Full Text Available The problems of wealth and economic performance are old but despite their importance we have not a final answer on them. Besides the standard production factors usually stresed when we analyze economic performance and growth, land, labor and capital, we approach institutions in general and entrepreneurial culture in particular. In this paper we analyze the relationship between entreprenurship, defined by many dimensions derived from the study „Entrepreneurship in the EU and beyond.” requested by European Comission to the Gallup Internaitional, and economic performance measured by GDP/capita. The results show that countries where there is a strong entrepreneurial culture that promote initiative, opportunity seeking, risk taking aare doing better in terms of development level and wealth. At the same time the countries where the entrepreneurs have a good image in society, and thus promote entrepreneurship, are doing beter than the other countries.

Academic performance is the mean objective of the teaching-learning process, but there are many other variables or factors outside the OB/GYN resident involved in this process, such as those related to the environment in which they operate, teachers, interaction with their peers, family, society, and many other factors contained individually, such as learning styles, motivation, study habits, personality traits, among others. Identify which are the main socio-economic and psycho-affective factors that influence on academic performance of residents in Obstetrics and Gynecology. Observational, cross-sectional quantitative, correlational and non-experimental study in Obstetrics and Gynecology residents of a public general hospital tertiary care. A type survey to obtain data and deepen personal and socioeconomic status of each resident instrument was designed. Females predominated with 15 cases and only 5 were male. Sixteen of medical residents claimed that having a good habit of sleep helps improve their academic performance and their performance in academic and healthcare activities. Fifteen felt that work much better with peers of the opposite sex. Ten felt that developing a type of self-directed learning contributes greatly to improve their performance and 19 felt that having a mentor during residency contributes to improve their academic performance. Fifteen reported being victim of abuse or discrimination from their peers. Sixteen claimed to have been very sad or depressed at some point during residency. Eight consumed alcohol and seven used tobacco to relax.

2013-12-01

Full Text Available Some factors that affect the economic life indirectly but substantially at the same time are assumed exogenous or fixed by the traditional economics. However, these factors are considered fixed are the factors that affect the economy deeply. Political stability, verdicts devoid of justice, military coups and interventions, oligarchical bureaucratic structure, and terrorism are important factors assumed to be fixed. Although these factors may seem irrelevant at first glance, they have crucial impacts on economies. Important determinants of Turkey’s economic performance have been political decisions, the verdicts devoid of justice, in other words biased verdicts, military coups and interventions, oligarchical bureaucratic structure, and terrorism rather than economic policies. In this study, it is discussed that the effects of military coups and interventions on the performance of the economy in the context of Turkey example; and the hypothesis is validated within the framework of an econometric model.

Full Text Available Each company is surrounded by the micro- and macro-environment affecting also its economic performance. These factors are not only individual accounting entries, but also analytical inputs as the internal company processes, management of costs or short-term financial decisions and specifically in the case of agriculture within the EU also the public subsidy schemes implemented through the EU Common Agricultural Policy. Groups of agricultural producers are created as a response to current market dynamics and the opportunity for each agricultural enterprise regardless the size. In this paper, the basis for agricultural cooperation is provided, traditional economic performance measures are presented and their applicability on the sample of agricultural producers’ groups and wholesale entities is empirically verified. Wholesale entities are analysed by its business activity and performance features to consider whether they are suitable peer group for comparing economic performance of examined agricultural producers’ group. Since the economic performance of agricultural producers’ groups directly affects the economic performance of all participating entities, and vice versa, their economic performance measurement may involve specific constraints. According to the structure and characteristics of agricultural producers’ groups may be inferred that whilst the common performance measurement techniques are applicable on the majority of companies, agricultural producers’ groups represent specific entities and therefore need adjusted performance measurement approach.

HOW TO SUSTAIN ECONOMIC PERFORMANCE? ECONOMIC GROWTH AND ITS IMPACT FACTORS

Directory of Open Access Journals (Sweden)

OANA SIMONA HUDEA (CARAMAN

2012-05-01

Full Text Available This paper intends to render several important factors of impact on economic growth and to describe the particular types of relationships of the latter with each one of its influencing elements. In order to correctly determine such issue, we have resorted to three carefully selected models that have been estimated and compared so as to identify the most adequate and representative regression. For this purpose we have performed an analysis based on cross-section annual data for 105 countries spread all over the world. After having tested and rejected certain exogenous variables initially considered, such as imports or exports, we have finally retained the external debt and foreign direct investments as explanatory items of the dependent variable. The results revealed that both of them positively affect the gross domestic product of the analysed countries, this one being inelastic in relation to the exogenous variables considered. Even if the relationship between the economic growth and the external debt of a country is usually negative, as the money exit out of the country due to the debt service causes non-achieved potential investments, yet, there is an inflexion point up to which the external debt has a positive influence on economic growth by the increase of the investments funds acquired as result of the external credit contracting, this being the case reflected by our study. As for the relationship existing between foreign direct investments and GDP, the economic theory confirms that FDI and economic growth are directly correlated, the former contributing to technical progress, production increase and, finally, to the improvement of the living standard.

Wicke, Birka; Smeets, Edward M W; Akanda, Razzaque; Stille, Leon; Singh, Ranjay K; Awan, Abdul Rasul; Mahmood, Khalid; Faaij, Andre P C

2013-09-30

This study explores the greenhouse gas balance and the economic performance (i.e. net present value (NPV) and production costs) of agroforestry and forestry systems on salt-affected soils (biosaline (agro)forestry) based on three case studies in South Asia. The economic impact of trading carbon credits generated by biosaline (agro)forestry is also assessed as a potential additional source of income. The greenhouse gas balance shows carbon sequestration over the plantation lifetime of 24 Mg CO2-eq. ha(-1) in a rice-Eucalyptus camaldulensis agroforestry system on moderately saline soils in coastal Bangladesh (case study 1), 6 Mg CO2-eq. ha(-1) in the rice-wheat- Eucalyptus tereticornis agroforestry system on sodic/saline-sodic soils in Haryana state, India (case study 2), and 96 Mg CO2-eq. ha(-1) in the compact tree (Acacia nilotica) plantation on saline-sodic soils in Punjab province of Pakistan. The NPV at a discount rate of 10% is 1.1 k€ ha(-1) for case study 1, 4.8 k€ ha(-1) for case study 2, and 2.8 k€ ha(-1) for case study 3. Carbon sequestration translates into economic values that increase the NPV by 1-12% in case study 1, 0.1-1% in case study 2, and 2-24% in case study 3 depending on the carbon credit price (1-15 € Mg(-1) CO2-eq.). The analysis of the three cases indicates that the economic performance strongly depends on the type and severity of salt-affectedness (which affect the type and setup of the agroforestry system, the tree species and the biomass yield), markets for wood products, possibility of trading carbon credits, and discount rate.

Economic performance of liquid-metal fast breeder reactor and gas-cooled fast reactor radial blankets

International Nuclear Information System (INIS)

Tsoulfanidis, N.; Jankhah, M.H.

1979-01-01

The economic performance of the radial blanket of a liquid-metal fast breeder reactor (LMFBR) and a gas-cooled fast reactor (GCFR) has been studied based on the calculation of the net financial gain as well as the value of the levelized fuel cost. The necessary reactor physics calculations have been performed using the code CITATION, and the economic analysis has been carried out with the code ECOBLAN, which has been written for that purpose. The residence time of fuel in the blanket is the main variable of the economic analysis. Other parameters that affect the results and that have been considered are the value of plutonium, the price of heat, the effective cost of money, and the holdup time of the spent fuel before reprocessing. The results show that the radial blanket of both reactors is a producer of net positive income for a broad range of values of the parameters mentioned above. The position of the fuel in the blanket and the fuel management scheme applied affect the monetary gain. There is no significant difference between the economic performance of the blanket of an LMFBR and a GCFR

Liu Yachun; Zou Shuliang

2012-01-01

The economical efficiency of nuclear power includes a series of environmental parameters, for example, cleanliness. Nuclear security is the precondition and guarantee for its economy, and both are the direct embodiment of the social benefits of nuclear power. Through analyzing the supervision and management system on the effective operation of nuclear power plants, which has been put forward by the International Atomic Energy Agency (IAEA), the World Association of Nuclear Operators (WANO), the U.S. Nuclear Regulatory Commission (NRC), and other organizations, a set of indexs on the safety performance and economical efficiency of nuclear power are explored and established; Based on data envelopment analysis, a DEA approach is employed to evaluate the efficiency of the operation performance of several nuclear power plants, Some primary conclusion are achieved on the basis of analyzing the threshold parameter's sensitivity and relativity which affected operational performance. To address the conflicts between certain security and economical indicators, a multi-objective programming model is established, where top priority is given to nuclear safety, and the investment behavior of nuclear power plant is thereby optimized.

2015-03-01

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

How does economic risk aversion affect biodiversity?

Science.gov (United States)

Mouysset, L; Doyen, L; Jiguet, F

2013-01-01

Significant decline of biodiversity in farmlands has been reported for several decades. To limit the negative impact of agriculture, many agro-environmental schemes have been implemented, but their effectiveness remains controversial. In this context, the study of economic drivers is helpful to understand the role played by farming on biodiversity. The present paper analyzes the impact of risk aversion on farmland biodiversity. Here "risk aversion" means a cautious behavior of farmers facing uncertainty. We develop a bio-economic model that articulates bird community dynamics and representative farmers selecting land uses within an uncertain macro-economic context. It is specialized and calibrated at a regional scale for France through national databases. The influence of risk aversion is assessed on ecological, agricultural, and economic outputs through projections at the 2050 horizon. A high enough risk aversion appears sufficient to both manage economic risk and promote ecological performance. This occurs through a diversification mechanism on regional land uses. However, economic calibration leads to a weak risk-aversion parameter, which is consistent with the current decline of farmland birds. Spatial disparities however suggest that public incentives could be necessary to reinforce the diversification and bio-economic effectiveness.

The odd couple: The relationship between state economic performance and carbon emissions economic intensity

International Nuclear Information System (INIS)

Davidsdottir, B.; Fisher, M.

2011-01-01

Historical time trends indicate that both carbon and energy intensity have declined in the United States over the last several decades, while economic performance, as measured by per capita GSP, has improved. This observation indicates that it may be possible to reduce carbon intensity without a reduction in economic performance. This paper assesses using panel analysis, the empirical relationship between carbon emissions intensity and economic performance, and examines the direction of causality between the two variables. Data for the analysis covered 48 states, excluding Hawaii, Alaska, and Washington DC, from 1980 to 2000. The results indicate significant bi-directional relationship between carbon emissions intensity and state economic performance, both using an aggregate indicator for carbon emissions intensity, decomposed using Laspeyres indexes and disaggregated by sector. This implies that it should be possible to implement statewide and sector-specific policies to reduce energy and carbon intensity and at the same time improve economic performance. - Highlights: → The empirical relationship between carbon emissions intensity and economic performance is assessed → The direction of causality between the two variables is examined. → Results indicate significant relationship between carbon emissions intensity and state economic performance. → Relationship is bi-directional, and holds for both aggregate analysis and by sector. → It is possible to implement policies to reduce carbon intensity and improve economic performance.

Full Text Available The role of fiscal policy in promoting economic growth has been subject to many studies since its suggestion by Keynes who stated expansionary/contractionary impact of public expenditures/taxes. In this context, effectiveness of fiscal policy use to develop non-oil sector in resource rich economies should be studied. This paper investigates short- and long-run effects of budget expenditures and tax related budget revenues (direct transfers from oil fund excluded over non-oil GDP while controlling for oil price volatility and oil production in case of Azerbaijan. Autoregressive Distributed Lag Bounds Testing (ARDLBT Approach to cointegration is employed for data covering 2000Q1-2015Q2. Estimation results theoretically consistent and statistically significant long-run effects of both budget expenditures and tax-related budget revenues. However, in the short-run, the effects are contrary to the theoretical expectations. Findings are useful for Azerbaijan fiscal policy makers especially in the current complicated nature of economic processes in the economy due to oil related challenges.

The Influence of Multiple Specializations on Economic Performance in U.S. Metropolitan Areas

Directory of Open Access Journals (Sweden)

Saheum Hong

2016-09-01

Full Text Available Scholars have recently been debating how economic structure affects regional economic performance. Regional economic structure typically indicates how the industries in regions are organized. The attribute of industrial organization in regions is typically measured by how the employment in a region is distributed among various sectors. If the employment in a region is highly concentrated on a limited number of sectors, that region is industrially specialized. On the contrary, when the employment is more evenly distributed among various industries, that region is highly diversified in its industrial organization. In this context, some researchers recognized that diversity and specialization are not opposite concepts. Instead, they can coexist, for example in the form of diversified specializations. In this study, this body of literature was extended by formulating an indicator to measure the extent of multiple specializations in regional economies and by examining the effect of multiple specializations on regional economic performance. Empirical analysis showed that specializing in multiple industrial pursuits helped regions to achieve both faster and more stable economic growth.

2015-04-01

This article focuses on employee performance-management practices in the healthcare sector. We specifically aim to contribute to a better understanding of the impact of employee performance-management practices on affective well-being of nurses in hospitals. Theory suggests that the features of employee-performance management (planning and evaluation of individual performances) predict affective well-being (in this study: job satisfaction and affective commitment). Performance-management planning and evaluation and affective well-being were drawn from a survey of nurses at a Flemish hospital. Separate estimations were performed for different aspects of affective well-being. Performance planning has a negative effect on job satisfaction of nurses. Both vertical alignment and satisfaction with the employee performance-management system increase the affective well-being of nurses; however, the impact of vertical alignment differs for different aspects of affective well-being (i.e. job satisfaction and affective commitment). Performance-management planning and evaluation of nurses are associated with attitudinal outcomes. The results indicate that employee performance-management features have different impacts on different aspects of well-being. Copyright © 2014 Elsevier Ltd. All rights reserved.

The uses of lighter-than-air vehicles are examined in the present day transportation environment. Conventional dirigibles were found to indicate an undesirable economic risk due to their low speeds and to uncertainties concerning their operational use. Semi-buoyant hybrid vehicles are suggested as an alternative which does not have many of the inferior characteristics of conventional dirigibles. Economic and performance estimates for hybrid vehicles indicate that they are competitive with other transportation systems in many applications, and unique in their ability to perform some highly desirable emergency missions.

Causal Dynamic Relationships between Political–Economic Factors and Export Performance in the Renewable Energy Technologies Market

Directory of Open Access Journals (Sweden)

Bongsuk Sung

2018-04-01

Full Text Available This study explores how political–economic forces could affect export performance in the renewable energy technologies market. We conduct panel framework analyses to verify the characteristics of panel data for 19 countries before establishing the panel estimator meant to test the effects of political–economic forces on export specialization. We consider the results of the panel framework analyses and develop an empirical model to test casual dynamic relationships between political–economic forces and export performance. The results from the least squares dummy variable-corrected estimation indicate that the major factors promoting the export specialization of renewable energy technologies are, in order of decreasing importance, public pressure, market size, and government demand-pull policy. However, the traditional energy industry has no significant effect on export performance. Finally, this study finds that dynamic effects exist in all estimations.

Economic structure and performance of forest-based industries

International Nuclear Information System (INIS)

O'Laughlin, J.

1989-01-01

This paper reports on the economic structure, conduct, and performance of industries dependent on the nation's forests that are topics of special importance for research. A major challenge to research involving industrial organization of forest-based industries is to link descriptions of structure, conduct, and industrial performance in ways that facilitate public and private policy making. Not to be overlooked is the need to continue efforts to monitor changes in structure and conduct dimensions at the national level and to conduct baseline studies of industry structure-conduct-performance at regional, state, and local levels. Specifically needed is research that will improve understanding of restructuring within the wood-based industry; definitions of the wood-based industry and segments thereof; linkages between structure and regional economic development; timberland as a managerial and economic variable; structural consequences of technological innovations; corporate strategies as related to performance; structural dimensions in an international setting; and structure and performance of nonwood-based forest industries. Economics research focused in such directions will go far toward improving the manner in which the nation's many forest industries organize and conduct their activities

Full Text Available Today the economic performance of enterprises is defined in a different way compared to traditional approaches, to understand the modern definitions will need to review the evolution of the concept from the beginnings until nowadays. In the traditional approach the economic performance of the enterprises was defined only by the perspective shareholders’, so the business owners, what is not surprising, as it was considered the source of rewarding investors and the main purpose of the business. Today a company is performing if he responds and at the economic level to the expectations of several stakeholder groups. In this article we review the evolution of these notions and we give a definition based on the modern approaches taking into account and the fact that, we can't discuss economic performance without social performance and environmental performance of an enterprise. In the last resort we aproach system measurement of the performance that meets the expectations generated by today's society.

How Does Social Trust Affect Economic Growth?

Bjørnskov, Christian

Social capital in the form of generalized trust has been shown to be a determinant of economic growth in a number of studies. Other studies have explored other consequences of trust, such as its effects on governance, corruption, education and investment. This paper connects the two strands...... of literature by estimating the effects of trust on growth through a set of potential transmission mechanisms directly. It does so by modelling the process using a three-stage least squares estimator on a sample of countries for which a full data set is available. The results indicate that trust affects...

Full Text Available There is a lack of empirical data segregation on factors affecting gender as the variable of interest. However, previous research had indicated several factors that affect business performances among small-scale enterprise owners. Using feminist theory and a descriptive survey research design, data were collected from fifty (50 small-scale enterprise owners that were purposively chosen across the study area. The findings show that the factors that were significant for female were significantly different from male. For female small scale enterprise owners, marital status (64% Age of Children (68%, Role Model/ advisors (58% were significant factors that affect their business performance. For male small-scale enterprise owners, Friends (70%, a lack of Government support (80%, inability to display innovativeness (78% and Risk-Taking (84% were significant for male. Lack of availability of capital and finances were significant for the two. Other factors that affect performance include friends, inadequate training and business location. Adequate knowledge of factors that affect gender enterprise performance will go a long way in alleviating these problems. Small-scale enterprises should be supported for poverty alleviation, especially among women and for the nation’s economic development

ECONOMIC CRISIS AND ECONOMIC DISPARITIES IN EUROPEAN UNION

Directory of Open Access Journals (Sweden)

Rodica CRUDU

2015-09-01

Full Text Available The impact of the economic and financial crisis is still being felt. It started as an acute crisis of the banking system, but then quickly affected the real economy, causing a substantial slump in business investment, household demand and output. The current economic crisis has affected almost all European countries but the countries of the European south and the former eastern socialist republics have suffered the most. The objective in this paper is to quantify economic disparities as expressed by several growth indicators, such as GDP per capita, employment/unemployment rates, labour productivity rates and use them to compare the economic performances before and after the crisis. EU took several measures to recover from the economic crisis. Nevertheless, its ability to adjust to widely diverse national and local contexts that have been impacted differently by the effects of the crisis, and to support the different patterns of economic growth that will result from it, is yet to be seen.

Psychological factors affecting equine performance

McBride Sebastian D

2012-09-01

Full Text Available Abstract For optimal individual performance within any equestrian discipline horses must be in peak physical condition and have the correct psychological state. This review discusses the psychological factors that affect the performance of the horse and, in turn, identifies areas within the competition horse industry where current behavioral research and established behavioral modification techniques could be applied to further enhance the performance of animals. In particular, the role of affective processes underpinning temperament, mood and emotional reaction in determining discipline-specific performance is discussed. A comparison is then made between the training and the competition environment and the review completes with a discussion on how behavioral modification techniques and general husbandry can be used advantageously from a performance perspective.

Full Text Available This study ascertained the relationship between difficulties and coping strategies as related to teaching performance of West Visayas State University-Janiuay Campus (WVSU-JC faculty for the School Year 2014-2015. The survey-correlational method was used with teaching performance as dependent variables, experienced economic difficulties as the independent variable, and coping strategy as moderator variable. The participants in the study were the 52 faculty who were selected through purposive sampling. Data were gathered through a researcher-made questionnaire-checklist and Faculty Performance Evaluation System. The statistical tools used were frequency count, rank, mean, standard deviation, and Pearson's Product-Moment Coefficient of Correlation. All statistical computations were availed of through the Statistical Package for the Social Sciences (SPSS software. Results revealed that the top economic difficulty experienced by faculty was limited cash. The topmost coping strategy employed by faculty was buying only basic foods or things for household. The faculty also experienced economic difficulty to a “moderate extent.” Nevertheless, the performance of the faculty was found to be “outstanding.” Teachers were affected by such financial crisis. However, despite their experienced economic difficulties, as major agents for change, they performed their best for the improvement of quality education. No significant relationships existed between coping strategies and teaching performance of faculty.

EXCHANGE RATE DIFFERENCES-THE ACCOUNTING TREATMENT AND ITS INFLUENCE ON THE FINANCIAL PERFORMANCE OF AN ECONOMIC ENTITY

Directory of Open Access Journals (Sweden)

Nicoleta Cristina MATEI

2016-06-01

Full Text Available Currency rate differences arise when there are certain debt rights or obligations in foreign currency of an economic entity which are collected, i.e. paid for at a different course from the one displayed by the Romanian National Bank on the date of their establishment. Such differences, according to the situation, generate expenditure or revenue which affects a company's financial result and, consequently, the accountant result as well. The results registered by an economic entity presented in the Profit and Loss Account provide information about its financial performance. This performance can be influenced by the favorable or unfavorable exchange rate differences existing when an economic entity carries out transactions or has incurred foreign currency loans having a significant share in the total amount of transactions or in capitals. The present paper shows the accounting treatment of the exchange rate differences and its impact on the financial performance.

Considerazioni sullo sviluppo economico del Giappone. (Japanese economic performance

A. MADDISON

2014-07-01

Full Text Available Japan is the only non-European country to have made the transition from being underdeveloped. Over the past century it has had the fastest growth rate of any country, and in the past decade has outpaced all other countries. More than in any other developed country except the U.S.S.R., Japanese growth has represented a deliberate effort of government policy. The Japanese experience is therefore of particular relevance to developing countries, and its recent performance also raises important queries for Europe. The present article analyses Japan’s economic performance considering whether ideas on feasible growth rates need be revised, to what extent Japan has succeeded in achieving maximum growth, and if its experience is transferable. The author first details the stages of Japan’s growth, before analysing the level of productivity and use of resources. The business cycle is then considered as well as the factors affecting growth performance. The author then examines the lessons of the Japanese experience for developing countries and finally the prospects for the future.JEL: O53

Apolzan Carmen Maria

2012-07-01

Full Text Available In this paper we examine the performance of investment funds during the period 2006-2010, intending to comprise the portfolio performance’s dynamics before, during and after the present economic and financial crises climax. We categorize investment funds according to their investment strategy and geographical focus and distinguish a number of 11 classes. In order to analyze their returns’ dynamics, we create a fund performance index for each category using principal components method. The instability created in financial system in 2007 had a direct impact on institutional investors’ portfolios regardless of investment strategy, effects that have rapidly propagated on real economy. Analyzing index’s dynamics correlated with economic growth we conclude that financial and economic environment react in the same direction, but with a certain time delay, to instability factors. We also underline the major impact of boom and bust evolution of financial markets on real economy, cause of the current economic and financial crises.

Lavinia Mihaela GUŢU

2015-04-01

Full Text Available Banks are important cells in the economy as they have a significant role by maintaining and encouraging the development of economic sectors. They refocus the resources from those who have surplus to those which have a deficit. Therefore, as any other enterprises, performance is highly desirable for banks and, then, it is crucial to discover what the main factors that influence this objective are. So, this paper analyzes the microeconomic factors affecting bank’s financial performance focusing on 11 entities for the period between 2003 and 2013. The performance is measured by return on assets. The independent variables used are bank’s size, financial leverage,loans to assets ratio, deposits to assets ratio, number of employees, liquidity, net result and monetary policy rate. The results show that bank’s size, loans to assets ratio and liquidity have not a significant impact on performance. Financial leverage has a negative impact, meanwhile the number of employees, deposits to assets ratio and net result have a positive effect.

Bokkers, E A M; de Boer, I J M

2009-09-01

1. In this study, we compared a conventional broiler production system keeping fast growing broilers with an organic broiler production system keeping slow growing broilers in the Netherlands, both managed by one person working a full time year (Full Time Equivalent, FTE). This comparison was based on a quantification of economic, ecological and social indicators. Indicators were quantified using scientific literature and national data sets. 2. The organic system performed better for the economic indicator net farm income per FTE than the conventional system. 3. Regarding ecological indicators, calculations showed a higher on-farm emission of ammonia per kg live weight for the organic system. Moreover, an organic system includes a higher risk for eutrophication per ha due to outdoor access. Emission of green house gasses, use of fossil fuels and use of land required for the production of one kg of live weight is higher for an organic than for a conventional system. This is mainly due to a lower feed conversion in organic production and use of organic feed. 4. The organic system performed better than the conventional system for the social indicators related to animal welfare time spent on walking, footpad lesions, mortality, and sound legs. Regarding the social indicator food safety was found that meat from an organic system contained less antibiotic residues and Salmonella contaminations but more Campylobacter contaminations than meat from a conventional system. 5. Changing from a conventional to an organic broiler production system, therefore, not only affects animal welfare, but also affects economic, ecological and other social issues. In this study, we ran into the situation that some information needed was lacking in literature and quantifications had to be based upon several sources. Therefore, an integrated on-farm assessment is needed, which can be used to develop a broiler production system that is economically profitable, ecologically sound, and

The economic and financial performance of Bahrain's Fisheries Sector

International Nuclear Information System (INIS)

Abdulqader, E.A.A.

2007-01-01

This work is based on an extensive socio-economic survey conducted at all Bahrain landing sites in the period July-November, 2002. Based on boat size and the type of fishing gear used, eight fisheries sectors were determined, these included small boats using wire traps, shrimp trawls, gillnets, hooks and lines and barrier traps. It also included large boats using wire traps, shrimp trawls and gillnets. The economic and financial performances of these sectors were evaluated. The ratio of net catch flow to total earnings was used to measure the economic performance, while the return over investment was used to measure the financial performance. Higher economic returns (except for gillnet and shrimp trawl fisheries) were found in the case of small boats where smaller investments are found. This indicated that an over-fishing condition exists in Bahrain's fisheries, which is clearly found in the case of the shrimp trawl fishery. (author)

Full Text Available The Economic Value Added (EVA is an index of “durable development.” It was proposed by the Stern-Stewart Office and represents the true economic profit of companies. A company reports economic profit only if thereported accounting profit is higher than the opportunity cost of equity. The authors of the EVA model (Stern-Stewart have also proposed the ways of restating the financial statements to get a “fair image” of the results, thuseliminating the “accounting distortions.”Based on the performance indexes calculated based on EVA and second-generation indexes relating toEVA, we calculated two types of rating: Rating Performance Current and Rating Performance Trend. The rating iscalculated by means of the percentiles technique and the results are split into 22 rating classes.The used database is Russell 3000.

The End TB Strategy mandates that no tuberculosis (TB)-affected households face catastrophic costs due to TB. However, evidence is limited to evaluate socioeconomic support to achieve this change in policy and practice. The objective of the present study was to investigate the economic effects of a TB-specific socioeconomic intervention. The setting was 32 shantytown communities in Peru. The participants were from households of consecutive TB patients throughout TB treatment administered by the national TB programme. The intervention consisted of social support through household visits and community meetings, and economic support through cash transfers conditional upon TB screening in household contacts, adhering to TB treatment/chemoprophylaxis and engaging with social support. Data were collected to assess TB-affected household costs. Patient interviews were conducted at treatment initiation and then monthly for 6 months. From February 2014 to June 2015, 312 households were recruited, of which 135 were randomised to receive the intervention. Cash transfer total value averaged US$173 (3.5% of TB-affected households' average annual income) and mitigated 20% of households' TB-related costs. Households randomised to receive the intervention were less likely to incur catastrophic costs (30% (95% CI 22–38%) versus 42% (95% CI 34–51%)). The mitigation impact was higher among poorer households. The TB-specific socioeconomic intervention reduced catastrophic costs and was accessible to poorer households. Socioeconomic support and mitigating catastrophic costs are integral to the End TB strategy, and our findings inform implementation of these new policies. PMID:27660507

Affective Management and its Effects on Management Performance

Waratta Authayarat

2012-01-01

Full Text Available Affective management is a new concept which suggests that top managers should take stakeholders’ affective experiences into account when making their management decisions. To show that this concept could contribute to the improvement of management performance in organizations, this study investigated the correlations between the affectiveness of top management and management performance indices. Our questionnaire based on the Affective Management Scorecard was employed to assess top managers’ recognition of the importance, as well as the actual practices of affective management. Top managers from 43 Thai organizations participated in the study. A correlation analysis was conducted to observe whether affective management indices would correlate with management performance indices, such as return on equity, return on assets, price to earnings ratio, and price to book value ratio. The findings showed that the results for organizations practicing affective management were positively correlated with their management performance in both profitability and good perceptions by investors.

2012-12-01

Individual affect-related performance zones (IAPZs) method utilizing Kamata et al. (J Sport Exerc Psychol 24:189-208, 2002) probabilistic model of determining the individual zone of optimal functioning was utilized as idiosyncratic affective patterns during golf performance. To do so, three male golfers of a varsity golf team were observed during three rounds of golf competition. The investigation implemented a multi-modal assessment approach in which the probabilistic relationship between affective states and both, performance process and performance outcome, measures were determined. More specifically, introspective (i.e., verbal reports) and objective (heart rate and respiration rate) measures of arousal were incorporated to examine the relationships between arousal states and both, process components (i.e., routine consistency, timing), and outcome scores related to golf performance. Results revealed distinguishable and idiosyncratic IAPZs associated with physiological and introspective measures for each golfer. The associations between the IAPZs and decision-making or swing/stroke execution were strong and unique for each golfer. Results are elaborated using cognitive and affect-related concepts, and applications for practitioners are provided.

Linares, J. L.; Herranz, L. E.; Moratilla, B. Y.; Fernandez-Perez, A.

2008-01-01

High temperature reached in High and Very High Temperature Reactors (VHTRs) results in thermal efficiencies substantially higher than those of actual nuclear power plants. A number of studies mainly driven by achieving optimum thermal performance have explored several layout. However, economic assessments of cycle power configurations for innovative systems, although necessarily uncertain at this time, may bring valuable information in relative terms concerning power cycle optimization. This paper investigates the thermal and economic performance direct Brayton cycles. Based on the available parameters and settings of different designs of HTGR power plants (GTHTR-300 and PBMR) and using the first and second laws of thermodynamics, the effects of compressor inter-cooling and of the compressor-turbine arrangement (i.e., single vs. multiple axes) on thermal efficiency have been estimated. The economic analysis has been based on the El-Sayed methodology and on the indirect derivation of the reactor capital investment. The results of the study suggest that a 1-axis inter-cooled power cycle has a similar thermal performance to the 3-axes one (around 50%) and, what's more, it is substantially less taxed. A sensitivity study allowed assessing the potential impact of optimizing several variables on cycle performance. Further than that, the cycle components costs have been estimated and compared.

Josefina Fernández-Guadaño

2015-12-01

Full Text Available The aim of this research is to use different economic variables to establish whether there are differences in economic performance between companies as a result of their inclusion in the sustainability index. This paper presents a one-dimensional exploratory study which compares the socially responsible companies included in the Spanish sustainability index, FTSE4Good Ibex, with the rest of the indices in the IBEX family. Parametric testing was used to study whether there are differences between the two types of companies. The results demonstrate that there are no statistically significant differences in economic performance between the two groups. Morover, it is confirmed that companies with good practices are as profitable as the rest, but it also demonstrates that the economic-financial behaviour is not better as a result of being in the sustainability index. The basic conclusion is that adhering to social and environmental standards does not harm a firm’s competitive position and, therefore, provide support for the development policy of responsible practices so that they become a tool to help improve the resilience of the economy and investor trust.

Full Text Available A system for measuring the economic and financial performance plays an important role in managing a business, because it provides the information necessary for decision making and launching of various actions. Tools and indicators for measurement and evaluation of economic and financial performance measures not only economic and financial performance, they are often integrated with policy, strategy, and many other aspects of behavior. Nowadays, complexity management forces managers to look at economic entities financial and economic performance under different angles either profitability or productivity, especially by creating value for shareholders and interest groups. As witch from one measurement system focused on financial parameters to another is only one aspect of change, have also gone to a new management style, participatory performance. The purpose of performance measurement company is multiple: to identify results that success or failure, to identify whether customer needs are met, to help the entity to understand its processes and to confirm what is known or to reveal what is not known, to identify where there are problems and where improvements are needed.

Full Text Available Africa belongs to important regions of the world economy with specific problems distinguishing this part of the world from other regions. The region is suffering because of limited economy structure and high level of poverty. Low economic performance ranks most of African countries among the worldwide poorest ones (both from the point of view of total economy performance and also individuals living standards; the development is hindered by political instability and also by other accompanied problems as high level of corruption, deficit of democracy, low level of education, limited investments, criminality, local conflicts, civil wars etc. On the other hand, African natural, economy and social resources and unexploited opportunities in many areas offer a potential for a considerable economic development. Understanding the current economic position of African states thus may reveal causes of problematic development and outline ways to overcome existing shortcomings. The aim of the paper is to analyze main changes in area of GDP structure formation (agricultural, industrial and services sector share in GDP and value performance which have occurred in selected African (Sub-Saharan countries. Changes are analyzed both in relation to the total GDP and GDP per capita. The authors identify main trends of economic development in the Sub-Saharan region and to specify differences among Sub-Saharan countries with the intention to identify particular groups of African countries according to their economic structure and to identify differences in their GDP formation.

per hectare or per cow reduced the CF of milk and increased farm profit. However, where higher milk production per hectare was associated with greater concentrate feeding, this adversely affected the CF of milk and economic performance by increasing both costs and off-farm emissions. Therefore, to mitigate the CF of milk and improve economic performance, grass-based dairy farms should not aim to only increase milk output, but instead target increasing milk production per hectare from grazed grass.

Highlights: • A double-step optimization tool for hybrid power generation systems is introduced. • Economical aspects and the impact of the system on the environment are considered. • A hybrid system comprises PV array-wind turbine-battery-diesel engine is considered. • Real time analysis of the system for full year simulation is carried out. • System optimum configuration at point where total performance index is maximized. - Abstract: This article aims to introduce a double-step performance assessment tool for the hybrid power generation systems. As a case study, a hybrid system comprising PV array, wind-turbine, battery bank and diesel engine is incorporated in hourly based simulations to meet power demand of a residence unit at Dhahran area, Kingdom of Saudi Arabia. Different indicators related to economical and environmental performance assessments of the hybrid system have been considered. In the economic related assessment case, cost of electricity, energy excess percentage, and operating life cycle indicators have been considered and combined to develop the first overall performance index. Renewable contribution, renewable source availability and environmental impact indicators have been considered for the environmental assessment case and they are combined in the second performance index. For either economical or environmental cases, the optimum configuration of the system is achieved by maximizing the first and second overall performance indicators. This innovative optimization tools gives the designer the freedom to assign suitable weights associated with economical aspect, environmental impact, governmental regulations and social impact, for the first and second overall performance indicators, and combine them in the total performance index. The optimum system configuration is at the point where the total performance index is maximized.

1. By monitoring the major social, economic, and political forces affecting health care, one can predict how these forces may impact the role of occupational health nurses. 2. Nursing can and must chart its own course in the midst of these social, economic, and political changes. 3. Changes which have major implications for occupational health nurses are: health care needs, cost containment, multi-hospital chains, alternative approaches to health care, the workplace, ethical concerns, biomedical technology, nursing shortage, and oversupply of physicians. 4. Nursing implications can also be drawn in the areas of autonomy, political skills, and education. Active involvement and a desire to shape professional change and the future of nursing are keys.

Highlights: • The optimal economic performance of the TRC system are investigated. • In economic evaluations, R125 performs the most satisfactorily, followed by R41 and CO 2 . • The TRC system with CO 2 has the largest averaged temperature difference. • Economic optimized pressures are always lower than thermodynamic optimized operating pressures. - Abstract: The aim of this study is to investigate the economic optimization of a TRC system for the application of geothermal energy. An economic parameter of net power output index, which is the ratio of net power output to the total cost, is applied to optimize the TRC system using CO 2 , R41 and R125 as working fluids. The maximum net power output index and the corresponding optimal operating pressures are obtained and evaluated for the TRC system. Furthermore, the analyses of the corresponding averaged temperature differences in the heat exchangers on the optimal economic performances of the TRC system are carried out. The effects of geothermal temperatures on the thermodynamic and economic optimizations are also revealed. In both optimal economic and thermodynamic evaluations, R125 performs the most satisfactorily, followed by R41 and CO 2 in the TRC system. In addition, the TRC system operated with CO 2 has the largest averaged temperature difference in the heat exchangers and thus has potential in future application for lower-temperature heat resources. The highest working pressures obtained from economic optimization are always lower than those from thermodynamic optimization for CO 2 , R41, and R125 in the TRC system

An economic analysis on oil or gas property is generally accompanied by a reservoir analysis which predicts the reserves and the performance of the reservoir, recommends the optimum economic method with which to recover the reserves, and through a performance prediction indicates a time schedule for future investments and income. The requirements for a reservoir evaluation are as follows: (1) good reservoir data; (2) oil in place; (3) reservoir energy, both primary and secondary; and (4) reserve calculation and performance predictions for giving both production schedule and selection of secondary recovery mechanisms. Given the above reservoir evaluation parameters, the following are requirements for a complete economic analysis: (1) lease exploration and purchase costs; (2) capital investments schedule dependent upon a reservoir performance prediction; and (3) factors affecting net income such as anticipated selling price of oil and gas and the availability of a market, operating costs and working interest, royalty schedule, depreciation methods, depletion methods and tax schedule.

2016-01-01

Full Text Available One of the determinants of the well-being of people across the world is economic freedom. It is the freedom to choose the ways to produce, sell, and use your private resources, while respecting rights of the other to practice the same. The primordial intention of the study was to investigate the factors affecting economic freedom in the Association of Southeast Asian Nations (ASEAN Economic Community. Human Development Index (HDI, Corruption Perceptions Index (CPI and GDP per capita are dimensions considered to characterize the level of a country’s economic freedom. Trend performance of AEC in these indexes was also determined. The empirical estimate was based on a panel dataset covering 6 member-countries of the ASEAN Economic Community from 2001 to 2010. The model was estimated through Ordinary Least Squares (OLS multiple linear regression analysis. For the trend performance of the indexes, Singapore found to have a remarkable performance. The empirical result strongly suggests that CPI and GDP per capita foster economic freedom. For every 1% decrease in CPI would lead to an increase in economic freedom index by.121 % and for every 1% increase in GDP per capita, EFI will increase by .019%.

Family economic strengthening and mental health functioning of caregivers for AIDS-affected children in rural Uganda

Science.gov (United States)

Wang, Julia Shu-Huah; Ssewamala, Fred M.; Han, Chang-Keun

2015-01-01

In sub-Saharan Africa, many extended families assume the role of caregivers for children orphaned by AIDS (AIDS-affected children). The economic and psychological stress ensued from caregiving duties often predispose caregivers to poor mental health outcomes. Yet, very few studies exist on effective interventions to support these caregivers. Using data from a randomized controlled trial called Suubi-Maka (N = 346), this paper examines whether a family economic strengthening intervention among families caring for AIDS-affected children (ages 12–14) in Uganda would improve the primary caregivers’ mental health functioning. The Suubi-Maka study comprised of a control condition (n = 167) receiving usual care for AIDS-affected children, and a treatment condition (n = 179) receiving a family economic strengthening intervention, including matched savings accounts, and financial planning and management training to incentivize families to save money for education and/or family-level income generating projects. This paper uses data from baseline/pre-intervention (wave 1) interviews with caregivers and 12-month post-intervention initiation (wave 2). The caregiver’s mental health measure adapted from previous studies in sub- Saharan Africa had an internal consistency of .88 at wave 1 and .90 at wave 2. At baseline, the two study groups did not significantly differ on caregiver’s mental health functioning. However, at 12-month follow-up, multiple regression analysis located significant differences between the two study groups on mental health functioning. Specifically, following the intervention, caregivers in the treatment condition reported positive improvements on their mental health functioning, especially in the symptom areas of obsession–compulsion, interpersonal sensitivity, hostility, and psychoticism. Findings point to a need for programs and policies aimed at supporting caregivers of AIDS-affected children to begin to consider incorporating family

How psychological framing affects economic market prices in the lab and field.

A fundamental debate in social sciences concerns how individual judgments and choices, resulting from psychological mechanisms, are manifested in collective economic behavior. Economists emphasize the capacity of markets to aggregate information distributed among traders into rational equilibrium prices. However, psychologists have identified pervasive and systematic biases in individual judgment that they generally assume will affect collective behavior. In particular, recent studies have found that judged likelihoods of possible events vary systematically with the way the entire event space is partitioned, with probabilities of each of N partitioned events biased toward 1/N. Thus, combining events into a common partition lowers perceived probability, and unpacking events into separate partitions increases their perceived probability. We look for evidence of such bias in various prediction markets, in which prices can be interpreted as probabilities of upcoming events. In two highly controlled experimental studies, we find clear evidence of partition dependence in a 2-h laboratory experiment and a field experiment on National Basketball Association (NBA) and Federation Internationale de Football Association (FIFA World Cup) sports events spanning several weeks. We also find evidence consistent with partition dependence in nonexperimental field data from prediction markets for economic derivatives (guessing the values of important macroeconomic statistics) and horse races. Results in any one of the studies might be explained by a specialized alternative theory, but no alternative theories can explain the results of all four studies. We conclude that psychological biases in individual judgment can affect market prices, and understanding those effects requires combining a variety of methods from psychology and economics.

Boere, Julia J; Fellinger, Lizz; Huizinga, Duncan J H; Wong, Sebastiaan F; Bijleveld, Erik

2016-02-01

A prevalent combination in daily life, performance pressure and caffeine intake have both been shown to impact people's cognitive performance. Here, we examined the possibility that pressure and caffeine affect cognitive performance via a shared pathway. In an experiment, participants performed a modular arithmetic task. Performance pressure and caffeine intake were orthogonally manipulated. Findings indicated that pressure and caffeine both negatively impacted performance. However, (a) pressure vs. caffeine affected performance on different trial types, and (b) there was no hint of an interactive effect. So, though the evidence is indirect, findings suggest that pressure and caffeine shape performance via distinct mechanisms, rather than a shared one. Copyright © 2015 Elsevier Inc.

Economic Drought Impact on Agriculture: analysis of all agricultural sectors affected

Gil, M.; Garrido, A.; Hernández-Mora, N.

2012-04-01

The analysis of drought impacts is essential to define efficient and sustainable management and mitigation. In this paper we present a detailed analysis of the impacts of the 2004-2008 drought in the agricultural sector in the Ebro river basin (Spain). An econometric model is applied in order to determine the magnitude of the economic loss attributable to water scarcity. Both the direct impacts of drought on agricultural productivity and the indirect impacts of drought on agricultural employment and agroindustry in the Ebro basin are evaluated. The econometric model measures losses in the economic value of irrigated and rainfed agricultural production, of agricultural employment and of Gross Value Added both from the agricultural sector and the agro-industrial sector. The explanatory variables include an index of water availability (reservoir storage levels for irrigated agriculture and accumulated rainfall for rainfed agriculture), a price index representative of the mix of crops grown in each region, and a time variable. The model allows for differentiating the impacts due to water scarcity from other sources of economic losses. Results show how the impacts diminish as we approach the macro-economic indicators from those directly dependent on water abstractions and precipitation. Sectors directly dependent on water are the most affected with identifiable economic losses resulting from the lack of water. From the management perspective implications of these findings are key to develop mitigation measures to reduce drought risk exposure. These results suggest that more open agricultural markets, and wider and more flexible procurement strategies of the agro-industry reduces the socio-economic exposure to drought cycles. This paper presents the results of research conducted under PREEMPT project (Policy relevant assessment of the socioeconomic effects of droughts and floods, ECHO - grant agreement # 070401/2010/579119/SUB/C4), which constitutes an effort to provide

Magdalene H. Awases

2013-04-01

Objectives: The aim of the present study was to identify factors affecting the performance of professional nurses in Namibia. Method: A quantitative, descriptive survey was used to collect data by means of a questionnaire. A random sample of 180 professional nurses was selected from six hospitals in three regions of Namibia. Results: Factors affecting the performance of nurses negatively were identified such as: lack of recognition of employees who are performing well, quality performance outcomes and an absence of a formal performance appraisal system and poor working conditions. Various factors contribute to both the positive and negative performance of professional nurses in Namibia. Strategies were developed for addressing the negative factors that could positively affect the performance of professional nurses in Namibia. Conclusions: This study emphasises the importance of developing strategies to promote the performance of nurses; build knowledge and expertise; develop mechanisms for improving the performance of nurses; expand leadership and management capacity; and generate information and knowledge through research.

Take a stand on your decisions, or take a sit: posture does not affect risk preferences in an economic task.

O'Brien, Megan K; Ahmed, Alaa A

2014-01-01

Physiological and emotional states can affect our decision-making processes, even when these states are seemingly insignificant to the decision at hand. We examined whether posture and postural threat affect decisions in a non-related economic domain. Healthy young adults made a series of choices between economic lotteries in various conditions, including changes in body posture (sitting vs. standing) and changes in elevation (ground level vs. atop a 0.8-meter-high platform). We compared three metrics between conditions to assess changes in risk-sensitivity: frequency of risky choices, and parameter fits of both utility and probability weighting parameters using cumulative prospect theory. We also measured skin conductance level to evaluate physiological response to the postural threat. Our results demonstrate that body posture does not significantly affect decision making. Secondly, despite increased skin conductance level, economic risk-sensitivity was unaffected by increased threat. Our findings indicate that economic choices are fairly robust to the physiological and emotional changes that result from posture or postural threat.

Coleman, D A; Thayne, W V; Dailey, R A

1985-07-01

We conducted two studies to determine how herd management practices and traits of individual cows affect performance of the herd and of the cow within a herd. Management practices, reproductive performance of the herd, and relationships between management and reproductive performance were characterized on 83 dairy farms with 7596 cows. Data included 21 management variables (e.g., facilities, herd health program, estrous detection program) and 8 performance variables obtained from Dairy Herd Improvement or unofficial records (e.g., size of herd, production, days open). Although varying among herds, annual average herd incidences of reproductive disorders and reproductive performance were similar to those reported. Managerial practices influenced incidences of retained placenta and uterine infection, days open of cows not bred and of all cows, services per conception, and percentages of herd open more than 100 days and culled for low production. Veterinarian was the most consistent variable influencing herd reproductive performance. Data also were collected from production and lifetime records of 2532 cows in 19 herds. Reproductive performance was affected by season of calving, production, maturity, and reproductive disorders. Several cows with extremely poor reproductive records were maintained.

How Piracy is Affecting Economic Development in Puntland, Somalia

Directory of Open Access Journals (Sweden)

Jonathan R. Beloff

2013-01-01

Full Text Available The international community has united in its mission to halt the hijacking of merchant ships in the Gulf of Aden and the Red Sea with a massive naval presence that monitors the vast, strategic seas in which Somali pirates operate. This naval presence consequently has had some success in reducing pirate attacks in 2012, but why are the Somalis turning to piracy in the first place? The economic history of piracy has been well documented with other former “pirate hotspots” worldwide; however, there is little data available on the microeconomic affects of piracy. This article explores the underlying reasons of why Somalis have turned to piracy as a “profession,” and offers recommendations for the international community to eliminate piracy effectively through non-military means.

2018-04-01

Full Text Available This study investigated the effect of economic vulnerability upon competitive advantages, performance, and sustainability of micro-enterprises owned and managed by micro-entrepreneurs who participate in varied development initiatives in Peninsular Malaysia. Upon adopting the cross-sectional design, data were randomly collected from selected 300 micro-entrepreneurs from the eKasih program (national poverty data bank located in four states of Peninsular Malaysia. The quantitative data were collected by conducting structured interview sessions with the respondents held from September until November 2017. The findings revealed that the state of economic vulnerability among the respondents had a significantly negative effect on the aspects of competitive advantages, performance, and sustainability among micro-enterprises in Peninsular Malaysia. Despite of the widely acknowledged and empirically examined effects of socioeconomic antecedents upon micro-enterprise performance, the focus on the effect of a more comprehensive measure of socioeconomic condition, that is, economic vulnerability, among low-income households appears to be scant. Hence, the outcomes of this study are able to provide critical insights for development organizations pertaining to development programs and their effectiveness on economically vulnerable, particularly among low-income households in Peninsular Malaysia.

Full Text Available Physiological and emotional states can affect our decision-making processes, even when these states are seemingly insignificant to the decision at hand. We examined whether posture and postural threat affect decisions in a non-related economic domain. Healthy young adults made a series of choices between economic lotteries in various conditions, including changes in body posture (sitting vs. standing and changes in elevation (ground level vs. atop a 0.8-meter-high platform. We compared three metrics between conditions to assess changes in risk-sensitivity: frequency of risky choices, and parameter fits of both utility and probability weighting parameters using cumulative prospect theory. We also measured skin conductance level to evaluate physiological response to the postural threat. Our results demonstrate that body posture does not significantly affect decision making. Secondly, despite increased skin conductance level, economic risk-sensitivity was unaffected by increased threat. Our findings indicate that economic choices are fairly robust to the physiological and emotional changes that result from posture or postural threat.

Using a Feedback Environment to Improve Creative Performance: A Dynamic Affect Perspective.

Science.gov (United States)

Gong, Zhenxing; Zhang, Na

2017-01-01

Prior research on feedback and creative performance has neglected the dynamic nature of affect and has focused only on the influence of positive affect. We argue that creative performance is the result of a dynamic process in which a person experiences a phase of negative affect and subsequently enters a state of high positive affect that is influenced by the feedback environment. Hierarchical regression was used to analyze a sample of 264 employees from seven industry firms. The results indicate that employees' perceptions of a supportive supervisor feedback environment indirectly influence their level of creative performance through positive affect (t2); the negative affect (t1) moderates the relationship between positive affect (t2) and creative performance (t2), rendering the relationship more positive if negative affect (t1) is high. The change in positive affect mediates the relationship between the supervisor feedback environment and creative performance; a decrease in negative affect moderates the relationship between increased positive affect and creative performance, rendering the relationship more positive if the decrease in negative affect is large. The implications for improving the creative performances of employees are further discussed.

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

Nation-State Size, Ethnic Diversity and Economic Performance in the Advanced Capitalist Countries

DEFF Research Database (Denmark)

Patsiurkoa, Natalka; Campbell, John L.; Hall, John A.

2013-01-01

This paper examines the proposition that the economic performance of advanced capitalist countries depends on their size and ethnic composition. As such it blends insights from two important literatures in comparative political economy. One is exemplified by the work of Peter Katzenstein, who wrote...... the classic treatise on the relationship between nation-state size and economic performance. Another is illustrated by the work of Ernest Gellner, whose work suggested that economic performance depends on the ethnic composition of the nation-state. The argument is tested on pooled data from 30 advanced...... capitalist countries for the 1985 through 2007 period. Regression analysis confirms that ethnically homogenous countries tend to have stronger rates of economic growth during this period than ethnically heterogeneous countries but that neither the size of countries nor the interaction of size and ethnic...

Highlights: • Operation conditions significantly affect energy & economic performance of SLDCS. • Control parameters in three areas were optimized by Multi-Population Genetic Algorithm. • Solar collector area showed the greatest effect on system performance for humid areas. • Desiccant concentration showed greatest effect on system performance for dry areas. • Requirement of collector area, heating water and desiccant flow rates for humid areas is highest. - Abstract: Operation conditions significantly affect the energy and economic performance of solar-assisted liquid desiccant cooling systems. This study optimized the system control parameters for buildings in different climates, i.e., Singapore (hot and humid), Beijing (moderate) and Boulder (hot and dry), with a multi-parameter optimization based on the Multi-Population Genetic Algorithm to obtain optimal system performance in terms of relatively maximum electricity saving rate with a minimum cost payback period. The results indicated that the selection of operation parameters is significantly influenced by climatic conditions. The solar collector installation area exhibited the greatest effect on both energy and economic performance in humid areas, and the heating water flow rate was also important. For dry areas, a change in desiccant concentration had the largest effect on system performance. Although the effect of the desiccant flow rate was significant in humid cities, it appeared to have little influence over buildings in dry areas. Furthermore, the requirements of the solar collector installation area in humid areas were much higher. The optimized area was up to 70 m"2 in Singapore compared with 27.5 m"2 in Boulder. Similar results were found for the flow rates of heating water and the desiccant solution. Applying the optimization, humid cities could achieve an electricity saving of more than 40% with a six-year payback period. The optimal performance for hot and dry areas of a 38% electricity

2016-01-01

Social anxiety is characterized by increased emotional reactivity to social stimuli, but results of studies focusing on affective reactions of socially anxious subjects in the situation of social exposition are inconclusive, especially in the case of endocrinological measures of affect. This study was designed to examine individual differences in endocrinological and affective reactions to social exposure as well as in performance on a speech task in a group of students (n = 44) comprising subjects with either high or low levels of social anxiety. Measures of salivary cortisol and positive and negative affect were taken before and after an impromptu speech. Self-ratings and observer ratings of performance were also obtained. Cortisol levels and negative affect increased in both groups after the speech task, and positive affect decreased; however, group × affect interactions were not significant. Assessments conducted after the speech task revealed that highly socially anxious participants had lower observer ratings of performance while cortisol increase and changes in self-reported affect were not related to performance. Socially anxious individuals do not differ from nonanxious individuals in affective reactions to social exposition, but reveal worse performance at a speech task. © 2015 S. Karger AG, Basel.

Full Text Available he objective of this study was to identify and quantify the most representative factor affecting the economic impact of mastitis in dairy cattle herds in order to establish those that should receive greater attention from farmers and technicians to reduce the economic impact of this important disease. A simulation study was conducted with the CU$TO MASTITE program, considering 324 different herds and using combinations of the following factors: somatic cell count (250,000; 500,000; 750,000 and 1,000,000 somatic cells/mL milk; production scale (50; 100 and 150 lactating cows; productivity per animal (10; 20 and 30 L/cow/day; average annual incidence of clinical mastitis (1%; 7% and 15%, and involuntary culling rate due to mastitis (2%; 4% and 6%. Preventive measures included expenses with monitoring [culture and antibiogram, bulk tank somatic cell count (BTSCC, and individual somatic cell counts], pre- and post-dipping, vaccination, treatment of dry cows, and maintenance of the milking machine. Only treatments of clinical cases were considered as curative measures. The impact of mastitis was estimated as total losses plus expenses with prevention and treatment of clinical cases. The mean incidence of clinical mastitis (MIM and BTSCC were significant (P<0.05 in five of the seven models analyzed [economic impact per lactating cow (ILC, economic impact per liter of milk (ILM, economic impact of curative treatment per liter of milk (CTM, economic impact of milk disposal/liter of sold milk (IMD, and economic impact of reduction in production per liter of milk (IRM]. However, the standardized coefficient for MIM was higher in three indicators (ILC, IMD and CTM, a fact rendering this factor more representative when compared to BTSCC, which also had five significant indicators. Comparison of the medians of curative treatments and preventive measures per lactating cow revealed an excellent cost/benefit ratio. These findings demonstrate that both

There are a lot of differences between these two evaluation programs in terms of their main objectives, assessment items, and evaluation methods by item. When considering the recent evaluation trend of being more concerned with the objective and scientifically well-founded base of judgment than the qualitative results data, there seems to be much supplement and improvement points in both evaluation programs. Firstly, the MSIP's evaluation program which is known as 'The performance analysis of national R and D program in Korea is applying the principle of ex-post evaluation for the overall performances of R and D activities focusing on the scientific and technological outputs, economic effects, and social performances such as the training of science and engineering personnel. Its report has been done and published by the collaboration of MSIP and KISTEP(Korea Institute of Science and Technology Evaluation and Planning). There seems to be a trend that the economic contributions to the national economy and the industries by national R and D projects have been underestimated due to the difficulties of not presenting properly the reliable quantitative effects even though they have contributed not only to the real economy and economic growth but to the industrial productions and public benefits. The key reasons to this phenomenon might be the deficiency of perception for evaluation tools and methodologies development and the original difficulty of evaluation for R and D performances. Especially the evaluation results for national R and D projects could impact on the investment decision on the long-term national R and D program, with being based on the investment efficiency or the necessity and urgency which might be represented by evaluation results.

Murdock, Kyle W; LeRoy, Angie S; Fagundes, Christopher P

2017-08-01

The aim of this paper is to develop a further understanding of the relationship between early-life socio-economic status (SES) and adult health disparities. This was accomplished through evaluation of state indicators of positive and negative affect as mechanisms through which early-life SES was associated with susceptibility to a rhinovirus (i.e. the common cold). Analyses were conducted among 286 adults in a viral challenge study in which participants were exposed to a rhinovirus via nasal drops and cold symptoms were evaluated over a period of 5 days. Participant age, body mass index, sex, education, ethnicity, pre-challenge virus-specific antibody titres and subjective adult SES, along with virus type and season of participation, were included as covariates. Early-life SES was associated with cold incidence through state positive affect, but not state negative affect. In addition, contrast analysis indicated that the indirect effect through state positive affect was stronger than the indirect effect through state negative affect. Findings provide further support for early-life SES being an important variable associated with adult health, and that state self-reported positive affect may be an underlying mechanism associated with susceptibility to rhinoviruses.

Highlights: ►To conduct the comprehensive exergy and economic analysis for advanced combined cycle power plant. ►To study three different HRSG configurations, dual and triple pressure HRSG, based on thermodynamic relations. ►To have a better performance assessment of the system studied using exergy and economic criteria. - Abstract: In the present research study, the effect of HRSG pressure levels on exergy efficiency of combined cycle power plants is investigated. Hence, three types of gas turbine combined cycles, with the same gas turbine as a topping cycle are evaluated. A double pressure, and two triple pressure HRSGs (with and without reheat) are modeled. The results show how an increase in the number of pressure levels of the HRSG affect the exergy losses due to heat transfer in the HRSG and the exhaust of flue gas to the stack. Moreover, the results show that an increase in the number of pressure levels affects the exergy destruction rate in HRSG, and as a result, it causes a tangible increase in exergy efficiency of the whole cycle. The results from thermodynamic analysis show that the losses due to heat transfer in the HRSG and the exhaust of flue gas to the stack in a triple pressure reheat combined cycle are less than the other cases. From the economic analysis, it is found that increasing the number of pressure levels of steam generation leads to an increase for the total and specific investment cost of the plant for about 6% and 4% respectively. The net present value (NPV) of the plant increases for about 7% for triple pressure reheat compared to with the double pressure CCPP. Therefore, the results of economic analysis show that it is economically justifiable to increase the number of pressure levels of steam generation in HRSG.

Local versus Global Environmental Performance of Dairying and Their Link to Economic Performance: A Case Study of Swiss Mountain Farms

2016-12-01

Full Text Available Complying with the carrying capacity of local and global ecosystems is a prerequisite to ensure environmental sustainability. Based on the example of Swiss mountain dairy farms, the goal of our research was firstly to investigate the relationship between farm global and local environmental performance. Secondly, we aimed to analyse the relationship between farm environmental and economic performance. The analysis relied on a sample of 56 Swiss alpine dairy farms. For each farm, the cradle-to-farm-gate life cycle assessment was calculated, and the quantified environmental impacts were decomposed into their on- and off-farm parts. We measured global environmental performance as the digestible energy produced by the farm per unit of global environmental impact generated from cradle-to-farm-gate. We assessed local environmental performance by dividing farm-usable agricultural area by on-farm environmental impact generation. Farm economic performance was measured by work income per family work unit, return on equity and output/input ratio. Spearman’s correlation analysis revealed no significant relationship, trade-offs or synergies between global and local environmental performance indicators. Interestingly, trade-offs were observed far more frequently than synergies. Furthermore, we found synergies between global environmental and economic performance and mostly no significant relationship between local environmental and economic performance. The observed trade-offs between global and local environmental performance mean that, for several environmental issues, any improvement in global environmental performance will result in deterioration of local environmental performance and vice versa. This finding calls for systematic consideration of both dimensions when carrying out farm environmental performance assessments.

Scientific data on the performance of collegiate female tennis players during the menstrual phases are scarce. Double-blind, counter-balanced, crossover trials were conducted to examine whether tennis performance was affected during menstruation, with and without dehydroepiandrosterone sulfate (DHEA-S) supplementation. Ten Division 1 collegiate tennis players (aged 18-22 years) were evenly assigned into placebo-supplemented and DHEA-supplemented (25 mg/day) trials. Treatments were exchanged among the participants after a 28-day washout. Tennis serve performance was assessed on the first day of menstrual bleeding (day 0/28) and on days 7, 14 and 21. Mood state was unaltered during the menstrual cycles in both trials. The lowest tennis serve performance score (speed times accuracy) occurred on day 14 (P=0.06 vs day 0; P=0.01 vs day 21) in both placebo and DHEA trials. Decreased performance on day 14 was explained by decreased accuracy (P=0.03 vs day 0/28; P=0.01 vs day 21), but not velocity itself. Isometric hip strength, but not quadriceps strength, was moderately lower on day 14 (P=0.08). Increasing plasma DHEA-S (by ~65%) during the DHEA-supplemented trial had no effects on mood state, sleep quality or tennis serve performance. We have shown that menses does not affect serve performance of collegiate tennis players. However, the observed decrement in the accuracy of serve speed near ovulation warrants further investigation.

The objective of the study is to examine the long-run and causal relationship between environmental logistics performance indicators (ELPI) and growth-specific factors in a panel of 15 selected global ranked logistics countries over a period of 2007-2015. This study is exclusive as we utilized a number of LPI factors including logistics performance, logistics competence, and logistics infrastructure with mediation of sustainable factors, i.e., carbon dioxide (CO 2 ), fossil fuel, and greenhouse gas (GHG) emissions in a region. The results show that the per capita income, industry, manufacturing, and service share to GDP is affected by CO 2 emissions and GHG emissions. Logistics competence and infrastructure promote economic growth and sectoral value added, while energy demand and FDI inflows both are prerequisite for sustainable agriculture in a region. The causal relationships confirm that more energy demand results in an increase in economic growth, industry value added, and the service sector (i.e., feedback hypothesis), while the sustainable supply chain system improves energy demand, FDI inflows, economic growth, and sectoral growth (i.e., conservation hypothesis) in a panel of countries.

2013-06-01

This study examined implications of the economic downturn that began in December 2007 for the Community Youth Development Study (CYDS), a longitudinal randomized controlled trial of the Communities That Care (CTC) prevention system. The downturn had the potential to affect the internal validity of the CYDS research design and implementation of science-based prevention in study communities. We used archival economic indicators and community key leader reports of economic conditions to assess the extent of the economic downturn in CYDS communities and potential internal validity threats. We also examined whether stronger economic downturn effects were associated with a decline in science-based prevention implementation. Economic indicators suggested the downturn affected CYDS communities to different degrees. We found no evidence of systematic differences in downturn effects in CTC compared to control communities that would threaten internal validity of the randomized trial. The Community Economic Problems scale was a reliable measure of community economic conditions, and it showed criterion validity in relation to several objective economic indicators. CTC coalitions continued to implement science-based prevention to a significantly greater degree than control coalitions 2 years after the downturn began. However, CTC implementation levels declined to some extent as unemployment, the percentage of students qualifying for free lunch, and community economic problems worsened. Control coalition implementation levels were not related to economic conditions before or after the downturn, but mean implementation levels of science-based prevention were also relatively low in both periods.

The diversity literature expects that an equal mix of men and women improves performance, but existing studies show very weak associations. This paper argues that gender diversity does matter, but that the relationship is more complex than assumed. Based on motivational crowding theory, we argue...... that men and women respond differently to economic incentives. We analyze how gender, incentives and the perception of these incentives at research institutions affect organizational performance, measured as the number of scientific publications. Using data from 2000-2005, the analysis includes 162 Danish...... research institutions (17 government research institutions and subunits of 10 universities). The main conclusion is that gender diversity has a modest, but positive impact on organizational output, and that women and men seem to react differently when economic incentives are introduced....

In this study we perform ranking of analytical procedures for 3-monochloropropane-1,2-diol determination in soy sauces by PROMETHEE method. Multicriteria decision analysis was performed for three different scenarios - metrological, economic and environmental, by application of different weights to decision making criteria. All three scenarios indicate capillary electrophoresis-based procedure as the most preferable. Apart from that the details of ranking results differ for these three scenarios. The second run of rankings was done for scenarios that include metrological, economic and environmental criteria only, neglecting others. These results show that green analytical chemistry-based selection correlates with economic, while there is no correlation with metrological ones. This is an implication that green analytical chemistry can be brought into laboratories without analytical performance costs and it is even supported by economic reasons.

Full Text Available Economic status played an important role in the modulation of economic decision making. The present fMRI study aimed at investigating how economic status modulated behavioral and neural responses to unfairness in a modified Ultimatum Game (UG. During scanning, participants played as responders in the UG, and they were informed of the economic status of proposers before receiving offers. At the behavioral level, higher rejection rates and lower fairness ratings were revealed when proposers were in high economic status than in low economic status. Besides, the most time-consuming decisions tended to occur at lower unfairness level when the proposers were in high (relative to low economic status. At the neural level, stronger activation of left thalamus was revealed when fair offers were proposed by proposers in high rather than in low economic status. Greater activation of right medial prefrontal cortex was revealed during acceptance to unfair offers in high economic status condition rather than in low economic status condition. Taken together, these findings shed light on the significance of proposers’ economic status in responders’ social decision making in UG.

Highlights: • An exergo-economic analysis is carried out for a combined cycle power plant. • An overall performance index (OPI) is defined to analyze the power plant. • Four performance indicators and three scenarios are considered in the analysis. • The optimum configuration of the power plant differs for each scenarios considered. - Abstract: An exergo-economic analysis is carried out for a combined cycle power plant using the first law and the second law of thermodynamics, and the economic principles while incorporating GT PRO/PEACE Software Packages. An overall performance index (OPI) is defined to assess and analyze the optimum operational and design configurations of the power plant. Four performance indicators are considered for the analysis; namely, energy efficiency (ENE), exergy efficiency (EXE), levelized cost of electricity (COE), and the total investment (TI) cost. Three possible scenarios are considered in which different weight factor is assigned to the performance indicators when assessing the performance. These scenarios are: (i) the conventional case in which the levelized cost of electricity is given a high priority, (ii) environmental conscious case in which the exergy efficiency is given a high priority, and (iii) the economical case in which the total cost of investment is given a high priority. It is shown that the optimum size and the configuration of the power plant differ for each scenarios considered. The selection and optimization of the size and configuration of the power plant are found to be depending on the user priorities and the weight factors assigned to the performance indicators.

Highlights: • Review of main optimization tools in the field of waste management. • Different optimization methods are applied. • Different fractions are analyzed. • There is focus on different parameters in different geographical regions. • More research is needed which encompasses both recycling and energy solutions. - Abstract: Strategic and operational decisions in waste management, in particular with respect to investments in new treatment facilities, are needed due to a number of factors, including continuously increasing amounts of waste, political demands for efficient utilization of waste resources, and the decommissioning of existing waste treatment facilities. Optimization models can assist in ensuring that these investment strategies are economically feasible. Various economic optimization models for waste treatment have been developed which focus on different parameters. Models focusing on transport are one example, but models focusing on energy production have also been developed, as well as models which take into account a plant’s economies of scale, environmental impact, material recovery and social costs. Finally, models combining different criteria for the selection of waste treatment methods in multi-criteria analysis have been developed. A thorough updated review of the existing models is presented, and the main challenges and crucial parameters that need to be taken into account when assessing the economic performance of waste treatment alternatives are identified. The review article will assist both policy-makers and model-developers involved in assessing the economic performance of waste treatment alternatives

Full Text Available The term responsible entrepreneurship refers to economic success of a business by the inclusion of social and environmental considerations into a company’s operational processes. It satisfies customers’ demands, whilst also managing the expectations of employees, suppliers and the surrounding community. In general, the term Social Corporate Responsibility means a positive contribution to society including management of enterprise’s environmental impacts. The major determinants of the CSR values can be explored such as economic, cultural and leadership factors. Corporate Social Responsibility has been receiving increased attention also from bodies which give certification to companies with CSR in practice. There are different certificates which companies can apply for, if being „responsible“, such as SA 8000, GRI, AA1000, IiP or ISO26000. The aim of this paper is to introduce various certificates, namely SA 8000 and look in details on economic data of 9 companies, chosen from 25 in the Czech Republic, which received this label.Both traditional and modern indicators for assessment of business entities’ economic performance within the entity sample are employed as the inclusion of the economic factors on the CSR. Indices of credibility in order to evaluate the financial status of sample entities are utilised as well. The mentioned economic analysis is managed both in the period before the implementation of the certified CSR system and in the ex-post period. The results of economic analysis in the period before receiving the SA8000 certificate are evaluated using the mathematic-statistical methods to reveal development trend regarding their economic performance and to conduct comparison to respective industrial means.

Full Text Available Quantifying the economic and financial performance in public universities represents a current, very interesting and quite a controversial matter of debate given that the accounting information realm is not sufficient explored through the financial analysis. The paper focuses on the ways of measuring the economic and financial performance in public universities in Romania, having as main purpose to provide a set of assessing indicators, by adapting the financial analysis paradigm existing for the private sector, to the public sector particularities. The specific objectives refer to the rentability, self-financing capacity, efficiency of the university expenditures and risk analysis, and the research approach is developed in the context in which either the national law or the international one do not regulate specific indicators for the economic and financial performance analysis within the public sector institutions

Full Text Available The recent financial crisis that loomed the global economy was considered more inclusive than any other period of financial turmoil in the past 60 years. This paper evaluates the implications of the global economic meltdown on the Nigerian Capital Market Performance using the market capitalization of the Nigerian Stock Exchange as a major indicator. When the global economic meltdown came, it poses a recession on the Market Capitalization and the volume of share index of the Nation. This study depends entirely on secondary data in form of annual aggregate time series data of Market capitalization (dependent variable, exchange rate, interest rate, inflation rate, market share index with Dummy variable to represent the period of economic crisis. Ordinary least square of multiple regressions was used to analyze the data into econometric model while F-statistics was used to test for the formulated hypothesis. This study depicts that the global economic meltdown has a negative effect on the Capital Market Performance. It was therefore recommended that the Federal government and the regulatory agencies (CBN, NSE, SEC etc. should come up with intervention and fiscal policies that will suppress these effects and jumpstart the capital market and that the policies should be properly implemented and monitored.

Regional Economic Resilience: Resistance and Recoverability of Resource-Based Cities during Economic Crises in Northeast China

Directory of Open Access Journals (Sweden)

Juntao Tan

2017-11-01

Full Text Available This paper quantitatively analyzes the economic resilience of resource-based cities (RBCs in Northeast China in terms of resistance and recoverability during two economic crises: the Asian financial crisis and the global financial crisis. Moreover, it analyzes the main factors that affected regional resilience. There are three main findings. First, the RBCs in general demonstrated poor resistance during both recessions, but there were variations among the different types of RBCs. Petroleum and metal cities demonstrated the most resistance, whereas coal cities performed the worst. Second, the influential factors affecting economic resilience varied across the two economic cycles, but location advantage, research and development (R and D intensity, foreign trade dependence ratio, and supporting policies had positive effects on resilience during both economic cycles, while the proportion of employed persons in resource industries had a negative effect. Industrial diversity had a weak and ambiguous effect on resilience. Third, the secondary industry was more resilient during the Asian financial crisis, but the tertiary industry was more resilient during the global financial crisis. This shift may be attributed to both the nature of the crises and the strength of the sectors at the time of the crises.

Huntsinger, Jeffrey R; Ray, Cara

2016-09-01

Considerable research shows that positive affect improves performance on creative tasks and negative affect improves performance on analytic tasks. The present research entertained the idea that affective feelings have flexible, rather than fixed, effects on cognitive performance. Consistent with the idea that positive and negative affect signal the value of accessible processing inclinations, the influence of affective feelings on performance on analytic or creative tasks was found to be flexibly responsive to the relative accessibility of different styles of processing (i.e., heuristic vs. systematic, global vs. local). When a global processing orientation was accessible happy participants generated more creative uses for a brick (Experiment 1), successfully solved more remote associates and insight problems (Experiment 2) and displayed broader categorization (Experiment 3) than those in sad moods. When a local processing orientation was accessible this pattern reversed. When a heuristic processing style was accessible happy participants were more likely to commit the conjunction fallacy (Experiment 3) and showed less pronounced anchoring effects (Experiment 4) than sad participants. When a systematic processing style was accessible this pattern reversed. Implications of these results for relevant affect-cognition models are discussed.

Virginia Barba-Sánchez

2016-10-01

Full Text Available Environmental sustainability in the winery sector is receiving increased attention from governments, environmental groups, and consumers. The aim of this study is to explore the relationship between the degree of proactivity of a firm’s environmental strategies and its business performance. The novelty of this research work lies in its definition of business performance, which includes business environmental performance in terms of reducing the firm’s environmental impacts and eco-efficiency in the use of resources such as water, energy, and raw materials, in addition to its economic performance. A model is proposed and tested using a sample of 312 Spanish wineries. Data were analysed using partial least squares path modelling (PLS-PM. The fitness and robustness of the structural model proved adequate. The results indicate positive correlation of environmental proactivity with economic and environmental performance. Although environmental proactivity improves business performance, it has a greater impact on reducing environmental impacts and improving eco-efficiency.

The effect of perceived regional accents on individual economic behavior: a lab experiment on linguistic performance, cognitive ratings and economic decisions.

Directory of Open Access Journals (Sweden)

Stephan Heblich

Full Text Available Does it matter if you speak with a regional accent? Speaking immediately reveals something of one's own social and cultural identity, be it consciously or unconsciously. Perceiving accents involves not only reconstructing such imprints but also augmenting them with particular attitudes and stereotypes. Even though we know much about attitudes and stereotypes that are transmitted by, e.g. skin color, names or physical attractiveness, we do not yet have satisfactory answers how accent perception affects human behavior. How do people act in economically relevant contexts when they are confronted with regional accents? This paper reports a laboratory experiment where we address this question. Participants in our experiment conduct cognitive tests where they can choose to either cooperate or compete with a randomly matched male opponent identified only via his rendering of a standardized text in either a regional accent or standard accent. We find a strong connection between the linguistic performance and the cognitive rating of the opponent. When matched with an opponent who speaks the accent of the participant's home region--the in-group opponent--, individuals tend to cooperate significantly more often. By contrast, they are more likely to compete when matched with an accent speaker from outside their home region, the out-group opponent. Our findings demonstrate, firstly, that the perception of an out-group accent leads not only to social discrimination but also influences economic decisions. Secondly, they suggest that this economic behavior is not necessarily attributable to the perception of a regional accent per se, but rather to the social rating of linguistic distance and the in-group/out-group perception it evokes.

Daily fluctuations in positive affect positively co-vary with working memory performance.

Brose, Annette; Lövdén, Martin; Schmiedek, Florian

2014-02-01

Positive affect is related to cognitive performance in multiple ways. It is associated with motivational aspects of performance, affective states capture attention, and information processing modes are a function of affect. In this study, we examined whether these links are relevant within individuals across time when they experience minor ups and downs of positive affect and work on cognitive tasks in the laboratory on a day-to-day basis. Using a microlongitudinal design, 101 younger adults (20-31 years of age) worked on 3 working memory tasks on about 100 occasions. Every day, they also reported on their momentary affect and their motivation to work on the tasks. In 2 of the 3 tasks, performance was enhanced on days when positive affect was above average. This performance enhancement was also associated with more motivation. Importantly, increases in task performance on days with above-average positive affect were mainly unrelated to variations in negative affect. This study's results are in line with between-person findings suggesting that high levels of well-being are associated with successful outcomes. They imply that success on cognitively demanding tasks is more likely on days when feeling happier. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Background. Social scientists have suggested that cultural diversity in a nation leads to societal instability. However, societal instability may be affected not only by within-nation on ?? diversity, but also diversity between a nation and its neighbours or ?? diversity. It is also necessary to distinguish different domains of diversity, namely linguistic, ethnic and religious, and to distinguish between the direct effects of diversity on societal instability, and effects that are mediated by economic conditions. Methodology/Principal Findings. We assembled a large cross-national dataset with information on ?? and ?? cultural diversity, economic conditions, and indices of societal instability. Structural equation modeling was used to evaluate the direct and indirect effects of cultural diversity on economics and societal stability. Results show that different type and domains of diversity have interacting effects. As previously documented, linguistic ?? diversity has a negative effect on economic performance, and we show that it is largely through this economic mechanism that it affects societal instability. For ?? diversity, the higher the linguistic diversity among nations in a region, the less stable the nation. But, religious ?? diversity has the opposite effect, reducing instability, particularly in the presence of high linguistic diversity. Conclusions. Within-nation linguistic diversity is associated with reduced economic performance, which, in turn, increases societal instability. Nations which differ linguistically from their neighbors are also less stable. However, religious diversity between, neighboring nations has the opposite effect, decreasing societal instability.

Social scientists have suggested that cultural diversity in a nation leads to societal instability. However, societal instability may be affected not only by within-nation or alpha diversity, but also diversity between a nation and its neighbours or beta diversity. It is also necessary to distinguish different domains of diversity, namely linguistic, ethnic and religious, and to distinguish between the direct effects of diversity on societal instability, and effects that are mediated by economic conditions. We assembled a large cross-national dataset with information on alpha and beta cultural diversity, economic conditions, and indices of societal instability. Structural equation modeling was used to evaluate the direct and indirect effects of cultural diversity on economics and societal stability. Results show that different types and domains of diversity have interacting effects. As previously documented, linguistic alpha diversity has a negative effect on economic performance, and we show that it is largely through this economic mechanism that it affects societal instability. For beta diversity, the higher the linguistic diversity among nations in a region, the less stable the nation. But, religious beta diversity has the opposite effect, reducing instability, particularly in the presence of high linguistic diversity. Within-nation linguistic diversity is associated with reduced economic performance, which, in turn, increases societal instability. Nations which differ linguistically from their neighbors are also less stable. However, religious diversity between neighboring nations has the opposite effect, decreasing societal instability.

The clear association between reports of sleep disturbance and poor school performance has been documented for sleepy adolescents. This study extends that research to students outside the adolescent age grouping in an associated school setting (98 middle school students, 67 high school students, and 64 college students). Reported restless legs and periodic limb movements are significantly associated with lower GPA's in junior high students. Consistent with previous studies, daytime sleepiness was the sleep variable most likely to negatively affects high school students. Sleep onset and maintenance insomnia were the reported sleep variables significantly correlated with poorer school performance in college students. This study indicates that different sleep disorder variables negatively affect performance at different age and educational levels.

Full Text Available Among management activities, the strategic function retains increasingly attention of authors being interested in SME's (small and medium-sized enterprise performance. Indeed, there are many authors who think that by following a strategy building formal process, SMEs can increase chances of success, while others consider that by trusting their manager’s intuition, SMEs can stimulate creativity and develop important competitive advantages at the same time. Further to these controversies, we aim through this communication to partake in this debate mattering to both researchers and managers by revising the relation between strategic planning and SMEs' economic performance. So as to handle this matter, we verify nearby 100 Moroccan SMEs, the degree of importance they grant to strategic planning. We also examine how SMEs strategic planning may or not be associated with their economic performance as measured by average variation sales over the last three years.

Full Text Available The main objective of this paper is to measure the currency misalignment of the Croatian kuna and to reveal whether it affects economic growth for the period 2001 (Q1 to 2013 (Q3. The estimate relies on recent cointegration techniques, VAR models and Granger causality tests. The findings show that there are two misalignment sub-periods for the Croatian kuna: undervaluation in the period from 2000Q1 to 2007Q4 and overvaluation in the period from 2008Q1 to 2013Q3. The evidence reveals that for the whole sample period, the Granger causality goes from misalignments (MISA to GDP growth under the 10 percent significance level. However, for the two sub-periods no evidence of Granger causality from MISA to GDP growth or vice versa is found. The research also reveals that the currency misalignments in the observed period are relatively small.

The subject of the research is a set of processes of correlation analysis of economic and environmental indicators of the oil and gas producing industry. The urgency of the task of mitigating anthropogenic climate change caused by rising concentrations of greenhouse gases in the atmosphere is proven. Statistical data on emissions for the past 15 years are analyzed, change trends are identified. The authors establish the cause of the growth in greenhouse gas emissions, the energy sector being the main contributor. A description of the mechanism of the effect of greenhouse gases on the climate system is provided. The requirements set by international agreements and Russian documents aimed at reducing greenhouse gas emissions are unified. The main gases that cause the greenhouse effect are identified, their classification and brief characteristics are provided in the article. The necessity to promote the monitoring of greenhouse gas emissions and reporting system at the global level is substantiated. The purpose of the advanced metering system is to obtain relevant and reliable data for timely response to and planned reduction of greenhouse gas emissions. In accordance with the recommendations of the international standard for non-financial reporting, GRI, the effectiveness of reducing greenhouse gas emissions should be disclosed in the aspect of “Emissions”. The progress of economic science has made it important to take into account the natural component, and the value of bioresources will increase over time, therefore, the company's economic development can not be isolated. In accordance with the hypothesis, it is assumed that the economy and ecology are interrelated and affect each other.

Intermodal Freight Transport on the Right Track? Environmental and economic performances and their trade-off

International Nuclear Information System (INIS)

Kim, Nam Seok

2010-01-01

This dissertation aims to evaluate environmental and economic performances of an intermodal freight transport system and to estimate the trade-off between CO2 emissions, which is presented as an indicator of environmental performance, and freight costs, which indicate the economic performance of the intermodal freight system. The truck-only system is always regarded as the counterpart of the intermodal freight system in this dissertation. To examine the environmental performance of the intermodal freight system, CO2 emissions generated from all the processes in the intermodal chain, such as pre-haulage and post-haulage, long distance haulage, and transshipment, are estimated considering different sources that generate electricity and transmission loss of electricity (Chapters 3 and 4). To examine the economic performance of the system, two approaches are considered: (1) finding the intermodal breakeven distance for which the intermodal system is more competitive than the truck-only system (Chapter 5); (2) examining the economies of scale in the intermodal network and finding the route/system choice that minimizes the total freight transportation costs (Chapter 6). Finally, this dissertation attempts to find the trade-off between CO2 emissions (representing the environmental performance) and freight transportation cost (representing the economic performance) (Chapter 7)

Full Text Available The economic crisis presented unprecedented challenges to nonprofit organizations to sustain their services. In this study, we examined both financial and management factors that influence the financial performance of nonprofit organizations during times of economic stress. In particular, we investigated whether strategic planning and plan implementation, revenue diversification, and board involvement help nonprofit organizations deal with financial uncertainty and strengthen financial performance. Despite the negative impacts that the economic downturn had on nonprofit organizations, we found that the implementation of strategic plans can help nonprofit organizations reduce financial vulnerability. Our findings call attention to key management factors that influence the financial performance of nonprofit organizations.

This allows a reduction of almost 80% in the residual organic material being deposited in the earth or rivers, avoiding deposits accumulating on riverbeds and negative environmental impacts. It also allows substantial savings in terms of energy. The general aim of this study is to investigate, with the implementation of biodigesters, how eco-innovation practices contribute to the economic and environmental performance of cassava processing companies in Paraná State. Through qualitative research, the method employed an exploratory approach and intensive multiple-case analyses, with data collected through semi-structured interviews. The study showed that the eco-innovation practices that were adopted aided the economic and environmental performance of the companies in question. The study contributes to academia with scientific research on biodigester technology using the residual organic material of cassava for sustainable development. It also contributes to the corporate universe by demonstrating an opportunity for sustainable innovation with improved economic and environmental performance, which can be extrapolated to other industrial segments.

Full text: The inter-state target programme of the Eurasian Economic Community 'Reclamation of areas of the Eurasian Economic Community member-states affected by the uranium mines' includes assessment of impact of these facilities on the public health at the adjacent areas and estimation of potential risk of radiation induced diseases. This work will be carried out as follows: collection of indicators of the State medical statistic reporting by areas of natural uranium mining and milling waste storage to be reclaimed; data input to the database, data verification, calculation of relative indexes and estimation of potential risk of radiation induced diseases; comparative analysis of the public health at inspected and reference areas, estimation of potential risk of radiation induced diseases; development of recommendations on enhancing medical service of the population. Burnasyan Federal Medical Biophysical Centre developed the method of data collection in order to assess and to perform the comparative analysis of the public health. At the early stage of the programme, for the purpose of the comparative analysis of the public health at the contaminated areas, we are going to identify areas affected by uranium plants and some reference areas with approximately same quality of health-care service. When collecting medical data of the public, the special attention will be paid to malignant neoplasm incidence, including trachea, bronchus, lung cancer and psycho-somatic diseases (hypertension, coronary heart disease, peptic ulcer and duodenal ulcers, and others). This kind of data will be collected as the number of registered patients by sex and age groups in the report of the state medical statistics 'Information on malignant neoplasm incidence over 1990 - 2014' (according to the reporting form 'Information on the number of diseases registered at the area under the clinic service'). The statistical bodies of the Eurasian Economic Community member-states will organize the

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.

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

1992-01-01

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

YouTube is often used as a companion medium or a learning supplement. One of the educational places that often uses is Jogja Audio School (JAS) which focuses on music production education. Music production is a difficult material to learn, especially at the audio mastering. With tutorial contents from YouTube, students find it easier to learn and understand audio mastering and improved their learning performance. This study aims to validate the role of YouTube as a medium of learning in improving student’s learning performance by looking at the factors that affect student learning performance. The sample involves 100 respondents from JAS at audio mastering level. The results showed that student learning performance increases seen from factors that have a significant influence of motivation, instructional content, and YouTube usefulness. Overall findings suggest that YouTube has a important role to student learning performance in music production education and as an innovative and efficient learning medium.

Rigoli, Francesco; Pavone, Enea Francesco; Pezzulo, Giovanni

2012-01-01

IN NEUROSCIENCE AND PSYCHOLOGY, AN INFLUENTIAL PERSPECTIVE DISTINGUISHES BETWEEN TWO KINDS OF BEHAVIORAL CONTROL: instrumental (habitual and goal-directed) and Pavlovian. Understanding the instrumental-Pavlovian interaction is fundamental for the comprehension of decision-making. Animal studies (as those using the negative auto-maintenance paradigm), have demonstrated that Pavlovian mechanisms can have maladaptive effects on instrumental performance. However, evidence for a similar effect in humans is scarce. In addition, the mechanisms modulating the impact of Pavlovian responses on instrumental performance are largely unknown, both in human and non-human animals. The present paper describes a behavioral experiment investigating the effects of Pavlovian conditioned responses on performance in humans, focusing on the aversive domain. Results showed that Pavlovian responses influenced human performance, and, similar to animal studies, could have maladaptive effects. In particular, Pavlovian responses either impaired or increased performance depending on modulator variables such as threat distance, task controllability, punishment history, amount of training, and explicit punishment expectancy. Overall, these findings help elucidating the computational mechanisms underlying the instrumental-Pavlovian interaction, which might be at the base of apparently irrational phenomena in economics, social behavior, and psychopathology.

The present study aims at recognizing the social influence, study habits and health factors affecting scholastic performances of adolescents and to compare these factors among the adolescents between two categories of school. A total of 1230 adolescents (13-18 yrs) were screened. Data was collected by personal interview, using the teenage screening questionnaire, Trivandrum, between May 2004 and November 2005. A total 615 students from corporation and private schools were studied. 39.76% (489) were high achievers, 13.5% (166) were low achievers with p poor study habits and social factors were increased in low achievers of corporation schools. On multivariate analysis, the predictor variables for poor scholastic performance were adolescent having refractory error, not having help for study at home, not doing home work regularly, not solving question bank papers and reading only before examinations. It is feasible and worthwhile to identify the determinants of scholastic performance and plan intervention strategies at each school. The results of this study highlight the importance of implementing newer strategies, focusing on strict study patterns and creating the conducive school and home environment for study, so as to achieve better scholastic performances.

Economic measures of performance

Cogeneration systems can reduce the total cost of utility service, and, in some instances where power is sold to an electric utility, can even produce a positive net revenue stream. This is, the total cogeneration revenue is greater than the cogeneration system's operating cost plus the cost of supplemental fuel and power. Whether it is sited at an existing facility or new construction, cogeneration systems do require an incremental investment over and above that which would be required if the end user were to utilize more conventional utility services. While the decision as to whether or not one should invest in cogeneration may consider such intangibles as predictability of future utility costs, reliability of electrical supply and the quality of that supply, the decision ultimately becomes one of basic economics. This chapter briefly reviews several economic measures with regard to ease of use, accuracy and financial objective

Is There an Economical Running Technique? A Review of Modifiable Biomechanical Factors Affecting Running Economy.

Science.gov (United States)

Moore, Isabel S

2016-06-01

Running economy (RE) has a strong relationship with running performance, and modifiable running biomechanics are a determining factor of RE. The purposes of this review were to (1) examine the intrinsic and extrinsic modifiable biomechanical factors affecting RE; (2) assess training-induced changes in RE and running biomechanics; (3) evaluate whether an economical running technique can be recommended and; (4) discuss potential areas for future research. Based on current evidence, the intrinsic factors that appeared beneficial for RE were using a preferred stride length range, which allows for stride length deviations up to 3 % shorter than preferred stride length; lower vertical oscillation; greater leg stiffness; low lower limb moment of inertia; less leg extension at toe-off; larger stride angles; alignment of the ground reaction force and leg axis during propulsion; maintaining arm swing; low thigh antagonist-agonist muscular coactivation; and low activation of lower limb muscles during propulsion. Extrinsic factors associated with a better RE were a firm, compliant shoe-surface interaction and being barefoot or wearing lightweight shoes. Several other modifiable biomechanical factors presented inconsistent relationships with RE. Running biomechanics during ground contact appeared to play an important role, specifically those during propulsion. Therefore, this phase has the strongest direct links with RE. Recurring methodological problems exist within the literature, such as cross-comparisons, assessing variables in isolation, and acute to short-term interventions. Therefore, recommending a general economical running technique should be approached with caution. Future work should focus on interdisciplinary longitudinal investigations combining RE, kinematics, kinetics, and neuromuscular and anatomical aspects, as well as applying a synergistic approach to understanding the role of kinetics.

Full Text Available Globalisation has opened economies more, exposing them to more international shocks and increasing the challenges to which domestic economic policies must respond. This paper provides a starting point for the analysis of the impact of international economic developments on the South African economy by means of graphical illustrations, correlations coefficients and in some cases a VAR analysis. Although this paper has shed some light on the importance of international economic developments on the South African economy, more rigorous econometric investigation is needed to validate the arguments and to address many of the unresolved questions.

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

2016-04-01

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

This article examines how an anti-graft body, the Economic and Financial Crime Commission (EFCC), has fared in reducing the incidence of corruption in Nigeria, in particular, bank fraud, Internet scam, and bad governance. It first discusses the corruption situation in Nigeria by highlighting public office holders who have been associated with corruption charges. A Likert-type scale is used in designing the questionnaire for data collection. Descriptive and chi-square analyses are used, and results reveal that the performance of the EFCC has been affected by government interference (p .05), bad governance and advance fee fraud have recorded appreciable reduction (p < .05). Areas of success as well as challenges that need to be addressed are identified. Specifically, it is recommended that the bill that established EFCC should be amended to reduce government interference and improve its manpower development, especially in the areas of fraud and Internet scam detection.

To perform SWOT (strengths, weaknesses, opportunities, and threats) analysis of a clinical laboratory as an economic model that may be used to improve business performance of laboratories by removing weaknesses, minimizing threats, and using external opportunities and internal strengths. Impact of possible threats to and weaknesses of the Clinical Laboratory at Našice General County Hospital business performance and use of strengths and opportunities to improve operating profit were simulated using models created on the basis of SWOT analysis results. The operating profit as a measure of profitability of the clinical laboratory was defined as total revenue minus total expenses and presented using a profit and loss account. Changes in the input parameters in the profit and loss account for 2008 were determined using opportunities and potential threats, and economic sensitivity analysis was made by using changes in the key parameters. The profit and loss account and economic sensitivity analysis were tools for quantifying the impact of changes in the revenues and expenses on the business operations of clinical laboratory. Results of simulation models showed that operational profit of €470 723 in 2008 could be reduced to only €21 542 if all possible threats became a reality and current weaknesses remained the same. Also, operational gain could be increased to €535 804 if laboratory strengths and opportunities were utilized. If both the opportunities and threats became a reality, the operational profit would decrease by €384 465. The operational profit of the clinical laboratory could be significantly reduced if all threats became a reality and the current weaknesses remained the same. The operational profit could be increased by utilizing strengths and opportunities as much as possible. This type of modeling may be used to monitor business operations of any clinical laboratory and improve its financial situation by implementing changes in the next fiscal

1981-05-01

The economic performance of selected passive solar heating and cooling technologies which incorporate energy storage is assessed by using a set of uniform assumptions and methodologies. Where data are available, a given system is assessed at more than one geographical location. Results are obtained in the form of both payback period and net present value for residential applications, and in terms of net present value only for industrial/commercial uses. Results indicate that ventilated trombe walls, solar roof ponds, and certain night effect/floor storage strategies are cost effective, but night effect/rock bed cooling is not. Results also show that, although direct gain out-performs trombe walls in most parts of the country, both direct gain and trombe walls usually produce a net savings in the residential sector. Generally, however, tax regulations result in net economic loss for direct gain and trombe walls used to heat industrial and commercial buildings.

Does Innovation Performance Depend on Economic Growth?: The Case of a Country in Transition

Directory of Open Access Journals (Sweden)

Andrzej H Jasinski

2011-12-01

Full Text Available This paper is an attempt to analyze a possible influence of economic growth on innovation performance. Econometric model based on principal component analysis is the research tool. Poland, as a country in transition, is here a case-study. The analysis has confirmed an interesting pattern: in 1989-2007, corporate innovation performance was changing, in principle, in the same direction as macro-economic changes but with a one-to-two-year delay. This is some proof that the innovation activity followed the cyclical development of the national economy. Innovation performance was demand-driven, i.e., pulled by demand resulting from the economy's recovery and high economic growth. So, technological innovation appeared to be highly sensitive to the general economic situation in Poland as a transitional economy. Economic growth seems to be a kind of tag-boat pulling innovation activities in the business sector.Este artículo intenta analizar una posible influencia del crecimiento económico en el desempeño de la innovación. La herramienta de investigación empleada es el modelo econométrico basado en un componente principal de análisis. El estudio de caso es Polonia, una economía en transición. El análisis ha confirmado un patrón interesante: durante el periodo 1989-2007, el desempeño de la innovación cambió, en principio, en la misma dirección que los cambios macroeconómicos pero con un retraso de uno a dos años. Esto muestra de algún modo que la actividad innovadora correspondió al desarrollo cíclico de la economía nacional. El desempeño innovador se orientó por la demanda, es decir, una demanda impulsada por la recuperación económica y el alto crecimiento económico. Por lo tanto, la innovación tecnológica parece ser muy sensible a la situación económica en general de Polonia, como economía en transición. El crecimiento económico parece ser una especie de motor que impulsa las actividades innovadoras del sector de negocios.

Preparatory power posing affects nonverbal presence and job interview performance.

Science.gov (United States)

Cuddy, Amy J C; Wilmuth, Caroline A; Yap, Andy J; Carney, Dana R

2015-07-01

The authors tested whether engaging in expansive (vs. contractive) "power poses" before a stressful job interview--preparatory power posing--would enhance performance during the interview. Participants adopted high-power (i.e., expansive, open) poses or low-power (i.e., contractive, closed) poses, and then prepared and delivered a speech to 2 evaluators as part of a mock job interview. All interview speeches were videotaped and coded for overall performance and hireability and for 2 potential mediators: verbal content (e.g., structure, content) and nonverbal presence (e.g., captivating, enthusiastic). As predicted, those who prepared for the job interview with high- (vs. low-) power poses performed better and were more likely to be chosen for hire; this relation was mediated by nonverbal presence, but not by verbal content. Although previous research has focused on how a nonverbal behavior that is enacted during interactions and observed by perceivers affects how those perceivers evaluate and respond to the actor, this experiment focused on how a nonverbal behavior that is enacted before the interaction and unobserved by perceivers affects the actor's performance, which, in turn, affects how perceivers evaluate and respond to the actor. This experiment reveals a theoretically novel and practically informative result that demonstrates the causal relation between preparatory nonverbal behavior and subsequent performance and outcomes.

Cognitive-behavioral models highlight the conjoint roles of self-focused attention (SFA), post-event processing (PEP), and performance appraisals in the maintenance of social anxiety. SFA, PEP, and biased performance appraisals are related to social anxiety; however, limited research has examined how SFA affects information-processing following social events. The current study examined whether SFA affects the relationships between performance appraisals and PEP following a social event.. 137 participants with high (n = 72) or low (n = 65) social anxiety were randomly assigned to conditions of high SFA or low SFA while engaging in a standardized social performance. Subsequent performance appraisals and PEP were measured. Immediate performance appraisals were not affected by SFA. High levels of SFA led to a stronger, inverse relationship between immediate positive performance appraisals and subsequent negative PEP. High levels of SFA also led to a stronger, inverse relationship between negative PEP and changes in positive performance appraisals.. Future research should examine whether the current findings, which involved a standardized social performance event, extend to interaction events as well as in a clinical sample. These findings suggest that SFA affects the processing of positive information following a social performance event. SFA is particularly important for understanding how negative PEP undermines positive performance appraisals.. Published by Elsevier Ltd.

Full Text Available Foreign Direct Investment (FDI not only affects the economic growth but also affects the environmental protection of the host country. With China’s background of pursuing green growth, we need to consider the performance of FDI from the economic and environmental benefit aspects. On this basis, using slacks-based measure directional distance function (SBMDDF to build up green growth efficiency, economic efficiency and environmental efficiency indexes, empirical research on FDI in 104 Chinese cities from 2004 to 2011 has shown that: (1 Different cities have differences in their green growth efficiency. Shenzhen city is always efficient in green economic growth. (2 Overall, FDI is positive on Chinese cities’ green growth. (3 When the green growth efficiency is broken down into economic efficiency and environmental efficiency, FDI promotes China’s economic green growth through both environmental benefits and economic benefits. (4 The effect of FDI differs in different sectors. FDI in the emission-intensive sector promotes green efficiency mainly through the improvement of economic efficiency. FDI in the non-emission-intensive sector promotes economic efficiency, environmental efficiency and green efficiency.

The profit and production of an average Finnish blue fox farm was simulated using a deterministic bio-economic farm model. Risk was included using Arrow-Prat absolute risk aversion coefficient and profit variance. Risk-rated economic values were calculated for pregnancy rate, litter loss, litter size, pelt size, pelt quality, pelt colour clarity, feed efficiency and eye infection. With high absolute risk aversion, economic values were lower than with low absolute risk aversion. Economic values were highest for litter loss (18.16 and 26.42 EUR), litter size (13.27 and 19.40 EUR), pregnancy (11.99 and 18.39 EUR) and eye infection (12.39 and 13.81 EUR). Sensitivity analysis showed that selection pressure for improved eye health depended strongly on proportion of culled animals among infected animals and much less on the proportion of infected animals. The economic value of feed efficiency was lower than expected (6.06 and 8.03 EUR). However, it was almost the same magnitude as pelt quality (7.30 and 7.30 EUR) and higher than the economic value of pelt size (3.37 and 5.26 EUR). Risk factors should be considered in blue fox breeding scheme because they change the relative importance of traits. © 2016 Blackwell Verlag GmbH.

Highlights: • Coupling a thermoelectric power generation (TEG) to a heat sink is presented. • Review the classifications and parameters affecting performance of the TEG with heat sink. • Discuss different mathematical models of the heat sinks. • The passive heat sinks are most appropriate because of the inherent efficiency of TEG. • Medium temperature range below 300 °C is found to be most suitable for HPHS. - Abstract: In recent years, there have been growing interests in key areas related to global warming resulting from environmental emissions, and the diminishing sources of fossil fuel. The increased interest has led to significant research efforts towards finding novel technologies in clean energy production. Consequently, the merits of a thermo-electric generator (TEG) have promised a revival of alternative means of producing green energy. It is, however, impractical to account for the cost of thermal energy input to the TEG which is in the form of final waste heat. This is because the technology presents critical limitations in determining its cost efficiency nor its economic disadvantages. This paper reviews the principles of thermo-electric power production, as well the materials use, performance achieved, and application areas. The paper also takes a particular deliberation on TEG heat sinks geometries and categories. The review emphasizes more on the TEG performance while considering a number of heat sink parameters related to its performance.

1998-01-01

When two tones of slightly different frequency are presented separately to the left and right ears the listener perceives a single tone that varies in amplitude at a frequency equal to the frequency difference between the two tones, a perceptual phenomenon known as the binaural auditory beat. Anecdotal reports suggest that binaural auditory beats within the electroencephalograph frequency range can entrain EEG activity and may affect states of consciousness, although few scientific studies have been published. This study compared the effects of binaural auditory beats in the EEG beta and EEG theta/delta frequency ranges on mood and on performance of a vigilance task to investigate their effects on subjective and objective measures of arousal. Participants (n = 29) performed a 30-min visual vigilance task on three different days while listening to pink noise containing simple tones or binaural beats either in the beta range (16 and 24 Hz) or the theta/delta range (1.5 and 4 Hz). However, participants were kept blind to the presence of binaural beats to control expectation effects. Presentation of beta-frequency binaural beats yielded more correct target detections and fewer false alarms than presentation of theta/delta frequency binaural beats. In addition, the beta-frequency beats were associated with less negative mood. Results suggest that the presentation of binaural auditory beats can affect psychomotor performance and mood. This technology may have applications for the control of attention and arousal and the enhancement of human performance.

Few studies in medical education have studied effect of quality of motivation on performance. Self-Determination Theory based on quality of motivation differentiates between Autonomous Motivation (AM) that originates within an individual and Controlled Motivation (CM) that originates from external sources. To determine whether Relative Autonomous Motivation (RAM, a measure of the balance between AM and CM) affects academic performance through good study strategy and higher study effort and compare this model between subgroups: males and females; students selected via two different systems namely qualitative and weighted lottery selection. Data on motivation, study strategy and effort was collected from 383 medical students of VU University Medical Center Amsterdam and their academic performance results were obtained from the student administration. Structural Equation Modelling analysis technique was used to test a hypothesized model in which high RAM would positively affect Good Study Strategy (GSS) and study effort, which in turn would positively affect academic performance in the form of grade point averages. This model fit well with the data, Chi square = 1.095, df = 3, p = 0.778, RMSEA model fit = 0.000. This model also fitted well for all tested subgroups of students. Differences were found in the strength of relationships between the variables for the different subgroups as expected. In conclusion, RAM positively correlated with academic performance through deep strategy towards study and higher study effort. This model seems valid in medical education in subgroups such as males, females, students selected by qualitative and weighted lottery selection.

Radiotherapy is among the most efficient treatment methods of cancer. However, a radiotherapy base needs a substantial financial investment, especially before the beginning of its operation, and in some cases, in developing countries such a huge investment may cause some financial disturbances for a hospital concerned. To assess the influence of investments modernizing the radiotherapy base in the period between 2000 and 2007 on the financial condition of the oncology hospital in the region with population of about 3 million. Financial reports and medical statistics for the period between 2000 and 2007 from the studied oncology hospital and a recognized staffing model, as well as data on epidemiological situation of the region have been used to calculate the economic effects of financial investment in the radiotherapy base. The growth of RT therapeutic potential has been driven by two cost-effective investment programmes. The total amount invested in both programmes was PLN 127,191,000. The number of radiotherapy patients treated in the hospital increased from 2301 in 2000 to 4799 in 2007 with a the same number of five therapeutic machines, although all five of them were replaced over that period. Investments modernizing the radiotherapy base lead to a significant increase in depreciation and operating costs, which adversely affects financial results of the hospital. Long term trends showed that investments had positive influence on hospital performance shown both in increased income and larger number of patients treated.

Full Text Available In this paper we intend to describe the economic implications of mass-media in correlation with the recent socio-economic changes generated by the economic crisis. We take into consideration the dual market on which mass-media evolves: the mass-media products market, and the advertising market, keeping in mind that the behavior of a mass-media institution on one market, can have direct implication on the other market. We analyze the relation between mass-media and the public (audience, the cost for creating mass-media products, the ways in which mass-media reduces costs and the ways of increasing their profits. As mass-media must always adapt to the social changes and to the public, we take our analysis further and we describe how the recent economic changes influenced the mass-media consumption trends and mass-media profits on all the main communication channels: TV, radio, outdoor, internet, newspapers/magazines. This analysis is performed at both a global and a local level, for Romania. In the end we predict how other key changes may affect the economic model approach of the mass-media institutions on short and middle terms.

Osmundsen, Petter; Aven, Terje; Erik Vinnem, Jan

2008-01-01

There is an increased use of key performance indicators and incentive schemes in the petroleum industry. Applying modern incentive theory, we explore what implications this management trend has for injury and major accident prevention efforts and safety. Can economic incentives be designed for accident prevention activities? In cases where this is not possible, what are the challenges for the safety efforts? In particular, how are safety efforts affected by enhanced economic incentives for other performance dimensions like production and rate of return? Can safety be neglected? What remedies are available?

The objectives of this study were to determine the risk factors for development of postpartum ovarian cysts by evaluating several reproductive factors in individual cows, and to determine the economic impact of ovarian cysts on subsequent reproductive performance in dairy herds in Korea. The data, including cow parity, abnormal puerperium, endometritis, body condition score (BCS), and breeding status were collected from 634 cows in 9 dairy herds. We used logistic regression to evaluate the effects of these factors on ovarian cysts. A stepwise procedure, used to obtain the appropriate model with alpha=0.05, revealed that cow parity was the most important risk factor for ovarian cyst development within 8 weeks postpartum, while development of endometritis and BCS loss>or=1 from the dry period to 8 weeks postpartum were the most important risk factors for ovarian cyst development beyond 8 weeks postpartum. The occurrence of ovarian cysts beyond 8 weeks postpartum prolonged (Pconception (77 days), and increased (Prate (7.8%), while ovarian cyst development within 8 weeks postpartum did not affect (P>0.05) the mean intervals from calving to first service and conception or the culling rate. The economic loss resulting from the occurrence of ovarian cysts was estimated at approximately 823,996 won ($687) due to effects on the cost of nutrition, average growth of calves, labor and medical costs, and culling. These results suggest that cow parity is correlated with the development of ovarian cysts within 8 weeks postpartum, and endometritis and BCS loss>or=1 from the dry period to 8 weeks postpartum are correlated with the development of ovarian cysts after 8 weeks postpartum, which decreases reproductive performance and results in economic loss in dairy herds in Korea.

Full Text Available This study examined the effect of government expenditure on its disaggregated level on economic growth in a sample of 20 sub-Saharan African Countries over the period of 1980-2010 in a dynamic panel data model. The result from Generalised Method of Moments (GMM revealed an inverse relationship between productive government expenditure and economic growth in sub-Sahara Africa. Also, productive government expenditures were not actually productive most especially when financed by non-distortonary government tax revenue in sub-Saharan African countries. The study concluded that the productive government expenditure and its corresponding source of the mode of financing were counterproductive for economic performance in the African countries.

Finding the economics in economic entomology.

Science.gov (United States)

Onstad, David W; Knolhoff, Lisa M

2009-02-01

To recommend new pest management tactics and strategies to farmers and policy makers, economic entomologists must evaluate the economics of biologically reasonable approaches. We collected data to determine how frequently these economic evaluations occur. We discovered from our survey of entomological journals representing the discipline of economic entomology that papers published since 1972 include economic evaluations of pest management tactics. At least 85% of these analyses were performed by entomologists and not economists. Much of the research on economic evaluations is performed without special funds granted by agencies separate from the authors' institutions. In the United States, USDA competitive grants supported 20% of the economic evaluations published since 2000. However, only approximately 12% of the projects funded since 2000 by three sections of the USDA (Crops at Risk, Risk Avoidance and Mitigation Program, and Pest Management Alternatives Program) resulted in publications concerning economic evaluations. If the purpose of economic entomology is to ultimately determine the value of different kinds of tactics, the discipline may need to take steps to enhance the research that supports these evaluations.

2011-01-01

Aim To perform SWOT (strengths, weaknesses, opportunities, and threats) analysis of a clinical laboratory as an economic model that may be used to improve business performance of laboratories by removing weaknesses, minimizing threats, and using external opportunities and internal strengths. Methods Impact of possible threats to and weaknesses of the Clinical Laboratory at Našice General County Hospital business performance and use of strengths and opportunities to improve operating profit were simulated using models created on the basis of SWOT analysis results. The operating profit as a measure of profitability of the clinical laboratory was defined as total revenue minus total expenses and presented using a profit and loss account. Changes in the input parameters in the profit and loss account for 2008 were determined using opportunities and potential threats, and economic sensitivity analysis was made by using changes in the key parameters. The profit and loss account and economic sensitivity analysis were tools for quantifying the impact of changes in the revenues and expenses on the business operations of clinical laboratory. Results Results of simulation models showed that operational profit of €470 723 in 2008 could be reduced to only €21 542 if all possible threats became a reality and current weaknesses remained the same. Also, operational gain could be increased to €535 804 if laboratory strengths and opportunities were utilized. If both the opportunities and threats became a reality, the operational profit would decrease by €384 465. Conclusion The operational profit of the clinical laboratory could be significantly reduced if all threats became a reality and the current weaknesses remained the same. The operational profit could be increased by utilizing strengths and opportunities as much as possible. This type of modeling may be used to monitor business operations of any clinical laboratory and improve its financial situation by

Full Text Available Sven BraeutigamOxford Centre for Human Brain Activity, University of Oxford, Oxford, United KingdomAbstract: For about a hundred years, theorists and traders alike have tried to unravel and understand the mechanisms and hidden rules underlying and perhaps determining economically relevant behavior. This review focuses on recent developments in neuroeconomics, where the emphasis is placed on two directions of research: first, research exploiting common experiences of urban inhabitants in industrialized societies to provide experimental paradigms with a broader real-life content; second, research based on behavioral genetics, which provides an additional dimension for experimental control and manipulation. In addition, possible limitations of state-of-the-art neuroeconomics research are addressed. It is argued that observations of neuronal systems involved in economic behavior converge to some extent across the technologies and paradigms used. Conceptually, the data available as of today raise the possibility that neuroeconomic research might provide evidence at the neuronal level for the existence of multiple systems of thought and for the importance of conflict. Methodologically, Bayesian approaches in particular may play an important role in identifying mechanisms and establishing causality between patterns of neural activity and economic behavior.Keywords: neuroeconomics, behavioral genetics, decision-making, consumer behavior, neural system

Health economists are increasingly interested in integrated care in order to support decision-makers to find cost-effective solutions able to tackle the threat that chronic diseases pose on population health and health and social care budgets. However, economic evaluation in integrated care is still in its early years, facing several difficulties. The aim of this paper is to describe the unique nature of integrated care as a topic for economic evaluation, explore the obstacles to perform economic evaluation, discuss methods and techniques that can be used to address them, and set the basis to develop a research agenda for health economics in integrated care. The paper joins the voices that call health economists to pay more attention to integrated care and argues that there should be no more time wasted for doing it. PMID:28316543

The Effects of Self-Focus On Affect and Vertical Jump Performance of NCAA Athletes

2015-04-01

Full Text Available Self-focused attention is often associated with a process of evaluation that has implications for affect, motivation and performance. However, this topic has received little attention in elite sport. Thus, the aim of this study was to understand the relationship between self-focused attention, affective responses and physical performance of successfully (n=12 and unsuccessful (n=12 NCAA athletes. Each athlete was presented with a self-focused and other-focused condition. They provided ratings of positive affect and then completed vertical squat jumps after each stimulus condition. Significant interactions were observed between stimulus condition and athlete performance group for all dependent variables. Successful athletes demonstrated significantly more positive affect, and greater jump height and energy output following the self-focused condition. The opposite trend was observed for unsuccessful athletes. These findings highlight the potential for self-focused attention to enhance or detract from sport performance based on the direction of self-discrepancies.

2015-08-01

Full Text Available Recent economic downturns have led many countries to reduce health spending dramatically, with the World Health Organization raising concerns over the effects of this, in particular among the poor and vulnerable. With the provision of appropriate health care, the population of a country could have better health, thus strengthening the nation’s human capital, which could contribute to economic growth through improved productivity. How much should countries spend on health care? This study aims to estimate the optimal health care expenditure in a growing economy. Applying the experiences of countries from the Organization for Economic Co-Operation and Development (OECD over the period 1990 to 2009, this research introduces the method of system generalized method of moments (GMM to derive the design of the estimators of the focal variables. Empirical evidence indicates that when the ratio of health spending to gross domestic product (GDP is less than the optimal level of 7.55%, increases in health spending effectively lead to better economic performance. Above this, more spending does not equate to better care. The real level of health spending in OECD countries is 5.48% of GDP, with a 1.87% economic growth rate. The question which is posed by this study is a pertinent one, especially in the current context of financially constrained health systems around the world. The analytical results of this work will allow policymakers to better allocate scarce resources to achieve their macroeconomic goals.

Full Text Available Sustainable development and, therefore, globalization require new standards of performance that exceeds the economic field, both for domestic companies as well as international ones. So, these standards should be integrated into corporate strategy development to ensure sustainability of activities undertaken by harmonizing the economic, social and environmental objectives. For sustainable development of an entity, value creation can not be seen in strictly financial terms, therefore any strategies that are defined by entities concerns not only the quantitative aspects (economic-financial but also qualitative aspects (social and environmental. This study attempts to address the issue of building a set of indicators to assess overall performance and it stops at each of the three dimensions of performance, namely economic performance, social performance and environmental performance. In this scientific approach we try to stop on one of the priorities of economic research that is finding indicators that better reflect the three dimensions of performance. What indicators would best represent the overall performance?, What indicators would best represent the financial performance?, What indicators would best represent social performance?, What would be the best indicators of environmental performance? During this scientific approach will try to answer each of these questions through the empirical research conducted. To do this research we focused on statistical population consisting of the following categories of analysts: analysts from academic environment (Cluj-Napoca, Bucharest, Timisoara, Iasi, Craiova, Sibiu, Pitesti, Galati and financial analysts from the specific departments of the Financial Investment Services Company (Broker SA, BT Securities, Target Capital, Tradeville, Estinvest, Intercapital, KBC Securities, etc.. This distinction was made because we believe that in determining the optimal structure of such a model we need the views of

Full Text Available The role of the legal system in generating economic performance is enjoying increased attention inliterature. Our scientific endeavour tries to underline, from an original perspective, the incoherence whichcharacterises the Romanian law and judicial system; at the same time, it also offers a few solutions meant torestore and reconsider the role of public institutions in the legislative and judicial process. Considering thefacts presented in our study, the existence of efficient legal institutions, who enforce contracts ex post whileusing the judicial infrastructure (courts and judicial procedures, is more than critical for the formation of anagreement of will between contracting parties, thus generating economic performance for privateorganisations by reducing transaction costs and by limiting the opportunism of economic agents. Equity,predictability, transparency and reduced costs are advantages deriving from the legal enforcement ofcontracts, which stimulate competition and trade, while reducing the risks associated with different types oftransactions. Thus, it is necessary to implement an anti-corruption policy, to enhance the predictability of thelaw-making process, to reconsider and restore the attributions of institutions involved in the Romanianlegislative and judiciary process, in order to promote proper civil and commercial judicial procedures,together with the analysis of the possibility to acknowledge jurisprudence as a source of law.

Ruia, Aparna; Gupta, Rajul Kumar; Bandyopadhyay, Gargi; Gupta, Rajshree R

2018-01-01

Good economic growth is considered synonymous with good nutrition. In recent past, some states (like Bihar and Gujarat) have seen unprecedented economic growth. Despite this and introducing plethora of programs (including integrated child development scheme [ICDS]) to reduce malnutrition, one state might be performing well in reducing malnutrition whereas other with equally high economic growth rate might lag behind. Is mere economic growth good enough to alleviate malnutrition? The aim of the article is to document a critical comparative analysis of malnutrition with special emphasis on ICDS (with respect to finances, infrastructure, training, performance) in the two economically resurgent states of Gujarat and Bihar. An exploratory study using secondary data sources (for ICDS performance) to critically analyze malnutrition status in Bihar and Gujarat. Gujarat, which was criticized for placing excessive emphasis on economic growth, has shown sharp improvement in combating malnutrition. Undernourished children declined from 73.04% in 2007 to 25.09% in 2013, with just 1.6% being severely malnourished. On the other hand, Bihar too exhibited an impressive economic growth but still languishes at bottom with malnutrition rate of 82%. A high economic growth does not have automatic immediate positive gains on malnutrition alleviation.

Marius Cristian Milos

2012-01-01

Full Text Available The users of financial statements need information regarding the resources of an economic entity and also data regarding the way in which the entity’s management is using resources. This information helps users to quantify efficiency and performance within an entity. There are many stakeholders who do show interest in an entity’s financial reports, including existing and potential investors, employees, lenders, suppliers, customers, regulators and other government agencies and not the least the common citizens. The main purpose of this paper is to highlight the importance of the performance measurement and to discuss possible reporting methods. Performance is a concept that raises many questions regarding the most accurate way or the best method for quantifying and reporting performance at the company level .So if financial performance indicators are considered to offer an accurate image of the situation of a company, the modern approach which focuses also on non-financial indicators offers new perspectives upon performance measurement, which may be really expressive and also based on simplicity.

Economic Conditions and Factors Affecting New Nuclear Power Deployment

Energy Technology Data Exchange (ETDEWEB)

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

Highlights: • Global environmental protection of using alternative fuel. • Economic aspects of palm oil biodiesel in Malaysia. • Tribological characteristics of palm oil biodiesel in engine components. • Engine performance and emission of palm oil biodiesel. • Effect of temperature on density and kinematic viscosity for various biodiesel. - Abstract: The high cost of energy supplies and the growing concern over the dependency on fossil fuels have impelled many countries to search for renewable and alternative energy sources. The extensive use of fossil fuels for transportation and power generation all over the world have caused the supply of fossil fuels to continuously decrease and have aggravated environmental pollution. Searching for alternative fuels has become imperative to reduce pollution and address the problems on fossil fuels. Vegetable oil fuels, such as palm oil biodiesel, serve as alternative forms of energy and are currently being studied, particularly as a diesel fuel substitute. The purpose of this study is to review the potential of palm oil as an energy source and alternative diesel fuel in terms of its performance, environmental impact, wear characteristics, and economic considerations. Compared with other vegetable oils, palm oil is a relatively sustainable, environment-friendly, less expensive, and economically beneficial potential source of energy. Palm oil plantation and production is a major industry in Malaysia, contributing to the economic growth and development of the country. The properties of palm oil biodiesel, namely, high oxidation stability, good cold properties, cetane number, and higher viscosity, makes it a suitable diesel substitute. Compared with other vegetable oils and petroleum diesel fuels, palm oil is associated with better engine performance, higher specific fuel consumption, and shorter ignition delay. Use of palm oil also reduces exhaust emission of hydrocarbon, carbon monoxide, carbon dioxide, and smoke, but

Thermodynamic and economic performances optimization of an organic Rankine cycle system utilizing exhaust gas of a large marine diesel engine

Highlights: • A new parameter is proposed for optimizing economic performance of the ORC system. • Maximal thermodynamic and economic performances of an ORC system are presented. • The corresponding operating pressures in turbine of optimum thermodynamic and economic performances are investigated. • An optimal effectiveness of pre-heater is obtained for the ORC system. - Abstract: The aim of this study is to investigate the thermodynamic and economic performances optimization for an ORC system recovering the waste heat of exhaust gas from a large marine diesel engine of the merchant ship. Parameters of net power output index and thermal efficiency are used to represent the economic and thermodynamic performances, respectively. The maximum net power output index and thermal efficiency are obtained and the corresponding turbine inlet pressure, turbine outlet pressure, and effectiveness of pre-heater of the ORC system are also evaluated using R1234ze, R245fa, R600, and R600a. Furthermore, the analyses of the effects of turbine inlet temperature and cooling water temperature on the optimal economic and thermodynamic performances of the ORC system are carried out. The results show that R245fa performs the most satisfactorily followed by R600, R600a, and R1234ze under optimal economic performance. However, in the optimal thermodynamic performance evaluations, R1234ze has the largest thermal efficiency followed by R600a, R245fa, and R600. The payback periods will decrease from 0.5 year for R245fa to 0.65 year for R1234ze respectively as the system is equipped with a pre-heater. In addition, compared with conventional diesel oil feeding, the proposed ORC system can reduce 76% CO 2 emission per kilowatt-hour

Productive and Economic Performance of Broiler Chickens Subjected to Different Nutritional Plans

Directory of Open Access Journals (Sweden)

JMS Martins

Full Text Available ABSTRACT The objective of the study was to evaluate the effect of nutritional plans on the productive and economic performance of Hubbard Flex broiler chickens. A completely randomized experimental design was applied, consisting of five treatments. Treatments consisted of five different nutritional plans: a basal diet containing the nutrient and energy levels recommended by literature and designated reference diet; two diets containing 1.5% and 3% lower levels than the reference diet; and two diets containing 1.5% and 3% higher levels than the reference diet (-3%, -1.5%, reference plan, +1.5% and +3%. Feed intake (FI, body weight (BW, feed conversion rate (FCR, livability (L and productive efficient index (PEI were determined when broilers were 42 days old. Broilers were processed, and carcass and parts (breast fillet, leg, and wings yields were determined. The economic viablility of the nutitional plans was evaluated as a function of feed cost/kg live and carcass weights, economic efficiency index (EEI, and cost index (CI. Feed intake and the feed conversion rate decreased as dietary nutrient and energy levels increased. Feed cost/kg live weight, economic efficiency index, and cost index cost increased as dietary nutrient and energy levels increased. Feed intake, feed conversion ratio, production efficiency index, and breast yield improved with increasing nutritional and energy levels. However, worse economic results were obtained with higher nutritional and energy levels.

National approach to economic performance indicators for nuclear power plants: USA

International Nuclear Information System (INIS)

2006-01-01

The structure of the US electric power industry comprises a combination of traditional electric utilities and less traditional electricity producing companies. The electric utilities include investor owned, publicly owned, federal and cooperative firms. Approximately three quarters of the electricity generated by utilities is generated by investor owned companies. These utilities are, for the most part, franchised monopolies that have an obligation to provide electricity to all customers within a service area. Most provide for the generation, transmission and distribution of electricity, although the distinctions between these services are breaking down as the electricity industry becomes more deregulated. The shares are publicly traded and their areas of business operation are expanding into new ones, sometimes unrelated to the provision of electricity or even energy. Under deregulation and open market pricing of electricity, the business and financial success of operating nuclear plants must be considered to a much greater extent along with the successful achievement of safety and reliability objectives. In developing strategic and operational goals, nuclear plant managers are required to embrace clear and measurable business objectives and goals that not only assure the achievement of safety and reliability but, in addition, eliminate unnecessary costs and identify investment opportunities. These goals must balance operating and safety risk while optimizing plant revenues and earnings and ultimately ensure the profitability of electricity generating facilities. In doing so, it is essential that plant managers articulate goal achievement through the application of effective, measurable, economic performance indicators. Individual nuclear plants will sell their output competing on electricity price, ultimately to ensure the safe, reliable and economic dispatch of their generation either onto open spot markets or by competitive bidding for bilateral contracts.

This study evaluated the effect of feed allocation and energetic efficiency on technical and economic efficiency of broiler breeder hens using the data envelope analysis methodology and quantified the effect of variables affecting technical efficiency. A total of 288 Ross 708 pullets were placed in individual cages at 16 wk of age and assigned to 1 of 4 feed allocation groups. Three of them had feed allocated on a group basis with divergent BW targets: standard, high (standard x 1.1), and low (standard x 0.9). The fourth group had feed allocated on an individual bird basis following the standard BW target. Birds were classified in 3 energetic efficiency categories: low, average, and high, based on estimated maintenance requirements. Technical efficiency considered saleable chicks as output and cumulative ME intake and time as inputs. Economic efficiency of feed allocation treatments was analyzed under different cost scenarios. Birds with low feed allocation exhibited a lower technical efficiency (69.4%) than standard (72.1%), which reflected a reduced egg production rate. Feed allocation of the high treatment could have been reduced by 10% with the same chick production as the standard treatment. The low treatment exhibited reduced economic efficiency at greater capital costs, whereas high had reduced economic efficiency at greater feed costs. The average energetic efficiency hens had a lower technical efficiency in the low compared with the standard feed allocation. A 1% increment in estimated maintenance requirement changed technical efficiency by -0.23%, whereas a 1% increment in ME intake had a -0.47% effect. The negative relationship between technical efficiency and ME intake was counterbalanced by a positive correlation of ME intake and egg production. The negative relationship of technical efficiency and maintenance requirements was synergized by a negative correlation of hen maintenance and egg production. Economic efficiency methodologies are effective

Cardis, Marco; Casadio, Maura; Ranganathan, Rajiv

2018-01-01

Motor variability plays an important role in motor learning, although the exact mechanisms of how variability affects learning are not well understood. Recent evidence suggests that motor variability may have different effects on learning in redundant tasks, depending on whether it is present in the task space (where it affects task performance) or in the null space (where it has no effect on task performance). We examined the effect of directly introducing null and task space variability using a manipulandum during the learning of a motor task. Participants learned a bimanual shuffleboard task for 2 days, where their goal was to slide a virtual puck as close as possible toward a target. Critically, the distance traveled by the puck was determined by the sum of the left- and right-hand velocities, which meant that there was redundancy in the task. Participants were divided into five groups, based on both the dimension in which the variability was introduced and the amount of variability that was introduced during training. Results showed that although all groups were able to reduce error with practice, learning was affected more by the amount of variability introduced rather than the dimension in which variability was introduced. Specifically, groups with higher movement variability during practice showed larger errors at the end of practice compared with groups that had low variability during learning. These results suggest that although introducing variability can increase exploration of new solutions, this may adversely affect the ability to retain the learned solution. NEW & NOTEWORTHY We examined the role of introducing variability during motor learning in a redundant task. The presence of redundancy allows variability to be introduced in different dimensions: the task space (where it affects task performance) or the null space (where it does not affect task performance). We found that introducing variability affected learning adversely, but the amount of

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.

Do Corruption and Social Trust affect Economic Growth? A Review

DEFF Research Database (Denmark)

Serritzlew, Søren; Sønderskov, Kim Mannemar; Svendsen, Gert Tinggaard

2014-01-01

Two separate literatures suggest that corruption and social trust, respectively, are related to economic growth, although the strengths of the relationships, and the direction of causality, are still debated. In this paper, we review these literatures and evaluate the evidence for causal effects...... of corruption and trust on economic growth, and discuss how corruption and trust are interrelated. The reviews show that absence of corruption and high levels of social trust foster economic growth. The literatures also indicate that corruption has a causal effect on social trust, while the opposite effect...... is more uncertain. In the conclusion, we offer the suggestion that fighting corruption may yield a “double dividend”, as reduced corruption is likely to have both direct and indirect effects on growth....

Knowledge gaps in economic analyses of advanced reactor concepts

Moore, M.; Pencer, J.; Leung, L.K.H.; Sadhankar, R.

2014-01-01

The development of next generation nuclear systems is predicated on improvement in sustainability, safety, proliferation resistance and economics. The economic assessment of the reactor concept is required as early as in the concept development stage. The Generation IV International Forum (GIF) has developed a methodology for economic assessment of the Generation IV (GEN-IV) nuclear energy systems. The GIF economics methodology was used for the assessment of one of the reactor concepts for the Super-Critical Water-cooled Reactors (SCWR), namely the European pressure-vessel type concept referred to as the High Performance Light Water Reactor (HPLWR). The economic analysis involved studying the sensitivity of two main economic indicators, namely, the Levelized Unit Electricity Cost (LUEC) and the Total Capital Investment Cost (TCIC). The knowledge gaps in estimating the capital costs and fuel costs, as well as the uncertainties in other cost parameters affecting the economic assessment of the nuclear energy system in the concept development stage are presented.

2013-01-01

This paper studies the technical, economic, and environmental analysis of wind and photovoltaic power systems connected to a conventional grid. The main interest in such systems is on-site consumption of the produced energy, system hybridization, pooling of resources, and contribution to the environment protection. To ensure a better management of system energy, models have been used for determining the power that the constituting subsystems can deliver under specific weather conditions. Simulation is performed using MATLAB-SIMULINK. While, the economic and environmental study is performed using HOMER software. From an economic point of view, this allows to compare the financial constraints on each part of the system for the case of Adrar site which is located to the northern part of the south of Algeria. It also permits to optimally size and select the system presenting the best features on the basis of two parameters, that is, cost and effectiveness. From an environmental point of view, this study allows highlighting the role of renewable energy in reducing gas emissions related to greenhouse effects. In addition, through a set of sensitivity analysis, it is found that the wind speed has more effects on the environmental and economic performances of grid-connected hybrid (photovoltaic-wind) power systems.

Context In 1997, Congress authorized the Food and Drug Administration (FDA) to grant 6 month extensions of marketing rights through the Pediatric Exclusivity program if industry sponsors complete FDA-requested pediatric trials. The program has been praised for creating incentives for studies in children; it has been criticized as a “windfall” to the innovator drug industry. This critique has been a substantial part of Congressional debate on the program, which is due to sunset in 2007. Objective To quantify the economic return to industry for completing Pediatric Exclusivity. Design Cohort study of programs conducted for Pediatric Exclusivity. We selected 9 drugs that were granted Pediatric Exclusivity. From the final study reports submitted to FDA, we obtained key elements of the clinical trial design and study operations. We estimated the cost of performing each study and converted these into estimates of after-tax cash outflows. We obtained 3-year market sales and converted these into estimates of after-tax cash inflows based upon 6 months of additional market protection. We then calculated the net economic return (cash inflows less outflows) and ratio net return to costs (net economic return divided by cash outflows) for each product. Main Outcome Measures Net economic return and ratio of net return to cost. Results The indications studied reflected a broad representation of the program: asthma, tumors, attention deficit disorder, hypertension, depression/generalized anxiety disorder, diabetes, gastroesophageal reflux, bacterial infection, and bone mineralization. The distribution of net economic return for 6 months of exclusivity varied substantially among products [net return ranged from (−)$8.9 million to (+)$507.9 million; ratio of return to cost ranged from −0.68 to 73.6] Conclusions The economic return for pediatric exclusivity is highly variable. Pediatric Exclusivity, as an incentive to complete much-needed clinical trials in children, can

Open Economy, Institutional Quality, and Environmental Performance: A Macroeconomic Approach

2016-06-01

Full Text Available As the subject of how economic development affects the quality of the natural environment has gained great momentum, this paper focuses on examining the extent to which the openness of a market economy and the quality of the institution affect environmental performance. The majority of the current studies focus on the Environmental Kuznets Curve and the level of economic growth. This paper addresses this question by relating environmental (“Environmental Performance Index” to macroeconomic (Gross Domestic Product per capita, “Open Markets Index” and governance indicators (“Worldwide Governance Indicators”. The sample consists of 75 countries, including all G20 and EU members, comprising “more than 90% of global trade and investment”. Findings show that the Environmental Performance Index is positively correlated to each of the (institutional indicators, so as to confirm that the selected indices are consistent with previous studies, suggesting that environmental performance increases in line with economic development and that good governance increases a country’s levels of environmental protection. By applying factor analysis, an empirical model of the Environmental Performance Index is estimated, suggesting that there is a significant positive correlation between a country’s economic growth, the openness of an economy, high levels of effective governance, and its environmental performance.

Full Text Available This paper investigates whether, and if so, how procedural fairness affects performance evaluation system satisfaction in a UK Police Force. Employing a survey method with samples of detective inspectors and detective chief inspectors with significant managerial responsibilities in a UK Police Force, this study finds that procedural fairness affects performance evaluation system satisfaction. Further analysis reveals that the effect of procedural fairness on performance evaluation system satisfaction is mediated by trust. This study provides empirical evidence on how procedural fairness affects performance evaluation system satisfaction. The results of this study may benefit the designer of performance evaluation systems in police organizations.

Sustainability of processed foods supply chain: Social, economic and territorial performance

Beber Caetano

2016-01-01

Full Text Available In a global market, food companies engaged in sustainable development must now integrate the economic and social component. However the tools to assess it are lacking. Several theoretical frameworks have been developed to define social sustainability and its implementation. The attributional approaches, pathways or capabilities methods have emerged, based on a functional unit of a good or service along the supply chain. This paper proposes a new method to assess social economic and territorial performances of a food chain as a whole on a Territory. It is divided into four components: (i dignity and well-being of workers, (ii contribution to local life, (iii fairness and integrity of business practices, and (iv creation of material and intangible wealth. 50 criteria are used according to international, national or sectoral references. This generic method applicable to any sector of processed food products aims to identify where are the areas of improvement to qualify the sector as socially sustainable. An application to the wine Beaujolais and Burgundy wine was performed from surveys of 35 production and trade operators in 2014. The results show that the sector is particularly effective for the promotion of the territory, local life participation, loyalty and integrity of business practices; some improvement is still possible for the welfare of workers and the creation of material wealth. This method can be coupled with the environmental performance determined by the life cycle analysis in order to assess the sustainability in its entirety.

Niedziółka Dorota

2017-01-01

Full Text Available Currently, power plants in Poland have to work in a very uncomfortable situation. Unstable market conditions and frequent changes in the law may have serious adverse consequences for their economic security. Power plants play a very important role in the economy. The effectiveness of their performance affects the activity of all other businesses. Therefore, it is very important to provide a definition of economic security for the power plants’ sector and the factors determining its level. Maintaining economic security will allow energy generation companies to grow in a sustainable way as well as limit operational risk. A precise definition can also be used to create analytical tools for economic security measurement and monitoring. Proper usage of such tools can help energy generation companies sustain their economic security and properly plan their capital expenditures. The article focuses on the definition of economic security in the “micro” context of a separate business unit (enterprise. We also present an analytical model that measures economic security of a company engaged in the production of energy - a company of strategic importance for the national economy. The model uses macroeconomic variables, variables describing prices of raw material and legal / political stability in the country, as well as selected financial indicators. The appliance of conclusions resulting from the model’s implementation will help provide economic security for companies generating energy.

According to the European Directive 2003/30 'Promotion of the use of biofuels or other renewable fuels for transport' the use of biofuels in the transportation sector should be strongly increased in the next decades in Europe. The purpose of this study was to obtain and present clear data and information to outline environmental and economic performance of different biofuels. Based on a standardised review of the most relevant international studies on transportation systems using biomass, the study presented estimation of ranges for the environmental and economic performance of different biofuels given by the two 'threshold values' and the 'reference value' between these threshold values. These results might be used by different stakeholders as an information source for future activities regarding the use of biofuels in the transportation sector in Europe. This report presents data about the following biofuels: bioethanol, bio-ETBE, biomethanol, bio-MTBE, pure vegetable oil, biodiesel, Fischer-Tropsch diesel, bio-DME, biogas, gaseous biohydrogen, liquid biohydrogen and bio-SNG.

Performing a secondary executive task with affective stimuli interferes with decision making under risk conditions.

Science.gov (United States)

Gathmann, Bettina; Pawlikowski, Mirko; Schöler, Tobias; Brand, Matthias

2014-05-01

Previous studies demonstrated that executive functions are crucial for advantageous decision making under risk and that therefore decision making is disrupted when working memory capacity is demanded while working on a decision task. While some studies also showed that emotions can affect decision making under risk, it is unclear how affective processing and executive functions predict decision-making performance in interaction. The current experimental study used a between-subjects design to examine whether affective pictures (positive and negative pictures compared to neutral pictures), included in a parallel executive task (working memory 2-back task), have an impact on decision making under risk as assessed by the Game of Dice Task (GDT). Moreover, the performance GDT plus 2-back task was compared to the performance in the GDT without any additional task (GDT solely). The results show that the performance in the GDT differed between groups (positive, negative, neutral, and GDT solely). The groups with affective pictures, especially those with positive pictures in the 2-back task, showed more disadvantageous decisions in the GDT than the groups with neutral pictures and the group performing the GDT without any additional task. However, executive functions moderated the effect of the affective pictures. Regardless of affective influence, subjects with good executive functions performed advantageously in the GDT. These findings support the assumption that executive functions and emotional processing interact in predicting decision making under risk.

Health economic choices in old age: interdisciplinary perspectives on economic decisions and the aging mind.

Science.gov (United States)

Nielsen, Lisbeth; Phillips, John W R

2008-01-01

This chapter offers an integrative review of psychological and neurobiological differences between younger and older adults that might impact economic behavior. Focusing on key health economic challenges facing the elderly, it offers perspectives on how these psychological and neurobiological factors may influence decision-making over the life course and considers future interdisciplinary research directions. We review relevant literature from three domains that are essential for developing a comprehensive science of decision-making and economic behavior in aging (psychology, neuroscience, and economics), consider implications for prescription drug coverage and long-term care (LTC) insurance, and highlight future research directions. Older adults face many complex economic decisions that directly affect their health and well-being, including LTC insurance, prescription drug plans, and end of life care. Economic research suggests that many older Americans are not making cost-effective and economically rational decisions. While economic models provide insight into some of the financial incentives associated with these decisions, they typically do not consider the roles of cognition and affect in decision-making. Research has established that older age is associated with predictable declines in many cognitive functions and evidence is accumulating that distinct social motives and affect-processing profiles emerge in older age. It is unknown how these age differences impact the economic behaviors of older people and implies opportunities for path-breaking interdisciplinary research. Our chapter looks to develop interdisciplinary research to better understand the causes and consequences of age-related changes in economic decision-making and guide interventions to improve public programs and overall social welfare.

If the good performance of fusion as technology with no CO 2 emission during normal operation and rather low external costs, reflecting the advantageous environmental and safety characteristics, are considered in future energy regulations, fusion can win considerable market shares in future electricity markets. The economic performance was elaborated for Western Europe for the time period till 2100. The software tool MARKAL widely used in energy research was used to simulate and optimise the development of the Western European energy system. Two different scenarios were considered, the main difference was the interest rate for investments. Stringent CO 2 -emission strategies lead to considerable market shares for fusion. As a comprehensive indicator of the environmental and safety performance of fusion plants the external costs following the ExternE method was used. External costs of fusion are rather low, much below the cost of electricity, and are in the same range as photovoltaics and wind energy. (author)

Luck, Policy or Something Else Entirely? Vietnam’s Economic Performance in 2009 and Prospects for 2010

Directory of Open Access Journals (Sweden)

Adam J. Fforde

Full Text Available Vietnam’s economic performance in 2009 is seen by the Vietnamese government and representatives of the Western donor communities as good, with the effects of the global financial crisis relatively mild. The paper notes a lack of contestation of these mainstream views and locates them within an assessment of major trends in 2009, and medium-term issues. Particular focus is placed upon the policy implications of rural development and the need for a strong rationalisation of the state sector. Remarks upon the political economy of change then permit comments upon interactions between economic performance and gathering social and political concern with the political challenges of transition to so-called ‘middle income’ status, which in many countries has posed novel and tricky problems of adjustment, often requiring major social and political adjustments that have not always been successful. The paper concludes by suggesting that, as in the past, Vietnam’s style of change finds some things easy and others hard, and that this has its reflection in economic policy and performance.

Neonicotinoid insecticides negatively affect performance measures of non‐target terrestrial arthropods: a meta‐analysis

Science.gov (United States)

Main, Anson; Webb, Elisabeth B.; Goyne, Keith W.; Mengel, Doreen C.

2018-01-01

Neonicotinoid insecticides are currently the fastest‐growing and most widely used insecticide class worldwide. Valued for their versatility in application, these insecticides may cause deleterious effects in a range of non‐target (beneficial) arthropods. However, it remains unclear whether strong patterns exist in terms of their major effects, if broad measures of arthropod performance are negatively affected, or whether different functional groups are equally vulnerable. Here, we present a meta‐analysis of 372 observations from 44 field and laboratory studies that describe neonicotinoid effects on 14 arthropod orders across five broad performance measures: abundance, behavior, condition, reproductive success, and survival. Across studies, neonicotinoids negatively affected all performance metrics evaluated; however, magnitude of the effects varied. Arthropod behavior and survival were the most negatively affected and abundance was the least negatively affected. Effects on arthropod functional groups were inconsistent. Pollinator condition, reproductive success, and survival were significantly lower in neonicotinoid treatments compared to untreated controls; whereas, neonicotinoid effects on detritivores were not significant. Although magnitude of arthropod response to neonicotinoids varied among performance measures and functional groups, we documented a consistent negative relationship between exposure to neonicotinoid insecticides in published studies and beneficial arthropod performance.

Full Text Available Examining a popular political notion, this article presents results from a series of Spearman Rho calculations conducted to investigate relationships between countries’ rankings on international tests of mathematics and science and future economic competitiveness as measured by the 2006 World Economic Forum’s Growth Competitiveness Index (GCI. The study investigated the existence of relationships between international test rankings from three different time periods during the last 50 years of U.S. education policy development (i.e., 1957–1982, 1983–2000, and 2001–2006 and 2006 GCI ranks. It extends previous research on the topic by investigating how GCI rankings in the top 50 percent and bottom 50 percent relate to rankings on international tests for the countries that participated in each test. The study found that the relationship between ranks on international tests of mathematics and science and future economic strength is stronger among nations with lower-performing economies. Nations with strong economies, such as the United States, demonstrate a weaker, nonsignificant relationship.

Economic performance and public concerns about social class in twentieth-century books.

Chen, Yunsong; Yan, Fei

2016-09-01

What is the association between macroeconomic conditions and public perceptions of social class? Applying a novel approach based on the Google Books N-gram corpus, this study addresses the relationship between public concerns about social class and economic conditions throughout the twentieth century. The usage of class-related words/phrases, or "literary references to class," in American English-language books is related to US economic performance and income inequality. The findings of this study demonstrate that economic conditions play a significant role in literary references to class throughout the century, whereas income inequality does not. Similar results are obtained from further analyses using alternative measures of class concerns as well as different corpora of English Fiction and the New York Times. We add to the social class literature by showing that the long-term temporal dynamics of an economy can be exhibited by aggregate class concerns. The application of massive culture-wide content analysis using data of unprecedented size also represents a contribution to the literature. Copyright © 2016 Elsevier Inc. All rights reserved.

Finding ecologically and economically effective ways to establish matrix species is often critical for restoration success. Wyoming big sagebrush (Artemisia tridentata subsp. wyomingensis) historically dominated large areas of western North America, but has been extirpated from many areas by large wildfires; its re-establishment in these areas often requires active management. We evaluated the performance (survival, health) and economic costs of container and bare-root stock based on operational plantings of more than 1.5 million seedlings across 2 200 ha, and compared our plantings with 30 other plantings in which sagebrush survival was tracked for up to 5 yr. Plantings occurred between 2001 and 2007, and included 12 combinations of stock type, planting amendment, and planting year.We monitored 10 500 plants for up to 8 yr after planting. Survival to Year 3 averaged 21% and was higher for container stock (30%) than bare-root stock (17%). Survival did not differ among container stock plantings, whereas survival of bare-root stock was sometimes enhanced by a hydrogel dip before planting, but not by

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

Gains by women reversed in economic downturn.

Science.gov (United States)

1999-01-01

The impact of globalization on women was discussed by the Women in Development Section of the Social Development Division of the UN Economic and Social Commission for Asia and the Pacific (ESCAP). Feminization of work in much of the Asian region occurred in the context of overall economic growth in the 1980s and the first half of the 1990s. However, the recent economic crisis has led to a downturn in the positive aspects of this change in women's position, although gender gaps will be reduced through the worsening conditions of male workers. The current deflationary adjustment policies of reducing government expenditures will adversely affect women in the workplace and the household. Since women have been forced to earn additional income outside the home, the girl-children are expected to perform household and child care duties that would otherwise be performed by their mothers. Incidence of child labor and dropout rates among girls has increased. Many social and cultural norms also allow cuts in the food supply for women and girl-children when household per-capita access to food declines. These circumstances invite domestic violence against women. Hence, institutions such as ESCAP should assume a more active advocacy role with the governments as they confront the economic crisis and its repercussions.

How Does Social Trust Affect Economic Growth?

DEFF Research Database (Denmark)

Bjørnskov, Christian

This paper connects two strands of the literature on social trust by estimating the effects of trust on growth through a set of potential transmission mechanisms directly. It does so by modelling the process using a three-stage least squares estimator on a sample of countries for which a full data...... set is available. The results indicate that trust affects schooling and the rule of law directly. These variables in turn affect the investment rate (schooling) and provide a direct effect (rule of law) on the growth rate. The paper closes with a short discussion of the relevance of the findings....

Error framing effects on performance: cognitive, motivational, and affective pathways.

Science.gov (United States)

Steele-Johnson, Debra; Kalinoski, Zachary T

2014-01-01

Our purpose was to examine whether positive error framing, that is, making errors salient and cuing individuals to see errors as useful, can benefit learning when task exploration is constrained. Recent research has demonstrated the benefits of a newer approach to training, that is, error management training, that includes the opportunity to actively explore the task and framing errors as beneficial to learning complex tasks (Keith & Frese, 2008). Other research has highlighted the important role of errors in on-the-job learning in complex domains (Hutchins, 1995). Participants (N = 168) from a large undergraduate university performed a class scheduling task. Results provided support for a hypothesized path model in which error framing influenced cognitive, motivational, and affective factors which in turn differentially affected performance quantity and quality. Within this model, error framing had significant direct effects on metacognition and self-efficacy. Our results suggest that positive error framing can have beneficial effects even when tasks cannot be structured to support extensive exploration. Whereas future research can expand our understanding of error framing effects on outcomes, results from the current study suggest that positive error framing can facilitate learning from errors in real-time performance of tasks.

Enokidani, Masafumi; Kawai, Kazuhiro; Shinozuka, Yasunori; Watanabe, Aiko

2017-08-01

Milking performance of milking machines that matches the production capability of dairy cows is important in reducing the risk of mastitis, particularly in high-producing cows. This study used a simulated milking device to examine the milking performance of the milking system of 73 dairy farms and to analyze the factors affecting claw vacuum. Mean claw vacuum and range of fluctuation of claw vacuum (claw vacuum range) were measured at three different flow rates: 5.7, 7.6 and 8.7 kg/min. At the highest flow rate, only 16 farms (21.9%) met both standards of mean claw vacuum ≥35 kPa and claw vacuum range ≤ 7 kPa, showing that milking systems currently have poor milking performance. The factors affecting mean claw vacuum were claw type, milk-meter and vacuum shut-off device; the factor affecting claw vacuum range was claw type. Examination of the milking performance of the milking system using a simulated milking device allows an examination of the performance that can cope with high producing cows, indicating the possibility of reducing the risk of mastitis caused by inappropriate claw vacuum. © 2016 Japanese Society of Animal Science.

Can motto-goals outperform learning and performance goals? Influence of goal setting on performance and affect in a complex problem solving task

Directory of Open Access Journals (Sweden)

Miriam S. Rohe

2016-09-01

Full Text Available In this paper, we bring together research on complex problem solving with that on motivational psychology about goal setting. Complex problems require motivational effort because of their inherent difficulties. Goal Setting Theory has shown with simple tasks that high, specific performance goals lead to better performance outcome than do-your-best goals. However, in complex tasks, learning goals have proven more effective than performance goals. Based on the Zurich Resource Model (Storch & Krause, 2014, so-called motto-goals (e.g., "I breathe happiness" should activate a person’s resources through positive affect. It was found that motto-goals are effective with unpleasant duties. Therefore, we tested the hypothesis that motto-goals outperform learning and performance goals in the case of complex problems. A total of N = 123 subjects participated in the experiment. In dependence of their goal condition, subjects developed a personal motto, learning, or performance goal. This goal was adapted for the computer-simulated complex scenario Tailorshop, where subjects worked as managers in a small fictional company. Other than expected, there was no main effect of goal condition for the management performance. As hypothesized, motto goals led to higher positive and lower negative affect than the other two goal types. Even though positive affect decreased and negative affect increased in all three groups during Tailorshop completion, participants with motto goals reported the lowest rates of negative affect over time. Exploratory analyses investigated the role of affect in complex problem solving via mediational analyses and the influence of goal type on perceived goal attainment.

System performance and economic analysis of solar-assisted cooling/heating system

KAUST Repository

Huang, B.J.

2011-11-01

The long-term system simulation and economic analysis of solar-assisted cooling/heating system (SACH-2) was carried out in order to find an economical design. The solar heat driven ejector cooling system (ECS) is used to provide part of the cooling load to reduce the energy consumption of the air conditioner installed as the base-load cooler. A standard SACH-2 system for cooling load 3.5. kW (1. RT) and daily cooling time 10 h is used for case study. The cooling performance is assumed only in summer seasons from May to October. In winter season from November to April, only heat is supplied. Two installation locations (Taipei and Tainan) were examined.It was found from the cooling performance simulation that in order to save 50% energy of the air conditioner, the required solar collector area is 40m2 in Taipei and 31m2 in Tainan, for COPj=0.2. If the solar collector area is designed as 20m2, the solar ejector cooling system will supply about 17-26% cooling load in Taipei in summer season and about 21-27% cooling load in Tainan. Simulation for long-term performance including cooling in summer (May-October) and hot water supply in winter (November-April) was carried out to determine the monthly-average energy savings. The corresponding daily hot water supply (with 40°C temperature rise of water) for 20m2 solar collector area is 616-858L/day in Tainan and 304-533L/day in Taipei.The economic analysis shows that the payback time of SACH-2 decreases with increasing cooling capacity. The payback time is 4.8. years in Tainan and 6.2. years in Taipei when the cooling capacity >10. RT. If the ECS is treated as an additional device used as a protective equipment to avoid overheating of solar collectors and to convert the excess solar heat in summer into cooling to reduce the energy consumption of air conditioner, the payback time is less than 3 years for cooling capacity larger than 3.

Capturing data from employee-supervisor dyads (N = 321) from eight organizations in Pakistan, including human service organizations, an electronics assembly plant, a packaging material manufacturing company, and a small food processing plant, we used moderated regression analysis to examine whether the relationships between trait affect (positive affectivity [PA] and negative affectivity [NA]) and two key work outcome variables (job performance and turnover) are contingent upon the level of job satisfaction. We applied the Trait Activation Theory to explain the moderating effect of job satisfaction on the relationship between affect and performance and between affect and turnover. Overall, the data supported our hypotheses. Positive and negative affectivity influenced performance and the intention to quit, and job satisfaction moderated these relationships. We discuss in detail the results of these findings and their implications for research and practice.

Economic analysis of coal-based polygeneration system for methanol and power production

International Nuclear Information System (INIS)

Lin, Hu; Jin, Hongguang; Gao, Lin; Han, Wei

Polygeneration system for chemical and power co-production has been regarded as one of promising technologies to use fossil fuel more efficiently and cleanly. In this paper the thermodynamic and economic performances of three types of coal-based polygeneration system were investigated and the influence of energy saving of oxygenation systems on system economic performance was revealed. The primary cost saving ratio (PCS) is presented as a criterion, which represents the cost saving of polygeneration system compared with the single-product systems with the same products outputs, to evaluate economic advantages of polygeneration system. As a result, the system, adopting un-reacted syngas partly recycled to the methanol synthesis reactor and without the shift process, can get the optimal PCS of 11.8%, which results from the trade-off between the installed capital cost saving and the energy saving effects on the cost saving, and represents the optimal coupling relationship among chemical conversion, energy utilization and economic performance. And both of fuel price and the level of equipment capital cost affect on PCS faintly. This paper provides an evaluation method for polygeneration systems based on both technical and economic viewpoints. (author)

Khan, Syed Abdul Rehman; Qianli, Dong

2017-12-01

The aim of this study is to examine the association between national economic and environmental indicators with green logistics performance in a time series data of UK since 1981 to 2016. The research used autoregressive distributed lag method to understand the long-run and short-run relationships of national scale economic (foreign direct investment (FDI) inflows, per capita income) and environmental indicators (total greenhouse gases, fossil fuel, and renewable energy) on green logistics. In the short run, the research findings indicate that the green logistics and renewable energy have positive relationship, while fossil fuel is negatively correlated with green logistics operations. On the other hand, in the long run, the results show that FDI inflows, renewable energy sources, and per capita income have statistically significant and positive association with green logistics activities, while foreign investments attracted by environmental friendly policies and practices adopted in global logistics operations, which not only increase the environmental sustainability but also enhance economic activities with greater export opportunities in the region.

High-performance workplace practices in nursing homes: an economic perspective.

Science.gov (United States)

Bishop, Christine E

2014-02-01

To develop implications for research, practice and policy, selected economics and human resources management research literature was reviewed to compare and contrast nursing home culture change work practices with high-performance human resource management systems in other industries. The organization of nursing home work under culture change has much in common with high-performance work systems, which are characterized by increased autonomy for front-line workers, self-managed teams, flattened supervisory hierarchy, and the aspiration that workers use specific knowledge gained on the job to enhance quality and customization. However, successful high-performance work systems also entail intensive recruitment, screening, and on-going training of workers, and compensation that supports selective hiring and worker commitment; these features are not usual in the nursing home sector. Thus despite many parallels with high-performance work systems, culture change work systems are missing essential elements: those that require higher compensation. If purchasers, including public payers, were willing to pay for customized, resident-centered care, productivity gains could be shared with workers, and the nursing home sector could move from a low-road to a high-road employment system.

Socio-cultural and economic factors affecting food consumption patterns in the Arab countries.

Science.gov (United States)

Musaiger, A O

1993-04-01

Several factors have been found to determine the dietary habits of the people in the Arab world. Food consumption pattern has dramatically changed in some Arab countries as a result of sudden increase in income from oil revenue. It is believed that food subsidy policy has adversely affected the food habits in the Gulf states by encouraging the intake of fat, sugar, rice, wheat flour and meat. Socio-cultural factors such as religion, beliefs, food preferences, gender discrimination, education and women's employment all have a noticeable influence on food consumption patterns in this region. Mass media, especially televised food advertisements, play an important role in modifying the dietary habits. The migration movement, particularly that which was carried out during the 70s has a great impact on the food practices in many Arab countries. Comprehensive studies on social, cultural and economic factors associated with food consumption patterns in the Arab region are highly recommended.

Lavinia Flueckiger

Full Text Available OBJECTIVE: This intensive longitudinal study examined how sleep and physical activity relate to university students' affect and academic performance during a stressful examination period. METHODS: On 32 consecutive days, 72 first-year students answered online questionnaires on their sleep quality, physical activity, positive and negative affect, learning goal achievement, and examination grades. First-year university students are particularly well-suited to test our hypotheses: They represent a relatively homogeneous population in a natural, but controlled setting, and simultaneously deal with similar stressors, such as examinations. Data were analyzed using multilevel structural equation models. RESULTS: Over the examination period, better average sleep quality but not physical activity predicted better learning goal achievement. Better learning goal achievement was associated with increased probability of passing all examinations. Relations of average sleep quality and average physical activity with learning goal achievement were mediated by experienced positive affect. In terms of day-to-day dynamics, on days with better sleep quality, participants reported better learning goal achievement. Day-to-day physical activity was not related to daily learning goal achievement. Daily positive and negative affect both mediated the effect of day-to-day sleep quality and physical activity on daily learning goal achievement. CONCLUSION: Health behaviors such as sleep quality and physical activity seem important for both academic performance and affect experience, an indicator of mental health, during a stressful examination period. These results are a first step toward a better understanding of between- and within-person variations in health behaviors, affect, and academic performance, and could inform prevention and intervention programs for university students.

Lynn, Spencer K; Zhang, Xuan; Barrett, Lisa Feldman

2012-08-01

Studies of the effect of affect on perception often show consistent directional effects of a person's affective state on perception. Unpleasant emotions have been associated with a "locally focused" style of stimulus evaluation, and positive emotions with a "globally focused" style. Typically, however, studies of affect and perception have not been conducted under the conditions of perceptual uncertainty and behavioral risk inherent to perceptual judgments outside the laboratory. We investigated the influence of perceivers' experienced affect (valence and arousal) on the utility of social threat perception by combining signal detection theory and behavioral economics. We compared 3 perceptual decision environments that systematically differed with respect to factors that underlie uncertainty and risk: the base rate of threat, the costs of incorrect identification threat, and the perceptual similarity of threats and nonthreats. We found that no single affective state yielded the best performance on the threat perception task across the 3 environments. Unpleasant valence promoted calibration of response bias to base rate and costs, high arousal promoted calibration of perceptual sensitivity to perceptual similarity, and low arousal was associated with an optimal adjustment of bias to sensitivity. However, the strength of these associations was conditional upon the difficulty of attaining optimal bias and high sensitivity, such that the effect of the perceiver's affective state on perception differed with the cause and/or level of uncertainty and risk.

Sociopolitical and economic elements to explain the environmental performance of countries.

Almeida, Thiago Alexandre das Neves; García-Sánchez, Isabel-María

2017-01-01

The present research explains environmental performance using an ecological composite index as the dependent variable and focusing on two national dimensions: sociopolitical characteristics and economics. Environmental performance is measured using the Composite Index of Environmental Performance (CIEP) indicator proposed by García-Sánchez et al. (2015). The first model performs a factor analysis to aggregate the variables according to each analyzed dimension. In the second model, the estimation is run using only single variables. Both models are estimated using generalized least square estimation (GLS) using panel data from 152 countries and 6 years. The results show that sociopolitical factors and international trade have a positive effect on environmental performance. When the variables are separately analyzed, democracy and social policy have a positive effect on environmental performance while transport, infrastructure, consumption of goods, and tourism have a negative effect. Further observation is that the trade-off between importing and exporting countries overshadows the pollution caused by production. It was also observed that infrastructure has a negative coefficient for developing countries and positive for developed countries. The best performances are in the democratic and richer countries that are located in Europe, while the worst environmental performance is by the nondemocratic and the poorest countries, which are on the African continent.

Full Text Available This study examines the relationship between public expenditure within regional autonomy policy and economic growth in West Papua and Papua provinces. We distinguish two kinds of expenditure’s decentralization – operational and capital – and also private expenditures. We use an unbalanced panel data over the period of 2007-2010 to investigate those expenditures, whether they enhance regional economic growth or not. We find that the government’s operating and private expenditures have a positive effect on local economic growth, but there is no relationship between capital expenditure’s decentralization on economic growth. The findings did not conform to a-priori efficiency expectations, which suggest needing to reform regional autonomy and fiscal decentralization policy in both provinces.

Performance of laying hens and economic viability of different climatization systems

Gabriela F. Silva

2013-06-01

Full Text Available Since thermal environment affects production, egg quality and laying hens’ mortality rates, it is highly relevant to control the thermal environment within poultry houses so that the best financial profits could be obtained. Three commercial poultry houses with different climatization systems are analyzed in current research: a poultry house with tunnel-like ventilation and pad cooling; a poultry house with natural ventilation and nebulization; a poultry house with simple natural ventilation. Their thermal environment, production, egg quality and laying hens’ mortality rates among different poultry houses and at different areas of the same poultry house are compared. Economic profits based on difference in electric energy consumption by climatization systems and on the laying hens’ productivity of each poultry house are calculated. Electricity meters were installed within the electrical circuits of the climatization and light systems of the three poultry houses. Data were registered between December 2011 and March 2012 and results showed that all the poultry houses featured heterogeneity in internal thermal environment with faults in the climatization systems. Important differences were reported in egg production and quality caused by overheating. The poultry house with tunnel-like ventilation and pad cooling had the best thermal isolation from the external environment that resulted in a 12.04% improvement in production, decrease between 30 and 40% in laying hens’ mortality rates and the best economic result.

believe that structural change is an unimportant side effect of the economic development. On the contrary, economists associated with the World Bank and some others posit that growth is brought about by the changes in sectoral composition. The objective of this study is to empirically test...... the relationship between sectoral shares and economic growth by using the panel data for 20 developed countries. The results of the granger causality suggest that both services and agriculture sectors do granger cause economic growth, whereas industrial sector does not granger cause growth. Reverse causality does...... not hold for any of the three sectors. The results of Barro and Non-Barro regressions along with the set of control variables have suggested that services sector is negatively affecting growth, whereas both industrial and agriculture shares are positively affect economic growth....

Rummel, Jan; Kuhlmann, Beatrice G; Touron, Dayna R

2013-09-01

To investigate whether making performance predictions affects prospective memory (PM) processing, we asked one group of participants to predict their performance in a PM task embedded in an ongoing task and compared their performance with a control group that made no predictions. A third group gave not only PM predictions but also ongoing-task predictions. Exclusive PM predictions resulted in slower ongoing-task responding both in a nonfocal (Experiment 1) and in a focal (Experiment 2) PM task. Only in the nonfocal task was the additional slowing accompanied by improved PM performance. Even in the nonfocal task, however, was the correlation between ongoing-task speed and PM performance reduced after predictions, suggesting that the slowing was not completely functional for PM. Prediction-induced changes could be avoided by asking participants to additionally predict their performance in the ongoing task. In sum, the present findings substantiate a role of metamemory for attention-allocation strategies of PM. Copyright © 2013 Elsevier Inc. All rights reserved.

On the assumption of the commercialization stage of technologies, the analysis on performances in financial operation based on simulation studies is one of important study subjects in the field of the system analysis and economic assessments of nuclear technologies. However, economic assessments on financial performances of such complex industries as nuclear power based on nuclear fuel cycle industries, or as electric utilities composed of hydro, fossil, nuclear power stations are complicated, and the adoption of conventional financial model is insufficient in the case of nuclear technologies which have such special financial process as decommissioning. We, therefore, develop the computer simulation model that can analyze financial performances of nuclear facilities. In this report, the derivation of equations and outlines of the model are explained. Additionally, examples of hypothetical financial simulation studies on a coal-gasoline plant, nuclear waste industries, and analysis on economic perspectives of small size nuclear reactors for electric utilities are indicated.

Full Text Available Performance measurement systems are an extremely important part of the control and management actions, because in this way a company can determine its business potential, its market power, potential and current level of business efficiency. The significance of measurement consists in influencing the relationship between the results of reproduction (total volume of production, value of production, total revenue and profit and investments to achieve these results (factors of production spending and hiring capital in order to achieve the highest possible quality of the economy. (The relationship between the results of reproduction and investment to achieve them quantitatively determines economic success as the quality of the economy. Measuring performance allows the identification of the economic resources the company has, so looking at the key factors that affect its performance can help to determine the appropriate course of action.

Field-to-Fuel Performance Testing of Lignocellulosic Feedstocks for Fast Pyrolysis and Upgrading: Techno-economic Analysis and Greenhouse Gas Life Cycle Analysis

Energy Technology Data Exchange (ETDEWEB)

Meyer, Pimphan A.; Snowden-Swan, Lesley J.; Rappé, Kenneth G.; Jones, Susanne B.; Westover, Tyler L.; Cafferty, Kara G.

2016-11-17

This work shows preliminary results from techno-economic analysis and life cycle greenhouse gas analysis of the conversion of seven (7) biomass feedstocks to produce liquid transportation fuels via fast pyrolysis and upgrading via hydrodeoxygenation. The biomass consists of five (5) pure feeds (pine, tulip poplar, hybrid poplar, switchgrass, corn stover) and two blends. Blend 1 consists of equal weights of pine, tulip poplar and switchgrass, and blend 2 is 67% pine and 33% hybrid poplar. Upgraded oil product yield is one of the most significant parameters affecting the process economics, and is a function of both fast pyrolysis oil yield and hydrotreating oil yield. Pure pine produced the highest overall yield, while switchgrass produced the lowest. Interestingly, herbaceous materials blended with woody biomass performed nearly as well as pure woody feedstock, suggesting a non-trivial relationship between feedstock attributes and production yield. Production costs are also highly dependent upon hydrotreating catalyst-related costs. The catalysts contribute an average of ~15% to the total fuel cost, which can be reduced through research and development focused on achieving performance at increased space velocity (e.g., reduced catalyst loading) and prolonging catalyst lifetime. Green-house-gas reduction does not necessarily align with favorable economics. From the greenhouse gas analysis, processing tulip poplar achieves the largest GHG emission reduction relative to petroleum (~70%) because of its lower hydrogen consumption in the upgrading stage that results in a lower natural gas requirement for hydrogen production. Conversely, processing blend 1 results in the smallest GHG emission reduction from petroleum (~58%) because of high natural gas demand for hydrogen production.

As of the end of Dec. 1999, Korea's total nuclear power capacity reached 13,716 MWe with 16 units in operation and 4 units under construction. In addition, as part of the national long-term R and D programme launched in 1992, the Korean Next Generation Reactor (KNGR) is being developed to meet the electricity demands in the years to come and is expected to be safer and more economically competitive than any other conventional electric power sources in Korea. The KNGR project has successfully completed its second phase and is now on the third phase. In Phase III of the KNGR design development project, KNGR aims at reinforcing the economic competitiveness while maintaining safety goals. To achieve these objectives, the design options studied and the design requirements set up in the first phase are pursued while the second phase are being reviewed. This paper summarizes such efforts for design improvement in terms of performance and economic viability along with the status of nuclear power generation in Korea, focusing on KNGR currently.

A proposal of ecologic taxes based on thermo-economic performance of heat engine models

International Nuclear Information System (INIS)

Barranco-Jimenez, M. A.; Ramos-Gayosso, I.; Rosales, M. A.; Angulo-Brown, F.

2009-01-01

Within the context of Finite-Time Thermodynamics (FTT) a simplified thermal power plant model (the so-called Novikov engine) is analyzed under economical criteria by means of the concepts of profit function and the costs involved in the performance of the power plant. In this study, two different heat transfer laws are used, the so called Newton's law of cooling and the Dulong-Petit's law of cooling. Two FTT optimization criteria for the performance analysis are used: the maximum power regime (MP) and the so-called ecological criterion. This last criterion leads the engine model towards a mode of performance that appreciably diminishes the engine's wasted energy. In this work, it is shown that the energy-unit price produced under maximum power conditions is cheaper than that produced under maximum ecological (ME) conditions. This was accomplished by using a typical definition of profits function stemming from economics. The MP-regime produces considerably more wasted energy toward the environment, thus the MP energy-unit price is subsidized by nature. Due to this fact, an ecological tax is proposed, which could be a certain function of the price difference between the MP and ME modes of power production. (author)

Does Question Structure Affect Exam Performance in the Geosciences?

Day, E. A.; D'Arcy, M. K.; Craig, L.; Streule, M. J.; Passmore, E.; Irving, J. C. E.

2015-12-01

The jump to university level exams can be challenging for some students, often resulting in poor marks, which may be detrimental to their confidence and ultimately affect their overall degree class. Previous studies have found that question structure can have a strong impact on the performance of students in college level exams (see Gibson et al., 2015, for a discussion of its impact on physics undergraduates). Here, we investigate the effect of question structure on the exam results of geology and geophysics undergraduate students. Specifically, we analyse the performance of students in questions that have a 'scaffolded' framework and compare them to their performance in open-ended questions and coursework. We also investigate if observed differences in exam performance are correlated with the educational background and gender of students, amongst other factors. It is important for all students to be able to access their degree courses, no matter what their backgrounds may be. Broadening participation in the geosciences relies on removing systematic barriers to achievement. Therefore we recommend that exams are either structured with scaffolding in questions at lower levels, or students are explicitly prepared for this transition. We also recommend that longitudinal studies of exam performance are conducted within individual departments, and this work outlines one approach to analysing performance data.

Lusk, J L

2017-06-01

This paper elucidates the challenges surrounding the economics of some popular obesity-related policy proposals. Solid economic justifications for anti-obesity policies are often lacking, and evidence suggests policies like fat and soda taxes or restrictions on food stamp spending are unlikely to substantively affect obesity prevalence. In short, many of the same factors that make obesity such a complicated and multifaceted issue extend to the economic analysis of public health policies.

Full Text Available State level economy has always been relying on its major metropolitan area’s economic success. So, such metropolitan agglomerations have been considered the only agents that can foster the state’s economic standing as if other economic places do (or may not have significant contribution to the regional economy. In contrast, as some major cities enhance their economic well-being and agglomerate in specialized sector, the rest of the region lose their economic grounds or stay constant by widening the economic gap among cities. Therefore, an institutional approach can help to establish new regional arrangements to substitute all economic places to coordinate each other and succeed the economic growth as part of state government by reducing the disparities. In this sense, this study builds upon the inquiry that seeks the impacts of some economic disparities among economic places (counties on the performances of state level regional economy.

Full Text Available The most common international standards for the non-financial reporting are reviewed. The Global Reporting Initiative (GRI is determined as an optimal standard of sustainability reporting for the use in the Russian conditions. The environmental component of guidance on the compilation of G4 non-financial reporting of GRI standard is analyzed, the contribution of each aspect in terms of the overall picture of sustainability is determined. The progress of economic science has outlined the importance of incorporating natural components. Moreover, the value of biological resources would be increased through time, and therefore, the economic development of the company cannot be in isolation. To determine the degree of harmony between the economic development and ecological condition of the territory where the company carries out the economic activities, the application of new approaches and methods is necessary. Based on the statistical methods, a correlation model between economic development and environmental performance is developed to identify their relationship on the basis of non-financial reporting. The developed model of correlation can be used by a wide range of oil and gas companies and its general principles by the companies of different industries. The results may be of interest to stakeholders, also, it can be used for administrative purposes, to serve as a platform for forecasting and adoption of administrative decisions to achieve harmony between economic development and environmental performance. The model of correlation has been tested for the data of non-financial reporting of the Russian largest oil and gas company JSC “Surgutneftegas”. The testing has shown a positive relationship between the two systems of the company’s sustainable development: economy and ecology. This obtained result demonstrates a high level of social responsibility of the company in terms of environmental protection. A further study in this field can

In this paper, we focus on the connections between creativity, social capital and economic performance and growth. Our working hypothesis is that both creativity and social capital influences the economy, both each per se, but also through their influence on each other. We regard creativity as one of the sources of entrepreneurship and innovation (although creativity also can have ‘bad’ consequences if bad actors such as criminals perform it). Depending on the types of networks and the norms ...

To investigate the association between touch sensation of the affected hand and performance and satisfaction with performance of valued activities in individuals with chronic stroke. Using a cross-sectional study design, this study correlated factors related to hand sensation and activity performance in individuals with chronic stroke. The Touch Test Evaluators and Canadian Occupational Performance Measure (COPM) were used. Correlations were used to determine the relationships between touch sensation of the affected hand and individuals' performance and satisfaction with performance of valued activities. There was a good to excellent relationship between sensation and performance and satisfaction with performance of valued activities for individuals with intact touch sensation of the affected hand who scored higher on the COPM. There was little to no relationship between touch sensation of the affected hand and performance of valued activities for individuals with impaired sensation. This is the first study to relate touch sensation of the affected hand and performance and satisfaction with performance of valued activities in individuals with stroke. The findings suggest that rehabilitation therapists need to continue to address sensory function in evaluation and intervention as it relates to performance in valued activities. This study serves as a foundation for future research in sensation and performance of valued activities in individuals with chronic stroke.

Constriction is a prey-immobilization technique used by many snakes and is hypothesized to have been important to the evolution and diversification of snakes. However, very few studies have examined the factors that affect constriction performance. We investigated constriction performance in ball pythons (Python regius) by evaluating how peak constriction pressure is affected by snake size, sex, and experience. In one experiment, we tested the ontogenetic scaling of constriction performance and found that snake diameter was the only significant factor determining peak constriction pressure. The number of loops applied in a coil and its interaction with snake diameter did not significantly affect constriction performance. Constriction performance in ball pythons scaled differently than in other snakes that have been studied, and medium to large ball pythons are capable of exerting significantly higher pressures than those shown to cause circulatory arrest in prey. In a second experiment, we tested the effects of experience on constriction performance in hatchling ball pythons over 10 feeding events. By allowing snakes in one test group to gain constriction experience, and manually feeding snakes under sedation in another test group, we showed that experience did not affect constriction performance. During their final (10th) feedings, all pythons constricted similarly and with sufficiently high pressures to kill prey rapidly. At the end of the 10 feeding trials, snakes that were allowed to constrict were significantly smaller than their non-constricting counterparts. © 2016 Wiley Periodicals, Inc.

Economic institutions and economic growth: Empirical evidence from the Economic Community of West African States

Lazarus Z. Wanjuu

2017-12-01

Background: Economic institutions are considered as the fundamental cause of economic growth. Economic institutions affect economic growth through allocation of resources like physical and human capital. Unfortunately, there is dearth of empirical studies showing the impact of economic institutions on growth of the Economic Community of West African States (ECOWAS. Aim: This study investigates the impact of economic institutions on economic growth of the ECOWAS. Setting and method: The study applied cause and effect relationship. The study used econometric research techniques of unit root and co-integration tests to establish the time series properties of the data; the vector error correction and co-integration regression models to estimate the population parameters. The research data comprised data obtained from the United Nations Conference on Trade and Development (UNCTAD, the Transparency International (TI and Heritage Foundation databases. The variables employed were the real gross domestic product (GDP per capita (RGDPPC, corruption perception index (CPI, property rights protection (PROPRGT, private investment per capita (INVESPC, government expenditure per capita (GOEXPPC and trade openness (TRAOPN. Results: The results of the data analysed showed that economic institutions represented by the property rights index engender RGDPPC growth in ECOWAS. The CPI could not stimulate RGDPPC growth in ECOWAS. The results also show that all the other variables stimulated growth except trade openness. Conclusion: The study concludes that good economic institutions, private investments, and government intervention by providing security, economic and social infrastructural facilities are conducive for economic growth in the ECOWAS region. The study recommended that more efforts be made at curbing corruption in the region

THE ECONOMIC FARM SIZE AND SUSTAINABLE VALUE DISPARITIES BETWEEN ROMANIA AND THE EU STATES

Full Text Available Romania is one of the EU countries with significant agricultural potential. The economic and social changes occurring after 1990 has profoundly affected the agriculture in Romania. The excessive land fragmentation due to land restitution to the former owners and their heirs, as well as the subsequent developments have led to a large number of small-sized agricultural holdings and a small number of large agricultural holdings, in terms of size and economy. The sustainability performance must be assessed from the economic, social and environmental points of view. The paper aims to assess the sustainable performance of the agricultural holdings in Romania on economic size classes, to highlight the directions for enhancing the performance by reorganizing the agricultural structures. For achieving this purpose, we used the Sustainable Value-based approach. The results of comparison between Romania and other EU countries highlight the importance of medium-sized farms, which achieve the best performance expressed by the Sustainable Value.

How economic growth affects emissions? An investigation of the environmental Kuznets curve in Portuguese and Spanish economic activity sectors

International Nuclear Information System (INIS)

Moutinho, Victor; Varum, Celeste; Madaleno, Mara

2017-01-01

It is a disquieting reality that increased economic growth for many years now in the Western world is at odds with environmental degradation. In this paper the relationship between economic growth and environmental variables is analyzed under two non-linear specifications, a quadratic and a cubic specification. The study is conducted for Portugal and Spain in the period 1975–2012, using data for 13 sectors. GVA is used as proxy for income, while energy use and carbon dioxide account for environmental degradation. There is evidence for an inverted U-shaped EKC. However, there are also other inverted N–shaped functions that explain the relationship between economic growth and emissions. Altogether, empirical results do indicate particular differences between Portuguese and Spanish sectors. The results are of interest not only for researchers but also for policy-makers. Political mitigation measures are also analyzed. - Highlights: • We study the EKC hypothesis using economic activity sectors in the Iberian Market. • There is evidence for a clear N-shaped EKC in Portugal. • Inverted N–shaped function explains the economic growth and emissions relationship. • Positive and significant effect of energy consumption in emissions for sectors. • Promote renewables substitution and tax benefits are urgent to accomplish goals.

Uterine inflammation affects the reproductive performance of dairy cows: A review

Directory of Open Access Journals (Sweden)

Roger Eduardo Molina-Coto

2018-05-01

Full Text Available Incidence of post- partum uterine disease is an important concern in dairy cattle, because it affects its reproduction. Therefore, the objective of this review of literature was to generate a multifactorial overview about uterine diseases, and the reproductive performance of dairy cows, from a zootechnical approach. Dairy cows face multiple challenges around parturition. Immune suppression around calving, exposition to trauma and uterine bacterial contamination, metabolic diseases, lactation, and changes in management make dairy cows susceptible to uterine diseases. Most cows are able to eliminate uterine infection after calving, however, some cows keep uterine disease. Uterine disease may show clinical signs, but also silent signs that affect fertility as well. Poor reproductive performance is not caused by those signs by themselves, but due to alterations in ovarian and uterine function. Also, the problem of this silent signs is that farmers become aware of the disease when it has already caused negative effects on the reproductiveperformance. Sometimes, uterine disease is still present at the moment of the first service after calving. Uterine diseasemake it harder for cows to get pregnant because it affects the establishment and maintenance of pregnancy, being another cause for infertility, increasing the cull rate and decreasing incomes from the dairy industry.

Performance analysis of supply and return fans for HVAC systems under different operating strategies of economizer dampers

HVAC systems and associated equipment consume a relatively large fraction of total building energy consumption, a significant portion of which is attributed to fan operation. The operation of economizer dampers when installed can cause high energy consumption in fans if they are not functioning in proper and optimal manner. This will mainly be due to the potential high pressure drops through those dampers and associated high total pressures that should be developed by supply and/or return fans. It is then necessary to ensure that a proper strategy to operate optimally the economizer dampers is implemented with minimum fan energy use. The paper examines several operation strategies of the economizer dampers and investigates their effects on the performance of both the supply and return fans in HVAC system. It also discusses a new operating strategy for economizer dampers that can lead to lower fan energy use. The strategies are evaluated by simulations for a typically existing HVAC system. Several factors such as the building locations, system characteristics, resistance in the duct where the dampers are installed, supply air temperature and economizer control, and minimum ventilation requirements are also considered during the evaluations. The results show that the way of the economizer dampers been controlled has a significant effect on fan performance and its energy use. The proposed strategy if properly implemented can provide fan energy saving in the range of 5-30%, depending mainly on the number of hours when the system operates in the free cooling mode, damper characteristics, and minimum outdoor air.

2009-01-01

The effect of heat affected zone in high performance steel on fatigue crack propagation behavior, which is related to the subsequent microstructure, was investigated. A modified Paris-Erdogan equation was presented for the analysis of fatigue crack propagation behavior corresponding to the heat affected zone conditions. Fatigue crack propagation tests under 0.3 stress ratio and 0.1 load frequency were conducted for both finegrained and coarse-grained heat affected zones, respectively. As shown in the results, much higher crack growth rate occurred in a relatively larger mean grain size material under the same stress intensity range of fatigue crack propagation process for the material.

Kim, Ju-Young; Jeon, Gyu-Yeob; Hong, Won-Hwa

2009-01-01

The distribution of the photovoltaic systems is faced with technological and economic problems, and the businesses and corporations feel burdened by the photovoltaic system's dubious economic value and high construction costs. Thus, not too many enterprises or private citizens have been participating in the business of installing photovoltaic systems. Moreover, because of lack of skills in integrating engineering and architectural design, they are experiencing difficulties even in using the technologies that have already been developed and available for application. To provide the basic information and specific data required for making the guidelines for developing photovoltaic technologies, this paper evaluates the system types, the actual state of operation, and performance of the two photovoltaic systems that are installed in Kiemyung University's Osan Building and Dongho Elementary School in Daegu Metropolitan City

After formulating a theoretical model, results are reported from an empirical analysis of the European paper manufacturing industry. New data are used to test hypotheses derived from the theoretical model, using environmental performance indices representing different corporate environmental strategy orientations. In particular, an emissions-based index largely reflecting end-of-pipe strategies and an inputs-based index reflecting integrated pollution prevention are distinguished. For the emissions-based index, a predominantly negative relationship between environmental and economic performance is found, whereas for the inputs-based index no significant link is found. This is consistent with the theoretical model, which predicts the possibility of different relationships. The results also show that for firms with pollution prevention-oriented corporate environmental strategies, the relationship between environmental and economic performance is more positive, thus making improvements in corporate sustainability more likely. Based on this last insight, managerial implications of this are discussed with regard to strategy choices, investment decisions and operations management.

Economic integration and cross-border economic organizations: The case of San Diego-Tijuana

Full Text Available The economic integration between the United States and Mexico has affected the economic, political and social relations in the border region. The paper seeks to relate the increasing economic integration and business cycles of the economies of San Diego and Tijuana to the development of both national and binational economic organizations in the border region. The methodology of analysis uses both statistical estimations of the economic integration of San Diego and Tijuana and semi-structured interviews of economic organizations to analyze the increasing economic integration and the role and achievements of the cross-border economic organizations. The results showed that cross-border cooperation is predominately controlled by federal and state governments on both sides of the border. However, the main achievements of cross-border economic cooperation have been accomplished by local private organizations. The perspective of further local economic development greatly depends on both the possibility of increased involvement of federal governments and the growing encouragement of regional organizations.

Generality in nanotechnologies and its relationship to economic performance

Gomez Baquero, Fernando

In the history if economic analysis there is perhaps no more important question than the one of how economic development is achieved. For more than a century, economists have explored the role of technology in economic growth but there is still much to be learned about the effect that technologies, in particular emerging ones, have on economic growth and productivity. The objective of this research is to understand the relationship between nanotechnologies and economic growth and productivity, using the theory of General Purpose Technology (GPT)-driven economic growth. To do so, the Generality Index (calculated from patent data) was used to understand the relative pervasiveness of nanotechnologies. The analysis of trends and patterns of Generality Index, using the largest group of patents since the publication of the NBER Patent Database, indicates that nanotechnologies possess a higher average Generality than other technological groups. Next, the relationship between the Generality Index and Total Factor Productivity (TFP) was studied using econometric analysis. Model estimates indicate that the variation in Generality for the group of nanotechnologies can explain a large proportion of the variation in TFP. However, the explanatory power of the entire set of patents (not just nanotechnologies) is larger and corresponds better to the expected theoretical models. Additionally, there is a negative short-run relationship between Generality and TFP, conflicting with part of the theoretical GPT-models. Finally, the relationship between the Generality of nanotechnologies and policy-driven investment events, such as R&D investments and grant awards, was studied using econometric methods. The statistical evidence suggests that NSF awards are related to technologies with higher Generality, while NIH awards and NNI investments are related to a lower average Generality. Overall, results of this research work indicate that the introduction of pervasive technologies into an

This is in contrast to the extensive evidence that such factors affect lobbying practices...... on the basis of political and economic institutional factors. Focusing on business interest representation, we show that economic institutions structure the ‘supply’ of interest organizations by affecting the number of potential constituents, the resources available for lobbying and the geographical level...

Performance and Economic Analysis of Distributed Power Electronics in Photovoltaic Systems

Energy Technology Data Exchange (ETDEWEB)

Deline, C.; Marion, B.; Granata, J.; Gonzalez, S.

2011-01-01

Distributed electronics like micro-inverters and DC-DC converters can help recover mismatch and shading losses in photovoltaic (PV) systems. Under partially shaded conditions, the use of distributed electronics can recover between 15-40% of annual performance loss or more, depending on the system configuration and type of device used. Additional value-added features may also increase the benefit of using per-panel distributed electronics, including increased safety, reduced system design constraints and added monitoring and diagnostics. The economics of these devices will also become more favorable as production volume increases, and integration within the solar panel?s junction box reduces part count and installation time. Some potential liabilities of per-panel devices include increased PV system cost, additional points of failure, and an insertion loss that may or may not offset performance gains under particular mismatch conditions.

The importance of pharmacoeconomics and health economics has been augmented. It has the potential to provide evidence to aid in optimal decision-making in the funding of cost-effective medicines and services in Gulf Cooperation Council countries (G.C.C). To evaluate the quality and quantity of health economic researches published until the end of 2017 in G.C.C. and to identify the factors that affect the quality of studies. Studies were included according to predefined inclusion and exclusion criteria. The quantity was recorded, and the quality was assessed using the Quality of Health Economic Studies (QHES) instrument. Forty-nine studies were included. The mean (SD) quality score of all studies was 57.83 (25.05), and a high number of reviewed studies (47%) were evaluated as either poor or extremely poor quality. The factors that affect the quality of studies with statistical significance were, the type and method of economic evaluation, the economic outcome was the objective of the research, author`s background, the perspective of the study, health intervention and source of funding. The use of economic evaluation studies in G.C.C was limited. Different factors that affect the quality of articles such as performing a full economic evaluation and choosing societal perspective were identified. Strategies to improve the quality of future studies were recommended.

A Proposal of Ecologic Taxes Based on Thermo-Economic Performance of Heat Engine Models

Full Text Available Within the context of Finite-Time Thermodynamics (FTT a simplified thermal power plant model (the so-called Novikov engine is analyzed under economical criteria by means of the concepts of profit function and the costs involved in the performance of the power plant. In this study, two different heat transfer laws are used, the so called Newton’s law of cooling and the Dulong-Petit’s law of cooling. Two FTT optimization criteria for the performance analysis are used: the maximum power regime (MP and the so-called ecological criterion. This last criterion leads the engine model towards a mode of performance that appreciably diminishes the engine’s wasted energy. In this work, it is shown that the energy-unit price produced under maximum power conditions is cheaper than that produced under maximum ecological (ME conditions. This was accomplished by using a typical definition of profits function stemming from economics. The MP-regime produces considerably more wasted energy toward the environment, thus the MP energy-unit price is subsidized by nature. Due to this fact, an ecological tax is proposed, which could be a certain function of the price difference between the MP and ME modes of power production.

A THEORETICAL APPROACH OF THE CONCEPT OF SOCIAL CAPITAL IN SUPPORTING ECONOMIC PERFORMANCE

Directory of Open Access Journals (Sweden)

Boldea Monica

2012-07-01

Full Text Available Any activity requires the presence of labor resources. If centuries ago the concept was that their presence was enough, now it takes a lot more. Moreover, since Aristotle the issue was taking into consideration all aspects of the community life that can lead to a "better life". In the current conditions we may consider resources in the broader context of the human factor and of the relations established within a society. Thus social capital was conceptualized. As opportunities of economic growth - based purely on the quantitative aspects of the determinants – were limited, the need occurred to reconsider the qualitative and structural components. Social capital considers a number of the integrative components of social life. These refer to the relations established at family level up to the level of societal institutions. It is necessary that these relationships be well established, and for the proper performance it is necessary that aspects of education and health should be properly valued and assessed. This helps setting up strong institutions. Developed countries have the ability to create a proper environment for the manifestations of social capital; in these countries one can observe the growing importance of formal and more impersonal relations. But this just reinforces the occurrence and development of economic activities based on efficiency criteria leading to the countries’ economic development. The interpretations of economic development issues have undergone changes in recent decades. If previously it was considered that the essential difference between rich and poor countries is reflected in the amount of physical capital per person, later on the concept of capital has been expanded to include as well human capital, the lack of which was considered a serious obstacle to development, particularly in the case of poor countries. And given the fact that the transactions within an economic system take place in an

Full Text Available This paper presents an overview of previous studies on the environmental impact (EI and toxicity of producing recycled concrete aggregates (RCA, fly ash (FA, cement, superplasticizer, and water as raw materials, and also on the effect of replacing cement and natural aggregates (NA with FA and RCA, respectively, on the mentioned aspects. EI and toxicity were analysed simultaneously because considering concrete with alternative materials as sustainable depends on whether their risk assessment is high. Therefore, this study mainly focuses on the cradle-to-gate EI of one cubic meter of concrete, namely abiotic depletion potential (ADP, global warming potential (GWP, ozone depletion potential (ODP, photochemical ozone creation (POCP, acidification potential (AP, eutrophication potential (EP, non-renewable energy (PE-NRe and renewable energy (PE-Re. In terms of toxicity, leachability (chemical and ecotoxicological characterization was considered. The results also include the economic performance of these materials, and show that the incorporation of FA in concrete significantly decreases the EI and cost of concrete. Thus, the simultaneous incorporation of FA and RCA decrease the EI, cost, use of landfill space and natural resources extraction. Nonetheless, the leaching metals of FA decrease when they are incorporated in concrete. Relative to FA, the incorporation of RCA does not significantly affect the EI and cost of concrete, but it significantly reduces the use of landfill space and the need of virgin materials.

COSTACHE R.

2015-03-01

Full Text Available The present study aims to provide an example of the assessment of economical loss caused by floods and flash-floods, by integrating GIS techniques of hydraulic and hydrological modelling. The case study was performed in Lopătari village, which is located in the upper area of Slănic River, one of the most affected areas by floods and flash-floods. The flood event produced on 29.V.2012 was considered in order to perform this study. Thus, a flood hydrograph was simulated by using software HEC-HMS 3.5, based on hourly precipitation data from Bisoca meteorological station from 29.V.2012. The peak discharge resulting from the hydrological modelling software was used in HEC-RAS 4.1 hydraulic modelling software in order to determine the extent of flooding band, the number of the affected elements and the local economical loss. Finally, 21 flooded buildings were identified and 550 m of affected road, the estimated economical damage being about 800,000 RON.
