, cost effectiveness, and reach. These dimensions are overviewed and their implications for the future of the field discussed. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available The Bora wind field is characterised by strong vorticity and divergence. Several numerical experiments, in which an oceanographic model was forced with northeasterly winds having climatological alongshore variability, were performed in order to study the influence of spatial variability in the bora wind field on the surface currents in the northern Adriatic. Numerical model results showed that during bora episodes with lower speeds and fast offshore decay surface currents along transect Rovinj - Po River are predominantly in the downwind direction. On the other hand, during bora episodes with strong intensity and slow offshore decay, a cyclonic gyre due to the pronounced bora alongshore variability is formed in the northernmost part of the Adriatic Sea and the studied transect is influenced by the counter currents. Moreover, bora having a high speed and a short offshore range produces the same effect in the eastern part of the Rovinj - Po River transect as low-speed bora characterised by slow offshore decay. Eulerian current measurements performed in the northern Adriatic during bora episodes characterised by different synoptic conditions supported the numerical model findings. Surface currents during the bora episode of 8-11 February 1984 were directed downwind, whereas during the episode of 12-19 February 1984 they were directed upwind. The first episode was characterised by a deep bora layer with cyclonic activity over the western Mediterranean and Genoa Bay, whereas the second one was accompanied by temperature inversion and a southwesterly tropospheric wind above a shallow bora layer. According to the hydraulic theory developed by Smith (1985, an observed descent of isentropes during the second bora episode led to the stronger acceleration in the bora layer and its larger offshore extent. Different offshore bora decays during studied events were confirmed by a comparison of the wind data originating from the meteorological stations

    Full Text Available The paper analyzes the impact of economic sanctions in general for innovative development of Russia, as well as individual sectors of oil, gas, financial and banking sector. It is shown that the ban on exports to the Russian oil and gas technology has led to the freezing of existing and refusal to enter into new projects. Increased production and export of US oil and gas have led to an increase in excess of the global scope of these types of raw materials and led to long-term downward trend in world energy prices. In recent years there has been a sharp decline in the net inflow of foreign direct investment in Russia, which exacerbates the problem of domestic sources of domestic innovation policy. The effect of sanctions on the development of the Russian economy as a whole and its individual regions is condifered. The paper describes the approaches to the definition of the innovation potential of the Russian region, identified several levels of manifestation of the region's potential and its characteristics, provides a definition of the region's innovation potential, discussed the factors influencing the development of the region's innovative capacity. The current state of the regional innovation system of the Russian Federation is analysed. The paper describes the main tasks of the Russian Federation Innovative Development Strategy for the period up to 2020. The degree of implementation of the Strategy, problems and prospects of realization of the basic provisions of the Strategy, the impact of the implementation of the Strategy on the Russian economy, its position in the index business are analysed in the paper.

    E-waste is one of the fastest-growing waste streams in Iran, owing to an increase in consumption of electrical and electronic equipment. Nevertheless, as is the case in some other countries, E-waste management has not received sufficient attention. For the successful implementation of any waste management plan (including an E-waste management plan), the availability of sufficient and accurate information on the quantities and composition of the waste generated and on current management conditions is a fundamental prerequisite. At present, in Iran, there is no available and accurate information that describes the characteristics and generation rate of E-waste or the actual practice of management and handling of the waste. For this initial study, eight electronic products were selected for the determination of their E-waste generation rate in the country, and two cities, Tehran and Tabriz, were selected for assessment of the current condition of E-waste management. The study found that the amount of E-waste generation in the country for the eight selected electronic items alone was 115,286, 112,914 and 115,151 metric tons in 2008, 2009 and 2010, respectively. Of the types of electronic items included in the study, televisions, with an average of 42.42%, and PCs, with an average of 32.66% accounted for the greatest proportions of the total mass of E-waste generated during 2008-2010. Currently, despite the fact that primary legislation for E-waste management (as part of general waste legislation) exists in Iran, this primary legislation has not yet been implemented. In practical terms, there is no definite policy or plan for the allocation of funds to prepare suitable equipment and facilities for the management and recycling of E-waste at the end of the products' useful life. Proposed improvements in current conditions are identified, first by considering other countries' experiences and then suggesting specific practical policies, rules, and regulations that should be

    The international research community is currently in the process of developing new scenarios for climate change research. One component of these scenarios are the Shared Socio-economic Pathways (SSPs), which describe a set of possible future socioeconomic conditions. These are presented in narrative storylines with associated quantitative drivers. The core quantitative drivers include total population, average GDP per capita, educational attainment, and urbanization at the global, regional, and national levels. At the same time there have been calls, particularly by the IAV community, for the SSPs to include additional quantitative information on other key social factors, such as income inequality, governance, health, and access to key infrastructures, which are discussed in the narratives. The International Futures system (IFs), based at the Pardee Center at the University of Denver, is able to provide forecasts of many of these indicators. IFs cannot use the SSP drivers as exogenous inputs, but we are able to create development pathways that closely reproduce the core quantitative drivers defined by the different SSPs, as well as incorporating assumptions on other key driving factors described in the qualitative narratives. In this paper, we present forecasts for additional quantitative indicators based upon the implementation of the SSP development pathways in IFs. These results will be of value to many researchers.

    Global climate change is predicted to increase temperatures, alter geographical patterns of rainfall and increase the frequency of extreme climatic events. Such changes are likely to alter the timing and magnitude of drought stresses experienced by crops. This study used new developments in the classification of crop water stress to first characterize the typology and frequency of drought-stress patterns experienced by European maize crops and their associated distributions of grain yield, and second determine the influence of the breeding traits anthesis-silking synchrony, maturity and kernel number on yield in different drought-stress scenarios, under current and future climates. Under historical conditions, a low-stress scenario occurred most frequently (ca. 40%), and three other stress types exposing crops to late-season stresses each occurred in ca. 20% of cases. A key revelation shown was that the four patterns will also be the most dominant stress patterns under 2050 conditions. Future frequencies of low drought stress were reduced by ca. 15%, and those of severe water deficit during grain filling increased from 18% to 25%. Despite this, effects of elevated CO2 on crop growth moderated detrimental effects of climate change on yield. Increasing anthesis-silking synchrony had the greatest effect on yield in low drought-stress seasonal patterns, whereas earlier maturity had the greatest effect in crops exposed to severe early-terminal drought stress. Segregating drought-stress patterns into key groups allowed greater insight into the effects of trait perturbation on crop yield under different weather conditions. We demonstrate that for crops exposed to the same drought-stress pattern, trait perturbation under current climates will have a similar impact on yield as that expected in future, even though the frequencies of severe drought stress will increase in future. These results have important ramifications for breeding of maize and have implications for

    Full Text Available Governments sell bonds to finance their budget. The investors willing to buy government bonds because of the yield they will get, but on the other hand if government bond yields is  too high it would burden the state in paying the interest due. Various studies have been done to find the variables that affect government bond yield significantly, such as exchange rate, inflation rate, interest rate, and oil price. This study found two more variables namely consumer expectations index and the economic conditions index to complement the variables that have been discovered. Those two variables are used as a proxy of economic stability of a country, the increase of those variables represent the increase of economic stability and will reduce the level of risk and lowering the yield that investors demand. This research use descriptive method and explanatory study with secondary data using multivariate regression equation model. The results shown consumer expectation index and economic condition index have significant effect on Indonesian Government Bond yield. To keep consumer expectation index and economic condition index increase government should give a positive signal and a sense of security to investor.

    Full Text Available This study explored a longitudinal data set of 6875 British adults examining the effects of parental social status (measured at birth, cognitive ability (at age 11 yrs, personality traits, education and occupational attainment on physical health and functioning (all measured at age 50 yrs, after taking account of current health conditions (number of illness. Correlation analysis showed that parental social class, childhood cognitive ability, education and occupation, and two personality traits (Emotional Stability/Neuroticism, and Conscientiousness were all significantly associated with adult physical health variables. Structural equation modelling showed that health conditions and personality traits were significantly, and inversely, associated with physical health (indicated by good daily physical functioning, relative absence of pain, perceived health, and low level of limitations at work due to physical health. Parental social status, childhood intelligence, educational and occupational attainment were all modestly, but significantly and directly, associated with adult physical health. The effect of childhood intelligence on adult physical health was, in part, mediated through Emotional Stability and Conscientiousness. After controlling for health conditions Emotional Stability was the strongest predictor of physical health. Implications and limitations are discussed.

    Full Text Available There is a close link between economic performance and increasing internationalization of SMEs. International activities increase competitiveness and ensure long-term development of enterprises. However, European SMEs still depend largely on their internal markets, notwithstanding the opportunities created to the single market and globalization in general. A study realized in 2009 by the European Commission reveals that internationalization creates more jobs: SMEs active in foreign markets reported an increase in employment by 7% compared to only 1% free activities for SMEs international. Internationalized SMEs are more innovative: 26% of SMEs have introduced internationally active products or services that were new to the sector in their country of origin.

  1. Effect of multiple-feedstock strategy on the economic and environmental performance of thermochemical ethanol production under extreme weather conditions

    2011-01-01

    Current US transportation sector mainly relies on liquid hydrocarbons derived from petroleum and about 60% of the petroleum consumed is from areas where supply may be disturbed by regional instability. This has led to serious concerns on energy security and global warming. To address these issues, numerous alternative energy carriers have been proposed. Among them, second generation biofuel is one of the most promising technologies. Gasification-based thermochemical conversion will bring flexibility to both feedstock and production sides of a plant, thus presents an attractive technical route to address both the energy security and global warming concerns. In this paper, thermochemical ethanol production using multiple-feedstock (corn stover, municipal solid waste, and wood chips) is simulated using Aspen Plus and compared with the single-feedstock scenario, in terms of economic performances, life cycle greenhouse gas (GHG) emissions and survivability under extreme weather conditions. For a hypothetical facility in southwest Indiana it is found that multiple-feedstock strategy improves the net present value by 18% compared to single-feedstock strategy. This margin is increased to 57% when effects of extreme weather conditions on feedstock supply are considered. Moreover, multiple-feedstock fuel plant has no potential risk of bankruptcy during the payback period, while single-feedstock fuel plant has a 75% chance of bankruptcy. Although the multiple-feedstock strategy has 26% more GHG emission per liter of ethanol produced than the single-feedstock strategy, the trend is reversed if feedstock supply disruption is taken into account. Thus the idea of multiple-feedstock strategy is proposed to the future thermo chemical biofuel plants.

  2. Current trends in Canadian health care: myths and misconceptions in health economics.

    This paper is concerned with the economic aspects of the trends in Canadian health care. Various myths and misconceptions abound regarding the applicability of economics to behaviour in the health care industry as well as to the interpretation of recent trends. Both issues are examined in this paper. While most discussions regarding health care trends begin with the share of health expenditures in Gross National Product, I propose an alternative share that adjusts for cyclical variations in both unemployment and labour force participation. Using this measure, I show that the "real" growth of resources devoted to the health care industry is much larger than that obtained with conventional measures, and that the difference in growth rates between Canada and the U.S. is narrowed considerably. The paper outlines and disputes the validity of three public health policy propositions. First, it is not empirically valid to say that the introduction of universal medical insurance in Canada successfully contained the growth in the share of society's resources devoted to the health care industry. Second, it is not correct to argue that the change in the federal funding for hospital and medical care in 1977 was a "fiscal non-event". And finally, the proposed "equity" funding formula for Ontario hospitals is unlikely to contain costs and will potentially skew hospitals towards the provision of complex forms of care instead of cost-effective community-based alternatives.

    Background: The mixed empirical evidence about employment conditions (i.e., permanent vs. temporary job, full-time vs. part-time job) as well as unemployment has motivated the development of conceptual models with the aim of assessing the pathways leading to effects of employment status on health. Alongside physically and psychologically riskier working conditions, one channel stems in the possibly severe economic deprivation faced by temporary workers. We investigate whether economic deprivation is able to partly capture the effect of employment status on Self-evaluated Health Status (SHS). Methods: Our analysis is based on the European Union Statistics on Income and Living Conditions (EU-SILC) survey, for a balanced sample from 26 countries from 2009 to 2012. We estimate a correlated random-effects logit model for the SHS that accounts for the ordered nature of the dependent variable and the longitudinal structure of the data. Results and Discussion: Material deprivation and economic strain are able to partly account for the negative effects on SHS from precarious and part-time employment as well as from unemployment that, however, exhibits a significant independent negative association with SHS. Conclusions: Some of the indicators used to proxy economic deprivation are significant predictors of SHS and their correlation with the employment condition is such that it should not be neglected in empirical analysis, when available and further to the monetary income.

Collection of the ichthyological material was carried out in the lower Dnieper River from commercial fishing gears, including beach seines, drag seines, fyke-nets. Field, laboratory processing of samples and mathematical analysis of the obtained results were carried out according to generally accepted methods and guidelines with some assumptions regarding the duration of pike fattening directly in the lower Dnieper River. Findings. Recent years, there is an increase in the specific weight of younger age groups in the pike stock in the lower Dnieper River. Analysis of linear growth indicates on satisfactory environmental conditions for pike. Current commercial contingent of pike is based on size classes of 46–50 cm versus 22–32 cm in the first half of the last century. Reproductive properties of pike, in particular fecundity, egg size and maturity coefficients did not virtually change compared to those of the last century. Depending on linear sizes, the absolute fecundity is 32.3–155.8 thousand eggs and the maturation coefficient is 11.1–15.7%. Morphologic variability of pike in the lower Dnieper River during the period from 1980s to the present time was observed for plastic features, which characterized fin sizes. Sexual dimorphism in current conditions was observed only for maximum body depth. No significant differences for other plastic features between males and females of pike in the lower Dnieper River. Originality. The data on biological characteristics of pike stock from the lower Dnieper River have been updated. Current fecundity of females of different size groups recorded in commercial catches was been determined.

    2017-11-01

    Operation and maintenance (O&M) of wind turbines is recently becoming the spotlight in the wind energy sector. While wind turbine power capacities continue to increase and new offshore developments are being installed, O&M costs keep raising. With the objective of reducing such costs, the new trends are moving from corrective and preventive maintenance toward predictive actions. In this scenario, condition monitoring (CM) has been identified as the key to achieve this goal. The induction generator of a wind turbine is a major contributor to failure rates and downtime where doubly-fed induction generators (DFIG) are the dominant technology employed in variable speed wind turbines. The current work presents the analysis of an in-service DFIG. A one-year measurement campaign has been used to perform the study. Several signal processing techniques have been applied and the optimal method for CM has been identified. A diagnosis has been reached, the DFIG under study shows potential gearbox damage.

    The effects of heating conditions on critical current properties and microstructures of undoped MgB 2 bulks were systematically studied. Strong correlation was observed between J c and microstructures. The network structure with an excellent inter-grain connectivity of MgB 2 grains contributed to high-J c under low magnetic fields, and small grain size of MgB 2 enhanced the grain boundary flux pinning. Long time heating at low temperatures below the melting point of magnesium was discovered to be most effective for synthesis of MgB 2 bulks having strongly connected MgB 2 network structure with small grains. The sample heated at 550 deg. C for 1200 h recorded a high-J c of 4.02 x 10 5 A cm -2 at 20 K in self-field, while high-temperature and long time heating brought a significant grain growth which resulted in low J c

  13. Sarcopenia: An Undiagnosed Condition in Older Adults. Current Consensus Definition: Prevalence, Etiology, and Consequences

    2012-01-01

    Sarcopenia, the age associated loss of skeletal muscle mass and function, has considerable societal consequences for the development of frailty, disability and health care planning. A group of geriatricians and scientists from academia and industry met in Rome, Italy on November 18, 2009 to arrive at a consensus definition of sarcopenia. The current consensus definition was approved unanimously by the meeting participants and is as follows: Sarcopenia is defined as the age-associated loss of skeletal muscle mass and function. The causes of sarcopenia are multi-factorial and can include disuse, altered endocrine function, chronic diseases, inflammation, insulin resistance, and nutritional deficiencies. While cachexia may be a component of sarcopenia, the two conditions are not the same. The diagnosis of sarcopenia should be considered in all older patients who present with observed declines in physical function, strength, or overall health. Sarcopenia should specifically be considered in patients who are bedridden, cannot independently rise from a chair, or who have a measured gait speed less that 1.0 m·s−1. Patients who meet these criteria should further undergo body composition assessment using dual energy x-ray absorptiometry (DXA) with sarcopenia being defined using currently validated definitions. A diagnosis of sarcopenia is consistent with a gait speed of less than 1 m·s−1 and an objectively measured low muscle mass (eg: appendicular mass relative to ht2 that is ≤ 7.23 kg/ m2 in men ≤ 5.67 kg/ m2 in men). Sarcopenia is a highly prevalent condition in older persons that leads to disability, hospitalization and death. PMID:21527165

    Vibrio cholerae is a globally distributed water-borne pathogen that causes severe diarrheal disease and mortality, with current outbreaks as part of the seventh pandemic. Further understanding of the role of environmental factors in potential pathogen distribution and corresponding V. cholerae disease transmission over time and space is urgently needed to target surveillance of cholera and other climate and water-sensitive diseases. We used an ecological niche model (ENM) to identify environmental variables associated with V. cholerae presence in marine environments, to project a global model of V. cholerae distribution in ocean waters under current and future climate scenarios. We generated an ENM using published reports of V. cholerae in seawater and freely available remotely sensed imagery. Models indicated that factors associated with V. cholerae presence included chlorophyll-a, pH, and sea surface temperature (SST), with chlorophyll-a demonstrating the greatest explanatory power from variables selected for model calibration. We identified specific geographic areas for potential V. cholerae distribution. Coastal Bangladesh, where cholera is endemic, was found to be environmentally similar to coastal areas in Latin America. In a conservative climate change scenario, we observed a predicted increase in areas with environmental conditions suitable for V. cholerae. Findings highlight the potential for vulnerability maps to inform cholera surveillance, early warning systems, and disease prevention and control. Copyright © 2015 The Authors.

    The plasma parameters such as electron distribution function and electron density of three atmospheric-pressure transient discharges namely filamentary and homogeneous dielectric barrier discharges in air, and the spark discharge of an argon plasma coagulation (APC) system are determined. A combination of numerical simulation as well as diagnostic methods including current measurement and optical emission spectroscopy (OES) based on nitrogen emissions is used. The applied methods supplement each other and resolve problems, which arise when these methods are used individually. Nitrogen is used as a sensor gas and is admixed in low amount to argon for characterizing the APC discharge. Both direct and stepwise electron-impact excitation of nitrogen emissions are included in the plasma-chemical model applied for characterization of these transient discharges using OES where ambiguity arises in the determination of plasma parameters under specific discharge conditions. It is shown that the measured current solves this problem by providing additional information useful for the determination of discharge-specific plasma parameters. (paper)

    The Sustained Spheromak Physics Experiment (SSPX) was a toroidal magnetic-confinement device without toroidal magnetic-field coils or a central transformer but which generated core-plasma currents by dynamo processes driven by coaxial plasma-gun injection into a flux-conserving vessel. Record electron temperatures in a spheromak (Te˜500eV) were achieved, and final results of the SSPX program were reported in [1]. Plasma density, which depended strongly on wall conditions, was an important parameter in SSPX. It was observed that density rises with Igun and that confinement improved as the density was lowered. Shortly after the last experiments, a new feature was added to the Corsica code's solver used to reconstruct SSPX equilibria. Motivated by n=0 fields observed in NIMROD simulations of SSPX, an insulating boundary condition was implemented at the plasma-gun gap. Using this option we will perform new reconstructions of SSPX equilibria and look for correlations between the location of the separatrix (which moves up the gun wall and onto the insulating gap as Igun increases) and plasma density and magnetic-flux amplification [2].[4pt] [1] H.

    A number of studies have been concerned with the evaporation rates under martian conditions in order to place limits on the possible survival time of both liquid water and ice exposed on the surface of Mars. Such studies also aid in assessing the efficacy of an overlying layer of dust or loose regolith material in providing a barrier to free evaporation and thus prolong the lifetime of water in locations where its availability to putative living organisms would be significant. A better quantitative understanding of the effects of phase changes of water in the near surface environment would also aid the evaluation of the possible role of water in the formation of currently observed features, such as gullies in cliff walls and relatively short-term changes in the albedo of small surface areas ('dark stains'). Laboratory measurements aimed at refinement of our knowledge of these values are described here. The establishment of accurate values for evaporation rates and their dependence on the physical conditions of temperature, pressure and energy input, is an important benchmark for the further investigation of the efficacy of barriers to free evaporation in providing a prolonged period of survival of the water, particularly as a liquid.

    2017-04-01

    Although ocean surface waves are known to play an important role in the momentum and other scalar transfer between the atmosphere and the ocean, most operational numerical models do not explicitly include the terms of wave-current interaction. In this work, a numerical analysis about the relative importance of the processes associated with the wave-current interaction under strong off-shore wind conditions in Gulf of Tehuantepec (the southern Mexican Pacific) was carried out. The numerical system includes the spectral wave model WAM and the 3D hydrodynamic model POLCOMS, with the vertical turbulent mixing parametrized by the kappa-epsilon closure model. The coupling methodology is based on the vortex-force formalism. The hydrodynamic model was forced at the open boundaries using the HYCOM database and the wave model was forced at the open boundaries by remote waves from the southern Pacific. The atmospheric forcing for both models was provided by a local implementation of the WRF model, forced at the open boundaries using the CFSR database. The preliminary analysis of the model results indicates an effect of currents on the propagation of the swell throughout the study area. The Stokes-Coriolis term have an impact on the transient Ekman transport by modifying the Ekman spiral, while the Stokes drift has an effect on the momentum advection and the production of TKE, where the later induces a deepening of the mixing layer. This study is carried out in the framework of the project CONACYT CB-2015-01 255377 and RugDiSMar Project (CONACYT 155793).

    Full Text Available This article examines existing techniques and proposes its own for analyzing the attractiveness of international commodity markets in light of the globalization of world economic processes. Taking into account the supranational nature of the world economic environment when examining categories in the attractiveness of international commodity markets, the author introduces a multilevel system of indicators: market attractiveness at the mega-level – global level; market attractiveness at the macro-level national level; market attractiveness at the mezo-level – level of an individual sector. The attractiveness of international commodity markets is considered to be the degree of conformity between market environment factors and the mega-, macro- and mezo-levels of the economic interests of enterprises concerning the entry into and strategies for their activity on the international commodity markets in the short-, medium- and long-term. The author designs a stage-by-stage technique for strategically analyzing the attractiveness of international commodity markets in order to frame efficient market strategies of enterprises. Relying on the proposed techniques, she rates the integrated indicators of market accessibility and the possibility of realizing the economic interests of enterprises in target markets, bringing the index data into a matrix of «market accessibility – opportunity for realizing the economic interests of enterprises.» The analysis of a country’s position in the matrix makes it possible to frame efficient market strategies for enterprises.

    Air pollution continues to be a problem in the urban environment. A range of different pollutant mitigation strategies that promote dispersion and deposition exist, but there is little evidence with respect to their comparative performance from both an environmental and economic perspective. This paper focuses on examining different NO 2 mitigation strategies such as trees, buildings facades coated with photocatalytic paint and solid barriers in Oxford Street in London. The case study findings will support ranking the environmental and economic impacts of these different strategies to improve personal exposure conditions on the footpath and on the road in a real urban street canyon. CFD simulations of airflow and NO 2 dispersion in Oxford Street in London were undertaken using the OpenFOAM software platform with the k-ε model, taking into account local prevailing wind conditions. Trees are shown to be the most cost-effective strategy, with a small reduction in NO 2 concentrations of up to 0.7% on the road. However, solid barriers with and without the application of photocatalytic paint and an innovative material (20 times more expensive than trees) can improve air quality on the footpaths more substantially, up to 7.4%, yet this has a significant detrimental impact on NO 2 concentrations (≤23.8%) on the road. Photocatalytic paint on building surfaces presented a minimal environmental reductions (1.2%) and economic (>100 times more expensive than trees) mitigation strategy. The findings recognised the differences between footpath and road concentrations occurred and that a focused examination of three pollution hotspots can provide more cost effective pollution mitigation. This study considers how a number of pollutant mitigation measures can be applied in a single street canyon and demonstrates the strengths and weaknesses of these strategies from economic and environmental perspectives. Further research is required to extrapolate the findings presented here to

    The National Renewable Energy Laboratory (NREL) has undertaken a complete review and update of the process design and economic model for the biomass-to-ethanol enzymatic based process. The process design includes the core technologies being researched by the U.S. Department of Energy (DOE): prehydrolysis, simultaneous saccharification and co-fermentation, and cellulase enzyme production. In addition, all ancillary areas--feed handling, product recovery and purification, wastewater treatment lignin burner and boiler--turbogenerator, and utilities--are included. NREL engaged Delta-T Corporation to assist in the process design evaluation, equipment costing, and overall plant integration. The process design and costing for the lignin burner and boiler turbogenerator has been reviewed by Reaction Engineering Inc. and the wastewater treatment by Merrick and Company. An overview of both reviews is included here. The purpose of this update was to ensure that the process design and equipment costs were reasonable and consistent with good engineering practice for plants of this type using available technical data. This work has resulted in an economic model that can be used to predict the cost of producing ethanol from cellulosic biomass using this technology if a plant were to be built in the next few years. The model was also extended using technology improvements that are expected to be developed based on the current DOE research plan. Future process designs and cost estimates are given for the years 2005, 2010, and 2015.

    In Belgium, the electrical engineers have to periodically establish, for the government, a national equipment plan which justifies the provided investments for a period of 10 years after the publication of the plan. The elaborated development is appreciated by four criteria: the environmental impact, the park workableness, its economic robustness and the production saving. In order to estimate this last criteria, the method used is called of the 'leveled discounted electricity generation costs'. It is recommended and used by international agencies such as the IAEA, OECD, UNIPE. The comparisons between the nuclear production cost, carried out during two successive equipment plans (1988 and 1994), show the evolution of technologies, costs and forecasts of these last ten years. In particular, the last valuation has to take into account uncertainty ranges of which the importance prevents to draw a definitive conclusion about the production mean which will be the most inexpensive in the future: competition is open between the different types of factories and fuels. The recent national equipment plan (1995-2005) proposes to cover 53% of the additional needs by gas combined-cycle power plants, 29% by coal combined-cycle power plants and 18% by the Belgian interest in French B. Chooz nuclear powered plants. The nuclear choice is open for the future. (O.M.)

    This second edition of the Biomass Energy Success Stories covers a wide range of examples of organizations which have experienced economic benefits by substituting renewable biomass energy for non-renewable fossil fuels. In addition to the broader spectrum of industry seen to be pursuing this approach, the cases illustrate a move towards innovative and technologically more sophisticated approaches. For example, the Quebec Community's thermal accumulator acts as a buffer to accommodate the variable fuel value of boiler fuel consisting of unpredictable residues of variable moisture content. By this innovative approach, the quality of steam to its year-round customer can be held within the contractual limits. Another unique development appears in the use of the LAMB-CARGATE wet cell burner which is able to cope with wood residue fuels containing up to 70% moisture. Two of the more interesting and promising developments in the race to substitute renewable energy for fossil fuels are Fluidized Bed and Fuel-alcohol on-farm distilleries. For this reason appendices are included giving some useful insights concerning them.

    Full Text Available Pakistan is currently facing physical and economic water scarcity issues that are further complicated by the rapid increase in its population and by climate change. Many studies have focused on the physical water scarcity using hydrological modeling and the measurement of the impact of climate change on water resources in the Upper Indus Basin (UIB. However, few studies have concentrated on the importance of the economic water scarcity, that is, the water management issue under the looming impacts of climate change and the population explosion of Pakistan. The purpose of this study is to develop a management strategy which helps to achieve water security and sustainability in the Upper Indus Basin (UIB with the help of different socio-economic and climate change scenarios using WEAP (Water Evaluation and Planning modeling. The streamflow data of five sub-basins (Gilgit, Hunza, Shigar, Shyok, and Astore and the entire Upper Indus Basin (UIB were calibrated (2006–2010 and validated (2011–2014 in the WEAP model. The coefficient of determination and Nash Sutcliffe values for the calibration period ranged from 0.81–0.96. The coefficient of determination and the Nash Sutcliffe values for the validation period ranged from 0.85–0.94. After the development of the WEAP model, the analysis of the unmet water demand and percent coverage of the water demand for the period of 2006–2050 was computed. Different scenarios were generated for external driving factors (population growth, urbanization, and living standards and the impact of climate change to evaluate their effect on the current water supply system. The results indicated that the future unmet water demand is likely to reach 134 million cubic meters (mcm by the year 2050 and that the external driving factors are putting more pressure on the supply service. This study further explores the importance of proposed dams (likely to be built until 2025 by WAPDA (Water and Power Development

  11. Three Gorges Reservoir Area: soil erosion under natural condition vs. soil erosion under current land use

    2010-05-01

    Apparently, the current most prominent human-induced example for large scale environmental impact is the Three Gorges Dam in China. The flooding alongside the Yangtze River, and its tributaries results in a vast loss of settlement and farmland area with productive, fertile valley soils. Due to the associated high land use dynamic on uphill-sites, the soil resources are underlying high land use pressure. Within our study, the soil erosion under natural conditions is compared to the soil erosion under current land use after the impoundment. Both were modeled using the empirical Universal Soil Loss Equation (USLE) which is able to predict long-term annual soil loss with limited data. The database consists of digital terrain data (45 m resolution DEM, erosive slope length based on Monte-Carlo-Aggregation according to Behrens et al. (2008)), field investigations of recent erosion forms, and literature studies. The natural disposition to soil erosion was calculated considering the USLE factors R, S, and K. The soil erosion under current land use was calculated taking into account all USLE factors. The study area is the catchment of the Xiangxi River in the Three Gorges Reservoir area. Within the Xiangxi Catchment (3,200 km²) the highly dynamic backwater area (580 km²), and two micro-scale study sites (Xiangjiaba with 2.8 km², and Quyuan with 88 km²) are considered more detailed as they are directly affected by the river impoundment. Central features of the Xiangxi Catchment are the subtropical monsoon climate, an extremely steep sloping relief (mean slope angle 39°, SD 22.8°) artificially fractured by farmland terraces, and a high soil erodibility (mean K factor 0.37, SD 0.13). On the catchment scale the natural disposition to soil erosion makes up to mean 518.0 t ha-1 a-1. The maximum potential soil loss of 1,730.1 t ha-1 a-1 under natural conditions is reached in the Quyuan site (mean 635.8 t ha-1 a-1) within the backwater area (mean 582.9 t ha-1 a-1). In the

    Generation and amplification mechanisms of ocean waves are well understood under constant wind speed or limited fetch conditions. Under these situations, the momentum and energy transfers from air to water are also quite well known. However during the wind field evolution over the ocean, we may observe sometime high wind acceleration/deceleration situations (e.g. Mexican Tehuano or Mediterranean Mistral wind systems). The evolution of wave systems under these conditions is not well understood. The purpose of these laboratory experiments is to better understand the early stages of water-waves and surface-drift currents under non-stationary wind conditions and to determine the balance between transfers creating waves and surface currents during non-equilibrium situations. The experiments were conducted in the Institut Pythéas wind-wave facility in Marseille-France. The wave tank is 40 m long, 2.7 m wide and 1 m deep. The air section is 50 m long, 3 m wide and 1.8 m height. We used 11 different resistive wave-gauges located along the tank. The momentum fluxes in the air column were estimated from single and X hot-film anemometer measurements. The sampling frequency for wind velocity and surface displacement measurements was 256 Hz. Water-current measurements were performed with a profiling velocimeter. This device measures the first 3.5 cm of the water column with a frequency rate of 100Hz. During the experiments, the wind intensity was abruptly modified with a constant acceleration and deceleration over time. We observed that wind drag coefficient values for accelerated wind periods are lower than the ones reported in previous studies for constant wind speed (Large and Pond 1981; Ocampo-Torres et al. 2010; Smith 1980; Yelland and Taylor 1996). This is probably because the turbulent boundary layer is not completely developed during the increasing-wind sequence. As it was reported in some theoretical studies (Miles 1957; Phillips 1957; Kahma and Donelan 1988), we

    Full Text Available The purpose of this study is to provide the analytical background of North Korea's trade expansion with Western countries in the early 1970's and examine in depth the resulting impacts on the North Korean economy. Indeed, this study explores the implications of the mechanism and consequences of North Korea's increased trade with Western countries in the 1970's for the current situation of the country's trade expansion based on the rapid increase in imports and large trade deficit. As a result of researching North Korea's economic trajectory during the 1970's within this focus, this study asserts that, despite some positive aspects, North Korea's rapid increase of foreign trade in recent years possesses the immanent possibility of generating serious obstacles to the process of economic recovery. In this vein, this paper intends to explore some policy options North Korea should choose in order to create conditions conducive to economic rehabilitation and prevent the recurrence of similar situation as experienced in the 1970's.

    CSP and PV technologies represent energy sources with large potentials. We present cost-supply curves for both technologies using a consistent methodology for 26 regions, based on geoexplicit information on solar radiation, land cover type and slope, exploring individual potential and interdependencies. For present day, both CSP and PV supply curves start at $0.18/kWh, in North Africa, South America, and Australia. Applying accepted learning rates to official capacity targets, we project prices to drop to $0.11/kWh for both technologies by 2050. In an alternative “fast-learning” scenario, generation costs drop to $0.06–0.07/kWh for CSP, and $0.09/kWh for PV. Competition between them for best areas is explored along with sensitivities of their techno-economic potentials to land use restrictions and land cover type. CSP was found to be more competitive in desert sites with highest direct solar radiation. PV was a clear winner in humid tropical regions, and temperate northern hemisphere. Elsewhere, no clear winner emerged, highlighting the importance of competition in assessments of potentials. Our results show there is ample potential globally for both technologies even accounting for land use restrictions, but stronger support for RD&D and higher investments are needed to make CSP and PV cost-competitive with established power technologies by 2050. - Highlights: • A consistent assessment of global potential for CSP and PV, with cost-supply curves for 26 regions. • Combined global CSP and PV potential below US$0.35/kWh estimated at 135,128 TWh per year. • Competition for same land-based solar resource implies that potentials cannot be added. • Attractive areas are MENA, Northern Chile, Australia, China and Southwestern USA. • Costs are projected to go down over time, reaching US$0.06–0.11/KWh for attractive sites in 2050

  18. "Holistic" care for stroke in the context of the current health care bureaucracy and economic reality.

    Science.gov (United States)

    Teasell, Robert

    2011-01-01

    The target paper by Sharon Kaufman argues that modern Western health care delivery is characterized by "the coexistence of two conflicting conceptual frameworks," namely a "holistic" approach that attempts to take into account the cultural and personal needs of the individual stroke patient and "medicalization" that attempts to reduce people and their illnesses to biological processes which can then be treated through "evidence-based" biomedical approaches. Although it is true that these 2 approaches often coexist and are sometimes in conflict, it would be misleading to see these as totally dichotomous. Patients want holistic approaches less than we give them credit for, and physicians are less mechanical than such a dichotomy would suggest. In fact, more often than not, patients and their health care providers combine to engender unrealistic expectations about what modern medicine is actually able to accomplish. When the system breaks down, as it often does in stroke (with a patient who is still left with a significant impairment an disability as well as unresolved concerns and issues related to his or her often catastrophic loss of function), there is a certain inevitable backlash. However, this tension between holistic expectations and the medical response is overshadowed by institutional constraints on clinical decision making that are designed to manage or balance expectations of both patients and health care professionals with economic realities and, in doing so, often run rough-shod over the "holistic" needs of patients and their families as well as health care providers' attempts to manage disease and disability within a medical framework.

    Aging process is characterized by difficulties in ensuring balance control, especially in conditions of reduced or conflicting sensory information, leading to an increased risk of falling. Conversely, the practise of physical activities (PA) has been recognized as a good approach to improve the quality of balance control. This study aimed to investigate the influence of current and/or past PA on balance-related neurosensorial organization in older adults on the maintenance of the upright stance, especially during sensory conflicting situations. Postural control was evaluated by means of the Sensory Organization Test on 130 healthy noninstitutionalized volunteers aged over 65, split into four groups according to the presence or absence of PA before or after retirement. Subjects who practised PA for a long time (Gr1) and subjects who started PA after retirement (Gr2) displayed the best postural performances and better managed sensory conflicting situations compared to subjects who had stopped PA for many years (Gr3) and subjects who had never practised PA (Gr4). Multiple regression analyses revealed that current PA was the major determinant for postural parameters during sensorial conflict compared to age, gender, body mass index and past PA. Regular PA, even when started late in life, allows appropriate reorganization of the different components of postural control during sensory conflicting situations. Indeed, active subjects were more able to compensate for suppressed or perturbed sensory information by an increased usage of another referential and so to correct their posture by adopting a more appropriate balance strategy. Thus, PA counteracts the age-related decline of postural control and could consequently reduce the risk of falling.

    Full Text Available Introduction. The number, range, and diversity of events with a character of festivals have been growing in the Lublin Region over the last several years. The events are organised by various entities and institutions. Information about them is largely dispersed. No study has been conducted so far determining the spatial distribution of festivals at the regional scale, and analysing their offer in the context of possibilities of development of festival tourism. Therefore, a study in the scope was undertaken with consideration of the cultural conditionings of some of the events. Material and methods. In periods from July to December 2010 and from September to December 2013, secondary information was analysed (statistics, records, and scientific studies, and original material was collected (field inventory, interview, and diagnostic survey regarding the current condition of festival tourism in the Lublin Region. Results. The collected data on festival tourism offers suggest that the number of festivals in the Lublin Region has been continuously increasing from year to year. According to the obtained data, festivals with a duration of 3 and 5 days are dominant. The majority of festivals are held in summer months, usually on weekends. Music and interdisciplinary festivals with international, national, and regional range are prevalent. Some of them already have a history of 47 years. The analysis of the spatial distribution of the festivals subject to the inventory suggests that the majority of them are organised in the largest cities of the region, namely Lublin, Zamośæ, and Kazimierz Dolny. Conclusions. Due to the very diverse offer of festivals, and the manner of their promotion, they play an important role in the promotion of the Lublin Region. The offer, spatial distribution, and dynamics in the scope of organisation of festivals provide good perspectives for the development of festival tourism in the Lublin Region.

    Full Text Available Human resource is currently the most valuable wealth of a nation and carries with it the most important principle of development; it is about innovation, without which competitiveness is unthinkable. Romania is part of the “catching–up” group of countries in innovation. In order to assume new responsibilities and to prepare for the competition with other European countries and not only, manyreforms and changes is necessary. Assuming these premises, in this paper, our intention is to analyze the situation of innovation at EUlevel and to see at what chapters our authorities must to work harder to equalize the other states from the Western European states. This thing is absolutely necessary because, now, when our country makes part from EU, it needs to invest in human resources through better education, skills and support.

    Full Text Available Health care occupies a distinct niche in an economy struggling to recover from recession. Professions related to the care of patients are thought to be relatively resistant to downturns, and thus become attractive to students typically drawn to more lucrative pursuits. Currently, a higher profile for clinical laboratory technology among college students and those considering career change results in larger and better prepared applicant pools. However, after decades of contraction marked by closing of programs, prospective students encounter an educational system without the capacity or vigor to meet their needs. Here discussed are some principles and proposals to allow universities, partnering with health-care providers, government agencies, and other stakeholders to develop new programs, or reenergize existing ones to serve our students and patients. Principles include academic rigor in biomedical and clinical science, multiple points of entry for students, flexibility in format, cost effectiveness, career ladders and robust partnerships.

    The aim of this study was to estimate the economic impact of mastitis at the herd level and the weight (percent) of the components of this impact in a Holstein dairy herd under tropical conditions. Three estimates of the economic impact of mastitis were performed. In estimates 1 and 2 the real production and economic indices from February 2011 to January 2012 were considered. In the estimate 1, indices for mastitis classified as ideal were considered, whereas in the estimate 2, the mastitis indices used were those recorded at the farm and at Holstein Cattle Association of Minas Gerais State database (real indices). Ideal mastitis indices were bulk milk somatic cell counts less than 250,000 cells/mL, incidence of clinical mastitis less than 25 cases/100 cows/year, number of culls due to udder health problems less than 5% and the percentage of cows with somatic cell counts greater than 200,000 cells/mL less than 20%. Considering the ideal indices of mastitis, the economic impact was US$19,132.35. The three main components of the economic impact were culling cows (39.4%) and the reduction in milk production due to subclinical and clinical mastitis (32.3% and 18.2%, respectively). Estimate 2 using real mastitis indices showed an economic impact of US$61,623.13 and the reduction in milk production due to mastitis (77.7%) and milk disposal (14.0%) were the most relevant components. The real impact of culling cows was approximately 16 times less than the weight that was considered ideal, indicating that this procedure could have been more frequently adopted. The reduction in milk production was 27.2% higher than the reduction in Estimate 1, indicating a need to control and prevent mastitis. The estimate 3 considered the same indices as estimate 2, but for the period from February 2012 to January 2013. Its economic impact was US$91,552.69. During this period, 161 treatments of cows with an intramammary antibiotic were performed to eliminate Streptococcus agalactiae, and

    This study investigated the current situation and environmental conditions of green mussel Perna viridis farming in Surat Thani, Phetchaburi and Samut Prakan provinces where were located in the gulf of Thailand. Samples were collected during April, August and November in 2014. Based on the results of this study, there were three major types of mussel culture patterns in Thailand: bouchot culture, longline culture (rope culture), and raft culture. Mussel farmers encountered problems on decreasing of larvae mussel in the water column, water quality degradation, high production cost and farmer’s lack of negotiation power to control the price. The water quality of the mussel farms, such as dissolved oxygen (DO), pH, salinity, electrical conductivity (EC), fecal coliforms bacteria and the total coliforms bacteria met the standard for aquaculture. However, the nutrient, such as ammonium (NH4-N), nitri-nitrogen (NO2-N), nitrate-nitrogen (NO3-N) and soluble reactive phosphorus (PO4-P) were higher than the value of marine aquaculture standard. The results of the contamination of Salmonella spp. bacteria were not found in the mussel’s tissue, however Escherichia coli was found at very low level.

    Highlights: •EBSD of electroplated Zn on Fe or steel was performed. •Zn grows epitaxially on electropolished ferritic steel following Burger's orientation relation. •Surface deformation of steel leads to multiple electroplated zinc grains with random orientation. •Zn grows epitaxially even on industrial surfaces with little surface deformation. •Multiple zinc grains on one steel grain can show identical orientation relations. -- Abstract: The dependence of the crystal orientation of electrodeposited zinc of the grain orientation on ferritic steel substrate at high current density deposition (400 mA cm −2 ) during a pulse-plating process was investigated by means of EBSD (electron backscatter diffraction) measurements. EBSD-mappings of surface and cross-sections were performed on samples with different surface preparations. Furthermore an industrial sample was investigated to compare lab-coated samples with the industrial process. The epitaxial growth of zinc is mainly dependent on the condition of the steel grains. Deformation of steel grains leads to random orientation while zinc grows epitaxially on non-deformed steel grains even on industrial surfaces

    Full Text Available This study examines the relationship between current-account imbalances and economic growth during the 2008-2009 financial and economic crisis for 179 countries (covered by IMF data and within the EU-27 countries (covered by Eurostat data. The countries are divided into 4 groups by GDP per capita based on PPPs, namely, low income, lower middle-income, upper middle-income and high-income countries. Empirical analysis is applied, including descriptive statistics and regression estimates. Statistical data are used, including the average of the GDP growth rate in the years prior to the crisis (2003–2007, the average of the GDP growth rate for 2008 and 2009, current account as a percentage of GDP, and the level of average inflation. It is proved that, in general, the 2008-2009 crisis affected high- and upper middle-income countries more than poorer countries. Within the EU-27 countries, however, the crisis appears to have affected lower income countries more than higher income countries. A common tendency is observed for the two country samples: countries that experienced strong growth just prior to the crisis had an increased risk of suffering after the crisis. The boom prior to the crisis led to imbalances that rendered economies more vulnerable. Additionally, surpluses that existed prior to the crisis are an important risk factor for the two groups of countries.

    Full Text Available The paper looks at the issues related to the research on and assessment of the contagion effect. Based on several examinations of two selected EU countries, Poland paired with one of the EU member states; it presents the interaction between their economic development. A DCC-GARCH model constructed for the purpose of the study was used to generate a covariance matrix Ht, which enabled the calculation of correlation matrices Rt. The resulting variance vectors were used to present a linear correlation model on which a further analysis of the contagion effect was based. The aim of the study was to test a contagion effect among selected EU countries in the years 2000–2014. The transmission channel under study was the GDP of a selected country. The empirical studies confirmed the existence of the contagion effect between the economic development of the Polish and selected EU economies.

    Full Text Available Kantian philosophy that underpins our approach denies the possibility of any a priori knowledge (Kant, 2009. Only time and space, as frameworks of our experiences (and not as sizes are given a priori to humans. A priori knowledge is not possible according to the approach of the great philosopher, and the adoption of the appearance principle leads to the same conclusion. Our representations of the world appear as a result of our perceptions accumulated about the world as a result of our own experiences. And when we say personal experiences we mean both direct contacts with the outside world and the contacts mediated by others. The experience of reading is, from this point of view, an experience like any other, involving sensory perceptions (transmitted through sight and their representations. The only difference between this experience and one that involves direct contact with the outside world is that the last mentioned involves the need for knowledge resulting from previous experiences. It is obvious that this is not a priori knowledge unless we relate to our current situation. In this situation knowledge is not acquired "without any experience" but as a result of the experiences of others. Next we will try to see the connection between this knowledge and representations, gained as a result of the past experiences, and the concept of system of values.

    Full Text Available . The article presents an analysis of the way public debt operates in Romania, in the context of states economies trends, of complex and topical financial environments. In the context of a functional market economy, the issues faced by certain states involving high public debt levels or potential budgetary pressure risks converge towards the idea that public finances sustainability needs to be a major challenge at the level of public policies. Considering this situation, the adequate policies to tackle public finances sustainability need to have, as a launching base, the overall strategy of the European Union, focused on the three component parts, namely abatement of public debt, increasing productivity and employment and last but not least, reforming the pension and healthcare systems. To ensure reasonably sustainable public debt levels, EU member states need to attain medium term strategic budgetary objectives, that would ensure a downward trend of public debt, a condition which can be fulfilled by compliance with budget policies rules, which ground development in the macroeconomic framework.

    The basic way to improve the performance of a superconducting current limiter is to apply and evaluate a superconducting device that is appropriate to the superconducting current limiter. Among the many types of superconducting devices, the YBCO thin film wire has excellent current-limiting performance that is appropriate for actual system application. For the application of the YBCO thin film wire to superconducting current limiters, its current-limiting performance as a unit device must be accurately evaluated, and measures to improve its current-limiting performance must be sought. Accordingly, to evaluate the current-limiting performance of the YBCO thin film wire, this study was conducted to evaluate its resistance-increasing trend, V max , T r , I max , I qt , and current-limiting rate as a unit device, after which the electric coupling condition that consists of a core and windings was used to evaluate the current-limiting performance of the YBCO thin film wire.

    Full Text Available The aim of the article is to study principles, economic and institutional prerequisites for fiscal decentralization on post-conflict territories. It is determined that fiscal decentralization is one of the main ways to solve problems of post-conflict areas. There justified principles, economic and institutional prerequisites of fiscal decentralization on post-conflict territories with regard to the specificity of individual spheres of fiscal relations. Moreover, different spheres of fiscal relations require different approaches: the sphere of public revenues — providing economic efficiency with the formation of the tax structure contributing to the expansion of the tax base; the sphere of public spending — ensuring social justice and transparency in allocation of social cost at the local level; the sphere of subsidies — narrowing the scope of application of intergovernmental transfers with organizing the redistribution of financial resources under the principle of «center - post-conflict regions - post-conflict recipients»; the sphere of external assistance — ensuring proper coordination for cultivation of new co-operative institutions.

    We know little about the relationship between the macroeconomy and birth outcomes, in part due to the methodological challenge of distinguishing effects of economic conditions on fetal health from effects of economic conditions on selection into live birth. We examined associations between state-level unemployment rates in the first 2 trimesters of pregnancy and adverse birth outcomes, using natality data on singleton live births in the United States during 1990-2013. We used fixed-effect logistic regression models and accounted for selection by adjusting for state-level unemployment before conception and maternal characteristics associated with both selection and birth outcomes. We also tested whether associations between macroeconomic conditions and birth outcomes differed during and after (compared with before) the Great Recession (2007-2009). Each 1-percentage-point increase in the first-trimester unemployment rate was associated with a 5% increase in odds of preterm birth, while second-trimester unemployment was associated with a 3% decrease in preterm birth odds. During the Great Recession, however, first-trimester unemployment was associated with a 16% increase in odds of preterm birth. These findings increase our understanding of the effects of the Great Recession on health and add to growing literature suggesting that macro-level social and economic factors contribute to perinatal health. © The Author(s) 2017.

    Full Text Available In the quest for energy conservative building design, there is now a great opportunity for a flexible and sophisticated air conditioning system capable of addressing better thermal comfort, indoor air quality, and energy efficiency, that are strongly desired. The variable refrigerant volume air conditioning system provides considerable energy savings, cost effectiveness and reduced space requirements. Applications of intelligent control like fuzzy logic controller, especially adapted to variable air volume air conditioning systems, have drawn more interest in recent years than classical control systems. An experimental analysis was performed to investigate the inherent operational characteristics of the combined variable refrigerant volume and variable air volume air conditioning systems under fixed ventilation, demand controlled ventilation, and combined demand controlled ventilation and economizer cycle techniques for two seasonal conditions. The test results of the variable refrigerant volume and variable air volume air conditioning system for each techniques are presented. The test results infer that the system controlled by fuzzy logic methodology and operated under the CO2 based mechanical ventilation scheme, effectively yields 37% and 56% per day of average energy-saving in summer and winter conditions, respectively. Based on the experimental results, the fuzzy based combined system can be considered to be an alternative energy efficient air conditioning scheme, having significant energy-saving potential compared to the conventional constant air volume air conditioning system.

    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

    Full Text Available Uno de los temas indagados en el Segundo estudio nacional realizado por el Observatorio Costarricense de Mipymes durante el 2011 corresponde al financiamiento de las micros, pequeñas y medianas empresas costarricenses. Se consultaron las fuentes de financiamiento más utilizadas, la presentación de solicitudes de crédito durante los últimos cinco años, la utilización que en general hacen estas empresas de los diferentes medios de financiamiento y sus requerimientos actuales. De forma similar a lo que ocurre en otros países, los fondos propios constituyen la principal opción para estas empresas. Por ello, en este trabajo han sido analizadas las condiciones que propician la autofinanciación o el uso de otras opciones. Por medio del análisis estadístico de la información recopilada en la encuesta, se comprueba que algunas variables relativas a la gestión empresarial, tales como la fuente de financiamiento inicial, la experiencia del (de la empresario(a y la prioridad que dan al manejo de aspectos financieros, presentan una asociación significativa con las estrategias de financiamiento en las mipymes costarricenses. ABSTRACT Financing was one of the areas investigated in the Second National Survey of micro, small and medium sized Costa Rican companies during 2011. The most used financing sources, credit applications during the last five years, end use of this credit, and current credit requirements in various financing institutions were investigated. Similar to other countries, own funding was the main option for these companies. Thus, this work examines the conditions that facilitate the use of self financing or other options available. Through statistic analysis of the information collected, variables like initial funding source, previous experience of the entrepreneur and priority given to financial management were shown to present a definite relationship to financing strategies for Costa Rican SMEs.

    Conditions data (for example: alignment, calibration, data quality) are used extensively in the processing of real and simulated data in ATLAS. The volume and variety of the conditions data needed by different types of processing are quite diverse, so optimizing its access requires a careful understanding of conditions usage patterns. These patterns can be quantified by mining representative log files from each type of processing and gathering detailed information about conditions usage for that type of processing into a central repository.

    The objective of this study was to determine the prevalence and estimate total costs for chronic health conditions in the U.S. workforce for the Dow Chemical Company (Dow). Using the Stanford Presenteeism Scale, information was collected from workers at five locations on work impairment and absenteeism based on self-reported "primary" chronic health conditions. Survey data were merged with employee demographics, medical and pharmaceutical claims, smoking status, biometric health risk factors, payroll records, and job type. Almost 65% of respondents reported having one or more of the surveyed chronic conditions. The most common were allergies, arthritis/joint pain or stiffness, and back or neck disorders. The associated absenteeism by chronic condition ranged from 0.9 to 5.9 hours in a 4-week period, and on-the-job work impairment ranged from a 17.8% to 36.4% decrement in ability to function at work. The presence of a chronic condition was the most important determinant of the reported levels of work impairment and absence after adjusting for other factors (P < 0.000). The total cost of chronic conditions was estimated to be 10.7% of the total labor costs for Dow in the United States; 6.8% was attributable to work impairment alone. For all chronic conditions studied, the cost associated with performance based work loss or "presenteeism" greatly exceeded the combined costs of absenteeism and medical treatment combined.

    The increasing medical-technical progress as well as the dramatic demographic changes cause problems with regard to rapid enlargement of medical service offers, allocation of resources and a financing shortfall in the German public health system. The economization in the German Health System can also be perceived in ENT departments. After performing an internet search about the rapidly growing market for qualifications measures in health economics, we hence conducted an anonymous survey for ENT senior doctors and directors of the 34 German University Departments to evaluate their attitude towards, as well as their expectation of such an add-on qualification. Since the German government finalized the health care reform in the year 2000 such qualification measures rapidly developed: amongst others, 26 postgraduate, extra-occupational master programs have been inaugurated. The anonymous survey was answered by 105 ENT doctors (63 senior doctors, 27 vice professors and 15 directors). 63% out of these 105 colleagues considered such an add-on qualification to be mandatory. 41% of the colleagues were already "add-on qualified" in that field, only 10 of them by means of a study program. 71 of 105 colleagues (68%) considered the add-on qualification to be advantageous for their future personal career. With regard to the designated contents of the study program, "Staff Management" was even prioritized to "Hospital Financing" and "Cost Accounting". Aspects of management and a (health-) economical basic knowledge became an integral part of the daily routine for "first-line management doctors" also in (University) ENT-departments. © Georg Thieme Verlag KG Stuttgart · New York.

    This paper considers different cooling systems and investigates the most promising alternatives when solar energy is to be used to supply the cooling demand. All the systems are evaluated during a summer cooling season by the energetic and economic point of view by dynamic simulation for two different climates. For Milan (Cfb climate) the highest OSE (overall system efficiency) is reached by LiBr (lithium-bromide) double effect absorption chiller driven by parabolic through collector (0.53). In terms of the collecting surface area, the best systems for Milan feature 0.08 m 2  MJ −1 per day both for electric system (mono-crystalline photovoltaic coupled to water cooled chiller) and thermal system (PTC (parabolic trough collectors) coupled to double effect water-LiBr absorption chiller). Southern latitudes like Trapani (Csa climate) allow a quite better performance for thermal solar cooling solutions. The NPV (net present worths) of electric solar cooling solutions are favorable with respect to the traditional solution and the DPV (discounted payback periods) are all lower than the period of economic analysis above all for water cooled chillers. Finally a sensitivity analysis of the specific investment cost (€ MJ −1 per day) is carried out regarding the investment cost of collectors, the solar ratio and the interest rate. - Highlights: • Solar cooling is obtained with solar thermal or PV (photovoltaic) with easy available equipment. • In the past PV driven systems for solar cooling were not considered as too expensive. • An energy/economic comparison is carried out for the various solar cooling systems. • Sensitivity analyses are carried out varying different parameters

    The aim of this study was to estimate the economic burden of celiac disease (CD) in Iran. The assessment of burden of CD has become an important primary or secondary outcome measure in clinical and epidemiologic studies. Information regarding medical costs and gluten free diet (GFD) costs were gathered using questionnaire and checklists offered to the selected patients with CD. The data included the direct medical cost (including Doctor Visit, hospitalization, clinical test examinations, endoscopies, etc.), GFD cost and loss productivity cost (as the indirect cost) for CD patient were estimated. The factors used for cost estimation included frequency of health resource utilization and gluten free diet basket. Purchasing Power Parity Dollar (PPP$) was used in order to make inter-country comparisons. Total of 213 celiac patients entered to this study. The mean (standard deviation) of total cost per patient per year was 3377 (1853) PPP$. This total cost including direct medical cost, GFD costs and loss productivity cost per patients per year. Also the mean and standard deviation of medical cost and GFD cost were 195 (128) PPP$ and 932 (734) PPP$ respectively. The total costs of CD were significantly higher for male. Also GFD cost and total cost were higher for unmarried patients. In conclusion, our estimation of CD economic burden is indicating that CD patients face substantial expense that might not be affordable for a good number of these patients. The estimated economic burden may put these patients at high risk for dietary neglect resulting in increasing the risk of long term complications.

    Highlights: • We compare two remediation scenarios; one with resource recovery and one without. • Economic analysis includes relevant direct costs and revenues for the landfill owner. • High degrees of metal and/or combustible contents are important economic factors. • Landfill tax and the access to a CHP can have a large impact on the result. • Combining landfill mining and remediation may decrease the project cost. - Abstract: This article analyzes the economic potential of integrating material separation and resource recovery into a landfill remediation project, and discusses the result and the largest impact factors. The analysis is done using a direct costs/revenues approach and the stochastic uncertainties are handled using Monte Carlo simulation. Two remediation scenarios are applied to a hypothetical landfill. One scenario includes only remediation, while the second scenario adds resource recovery to the remediation project. Moreover, the second scenario is divided into two cases, case A and B. In case A, the landfill tax needs to be paid for re-deposited material and the landfill holder does not own a combined heat and power plant (CHP), which leads to disposal costs in the form of gate fees. In case B, the landfill tax is waived on the re-deposited material and the landfill holder owns its own CHP. Results show that the remediation project in the first scenario costs about €23/ton. Adding resource recovery as in case A worsens the result to −€36/ton, while for case B the result improves to −€14/ton. This shows the importance of landfill tax and the access to a CHP. Other important factors for the result are the material composition in the landfill, the efficiency of the separation technology used, and the price of the saleable material

    Full Text Available The article is devoted to the analysis of social risks and deviations related to family group in Ural, manifestations of these risks for a family way of life, socio-economic development of the region. The author emphasizes that today the dialectics of creation and destructions, risks and reliability, optimism and pessimism is illustrated in the various parts of the institute of family in Russia as a whole and, in particular, in the Ural region. In our modern age, there is no risk-free behavior. «Risk — safety» dichotomy means that there is no absolute reliability or safety. Whereas «risk — danger» dichotomy means that it is impossible to avoid risk, making any decisions. The author shows the identity of socio-economic health of the adult population of various regions of the Russian Federation throughout almost the whole quarter of a century on the basis of a number of research assignments conducted by sociologists of Institute of Economics of the UB RAS, in a monitoring mode. Division of the population on rather identical (on particular weight in the total number of the population groups of the Russian society referred to the category of «rich», «medium people» and «poor people» is observed. At the same time, according to the author, the social inequality in principle has both positive, and negative consequences for functioning and society development. The author made an attempt of the problem analysis of «family — children», «fathers — children» from a perspective social risks. The special relevance of these processes in relation to family policy in Russia seeking to pass from depopulation tendencies to a favorable treatment of nation-expanded reproduction is emphasized. Altogether, the level of family wellbeing, first of all, is defined by the quality of the relations in the system of «parents — children». The intra-familial conflicts conduct to family trouble and so for children. In article, the author’s position

    Anodic TiO2 nanotubes have been studied extensively for many years. However, the growth kinetics still remains unclear. The systematic study of the current transient under constant anodizing voltage has not been mentioned in the original literature. Here, a derivation and its corresponding theoretical formula are proposed to overcome this challenge. In this paper, the theoretical expressions for the time dependent ionic current and electronic current are derived to explore the anodizing process of Ti. The anodizing current-time curves under different anodizing voltages and different temperatures are experimentally investigated in the anodization of Ti. Furthermore, the quantitative relationship between the thickness of the barrier layer and anodizing time, and the relationships between the ionic/electronic current and temperatures are proposed in this paper. All of the current-transient plots can be fitted consistently by the proposed theoretical expressions. Additionally, it is the first time that the coefficient A of the exponential relationship (ionic current jion = A exp(BE)) has been determined under various temperatures and voltages. And the results indicate that as temperature and voltage increase, ionic current and electronic current both increase. The temperature has a larger effect on electronic current than ionic current. These results can promote the research of kinetics from a qualitative to quantitative level.

    2015-01-01

    To meet growing demand for wood, particularly softwoods, the authors study a number of new silvicultural pathways for planting 3 species: Douglas fir, spruce and maritime pine. The goal of these pathways is to achieve specialised production of either industrial and workable timber, or a mixture of industrial and workable timber with medium-diameter workable timber. Pathways of this type have already been standardised for hardwoods, generally on fertile farmland. In a less fertile forest context, softwoods have a significant potential for woody production but specialized pathways and their profitability have yet to be studied. This article describes the innovative work being done to construct and simulate profitable production, new potential pathways, where plantation density, rotation time, the level of fertility are made to vary using the data from the FCBA test network in conjunction with the FCBA growth models (Oasis for spruce and Douglas fir, Sylveco for maritime pine). Economic data is derived from auction sales statistics and the ONF management and forestry work costs for the period 2012-2015. The Economics module developed by FCBA and ONF on the Capsis platform in the framework of the ICI project (Futurol) was used for the economic simulations. The analyses show that compared to conventional pathways, these pathways generally increase productivity but are nonetheless less profitable than current economic assumptions, although results vary according to species, fertility and the particular pathway. The sensitivity study shows that variations in the price of wood could alter the performance ratings as between conventional and specialised pathways. (authors)

    2014-12-01

    Full Text Available The paper examines the ambiguous contextual manifestations that accompany the process of formation of Russian entrepreneurial community. The work presents the research results of the specifics of these manifestations derived based on the analysis of various materials from Russian official, scientific and sociopolitical as well as international sources. "Attitude towards entrepreneurship" is regarded as the most important sociocultural component of the development of the entrepreneurship as a social practice. The identified economic and political as well as sociocultural trends that accompany the formation of the modern Russian entrepreneurship reflect the incompleteness stage of the market reforms in Russia. The creation of the modern ethical basis of the development of the entrepreneurship and its interaction with the society is assumed as one of the ways to accelerate these reforms. The outcome of the present interdisciplinary work - which is in its own way “a view from the outside” - in the author’s opinion, indicates the equivalence of sociocultural and economic and political range of problems for the modern stage of development of the entrepreneurship in Russia.

    The main producer of electric energy in Lithuania is Ignalina NPP with its two RBMK-1500 type reactors. It covers up to 86% of total annual electricity production. The compulsory premature closure of Ignalina NPP due to the decision of EU authorities will decrease maximum power generating capacity to 3273 MW in the year 2010 (slump of 42% in respect to 5698 MW of the year 2000) and it will cause a complex of serious technical, economical, ecological, and social consequences. The most important ones for energy sector are the negative power balance and the shortage of power generating capacity which can emerge straight after closure of the second unit of Ignalina NPP. An attempt has been taken to prove, that the most realistic way for replacement of lost power generating capacities is the construction of new nuclear or combined cycle gas turbine power plants. The results of the comparative analysis of their effectiveness and competitiveness are presented in the paper. Estimating the basic prevailing technical and economical factors and three possible scenarios of economy growth, the changes of power balance and levelised cost of produced electricity are compared. It is demonstrated that a new modern nuclear power plant would be competitive and it would be even a more favourable option in respect to a combined cycle gas turbine power plant due to the relatively lower energy production cost, especially when estimating the possible future growth of price for fossil fuel.

    Full Text Available This paper shows the economic situation of economically weak farms in 8 countries of Central and Eastern Europe(CEE in 2010. The data were obtained from the survey on EU farms carried out under the FADN system. The studyincluded countries in which economically weak farms were the dominant farm type (i.e. Bulgaria, Estonia, Hungary,Latvia, Lithuania, Poland, Romania and Slovakia. The aim of the study was to assess the economic performance ofthose farms and indicate advantages of the competing farm types. The analysis was performed in terms of totalfactor productivity, income levels, assets and debt level. The influence of CAP instruments on managementefficiency was also demonstrated. The study found a high diversity in terms of production potential as well asfinancial condition of farms in particular countries, whereas one point of correspondence between farms is theprevalence of fixed assets, i.e. an excessive assets-to-area ratio, and the dominance of own capital in financingthose assets. Romanian, Polish and Bulgarian farms are characterised by the highest efficiency of use of currentoutlays and, in turn, a lower cost of the production unit, which accounted for 66%, 86% and 87% of the outputvalue respectively. In Latvia, Estonia and Slovenia, the costs exceeded the output value by 6%, 7% and 23%respectively and, as a result, the income of those farms was generated exclusively due to subsidies.

    2015-01-01

    The French law of 20.01.2014 recently instituted an arduous working conditions allowance. This innovated legislation is designed to improve the status of workers subject to arduous working conditions either by allowing lighter work schedules or job reclassification or early retirement. The impact of arduous working conditions on health has been clearly established, but no consensual solution has yet been proposed. Life expectancy without disability can differ by as much as 9 years between higher executives and manual workers, but the proposed solutions comprise a multitude of perverse effects. Workers may benefit from maintaining their arduous working conditions in order to preserve their right to early retirement. Companies do not necessarily have the desire or the resources to invest in prevention, which is the only consensually accepted effective measure, if they are also required to finance both training and retirement. In particular, management of the arduous working conditions allowance is very complex and entirely financed by companies. Consequently, company productivity can be impacted, leading to transfers of company headquarters, outsourcing to interim workers, replacement of jobs by automation. Unemployment could be the big winner of this conflict. Politically, arduous working conditions allowance appears to be very difficult to put into practice and can be considered to be more a promise by the government to the left and to the trade unions.

    The big data transformation currently revolutionizing science and industry forges novel possibilities in multi-modal analysis scarcely imaginable only a decade ago. One of the important economic and industrial problems that stand to benefit from the recent expansion of data availability and computational prowess is the prediction of electricity demand and renewable energy generation. Both are correlates of human activity: spatiotemporal energy consumption patterns in society are a factor of both demand (weather dependent) and supply, which determine cost - a relation expected to strengthen along with increasing renewable energy dependence. One of the main drivers of European weather patterns is the activity of the Atlantic Ocean and in particular its dominant Northern Hemisphere current: the Gulf Stream. We choose this particular current as a test case in part due to larger amount of relevant data and scientific literature available for refinement of analysis techniques. This data richness is due not only to its economic importance but also to its size being clearly visible in radar and infrared satellite imagery, which makes it easier to detect using Computer Vision (CV). The power of CV techniques makes basic analysis thus developed scalable to other smaller and less known, but still influential, currents, which are not just curves on a map, but complex, evolving, moving branching trees in 3D projected onto a 2D image. We investigate means of extracting, from several image modalities (including recently available Copernicus radar and earlier Infrared satellites), a parameterized representation of the state of the Gulf Stream and its environment that is useful as feature space representation in a machine learning context, in this case with the EC's H2020-sponsored 'See.4C' project, in the context of which data scientists may find novel predictors of spatiotemporal energy flow. Although automated extractors of Gulf Stream position exist, they differ in methodology

    Full Text Available At the ideological level, the current crisis, as the others in history, has triggered an intellectual debate among several applicable ideas: ultra-liberal theory of the "invisible hand" of Adam Smith, Keynes's theory of state interventionism and even neo-Marxist theories. Globalization, with all its core components, generates a chain reaction when the phenomenon occurs, either positive or negative. The origin of the current financial crisis should be sought in the effects of massive cross-border capital flows and the use of more complex derivatives. Reaching the saturation of the three engines of economic growth worldwide in the period after the collapse of the socialist bloc is another important cause of all the failures that currently exist worldwide. Acquisition of toxic assets from bank balance sheets, their recapitalization and takeover by the state, but also the reinforcement of the prudential supervision of capitalization, liquidity and risk management system, improved transparency and speed the process of evaluating or reinforcing authorities' response to risk, can be considered short or long term anti-crisis measures, as appropriate.

    2011-01-01

    Full Text Available This paper analyzes the importance of trust and management-to-employee communication among top Slovenian employers from the Golden Thread Survey. The paper analyzes the changes and impact of the deteriorating external economic situation on (a company-employee relational trust, and on the (b perceived importance of “trust and long-term relationships with the company in the eyes of the customer” by respondent managers. Furthermore, our analysis also looks at the impact of management-to-employee communication on both trust perspectives. The results show a stable level of company-employee relational trust in the face of the current economic crisis, despite a high level of perceived organizational process changes and a sharp decline in financial performance. On the other hand, the perceived importance of “trust and long-term relationships with the company in the eyes of the customer” has increased substantially as the crisis has deepened, supporting our claim that relationships and the external relationship orientation gain importance in the time of crisis. There is also a strong link between the degree of open and frequent management-to-employee communication, and both perspectives of measured trust among top Slovenian employers.

    2018-02-01

    The paper presents a simplified model that quantifies economic and technical consequences of changing conditions in wastewater systems on utility level. It has been developed based on data from stakeholders and ministries, collected by a survey that determined resulting effects and adapted measures. The model comprises all substantial cost relevant assets and activities of a typical German wastewater utility. It consists of three modules: i) Sewer for describing the state development of sewer systems, ii) WWTP for process parameter consideration of waste water treatment plants (WWTP) and iii) Cost Accounting for calculation of expenses in the cost categories and resulting charges. Validity and accuracy of this model was verified by using historical data from an exemplary wastewater utility. Calculated process as well as economic parameters shows a high accuracy compared to measured parameters and given expenses. Thus, the model is proposed to support strategic, process oriented decision making on utility level. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The recent economic recession represents an opportunity to test whether decreases in economic resources may have deleterious consequences on childhood overweight/obesity risk. We investigated the association between indicators of changing macroeconomic conditions from 2008 to 2012 and overweight/obesity risk among school-aged children in California (n=1 741 712) using longitudinal anthropometric measurements. Multivariate regression, with individual and county fixed effects, was used to examine the effects of annual county-level unemployment and foreclosure rates on risk of child overweight/obesity, overall and among subgroups (race/ethnicity, sex, county-level median household income and county-level urban/rural status). From 2008 to 2012, ∼38% of children were overweight/obese and unemployment and foreclosure rates averaged 11% and 6.9%, respectively. A 1-percentage point (pp) increase in unemployment was associated with a 1.4 pp (95% CI 1.3 to 1.5) increase in overweight/obesity risk. Therefore, a child of average weight could expect a 14% increase in their body mass index z-score in association with a 1 pp increase in unemployment during the study period. We found some differences in the magnitude of the effects for unemployment among demographic subgroups, with the largest effects observed for unemployment among American Indians and Pacific Islanders. Comparing children to themselves over time, we provide evidence that increases in county-level unemployment are associated with increased overweight/obesity risk. Given that overweight among children with lower economic resources remains a challenge for public health, these findings highlight the importance of policy-level approaches, which aim to mitigate the impact of decreased resources as economic conditions change.

He talked about the introduction of the Stability and Growth in a 'European quarter' which will be monitored in structural and fiscal policies of the Member States. He also held a first exchange of views about the possible introduction of a levy on banks and a tax on financial transactions. Thus, the European Union has moved to create the world's first supranational system of control over the financial markets, particularly in order to reduce the risk of global financial crisis. The system will act in early 2011. For the first time in history, European financial control agencies will have more seats than national governments. In addition, the European Central Bank will see a branch that will track the emergence of crisis risk.The financial crisis has diminished the EU's growth potential, and made it clear just how interdependent its members' economies are, particularly inside the eurozone. The most important priority now is to restore growth and create effective mechanisms for regulating financial markets - in Europe and internationally. In strengthening its system of economic governance, Europe must learn from previous shortcomings which have put the financial stability of the whole eurozone at risk:- poor observance of the EU's sound rules and procedures for economic policy coordination- insufficient reduction in public debt during the good times – with peer pressure proving an adequate incentive- failure to deal effectively with the build-up of macroeconomic imbalances - despite the Commission's warnings – resulting in high current account deficits, large external indebtedness and high public debt levels in a number of countries (above the official 60% limit for eurozone countries.

    An increased uptake of alternative low or non-CO2 emitting energy sources is one of the key priorities for policy makers to mitigate the effects of environmental change. Relatively little work has been undertaken on the mitigation potential of Ground Coupled Heat Pumps (GCHPs) despite the fact that a GCHP could significantly reduce CO2 emissions from heating systems. It is predicted that under climate change the most probable scenario is for UK temperatures to increase and for winter rainfall to become more abundant; the latter is likely to cause a general rise in groundwater levels. Summer rainfall may reduce considerably, while vegetation type and density may change. Furthermore, recent studies underline the likelihood of an increase in the number of heat waves. Under such a scenario, GCHPs will increasingly be used for cooling as well as heating. These factors will affect long-term performance of horizontal GCHP systems and hence their economic viability and mitigation potential during their life span ( 50 years). The seasonal temperature differences encountered in soil are harnessed by GCHPs to provide heating in the winter and cooling in the summer. The performance of a GCHP system will depend on technical factors (heat exchanger (HE) type, length, depth, and spacing of pipes), but also it will be determined to a large extent by interactions between the below-ground parts of the system and the environment (atmospheric conditions, vegetation and soil characteristics). Depending on the balance between extraction and rejection of heat from and to the ground, the soil temperature in the neighbourhood of the HE may fall or rise. The GROMIT project (GROund coupled heat pumps MITigation potential), funded by the Natural Environment Research Council (UK), is a multi-disciplinary research project, in collaboration with EarthEnergy Ltd., which aims to quantify the CO2 mitigation potential of horizontal GCHPs.

    Full Text Available Odisha (previously known as Orissa, being socio-economically backward but culturally sound, is one of the important states in Eastern India. Out of 30 districts 9 are considered as tribal districts (according to Location Quotient value and of the total population (41,947,358 in 2011 a significant share (22.1% goes to tribal people (8,145,081in 2011. This tribal group of Odisha has special significance because they are one of the most backward and geographically isolated communities. That’s why their life style and economy is confined to the direct utilization of natural resources, pre-agricultural level of technology and specific indigenous type of work. But now with the emergence of industry and market economy, the age-old relationship between tribes and nature has disturbed. Keeping this in backdrop, the present study tried to explore the changing scenario of socio-economic condition in the tribal areas of Odisha. In this regard, various socio-economic indicators have been analyzed and compared for representing district-level patterns of quality of life and finding out the variation among the Primitive tribal households in the study area. In addition, Mayurbhanj has also been taken as a case study to represent the socio-economic condition and quality of life at the block level. It may be pointed out in this context that out of 30 districts in Odisha, according to Location Quotient value Mayurbhanj is the highest tribal concentrated district. The overall objective of this study is to obtain a better understanding of disparities and variations in socio-economic status in Odisha as well as in Mayurbhanj and also find out some remedial measures to overcome the problems to bring the Primitive tribal community in the main stream of the society. Maps have been prepared on the above-mentioned indicators based on secondary data using Arc-GIS 9.3. From the analysis of the health-related indicators it is clear from the analysis that the quality of life

    Economists have traditionally been very cautious when studying the interaction between employment and health because of the two-way causal relationship between these two variables: health status influences the probability of being employed and, at the same time, working affects the health status. Because these two variables are determined simultaneously, researchers control endogeneity skews (e.g., reverse causality, omitted variables) when conducting empirical analysis. With these caveats in mind, the literature finds that a favourable work environment and high job security lead to better health conditions. Being employed with appropriate working conditions plays a protective role on physical health and psychiatric disorders. By contrast, non-employment and retirement are generally worse for mental health than employment, and overemployment has a negative effect on health. These findings stress the importance of employment and of adequate working conditions for the health of workers. In this context, it is a concern that a significant proportion of European workers (29 %) would like to work fewer hours because unwanted long hours are likely to signal a poor level of job satisfaction and inadequate working conditions, with detrimental effects on health. Thus, in Europe, labour-market policy has increasingly paid attention to job sustainability and job satisfaction. The literature clearly invites employers to take better account of the worker preferences when setting the number of hours worked. Overall, a specific "flexicurity" (combination of high employment protection, job satisfaction and active labour-market policies) is likely to have a positive effect on health.

    The theory of compensating differentials asserts that night shift workers should receive compensating wage differentials due to undesirable work conditions. In weak local economies, workers may have difficulty finding jobs; thus, these workers might be more likely to accept night shift work and be less concerned with the size of the compensating differential for night shifts. Using CPS data from 2001, this paper employs maximum likelihood estimation of an endogenous switching regression model...

  20. Effect of accelerating field third harmonic on microtron steady-state conditions and limiting current

    Setting the acceleration regime in a microtron with the resonator in which the third accelerating field harmonic is excited by accelerated clusters is considered. It is shown that excitation of the accelerating field third harmonic in the microtron resonator (E 011 mode) causes a 1.5 time increase of the range of field intensity values under which resonance particle acceleration is possible. Under moderate energies and accelerated currents (10-15 MeV, 50-80 mA) this leads to a reduction of requirements to the stability of power coming to the resonator and cathode temperature. Under accelerated currents of > 100 mA the third harmonic complicates the microtron transition to acceleration regime. The microtron transfers to stable autooscillation regime, but the current achieved in a single short pulse is increased. By varying the value of the resonator quality factor on the third harmonic one can change the current pulse duration and autooscillation period

    Full Text Available The paper considers a problem of structural optimization of financial streams in the economic activities of the enterprises. The authors describe a general process of enterprise capital structure optimization while breaking it in stages and consider the most interesting financial stream theories. The paper presents for the first time «Combined optimization model». In order to develop the model the most commonly applied methods have been used, namely: an optimization  method on the basis of an average capital price, an optimization method on the basis of financial leverage effect and an optimization method on the basis of the average managing subject price. Alternative calculations of optimum structure of financial stream sources on the basis of the proposed «combined model» have been presented in corresponding tables. The authors also use for the first time such concepts as «a break-even point» and «a safety zone» in respect of enterprise financial streams while using a graphic method.

    Full Text Available In the article trust analysis to the major regional authorities on the level of the Northern sub-Arctic region of Yamalo-Nenets Autonomous area has been carried out. It is supposed methodologically, that trust circles act as the key element and long-term economic development precondition because they reduce transactions costs, allow you to make in a broader planning horizon, building relationships in the «power – business – society» triad. Empirical data shows that the regional society trust in the Yamalo- enets Autonomous area is at risk. The political parties, trade unions, the legislature of the region are least trusted by the Northern region’ residents, as, indeed, by all residents of Russia. The court as a mean of protecting basic rights and freedoms and the Governor are considered to be the trust leaders among regional government institutions. The very high level of protest expectations is being supported by fairly sizeable (one third of the region residents protest potential level. Taking into account the relative trust reduction to the Governor of the region by of Yamalo-Nenets Autonomous area’ residents, this mood cannot but arouse concerns. This situation distinguishes the Northern region’ residents from the other two sub-regions of the Tyumen region ones, where more than half of the population trusts the Governor, and there is positive dynamics of trust.

  3. Comparative economic assessment of ethanol production under mesophilic and thermophilic conditions

    1991-01-01

    Key technical factors affecting the economics of bioethanol production are critically analyzed with special reference to the relative merits of thermophilic and mesophilic fermentation. A number of novel process schemes to take advantage of thermophilic operation are discussed. Analysis of the capital and operating costs for a range of flowsheets then provides a basis for critical study. Estimates for thermophilic production are compared with those for a sugar cane based mesophilic process (using S. cerevisiae). For the thermophilic fermentation, the basic kinetic and yield constants are based on projected values for a strain of B. stearothermophilus. Compared to mesophilic operation, thermophilic operation results in reduced capital, operating and feed costs. The feed cost still accounts for a large proportion (75%) of the total production cost. However, on a feed-cost-free basis, a reduction in production cost of up to 32% could be realized by changing to thermophilic operation from existing yeast-based processes, after minor process modifications. 20 refs., 10 figs., 8 tabs

    Ocean surface boundary layer dynamics off the southern coast of France in the NW Mediterranean is investigated by using velocity observations by high-frequency (HF) radars, surface drifting buoys and a downward-looking drifting acoustic Doppler current profiler (ADCP). The analysis confirms that velocities measured by HF radars correspond to those observed by an ADCP at the effective depth z f = k -1, where k is wavenumber of the radio wave emitted by the radar. The radials provided by the radars were in a very good agreement with in situ measurements, with the relative errors of 1 and 9 % and root mean square (RMS) differences of 0.02 and 0.04 m/s for monostatic and bistatic radar, respectively. The total radar-based velocities appeared to be slightly underestimated in magnitude and somewhat biased in direction. At the end of the survey period, the difference in the surface current direction, based on HF radar and ADCP data, attained 10°. It was demonstrated that the surface boundary layer dynamics cannot be reconstructed successfully without taking into the account velocity variation with depth. A significant misalignment of ˜30° caused by the sea breeze was documented between the HF radar (HFR-derived) surface current and the background current. It was also found that the ocean response to a moderate wind forcing was confined to the 4-m-thick upper layer. The respective Ekman current attained the maximum value of 0.15 m/s, and the current rotation was found to be lagging the wind by approximately 40 min, with the current vector direction being 15-20° to the left of the wind. The range of velocity variability due to wind forcing was found comparable with the magnitude of the background current variability.

    The capacity of turbidity currents to carry sand and coarser sediment from shallow to deep regions in the submarine environment has attracted the attention of researchers from different disciplines. Yet not only are field measurements of oceanic turbidity currents a rare achievement, but also the data that have been collected consist mostly of velocity records with very limited or no suspended sediment concentration or grain size distribution data. This work focuses on two turbidity currents measured in Monterey Canyon in 2002 with emphasis on suspended sediment from unique samples collected within the body of these currents. It is shown that concentration and grain size of the suspended material, primarily controlled by the source of the gravity flows and their interaction with bed material, play a significant role in shaping the characteristics of the turbidity currents as they travel down the canyon. Before the flows reach their normal or quasi-steady state, which is defined by bed slope, bed roughness, and suspended grain size, they might pass through a preliminary adjustment stage where they are subject to capacity-driven deposition, and release heavy material in excess. Flows composed of fine (silt/clay) sediments tend to be thicker than those with sands. The measured velocity and concentration data confirm that flow patterns differ between the front and body of turbidity currents and that, even after reaching normal state, the flow regime can be radically disrupted by abrupt changes in canyon morphology.

    Often, legal regulations governing the electricity and gas industries are thought prematurely to apply to district heating as well. The author shows that the technical and economic boundary conditions of district heating are quite different in many respects. He starts by explaining the concept of district heating and analyzing its economic boundary conditions. The next instalment will follow in the next issue of EuroHeat and Power and will focus on the heat market and its legal boundary conditions.

    Conditions data (for example: alignment, calibration, data quality) are used extensively in the processing of real and simulated data in ATLAS. The volume and variety of the conditions data needed by different types of processing are quite diverse, so optimizing its access requires a careful understanding of conditions usage patterns. These patterns can be quantified by mining representative log files from each type of processing and gathering detailed information about conditions usage for that type of processing into a central repository. In this presentation, we describe the systems developed to collect this conditions usage metadata per job type and describe a few specific (but very different) ways in which it has been used. For example, it can be used to cull specific conditions data into a much more compact package to be used by jobs doing similar types of processing: these customized collections can then be shipped with jobs to be executed on isolated worker nodes (such as HPC farms) that have no netwo...

    With popular application of graphene and graphene oxide (GO), they have been discharged into water. Graphene and GO harm organisms. However, an efficient and economical method for removing graphene and GO in wastewater has seldom been reported. Graphene can be oxidized by hydrogen peroxide to give GO; therefore, degradation of graphene oxide is an important step in the procedure of removal of graphene from water. In this paper, GO degradation via photo-Fenton reaction under different conditions was carried out. Experimental results suggested that GO in wastewater can be efficiently and economically degraded into carbon dioxide and H 2 O when pH value is 3, concentration of H 2 O 2 and FeCl 3 are 35 mM and 5 ppm, respectively. Degradation mechanism of GO was suggested based on UV-vis absorption spectra, scanning electron microscopy, X-ray diffraction and liquid chromatography-mass spectra data of degradation intermediates. This paper suggests an efficient and economical degradation way of GO in wastewater.

    Full Text Available The article is concerned with the methodology of economic substantiation of real investments in case of considerable lack of information on possible fluctuations of initial parameters and the resulting risk. The analysis of sensitivity as the main instrument for accounting the risk in the indicated problem situation is the focus of the presented research. In the publication, on the basis of the apparatus of interval mathematics, a set of models for comparative estimation of economic attractiveness (efficiency of alternative investment projects in conditions of uncertainty and risk is formulated, using the sensitivity analysis. The developed instrumentarium assumes both mono- and poly-interval version of the sensitivity analysis. As the risk component in the constructed models is used: in some – values of the specially developed sensitivity coefficient, in others – the worst values, which are based on the interval estimations of the partial criteria of efficiency. The sensitivity coefficient, according to the approach proposed in the publication, is the ratio of the target semi-range of variation to the increase (economy of efficiency, which is provided when the basic level of the analyzed partial criterion of economic attractiveness in comparison with some of its threshold (limit value is being reached.

    Full Text Available This study used a spatially-explicit model to identify the amount and spatial distribution of economically feasible sites for establishing dedicated energy crops under various market and policy scenarios. A sensitivity analysis was performed for a biomass market with different discount rates and biomass prices as well as policy scenarios including propriety tax exemption, carbon offset payments, and the inclusion of farmland for biomass production. The model was applied to a four-county study area in Kentucky representing conditions commonly found in the Ohio River Valley. Results showed that both biomass price and discount rate have a can strongly influence the amount of economically efficient sites. Rising the biomass price by 5 $·t−1 and lowering discount rate by 1% from the baseline scenario (40 $·t−1 and 5% resulted in an over fourteen fold increment. Property tax exemption resulted in a fourfold increase, a carbon payment on only 1 $·t−1 caused a twelve fold increase and extending the landbase from marginal land to farmland only slightly increase the economically efficient sites. These results provide an objective evaluation of market and policy scenarios in terms of their potential to increase land availability for establishing dedicated energy crops and to promote the bioenergy industry.

    An analysis of practicable conditioning technologies for uranium mill tailings and their estimated costs has been conducted for two conditioning alternatives, thermal stabilization and leaching (sulfuric acid). Among the four high priority remedial action sites, Canonsburg, Pennsylvania, and Shiprock, New Mexico appear to be very good candidates for thermal stabilization. At Shiprock, thermal stabilization appears to be less expensive ($16.01/ton) than moving the pile more than five miles and covering with 15 feet of earth. At Canonsburg costs of other alternatives are not presently available. Given the radiological monitoring and protection expenses attendant upon moving these tailings in a highly populated area, it is likely that thermal stabilization, on site, at $41.25/ton would be an attractive remedial action approach. Cost data on the Salt Lake City, Utah site are presented for comparison purposes. Thermal stabilization is not favorable at this site because of high fuel and labor costs, as well as other factors. A conceptual design for a thermal stabilization operation is described. Sufficient information to assess the leaching alternative is available only for the Durango, Colorado site. Because of the large amount of vanadium and uranium in the pile, the income from the sale of these strategic minerals could pay for as much as 58% of the expense of removing, transporting, and covering the pile

    Full Text Available The aim of the article is to assess – on the basis of a comparison of Czech and Slovak legislation relating to the conditions of the minimum wage indexation – whether it would be appropriate to use certain aspects of Slovak legislation in the Czech legislation and vice versa. When elaborating the article, some logical methods were used. In order to collect data, important employers were addressed in the South-Moravian Region. A carrying method used during the work was a comparison. Analyses were processed using the data of the Czech Statistical Office, the European Statistical Office and the Ministry of Labour and Social Affairs of the Czech Republic. To evaluate the research, the percentage representation of positive and negative responses and Pearson’s Chi-square test were used. The paper presents the results of research whose aim was to get the views of entrepreneurs regarding the minimum wage level and conditions of its indexation. Employers supported the idea of maintaining the institution of the minimum wage. A predominant portion of companies would welcome it if the minimum wage were derived on the basis of an average wage, and the vast majority of companies would welcome the annual indexation of the minimum wage by inflation.

  17. Transition conditions for solid armatures in railguns with muzzle current feed

    Velocity skin effect is a principle reason that solid armatures in railguns transition from smooth metal-on-metal contact with the rails to arcing contact. Transition occurs when armature velocity reaches some critical value which depends weakly on current and strongly on the latent heat of evaporation and electrical conductivity of the armature material. Conductivity of the rail material is also a factor. The analysis shows that when current is fed to the armature from the muzzle of a railgun armature to rail current distribution is more uniform over the contact face than is the case with normal breech feed. The authors show that muzzle feed allows transition velocity to be increased three-fold

    Highlights: • Influence of reaction parameters on FAME yields has been investigated. • The highest yield (93%) was achieved after 15 min at 350 °C and 12 MPa. • Models which predict with high certainty yields at different reaction conditions. • Economic and environmental performance of supercritical transesterification. • The lowest costs and impacts are always achieved at the highest yields. - Abstract: This study aims to investigate the influence of various reaction parameters (temperatures, working pressures and reaction time) on biodiesel yields and environmental and economic performance of rapeseed oil transesterification in supercritical methanol. Experiments were carried out in a laboratory-scale batch reactor. Results were statistically analysed and multiple regression models which describe and predict biodiesel yields with high certainty at different reaction conditions were provided. The highest biodiesel yield (93 wt%) was achieved at 350 °C and 12 MPa after 15 min of reaction. The lowest direct costs and life cycle environmental impacts (in terms of GHG emissions and fossil energy demand) are achieved at the highest yield due to the lowest oil consumption per unit of biodiesel produced. The results of sensitivity analysis showed that even at significantly lower oil feedstock prices this observation stands firm

    Till recently analysis of vibration signals was the only means available to predict the state of health of plant equipment. Motor current and leakage magnetic flux signature analysis is acquiring importance as a technique for detection of incipient damages in the electrical machines and as a supplementary technique for diagnostics of driven equipment such as centrifugal and reciprocating pumps. The state of health of the driven equipment is assessed by analysing time signal, frequency spectrum and trend analysis. For example, the pump vane frequency, piston stroke frequency, gear frequency and bearing frequencies are indicated in the current and flux spectra. By maintaining a periodic record of the amplitudes of various frequency lines in the frequency spectra, it is possible to understand the trend of deterioration of parts and components of the pump. All problems arising out of inappropriate mechanical alignment of vertical pumps are easily identified by a combined analysis of current, flux and vibration signals. It is found that current signature analysis technique is a sufficient method in itself for the analysis of state of health of reciprocating pumps and compressors. (author). 10 refs., 4 figs

    In recent years, the conditions of development and functionality of power generating assets have notably changed. Considering the decline in the price of hydrocarbon fuel on the global market, the efficiency of combined-cycle gas-turbine plants in the European part of Russia is growing in comparison with nuclear power plants. Capital investments in the construction of nuclear power plants have also increased as a result of stiffening the safety requirements. In view of this, there has been an increasing interest in exploration of effective lines of development of generating assets in the European part of Russia, taking consideration of the conditions that may arise in the nearest long-term perspective. In particular, the assessment of comparative efficiency of developing combined-cycle gas-turbine plants (operating on natural gas) in the European part of Russia and nuclear power plants is of academic and practical interest. In this article, we analyze the trends of changes in the regional price of hydrocarbon fuel. Using the prognosis of net-weighted import prices of natural gas in Western European countries—prepared by the International Energy Agency (IEA) and the Energy Research Institute of the Russian Academy of Sciences (ERIRAS)—the prices of natural gas in the European part of Russia equilibrated with import prices of this heat carrier in Western Europe were determined. The methodology of determining the comparative efficiency of combined-cycle gas turbine plants (CCGT) and nuclear power plants (NPP) were described; based on this, the possible development of basic CCGTs and NPPs with regard to the European part of Russia for various scenarios in the prognosis of prices of gaseous fuel in a broad range of change of specific investments in the given generating sources were assessed, and the extents of their comparative efficiency were shown. It was proven that, at specific investments in the construction of new NPPs in the amount of 5000 dollars/kW, nuclear

    The objective of this research is to determine the use of production factors in 3 different types of sunflower production with respect to orobanche resistance in the agricultural enterprises in Thrace Region which is located at European continent of Turkey. The data used in this research have been obtained through questionnaire technique from 571 agricultural enterprises which were determined by Stratified Random Sampling Method in 2009. It has been reached to the highest yield by 189.30 kg da-1 and the highest gross profit by 37.91 US$ da-1 in the production of sunflower, resistant to orobanche. In the research, it has been determined that the rate of soil testing among the sunflower producers is considerably low and almost the whole of the production has been made under rainfed conditions. As a result of the research, it has been concluded that orobanche resistant sunflower, which has higher water productivity than other cultivars by 367.13 g m/sup 3/, will have a higher proportion in the sunflower cultivation areas in future because of its higher contribution to producer welfare.

    Wildfires can have an important impact on regional air quality as they are large and intermittent sources of primary particulates, secondary aerosols, and ozone precursors. As part of an ongoing analysis on the effects of global change upon US air quality, we report results for current and future decade simulations of the inter-relationship among climate change, wildfires and air quality. The results are reported for the Northwest, Southwest, and Central Rockies regions of the US. Meteorological fields from the ECHAM5 global climate model for the IPCC A1B scenario were downscaled using the Weather Research Forecast (WRF) model to drive the MEGAN biogenic emissions model, a stochastic fire occurrence model, Fire Simulation Builder (FSB), and the CMAQ chemical transport model to predict ozone and aerosol concentrations. Simulations were completed for two nested domains covering most of the northern hemisphere from eastern Asia to North America at 220 km horizontal resolution (hemispheric domain) and covering the continental US at 36 km resolution (CONUS). Sensitivity studies were conducted for representative summer periods with fire occurrence generated from FSB within the current (1995-2004) and future decade (2045-2054) and using current decade historical fire data obtained from the Bureau of Land Management Database. Results are reported in terms of the effects of global change upon fire occurrence, fire plume transport and PM and ozone pollutant levels.

  13. The Current Mental State of School Students in Online Learning Conditions

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available This article discusses the results of a study of actual mental state of high school students who are active subjects of career self-determination in terms of interactive learning. There are four groups of methods of interactive training: psychological training, art therapy, cognitive, and game training. The main task, which is solved by a researcher in a formative experiment with the use of each of these methods, is to establish significant differences in health, activity and mood as the indicators of current mental state of students in the classroom. As a result, we found that the most significant improvements in the current mental state takes place when using art and game therapy, so these techniques should be used in groups of students with low motivation to work, as well as in the adverse psychological climate. Less significant was the improvement of the current mental state after psychological training due to the fact that this method allow to update and seek solutions to the most important intrapersonal issues and require the implementation of a deeper reflection

    2013-10-25

    A new and better taste avoidance conditioning paradigm for Lymnaea has been developed that replaces the previously used tactile unconditional stimulus (US) with an brief electrical stimulus (1000V, 80μA), while continuing to use a sucrose application to the lips as the conditional stimulus (CS). With 15 paired CS-US presentations on a single day, we were able to elicit both short-term memory (STM) and long-term memory (LTM). The LTM persisted for at least one week. While STM was elicited with 5, 8, or 10 paired presentations of the CS-US on a single day, LTM was not. The new US used here was more consistent than the previously used US, and this stimulus consistency may explain why 15 paired CS-US presentations now result in LTM formation.

    Objective The aim of the present study was to audit the current use of medical records to determine completeness and concordance with other sources of medical information. Methods Medical records for 40 patients from each of five Melbourne major metropolitan hospitals were randomly selected (n=200). A quantitative audit was performed for detailed patient information and medical record keeping, as well as data collection, storage and utilisation. Using each hospital's current online clinical database, scanned files and paperwork available for each patient audited, the reviewers sourced as much relevant information as possible within a 30-min time allocation from both the record and the discharge summary. Results Of all medical records audited, 82% contained medical and surgical history, allergy information and patient demographics. All audited discharge summaries lacked at least one of the following: demographics, medication allergies, medical and surgical history, medications and adverse drug event information. Only 49% of records audited showed evidence the discharge summary was sent outside the institution. Conclusions The quality of medical data captured and information management is variable across hospitals. It is recommended that medical history documentation guidelines and standardised discharge summaries be implemented in Australian healthcare services. What is known about this topic? Australia has a complex health system, the government has approved funding to develop a universal online electronic medical record system and is currently trialling this in an opt-out style in the Napean Blue Mountains (NSW) and in Northern Queensland. The system was originally named the personally controlled electronic health record but has since been changed to MyHealth Record (2016). In Victoria, there exists a wide range of electronic health records used to varying degrees, with some hospitals still relying on paper-based records and many using scanned medical records

    Controversy remains around acceptable surgical delay of acute hip fractures with current guidelines ranging from 24 to 48 h. Increasing healthcare costs force us to consider the economic burden as well. We aimed to evaluate the adjusted effect of surgical delay for hip fracture surgery on early mortality, healthcare costs and readmission rate. We hypothesized that shorter delays resulted in lower early mortality and costs. In this retrospective cohort study 2573 consecutive patients aged ≥50 years were included, who underwent surgery for acute hip fractures between 2009 and 2017. Main endpoints were thirty- and ninety-day mortality, total cost, and readmission rate. Multivariable regression included sex, age and ASA score as covariates. Thirty-day mortality was 5% (n = 133), ninety-day mortality 12% (n = 304). Average total cost was €11960, dominated by hospitalization (59%) and honoraria (23%). Per 24 h delay, the adjusted odds ratio was 1.07 (95% CI 0.98-1.18) for thirty-day mortality, 1.12 (95% CI 1.04-1.19) for ninety-day mortality, and 0.99 (95% CI = 0.88-1.12) for readmission. Per 24 h delay, costs increased with 7% (95% CI 6-8%). For mortality, delay was a weaker predictor than sex, age, and ASA score. For costs, delay was the strongest predictor. We did not find clear cut-points for surgical delay after which mortality or costs increased abruptly. Despite only modest associations with mortality, we observed a steady increase in healthcare costs when delaying surgery. Hence, a more pragmatic approach with surgery as soon as medically and organizationally possible seems justifiable over rigorous implementation of the current guidelines.

  1. A Novel Distributed Economic Model Predictive Control Approach for Building Air-Conditioning Systems in Microgrids

    Directory of Open Access Journals (Sweden)

    Xinan Zhang

    2018-04-01

    Full Text Available With the penetration of grid-connected renewable energy generation, microgrids are facing stability and power quality problems caused by renewable intermittency. To alleviate such problems, demand side management (DSM of responsive loads, such as building air-conditioning system (BACS, has been proposed and studied. In recent years, numerous control approaches have been published for proper management of single BACS. The majority of these approaches focus on either the control of BACS for attenuating power fluctuations in the grid or the operating cost minimization on behalf of the residents. These two control objectives are paramount for BACS control in microgrids and can be conflicting. As such, they should be considered together in control design. As individual buildings may have different owners/residents, it is natural to control different BACSs in an autonomous and self-interested manner to minimize the operational costs for the owners/residents. Unfortunately, such “selfish” operation can result in abrupt and large power fluctuations at the point of common coupling (PCC of the microgrid due to lack of coordination. Consequently, the original objective of mitigating power fluctuations generated by renewable intermittency cannot be achieved. To minimize the operating costs of individual BACSs and simultaneously ensure desirable overall power flow at PCC, this paper proposes a novel distributed control framework based on the dissipativity theory. The proposed method achieves the objective of renewable intermittency mitigation through proper coordination of distributed BACS controllers and is scalable and computationally efficient. Simulation studies are carried out to illustrate the efficacy of the proposed control framework.

    Water-human systems are coupled and display co-evolutionary dynamics influenced by society's values and preference. This has been observed in the Murrumbidgee basin, Australia where water usage initially focused on agriculture production and until mid-1990's favoured agriculture. This turned around as society became more concerned about the degradation of ecosystems and ultimately water was reallocated back towards the environment. This new water management adversely impacted the agriculture sector and created economic stress in the basin. The basin communities were able to transform and cope with water allocation favouring the environment through sectoral transformation facilitated by movement of capital in a free economy, supported by appropriate strategies and funding. This was helped by the adaptive capacity of people through reemployment in other economic sectors of the basin economy, unemployment for a period of time and migration out of the basin, and crop diversification. This study looks to the future and focuses on how water managers could be informed and prepare for un-foreseen issues coming out of societies changing values and preferences and emerging as different systems in the basin interact with each other at different times and speed. The issues of this type that concern the Murray Darling Basin Authority include a renewed focus and priority on food production due to food scarcity; increased impact and frequency of natural disasters (eg. climate change); regional economic diversification due to the growth of peri-urban development in the basin; institutional capacity for water reform due to new political paradigms (eg. new water sharing plans); and improvement in science and technology (eg. farm practices, water efficiency, water reuse). To undertake this, the study uses a coupled socio-hydrological dynamical system that model the major drivers of changing economic conditions, society values and preference, climatic condition and science and

    2010-08-01

    Full Text Available There is good reason to be concerned about the long-term implications of the current crisis for the reproduction of contemporary social formations. Thus there is an urgent need to understand it character, especially its distinctive features. This article identifies profound ambiguities in valuing assets as new and key economic features of this crisis, ambiguities traceable to the dominant, “computationalist” computing used to develop new financial instruments. After some preliminaries, the article identifies four specific ways in which computerization of finance is generative of crisis. It then demonstrates how computationalist computing is linked to other efforts to extend commodification based on the ideology of so-called “intellectual property” (IP. Several other accounts for the crisis are considered and then demonstrated to have less explanatory value. After considering how some commons-oriented (e.g., Free/Libre and/or Opening Source Software development projects forms of computing also undermine the IP project, the article concludes with a brief discussion of what research on Socially Robust and Enduring Computing might contribute to fostering alternative, non-crisis generative ways to compute.

    Full Text Available This work highlights the economic crisis problem that affects most states of the world, the crime problem that the society is facing, namely the human trafficking and in particular the child trafficking. This theme is particularly important in the context of amplifying the organized crime, it increasingly concerns the modern society and implicitly the specialists engaged in research of the phenomenon and for preventing and combating it. This paper is an analysis of the current financial crisis impact on human trafficking and the level of response that the society is ready to give through the regulatory framework, specialized institutions and their staff. The analysis concluded that Romania, as a result of its alignment with the acquis communautaire, is now a modern legislative and institutional system in preventing and combating trafficking in human beings. However, there is a need for legislative amendments in order to have a greater effectiveness in prevention and control measures, which represents a milestone in addressing other related issues. This study is also a warning for specialists to deepen their research for improving the prevention and combating trafficking in human beings which tends to grow.

    The Democratic Republic of the Congo is today one of the poorest countries in the world; the health status of the population ranks among the worst in Sub-Saharan Africa. Public health services charge user fees and drug prices. Since 2008, north-eastern Congo is facing a guerrilla war. Malteser International is assisting with free health care for internally displaced persons as well as the general population. Before the incursion the health system was based on user fees. The aim of this study was to determine the socio-economic conditions of the population and to assess their ability to contribute to health care. Heads of 552 randomly selected households in 23 clusters in two health zones were interviewed using a standardised questionnaire. The demographic description and socio-economic conditions of the study population were homogenous. Major source of income was agriculture (57%); 47% of the households earned less than US$ 5.5/week. Ninety-two percent of the interviewed households estimated that they would be able to contribute to consultation fees (maximum amount of US$ 0.27) and 79% to the drug prices (maximum amount of US$ 1.10). Six percent opted for free consultations and 19% for free drugs. Living conditions were very basic; the estimated income of the study population was low. Almost half of the population perceived their current living situation as fairly good/good. More than 90% of the study population estimated to be able to contribute to consultation fees and 80% to drug prices. As a result Malteser International suggested introducing flat-rates for health care services. Once the project ends, the population will have to pay again for their health service. One solution would be the introduction of a health care financing system with the goal to reach universal coverage to health care.

    It is shown that, if the maximum of the magnetic field strength on a magnetic surface in a threedimensional magnetic confinement configuration with stellarator symmetry constitutes a line that is orthogonal to the field lines and crosses the symmetry line, then the bootstrap current density is smaller compared to that in quasi-axisymmetric (qa) [J.

  9. Being born under adverse economic conditions leads to a higher cardiovascular mortality rate later in life: evidence based on individuals born at different stages of the business cycle.

    2011-05-01

    We connect the recent medical and economic literatures on the long-run effects of early-life conditions by analyzing the effects of economic conditions on the individual cardiovascular (CV) mortality rate later in life, using individual data records from the Danish Twin Registry covering births since the 1870s and including the cause of death. To capture exogenous variation of conditions early in life, we use the state of the business cycle around birth. We find significant negative effects of economic conditions around birth on the individual CV mortality rate at higher ages. There is no effect on the cancer-specific mortality rate. From variation within and between monozygotic and dizygotic twin pairs born under different conditions, we conclude that the fate of an individual is more strongly determined by genetic and household-environmental factors if early-life conditions are poor. Individual-specific qualities come more to fruition if the starting position in life is better.

  10. Possibilities of Monitoring the Technical Condition of the Combustion Engine with Starter Load Current

    Full Text Available This article deals with the verification of relations between the electric current of engine starter and tightness of the combustion chamber and the possibility of its use for the evaluation of the state in terms of engine wear. Engine wear is closely related to the quality of fuel combustion and also with the amount of produced harmful emissions. On this basis, it would be possible to extend the technical requirements of the protocol OBD to include the indirect control of engine wear. To meet the objectives set out above measurement was carried out by a petrol engine, which was located in the vehicle Škoda Felicia Combi GLX 1.3 The whole measurement was divided into several parts. The first measurement was carried out on the abovementioned motor without simulating leakage. The second measurement was performed when the leakage of one cylinder was simulated. Simulated leakage was conducted at removing the spark plugs. Other measurements simulated “mild” leak of the whole engine – all cylinders. Leakage was implemented by loosing all the spark plugs about 8 turns against full tightening with the appropriate torque. The last, fourth measurement simulates a “large” leaks of engine cylinders. This leakage was induced by removing all the spark plugs from all cylinders. As the measurement results showed leakage of one cylinder, and also the whole engine is reflected not only in the individual amplitude of the starter current, but also the shape of the entire curve.

  11. Secondary current properties generated by wind-induced water waves in experimental conditions

    Full Text Available Secondary currents such as the Langmuir circulation are of high interest in natural rivers and the ocean because they have striking impacts on scour, sedimentation, and mass transport. Basic characteristics have been well-studied in straight open-channel flows. However, little is known regarding secondary circulation induced by wind waves. The presented study describes the generation properties of wind waves observed in the laboratory tank. Wind-induced water waves are known to produce large scale circulations. The phenomenon is observed together with high-speed and low-speed streaks, convergence and divergence zones, respectively. Therefore, it is important to determine the hydrodynamic properties of secondary currents for wind-induced water waves within rivers and lakes. In this study, using two high-speed CMOS cameras, stereoscopic particle image velocimetry (PIV measurements were conducted in order to reveal the distribution of all three components of velocity vectors. The experiments allowed us to investigate the three-dimensional turbulent structure under water waves and the generation mechanism of large-scale circulations. Additionally, a third CMOS camera was used to measure the spanwise profile of thefree-surface elevation. The time-series of velocity components and the free-surface were obtained simultaneously. From our experiments, free-surface variations were found to influence the instantaneous velocity distributions of the cross-sectional plane. We also considered thegeneration process by the phase analysis related to gravity waves and compared the contribution of the apparent stress.

  12. The restructuring of the distributive relations as necessary condition of socio-economic development of Russian regions

    2011-03-01

    Full Text Available The problems of inequality and poverty in the population dynamics are reviewed. Advantages and disadvantages of poverty indicators used in the statistics of the Russian Federation - in comparison with those in the statistics of the Soviet Union and the EU - are analyzed. A curve of income distribution in Russia in comparison with European standards is proposed. Particular attention is paid to the mechanisms of formation and redistribution of income from which only the rich layers of the population are currently benefiting. For the dynamics of income of the poorest layers of the population, a tendency to reduce is characteristic. To change the situation, institutional reforms in the sphere of distribution relations are required, as some groups have institutional advantages in comparison with others. I.e. it is necessary to change the view of backward and forward linkages of social inequality and socio-economic growth. For this purpose, we introduce the concept of the functional boundaries of income for different kinds of economic, social and demographic behavior of the population. Accordingly, the inequality should be divided into normal and excessive, in terms of the feasibility of human capabilities. Excessive inequality, in turn, can be surmounted by the introduction of progressive taxation.

  13. Technical review and evaluation of the economics of water desalination: Current and future challenges for better water supply sustainability

    KAUST Repository

    Ghaffour, Noreddine

    2013-01-01

    Desalination capacity has rapidly increased in the last decade because of the increase in water demand and a significant reduction in desalination cost as a result of significant technological advances, especially in the reverse osmosis process. The cost of desalinated seawater has fallen below US$0.50/m3 for a large scale seawater reverse osmosis plant at a specific location and conditions while in other locations the cost is 50% higher (US$1.00/m3) for a similar facility. In addition to capital and operating costs, other parameters such as local incentives or subsidies may also contribute to the large difference in desalted water cost between regions and facilities. Plant suppliers and consultants have their own cost calculation methodologies, but they are confidential and provide water costs with different accuracies. The few existing costing methodologies and software packages such as WTCost© and DEEP provide an estimated cost with different accuracies and their applications are limited to specific conditions. Most of the available cost estimation tools are of the black box type, which provide few details concerning the parameters and methodologies applied for local conditions. Many desalination plants built recently have greater desalinated water delivery costs caused by special circumstances, such as plant remediation or upgrades, local variation in energy costs, and site-specific issues in raw materials costs (e.g., tariffs and transportation). Therefore, the availability of a more transparent and unique methodology for estimating the cost will help in selecting an appropriate desalination technology suitable for specific locations with consideration of all the parameters influencing the cost. A techno-economic evaluation and review of the costing aspects and the main parameters influencing the total water cost produced by different desalination technologies are herein presented in detail. Some recent developments, such as the increase of unit capacity

    We applied a 1-dimensional lake model developed to simulate deep mixing related to thermobaric instabilities in temperate lakes to Crater Lake, a 590-m deep caldera lake in Oregon's Cascade Range known for its stunning deep blue color and extremely clear water, in order to determine the frequency of deep water renewal in future climate conditions. The lake model was calibrated with 6 years of water temperature profiles, and then simulated 10 years of validation data with an RMSE ranging from 0.81°C at 50 m depth to 0.04°C at 350-460 m depth. The simulated time series of heat content in the deep lake accurately captured extreme years characterized by weak and strong deep water renewal. The lake model uses wind speed and lake surface temperature (LST) as boundary conditions. LST projections under six climate scenarios from the CMIP5 intermodel comparison project (2 representative concentration pathways X 3 general circulation models) were evaluated with air2water, a simple lumped model that only requires daily values of downscaled air temperature. air2water was calibrated with data from 1993-2011, resulting in a RMSE between simulated and observed daily LST values of 0.68°C. All future climate scenarios project increased water temperature throughout the water column and a substantive reduction in the frequency of deepwater renewal events. The least extreme scenario (CNRM-CM5, RCP4.5) projects the frequency of deepwater renewal events to decrease from about 1 in 2 years in the present to about 1 in 3 years by 2100. The most extreme scenario (HadGEM2-ES, RCP8.5) projects the frequency of deepwater renewal events to be less than 1 in 7 years by 2100 and lake surface temperatures never cooling to less than 4°C after 2050. In all RCP4.5 simulations the temperature of the entire water column is greater than 4°C for increasing periods of time. In the RCP8.5 simulations, the temperature of the entire water column is greater than 4°C year round by the year 2060 (HadGEM2

    Compulsive buying is characterized by frequent excessive purchasing of items that are primarily not needed or used. The compulsive buying behavior results in mental, social, financial and often legal problems. Although compulsive buying affects a significant percentage of the general population and has received increasing attention in research, it has largely been ignored in clinical practice. Compulsive buying disorder is currently conceptualized as an"impulse control disorder not otherwise specified". However, the appropriate classification continues to be debated. Compulsive buying is associated with significant psychiatric co-morbidity, especially with depressive, anxiety, obsessive-compulsive, substance use, personality, and other impulse control disorders. Small controlled trials failed to confirm the efficacy of antidepressants in the treatment of compulsive buying disorder, whereas early evidence suggests that cognitive behavioral therapy is helpful in alleviating compulsive buying symptoms. Further research is needed to establish a better understanding of etiology, classification, and treatment strategies.

  16. Health Effects of Unemployment in Denmark, Norway and Sweden 2007-2010: Differing Economic Conditions, Differing Results?

    This article investigates short-term health effects of unemployment for individuals in Denmark, Norway, and Sweden during an economic downturn (2007-2010) that hit the Scandinavian countries with diverging strength. The longitudinal part of the European Union Statistics on Income and Living Conditions (EU-SILC) data material is analyzed, and results from generalized least squares estimation indicate that Denmark is the only Scandinavian country in which health status deteriorated among the unemployed. The individual-level (and calendar year) fixed-effect results confirm the negative relationship between unemployment and health status in Denmark. This result is robust across different subsamples, model specifications, and changes in both the dependent and independent variable. Health status deteriorated especially among women and people in prime working age (30-59 years). There is, however, only scant evidence of short-term health effects among the recently unemployed in Norway and Sweden. The empirical findings are discussed in light of: (1) the adequacy of the unemployment insurance system, (2) the likelihood of re-employment for the displaced worker, and (3) selection patterns into and out of employment in the years preceding and during the economic downturn. © The Author(s) 2016.

    Full Text Available Purpose: the main purpose of this article is to identify « growth points» of economic growth in the regions, determine their type, and assess the conditions for their development. Methods: the main feature of this study is to obtain an expert assessment of the qualitative aspects of regional development. The main source of empirical data was an online survey conducted by the authors in 2016. Results: the study identified potential «growth points» in five regions of the Russian Federation and determined their nature according to the idea of modernizing the socio-economic environment. The selected points allow to develop the potential of the region horizontally. However, there are certain problems that hinder this development and they have been identified. Conclusions and Relevance: at the moment, the identified «growth points» can not be classified as information or intellectual, but in all regions there is the possibility of activating such industries. The «growth points» allocated by experts are still potential, because their technical, technological and innovative components have medium level of development. «Growth points» in the Republic of Sakha and the Nizhny Novgorod region have a greater modernization activity. Such expertise can be used by local authorities to adjust development vectors and strategies. It can also be an element of monitoring the socioeconomic development of regions.

    Highlights: • Transesterification in supercritical methanol, ethanol and 1-propanol investigated. • Effect of alcohol, reaction temperature, pressure and time on yields analyzed. • Temperature has the highest impact on yield, followed by time and pressure. • Direct material and energy costs for each of the production alternatives estimated. • Lowest costs are achieved at highest yields even at very low oil prices. - Abstract: Experiments with transesterification of rapeseed oil in supercritical alcohols (methanol, ethanol and 1-propanol) were carried out in a batch reactor at various reaction temperatures (250–350 °C), working pressure (8–12 MPa), reaction time, and constant 42:1 alcohol to oil molar ratio. Influence of different alcohols and reaction conditions on biodiesel yield was investigated using linear multiple regression models. Temperature had the highest impact on yields, followed by reaction time and pressure. With increased molecular weight of alcohols, relative importance of temperature for explanation of yields decreased and relative importance of time and pressure increased. Economic assessment has revealed that transesterification in supercritical methanol has the lowest direct material and energy costs. Yield has crucial impact on process economics. Direct costs decrease with increase in biodiesel yields. Even at very low prices of oil feedstock the lowest cost is achieved at the highest yield

    Results from the standard quasilinear theory of ion-acoustic and Langmuir plasma microturbulence are incorporated into the kinetic theory of the electron distribution function. The theory is then applied to high current discharges and laser-produced plasmas, where either the current flow or the nonlinear laser-light absorption acts, respectively, as the energy source for the microturbulence. More specifically, the theory is applied to a selenium plasma, whose charge state is determined under conditions of collisional-radiative equilibrium, and plasma conditions are found under which microturbulence strongly influences the electron kinetics. In selenium, we show that this influence extends over a wide range of plasma conditions. For ion-acoustic turbulence, a criterion is derived, analogous to one previously obtained for laser heated plasmas, that predicts when Ohmic heating dominates over electron-electron collisions. This dominance leads to the generation of electron distributions with reduced high-energy tails relative to a Maxwellian distribution of the same temperature. Ion-acoustic turbulence lowers the current requirements needed to generate these distributions. When the laser heating criterion is rederived with ion-acoustic turbulence included in the theory, a similar reduction in the laser intensity needed to produce non-Maxwellian distributions is found. Thus we show that ion-acoustic turbulence uniformly (i.e., by the same numerical factor) reduces the electrical and heat conductivities, as well as the current (squared) and laser intensity levels needed to drive the plasma into non-Maxwellian states

    The paper designs a new wind-water cooling and heating water conditioner system, connects cooling tower with heat recovery device, which uses cooling water to completely remove the heat that does not need heat recollection, in order to ensure that the system can work efficiently with higher performance coefficient. After the test actual engineering operation, the system’s maximum cooling coefficient of performance can reach 3.5. Its maximum comprehensive coefficient of performance can reach 6.5. After the analysis of its economic and environmental, we conclude that the new system can save 89822 kw per year. It reflects energy-saving and environmental benefits of the cold and hot water air conditioning system.

    Busulfan (BU) used as cytoreductive conditioning prior to hematopoietic stem cell transplantation (HSCT) is available as intravenous (IV) and oral (O) preparation. IV-BU has clinical advantages associated with relevant incremental costs. The aim was to determine the economic impact of IV-BU versus O-BU in adult HSCT recipients from a German health care providers' perspective. A budget-impact model (BIM) including costs and risks for oral mucositis (OM), infection with OM, and hepatic sinusoidal obstruction syndrome (SOS) was developed. Model inputs are literature data comparing clinical effects of IV-BU versus O-BU and German cost data (conditioning therapy, treatment of OM, infections, SOS without/with multiorgan failure) from literature and tariff lists. Base case calculations resulted the following: total costs of adverse events were €86,434 with O-BU and €44,376 with IV-BU for ten patients each. Considering costs of adverse events and drugs, about €5840 for ten patients receiving IV-BU are saved. Sensitivity analyses were conducted in several ways. Cost savings range between €4910 and €12,640 per ten patients for all adverse events and €2070 or €1140 per ten patients considering SOS only. Drug treatment of SOS and treatment of multiorgan failure during severe SOS are major cost drivers. Worst case scenario calculations (assuming -25% risk of all adverse events for O-BU and +25% for IV-BU) yield up to €27,570 per ten patients with IV-BU. Considering costs of adverse events and drugs, IV-BU is the dominant alternative from a German providers' perspective. For more comprehensive economic evaluations, additional epidemiological data, evidence on clinical outcomes, patient-reported outcomes, and treatment patterns are needed.

    Experimental date from low-energy nuclear reactions (LENR) in condensed media are presented. The nuclear reactions products were found in solid cathode media used in glow discharge. Apparently, the nuclear reactions were initiated when bombarding the cathode surface by plasma ions with the energy of 1.0 - 2.0 keV. Excess heat from a high current glow discharge reaction in D{sub 2}, Xe, and Kr using cathodes already charged with preliminary deuterium-charged Pd and Ti cathode samples are given. Excess heat up to 10-15 W and efficiency up to 130% were recorded under the experiments for Pd cathode samples in D{sub 2} discharge. Excess heat up to 5 W and efficiency up to 150% were recorded for Pd cathodes that were charged with deuterium before the run, in Xe and Kr discharges.

Soft X-ray radiation from the solid-state cathode with the intensity up to 0.01 Gy/s was recorded in experiments with discharges in H{sub 2}, D{sub 2}, Ar, Xe, and Kr. The X-ray radiation was observed in bursts of up to 10{sup 6} photons, with up to 10{sup 5} bursts per second while the discharge was formed and within 100 ms after turning off the discharge current. The results of the X-ray radiation registration showed that the excited energy levels have a lifetime up to 100 ms or more, and the energy of 1.2 - 2.5 keV. A possible mechanism for producing excess heat and nuclear transmutation reactions in the solid medium with the excited energy levels is considered.

  5. Modelling of the reactive sputtering process with non-uniform discharge current density and different temperature conditions

    2009-01-01

    The majority of current models of the reactive magnetron sputtering assume a uniform shape of the discharge current density and the same temperature near the target and the substrate. However, in the real experimental set-up, the presence of the magnetic field causes high density plasma to form in front of the cathode in the shape of a toroid. Consequently, the discharge current density is laterally non-uniform. In addition to this, the heating of the background gas by sputtered particles, which is usually referred to as the gas rarefaction, plays an important role. This paper presents an extended model of the reactive magnetron sputtering that assumes the non-uniform discharge current density and which accommodates the gas rarefaction effect. It is devoted mainly to the study of the behaviour of the reactive sputtering rather that to the prediction of the coating properties. Outputs of this model are compared with those that assume uniform discharge current density and uniform temperature profile in the deposition chamber. Particular attention is paid to the modelling of the radial variation of the target composition near transitions from the metallic to the compound mode and vice versa. A study of the target utilization in the metallic and compound mode is performed for two different discharge current density profiles corresponding to typical two pole and multipole magnetics available on the market now. Different shapes of the discharge current density were tested. Finally, hysteresis curves are plotted for various temperature conditions in the reactor.

    This work introduces an inductive energy storage (IES) scheme which aims pulsed-power conditioning at multi- MJ energies. The key element of the scheme represents an additional plasma volume, where a magnetically accelerated wire array is used for inductive current switching. This plasma acceleration volume is connected in parallel to a microsecond capacitor bank and to a 100-ns current ruse-time useful load. Simple estimates suggest that optimized scheme parameters could be reachable even when operating at ultra-high currents. We describe first proof-of-principle experiments carried out on GIT12 generator at the wire-array current level of 2 MA. The obtained confirmation of the concept consists in generation of a 200 kV voltage directly at an inductive load. This load voltage value can be already sufficient to transfer the available magnetic energy into kinetic energy of a liner at this current level. Two-dimensional modeling with the radiational MHD numerical tool Marple confirms the development of inductive voltage in the system. However, the average voltage increase is accompanied by short-duration voltage drops due to interception of the current by the low-density upstream plasma. Upon our viewpoint, this instability of the current distribution represents the main physical limitation to the scheme performance

    Condition monitoring of rotating machine is essential to guarantee the safety operation as well as to improve the efficiency of nuclear power plants operations. One of the promising condition monitoring techniques which has been preferred currently since it is simple, non-invasive and inexpensive is Motor Stator Signature Analysis (MCSA). However, the investigation of the MCSA technique using a compact, low cost, and having industrial class hardware which is capable for nuclear power plant applications has been limited. The research is aimed to develop condition monitoring method based on MCSA utilizing a compact industrial class for nuclear power plant. The investigation includes development of condition monitoring based on real-time FPGA-CompatRIO hardware, development of a custom built display module for early warning system, testing of the monitoring hardware, fault frequency analysis of electric motors including the performances of fault detections. The condition monitoring system is able to execute a fault detection task around 164 ms, to recognize accurately fault frequencies of stator shorted turn for about 75%, broken rotor bar around 95%, eccentricity 65%, mechanical misalignment 85%, including supply voltage unbalances 100%. The condition monitoring system based on its performance assessments could become a suitable alternative not only for rotating machines but also condition monitoring for other nuclear reactor components.

    In this work both detection of the beginning of dry-band arcing and correlating the average value of leakage current (LC) with non-ceramic insulator surface damage have been investigated. Silicone rubber insulators were tested in salt-fog under different voltage and conductivity levels. The autocorrelation function (ACF) was calculated for both the fundamental and third harmonic components of LC during the early aging period (EAP). It has been observed that distinct differences exist in the behavior of both the fundamental and that of the third harmonic components of the LC during EAP. Although the fundamental component of the LC begins to grow immediately after starting the test, the third harmonic requires a much longer period of time to begin. Dry-band arcing is highly correlated with distortion in the LC and hence to its third harmonic component. But it has been observed that the level of the fundamental component of LC at which the third harmonic component started to increase is different from one case to another. As such, it is more appropriate to use the ACF of the third harmonic component of LC as an indication of dry-band arcing rather than a simple threshold value. Moreover, the average value of LC during late aging period (LAP) was correlated with the damage of non-ceramic insulators. It has been found that the average level of both the fundamental and third harmonic component of LC is well correlated with the different degrees of damage of non-ceramic insulators' surface.

    Efficacy of four commercial biocidal products (noted A to D), using manufacturers' recommendations, and a contact time of 30minutes, were evaluated in the purpose of standard SR EN1657: 2006 adapted. Were used four strains, two as reference: Aspergillus brasiliensis (niger) (ATCC 16404) and Candida albicans (ATCC 10231), and two isolates: Aspergillus flavus and respectively Aspergillus fumigatus. The inoculum plates containing Malt Extract Agar (MEA) were incubated 48h for C. albicans and 72hours for Aspergillus spp. The standard SR EN1657: 2006 adapted was conducted in two phases: the test cultures preparation and the method validation. Method validation included: the control of experimental conditions and of neutralizant solution, and the method verification. Results revealed that three from the four tested products (A, B and D) had exerted biocidal effect on the studied strains at the recommended concentrations, the registered CFU values being reduced by more than 4 log 10 , conversely in the case of the product (C), applied against A. fumigatus at the recommended concentration of 2%, the biocidal effect was not detected, fact confirmed also by the CFU's value (3.59 log 10 ). The biocide retested at a greater concentration (of 5%), showed a biocidal effect against A. fumigatus after 30minutes, the CFU value being reduced, by more than 5.29 log 10 , evidencing the resistance emergence of A. fumigatus under the repeated pressure of biocides. It is re-confirming that merely the "chemical" defense measures to defuse the fungi's strategies become unproductive. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    This study presents an extensive database on groundwater conditions in and around Devils Postpile National Monument. The database contains chemical analyses of springs and the monument water-supply well, including major-ion chemistry, trace element chemistry, and the first information on a list of organic compounds known as emerging contaminants. Diurnal, seasonal, and annual variations in groundwater discharge and chemistry are evaluated from data collected at five main monitoring sites, where streams carry the aggregate flow from entire groups of springs. These springs drain the Mammoth Mountain area and, during the fall months, contribute a significant fraction of the San Joaquin River flow within the monument. The period of this study, from fall 2012 to fall 2015, includes some of the driest years on record, though the seasonal variability observed in 2013 might have been near normal. The spring-fed streams generally flowed at rates well below those observed during a sequence of wet years in the late 1990s. However, persistence of flow and reasonably stable water chemistry through the recent dry years are indicative of a sizeable groundwater system that should provide a reliable resource during similar droughts in the future. Only a few emerging contaminants were detected at trace levels below 1 microgram per liter (μg/L), suggesting that local human visitation is not degrading groundwater quality. No indication of salt from the ski area on the north side of Mammoth Mountain could be found in any of the groundwaters. Chemical data instead show that natural mineral water, such as that discharged from local soda springs, is the main source of anomalous chloride in the monument supply well and in the San Joaquin River. The results of the study are used to develop a set of recommendations for future monitoring to enable detection of deleterious impacts to groundwater quality and quantity

  16. A global assessment of gross and net land change dynamics for current conditions and future scenarios

    The consideration of gross land changes, meaning all area gains and losses within a pixel or administrative unit (e.g. country), plays an essential role in the estimation of total land changes. Gross land changes affect the magnitude of total land changes, which feeds back to the attribution of biogeochemical and biophysical processes related to climate change in Earth system models. Global empirical studies on gross land changes are currently lacking. Whilst the relevance of gross changes for global change has been indicated in the literature, it is not accounted for in future land change scenarios. In this study, we extract gross and net land change dynamics from large-scale and high-resolution (30-100 m) remote sensing products to create a new global gross and net change dataset. Subsequently, we developed an approach to integrate our empirically derived gross and net changes with the results of future simulation models by accounting for the gross and net change addressed by the land use model and the gross and net change that is below the resolution of modelling. Based on our empirical data, we found that gross land change within 0.5° grid cells was substantially larger than net changes in all parts of the world. As 0.5° grid cells are a standard resolution of Earth system models, this leads to an underestimation of the amount of change. This finding contradicts earlier studies, which assumed gross land changes to appear in shifting cultivation areas only. Applied in a future scenario, the consideration of gross land changes led to approximately 50 % more land changes globally compared to a net land change representation. Gross land changes were most important in heterogeneous land systems with multiple land uses (e.g. shifting cultivation, smallholder farming, and agro-forestry systems). Moreover, the importance of gross changes decreased over time due to further polarization and intensification of land use. Our results serve as an empirical database for

    Full Text Available This article focuses on development of Russian-Lithuanian economic ties. The research and practical significance of this study lies in the identification of the sources of modern Russian-Lithuanian economic cooperation and the prospects of future mutually beneficial economic relations. The first attempt at establishing economic relations was made in 1919. However, young Lithuanian Republic gravitated towards the West, severing ties with the Russian market. However, the initiatives of Lithuanian authorities did not result in successful state building, and the economic situation remained unchanged. The USSR leadership made an effort to improve the living conditions in post-war Lithuania. There were some mistakes made in the relations with the local population that resulted in Lithuanians’ resistance to sovietisation. However, in the conditions of post-war restoration of national economy and acute deficit of material and human resources, the Soviet leadership managed not only to reform and develop a socialistic economy in Lithuania but also to turn it into an industrial republic with developed agriculture and modern manufacturing facilities, whose major industries manufactured products used in nuclear and space technologies, aviation and navigation. The research shows that the post-Soviet period led to a dramatic change in Russian-Lithuanian economic relations; however, these relations retained potential for future development.

  19. Stabilizing the baseline current of a microbial fuel cell-based biosensor through overpotential control under non-toxic conditions.

    A MFC-based biosensor can act as online toxicity sensor. Electrical current is a direct linear measure for metabolic activity of electrochemically active microorganisms. Microorganisms gain energy from anodic overpotential and current strongly depends on anodic overpotential. Therefore control of anodic overpotential is necessary to detect toxic events and prevent false positive alarms. Anodic overpotential and thus current is influenced by anode potential, pH, substrate and bicarbonate concentrations. In terms of overpotential all factor showed a comparable effect, anode potential 1.2% change in current density per mV, pH 0.43%/mV, bicarbonate 0.75%/mV and acetate 0.8%/mV. At acetate saturation the maximum acetate conversion rate is reached and with that a constant bicarbonate concentration. Control of acetate and bicarbonate concentration can be less strict than control of anode potential and pH. Current density changes due to changing anode potential and pH are in the same order of magnitude as changes due to toxicity. Strict control of pH and anode potential in a small range is required. The importance of anodic overpotential control for detection of toxic compounds is shown. To reach a stable baseline current under nontoxic conditions a MFC-based biosensor should be operated at controlled anode potential, controlled pH and saturated substrate concentrations. 2009 Elsevier B.V.

    This work presents an algorithm control strategy denominated enthalpy economizer. The objective of this algorithm strategy is to determine the adequate fractions of outside and return air flowrates entering a cooling coil based on the analysis of the outside, return and supply air enthalpies, rather than on the analysis of the dry bulb temperatures. The proposed algorithm predicts the actual opening position of the outside and return air dampers in order to provide the lower mixing air enthalpy. First, the psychometrics properties of the outside and return air are calculated from actual measurements of the dry and wet bulb temperatures. Then, three distinct cases are analyzed: the enthalpy of the outside air is lower than the enthalpy of the supply air (free cooling); the enthalpy of the outside air is higher than the enthalpy of the return air; the enthalpy of the outside air is lower than the enthalpy of the return air and higher than the temperature of the supply air. Different outside air conditions were selected in order to represent typical weather data of Brazilians cities, as well as typical return air conditions. It was found that the enthalpy control strategy could promote an opportunity for energy savings mainly during mild nights and wintertime periods as well as during warm afternoons and summertime periods, depending on the outside air relative humidity. The proposed algorithm works well and can be integrated in some commercial automation software to reduce energy consumption and electricity demand. (author)

    The National Electrostatics Corporation's (NEC) Toroidal Volume Ion Source (TORVIS) source is known for exceptionally high proton currents with minimal service downtime as compared to traditional sputter sources. It has been possible to obtain over 150{mu}A of proton current from the source, with over 70{mu}A on the target stage. However, beam fluxes above {approx}1 Multiplication-Sign 10{sup 17}/m2-s may have many undesirable effects, especially for insulators. This may include high temperature gradients at the surface, sputtering, surface discharge, cracking or even disintegration of the sample. A series of experiments were conducted to examine the role of high current fluxes in a suite of ceramics and insulating materials. Results will show the optimal proton irradiation conditions and target mounting strategies needed to minimize unwanted macro-scale damage, while developing a procedure for conducting preliminary radiation experiments.

    2009-01-01

    Full Text Available Due to the current economic downturn, Singapore has experienced one of its most severe recessions since independence. The financial crisis, which caused a fall in prices at most of the world’s leading stock exchanges and a sharp decline in industrial production, has also had a negative impact on the city-state’s export-dependent economy. The analysis outlines the economic downturn and the decline of Singapore’s export economy since the beginning of the crisis in late 2008. Central to the analysis are questions regarding the social consequences of the current economic crisis and the amount of losses Singapore’s state-owned holding companies, Temasek and GIC, experienced when some of the world’s biggest investment banks, such as Merrill Lynch, went into bankruptcy.

  6. Automatic Condition Monitoring of Industrial Rolling-Element Bearings Using Motor’s Vibration and Current Analysis

    2015-01-01

    Full Text Available An automatic condition monitoring for a class of industrial rolling-element bearings is developed based on the vibration as well as stator current analysis. The considered fault scenarios include a single-point defect, multiple-point defects, and a type of distributed defect. Motivated by the potential commercialization, the developed system is promoted mainly using off-the-shelf techniques, that is, the high-frequency resonance technique with envelope detection and the average of short-time Fourier transform. In order to test the flexibility and robustness, the monitoring performance is extensively studied under diverse operating conditions: different sensor locations, motor speeds, loading conditions, and data samples from different time segments. The experimental results showed the powerful capability of vibration analysis in the bearing point defect fault diagnosis. The current analysis also showed a moderate capability in diagnosis of point defect faults depending on the type of fault, severity of the fault, and the operational condition. The temporal feature indicated a feasibility to detect generalized roughness fault. The practical issues, such as deviations of predicted characteristic frequencies, sideband effects, time-average of spectra, and selection of fault index and thresholds, are also discussed. The experimental work shows a huge potential to use some simple methods for successful diagnosis of industrial bearing systems.

    Development and optimisation of alternative strategies to reduce the use of classic chemical inputs for protection against diseases in vineyard is becoming a necessity. Among these strategies, one of the most promising consists in the stimulation and/or potentiation of the grapevine defence responses by the means of elicitors. Elicitors are highly diverse molecules both in nature and origins. This review aims at providing an overview of the current knowledge on these molecules and will highlight their potential efficacy from the laboratory in controlled conditions to vineyards. Recent findings and concepts (especially on plant innate immunity) and the new terminology (microbe-associated molecular patterns, effectors, etc.) are also discussed in this context. Other objectives of this review are to highlight the difficulty of transferring elicitors use and results from the controlled conditions to the vineyard, to determine their practical and effective use in viticulture and to propose ideas for improving their efficacy in non-controlled conditions.

  8. Socioeconomic Variation in the Effect of Economic Conditions on Marriage and Nonmarital Fertility in the United States: Evidence From the Great Recession.

    2015-12-01

    The United States has become increasingly characterized by stark class divides in family structure. Poor women are less likely to marry than their more affluent counterparts but are far more likely to have a birth outside of marriage. Recent theoretical and qualitative work at the intersection of demography and cultural sociology suggests that these patterns are generated because poor women have high, nearly unattainable, economic standards for marriage but make a much weaker connection between economic standing and fertility decisions. We use the events of the Great Recession, leveraging variation in the severity of the crisis between years and across states, to examine how exposure to worse state-level economic conditions is related to poor women's likelihood of marriage and of having a nonmarital birth between 2008 and 2012. In accord with theory, we find that women of low socioeconomic status (SES) exposed to worse economic conditions are indeed somewhat less likely to marry. However, we also find that unmarried low-SES women exposed to worse economic conditions significantly reduce their fertility; economic standing is not disconnected from nonmarital fertility. Our results suggest that economic concerns were connected to fertility decisions for low-SES unmarried women during the Great Recession.

    Full Text Available Economic evaluation of therapeutic sequences in the treatment of patients with chronic lymphocytic leukemia and coexisting conditionsIntroductionChronic lymphocytic leukemia (CLL is a chronic lymphoproliferative syndrome and it is the most common hematological malignancy in Western countries. It has a tendency to develop subsequent relapses, so affected patients are likely to undergo more than one line of treatment.MethodsRather than evaluating the cost-effectiveness of individual therapeutic agents, it becomes therefore recommendable for decision-makers to identify an optimal sequencing of such agents. A four-year cost-consequence analysis was conducted, comparing three alternative strategies for the first-line treatment of patients with previously untreated CLL and coexisting conditions: i obinutuzumab with chlorambucil (Obi-Clb, ii rituximab with chlorambucil (Rtx-Clb, and iii ofatumumab with chlorambucil (Ofa-Clb. Only drug costs were considered in the analysis.ResultsIn two trials, median time to next treatment (TTNT was longer in Obi-Clb (51.1 months as compared to Rtx-Clb (38.2 months or to Ofa-Clb (39.8 months. Therefore, during a 48-month time horizon, patients treated with Obi-Clb would maintain on average the first line treatment; on the contrary, patients treated with Rtx-Clb or with Ofa-Clb would receive on average a second line treatment consisting in the majority of cases of ibrutinib monotherapy, or rituximab with idelalisib or rituximab with bendamustine. The sequence using Obi-Clb regimen in first line showed the lower mean cost of treatment: €22,958 over the 48-month time horizon. Sensitivity analyses on a couple of scenarios provided similar conclusions in terms of overall costs.ConclusionObi-Clb as first-line treatment appears a recommendable strategy in terms of drug costs in the treatment of patients with previously untreated CLL and coexisting conditions.

    Highlights: • Heavy metals in spent compact fluorescent lamps (CFLs) determined. • Current waste management condition of CFLs in Iran assessed. • Currently, waste of CFLs is disposed by municipal waste stream in waste landfills. • We propose extended producer responsibility (EPR) for CFLs waste management. - Abstract: From environmental viewpoint, the most important advantage of compact fluorescent lamps (CFLs) is reduction of green house gas emissions. But their significant disadvantage is disposal of spent lamps because of containing a few milligrams of toxic metals, especially mercury and lead. For a successful implementation of any waste management plan, availability of sufficient and accurate information on quantities and compositions of the generated waste and current management conditions is a fundamental prerequisite. In this study, CFLs were selected among 20 different brands in Iran. Content of heavy metals including mercury, lead, nickel, arsenic and chromium was determined by inductive coupled plasma (ICP). Two cities, Tehran and Tabriz, were selected for assessing the current waste management condition of CFLs. The study found that waste generation amount of CFLs in the country was about 159.80, 183.82 and 153.75 million per year in 2010, 2011 and 2012, respectively. Waste generation rate of CFLs in Iran was determined to be 2.05 per person in 2012. The average amount of mercury, lead, nickel, arsenic and chromium was 0.417, 2.33, 0.064, 0.056 and 0.012 mg per lamp, respectively. Currently, waste of CFLs is disposed by municipal waste stream in waste landfills. For improving the current conditions, we propose by considering the successful experience of extended producer responsibility (EPR) in other electronic waste management. The EPR program with advanced recycling fee (ARF) is implemented for collecting and then recycling CFLs. For encouraging consumers to take the spent CFLs back at the end of the products’ useful life, a proportion of

The study found that waste generation amount of CFLs in the country was about 159.80, 183.82 and 153.75 million per year in 2010, 2011 and 2012, respectively. Waste generation rate of CFLs in Iran was determined to be 2.05 per person in 2012. The average amount of mercury, lead, nickel, arsenic and chromium was 0.417, 2.33, 0.064, 0.056 and 0.012 mg per lamp, respectively. Currently, waste of CFLs is disposed by municipal waste stream in waste landfills. For improving the current conditions, we propose by considering the successful experience of extended producer responsibility (EPR) in other electronic waste management. The EPR program with advanced recycling fee (ARF) is implemented for collecting and then recycling CFLs. For encouraging consumers to take the spent CFLs back at the end of the products’ useful life, a proportion of

    National Nuclearelectrica Society (SNN) owns and operates two CANDU-6 plants at Cernavoda in Romania. Two additional units are expected to be built on the site in the future. Low and intermediate level short-lived radioactive wastes from Cernavoda are planned to be disposed off in a near-surface repository to be built at Saligny. The principal waste streams are IX resins, filters, compactable wastes, non-compactables, organic liquids and oil-solid mixtures. Their volumetric generation rates per reactor unit are estimated to be: IX resins (6 m{sup 3}/y), filters (2 m{sup 3}/y), compactables (23 m{sup 3}/y) and non-compactables (15 m{sup 3}/y). A techno-economic assessment of the available options for a facility to treat and condition Cernavoda's wastes for disposal was carried out in 2009 based on projected waste volumes from all four units. A large number of processes were first screened to identify viable options. They were further considered to develop overall processing options for each waste stream. These were then consolidated to obtain options for the entire plant by minimizing the number of unit operations required to process the various waste streams. A total of 9 plant options were developed for which detailed costing was undertaken. Based on a techno-economic assessment, two top ranking plant options were identified. Several scenarios were considered for implementing these options. Amongst them, a contractor run operation of a facility located on the Cernavoda site was considered to be more cost effective than operating the facility using SNN personnel. (author)

    Injection current dependences of electroluminescence transition energy in blue InGaN/GaN multiple quantum wells light emitting diodes (LEDs) with different quantum barrier thicknesses under pulsed current conditions have been analyzed taking into account the related effects including deformation caused by lattice strain, quantum confined Stark effects due to polarization field partly screened by carriers, band gap renormalization, Stokes-like shift due to compositional fluctuations which are supposed to be random alloy fluctuations in the sub-nanometer scale, band filling effect (Burstein-Moss shift), and quantum levels in finite triangular wells. The bandgap renormalization and band filling effect occurring at high concentrations oppose one another, however, the renormalization effect dominates in the concentration range studied, since the band filling effect arising from the filling in the tail states in the valence band of quantum wells is much smaller than the case in the bulk materials. In order to correlate the carrier densities with current densities, the nonradiative recombination rates were deduced experimentally by curve-fitting to the external quantum efficiencies. The transition energies in LEDs both with 15 nm quantum barriers and 5 nm quantum barriers, calculated using full strengths of theoretical macroscopic polarization given by Barnardini and Fiorentini [Phys. Status Solidi B 216, 391 (1999)] are in excellent accordance with experimental results. The LED with 5 nm barriers has been shown to exhibit a higher transition energy and a smaller blue shift than those of LED with 15 nm barriers, which is mainly caused by the smaller internal polarization field in the quantum wells.

    The paper presented here addresses the impact of waste management system operating parameters on overall system economics. The conclusion reached by this study is that currently available technology and proposed operating conditions do not lead to optimum economics. The decision to utilize the current reference waste package and non-optimum operating conditions will cause added expenditures of 7 billion dollars over the next several decades. Further, this paper points out that optimum economics is not necessarily incompatible with improved system safety

    Poverty is pervasive in the Swat Valley, Pakistan. Most of the people survive by farming small landholdings. Many earn additional income by collecting and selling plant material for use in herbal medicine. This material is collected from wild populations but the people involved have little appreciation of the potential value of the plant material they collect and the long term impact their collecting has on local plant populations. In 2012, existing practices in collecting and trading high value minor crops from Swat District, Pakistan, were analyzed. The focus of the study was on the collection pattern of medicinal plants as an economic activity within Swat District and the likely destinations of these products in national or international markets. Local collectors/farmers and dealers were surveyed about their collection efforts, quantities collected, prices received, and resulting incomes. Herbal markets in major cities of Pakistan were surveyed for current market trends, domestic sources of supply, imports and exports of herbal material, price patterns, and market product-quality requirements. It was observed that wild collection is almost the only source of medicinal plant raw material in the country, with virtually no cultivation. Gathering is mostly done by women and children of nomadic Middle Hill tribes who earn supplementary income through this activity, with the plants then brought into the market by collectors who are usually local farmers. The individuals involved in gathering and collecting are largely untrained regarding the pre-harvest and post-harvest treatment of collected material. Most of the collected material is sold to local middlemen. After that, the trade pattern is complex and heterogeneous, involving many players. Pakistan exports of high value plants generate over US$10.5 million annually in 2012, with a substantial percentage of the supply coming from Swat District, but its market share has been declining. Reasons for the decline were

    From environmental viewpoint, the most important advantage of compact fluorescent lamps (CFLs) is reduction of green house gas emissions. But their significant disadvantage is disposal of spent lamps because of containing a few milligrams of toxic metals, especially mercury and lead. For a successful implementation of any waste management plan, availability of sufficient and accurate information on quantities and compositions of the generated waste and current management conditions is a fundamental prerequisite. In this study, CFLs were selected among 20 different brands in Iran. Content of heavy metals including mercury, lead, nickel, arsenic and chromium was determined by inductive coupled plasma (ICP). Two cities, Tehran and Tabriz, were selected for assessing the current waste management condition of CFLs. The study found that waste generation amount of CFLs in the country was about 159.80, 183.82 and 153.75 million per year in 2010, 2011 and 2012, respectively. Waste generation rate of CFLs in Iran was determined to be 2.05 per person in 2012. The average amount of mercury, lead, nickel, arsenic and chromium was 0.417, 2.33, 0.064, 0.056 and 0.012 mg per lamp, respectively. Currently, waste of CFLs is disposed by municipal waste stream in waste landfills. For improving the current conditions, we propose by considering the successful experience of extended producer responsibility (EPR) in other electronic waste management. The EPR program with advanced recycling fee (ARF) is implemented for collecting and then recycling CFLs. For encouraging consumers to take the spent CFLs back at the end of the products' useful life, a proportion of ARF (for example, 50%) can be refunded. On the other hand, the government and Environmental Protection Agency should support and encourage recycling companies of CFLs both technically and financially in the first place.

    Educational justice is a process by which all those involved in education are pondering and seeking to establish it in their regulatory environments. This study aimed to investigate effective factors in an ideal educational justice and the current condition of educational justice from the students' viewpoint and ultimately increase the awareness and understanding of authorities and educational planners of the existing shortcomings.  This is a descriptive-analytical study. Samples include all nursing, operating room, and anesthesia students of nursing and paramedical college who had passed at least 5 semesters. Data collection was carried out through a scholar questionnaire. Validity was assessed through content validity and reliability of the questionnaire was evaluated using a pilot study.  In order to determine the status of the scores, 5 points (very high), 4 (often), 3 (moderate), 2 (low) and 1 (very low) were assigned, respectively. To determine the justice level, a 35 score interval was considered as very low, low, medium, high and very high. SPSS software, descriptive statistics, independent t-test and ANOVA were used to analyze the data.  There was a significant difference between the ideal and the current conditions in all items (p≤0.001) and also in the total mean score of ideal condition  and mean score of current condition (p=0.010). In an educational system, educational methods and aims should be regulated in a way that principles and components of justice are attainable and distribution and allocation of educational facilities of justice are considered thoroughly.

    The decision to breed influences an individual's current and future reproduction, and the proportion of individuals that breed is an important determinant of population dynamics. Age, experience, individual quality, and environmental conditions have all been demonstrated to influence breeding propensity. To elucidate which of these factors exerts the greatest influence on breeding propensity in a temperate waterfowl, we studied female Lesser Scaup (Aythya affinis) breeding in southwestern Montana. Females were captured during the breeding seasons of 2007–2009, and breeding status was determined on the basis of (1) presence of an egg in the oviduct or (2) blood plasma vitellogenin (VTG) levels. Presence on the study site in the previous year, a proxy for adult female success, was determined with stable isotope signatures of a primary feather collected at capture. Overall, 57% of females had evidence of breeding at the time of capture; this increased to 86% for females captured on or after peak nest initiation. Capture date and size-adjusted body condition positively influenced breeding propensity, with a declining body-condition threshold through the breeding season. We did not detect an influence of age on breeding propensity. Drought conditions negatively affected breeding propensity, reducing the proportion of breeding females to 0.85 (SE = 0.05) from 0.94 (SE = 0.03) during normal-water years. A female that was present in the previous breeding season was 5% more likely to breed than a female that was not present then. The positive correlation between age and experience makes it difficult to differentiate the roles of age, experience, and individual quality in reproductive success in vertebrates. Our results indicate that individual quality, as expressed by previous success and current body condition, may be among the most important determinants of breeding propensity in female Lesser Scaup, providing further support for the individual heterogeneity hypothesis.

    With the fast urbanization process, how does the vegetation environment change in one of the most economically developed metropolis, Shanghai in East China? To answer this question, there is a pressing demand to explore the non-stationary relationship between socio-economic conditions and vegetation across Shanghai. In this study, environmental data on vegetation cover, the Normalized Difference Vegetation Index (NDVI) derived from MODIS imagery in 2003 were integrated with socio-economic data to reflect the city's vegetative conditions at the census block group level. To explore regional variations in the relationship of vegetation and socio-economic conditions, Ordinary Least Squares (OLS) and Geographically Weighted Regression (GWR) models were applied to characterize mean NDVI against three independent socio-economic variables, an urban land use ratio, Gross Domestic Product (GDP) and population density. The study results show that a considerable distinctive spatial variation exists in the relationship for each model. The GWR model has superior effects and higher precision than the OLS model at the census block group scale. So, it is more suitable to account for local effects and geographical variations. This study also indicates that unreasonable excessive urbanization, together with non-sustainable economic development, has a negative influence of vegetation vigor for some neighborhoods in Shanghai.
