    Full Text Available The concept of occupational self-efficacy means the efficacy perceptions of employees in their occupational fields, and the concept of organizational silence means the employees avoid to voice their ideas and suggestions about organizational issues. The main aim of this study is to examine the relationship between the concepts of occupational self-efficacy and organizational silence by revealing employees’ perceptions of occupational self-efficacy and organizational silence level. With this aim, the survey study was conducted on total 114 academicians who work in University of Bayburt. As a result of research, while the significant relationship was found between employees’ perceptions of occupational self-efficacy and organizational silence level, there was reached a result that this relationship incurred the negatively relationship between perceptions of occupational self-efficacy and negative silence.

  2. Determination of the acidification state of Canadian Pacific coastal waters using empirical relationships with hydrographic data

    Lara Espinosa, Alejandra

    Despite recent interest in understanding long-term trends in ocean acidity, natural variations of carbon chemistry on short timescales are still poorly understood. Unfortunately, historical observations of the oceanic CO2 system are relatively few in number. Such data are particularly scarce along the highly productive Canadian Pacific coast. However, hydrographic data such as temperature, salinity, oxygen and nutrients have been collected regularly in this region. I developed a fully cross-validated statistical model to predict the aragonite saturation state (O arag), a biologically relevant measure of the carbonate system. Different sensitivity tests were performed to assess the robustness of the statistical modelling skill to different model structures. In particular, this study found that in situ temperature and O2 used together were strong predictors of Oarag. The carbon data used to build this statistical model came from five hydrographic surveys along the Pacific coast of Canada (in July 1998, August 2004, late May 2007, February 2010 and early August 2010) that contain direct measurements of CO2 system parameters. Only data from a depth range of 0-750 m were used, as data from below 750 m showed biases due to calcium carbonate dissolution. Although processes such as solar warming and gas exchange occur in the surface and could possibly introduce biases in the model, I show that these surface data can be included. The ability of the statistical models to compute robust estimates of Oarag was assessed by exploring the generalizability of the model through cross-validation procedures using different partitions of the data. By predicting lnOarag rather than O arag directly, I obtained a strong and robust predictive. relationship. This MLR model form yielded a high value in the squared correlation coefficient between predicted and observed values (0.96) and a low percentage in erroneous prediction of undersaturated conditions (3.1%). This relationship was found

    The Manganese sulphate solution has been used for neutron metrology through the method of Manganese Bath. This method uses physical parameters of manganese sulphate solution to obtain its corrections. This work established a functional relationship, using the gravimetric method, between those physical parameters: density, concentration and hydrogen to manganese ratio. Comparisons were done between manganese sulphate solution concentration from the Manganese Bath system of Laboratory of Metrology of Ionising Radiation and estimated values from the functional relationship obtained, showing percentage difference of less than 0.1%. This result demonstrates the usefulness in the correlation of the physical values of the solution to the MB.

    2016-12-01

    Background and aims To review the conceptual and empirical relationship between gambling, investing, and speculation. Methods An analysis of the attributes differentiating these constructs as well as identification of all articles speaking to their empirical relationship. Results Gambling differs from investment on many different attributes and should be seen as conceptually distinct. On the other hand, speculation is conceptually intermediate between gambling and investment, with a few of its attributes being investment-like, some of its attributes being gambling-like, and several of its attributes being neither clearly gambling or investment-like. Empirically, gamblers, investors, and speculators have similar cognitive, motivational, and personality attributes, with this relationship being particularly strong for gambling and speculation. Population levels of gambling activity also tend to be correlated with population level of financial speculation. At an individual level, speculation has a particularly strong empirical relationship to gambling, as speculators appear to be heavily involved in traditional forms of gambling and problematic speculation is strongly correlated with problematic gambling. Discussion and conclusions Investment is distinct from gambling, but speculation and gambling have conceptual overlap and a strong empirical relationship. It is recommended that financial speculation be routinely included when assessing gambling involvement, and there needs to be greater recognition and study of financial speculation as both a contributor to problem gambling as well as an additional form of behavioral addiction in its own right.

    Wang, Haiyun; Tao, Xiaxin

    2003-12-01

    Fault parameters are important in earthquake hazard analysis. In this paper, theoretical relationships between moment magnitude and fault parameters including subsurface rupture length, downdip rupture width, rupture area, and average slip over the fault surface are deduced based on seismological theory. These theoretical relationships are further simplified by applying similarity conditions and an unique form is established. Then, combining the simplified theoretical relationships between moment magnitude and fault parameters with seismic source data selected in this study, a practical semi-empirical relationship is established. The seismic source data selected is also to used to derive empirical relationships between moment magnitude and fault parameters by the ordinary least square regression method. Comparisons between semi-empirical relationships and empirical relationships show that the former depict distribution trends of data better than the latter. It is also observed that downdip rupture widths of strike slip faults are saturated when moment magnitude is more than 7.0, but downdip rupture widths of dip slip faults are not saturated in the moment magnitude ranges of this study.

    Full Text Available Business competition and pressure of European directives put Romanian company in a position to find answers to issues related to long-term survival and development. In this context we believe it is necessary to analyze some of the most important components that should be taken into consideration at the strategic level: national and organizational culture. The results indicate that corporate social responsibility is supported by learning and change-oriented organizational culture, but also by a favorable cultural and national economic framework. Based on these theoretical considerations we intent to emphasize the relationships between national culture / corporate culture and corporate social responsibility (CSR, elaborating an empirical argument by analyzing the results provided by Global 100, an annual project initiated by Corporate Knights Inc.

    Full Text Available A modification of Barro and Sala-i-Martin empirical framework of growth model is specified to examine determinants of per capita growth in 74 Russian regions during period of 1996-2005. We utilize both panel and cross-sectional data. Results imply that in general regional growth in 1996-2005 is explained by the initial level of region's economic development, the 1998 financial crisis, domestic investments, and exports. Growth convergence between poor and rich regions in Russia was not found for the period studied.

  18. Empiric determination of corrected visual acuity standards for train crews.

    Schwartz, Steven H; Swanson, William H

    2005-08-01

    Probably the most common visual standard for employment in the transportation industry is best-corrected, high-contrast visual acuity. Because such standards were often established absent empiric linkage to job performance, it is possible that a job applicant or employee who has visual acuity less than the standard may be able to satisfactorily perform the required job activities. For the transportation system that we examined, the train crew is required to inspect visually the length of the train before and during the time it leaves the station. The purpose of the inspection is to determine if an individual is in a hazardous position with respect to the train. In this article, we determine the extent to which high-contrast visual acuity can predict performance on a simulated task. Performance at discriminating hazardous from safe conditions, as depicted in projected photographic slides, was determined as a function of visual acuity. For different levels of visual acuity, which was varied through the use of optical defocus, a subject was required to label scenes as hazardous or safe. Task performance was highly correlated with visual acuity as measured under conditions normally used for vision screenings (high-illumination and high-contrast): as the acuity decreases, performance at discriminating hazardous from safe scenes worsens. This empirically based methodology can be used to establish a corrected high-contrast visual acuity standard for safety-sensitive work in transportation that is linked to the performance of a job-critical task.

  19. Empirical relationships between gas abundances and UV selective extinction

    International Nuclear Information System (INIS)

    Joseph, C.L.

    1990-01-01

    Several studies of gas-phase abundances in lines of sight through the outer edges of dense clouds are summarized. These lines of sight have 0.4 less than E(B-V) less than 1.1 and have inferred spatial densities of a few hundred cm(-3). The primary thrust of these studies has been to compare gaseous abundances in interstellar clouds that have various types of peculiar selective extinction. To date, the most notable result has been an empirical relationship between the CN/Fe I abundance ratio and the depth of the 2200 A extinction bump. It is not clear whether these two parameters are linearly correlated or the data are organized into two discrete ensembles. Based on 19 samples lines of sight that have a CN/Fe I abundance ratio greater than 0.3 (dex) appear to have a shallow 2.57 plus or minus 0.55 bump compared to 3.60 plus or minus 0.36 for other dense clouds and compared to the 3.6 Seaton (1979) average. The difference in the strength of the extinction bump between these two ensembles is 1.03 plus or minus 0.23. Although a high-resolution IUE survey of dense clouds is far from complete, the few lines of sight with shallow extinction bumps all show preferential depletion of certain elements, while those lines of sight with normal 2200 A bumps do not. Ca II, Cr II, and Mn II appear to exhibit the strongest preferential depletion. Fe II and Si II depletions also appear to be enhanced somewhat. It should be noted that Copernicus data suggest all elements, including the so-called nondepletors, deplete in diffuse clouds (Snow and Jenkins 1980, Joseph 1988). Those lines of sight through dense clouds that have normal 2200 A extinction bumps appear to be extensions of the depletions found in the diffuse interstellar medium

  20. Energy efficiency determinants: An empirical analysis of Spanish innovative firms

    International Nuclear Information System (INIS)

    Costa-Campi, María Teresa; García-Quevedo, José; Segarra, Agustí

    2015-01-01

    This paper examines the extent to which innovative Spanish firms pursue improvements in energy efficiency (EE) as an objective of innovation. The increase in energy consumption and its impact on greenhouse gas emissions justifies the greater attention being paid to energy efficiency and especially to industrial EE. The ability of manufacturing companies to innovate and improve their EE has a substantial influence on attaining objectives regarding climate change mitigation. Despite the effort to design more efficient energy policies, the EE determinants in manufacturing firms have been little studied in the empirical literature. From an exhaustive sample of Spanish manufacturing firms and using a logit model, we examine the energy efficiency determinants for those firms that have innovated. To carry out the econometric analysis, we use panel data from the Community Innovation Survey for the period 2008–2011. Our empirical results underline the role of size among the characteristics of firms that facilitate energy efficiency innovation. Regarding company behaviour, firms that consider the reduction of environmental impacts to be an important objective of innovation and that have introduced organisational innovations are more likely to innovate with the objective of increasing energy efficiency. -- Highlights: •Drivers of innovation in energy efficiency at firm-level are examined. •Tangible investments have a greater influence on energy efficiency than R&D. •Environmental and energy efficiency innovation objectives are complementary. •Organisational innovation favors energy efficiency innovation. •Public policies should be implemented to improve firms’ energy efficiency

  1. An Empirical State Error Covariance Matrix Orbit Determination Example

    Science.gov (United States)

    Frisbee, Joseph H., Jr.

    2015-01-01

    State estimation techniques serve effectively to provide mean state estimates. However, the state error covariance matrices provided as part of these techniques suffer from some degree of lack of confidence in their ability to adequately describe the uncertainty in the estimated states. A specific problem with the traditional form of state error covariance matrices is that they represent only a mapping of the assumed observation error characteristics into the state space. Any errors that arise from other sources (environment modeling, precision, etc.) are not directly represented in a traditional, theoretical state error covariance matrix. First, consider that an actual observation contains only measurement error and that an estimated observation contains all other errors, known and unknown. Then it follows that a measurement residual (the difference between expected and observed measurements) contains all errors for that measurement. Therefore, a direct and appropriate inclusion of the actual measurement residuals in the state error covariance matrix of the estimate will result in an empirical state error covariance matrix. This empirical state error covariance matrix will fully include all of the errors in the state estimate. The empirical error covariance matrix is determined from a literal reinterpretation of the equations involved in the weighted least squares estimation algorithm. It is a formally correct, empirical state error covariance matrix obtained through use of the average form of the weighted measurement residual variance performance index rather than the usual total weighted residual form. Based on its formulation, this matrix will contain the total uncertainty in the state estimate, regardless as to the source of the uncertainty and whether the source is anticipated or not. It is expected that the empirical error covariance matrix will give a better, statistical representation of the state error in poorly modeled systems or when sensor performance

  2. Relationships between Unemployment and Economic Growth - the Review (Results of the Theoretical and Empirical Research

    Directory of Open Access Journals (Sweden)

    Katarzyna Nagel

    2015-04-01

    Full Text Available The article aims to discuss the relationship between economic growth and unemployment as well as related determinant factors based on literature review. The traditional approach presents this relationship through the prism of the effects of creation, capitalization, pool of savings and creative destruction. Nowadays, an increasing number of researchers attach more importance to the impact of institutional factors, such as minimum and efficiency wages or the flexibility of the labor market. Both theoretical and empirical research reveal both the evolution of the relevant views and the lack of consistency between the concepts explaining the relationship between economic growth and unemployment in different regions of the world and in different groups of countries.

    Full Text Available This paper studies the relationship between innovativeness and strategic planning in SMEs. In introduction part, the authors attempt to consider relevant findings about this specific relationship in the literature. The paper presents how the EU policy approaches the innovation management system within SMEs and where Serbia stands in catching up the process towards the EU in terms of innovativeness and competitiveness. The main research approach is to examine the relationship between innovativeness and strategic orientation, beginning with the existence of the four key strategic business documents: strategic, marketing, business plan and procedures, and innovation strategy documents. The last part is a discussion on the findings and considerations of the intensity of the relations among strategic orientations of the company expressed through the key strategic documents and innovativeness, and the relations among the three most practiced types of innovation in representative sample of 150 Serbian small and medium enterprises (SMEs.The research has shown that there is positive correlation between strategic planning approach in marketing and firm's innovativeness but the intensity of the relationship depends on the type of the innovativeness considered.

    Full Text Available The majority of policymakers believe that investments in construction infrastructure would boost the economy of the United States (U.S.. They also assume that construction investment in infrastructure has similar impact on the economies of different U.S. states. In contrast, there have been studies showing the negative impact of construction activities on the economy. However, there has not been any research attempt to empirically test the temporal relationships between construction investment and economic growth in the U.S. states, to determine the longitudinal impact of construction investment on the economy of each state. The objective of this study is to investigate whether Construction Value Added (CVA is the leading (or lagging indicator of real Gross Domestic Product (real GDP for every individual state of the U.S. using empirical time series tests. The results of Granger causality tests showed that CVA is a leading indicator of state real GDP in 18 states and the District of Columbia; real GDP is a leading indicator of CVA in 10 states and the District of Columbia. There is a bidirectional relationship between CVA and real GDP in 5 states and the District of Columbia. In 8 states and the District of Columbia, not only do CVA and real GDP have leading/lagging relationships, but they are also cointegrated. These results highlight the important role of the construction industry in these states. The results also show that leading (or lagging lengths vary for different states. The results of the comparative empirical analysis reject the hypothesis that CVA is a leading indicator of real GDP in the states with the highest shares of construction in the real GDP. The findings of this research contribute to the state of knowledge by quantifying the temporal relationships between construction investment and economic growth in the U.S. states. It is expected that the results help policymakers better understand the impact of construction investment

    International Nuclear Information System (INIS)

    Sadorsky, P.

    2000-01-01

    This paper investigates the interaction between energy futures prices and exchange rates. Results are presented to show that futures prices for crude oil, heating oil and unleaded gasoline are co-integrated with a trade-weighted index of exchange rates. This is important because it means that there exists a long-run equilibrium relationship between these four variables. Granger causality results for both the long- and short-run are presented. Evidence is also presented that suggests exchange rates transmit exogenous shocks to energy futures prices. 22 refs

  16. Relationship Between Supply Chain Risks: An Empirical Work

    2017-06-01

    Full Text Available Supply chain risk management is turned out to be a critical function for organization around the globe as a consequence of change in technology, economic, environment of organizations. Most companies or organizations view supply chain risk as a disruption of the flow of products or services that meet their requirements and consequently reduce their performance. A literature review for this study indicates that relationship between supply chain risks and developing appropriate mitigation strategies is drawing the attention of practitioners and academics in recent years. However, there is a lack of studies in this field. This paper aims to contribute to fill this gap in the literature by exploring the relationships between supply chain risks in Nigeria. To this end, data were collected 82 companies operating in different industries. Correlation matrices and item to total correlations were used for the analysis. The results indicated that terrorist activity risk is the most perceived supply chain risk in Nigeria. It was also found that many companies can reduce the level of many supply chain risks with an optimum level of capacity and good planning. It is expected that the findings help supply chain managers and policy makers in their decisions.

    2014-11-01

    Full Text Available Entrepreneurship is fundamental for a country's economic development through its positive effect on innovation, productivity growth, and job creation. In entrepreneurial research, one of the most important problems is to define the factors that actually determine entrepreneurial action. This study analyzes that question in the case of Germany by taking an aggregated approach that focuses on socio-demographic and economic determinants of regional entrepreneurship. Based on a literature review of German and international regional-level research, six hypotheses are developed and empirically tested using the most recent available data on 385 German regions as units of analysis. The results are surprising. In the case of household income, unemployment, education and marital status the relationship is significant but contrary to earlier research. Only regional age structure seems to be a stable predictor of regional entrepreneurship. The results indicate that in recent years there was a major shift in the determinants and characteristics of entrepreneurship in Germany.

    1981-01-01

    New ultraviolet colors are presented for 110 hot stars. These data are combined with infrared colors and diffuse-band measurements to study the relationship of diffuse interstellar bands (lambdalambda4430, 5780, 6284) to the overall extinction curve. Equivalent widths of lambdalambda5780 and 6284 are not well correlated with infrared, visible, or ultraviolet extinction measurements for stars in our sample. The central depth of lambda4430 is well correlated with visible and infrared extinction, but less well correlated with UV extinction at 1800 A. lambda4430 is strongly correlated with the strength of the 2200-A bump. Our data suggest that if small grains account for the general rise in UV extinction, the diffuse bands are not formed in these grains. lambda4430 may well arise in large grains and/or in the material responsible for the 2200-A bump. Correlations with UV extinctions derived by other authors are discussed in detail. It is suggested that definitions of extinction parameters and band shapes, as well as selection effects in small samples of stars, may still compromise conclusions based on correlation studies such as we are attempting

    Full Text Available A view prominently expounded is that the interaction between the composition and the volume of public expenditures is directly affected by political, institutional, psephological and ideological indicators. A crucial component of public expenditures, social expenditures play an important role in the economy as they directly and indirectly affect the distribution of income and wealth. Social expenditures aim at reallocating income and wealth unequal distribution. These expenditures comprise cash benefits, direct in-kind provision of goods and services, and tax breaks with social purposes.The aim of this study is to determine the relationship between political structure, i.e. government fragmentation, ideological composition, elections and so on, and the social expenditures in Greece. Employing data from the Comparative Political Dataset (CPDS and the OECD Social Expenditure Database (SOCX, a time series analysis was conducted for Greece for the 1980-2014 period. The findings of the study indicate that voter turnout, spending on the elderly population and the number of government changes have positive and statistically significant effects on social expenditures in Greece while debt stock and cabinet composition have negative effects.

    Recently, most European countries have undergone integration processes through mergers and strategic alliances between healthcare organizations. The present paper examined three cases within the Italian National Health Service in order to determine how different organizations, within differing institutional contexts, govern an healthcare integration process. Furthermore, we explored the possibility that the governance mode, usually seen as alternatives (i.e., merger or alliance), could be considered as a separate step in the development of a more suitable integration process. Multiple case studies were used to compare different integration approaches. Specifically, three cases were considered, of which two were characterized by collaborative processes and the other by a merger. Semi-structured interviews were conducted with managers involved in the processes. Each case presents different governing modes, structures, and mechanisms for achieving integration. The role played by the institutional context also led to different results with unique advantages and disadvantages. Three main conclusions are discussed: (a) Alliances and mergers can be interpreted as different steps in a path leading to a better integration; (b) The alignment between institutional/political time horizon and the time needed for the organizations to achieve an integration process lead to a better integration; (c) Trust plays an important role in integration process operating at different levels that of institutional and organizational level and that built between people.

    Full Text Available Chocolate is one of popular gifts among people in many societies. Packaging of such product plays an important role on marketing this item and the primary question of this survey is to determine the impact of packaging on better introducing a product. The inference statistical tests show that packaging is an important item in selection of chocolate as a gift. Percentage of chocolate is the most important information on packaging and color of packaging is of paramount significance when customers purchase chocolate for individuals with official relationship. In this paper, we present an empirical study to measure the effects of chocolates' packaging on purchasing them. The proposed study of this paper designs a questionnaire and distributes them among different people. The results are analyzed using some non-parametric tests and they are discussed. The preliminary results indicate that the number of purchased packages within a year, cost of purchasing chocolate within a year, type of relationship of recipients of chocolate as gift, gender of recipient of chocolate as gift, age group of recipient of gift, type of store, nationality of chocolate, significance of packaging in various price ranges, type of packaging, insertion of information on package and color of packaging, are important factors influencing people to buy more.

    2017-04-01

    Full Text Available Orientation: A critical reading of the human resource management (HRM literature finds limited contributions to understanding the organisational determinants of social enterprises and how these may contribute to higher levels of social innovativeness. Although innovation is a key theme in organisational research it has been acknowledged that the field needs more theory-based examinations of different types of innovativeness. Research purpose: To determine how different organisational capabilities are related to social innovation. Motivation for the study: Many social enterprises in developing countries do not have the requisite capabilities to efficiently manage all their programmes, which presents a major threat to organisational sustainability. Research design, approach and method: The empirical analysis is a cross-sectional study based on primary survey data. Hypotheses are tested using correlational and regression analysis. Main findings: The results show that the organisational learning capabilities of knowledge conversion, risk management, organisational dialogue and participative decision-making all have a significant and positive relationship with social innovation. Practical/managerial implications: Managers and practitioners can leverage the different organisational learning capabilities to improve social innovations in their social enterprises. Contribution/value-add: The study is one of the first in an African market context to empirically investigate social enterprises in terms of social innovation and organisational learning perspectives.

  10. Building Strong Customer Relationships through Brand Orientation in Small Service Firms: An Empirical Investigation

    Directory of Open Access Journals (Sweden)

    Miloslava Chovancová

    2015-06-01

    Full Text Available The purpose of this paper is to empirically examine the relationship between the adoption of a brand orientation strategy and customer relationship performance in a small service firm setting. More specifically, in addition to investigating the direct link between brand orientation and customer relationship performance, we further examine the moderating effects of entrepreneurial orientation and perceived competitive intensity on the empirical link between brand orientation and customer relationship performance. To test the hypothesized relationships in the conceptual framework, 105 usable structured questionnaires were collected from small service firms and the data were further analyzed using a hierarchical, moderated regression analysis. The results affirm the positive link between brand orientation and customer relationship performance. Moreover, entrepreneurial orientation is found to strengthen the brand orientation-customer relationship performance link. However, our results show that competitive intensity does not significantly moderate the brand orientation-customer relationship performance link. Nonetheless, it is highly suggestive that perceived competitive intensity is a direct predictor of customer relationship performance. In terms of the practical significance of the overall research model, the effect size is fairly large (Cohen’s f 2 = 0.33. The research implications and directions for future research are further highlighted in the penultimate section of the paper.

  11. An empirical study of desired versus actual compensation practices in determining intrapreneurial behaviour

    Directory of Open Access Journals (Sweden)

    Ugochukwu O. Madu

    2014-08-01

    Full Text Available Orientation: Past research recognises that human resources management practices may influence innovative behaviour, particularly as compensation systems can be used as a tool to increase intrapreneurial activity. Research purpose: The aim of this study is to determine the relationship between actual versus desired compensation practices and elevated intrapreneurial behaviour. This is in line with research that focuses on how to promote business innovation, rather than merely research whether innovation is desirable for businesses or not. Motivation for the study: Recognising that entrepreneurial actions are the bedrock of intrapreneurial behaviour and that these behaviours may be critical to the long-term vitality of a firm and economy, it is important to facilitate the empirical study of them in an underresearched, emerging market environment. Moreover, compensation such as reward preferences and variable pay schemes remain controversial in terms of their costs versus contributions, and these constructs deserve more empirical research. Research approach, design and method: The study employed a quantitative research design, using a cross-sectional and empirical approach with primary data sources. A structured webbased instrument rendered a sample of 209 respondents from a diverse set of businesses. Canonical correlational analysis was carried out to test the hypotheses. Main findings: The results reveal that a gap exists between an employee’s perception of desired compensation practices and the actual compensation practices. The results further highlight that non-outcome-based measures like pay risk, job risk and expectations of success play a role in determining whether employees decide to be intrapreneurial or not. Practical/managerial implications: Due to the potential impact rewards have on intrapreneurial behaviour, it is necessary to design relevant compensation systems as part of organisational architecture in order to foster

    2016-12-01

    Full Text Available Market knowledge, market orientation, learning competencies, and a business performance were the key issues of the research project conducted in the 2006 study. The main findings identified significant relationships between the independent variables (market knowledge, market orientation, learning competencies and the dependent variables (business success. A partial correlation analysis indicated that a business success primarily relies on organisational learning competencies. Organisational learning competencies, to a large extent (almost 60%, may be explained by the level of corporate market knowledge and market orientation. The aim of the paper is to evaluate to what extent the relationships between the variables are still valid. The research was based on primary and secondary data sources. The major field of the research was carried out in the form of quantitative studies. The results of the 2014 study are consistent with the previous (2006 results.

    Full Text Available The ethical position of organizations is of great importance to both organizations and society in general considering people spend their considerable lifespan in organizations. It is important to sustain the determination on ethics by detecting and revealing the ethical infringements inside the organization. In this context; whistleblowing, which is a concept deriving from the field of organizational psychology is defined as the action that informing the individuals and organizations for the on-going unethical and amoral activities in the organizations, has become important. The courage of individuals to report unethical, immoral or illegal activities to the authorities can be affected by the attitude of individuals towards the organization. One of the attitudes that are considered to affect that courage, which is named as whistleblowing, is organizational commitment. Organizational commitment shows the loyalty of employees to the organization. In this study it has been examined the relationship between employees’ organizational commitment and tendency to reporting immoral behaviours. The sample of the study is composed of the employees of Faculty of Economics and Administrative Sciences at Selcuk University. For this empirical study, survey method has been used, and the reached sample chosen by simply random sampling is 88 employees.

    Full Text Available This study investigates the determinants of FDI to Nigeria during 1970-2006. This study suggests that the endowment of natural resources, trade intensity, macroeconomic risk factors such as inflation and exchange rates are significant determinants of FDI flow to Nigeria. The findings suggest that in long run, market size is not the significant factor for attracting FDI to Nigeria, it contradicts the existing literature. The findings indicate that FDI to Nigeria is resource-seeking. Results also suggest that trading partner like the UK in North-South (N - S and China in South-South (S - S trade relation have strong influence on Nigeria’s natural resource outflow.

    These days, most of the Malaysians realize that the consumption of debit card will help them to reduce the household debt. Thus, it is important to analyse the acceptance of debit cards for further enhancement and expanding its market share in Malaysia. In addition, there is lacked of research being conducted on the determinants affecting the acceptance of debit cards among Malaysians. Thus, the study aimed to investigate the factors affecting the acceptance of debit cards. This study focuses on payment methods, consumer attitude, and safety of debit card in acceptance of debit cards. Questionnaires were distributed to the 300 respondents. The sampling procedure adopted was stratified random sampling. The data obtained were analysed using SPSS 20.0 which involves scale reliability, descriptive and regression analysis. The result indicates that payment methods, consumer attitude and safety are the determinants of debit cards acceptance. Safety is the best predictor as most of the customers are confidents to use debit cards because of the security being developed around these debit card transactions. The analyses presented in this study can be used by policymakers and managers as a guide to promote banking products and services. The findings achieved in this study will be of interest for practitioners and academics concerned with developments of the Malaysian banking industry

  4. Determinants of China's energy imports: An empirical analysis

    International Nuclear Information System (INIS)

    Zhao, Xingjun; Wu, Yanrui

    2007-01-01

    Sustained economic growth in China has triggered a surge of energy imports, especially oil imports. This paper investigates the determinants of China's energy import demand by using cointegraiton and VECM techniques. The findings suggest that, in the long run, growth of industrial production and expansion of transport sectors affect China's oil imports, while domestic energy output has a substitution effect. Thus, as the Chinese economy industrializes and the automotive sector expands, China's oil imports are likely to increase. Though China's domestic oil production has a substitution effect on imports, its growth is limited due to scarce domestic reserve and high exploration costs. It is anticipated that China will be more dependent on overseas oil supply regardless of the world oil price. (author)

    Alaiad, Ahmad; Zhou, Lina

    2014-11-01

    Home healthcare robots promise to make clinical information available at the right place and time, thereby reducing error and increasing safety and quality. However, it has been frequently reported that more than 40% of previous information technology (IT) developments have failed or been abandoned due to the lack of understanding of the sociotechnical aspects of IT. Previous home healthcare robots research has focused on technology development and clinical applications. There has been little discussion of associated social, technical and managerial issues that are arguably of equal importance for robot success. To fill this knowledge gap, this research aims to understand the determinants of home healthcare robots adoption from these aspects by applying technology acceptance theories. We employed both qualitative and quantitative methods. The participants were recruited from home healthcare agencies located in the U.S. (n=108), which included both patients and healthcare professionals. We collected data via a survey study to test a research model. The usage intention of home healthcare robots is a function of social influence, performance expectancy, trust, privacy concerns, ethical concerns and facilitating conditions. Among them, social influence is the strongest predictor. Monitoring vital signs and facilitating communication with family and medication reminders are the most preferable tasks and applications for robots. Sociotechnical factors play a powerful role in explaining the adoption intention for home healthcare robots. The findings provide insights on how home healthcare service providers and robot designers may improve the success of robot technologies. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  8. An Empirical Study on Public Debt's Determinants: Evidence from Romania

    2013-02-01

    Full Text Available The need for coordinating economic and budgetary policies in the Economic and Monetary Union, the awareness that pile of high public debt threatens future generations, increasing tax burden on a globalized market and the impact of population aging process on public finances has led to controversial opinions. Continuously borrowing resources and maintaining them consistently over time means to have a sustainable public debt, an important objective of any state fiscal policy. A sustainable public debt is the result of trade and monetary policy and budgetary decisions. The national debt is at the center of the current crisis of the Peripheral European countries. The objective of the paper is to provide a better understanding of public debt dynamics in Romania in the period 2000 to 2011. We decompose the changes in public debt to GDP ratio into macroeconomic components attributable to primary fiscal deficits, real interest rate, real GDP growth, and to the variations on foreign currency denominated debt. The research findings suggest that the reaction of the public debt to GDP ratio to the real growth rate of the output increased after the financial crisis. The real interest rate on government bonds remained a significant determinant of public debt in the entire sample period. Also, we find little effectiveness of monetary policy as an automatic stabilizer through the entire sample period.

    Full Text Available Leadership plays an important role among five main components of management. These days, many organizations try to resolve any existing conflicts through adapting an appropriate leadership strategy. During the past few years, there are increasing interests in examining the relationship between management style and conflict management. The proposed study of this paper performs an empirical study to find the relationship between relationship-oriented leadership style and solution-oriented strategy as well as between leadership style and conflict management. The proposed study distributed a questionnaire among 43 managers who were in different industries in west part of Iran. Most of the people who participated in our survey were male and they were between 25 to 30 years old. The study considers relationship between leadership style and conflict management, which includes the relationship between relationship-oriented and task-oriented leaderships with avoiding conflict management strategy, solution and control based conflict managements. The results confirmed that there is only a meaningful relationship between relationship-oriented leadership with solution-based conflict management. In other words, our survey indicates that when there is a conflict, management can handle the problem using his/her relationship and find appropriate solution to resolve any possible conflict.

Thereafter, multiple regression analysis was conducted using pooled ordinary least squares and the panel estimated generalized least squares. Consistent with other prior research, the results for audit client characteristics revealed that audit client size and complexity have a positive and significant impact on audit fee while profitability, fiscal year end and industry have a negative and significant influence on audit fee. For corporate governance variables, board diligence, board expertise, board size, board independence, and audit committee independence, all have a positive and significant impact on audit fee. For audit firm characteristics, audit firm type, and international linkage have a positive and significant impact on audit fee while audit firm tenure has a negative and significant impact on audit fee. It is recommended that auditors should have a better understanding of these factors and their relative importance and how the factors might be built into an audit fee model.

    Full Text Available From the 1950s to 1980, the copper mining industry exhibited a phenomenal growth rate. However, beginning in the early 1980s through 1997, growth rate turned negative without any sign of reversal. In order to restore the important role the industry used to play in the economy, policy makers, and decision makers must understand the factors responsible for the rapid growth from the 1950s until 1980 and the equally rapid decline during the 1980s and the 1990s.Growth of the copper mining industry is examined within the framework of a production function to identify the determinants of growth and their roles. The explanatory variables of growth are: copper resources, risk capital or investments, development in the world’s copper market, technology, human capital in mining, and domestic social, legal, and political environment. Except for copper resources, which has been supportive of positive growth, all the variables have components that supported the growth of the copper mining industry during the 1950s-1980s period and contributed to its decline thereafter.Availability of foreign capital, introduction of bulk mining technology, favorable copper prices and demand, and a conducive domestic social, political, and legal environment were responsible for the impressive growth experienced during the period from the 1950s to 1980. On the other hand, lack of foreign investment, declining market demand and prices, inadequate experience of local executives in the functions of top technical and managerial positions after 1974, arbitrary fiscal policies, lack of mining laws from 1986 to 1995, contradictory laws thereafter, and an uncertain domestic political, social, and legal environment caused the negative growth rates in the 1980s and 1990s. The 1995 Mining Code, which allows 100 percent foreign investments in mining under the financial and technical assistance mode of mineral disposition, could have revived the industry after 1995 were it allowed to

    This paper proposes a new empirical model for examining the relationship between obesity and school performance using the simultaneous equation modelling approach. The lagged effects of both learning and health outcomes were included to capture both the dynamic and inter-relational aspects of the relationship between obesity and school performance. The empirical application of this study used comprehensive data from the first five waves of the Longitudinal Study of Australian Children (LSAC), which commenced in 2004 (wave 1) and was repeated every two years until 2018. The study sample included 10,000 children, equally divided between two cohorts (infants and children) across Australia. The empirical results show that past learning and obesity status are strongly associated with most indicators of school outcomes, including reading, writing, spelling, grammar and numeracy national tests, and scores from the internationally standardized Peabody Picture Vocabulary Test and the Matrix Reasoning Test. The main findings of this study are robust due to the choice of obesity indicator and estimation methods.

    This paper aims at reassessing the empirical relationship between the real price of oil and the U.S. dollar real effective exchange rate over the 1974–2015 period. We find that changes in both variables are now linked by a negative relationship, going from the dollar exchange rate to the real oil price. However, the same relationship is found positive when ending the sample in the mid-2000s, in line with the previous literature. To understand and investigate this evolution, we rely on a nonlinear, smooth transition regression model in which the oil price-dollar nexus depends on the dynamics followed by the U.S. currency. Our results show that the relationship is negative most of the times but turns positive when the dollar hits very high values, as in the early eighties. - Highlights: •We reassess the relationship between the real oil price and the dollar over the 1974–2015 period. •Changes in the two variables are linked by a negative relationship over the whole period. •The link between both variables is positive over the subsample ending in the mid-2000s. •We estimate a nonlinear model in which the oil price-dollar nexus depends on the evolution the dollar. •The relationship is negative most of the times, except when the dollar hits very high values.

    2002-06-15

    Two experimental methods are described in this paper: one for determining the empirical formula, and one for determining the energy content of unknown organics in waste streams. The empirical formula method requires volatile solids (VS), chemical oxygen demand (COD), total organic carbon (TOC), and total Kjeldahl nitrogen (TKN) to be measured for the waste; the formula can then be calculated from these values. To determine the energy content of the organic waste, bomb calorimetry was used with benzoic acid as a combustion aid. The results for standard compounds (glucose, propionic acid, L-arginine, and benzoic acid) were relatively good. The energy content measurement for wastewater and sludges had good reproducibility (i.e. 1.0 to 3.2% relative standard deviation for triplicate samples). Trouble encountered in the measurement of the empirical formulae of the waste samples was possibly due to difficulties with the TOC test; further analysis of this is required. (author)

    2010-07-01

    Our purpose in this study was to meta-analytically address several theoretical and empirical issues regarding the relationships between safety climate and injuries. First, we distinguished between extant safety climate-->injury and injury-->safety climate relationships for both organizational and psychological safety climates. Second, we examined several potential moderators of these relationships. Meta-analyses revealed that injuries were more predictive of organizational safety climate than safety climate was predictive of injuries. Additionally, the injury-->safety climate relationship was stronger for organizational climate than for psychological climate. Moderator analyses revealed that the degree of content contamination in safety climate measures inflated effects, whereas measurement deficiency attenuated effects. Additionally, moderator analyses showed that as the time period over which injuries were assessed lengthened, the safety climate-->injury relationship was attenuated. Supplemental meta-analyses of specific safety climate dimensions also revealed that perceived management commitment to safety is the most robust predictor of occupational injuries. Contrary to expectations, the operationalization of injuries did not meaningfully moderate safety climate-injury relationships. Implications and recommendations for future research and practice are discussed.

    2014-07-01

    Full Text Available In the context of the present economic crisis, entrepreneurship has re-emerged as a topic of interest both for policy makers worldwide as well as for academic research. A wide range of psychological, economic and sociological factors influencing entrepreneurial activity is presented by the existing literature. The aim of this paper is to identify the economic and institutional factors that influenced entrepreneurial activity both before and during the crisis. Data for 27 countries worldwide from Global Entrepreneurship Monitor, World Bank World Development Indicators and World Bank’s Worldwide Governance Indicators international databases were collected for the years 2007, 2009 and 2012. A three stage empirical research was conducted: a comparative analysis of the distribution of the selected variables for the three years, principal components analysis in order to provide an image of the intensity and direction of the relationship between the variables and to characterize the statistical units and econometric modelling to describe the variation of entrepreneurial activity in relation with its economic and institutional determinants. Contrary to expectations, the research findings show that before the crisis, the variation of entrepreneurial activity is explained by the negative influence of the perceived confidence in the rules of society and during the crisis it is negatively influenced by the perceived government effectiveness. The limitations of the research are also presented.

    Full Text Available We studied the relationship between investor protection, government behavior, and financial development using data covering six provinces (Guangdong, Jiangsu, Shandong, Zhejiang, Henan, and Sichuan and two provincial-level cities (Beijing and Shanghai in China for the period 2005–2014. Using panel data estimation techniques, we found that there is a positive relationship between investor protection and financial development; by contrast, highly-intense government intervention leads to more financial impediments. Moreover, government intervention in education could promote financial development through its contribution to having a higher amount of the fund supply. Our empirical findings have important implications for policy-makers in terms of reforming the capital market regulation.

    The objective of this paper is to verify the hypotheses presented in the literature on the causal relationship between inflation and its uncertainty, for the newest EU countries. To ensure the robustness of the results, in the study four models for inflation uncertainty are estimated in parallel: ARCH (1), GARCH (1,1), EGARCH (1,1,1) and PARCH (1,1,1). The Granger method is used to test the causality between two variables. The working hypothesis is that groups of countries with a similar political and economic background in 1990 and are likely to be characterized by the same causal relationship between inflation and inflation uncertainty. Empirical results partially confirm this hypothesis. C22, E31, E37.

    Full Text Available It has been proposed that emotion regulation (ER is a factor with a predictive capacity for academic performance. However, empirical studies are scarce and relatively little is still known about the specific relationship of RE strategies and abilities with different indicators of academic performance. The aim of this study was to identify the state of the art regarding the relationship of emotional regulation with academic performance. A systematic search of empirical articles was conducted in the databases Google Scholar, ERIC and PsyArticles combining the terms emotion regulation or emotion self-regulation with: (academic abilities, competency, achievement, success, performance, learning, school, literacy, classroom, education, reading, math. There were selected 17 items. The analysis allowed two groups to be formed. In the first group, articles evaluating ER strategies were considered. Among these studies, experimental designs and behavioral indicators predominated as ER measures. In the second group, studies evaluating ER skills were considered. In this group, studies with cross-sectional designs and measures of self-report or other reports to evaluate ER were predominant. It concludes with recommendations for future work.

    Full Text Available This study estimates the effects of a prospective payment system on the growth of for-profit hospitals. The empirical results show that the proportion of patient care paid for by Medicare managed care has a positive, statistically significant relationship with the market share of for-profit hospitals. Medicare managed care reimburses health care providers prospectively, and a larger portion of prospective reimbursements is received by for-profit hospitals, whose market share consequently increases. In addition, the proportion of patients with Medi-Cal and third party managed care has a positive, statistically significant relationship with the market share of for-profit hospitals.

  6. Identifying the oil price-macroeconomy relationship. An empirical mode decomposition analysis of US data

    Oladosu, Gbadebo

    2009-01-01

    This paper employs the empirical mode decomposition (EMD) method to filter cyclical components of US quarterly gross domestic product (GDP) and quarterly average oil price (West Texas Intermediate - WTI). The method is adaptive and applicable to non-linear and non-stationary data. A correlation analysis of the resulting components is performed and examined for insights into the relationship between oil and the economy. Several components of this relationship are identified. However, the principal one is that the medium-run component of the oil price has a negative relationship with the main cyclical component of the GDP. In addition, weak correlations suggesting a lagging, demand-driven component and a long-run component of the relationship were also identified. Comparisons of these findings with significant oil supply disruption and recession dates were supportive. The study identifies a number of lessons applicable to recent oil market events, including the eventuality of persistent oil price and economic decline following a long oil price run-up. In addition, it was found that oil market related exogenous events are associated with short- to medium-run price implications regardless of whether they lead to actual supply losses. (author)

  8. New empirical relationship between grain size distribution and hydraulic conductivity for ephemeral streambed sediments

    KAUST Repository

    Rosas, Jorge

    2014-07-19

    Grain size distribution, porosity, and hydraulic conductivity were determined for 39 sediment samples collected from ephemeral streams (wadis) in western Saudi Arabia. The measured hydraulic conductivity values were then compared to values calculated using 20 different empirical equations commonly used to estimate hydraulic conductivity from grain size analyses. It was found that most of the hydraulic conductivity values estimated from the empirical equations correlated very poorly with the measured hydraulic conductivity values. Modifications of the empirical equations, including changes to special coefficients and statistical offsets, were made to produce modified equations that considerably improved the hydraulic conductivity estimates from grain size data for wadi sediments. The Chapuis, Hazen, Kozeny, Slichter, Terzaghi, and Barr equations produced the best correlations, but still had relatively high predictive errors. The Chapius equation was modified for wadi sediments by incorporating mud percentage and the standard deviation (in phi units) into a new equation that reduced the predicted hydraulic conductivity error to ±14.1 m/day. The equation is best applied to ephemeral stream samples that have hydraulic conductive values greater than 2 m/day.

    The observation periods and thresholds of serum creatinine and urine output defined in the Acute Kidney Injury Network (AKIN) criteria were not empirically derived. By continuously varying creatinine/urine output thresholds as well as the observation period, we sought to investigate the empirical relationships among creatinine, oliguria, in-hospital mortality, and receipt of renal replacement therapy (RRT). Using a high-resolution database (Multiparameter Intelligent Monitoring in Intensive Care II), we extracted data from 17,227 critically ill patients with an in-hospital mortality rate of 10.9 %. The 14,526 patients had urine output measurements. Various combinations of creatinine/urine output thresholds and observation periods were investigated by building multivariate logistic regression models for in-hospital mortality and RRT predictions. For creatinine, both absolute and percentage increases were analyzed. To visualize the dependence of adjusted mortality and RRT rate on creatinine, the urine output, and the observation period, we generated contour plots. Mortality risk was high when absolute creatinine increase was high regardless of the observation period, when percentage creatinine increase was high and the observation period was long, and when oliguria was sustained for a long period of time. Similar contour patterns emerged for RRT. The variability in predictive accuracy was small across different combinations of thresholds and observation periods. The contour plots presented in this article complement the AKIN definition. A multi-center study should confirm the universal validity of the results presented in this article.

  11. Some empirical evidence on the relationship between inventory management and social responsibility

    2013-09-01

    Full Text Available Despite the crucial role that inventory plays in supply chain management (SCM, research that examines the relationship between inventory and corporate social responsibility (CSR is rare. This is surprising given the evidence that inventory represents a huge source of cost, a matter that is often reported as a major impediment in practicing social responsibility in SCM. As such, this paper fills this gape in literature by examining directly the effect of inventory management on CSR. Maximum-likelihood ordered logistic regression was performed on a sample of 38 Egyptian listed firms during the period from 2007 to 2010. The results demonstrate that inventory management exerts a positive and significant coefficient on CSR. Further analysis shows that inventory management cannot be safely dropped from model of analysis. Rather, inventory management does add something unique in explaining differences in CSR. For practitioners interested in optimizing their firms’ values, thinking in managing supply chain imperatives, and specially inventory, in terms of social responsibility may guide them to build up a stock of reputational capital that can be used, in turn, to increase the cost of their rivals. This study, to the best of knowledge, is the first one that offers empirical evidence regarding the effect of inventory management on CSR. Moreover, the paper adds to both SCM and CSR literature by providing empirical evidence from Egypt as an emerging market, where much of the existing evidence reflects experience from developed countries.

    2017-01-01

    Full Text Available Corporate Volunteering (CV is a phenomenon that emerged in the second half of the 20th century and began to grow and globalize at the beginning of the 21st century. There seems to be a consensus that the recent growth of Corporate Volunteering is related to the development and growing legitimacy of the concept of Corporate Social Responsibility (CSR. Nevertheless, the theoretical discussion on how the two concepts (Corporate Volunteering and Corporate Social Responsibility are related is just beginning, while empirical research on how this relationship operates in corporate practice is still incipient. This paper presents preliminary results of a research on this subject carried out in Uruguay in 2016. This is a statistical study that analyses the relationship between the application of corporate volunteering activities and the incorporation of a CSR approach to the management of companies. The incorporation of both types of practices is measured by a self-assessment questionnaire that includes 81 indicators (using a Likert scale to assess them, which were designed based on ISO 26000 Guidance of Social Responsibility. The questionnaire was administered to 96 companies, using a comparative analysis between those that practice Corporate Volunteering and those which do not. The results obtained allow us to support the hypothesis that the application of Corporate Volunteering is positively associated with the incorporation of CSR when managing the relationship between the company and its employees and also with the community. Moreover, these results contribute to a better understanding on how both concepts are related.

    Full Text Available This paper presents an empirical investigation to study the relationship between social capital and organizational commitment. The study considers the relationship between social capital with three components of organizational commitment; namely, affective commitment, continuous and normative commitment. The study has been applied among a sample of 292 regular employees who worked for an Iranian bank located in city of Tehran, Iran. The implementation of Pearson correlation has indicated that there were positive and meaningful relationships between social capital and affective commitment (r = 0.197, Sig. = 0.01, continuous (r = 0.308, Sig. = 0.01 and normative commitment (r = 0.423, Sig. = 0.01. In addition, the study has detected that women had more commitment on their organization than men did. The proposed study of this paper has also considered a regression model where organizational commitment is dependent variable and trust and communication are considered as independent variables. According to the results of regression analysis, an increase of one unit in trust and social capital communication will increase organizational commitment by 0.189 and 0.204, respectively.

    Guerra, Maricela

    The Next Generation Science Standards (NGSS) advocated by the National Research Council emphasize the connections among Science, Technology, Engineering, and Mathematics (STEM) disciplines. By design, NGSS is expected to replace the previous science education standards to enhance the quality of STEM education across the nation. To support this initiative, this investigation was conducted to fill a void in the research literature by developing an empirical indicator for the relationship of student performance across STEM subjects using a large-scale database from the Trends in Mathematics and Science Study (TIMSS). In particular, an innovative approach has been taken in this study to support the canonical correlation analysis of student plausible scores between physics and other STEM subjects at different grade levels and in a cross-country context. Results from this doctoral research revealed the need to strengthen the alignment between the intended, implemented, and attained curricula to support the integration of STEM disciplines in the United States.

    In this study, we use dynamic panel data models to examine the impact of electricity and non-electricity variables on economic growth for a global panel consisting of 66 countries. The time component of our dataset is 1986-2005 inclusive. We also estimate this relationship for four regional panels; namely, East/South Asian and the Pacific region, Europe and Central Asian region, Latin America and Caribbean region, and Sub-Saharan, North Africa and Middle Eastern region. In total, we use six proxies for energy. The empirical analysis is based on a sound theoretical framework, in that we draw on growth theory and augment the classical growth model, which consists of inflation, capital stock, labour force and trade, with energy. Generally, the results on the impact of energy are mixed. (author)

    Soot aggregates (SAs)-fractal clusters of small, spherical carbonaceous monomers-modulate the incoming visible solar radiation and contribute significantly to climate forcing. Experimentalists and climate modelers typically assume a spherical morphology for SAs when computing their optical properties, causing significant errors. Here, we calculate the optical properties of freshly-generated (fractal dimension Df = 1.8) and aged (Df = 2.6) SAs at 550 nm wavelength using the numericallyexact superposition T-Matrix method. These properties were expressed as functions of equivalent aerosol diameters as measured by contemporary aerosol instruments. This work improves upon previous efforts wherein SA optical properties were computed as a function of monomer number, rendering them unusable in practical applications. Future research will address the sensitivity of variation in refractive index, fractal prefactor, and monomer overlap of SAs on the reported empirical relationships.

Such empirical study is necessary for investigating the possibility of determining terrain geomorphological parameters from bidirectional reflectance data. A new apparatus was developed to take accurate hemispherical directions radiance measurements (HDRM). A digitizer for three-dimensional in situ roughness measurements was also developed. More than 70 hemispherical data sets were collected for various illumination conditions and surface types of desert stony pavements and rocky terrain slopes. In general, it was found that most of the surfaces exhibited an anisotropic reflection, combining a major component of backscattering. The BRDF of different surface types in relation to their roughness properties as determined by the field digitizer were then examined. Results showed that sites that are considered to differ significantly from a geomorphological point of view would not necessarily form a different BRDF

    Phase change materials (PCM) used in thermal energy storage (TES) systems have been presented, over recent years, as one of the most effective options in energy storage. Paraffin and fatty acids are some of the most used PCM in TES systems, as they have high phase change enthalpy and in addition they do not present subcooling nor hysteresis and have proper cycling stability. The simulations and design of TES systems require the knowledge of the thermophysical properties of PCM. Thermal conductivity, viscosity, specific heat capacity (Cp) can be experimentally determined, but these are material and time consuming tasks. To avoid or to reduce them, and to have reliable data without the need of experimentation, thermal properties can be calculated by empirical equations. In this study, five different equations are given to calculate the viscosity and specific heat capacity of fatty acid PCM and paraffin PCM. Two of these equations concern, respectively, the empirical calculation of the viscosity and liquid Cp of the whole paraffin PCM family, while the other three equations presented are for the corresponding calculation of viscosity, solid Cp, liquid Cp of the whole fatty acid family of PCM. Therefore, this study summarize the work performed to obtain the main empirical equations to measure the above mentioned properties for whole fatty acid PCM family and whole paraffin PCM family. Moreover, empirical equations have been obtained to calculate these properties for other materials of these PCM groups and these empirical equations can be extrapolated for PCM with higher or lower phase change temperatures within a lower relative error 4%.

    In the field of γ-ray measurements, the determination of full energy (FE) absorption peak efficiency for a voluminous sample is difficult, because the preparation of the certified radiation source with the same chemical composition and geometry for the original voluminous sample is not easy. In order to solve this inconvenience, simulation or semi-empirical methods are preferred in many cases. Effective Solid Angle (ESA) Code which includes semi-empirical approach has been developed by the Applied Nuclear Physics Group in Seoul National University. In this study, we validated ESA code by using Marinelli type voluminous KRISS (Korea Research Institute of Standards and Science) CRM (Certified Reference Materials) sources and IAEA standard γ-ray point sources. And semi-empirically determined efficiency curve for voluminous source by using the ESA code is compared with the experimental value. We calculated the efficiency curve of voluminous source from the measured efficiency of standard point source by using the ESA code. We will carry out the ESA code validation by measurement of various CRM volume sources with detector of different efficiency.

    2017-03-01

    Full Text Available Cross-border e-commerce has been very successful in the last decade. Merchants and consumers have been encouraged to participate in e-commerce, including B2C or B2B. B2C is not limited to a domestic market anymore. Consumers across countries are interested in overseas direct purchases. They are willing to purchase products from major online shopping sites such as Amazon and eBay. We aim at gaining a better understanding of overseas direct purchases. Determinants of overseas direct purchases based on cross-national data are identified. Accordingly, we investigate logistics and regulatory determinants. Furthermore, external environments such as regulatory institutions and globalization are discussed in terms of overseas direct purchases. This study incorporates theoretical foundations into empirical findings. Specifically, the institutional theory and the resource-based view are applied to explain the internal and external determinants to increase overseas direct purchases. We conduct an empirical test using panel data for each country to identify the various determinants associated with overseas direct purchases.

    Full Text Available The study investigated relationships between agricultural policy output (proxy by the agricultural productivity index, agricultural GDP/total GDP and crop productivity index and output of industrial sector (proxy by the industrial capacity utilization rate from 1970 to 2012 period in Nigeria. The study employed time series variables obtained from the Central Bank of Nigeria (CBN, National Bureau of Statistics and Food and Agricultural Organization (FAO. Augmented Dickey-Fuller unit root test was conducted on the specified time series, and the result showed that all non-growth rate series were integrated of order one, while growth rate series were stationary at level. The two-step Engle Granger method was employed to test for the presence of cointegration among specified variables. The result revealed that variables were not co-integrated. To avoid spurious regression, the specified models for non-growth rate series were estimated at first difference of the log variables. The empirical result revealed that, the industrial activities Granger cause crop activities in Nigeria. Also, the industrial activity has insignificant relationship with agricultural productivity indices in Nigeria. The same result was also obtained for industrial activities and agricultural GDP/total GDP. However, the result further revealed that, the industrial activity has significant negative correlation with the crop productivity index in Nigeria. These imply that, agricultural production had not played significant role in industrial development in Nigeria. This result suggests that, there is no significant impact of the backward integration policy of the agricultural sector on industrial sector in Nigeria. In addition, the result revealed that, agricultural policies during liberalization era (1986 - 2012 shifted the coefficient of the industrial activities positively. Therefore, it is recommended that the agricultural production in Nigeria should be boosted so as to

    The personality trait of conscientiousness has seen considerable attention from applied psychologists due to its efficacy for predicting job performance across performance dimensions and occupations. However, recent theoretical and empirical developments have questioned the assumption that more conscientiousness always results in better job performance, suggesting a curvilinear link between the 2. Despite these developments, the results of studies directly testing the idea have been mixed. Here, we propose this link has been obscured by another pervasive assumption known as the dominance model of measurement: that higher scores on traditional personality measures always indicate higher levels of conscientiousness. Recent research suggests dominance models show inferior fit to personality test scores as compared to ideal point models that allow for curvilinear relationships between traits and scores. Using data from 2 different samples of job incumbents, we show the rank-order changes that result from using an ideal point model expose a curvilinear link between conscientiousness and job performance 100% of the time, whereas results using dominance models show mixed results, similar to the current state of the literature. Finally, with an independent cross-validation sample, we show that selection based on predicted performance using ideal point scores results in more favorable objective hiring outcomes. Implications for practice and future research are discussed.

    Solute transport studies in streams and rivers often begin with the introduction of conservative and reactive tracers into the water column. Information on the transport of these substances is then captured within tracer breakthrough curves (BTCs) and used to estimate, for instance, travel times and dissolved nutrient and carbon dynamics. Traditionally, these investigations have been limited to systems with small discharges (turbidity (e.g., nitrate signals with SUNA instruments or fluorescence measures) and/or high total dissolved solids (e.g., making prohibitively expensive the use of salt tracers such as NaCl) in larger systems. Additionally, a successful time-of-travel study is valuable for only a single discharge and river stage. We have developed a method to predict tracer BTCs to inform sampling frequencies at small and large stream orders using empirical relationships developed from multiple tracer injections spanning several orders of magnitude in discharge and reach length. This method was successfully tested in 1st to 8th order systems along the Middle Rio Grande River Basin in New Mexico, USA.

    Full Text Available Exporting goods and services play an important role on economy of developing countries. There are many countries in the world whose economy is solely based on exporting raw materials such as oil and gas. Many believe that countries cannot develop their economy as long as they rely on exporting one single group of raw materials. Therefore, there is a need to help other sectors of industries build good infrastructure for exporting diversified products. In this paper, we perform an empirical analysis to determine the critical success factors on exporting different goods. The results are analyzed using some statistical non-parametric methods and some useful guidelines are also suggested.

    Jefferson Lab uses feedback loops (less than 1 hertz update rate) to correct drifts in CEBAF's electron beam orbit and energy. Previous incarnations of these loops used response matrices that were computed by a numerical model of the machine. Jefferson Lab is transitioning this feedback system to use empirically determined response matrices whereby the software introduces small orbit or energy deviations using the loop's actuators and measures the system response with the loop's sensors. This method is in routine use for orbit correction. This paper will describe the orbit correction system and future plans to extend this method to energy correction

    Khan, S.U.; Azeem, M.I.

    2016-01-01

    The importance of intercultural challenges is recognized by both the practitioners and researchers in offshore software development outsourcing (OSDO) relationships. These challenges affect almost all the activities involved in offshore software development outsourcing relationships especially communication, mutual understanding, interpretation and decision making processes etc. which in turn leads to project failure. In our previous published study we identified, through systematic literature review (SLR), various intercultural challenges faced by vendors in OSDO relationship. The aim of this study was to validate these findings through industry practitioners and to identify its intensity as well as to identify any other intercultural challenges, faced by vendor organizations in OSDO relationships. We performed questionnaire surveys with 41 experts from different software companies. A seven point likert scale was used to determine the significance of each intercultural challenge. Our findings indicate that all the intercultural challenges are critical for OSDO vendors. We further analyzed these challenges based on different variables, such as company size, company type, expert's job/position etc. We have identified that there is no significant difference in the intercultural challenges based on company type and expert's experience level. We identified that language and language proficiency is the most commonly agreed and difference in social behavior is the most commonly disagreed intercultural challenge in the category of both sizes of company. Similarly language and language proficiency is the most commonly agreed challenge based on experts job positions. (author)

  20. DETERMINANT OF HOUSING RENTS IN URBAN ALBANIA: AN EMPIRICAL HEDONIC PRICE APPLICATION WITH NSA SURVEY DATA

    Directory of Open Access Journals (Sweden)

    Mustafa Kahveci

    2017-06-01

    Full Text Available As an immobile, durable and heterogonous good, each housing unit has a bundle of different characteristics. Hedonic price method, which depends on the consumer theory of the classical economics, implies that each characteristic of heterogeneous goods provides a different level of satisfaction or utility to the consumer, being widely accepted as a toolkit for estimating effects of these characteristics on prices and rents. HPM expresses housing prices as the function of structural characteristics, location characteristics, and neighborhood characteristics. Theory and empirical applications of the HPM, which have been used for more than 40 years in developed countries, due to the lack of suitable data related literature is limited in Albania. The aim of this paper is to analyze the relationship between housing rents and housing characteristics in urban Albania with micro database of Living Conditions and Income Survey 2012.

The results of our study have indicated that there is definitely a difference in parenting style among various members in terms of career concern, career curiosity and career confidence but such relationship does not exists in terms of career control. In addition, the study explains that people with permissive parenting style have less career concern, career curiosity and career confidence than those with permissive parenting style do.

  3. EVOLUTION OF THEORIES AND EMPIRICAL MODELS OF A RELATIONSHIP BETWEEN ECONOMIC GROWTH, SCIENCE AND INNOVATIONS (PART I

    Directory of Open Access Journals (Sweden)

    Kaneva M. A.

    2017-12-01

    Full Text Available This article is a first chapter of an analytical review of existing theoretical models of a relationship between economic growth / GRP and indicators of scientific development and innovation activities, as well as empirical approaches to testing this relationship. Aim of the paper is a systematization of existing approaches to modeling of economic growth geared by science and innovations. The novelty of the current review lies in the authors’ criteria of interconnectedness of theoretical and empirical studies in the systematization of a wide range of publications presented in a final table-scheme. In the first part of the article the authors discuss evolution of theoretical approaches, while the second chapter presents a time gap between theories and their empirical verification caused by the level of development of quantitative instruments such as econometric models. The results of this study can be used by researchers and graduate students for familiarization with current scientific approaches that manifest progress from theory to empirical verification of a relationship «economic growth-innovations» for improvement of different types of models in spatial econometrics. To apply these models to management practices the presented review could be supplemented with new criteria for classification of knowledge production functions and other theories about effect of science on economic growth.

  4. Determination of knock characteristics in spark ignition engines: an approach based on ensemble empirical mode decomposition

    Li, Ning; Liang, Caiping; Yang, Jianguo; Zhou, Rui

    2016-01-01

    Knock is one of the major constraints to improve the performance and thermal efficiency of spark ignition (SI) engines. It can also result in severe permanent engine damage under certain operating conditions. Based on the ensemble empirical mode decomposition (EEMD), this paper proposes a new approach to determine the knock characteristics in SI engines. By adding a uniformly distributed and finite white Gaussian noise, the EEMD can preserve signal continuity in different scales and therefore alleviates the mode-mixing problem occurring in the classic empirical mode decomposition (EMD). The feasibilities of applying the EEMD to detect the knock signatures of a test SI engine via the pressure signal measured from combustion chamber and the vibration signal measured from cylinder head are investigated. Experimental results show that the EEMD-based method is able to detect the knock signatures from both the pressure signal and vibration signal, even in initial stage of knock. Finally, by comparing the application results with those obtained by short-time Fourier transform (STFT), Wigner–Ville distribution (WVD) and discrete wavelet transform (DWT), the superiority of the EEMD method in determining knock characteristics is demonstrated.

    Potter, C. S.

    1997-01-01

    This study describes the use of satellite data to calibrate a new climate-vegetation greenness function for global change studies. We examined statistical relationships between annual climate indexes (temperature, precipitation, and surface radiation) and seasonal attributes of the AVHRR Normalized Difference Vegetation Index (NDVI) time series for the mid-1980s in order to refine our empirical understanding of intraannual patterns and global abiotic controls on natural vegetation dynamics. Multiple linear regression results using global l(sup o) gridded data sets suggest that three climate indexes: growing degree days, annual precipitation total, and an annual moisture index together can account to 70-80 percent of the variation in the NDVI seasonal extremes (maximum and minimum values) for the calibration year 1984. Inclusion of the same climate index values from the previous year explained no significant additional portion of the global scale variation in NDVI seasonal extremes. The monthly timing of NDVI extremes was closely associated with seasonal patterns in maximum and minimum temperature and rainfall, with lag times of 1 to 2 months. We separated well-drained areas from l(sup o) grid cells mapped as greater than 25 percent inundated coverage for estimation of both the magnitude and timing of seasonal NDVI maximum values. Predicted monthly NDVI, derived from our climate-based regression equations and Fourier smoothing algorithms, shows good agreement with observed NDVI at a series of ecosystem test locations from around the globe. Regions in which NDVI seasonal extremes were not accurately predicted are mainly high latitude ecosystems and other remote locations where climate station data are sparse.

    Frick, Ulrich; Irving, Hyacinth; Rehm, Jürgen

    2012-03-01

    To empirically determine the impact of the capacity to sustain social relationships on valuing health states. 68 clinical experts conducted a health state valuation exercise in five sites using pairwise comparison, ranking, and person trade-off as elicitation methods. 23,840 pairwise comparisons of a total of 379 health states were analyzed by conditional logistic regression. Social relationships had a clear monotonic association with perceived disability: the more limited the capacity to sustain social relationships, the more disabling the resulting health state valuations. The highest level of limitations with respect to social relationships was associated with slightly lower impact on health state valuations compared to the highest level of limitations in physical functioning. Social relationships showed an independent contribution to health state valuations and should be included in health state measures.

    2012-01-01

    Full Text Available One of the most important issues on revenue management in banking industries is the assignment of loan to customers. In fact, a big portion of banks' revenue is from loan assignment and choosing appropriate customers for loan assignment not only reduces the financial risk but also it can increase the revenue. In this study, we perform an empirical study to find out whether customers' financial statements could provide enough information about customers for loan assignment. The other objective of this study is to find out whether banks' officials could understand about the details of customers' financial statements. Finally, we want to find out whether there is any relationship between unpaid loans and customers' credit rating. The present study is executed on an Iranian bank by distributing a questionnaire analyzing the results. The results indicate that there are some strong evidence that financial statement could help bank official determine customers' credit rating. The survey also concludes that highly education and experienced employees are the best people for devoting best credit rating for customers.

  9. Mapping sediment thickness of Islamabad city using empirical relationships: Implications for seismic hazard assessment

    Science.gov (United States)

    Khan, Sarfraz; Khan, M. Asif

    2016-04-01

    Soft sediments make an important component of the subsurface lithology, especially in areas underlain by river/stream basins. Occupying a position directly above the bedrock up to the land surface, these soft sediments can range in thickness from few centimeters to hundreds of meters. They carry a special nuisance in seismic hazards, as they serve as a source of seismic amplification that may enhance the seismic shaking of many folds. Determination of the thickness of the soft sediments is therefore crucial in seismic hazard analysis. A number of studies in recent years have demonstrated that frequency and amplitude spectrum obtained from the noise measurements during the recording of natural seismicity can be used to obtain thickness of soft sediments covering the bedrock. Nakamura (1989) presented a technique to determine such spectrum using ratio of horizontal to vertical components of the Rayleigh waves. The present study is based on an extensive set of microtremor measurements carried out in the Islamabad city, Pakistan. Fundamental frequencies were obtained from weak motion sensors and Tromino Engy Plus instruments to show that the correlation is clearly valid for a wide range of sediment thickness. A simple formula was derived for the investigated area to determine directly the thickness of sediments from the main peaks in the H/ V spectrum for seismometer and Tromino data separately. A comparison is made between sediment thicknesses derived from empirical relations developed in this study with those given in literature to demonstrate a positive correlation. The correlation of instrumental resonant frequencies with calculated resonant frequencies (theoretical) suggests that the relation derived from the noise measurements mostly depends on the velocity depth function of the shear wave. The fundamental frequency of the main peak of spectral ratio of H/ V using the both instruments correlates well with the thickness of sediments at the site obtained from the

    2016-01-01

    Medicines are an important part of household health spending. A progressive system for financing drugs is thus essential for an equitable health system. Some authors have proposed that the determinants of equity in drug financing are socioeconomic, demographic, and associated with public interventions, but little progress has been made in the empirical evaluation and quantification of their relative importance. The current study estimated quantile regressions at the provincial level in Argentina and found that old age (> 65 years), unemployment, the existence of a public pharmaceutical laboratory, treatment transfers, and a health system orientated to primary care were important predictors of progressive payment schemes. Low income, weak institutions, and insufficient infrastructure and services were associated with the most regressive social responses to health needs, thereby aggravating living conditions and limiting development opportunities.

    Full Text Available Orthodox economists generally think about labor market that the price stability and low unemployment cannot be achieved at the same time. In this sense, the Orthodox argument discusses that a decline in the aggregate demand will decrease the money wages and real wages proportionally, and increase the volume of employment. Michal Kalecki denies such a wage policy which is consistently determined by this idea. Wages reflect the price-money wage relation in real terms. Prices set in regard to the degree of monopoly. In this context, it is assumed real wages is determined depending upon the degree of monopoly, labor productivity and price of import goods. According to Kalecki, Orthodoxian view which relates a decrease in real wages with an increase in production based on increasing marginal cost assumption and Kalecki does not accept this perspective. Kaleckian PostKeynesian labor market will be theoretically discussed and the determination process of the real wage will be empirically analyzed for Turkish economy over the period 1989:1 to 2012:4.

  13. An empirical determination of the production efficiency for auroral 6300 AA emmission by energetic electrons

    Auroral data from the Soft Particle Spectrometer and the Red Line Photometer on the ISIS-2 spacecraft have been selected to form an electron energy flux and optical auroral emission data base. The energy fluxes are stored as integrated fluxes over four energy bands, and the corresponding stored optical emission rates are corrected for airglow and for albedo. Because of the variety of electron energy spectra represented in the data base it was possible to perform a regression analysis that yielded the production efficiency for the production of emission for each of the four bands. While the results of this analysis are interesting to compare with theoretical predictions of 6300 AA excitation processes, these statistical results are not as precise as the comparisons of individual experiments where all parameters, such as the atmospheric composition and temperature profiles are measured. The significance of this approach is that it permits a multiparameter description of an electron energy spectrum, and its relationship to a specific optical emission, by purely empirical means. This is particularly useful in the interpretation of ISIS-2 data from the instruments which provided the results, but should find further application in optical-particle auroral studies. (author)

  14. Uncertainty in Measurement: A Review of Monte Carlo Simulation Using Microsoft Excel for the Calculation of Uncertainties Through Functional Relationships, Including Uncertainties in Empirically Derived Constants

    2014-01-01

    The Guide to the Expression of Uncertainty in Measurement (usually referred to as the GUM) provides the basic framework for evaluating uncertainty in measurement. The GUM however does not always provide clearly identifiable procedures suitable for medical laboratory applications, particularly when internal quality control (IQC) is used to derive most of the uncertainty estimates. The GUM modelling approach requires advanced mathematical skills for many of its procedures, but Monte Carlo simulation (MCS) can be used as an alternative for many medical laboratory applications. In particular, calculations for determining how uncertainties in the input quantities to a functional relationship propagate through to the output can be accomplished using a readily available spreadsheet such as Microsoft Excel. The MCS procedure uses algorithmically generated pseudo-random numbers which are then forced to follow a prescribed probability distribution. When IQC data provide the uncertainty estimates the normal (Gaussian) distribution is generally considered appropriate, but MCS is by no means restricted to this particular case. With input variations simulated by random numbers, the functional relationship then provides the corresponding variations in the output in a manner which also provides its probability distribution. The MCS procedure thus provides output uncertainty estimates without the need for the differential equations associated with GUM modelling. The aim of this article is to demonstrate the ease with which Microsoft Excel (or a similar spreadsheet) can be used to provide an uncertainty estimate for measurands derived through a functional relationship. In addition, we also consider the relatively common situation where an empirically derived formula includes one or more ‘constants’, each of which has an empirically derived numerical value. Such empirically derived ‘constants’ must also have associated uncertainties which propagate through the functional

    2004-01-01

    This paper presents empirical evidence on the determinants of water demand for domestic use in one Italian region, the Emilia Romagna, by using municipal data. Two main stems in urban/domestic demand analysis cab be found in the empirical literature. The first deals with the estimation of price or income demand elasticities in the short and the long run. The price demand elasticities can be used for water demand managements purpose while the income price elasticities can be useful in the forecasting process of the water requirements. The second one deals with the estimate of customer willingness to pay increasing in water service quality in holistic sense or concerning single characteristics of the service: safety, flavour, continuity, appearance, pollution rate and cost. The aim of the analysis in this case the elicitation of the direct use, indirect use and non-use values associated to the water resource consumption, by means of direct or indirect techniques. In this paper we focused the analysis in the first stem of the empirical literature in which a cross section data set is required. The paper explores the topic problems of the estimating process whit the analysis of the empirical literature (with particular regard to investigations that use municipal data) and with the analysis of the econometric problems related to the demand estimate. The theoretical model for the water demand analysis is also presented and discussed. Two datasets have been implemented: one with 125 municipalities and four years, the other with 40 municipalities and eleven years. Both the databases bring together municipal water consumption and tariffs data provided by local water utilities and other municipal data (inhabitants, surface, household, income, etc.) stemming from official sources. The econometric analysis is based on both fixed effects, performing better than random effects models, and dynamic panel models. The estimated coefficient of the tariff variable arises always

    2017-04-01

    Full Text Available This study reviewed literature studies on the determinants of government expenditure for the period 1995 to 2016. The research for the studies was conducted on the internet by combining government expenditure and determinants such as economic growth, government revenue, trade openness, poverty, public debt, dependency ratio, population, and urbanisation on the search engine. The finding of the literature provides conflicting results concerning the determinants of government expenditure. The results indicate that the government expenditure relationship with its determinants is significantly positive but in some instances it was found to be negative. The study recommends that future studies use the newly developed econometric techniques on previous studies to see whether they can provide different results.

  1. Experimental Evidence that Social Relationships Determine Individual Foraging Behavior.

    Science.gov (United States)

    Firth, Josh A; Voelkl, Bernhard; Farine, Damien R; Sheldon, Ben C

    2015-12-07

    Social relationships are fundamental to animals living in complex societies. The extent to which individuals base their decisions around their key social relationships, and the consequences this has on their behavior and broader population level processes, remains unknown. Using a novel experiment that controlled where individual wild birds (great tits, Parus major) could access food, we restricted mated pairs from being allowed to forage at the same locations. This introduced a conflict for pair members between maintaining social relationships and accessing resources. We show that individuals reduce their own access to food in order to sustain their relationships and that individual foraging activity was strongly influenced by their key social counterparts. By affecting where individuals go, social relationships determined which conspecifics they encountered and consequently shaped their other social associations. Hence, while resource distribution can determine individuals' spatial and social environment, we illustrate how key social relationships themselves can govern broader social structure. Finally, social relationships also influenced the development of social foraging strategies. In response to forgoing access to resources, maintaining pair bonds led individuals to develop a flexible "scrounging" strategy, particularly by scrounging from their pair mate. This suggests that behavioral plasticity can develop to ameliorate conflicts between social relationships and other demands. Together, these results illustrate the importance of considering social relationships for explaining behavioral variation due to their significant impact on individual behavior and demonstrate the consequences of key relationships for wider processes.

According to the analysis, the dependent variable with a significant level of research and positive leadership style has been determined that no relationships. Regression analysis revealed that the leadership of the relationship with the creative problem-solving capacity of democratic leadership in style when found to be stronger than other leadership styles, while the variable describing the career of the employee satisfaction level of the maximum it was concluded that the creative problem-solving capacity of the organization. Research in the context of human resources on the very important for organizations, leadership behavior, creative problem-solving capacity and career satisfaction studies analyzing the relationships between variables it seems to be quite limited. The discovery by analyzing the relationship between the aforementioned variables, can make significant contributions to knowledge in the literature and are expected to form the basis for future research.

  4. Some Empirical Aspects regarding the Relationship between Inflation and Economic Growth in Romania – the Speed Limit Effect

    2011-12-01

    Full Text Available This study briefly presents theoretical aspects related to the relationship between inflation and economic growth and provides an empirical study for the Romanian economy, for the period 2000 – 2011. The econometric methodology used is that of vector auto-regressions.The results showed that a sudden increase in the change of the output gap (i.e. a shock to the growth rate of the output gap does not determine an increase in CPI. Hence, the hypothesis of the existence of a speed limit effect in Romania is rejected. In concrete terms, this means that the monetary authorities should not fear for eventual inflationary pressures when sudden increases of demand arise, if the output gap is negative (the potential output is higher that the effective output. The National Bank of Romania may avoid, therefore, taking some monetary policy decisions meant to temper the rise in inflation (as would have been the case if a speed limit effect was present but which would have induced unnecessary volatility into the output. However, the study indicates that National Bank of Romania should communicate to the public the state of the economy in order to timely anchor the inflation expectations. This is a very important aspect, since the inflation expectations firmly react to a shock into the growth rate of the output gap, i.e. to a strong increase in the effective output.The study also showed a positive response of the growth rate of the output gap to a positive shock in inflation, with a maximum effect after three quarters. This shows that the inflation was mainly driven by demand factors in the analysed period, with the consumers increasing current consumption in order to avoid the future higher prices and with the economic agents increasing the supply such as to maximise the unitary profits. Also, this result shows a rather inelastic demand or a possible captivity of consumers in the face of producers.

    Full Text Available In today’s dynamic business environment, firms are required to utilize efficiently and effectively all the useful resources to gain competitive advantage. Supplier development has evolved as an important strategic instrument to improve buyer supplier relationships. For that reason, this study focuses on providing the strategic significance of supplier development approaches to improve business relationships. By using qualitative research method, an integrated framework of supplier development and buyer-supplier relationship development has been tested and validated in a Finnish case company to provide empirical evidence. It particularly investigates how supplier development approaches can develop buyer-supplier relationships. The study present a set of propositions that identify significant supplier development approaches critical for the development of buyer-supplier relationships and develop a theoretical framework that specifies how these different supplier development approaches support in order to strengthen the relationships. The results are produced from an in-depth case study by implementing the proposed research framework. The findings reveal that supplier development strategies i.e., supplier incentives and direct involvements strongly effect in developing buyer-supplier relationships. Further research may focus on considering in-depth investigation of trust and communication factors along with propositions developed in the study to find out general applicability in dynamic business environment. Proposed integrated framework along with propositions is a unique combination of useful solutions for tactical and strategic management’s decision making and also valid for academic researchers to develop supplier development theories.

    Full Text Available As the second largest producer of cement after Egypt in the Middle East, Iran planned to increase production from 33 million ton/yr (Mt/yr currently to 70 Mt/yr by 2021 due to increase in local demand and also to compete in export markets (Dehqan, 2002. Thus, Iran is experiencing some changes in workforce participation in order to achieve high level of organisational performance and effectiveness. The objective of this study is to determine the impact of leadership behavior and perceived organisational support on the job satisfaction of Iranian employees. Data were collected through questionnaire from 136 employees working in Tehran Cement Company. Consideration leadership behavior was found to have significant impact on both intrinsic and extrinsic job satisfaction whereas perceived organisational support was significantly related to extrinsic job satisfaction. Interestingly, the interaction of leadership behavior and perceived organisational support were not significantly related to job satisfaction. The implications to human resource development for organizations that want to increase employee commitment is to focus on improving the quality of the supportive relationships between the employees and both the leader and the organisation.

    Full Text Available The empirical study over the period 1978-2011 found that the relationship between real per capita GDP and financial interrelation ratio structurally broke since 2004. From 1978 to 2003, economic growth and financial development had a long-term co-integration, and it showed one-way supply relationship according to the Granger causality test, which means the economic growth have a slowly leading function to the development of finance. From 2004 to 2011, the correlation between them became weaker and had no Granger causality, but there had a long-term co-integration and mutual causality relationship existed between loan and GDP during the whole period. From it we can see loan could boost output more persistently. Therefore, the enhanced economic power of Jiangxi province could promote further development of regional financial service industries, and we would propose some related policy suggestions in this paper.

    2013-03-01

    Full Text Available Effective supplier-buyer relationship management should not be seen only in terms of cost and financial measures, as outlined by Transaction cost economics, but also in terms of other (“softer” relational benefits, like e.g. more comprehensive information sharing, higher levels of trust, better cooperation and increased relationship flexibility. This second view is grounded in both Relationship marketing and Resource-advantage theory. Surprisingly, only a few research papers on supplier-buyer relationships address both of these perspectives equally, as well as in terms of long-term competitiveness (vis-avis a traditional short-term performance. The purpose of this paper is to analyze business relationship determinants of supplier-buyer relationship competitiveness, where we study the impact of (1 relationship-based information exchange, (2 network spillover effects, (3 transaction-specific investments, (4 trust, (5 cooperation (joint actions and (6 flexibility on perceived (7 supplier-buyer relationship competitiveness. In this regard the main research question of our study is: Which relational and transactional dimensions determine supplier-buyer relationship competitiveness, as well as how strongly? To provide the answer this research question we employ an exploratory-type Partial Least Squares (PLS regression in conjunction with a novel perspective of network spillover effects, as a set of independent variables in our model. The data set consists of a sample of 130 international suppliers (approx. 30 % response rate connected to a transnational company (TNC headquartered in Slovenia, which operates in the steel construction solutions’ industry. Our results clearly identify a relational and a transactional set of determinants of supplier-buyer relationship competitiveness, with the former having a significantly higher impact on competitiveness than the latter.

    Full Text Available The aim of this paper is the detection and analysis of empirical determinants of credit risk in the banking sector of the Republic of Serbia. The paper is based on an analysis of results of the application of the linear regression model, during the period from the third quarter of 2008 to the third quarter of 2014. There are three main findings. Firstly, the higher lending activity of banks contributes to the increasing share of high-risk loans in the total withdrawn loans (delayed effect of 3 years. Secondly, the growth of loans as opposed to deposits contributes to the increased exposure of banks to credit risk. Thirdly, the factors that reduce the exposure of banks to credit risk increase profitability, growth of interest rate spread and real GDP growth. Bearing in mind the overall market conditions and dynamics of the economic recovery of the country, there is a general conclusion based on the results that in the coming period the question of non-performing loans (NPLs in the Republic of Serbia will present a challenge for both lenders and borrowers.

    Full Text Available Nowadays, establishing long-term and effective relationships with customers is a key factor in understanding customers’ needs and preferences and achieving competitive advantage. In addition, companies are facing with a growing need for information and analytical knowledge about their customers, market, competitors, organizational environment, and other factors affecting their business. Business intelligence has been considered as a response to this need. The purpose of this study is to investigate the role of business intelligence competence in improving customer relationship management process. Based on the literature review and the competence – capability relationship paradigm, a conceptual model was developed comprising of different dimensions of business intelligence competence and customer relationship management processes. The data were collected from the banking sector and partial least squares structural equation modelling was employed for data analysis. Empirical results showed that organizational business intelligence competence, comprising of managerial, technical, and cultural competence, has a significantly positive impact on enhancing capabilities of customer relationship management process including initiation, maintenance, and termination of the relationship.

    Full Text Available Purpose: Previous studies have been employing SERVQUAL by Parasuraman et al. (1985, 1988 to measure service quality in various service sectors due to its generic nature. Understanding the relationship between service quality and customer’s perceived value in non-business organizational settings is equally important with business setting as positive perception leads to favorable outcome. Hence, the aim of this study is to examine the relationship between service quality and perceived value. Design/methodology/approach: The self-administered survey questionnaires were employed to gather data from Malaysian soldiers who involved in peacekeeping mission at a Middle Eastern country. The hypothesized model was analyzed using the SmartPLS 2.0. Findings: The outcomes of SmartPLS path model confirmed that that all service quality dimensions namely tangible, responsiveness, reliability, assurance, empathy did act as important determinants of customer’s perceived value in the organizational sample. Practical implications: The findings of this study may be used as guidelines by practitioners to formulate relevant and appropriate strategies in order to enhance quality of service delivery in agile organizations. Originality/value: The work deals with service quality in non-business setting. Although the scale has been widely used, some modifications are generally needed in order to reflect specific characteristics of service sectors under study. The findings confirmed that in general SERVQUAL five dimensions are important determinants to the various service sectors.

    1979-01-01

    A semiempirical formula is developed for describing the extent of interaction between constituents in single-phase binary alloy systems with planar, cylindrical, or spherical interfaces. The formula contains two parameters that are functions of mean concentration and interface geometry of the couple. The empirical solution is simple, easy to use, and does not involve sequential calculations, thereby allowing quick estimation of the extent of interactions without lengthy calculations. Results obtained with this formula are in good agreement with those from a finite-difference analysis.

    Full Text Available This study examines the empirical link between three dimensions of market orientation, namely, stu­dent orientation, competitor orientation and inter-functional coordination, and overall private uni­ver­sity per­formance in Kopertis X. It was based on an empirical investigation of private universities located in In­do­nesia’s provinces of West Sumatera, Riau, Jambi, and Kepulauan Riau. The primary data for the study were collected from a self-administered mail survey of 237 questionnaires from the private university re­sul­­ting in a sample of 114 usable responses being returned. From the application of the multiple re­gres­sion ana­lysis it was concluded that all three dimensions of market orientation had a significant impact on private un­iversity performance. Student orientation as a predictor variable is the strongest predictor of pri­vate uni­ver­­sity performance and followed by competitor orientation, and inter-functional coordination.

    The aim of the study was to assess the applicability of asymptotic functions for determining the value of CN parameter as a function of precipitation depth in mountain and upland catchments. The analyses were carried out in two catchments: the Rudawa, left tributary of the Vistula, and the Kamienica, right tributary of the Dunajec. The input material included data on precipitation and flows for a multi-year period 1980-2012, obtained from IMGW PIB in Warsaw. Two models were used to determine empirical values of CNobs parameter as a function of precipitation depth: standard Hawkins model and 2-CN model allowing for a heterogeneous nature of a catchment area. The study analyses confirmed that asymptotic functions properly described P-CNobs relationship for the entire range of precipitation variability. In the case of high rainfalls, CNobs remained above or below the commonly accepted average antecedent moisture conditions AMCII. The study calculations indicated that the runoff amount calculated according to the original SCS-CN method might be underestimated, and this could adversely affect the values of design flows required for the design of hydraulic engineering projects. In catchments with heterogeneous land cover, the results of CNobs were more accurate when 2-CN model was used instead of the standard Hawkins model. 2-CN model is more precise in accounting for differences in runoff formation depending on retention capacity of the substrate. It was also demonstrated that the commonly accepted initial abstraction coefficient λ = 0.20 yielded too big initial loss of precipitation in the analyzed catchments and, therefore, the computed direct runoff was underestimated. The best results were obtained for λ = 0.05.

    Full Text Available Urbanization results in habitat loss and habitat fragmentation concurrently, both influencing biodiversity and ecological processes. To evaluate these impacts, it is important to understand the relationships between habitat loss and habitat fragmentation per se (HLHF during urbanization. The objectives of this study were two-fold: 1 to quantify the different forms of the HLHF relationship during urbanization using multiple landscape metrics, and 2 to test the validity of the HLHF relations reported in the literature. Our analysis was based on a long-term urbanization dataset (1800-2000 of 16 large cities from around the world. Habitat area was represented as the percentage of non-built-up area in the landscape, while habitat fragmentation was measured using several landscape metrics. Our results show that the relationship between habitat loss and habitat fragmentation during urbanization is commonly monotonic-linear, exponential, or logarithmic, indicating that the degree of habitat fragmentation per se increases with habitat loss in general. We compared our results with 14 hypothesized HLHF relationships based on simulated landscapes found in the literature, and found that four of them were consistent with those of urbanization, whereas the other ten were not. Also, we identified six new HLHF relationships when fragmentation was measured by total core area, normalized total core area, patch density, edge density and landscape shape index, respectively. In addition, our study demonstrated that the "space-for-time" approach, frequently used in ecology and geography, generated specious HLHF relationships, suggesting that this approach is largely inappropriate for analyses of urban landscapes that are highly heterogeneous in space and unusually contingent in dynamics. Our results show both generalities and idiosyncrasies of the HLHF relationship, providing new insights for assessing ecological effects of urbanization.

    Full Text Available The purpose of this research is to develop cost-effectiveness tools for the analysis of company’s intellectual resources, in terms of resource-based and value-based approaches. Our study focuses on the evaluation of intellectual capital methods to discover the drivers of company growth. We suppose that the potential effectiveness of intellectual capital resources varies according to different institutional factors. Several statistical methods will be used for the empirical issues in this research, including common cross-sectional and panel data analysis, and the instrumental variables method. The database collected for this purpose will consist of financial and economic indicators underlying the intellectual capital evaluation, such as strategic performance indicators (EVA© and FGV©. The dataset includes companies from different countries and industries according to the Knowledge Economy Index of the World Bank. The industries presented in the dataset are selected according to the predominance of several intellectual capital elements. The database includes financial services, wholesale and retail trade, machinery and equipment manufacture, the chemical industry, and transport and communications. As a result of the empirical research, we expect to answer the following questions: • Is there a close relationship between intellectual capital quality and company performance? • What are the external and internal factors affecting this relationship? (country, industry, company size, market dynamics, etc.

    Full Text Available This paper provides evidence on the impact of the change in income tax rates and the degree of its progressivity on the scale of labour taxes evasion in Serbia, using the tax-benefit microsimulation model and econometric methods, on 2007 Living Standard Measurement Survey data. The empirical analysis is based on novel assumption that individual's tax evasion decision depends on a change in disposable income, which is captured by the variation in their Effective Marginal Tax Rates (EMTR, rather than on a change in after-tax income. The results suggest that the elasticity of tax evasion to EMTR equals -0.3, confirming the Yitzhaki's theory, while the propensity to evade is decreasing in the level of wages and increasing in the level of self-employment income. The results also show that introduction of revenue-neutral, progressive taxation of labour income would lead to increase in labour tax evasion by 1 percentage point.

    Full Text Available Intellectual capital (IC is normally used to create value for organizations and in today's business environment; the success of each organization depends on managing such assets. During the past few years, many organizations implement IC to increase their competitive advantages. Hospitals are among business units where IC plays an important role on the success of these units. People normally choose hospitals based not only based on their equipments but also based on the specialists and physicians they have. In this paper, we present an empirical study to measure the impact of IC in accounting parts of hospitals. The results of our regression analysis indicates that when there is a unit increase in either of human, customer, structural or intellectual capital individually, we can expect of an increase of 1.278, 1.210, 1.415 and 1.620 units increase in the performance of the university, respectively.

    Full Text Available The objective of this paper is to assess the main determinants and the policies that affect economic growth in the Western Balkan over the period 1994 to 2015. It employs techniques such as pooled OLS, fixed and random effects model, and Hausman-Taylor model with instrumental variables (IV. The study shows evidence of conditional convergence, indicating the need for an upward move in the steady state level. The results show that foreign direct investments, gross savings and domestic credit to the private sector have a positive effect on per capita growth. On the other hand, initial level of per capita growth, corruption, unemployment, and general government final consumption, have a negative relationship with per capita growth. The study also shows a puzzling result, that schooling is not a significant factor for growth in Western Balkans. The study also highlights the relevance of attracting more foreign direct investments and reduction in corruption.

    This study is focused on the concept of company competitiveness, on the relevant factors in order to analyze and explain the advantage of competitiveness for a company in regard to another, as well as the dimension and intensity which it uses the sponsors’ capital, the organizational capital, the human capital, the innovational capital and the capital represented by the customers portfolio. Secondly, using the questionnaire method as a research method, the objective of this paper is to provide some empirical evidences designed to assess the factors determining the Romanian company competitiveness on the competitive market. By using an initial dataset of 300 companies, which are part of the 14 fields of activity provided in the activity classification of the national economy, Reviewed NACE 2, we have made their classification on size classes, taking into account as classification criteria the number of employees, the annual net turnover and the value of the total assets held, then testing the opinions of the managers from the selected sample concerning the factors determining the competitiveness of the companies they manage. According to the results, the analysis of the sample structure reflects the control of microenterprises followed by the small and medium sized enterprises. The manner of administration and organization and the quality of the employed human factor are influenced by the company dimension and position held on the market. We consider that the managers of the small size companies, as well as the ones from the provided sample, rely on a preponderant intuitive management, they deal the administered businesses based on the spur of the moment inspiration, make decisions subjectively not starting from objective economic criteria, being concerned only with the management of the current problems. Since they aren’t the beneficiaries of a managerial education, they don’t possess the necessary competences to focus on the elaboration of certain strategies

    It has been suggested that the relationship between income and the associated environmental pressure in terms of derived materials inputs and pollution levels may take an inverted-U shape, indicating a 'delinking' of environmental pressure from economic growth in relation to rising per capita incomes. The likelihood of such a relationship being persistent is discussed in the context of a simple macro model of industrial metabolism, and the possibility of 'relinking' clearly emerges. Data on specific indicators of environmental pressure (i.e., the throughput of materials, energy and the volume of transport) in 19 countries have been used to investigate patterns of delinking. The results suggest that delinking may not be persistent; already some advanced economies may be entering a new period of relinking. The relationships between environmental pressure and welfare in the medium long term may be N-shaped rather than inverted-U-shaped

    Following several decades of rapid economic growth, China has become the largest energy consumer and the greatest emitter of CO2 in the world. Given the complex development situation faced by contemporary China, Chinese policymakers now confront the dual challenge of reducing energy use while continuing to foster economic growth. This study posits that a better understanding of the relationship between economic growth, energy consumption, and CO2 emissions is necessary, in order for the Chinese government to develop the energy saving and emission reduction strategies for addressing the impacts of climate change. This paper investigates the cointegrating, temporally dynamic, and casual relationships that exist between economic growth, energy consumption, and CO2 emissions in China, using data for the period 1990-2012. The study develops a comprehensive conceptual framework in order to perform this analysis. The results of cointegration tests suggest the existence of long-run cointegrating relationship among the variables, albeit with short dynamic adjustment mechanisms, indicating that the proportion of disequilibrium errors that can be adjusted in the next period will account for only a fraction of the changes. Further, impulse response analysis (which describes the reaction of any variable as a function of time in response to external shocks) found that the impact of a shock in CO2 emissions on economic growth or energy consumption was only marginally significant. Finally, Granger casual relationships were found to exist between economic growth, energy consumption, and CO2 emissions; specifically, a bi-directional causal relationship between economic growth and energy consumption was identified, and a unidirectional causal relationship was found to exist from energy consumption to CO2 emissions. The findings have significant implications for both academics and practitioners, warning of the need to develop and implement long-term energy and economic policies in

    Understanding the relationships between extreme daily and sub-daily rainfall events and their governing factors is important in order to analyse the properties of extreme rainfall events in a changing climate. Atmospheric temperature is one of the dominant climate variables which has a strong relationship with extreme rainfall events. In this study, a temperature-rainfall binning technique is used to evaluate the dependency of extreme rainfall on daily maximum temperature. The Clausius-Clapeyron (C-C) relation was found to describe the relationship between daily maximum temperature and a range of rainfall durations from 6 min up to 24 h for seven Australian weather stations, the stations being located in Adelaide, Brisbane, Canberra, Darwin, Melbourne, Perth and Sydney. The analysis shows that the rainfall - temperature scaling varies with location, temperature and rainfall duration. The Darwin Airport station shows a negative scaling relationship, while the other six stations show a positive relationship. To identify the trend in scaling relationship over time the same analysis is conducted using data covering 10 year periods. Results indicate that the dependency of extreme rainfall on temperature also varies with the analysis period. Further, this dependency shows an increasing trend for more extreme short duration rainfall and a decreasing trend for average long duration rainfall events at most stations. Seasonal variations of the scale changing trends were analysed by categorizing the summer and autumn seasons in one group and the winter and spring seasons in another group. Most of 99th percentile of 6 min, 1 h and 24 h rain durations at Perth, Melbourne and Sydney stations show increasing trend for both groups while Adelaide and Darwin show decreasing trend. Furthermore, majority of scaling trend of 50th percentile are decreasing for both groups.

    Full Text Available Nowadays, any business manager is concerned about sustainability issues and is wondering how to implement social and environmental practices creating economic and social value at the same time. The implementation of social responsibility programs is justified by the benefits that result from a good relationship of the firm with key stakeholders. The present research investigates the links among firms’ relationship with stakeholders, firms’ champion behavior, stakeholders’ satisfaction and firms’ competitive success in regional contexts where social responsibility is promoted. Using the resource-based theory and the concept of shared value, a conceptual model is proposed in which a strong firm relationship with stakeholders will cause the stakeholder’ satisfaction and will help the firm to become a champion in the market, contributing to improved competitiveness. This empirical analysis was based on survey data through partial least squares structural equation modeling (PLS-SEM from 130 Spanish firms in the Region of Extremadura. Participants were firm managers in regional clusters involved in the social responsibility journey promoted by the local government. The results suggest that a good relationship of the frim with stakeholders directly and positively influences firm competitive success, and also, it is enhanced by improvements in stakeholders’ satisfaction and firm champion behavior.

    2017-10-01

    Full Text Available In this paper we explore whether a number of elements influence the levels of corporate social responsibility (CSR disclosure in the annual reports of Polish companies. These elements include the following: company size, profitability, financial leverage, industry environmental sensitivity, board size, women on the board, internationalization, and reputation. We use content analysis to determine the quality of CSR disclosures. We test our hypotheses using a Tobit regression analysis on a sample of 60 reports from Polish companies listed on the Warsaw Stock Exchange. We find industry environmental sensitivity to have significant influence on CSR disclosures. Our research findings also reveal a relationship between company turnover, duration of the stock exchange listing, inclusion in the Respect Index portfolio and foreign capital share, and the level of CSR disclosures. This study extends the scope of previous studies by including non-commonly used independent variables: the company’s internationalization and reputation. To the authors’ knowledge, it is the primary step to investigating CSR reporting practices coupled with the corporate characteristics in a Central and Eastern European country such as Poland. The paper contributes to the understanding of determinants of CSR disclosure and offers findings which are potentially useful for both theory and practice.

  9. Empirical Relationships Among Magnitude and Surface Rupture Characteristics of Strike-Slip Faults: Effect of Fault (System) Geometry and Observation Location, Dervided From Numerical Modeling

    2007-12-01

    In order to determine the magnitude of pre-historic earthquakes, surface rupture length, average and maximum surface displacement are utilized, assuming that an earthquake of a specific size will cause surface features of correlated size. The well known Wells and Coppersmith (1994) paper and other studies defined empirical relationships between these and other parameters, based on historic events with independently known magnitude and rupture characteristics. However, these relationships show relatively large standard deviations and they are based only on a small number of events. To improve these first-order empirical relationships, the observation location relative to the rupture extent within the regional tectonic framework should be accounted for. This however cannot be done based on natural seismicity because of the limited size of datasets on large earthquakes. We have developed the numerical model FIMozFric, based on derivations by Okada (1992) to create synthetic seismic records for a given fault or fault system under the influence of either slip- or stress boundary conditions. Our model features A) the introduction of an upper and lower aseismic zone, B) a simple Coulomb friction law, C) bulk parameters simulating fault heterogeneity, and D) a fault interaction algorithm handling the large number of fault patches (typically 5,000-10,000). The joint implementation of these features produces well behaved synthetic seismic catalogs and realistic relationships among magnitude and surface rupture characteristics which are well within the error of the results by Wells and Coppersmith (1994). Furthermore, we use the synthetic seismic records to show that the relationships between magntiude and rupture characteristics are a function of the observation location within the regional tectonic framework. The model presented here can to provide paleoseismologists with a tool to improve magnitude estimates from surface rupture characteristics, by incorporating the

    Full Text Available This paper investigates the behavior of the country risk premium for Argentina, Brazil and Mexico, from June 1997 to September 1998. It shows that the level of country risk premium is determined by different factors: the US dollar bond market structure; restrictions on the acquisition of emerging market bonds imposed by developed nations regulators; the credit risk measured by the notion of implied risk-neutral probability default; the different ways agents react to country risk due to asymmetric and imperfect information. The empirical investigation shows: the worse the country credit rating, the greater is the impact on international borrowing cost, which implies that negative expectations have greater impact on lower rated Latin American nations' bonds; country risk yield spreads overreacted to changes in the US dollar interest rates in the sample period.Este artigo investiga o comportamento do conceito de prêmio de risco-país para Argentina, Brasil e México, de junho de 1997 até setembro de 1998. Mostra-se que tal prêmio é determinado pelos seguintes fatores: a estrutura do mercado de títulos de dívida em dólares norte-americanos; as restrições à aquisição de títulos de dívida impostas por agentes reguladores de países desenvolvidos; o risco de crédito mensurado pelo conceito de probabilidade de inadimplência risco-nêutra implícita; o modo como os agentes reagem à informação assimétrica ou imperfeita. A evidência empírica revela que: quanto pior a classificação de risco de crédito, maior é o impacto esperado sobre as condições de captação externa, implicando que expectativas desfavoráveis afetam de forma mais acentuada países com baixa classificação de crédito; o valor do spread representativo do risco-país mostrou-se superelástico à variação da taxa de juros de longo prazo do Tesouro norte-americano no período da amostra.

    Full Text Available This paper explores whether there is a relationship between humanness and the willingness to share knowledge in Malaysia. Furthermore, the differences between the Malay, Chinese and Indian ethnicities are researched for the presence of humanness and the willingness to share knowledge. Two hundred and fourteen respondents from privately owned companies participated in this research showing that there is a strong relationship between humanness and knowledge sharing. However, the differences between the three ethnicities are small, which is a surprising finding. It can be concluded that people-oriented managers (one of the ways to express humanness are more willing to share knowledge, and differences between ethnicities have no influence in this matter. From these results, it can be recommended to managers and organizations in Malaysia that they pay more attention and be aware of their management style.Stressing the humanness aspects more as they are described could improve the knowledge transfer within companies.

    Full Text Available Bureaucratic corruption is an organizational phenomenon, which faces the trend of countries’ development with serious problems. In spite of all planning and respects of countries to fight against this phenomenon, we are still observing its growth in various aspects of the community. The basic approach emphasized by present study is that it is necessary to establish a corruption prevention system whose central element is social culture and organizational culture rather than relying upon the trends based on punishment after corruption. To perceive the relationship between organizational culture and bureaucratic health of organizations, we used a field approach and selected four governmental organizations namely “governorship”, “municipality”, “traffic police” and “customs to gather the data. We used two questionnaires A and B to gather the data on organizational culture and the relationship between culture and corruption, respectively. Initially, by distributing questionnaire A, we evaluated all four organizations in a manner that two organizations have bureaucratic culture and two organizations with organic culture. Then, questionnaire B was distributed among employees and clients of studied organizations (to acquire realer information on bureaucratic health rate to study the relationship between the type of organizational culture and bureaucratic health. Research statistical population consists of all employees and clients of bureaucratic organizations in Chabahar province located in south east of Iran. Statistical sample consists of 146 clients and 146 employees of all four studied organizations. The results from data analysis show that there is no significant relationship between organic or mechanic organizational culture and employees’ bureaucratic health.

    Full Text Available The purpose of this conducted study was to test the direct and indirect effects of internet banking quality and customer value to customer satisfaction. This study uses descriptive analysis and multiple regression analysis to examine these relationships. The study is based on a survey conducted with respondents who use internet banking in their day-to-day activities, and all questionnaire items are deemed valid and reliable. For data analysis, the descriptive analysis for the indicators, dimensions, and variables proved to be in a good category. Research findings and implications of the regression analysis show that internet banking quality and customer value had a greater direct impact on customer satisfaction, rather the partial relationships of these variables to satisfaction. In the partial relationships, customer value has a higher influence on customer satisfaction, than internet banking quality. As a research recommendation, banks should provide a more humanistic internet banking service for better consumer satisfaction. A major research limitation of the study is that it does not measure service quality of internet banking, and only focuses on customers of internet banking use of one single bank. The originality of this research relies on the insights of internet banking quality leading to customer satisfaction and increasing the value of a bank to its main target markets.

    Full Text Available A new approach to examine the relationship between the excess of forecast based on characteristics toward management forecast and business risk is provided in this research at companies listed on the stock exchange in Tehran.The customary (traditional (approach is based on the regression of management forecast errors of past years. Therefore, the observable and unobservable inputs, such as managements, incentive misalignment, are used to predict management forecast errors. In this study, the future earnings is at first estimated by using characteristics including earnings per share, loss indicator, Neg. accruals per share , Pos. accruals per share ,asset growth , dividend indicator (non-payment of the dividend, Book-to-market value, share price and dividend per share for companies. Based on that, a criterion (CO for estimating the earnings forecast error was developed, which is the alternative forecasted errors. One should notice that, business risk is considered as a measure of company performance. In this study, measures of business risk are volatility of earnings and dividend ratio. Research findings show that, there is a significant relationship between the CO and volatility of earnings, on the contrary there is no significant relationship between this criteria and dividend ratio

    2013-07-01

    The authors propose the Model of Self-Determined Sexual Motivation to examine sexual motivation in dating relationships using a Self-Determination Theory (SDT) framework. This model predicted that sexual need satisfaction would mediate the association between self-determined sexual motives and the outcome variables of psychological well-being and relational quality. Three studies tested this model. Study 1 was a cross-sectional study that investigated sexual motivation in dating relationships. Study 2 was an event-contingent interaction record study that investigated specific sexual interactions over 2 weeks. Study 3 combined event- and interval-contingent methods using a daily diary to examine the model for both partners to enable examination of actor and partner effects. Discussion section focuses on the power of examining SDT in the sexual domain.

  6. EMPIRICAL APPROACH UPON THE RELATIONSHIP BETWEEN CENTRAL BANK INDEPENDENCE AND INFLATION IN DEVELOPED AND DEVELOPING COUNTRIES

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available Central bank independence has become over time one of the key concepts in modern theory and policy. Most economists agree that central bank independence is desirable because it helps achieving and maintaining the long – term goal of price stability. Although one might think about alternative mechanisms to reach lower inflation rates, central bank independence is clearly the most often recomended. The empirical trends upon a more independent central bank with a more transparent and accountable monetary policy regime has emerged in economic literature regarding central banking and monetary economics. In recent years, starting from the Maastricht Treaty central bank independence has become the panacea of the monetary economics and monetary policy approaches. Moreover it is important to analyze and assess the impact of this key issue in central banking upon the inflation performances of the central banks. In this article we provide a qualitative overview upon some recent trends in the central bank independence field: does it still matter? How can be it evaluate and stress it’s impact upon macroeconomic performances, especially upon inflation. As we can observe in the economic literature upon central bank independence there are several approaches to use several indices in order to measure this qualitative and quatitative institutional variables. The most important debate is to eliminate the gap between de jure and de facto independence in order to flatten the measuring of institutional aspects, the legal implication, the constitutional facts and the actual practices of the central banks. Finally, we suggest that according to the new index for measuring central bank independence and inflation targeting index we can evaluate more accurate the degree of the de jure and de facto independence and stress the impact on inflation performance with a case study for ten developed countries and ten developing countries.

    This paper investigates the interactive relationships between oil price shocks and Chinese stock market using multivariate vector auto-regression. Oil price shocks do not show statistically significant impact on the real stock returns of most Chinese stock market indices, except for manufacturing index and some oil companies. Some 'important' oil price shocks depress oil company stock prices. Increase in oil volatility may increase the speculations in mining index and petrochemicals index, which raise their stock returns. Both the world oil price shocks and China oil price shocks can explain much more than interest rates for manufacturing index

    Markets for natural gas in industrialized countries have witnessed profound changes in the past two decades. Trade of natural gas at spot markets in North America and Europe expanded and intensified significantly as a direct result of liberalization efforts. We test the relationships of weekly prices for crude oil and natural gas on either side of the Atlantic Basin between 1999 and 2005. Applying co-integration methodology we identify a move toward integration of historically and geographically separated markets for the homogeneous commodity natural gas. (authors)

  10. Is there a relationship between public expenditures in energy R and D and carbon emissions per GDP? An empirical investigation

    International Nuclear Information System (INIS)

    Garrone, Paola; Grilli, Luca

    2010-01-01

    Energy innovation plays a crucial role in the reduction of carbon emissions. In order to design climate and energy policies that promote the development, deployment and diffusion of new energy technologies, policy makers not only require a theoretical understanding of the energy innovation system, but also empirical evidence of the effects that policy actions have had. This paper focuses on public energy R and D, a traditional and controversial option among the various climate technology policies, and empirically analyses its relationship with carbon emissions per GDP (i.e. carbon intensity) and its two components: energy intensity and the carbon factor. Evidence of the causality links that have prevailed in 13 advanced economies over the 1980-2004 period has been obtained through dynamic panel models. Our findings confirm that government R and D spending is not sufficient by itself to boost the energy innovation process. Public energy R and D has been successful in improving energy efficiency at country level, but it has failed to have a significant impact on the carbon factor and carbon intensity. At the same time the formation of energy R and D budgets is found to be significantly affected by carbon trends. (author)

    Full Text Available Universities and institutions of higher education with a professional, special, educational and cultural environment play important roles in the direction towards the effective management of knowledge and space provision for the sharing of knowledge. Faculty members are known as the main elements of the university and they are the mental and intellectual investment banks who share their knowledge under certain conditions. In addition, their knowledge sharing behaviors lead to the success and improvement of individual and organizational operations. Moreover, organizational intelligence is the capacity of the organization to create knowledge and to use it in a strategic way to coordinate and to conform itself to its surroundings. This study examines the impact of organizational intelligence on faculty members' knowledge sharing behaviors. Data collection for qualitative research includes interviews with experts and quantitative research is performed using a questionnaire. The research results show that there was a significant relationship between organizational intelligence and faculty members' knowledge sharing behaviors. Among these dimensions, “knowledge application” influenced other dimensions. On the other hand, “common outcome” had a significant relationship with the “behavioral” dimension and “special and professional activities”.

    Full Text Available In recent years, there has been good progress on information and communication technology influencing businesses with a new emerging concept called customer relationship management (CRM and it has made significant changes in electronic banking. The primary objective of this paper is to survey electronic banking effects on key CRM components in one of Iranian banks in city of Tehran, Iran. The survey designs a questionnaire and distributes it among some experts in one of selected regions and the results are verified based on t-student and Freedman tests. Results show that all electronic banking services influence on CRM. In addition, that there are no significant differences among effects of electronic services on CRM but each CRM component has different effects on electronic services. In fact, according to freedman test, improving customer relationship process is the most important factor followed by providing appropriate service for each customer, providing appropriate service on appropriate time for each customer and providing appropriate service by appropriate channel for each customer.

    2015-01-01

    In light of the ongoing development and implementation of core competencies in bioethics, it is important to proceed with a clear sense of how bioethics knowledge is utilized in the functioning of hospital ethics committees (HECs). Without such an understanding, we risk building a costly edifice on a foundation that is ambiguous at best. This article examines the empirical relationship between traditional paradigms of bioethics theory and actual decision making by HEC members using survey data from HEC members. The assumption underlying the standardization of qualifications and corresponding call for increased education of HEC members is that they will base imminent case decisions on inculcated knowledge. Our data suggest, however, that HEC members first decide intuitively and then look for justification, thereby highlighting the need to re-examine the pedagogical processes of ethics education in the process of standardizing and improving competencies.

    Full Text Available The purpose of this paper is to assess the quality of disclosures related to financial instruments provided in annual financial statements of Macedonian listed companies and empirically investigate factors that have the potential to influence the quality of these disclosures in accordance with IFRS 7 requirements. Based on the postulates and the results of the empirical investigations of prior IAS compliance studies I have constructed a disclosure index for each listed company and performed regression analysis with independent variables representing some characteristics of listed companies investigated, such as their size, industry, type of auditor engaged, ownership concentration, profitability and leverage. My regression analysis results supported the conclusion that the level of compliance with IFRS 7 requirements is related to the type of auditor engaged and ownership concentration in investigated companies. The results of my research will contribute the large body of empirical studies on IFRS disclosure and compliance, providing evidence from South- East European Transitional Economy that adopted IFRS as national financial reporting framework.

  17. The relationship between oil price shocks and China's macro-economy. An empirical analysis

    International Nuclear Information System (INIS)

    Du, Limin; Yanan, He; Wei; Chu

    2010-01-01

    This paper investigates the relationship between the world oil price and China's macro-economy based on a monthly time series from 1995:1 to 2008:12, using the method of multivariate vector autoregression (VAR). The results show that the world oil price affects the economic growth and inflation of China significantly, and the impact is non-linear. On the other hand, China's economic activity fails to affect the world oil price, which means that the world oil price is still exogenous with respect to China's macro-economy in time series sense, and China has not yet had an oil pricing power in the world oil markets. The structural stability tests demonstrate that there is a structural break in the VAR model because of the reforms of China's oil pricing mechanism, thus it is more appropriate to break the whole sample into different sub-samples for the estimation of the model.

    2014-01-01

    Organizational researchers argue that workplace mistreatment scholarship is hampered because of the wide variety of constructs studied. To investigate this concern, we conducted an item-level analysis of the relationship among workplace mistreatment experiences to assess construct overlap. Employed students reported how similar 17 mistreatment experiences were to one another (i.e., from measures of sexual harassment, generalized harassment, and incivility) and subject matter experts indicated the degree to which each experience represented several dimensions including Buss's (1961) dimensions (i.e., verbal/physical, active/passive, and direct/indirect) and others (i.e., sexual/ nonsexual and intentional/accidental). Nonsexual forms of mistreatment (i.e., generalized harassment and incivility) were perceived similarly despite their different conceptual definitions, whereas sexual harassment experiences were relatively distinct. Implications of the findings are discussed.

    2012-07-28

    Multiparameter linear energy-density relationships to model solvent effects in room temperature ionic liquids (RTILs) are introduced and tested. The model incorporates two solvent dependent and two specific solute-solvent parameters represented by a set of electronic indexes derived from the conceptual density functional theory. The specific solute-solvent interactions are described in terms of the electronic chemical potential for proton migration between the anion or cation and the transition state structure of a specific reaction. These indexes provide a quantitative estimation of the hydrogen bond (HB) acceptor basicity and the hydrogen bond donor acidity of the ionic solvent, respectively. A sound quantitative scale of HB strength is thereby obtained. The solvent dependent contributions are described by the global electrophilicity of the cation and nucleophilicity of the anion forming the ionic liquid. The model is illustrated for the kinetics of cycloaddition of cyclopentadiene towards acrolein. In general, cation HB acidity outweighs the remaining parameters for this reaction.

    Full Text Available Current academic research on the relationship of firms’ CSR activities with corporate branding typically focuses on consumers’ and shareholders’ viewpoints. This research aims to shed light on how organisational members in firms perceive to be the impact of CSR activities upon their corporate brand strategy. Using a survey administered to companies in the U.K. and Bulgaria, the author investigate, firstly, organisational members’ perceptions of the impact of different CSR-related activities upon corporate branding and, secondly, their beliefs about what customers and shareholders think are the impacts of CSR-related activities upon brand image and brand identity. The findings indicated that while organisational members rated quality products, customer service and corporate governance highly as key components of CSR activity, they were much more ambivalent about their companies'commitment to broader actions which involve the 'community' and 'society'. This paper concludes by discussing the implications of the findings for future 'CSR education' among companies.

    Full Text Available Previous research has suggested a positive effect of physical activity on life satisfaction. Little research exists that has investigated the relationship between physical fitness and life satisfaction. For this purpose, this research was done to determine the relationship between physical fitness and life satisfaction in a sample of university men and women. Participants (N = 28, Mage = 22.18 completed multiple indicators of physical fitness including cardiovascular fitness, muscular fitness, body composition and flexibility, and life satisfaction (SWLS. Descriptive and one-way between-groups ANOVAs were performed to determine gender differences on measures of life satisfaction and measures of fitness. In addition, the relationship between the five health-related components of fitness and life satisfaction were investigated using Pearson’s product–moment correlation coefficient. Analyses indicated there were no significant correlations between any of the health-related components of fitness and scores on the SWLS. There were significant gender differences on all physical fitness measures, except partial curl-ups, but no significant gender differences on life satisfaction. Our findings suggest that improved physical fitness does not have a relationship with higher life satisfaction measures. Further tests, utilizing larger sample sizes, are recommended.

    Full Text Available Performance appraisal politics are viewed as a vital human resource management issuewhere it consists of two salient features: motivational motive and punishment motive. The ability ofappraisers (e.g., immediate bosses/managers to properly implement such appraisal politics inallocating performance ratings may have significant impact on job satisfaction. Although the nature ofthis relationship is important, little is known about the role of performance appraisal politics as apredicting variable in the performance appraisal models. Therefore, this study was conducted toexamine the effect of performance appraisal politics on job satisfaction using 150 usablequestionnaires gathered from employees who have worked in a national postal company in Sarawak,Malaysia. In initial data analysis, the results of exploratory factor analysis confirmed that themeasurement scales used in this study satisfactorily met the standards of validity and reliabilityanalyses. Further, in hypothesis testing, the outcomes of stepwise regression analysis showed thatperformance appraisal politics (i.e., motivational motive and punishment motive significantlycorrelated with job satisfaction. Statistically, this result confirms that performance appraisal politicsact as important predictors of job satisfaction in the studied organization. In addition, discussion,implications and conclusion are elaborated.

    2009-07-01

    Full Text Available Compensation management literature highlights that income has three major features: salary, bonus and allowance. If the level and/or amount of income are distributed to employees based on proper rules this may increase pay satisfaction. More importantly, a thorough investigation in this area reveals that the effect of income distribution on pay satisfaction is not consistent if perceived value of money is present in organizations. The nature of this relationship is less emphasized in pay distribution literature. Therefore, this study was conducted to measure the effect of the perceived value of money and income distribution on pay satisfaction using 136 usable questionnaires gathered from employees who have worked in one city based local authority in Sabah, Malaysia (MSLAUTHORITY. Outcomes of hierarchical regression analysis showed that the interaction between perceived value of money and income distribution significantly correlated with pay satisfaction.

    Full Text Available Within the last few decades, the extended use of biodiesel and bioethanol has established interlinkages between energy markets and agricultural commodity markets. The present work examines the bivariate relationships of crude oil–corn and crude oil–soybean futures prices with the assistance of the ARDL cointegration approach. Our findings confirm that crude oil prices affect the prices of agricultural products used in the production of biodiesel, as well as of ethanol, validating the interaction of energy and agricultural commodity markets. The practical value of the present work is that the findings provide policy makers with insight into the interlinkages between agricultural and energy markets to promote biodiesel or bioethanol by affecting crude oil prices. The novelty of the present work stands on the use of futures prices that incorporate all available information and thus are more appropriate to identify supply and demand shocks and price spillovers than real prices. Finally, the period of study includes extremely low, as well as extremely high, crude oil prices and the results illustrate that biofuels cannot be substituted for crude oil and protect economies from energy volatility.

    Full Text Available Purpose – Based on the tenets of the stakeholder theory, the study investigates the influence of corporate governance best practices on 'hard' and 'soft' human resource management practices in public listed companies in Malaysia. Design/methodology/approach – Data was collected from public listed companies in the consumer product sector via structured questionnaire. Multiple regression analysis is conducted using SPSS to test the hypotheses. Findings – The findings suggest that board of directors' independence significantly predicts training and development practices. It is also evidenced that audit committee's effectiveness is significantly related to team-based work. Research limitations/implications - The study is conducted in a single sector of the economy resulted to a small number of listed companies. Originality/value – The significant relationship between board of directors' independence and training and development; and audit committee effectiveness and team-based work indicate that training and development and team-based work are ingrained in the companies' HRM practices, more acceptable and the least complicated to implement. Indicating that public listed companies are answerable to various stakeholders, thus, making it difficult to introduce and implement certain HRM practices.

    Full Text Available In the heart of the debate on the appropriate level of the profit tax burden on host countries lies a challenging question: How does FDI respond to tax rates? Studies analyzing inter-state fluctuation show that, on average, FDI decreases by 3.7% when corporate tax rates increase by one percentage point, other studies show that the FDI decline varies between 0 and 5%. Such variations reflect differences between nations and industries studied, as well as differences between time periods which have been considered. More recent studies show that FDI becomes increasingly sensitive to tax reflecting a growing mobility of capital as non-tax barriers, previously in the way of FDI, are eliminated (OCDE, 2008.The present article aims to study the effects of tax upon foreign direct investment in Romania. The period studied prolongs on ten years, from 1999 to 2009, with the aim to observe the effects of modifications upon tax revenues, direct tax and indirect tax on foreign investment in Romania. To study the relationship between the variables, econometric modelling has been used thanks to the software package Eviews 5.0. This paper’s main conclusion is that foreign direct investment are not discouraged by the level of tax in Romania, on the contrary, they are stimulated by an eventual increase in tax revenue.

    Health care organizations are pressured to improve the cost-effectiveness of service delivery. Clinical governance is an important trigger to improve care quality and safety and rank high in the reform agenda of health systems. The senior management team culture plays a major role in establishing clinical governance practices, because it strongly influences the values, attitudes, and behaviors of the members of an organization. The aim of this study was to investigate the relationship between senior management team culture and clinical governance in the public health care organizations of three Italian regions. The assessment of senior management culture was conducted using the Competing Values Framework and a corresponding instrument adapted for the Italian context. Clinical governance was assessed using an ad hoc instrument focused on the senior management team's perception and attitude toward clinical governance. The survey achieved a 54% response rate. The results of four different models demonstrate that organizations characterized by different dominant cultures are associated with significant differences in attitudes toward clinical governance. In particular, on average, dominant cultures with a prevailing external focus are associated with a more positive attitude toward clinical governance. The selection and appointments of top managers should consider the style of leadership that is most apt to facilitate the growth of rational and developmental cultures. Furthermore, the training of top managers and leading doctors should reinforce leadership aptitude and approaches that are consistent with the desired organizational cultures.

    The job satisfaction of academics is related to a number of variables of complex function such as demographic characters, the work itself, pay, work responsibilities, variety of tasks, promotional opportunities, relationship with co-workers and others. Academics may be simultaneously satisfied with some facets of the job and dissatisfied with others. This paper aims at determining the influential factors that contribute to the enhancement or reduction of academics' job satisfaction among private universities in Bangladesh with special reference to Dhaka, the capital city of Bangladesh. A total of 346 respondents are considered from ten private universities using non-probability sampling. A pre-tested and closed-ended questionnaire using a seven-point Likert scale is used for data collection. In this study, descriptive statistics, Pearson product moment correlation, multiple regression, and factor analysis are exercised as statistical tools. A conceptual model of job satisfaction is developed and applied for academics' job satisfaction. The results reveal that compensation package, supervisory support, job security, training and development opportunities, team cohesion, career growth, working conditions, and organizational culture and policies are positively associated with the academics' job satisfaction. Amongst them, three factors stood out as significant contributors for job satisfaction of academics i.e. compensation package, job security, and working conditions. Therefore, the management of private universities should focus their effort on these areas of human resource management for maintaining academics' job satisfaction and employee retention. The study will be useful for university management in improving overall job satisfaction as it suggests some strategies for employee satisfaction practices.

    2015-07-01

    Full Text Available Our study focuses on commercial banks which are operating in Bulgaria and Romania, two countries whose banking sectors have registered major structural changes in the transition to a market economy and which are showing some similarities. Similar to other EU countries, the financial system from Bulgaria and Romania is dominated by the banking sector, which holds the largest share of total assets. Thus, we can say that health, strength and performance of the banking sector are of major importance for the sustainable economic development of states, but also for efficient transmission of monetary policy decisions on the real economy. The paper aims to identify the key factors that affect bank profitability and to evaluate empirically their contribution to a sample of 29 commercial banks in Bulgaria and Romania, for the period 2003-2012. Our research is based on data from the Bureau Van Dijk database, the World Bank and the European Central Bank and uses panel data estimation techniques. The dependent variable used in our study is the bank profitability, which is measured by two representative indicators the Return on Average Assets (ROAA and Return on Average Equity (ROAE. Regarding the independent variables, our analysis includes capital adequacy, the loan loss reserve rate, cost to income ratio, the ratio of liquid assets to total assets, the interest expenses to deposits ratio, the non-interest income over total gross revenues, bank size, the GDP per capita growth, inflation rate, domestic bank credit to private sector and banking industry concentration. The results of our empirical study shows that among the variables considered, the loan loss reserve rate, the ratio of cost to income, GDP per capita growth and domestic bank credit to the private sector, have a significant impact on bank profitability, results in line with our expectations, but also with the results of other empirical studies.

    The purpose of this study was to explore the relationships among employees' usage intention pertaining to mobile information devices, focusing on subjective judgement, technology acceptance tendency, information sharing behavior and information transfer. A research model was established to verify several hypotheses. The research model based on integrated concepts of knowledge management and technology acceptance modeling. Participants were employees of enterprises in Taiwan, selected by combining snowball and convenience sampling. Data obtained from 779 e-surveys. Multiple-regression analysis was employed for hypothesis verification. The results indicate that perceived ease-of-use of mobile devices was affected by computer self-efficacy and computer playfulness directly; meanwhile, perceived ease-of-use directly affects perceived usefulness. In addition, perceived ease-of-use and perceived usefulness can predict information-sharing behavior in a positive manner, and impact knowledge transfer as well. Based on the research findings, it suggested that enterprises should utilize mobile information devices to create more contact with customers and enrich their service network. In addition, it is recommended that managers use mobile devices to transmit key information to their staff and that they use these devices for problem-solving and decision-making. Further, the staff’s skills pertaining to the operation of mobile information devices and to fully implement their features are reinforced in order to inspire the users' knowledge transfer. Enhancing the playfulness of the interface is also important. In general, it is useful to promote knowledge transfer behavior within an organization by motivating members to share information and ideas via mobile information devices. In addition, a well-designed interface can facilitate employees' use of these devices. PMID:28886088

    Large old trees are critically important keystone structures in forest ecosystems globally. Populations of these trees are also in rapid decline in many forest ecosystems, making it important to quantify the factors that influence their dynamics at different spatial scales. Large old trees often occur in forest landscapes also subject to fire and logging. However, the effects on the risk of collapse of large old trees of the amount of logging and fire in the surrounding landscape are not well understood. Using an 18-year study in the Mountain Ash (Eucalyptus regnans) forests of the Central Highlands of Victoria, we quantify relationships between the probability of collapse of large old hollow-bearing trees at a site and the amount of logging and the amount of fire in the surrounding landscape. We found the probability of collapse increased with an increasing amount of logged forest in the surrounding landscape. It also increased with a greater amount of burned area in the surrounding landscape, particularly for trees in highly advanced stages of decay. The most likely explanation for elevated tree fall with an increasing amount of logged or burned areas in the surrounding landscape is change in wind movement patterns associated with cutblocks or burned areas. Previous studies show that large old hollow-bearing trees are already at high risk of collapse in our study area. New analyses presented here indicate that additional logging operations in the surrounding landscape will further elevate that risk. Current logging prescriptions require the protection of large old hollow-bearing trees on cutblocks. We suggest that efforts to reduce the probability of collapse of large old hollow-bearing trees on unlogged sites will demand careful landscape planning to limit the amount of timber harvesting in the surrounding landscape.

  17. Ergonomics, quality and continuous improvement--conceptual and empirical relationships in an industrial context.

    1997-10-01

    This paper reviews the literature comparing the fields of ergonomics and quality, mainly in an industrial context, including mutual influences, similarities and differences. Relationships between ergonomics and the factors: work conditions, product design, ISO 9000, continuous improvements and TQM are reviewed in relation to the consequence, application, and process domains. The definitions of ergonomics and quality overlap substantially. Quality deficiencies, human errors and ergonomics problems often have the same cause, which in many cases can be traced to the design of work, workplace and environment e.g. noise, light, postures, loads, pace and work content. In addition, the possibility of performing to a high standard at work is an important prerequisite for satisfaction and well-being. Contradictions between the two fields have been identified in the view of concepts such as standardization, reduction of variability and copying of best practice, requiring further research. The field of quality would gain by incorporating ergonomics knowledge, especially in the areas of work design and human capability, since these factors are decisive for human performance and also therefore the performance of the systems involved. The field of ergonomics, on the other hand, would benefit from developing a stronger emphasis on methodologies and structures for improvement processes, including a clearer link with leadership and company strategies. Just as important is a further development of practicable participative ergonomics methods and tools for use at workplaces by the workers themselves, in order to integrate the top-down and the bottom-up processes and achieve better impact. Using participative processes for problem-solving and continuous improvement, focusing ergonomics and quality jointly has a great potential for improving working conditions and quality results simultaneously, and satisfying most of the interested parties.

    We present the results of an application of Bayesian inference in testing the relation between risk and return on the financial instruments. On the basis of the Intertemporal Capital Asset Pricing Model, proposed by Merton we built a general sampling distribution suitable in analysing this relationship. The most important feature of our assumptions is that the skewness of the conditional distribution of returns is used as an alternative source of relation between risk and return. This general specification relates to Skewed Generalized Autoregressive Conditionally Heteroscedastic-in-Mean model. In order to make conditional distribution of financial returns skewed we considered the unified approach based on the inverse probability integral transformation. In particular, we applied hidden truncation mechanism, inverse scale factors, order statistics concept, Beta and Bernstein distribution transformations and also a constructive method. Based on the daily excess returns on the Warsaw Stock Exchange Index we checked the empirical importance of the conditional skewness assumption on the relation between risk and return on the Warsaw Stock Market. We present posterior probabilities of all competing specifications as well as the posterior analysis of the positive sign of the tested relationship.

    Full Text Available Inter-organizational communication plays an important role in promoting strategic collaboration among firms. It can improve productivity and increases collaboration among employees. In this paper, we present an empirical study to measure the role of inter-organizational communication on efficiency among administration employees who work for one the oldest banks in Iran, Bank Melli Iran. The study uses 380 full time employees who work for 28 different administration divisions of this bank. The survey uses a questionnaire consists of 19 questions about inter-organizational communication and 25 questions about efficiency of employees. The reliability of the survey has been approved using an initial survey and Cronbach alpha was calculated as 0.87, which is well above the minimum acceptable level. The result of our survey confirms there is a meaningful relationship between inter-organizational communication and efficiency of all administration employees who work for this bank. There is also a meaningful relationship between age and efficiency and the maximum efficiency belongs to people aged 31 to 40. According to our survey, men have more inter-organizational efficiency than women do. The result of our survey also confirms that positivism impacts more than other factors on efficiency. Among five effective factors, empathy has the most impact and responsiveness 6 efficiency dimensions.

    2009-01-01

    In 1977, Taylor proposed a constant elasticity model relating capacity choice in mines to reserves. A test of this model using a very large (n = 1,195) dataset confirms its validity but obtains significantly different estimated values for the model coefficients. Capacity is somewhat inelastic with respect to reserves, with an elasticity of 0.65 estimated for open-pit plus block-cave underground mines and 0.56 for all other underground mines. These new estimates should be useful for capacity determinations as scoping studies and as a starting point for feasibility studies. The results are robust over a wide range of deposit types, deposit sizes, and time, consistent with physical constraints on mine capacity that are largely independent of technology. ?? 2009 International Association for Mathematical Geology.

    Full Text Available This research empirically measures the economic exposure of 11 selected miscellaneous companies in Indonesia. It also attempts to empirically explore the influence of firm size, export, liquidity, and leverage on the economic exposure of those companies. Annual data from 2007 to 2010, which was collected from the www.idx.co.id and www.bi.go.id were used and analyzed by the multiple linear regression to measure the economic exposure and examine the influences of the firm size, export, liquidity, and leverage on the economic exposure. Both partial (t-test and simultaneous (F-test hypotheses were constructed and tested using the software of SPSS for Windows. The research documented that, with the exception of the liquidity, which has a negative and significant effect partially on the economic exposure, all other variables, i.e., the firm size, export, and leverage were found to have insignificant effects. Meanwhile, based on the F-test, the research found that the firm size, export, liquidity, and leverage affected simultaneously and significantly the economic exposure of the companies. These findings imply that in order to manage their economic exposure, the companies should control these variables, especially the liquidity.

    Densities of a large number of mixed uranyl nitrate-thorium nitrate solutions were measured with pycnometer. By the least squares analysis of the experimental result, an empirical formula for determining water content of mixed uranyl nitrate-thorium nitrate solutions as functions of uranium concentration, thorium concentration and nitric acid normality is derived; W=1.0-0.3580 C u -0.4538 C Th -0.0307H + where W, C u , C Th , and H + stand for water content(g/cc), uranium concentration (g/cc), thorium concentration(g/cc), and nitric acid normality, respectively. Water contents of the mixed uranyl nitrate-thorium nitrate solutions are calculated by using the empirical formular, and compared with the values calculated by Bouly's equation in which an additional data, solution density, is required. The two results show good agreements within 2.7%. (Author)

  5. On the Relationship between Fourier and Response Spectra: Implications for the Adjustment of Empirical Ground-Motion Prediction Equations (GMPEs)

    Often, scaling of response spectral amplitudes, (e.g., spectral acceleration) obtained from empirical ground motion prediction equations (GMPEs), with respect to commonly used seismological parameters such as magnitude, distance and site condition is assumed/referred to be representing a similar scaling of Fourier spectral amplitudes. For instance, the distance scaling of response spectral amplitudes is related with the geometrical spreading of seismic waves. Such comparison of scaling of response spectral amplitudes with that of corresponding Fourier spectral amplitudes is motivated by that, the functional forms of response spectral GMPEs are often derived using the concepts borrowed from Fourier spectral modeling of ground motion. As these GMPEs are subsequently calibrated with empirical observations, this may not appear to pose any major problems in the prediction of ground motion for a particular earthquake scenario. However, the assumption that the Fourier spectral concepts persist for response spectra can lead to undesirable consequences when it comes to the adjustment of response spectral GMPEs to represent conditions not covered in the original empirical data set. In this context, a couple of important questions arise, e.g., what are the distinctions and/or similarities between Fourier and response spectra of ground-motions? And, if they are different, then what is the mechanism responsible for such differences and how do adjustments that are made to FAS manifest in response spectra? We explore the relationship between the Fourier and response spectrum of ground motion by using random vibration theory (RVT). With a simple Brune (1970, 1971) source model, RVT-generated acceleration spectra for a fixed magnitude and distance scenario are used. The RVT analyses reveal that the scaling of low oscillator-frequency response spectral ordinates can be treated as being equivalent to the scaling of the corresponding Fourier spectral ordinates. However, the high

    From an economic perspective that understood it as a spillover of development, migration is now also the subject of socioeconomic investigation incorporating the problems of assimilation, relative deprivation and isolation. The corollary is an increased emphasis on economic and social understanding of migration and its consequences. This entails studying migration or migrants in terms of factors beyond income. Health outcome is important among these non-income factors but at the same time remains less studied. Although there have been a few influential studies on health issues as linked to migration status, the issue of malnutrition in this context continues to be under-researched. This paper explores, theoretically and empirically, migration status and malnutrition in Mumbai in India. An econometric analysis of Demographic and Health Survey data gives insight into the dynamics of child and maternal undernutrition as mediated by migration status in Mumbai.

    Full Text Available Notwithstanding the consensus among most classical and contemporary scholars on the permissibility of cash or money for Waqf purpose, its apparent limited application to religious purposes in Malaysia undermines its potentials for socio-economic development. Extant Malaysia theoretical and conceptual studies only offered remarks on the likely low levels of application of this very important variant of Waqf in Malaysia. Thus a lacuna exists to empirically assess the level of awareness and unravel the likely factors that explain such limited application of Cash Waqf in Malaysia. In an attempt to fill this gap in this study, data elicited from respondents via an adopted survey instrument was subjected to both descriptive and inferential statistical analysis. The results indicated that the awareness level is still low and that social culture, lack of promotion, and lack of understanding statistically and significantly explain the level of awareness and application about Cash Waqf among the respondents. Recommendations contingent on research findings were offered.

    There is a high degree of misallocated medical care for patients with somatoform disorders and patients with concomitant mental diseases. This complex of problems could be reduced remarkably by integrating psychosomatic departments into hospitals with maximum medical care. Admitting a few big psychosomatic specialist clinics into the calculation basis decreased the Day-Mix Index (DMI). The massive reduction of the calculated costs per day leads to a gap in funding resulting in a loss of the necessary personnel requirements - at least in university psychosomatic departments. The objective of this article is therefore to empirically verify the reference numbers of personnel resources calculated on the basis of the new German lump-sum reimbursement system in psychiatry and psychosomatics (PEPP). The minute values of the reference numbers of Heuft (1999) are contrasted with the minute values of the PEPP reimbursement system in the years 2013 and 2014, as calculated by the Institute for Payment Systems in Hospitals (InEK). The minute values derived from the PEPP data show a remarkable convergence with the minute values of Heuft's reference numbers (1999). A pure pricing system like the PEPP reimbursement system as designed so far threatens empirically verifiable and qualified personnel requirements of psychosomatic departments. In order to ensure the necessary therapy dosage and display it in minute values according to the valid OPS procedure codes, the minimum limit of the reference numbers is mandatory to maintain the substance of psychosomatic care. Based on the present calculation, a base rate of at least 285 e has to be politically demanded. Future developments in personnel costs have to be refinanced at 100 %.

    Full Text Available Este artigo fornece evidências empíricas sobre a relação entre Valor Econômico Adicionado (EVA e retornos acionários de empresas brasileiras. A relação entre essas variáveis têm sido motivo de controvérsia nos últimos anos, com alguns autores encontrando associações significativas entre elas, enquanto outros não encontrando nenhuma. A hipótese de que o EVA afeta os retornos acionários é testada através de regressão linear, utilizando-se modelos alternativos. A amostra é composta de empresas negociadas na mais importante bolsa de valores brasileira. Uma comparação entre os resultados deste estudo com os de estudos anteriores mostram que resultados significativos dependem da determinação das variáveis apropriadas (retornos acionários versus preços das ações, bem como da correta relação dinâmica entre a variável dependente e a independente. This paper provides empirical evidence on the relationship between Economic Value Added (EVA and stock returns in Brazilian firms. This relationship between these variables has been subject to controversy in recent years, with some authors finding significant associations between them while others find none. The hypothesis that EVA affects stock returns is tested through linear regression, using alternative models. The sample is comprised of companies that are traded on the most important Brazilian stock exchange. A comparison of the outcomes of our study with those of previous studies shows that significant results depend on determination of the appropriate variables (stock returns versus stock prices, as well as of the correct dynamic structure between the dependent and the explanatory variable.

    The relationship between intelligence and creativity has been subject to empirical research for decades. Nevertheless, there is yet no consensus on how these constructs are related. One of the most prominent notions concerning the interplay between intelligence and creativity is the threshold hypothesis, which assumes that above-average intelligence represents a necessary condition for high-level creativity. While earlier research mostly supported the threshold hypothesis, it has come under fire in recent investigations. The threshold hypothesis is commonly investigated by splitting a sample at a given threshold (e.g., at 120 IQ points) and estimating separate correlations for lower and upper IQ ranges. However, there is no compelling reason why the threshold should be fixed at an IQ of 120, and to date, no attempts have been made to detect the threshold empirically. Therefore, this study examined the relationship between intelligence and different indicators of creative potential and of creative achievement by means of segmented regression analysis in a sample of 297 participants. Segmented regression allows for the detection of a threshold in continuous data by means of iterative computational algorithms. We found thresholds only for measures of creative potential but not for creative achievement. For the former the thresholds varied as a function of criteria: When investigating a liberal criterion of ideational originality (i.e., two original ideas), a threshold was detected at around 100 IQ points. In contrast, a threshold of 120 IQ points emerged when the criterion was more demanding (i.e., many original ideas). Moreover, an IQ of around 85 IQ points was found to form the threshold for a purely quantitative measure of creative potential (i.e., ideational fluency). These results confirm the threshold hypothesis for qualitative indicators of creative potential and may explain some of the observed discrepancies in previous research. In addition, we obtained

    Major contributions from pathogen genome analysis and host genetics have equated the possibility of Mycobacterium tuberculosis co-evolution with its human host leading to more stable sympatric host–pathogen relationships. However, the attribution to either sympatric or allopatric categories depends on the resolution or grain of genotypic characterization. We explored the influence on the sympatric host-pathogen relationship of clinical (HIV infection and multidrug-resistant tuberculosis [MDRTB]) and demographic (gender and age) factors in regards to the genotypic grain by using spacer oligonucleotide typing (spoligotyping) for classification of M. tuberculosis strains within the Euro-American lineage. We analyzed a total of 547 tuberculosis (TB) cases, from six year consecutive sampling in a setting with high TB-HIV coinfection (32.0%). Of these, 62.0% were caused by major circulating pathogen genotypes. The sympatric relationship was defined according to spoligotype in comparison to the international spoligotype database SpolDB4. While no significant association with Euro-American lineage was observed with any of the factors analyzed, increasing the resolution with spoligotyping evidenced a significant association of MDRTB with sympatric strains, regardless of the HIV status. Furthermore, distribution curves of the prevalence of sympatric and allopatric TB in relation to patients’ age showed an accentuation of the relevance of the age of onset in the allopatric relationship, as reflected in the trimodal distribution. On the contrary, sympatric TB was characterized by the tendency towards a typical (standard) distribution curve. Our results suggest that within the Euro-American lineage a greater degree of genotyping fine-tuning is necessary in modeling the biological processes behind the host-pathogen interplay. Furthermore, prevalence distribution of sympatric TB to age was suggestive of host genetic determinisms driven by more common variants. PMID:26529092

    The Milky Way dark matter halo is formed from the accretion of smaller subhalos. These sub-units also harbor stars-typically old and metal-poor-that are deposited in the Galactic inner regions by disruption events. In this Letter, we show that the dark matter and metal-poor stars in the Solar neighborhood share similar kinematics due to their common origin. Using the high-resolution eris simulation, which traces the evolution of both the dark matter and baryons in a realistic Milky Way analog galaxy, we demonstrate that metal-poor stars are indeed effective tracers for the local, virialized dark matter velocity distribution. The local dark matter velocities can therefore be inferred from observations of the stellar halo made by the Sloan Digital Sky Survey within 4 kpc of the Sun. This empirical distribution differs from the standard halo model in important ways and suggests that the bounds on the spin-independent scattering cross section may be weakened for dark matter masses below ∼10  GeV. Data from Gaia will allow us to further refine the expected distribution for the smooth dark matter component, and to test for the presence of local substructure.

    Full Text Available This study aims to analyze the global mobile phones by examining the instruments stimulating the diffusion pattern. A rigorous demand model is estimated using global mobile telecommu-nications panel dataset comprised with 51 countries classified in order to World Bank income categories from 1990-2007. In particular, the paper examines what factors contribute the most to the deployment of global mobile telephones. To construct an econometric model, the number of subscribers to mobile phone per 100 inhabitants is taken as dependent variable, while the following groups of variables (1 GDP per capita income and charges, (2 competition policies (3 telecom infrastructure (4 technological innovations (5 others are selected as independent variables. Estimation results report the presence of substantial disparity among groups. Additionally GDP per capita income and own-price elasticity comprised with call rate, subscription charges, are reported. The analysis of impulse responses for price, competition policies, and technological innovations such as digitalization of mobile network, mobile network coverage indicates that substantial mobile telephone growth is yet to be realized especially in developing countries. A new and important empirical finding is that there are still many opportunities available for mobile phone development in the world pro-poor nations by providing better telecom infrastructure.

    2015-12-01

    Full Text Available This paper contributes to on-going empirical search for an appropriate crude oil price benchmark that ensures greater financial stability and efficient fiscal management in Nigeria. It adopted the seasonally adjusted ARIMA forecasting models using monthly data series from 2000m01 to 2012m12 to predict future movement in Nigeria crude oil prices. The paper derived a more robust and dynamic framework that accommodates fluctuation in crude oil price and also in government spending. The result shows that if the incessant withdrawal from the ECA fund and the increasing debt profile of government in recent times are factored into the benchmark, the real crude oil numerical fiscal rule is (US$82.3 for 2013 which is higher than the official benchmark of $75 used for 2013 and 2014 budget proposal. The paper argues that the current long run price rule based on 5-10 year moving average approach adopted by government is rigid and inflexible as a rule for managing Nigerian oil funds. The unrealistic assumption of the extant benchmark accounted for excessive depletion and lack of accountability of the excess crude oil account. The paper concludes that except the federal government can curtail its spending profligacy and adopts a more stringent fiscal discipline rules, the current benchmark is unrealistic and unsuitable for fiscal management of oil revenue in the context of Nigerian economic spending profile.

    Full Text Available Today, there is no doubt that in many organizations, many employees refuse to provide their opinions and comments about the organizational problems. In fact, in many organizations there is a created climate, which often makes employees feel their opinion is not valued. This phenomenon is examined as an organizational silence that by identifying the factors affecting on it we can effectively take steps to eliminate barriers to commenting staff in organizations. In this regard, this paper presents an empirical work conducted on data obtained from 260 employees Payame Noor University of East Azerbaijan Province. These data are analyzed by SPSS software and regression and path analysis tests. The results showed that there is a significant relationship between silence climate dimensions and employee organizational commitment with silence behavior employee. In addition, there is a positive correlation between higher management attitudes and supervisor’s attitudes with workers silent behavior. We have also observed that there is a negative correlation between communication opportunities and organizational commitment with employee silence behavior of employees.

    Full Text Available The price to earnings ratio (P/E is widely used, particularly by practitioners, as a measure of relative stock valuation. Price to earnings is an indicator which indicates current mood of investors how much they are willing to pay per unit of company earnings. Traditionally, the P/E ratio has been assumed to be an indicator of the quality of an investment; a relatively low P/E ratio implies a good investment, whereas a relatively high P/E ratio indicates a “poor” investment prospect. The aim of this study is to identify relationship among market stock return, dividend yields and price to earnings ratio affect in the period 2000.01-2009.12. Therefore, to determine long-run and short-run relationship, Johansen cointegration tests, error-correction models and Granger causality tests are used.

    Full Text Available Costumer relationship and the comprehension of their behavior is a crucial factor for efficient market performance. A web survey was conducted to evaluate the impact of perceived quality upon attitudes and behavioral intentions of electrical power consumers. The model was evaluated using structural equation techniques. The survey was performed among 922 commercial and industrial consumers. We verified that Commitment, with Value (and Perceived Quality, Satisfaction and Confidence as its antecedents, should be monitored and incremented. The hypothesis that quality determines the satisfaction of the concessionaire’s customers was confirmed, as Satisfaction exerts significant impact upon behavioral intentions of customers regarding the concessionaire. This research contributes by proposing a marketing relationship model in a BtoB context, a semi-monopoly scenario (which is rare. In addition, it suggests actions and quality variables considered by customers in their company evaluations, indicating important managerial implications.

    More than 20% of the electricity generated in India is lost to rampant thefts. Drawing data from 28 states of India over a time span of five years (2005–2009), this paper examines the role played by socio-economic and governance factors in determining the extent of electricity thefts in Indian states. Results from the Feasible Generalised Least Squares (FGLS) model demonstrate that lesser corruption, higher state tax to GDP ratio, greater collection efficiency of electricity bills by state utilities, higher share of private installed capacity, lesser poverty, greater literacy and greater income are closely associated with lesser power thefts. A better understanding of the key determinants of thefts in electricity distribution is vital for policy makers for designing policies. - Highlights: •Over 20% of total electricity generated in India is lost to thefts. •The study attempts to identify the determinants of electricity theft in India. •Use of panel data from 2005 to 2009 for 28 Indian states. •FGLS and OLS regression results are compared. •The determinants of power theft are both governmental and socio-economic in nature.

    The validation of health economic (HE) model outcomes against empirical data is of key importance. Although statistical testing seems applicable, guidelines for the validation of HE models lack guidance on statistical validation, and actual validation efforts often present subjective judgment of graphs and point estimates. To discuss the applicability of existing validation techniques and to present a new method for quantifying the degrees of validity statistically, which is useful for decision makers. A new Bayesian method is proposed to determine how well HE model outcomes compare with empirical data. Validity is based on a pre-established accuracy interval in which the model outcomes should fall. The method uses the outcomes of a probabilistic sensitivity analysis and results in a posterior distribution around the probability that HE model outcomes can be regarded as valid. We use a published diabetes model (Modelling Integrated Care for Diabetes based on Observational data) to validate the outcome "number of patients who are on dialysis or with end-stage renal disease." Results indicate that a high probability of a valid outcome is associated with relatively wide accuracy intervals. In particular, 25% deviation from the observed outcome implied approximately 60% expected validity. Current practice in HE model validation can be improved by using an alternative method based on assessing whether the model outcomes fit to empirical data at a predefined level of accuracy. This method has the advantage of assessing both model bias and parameter uncertainty and resulting in a quantitative measure of the degree of validity that penalizes models predicting the mean of an outcome correctly but with overly wide credible intervals.

    Climate indices characterize climate systems and may identify important indicators for long-term precipitation, which are driven by climate interactions in atmosphere-ocean circulation. In this study, we investigated the climate indices that are effective indicators of long-term precipitation in South Korea, and examined their relationships based on statistical methods. Monthly total precipitation was collected from a total of 60 meteorological stations, and they were decomposed by ensemble empirical mode decomposition (EEMD) to identify the inherent oscillating patterns or cycles. Cross-correlation analysis and stepwise variable selection were employed to select the significant climate indices at each station. The climate indices that affect the monthly precipitation in South Korea were identified based on the selection frequencies of the selected indices at all stations. The NINO12 indices with four- and ten-month lags and AMO index with no lag were identified as indicators of monthly precipitation in South Korea. Moreover, they indicate meaningful physical information (e.g. periodic oscillations and long-term trend) inherent in the monthly precipitation. The NINO12 indices with four- and ten- month lags was a strong indicator representing periodic oscillations in monthly precipitation. In addition, the long-term trend of the monthly precipitation could be explained by the AMO index. A multiple linear regression model was constructed to investigate the influences of the identified climate indices on the prediction of monthly precipitation. Three identified climate indices successfully explained the monthly precipitation in the winter dry season. Compared to the monthly precipitation in coastal areas, the monthly precipitation in inland areas showed stronger correlation to the identified climate indices.

    2016-01-01

    This study estimated determinants of import demand for refined petroleum products in Nigeria for the period 1984–2013. It employed the autoregressive distributed lag (ARDL) bounds test cointegration method and analysed both long-run and short-run determinants of import demand for total and specific petroleum products. In the long-run, aggregate and sectoral incomes are significant determinants of import of refined kerosene. Further, real effective exchange rate (REER), aggregate income (GDP), manufacturing sector's income, domestic energy production (DEP) and population growth rate (PGR) are drivers of import of refined motor spirit Moreover, REER, DEP and manufacturing sector's income are propellers of import of refined distillate fuel. Also, REER and total output of petroleum products are major drivers of total import of refined petroleum products. Short-run results show that previous period GDP, PGR and manufacturing and service sectors' incomes are determinants of import demand for refined kerosene. Moreover, REER, GDP, previous PGR and manufacturing sector's income exert significant effects on the import of refined motor spirit. Further, significant effects of REER, DEP, previous PGR, domestic output of the product and manufacturing and service sectors' incomes on the import demand for distillate fuel were found. Policy implications of the foregoing are articulated in the paper. - Highlights: •Long-run and short-run drivers of import demand for petroleum products were estimated. •kerosene import is income elastic, gasoline import is income and relative price inelastic. •Exchange rate policies may have diverse effects on import of various petroleum product. •Expanding market size has implication for import demand for petroleum product varieties. •Import demand for petroleum products responds differently to various sectoral incomes.

    Full Text Available Entrepreneurship plays a major role in national economies, being considered one of the main engines of economic growth, and an important contributor to creating new jobs and innovations. Identifying the main determinants of entrepreneurial activity is important for helping the decision makers in adopting adequate measures to support the creation and development of new businesses. The turbulent economic environment in recent years dominated by economic and financial crises, resulting in a reduction in economic growth but also in an increase in unemployment, has led decision makers to turn their attention again to the determinant factors of entrepreneurship. Starting from those stated above, through this paper we aim to investigate the impact of some macroeconomic, individual and business environment-related factors on the dynamics of entrepreneurial activity in 18 European Union (EU countries for a period of 14 years (2002–2015. We use three regression models and we apply panel data fixed effect model approach. The results of our study highlight that inflation rate, foreign direct investments, access to finance and total tax rate are the main macroeconomic determinants of entrepreneurship. Also, we find that all individual business-related factors considered in the analysis have a significant impact on total entrepreneurship rate.

    Owen, Art B

    2001-01-01

    Empirical likelihood provides inferences whose validity does not depend on specifying a parametric model for the data. Because it uses a likelihood, the method has certain inherent advantages over resampling methods: it uses the data to determine the shape of the confidence regions, and it makes it easy to combined data from multiple sources. It also facilitates incorporating side information, and it simplifies accounting for censored, truncated, or biased sampling.One of the first books published on the subject, Empirical Likelihood offers an in-depth treatment of this method for constructing confidence regions and testing hypotheses. The author applies empirical likelihood to a range of problems, from those as simple as setting a confidence region for a univariate mean under IID sampling, to problems defined through smooth functions of means, regression models, generalized linear models, estimating equations, or kernel smooths, and to sampling with non-identically distributed data. Abundant figures offer vi...

    Full Text Available This study investigates five determinants of capital structure (leverage in three subsectors of the Omani Industrial companies (food, construction and chemical listed on Muscat Securities Market for the period 2008–2012. According to available information and literature review, the determinants are profitability measured by return on assets (ROA, risk measured by the standard deviation of return on assets, the size of the company measured by the natural logarithm of total assets, rate of growth measured by the market-book value ratio (P/E and assets tangibility measured by fixed assets to total assets ratio. The capital structure or leverage is measured by total debt ratio. In the industrial sector as whole; the findings of the study indicate that there is a statistically positive association between risk and tangibility and leverage. Also, there is a statistically negative association between growth rate and profitability and leverage, while there is no association with size. Regression analysis indicates that size, tangibility and risk have a statistically significant effect on leverage.

    Full Text Available The goal of this paper is to examine if there are any determinants that systematically influence the capital structure of the companies in the Balkan countries and to determine if any of the existing capital structure theories are relevant in their case. We apply a panel regression on a sample consisting of the largest and most frequently traded joint-stock companies from four countries. The results show that the larger companies and those with higher fixed asset investments exhibit higher leverage, while the more profitable companies and those with more tangible assets use less debt financing. Other variables, such as the concentration of company ownership, the riskiness of its operating profits and the effective tax rates have not been found statistically significant. These results, supported by the robustness tests, have confirmed our expectation that the managers in these countries do not set specific target leverage ratios, but instead follow a particular order in the selection of the sources of financing. In other words, the companies behave in accordance with the pecking order theory, which is a confirmation of our initial hypothesis. The governments of these countries should put more effort on stimulating the use of other sources of financing to relieve the possible excessive company dependence on the banking sector.

    Indonesian banking industry has experienced up and down as can be seen after Pakto '88, in which the number of new banks grew rapidly, but after the 1997-1998 financial crisis, a lot of banks were liquidated due to the deteriorating financial condition and violation of the precautionary principles by bank management. The purpose of this research is to determine and analyze the effects of good corporate governance, information technology, HR competencies on competitive advantage and its implication on marketing performance. The method used in this research was a descriptive survey and explanatory survey with a sample size of 320 respondents, and the data analysis methods used are structural equation modeling. Based on the results of the research, the findings obtained from good corporate governance, information technology, HR competencies have a significant effect on competitive advantage on the performance of marketing. However, when seen in part, competitive advantage has a dominant effect on marketing performance.

  1. Determinants of International Technology Transfer: an Empirical Analysis of the Enterprise Europe Network

    Full Text Available This paper explores the key factors that foster technology transfer within the triad university-industry-government in an international context, i.e., the Enterprise Europe Network (EEN. Based on 71 technological Partnership Agreements (PAs, estimation results indicate that PAs associated to partners that provide their collaborators with the appropriate training in technology transfer-related issues, present substantial past experience in international or technological projects, and participate in extensive networks, are those that achieve better performances in terms of international technology transfer. High levels of formal schooling per se are not a key determinant of international technology transfer; the critical factor is highly educated human resources who receive complementary training in technology transfer issues.

    Research suggests that self-determination skills are positively correlated with factors that have been shown to improve academic achievement, but the direct relationship among self-determination, self-concept, and academic achievement is not fully understood. This study offers an empirical explanation of how self-determination and self-concept affect academic achievement for adolescents with learning disabilities after taking into consideration the covariates of gender, income, and urbanicity. In a nationally representative sample (N = 560), the proposed model closely fit the data, with all proposed path coefficients being statistically significant. The results indicated that there were significant correlations among the three latent variables (i.e., self-determination, self-concept, and academic achievement), with self-determination being a potential predictor of academic achievement for students with learning disabilities. © Hammill Institute on Disabilities 2012.

    Full Text Available In recent years, the changing economic and political environment in Tunisia led to a renewed interest on the drivers of foreign direct investment, given its potential important gains. In this study, we investigated the impact of various factors over the period 1980-2012. In doing this, three categories of determinants were considered: economic, political and sociocultural variables. Empirical findings drawn from the autoregressive distributed lag bounds testing approach show that variation in foreign direct investment inflow in the short-run and long-run is affected by the majority of variables considered, except exchange rate, urban population and gross domestic savings. As a matter of policy, it is essential that government should continue its efforts to create a macroeconomic environment which is attractive to foreign direct investment.

    Full Text Available This paper aims to explore the capital structure of listed Vietnamese companies in an updated context of financial development (the recent situation of domestic equity and debt capital market. By applying Random Effect model for panel data, we analyze 05 firm-specific and 01 country-specific determinants of capital structure based on the data set of 228 firms listed on Ho Chi Minh Stock Exchange during the period 2010 – 2014. The results indicated that The Pecking Order theory better explains the financing behaviors of Vietnamese listed firms. Accordingly, although in recent years, Vietnam’s equity market and corporate debt capital market have evolved considerably, the capital structure of Vietnamese companies are still dominated by the use of short-term financing sources. High-growth firms or large-sized firms still rely heavily on external debt rather than equity issuance while State-owned enterprises (SOE are reported to have positive association with the use of long-term financing sources. This study proposed some recommendations to the policymakers in two dimensions: improving the efficiency and role of capital markets to mitigate the reliance on short-term funds and ensuring that bank finance is allocated on a commercial basis.

    Full Text Available After the implementation of government policies on globalization and liberalization, the consumers have become more critical about the selection of service providers. Consumers are now very much aware of the alternatives available in relation to services and the provider organizations. Expectations of consumers are rising and the provider organizations should be aware of these expectations. The objective of the present study is to examine the factors responsible for helping the consumers to choose mobile telecommunication service provider among the competitors in the market. The primary statistical techniques used in the study are Exploratory Factor Analysis, and Structural Equation Modeling. The data was collected with the help of structured questionnaire consisting of different questions related to demographics, service quality, product quality and availability, promotion and price in order to study perceptions of consumers. In order to examine these above mentioned variables and to derive meaningful conclusions, use of structural equation modelling was imperative. AMOS (Analysis of Moment Structure version 16.0 was employed in the research to test the underlying hypotheses of the study. Results showed that the paths are significantly related to the casual processes. Price was found to be the most important factor followed by product quality and availability, service quality, and promotion in determining perceptions of customers towards mobile telecommunication services. It is expected that the findings of the study may provide meaningful insights to the service providers and contribute in improving their strategies and marketing operations.

    We examine the relationship between three parameters of Type Ia supernovae (SNe Ia): peak magnitude, rise time, and photospheric velocity at the time of peak brightness. The peak magnitude is corrected for extinction using an estimate determined from MLCS2k2 fitting. The rise time is measured from the well-observed B-band light curve with the first detection at least 1 mag fainter than the peak magnitude, and the photospheric velocity is measured from the strong absorption feature of Si II λ6355 at the time of peak brightness. We model the relationship among these three parameters using an expanding fireball with two assumptions: (a) the optical emission is approximately that of a blackbody, and (b) the photospheric temperatures of all SNe Ia are the same at the time of peak brightness. We compare the precision of the distance residuals inferred using this physically motivated model against those from the empirical Phillips relation and the MLCS2k2 method for 47 low-redshift SNe Ia (0.005 Ia in our sample with higher velocities are inferred to be intrinsically fainter. Eliminating the high-velocity SNe and applying a more stringent extinction cut to obtain a “low-v golden sample” of 22 SNe, we obtain significantly reduced scatter of 0.108 ± 0.018 mag in the new relation, better than those of the Phillips relation and the MLCS2k2 method. For 250 km s‑1 of residual peculiar motions, we find 68% and 95% upper limits on the intrinsic scatter of 0.07 and 0.10 mag, respectively.

    2016-09-01

    Full Text Available Friction Stir Processing (FSP has been established as a potential solid state production method to prepare aluminum matrix composites (AMCs. FSP was effectively applied to produce AA6082 AMCs reinforced with various ceramic particles such as SiC, Al2O3, TiC, B4C and WC in this work. Empirical relationships were estimated to predict the influence of FSP process parameters on the properties such as area of stir zone, microhardness and wear rate of AMCs. FSP experiments were executed using a central composite rotatable design consisting of four factors and five levels. The FSP parameters analyzed were tool rotational speed, traverse speed, groove width and type of ceramic particle. The effect of those parameters on the properties of AMCs was deduced using the developed empirical relationships. The predicted trends were explained with the aid of observed macro and microstructures.

    Full Text Available Customer relationship management (CRM is founded based on the value exchange between organization and customers and focuses merely on the value created in this connection. In this paper, the critical success factors are identified for a proper and effective implementation of CRM for an oil distribution company. The proposed survey of this paper identifies some important factors affecting the CRM implementation and determines the most important ones using a survey. The results indicate that there are twelve factors playing the most important roles on the success of CRM. There are CRM strategy, knowledge management in customer relationship, CRM technology, effective strategic committee, management of customer contact channels, customer information management, customer-oriented change management, training programs, strategic communication with staff, staff commitment, integration, and sectional implementation. We categorize the factors into two levels based on the level of their importance. The first level consists of the most important ones include only four items and the other eight items are categorized in level 2.

    2017-07-01

    Aim: Since a system of internal control comprises five inter-related elements, while also taking into consideration that management is ultimately responsible for the internal control in their respective business entities, which is greatly influenced by their managerial conduct, this research study placed focus on determining the relationship which exist between the managerial conduct and the internal control activities evident in South African SMMEs. Setting: This study was conducted in the Cape Metropole, South Africa by obtaining responses from 240 stakeholders of SMMEs: 120 members of management and 120 employees. Methods: In order to achieve the latter, quantitative data were collected through a questionnaire and analysed accordingly through both descriptive statistics and inferential statistics. Results: From the results, a very weak negative statistically significant relationship was identified between the managerial conduct and the internal control activities evident in South African SMMEs. Conclusion: Essentially, management and employees should revisit the internal control activities evident in their respective SMMEs through placing emphasis on those internal control activities which can be built on their control environment.

    Full text: Because of its hardness, abrasion resistance, mechanical strength, corrosion resistance, and good electrical insulation, alumina (AI 2 O 3 ) is a material of high technological and industrial significance. Alumina exists in a variety of metastable structures including the γ, η, θ, K, and χ aluminas, as well as its stable α alumina phase. The crystal structure of the γ-phase in alumina has attracted considerable attention over the past 40 years, with various reports attributing either a cubic or tetragonal structure to this phase. Consensus on the definitive structure of γ-alumina (γ-AI 2 O 3 ) has yet to be reached. Rapid advancement has occurred in the field of computational materials science in recent times. Huge advances in computing power during this period have made ft possible to apply the laws of quantum mechanics to the study of macroscopic properties of real materials at the atomic level. Predicting the properties of materials by theoretical means complements the traditional experimental approaches. This research is directed at determining the structure of γ-Al 2 O 3 using theoretical first principles and empirical computational techniques combined with experimental methods. The purpose of this presentation is to discuss the problems associated with determining the structure of γ-AI 2 O 3 and to outline the methodology being applied to solve it.

    2015-03-01

    Bioethicists and policymakers are increasingly concerned about the effects on health journalism of relationships between journalists and private corporations. The concern is that relationships between journalists and manufacturers of medicines, medical devices, complementary medicines and food can and do distort health reporting. This is a problem because health news is known to have a major impact on the public's health-related expectations and behaviour. Commentators have proposed two related approaches to protecting the public from potential harms arising from industry-journalist interactions: greater transparency and external regulation. To date, few empirical studies have examined stakeholders' views of industry-journalist relationships and how these should be managed. We conducted interviews with 13 journalists and 12 industry employees, and 2 focus groups with consumers. Our findings, which are synthesised here, provide empirical support for the need for greater transparency and regulation of industry-journalist relationships. Our findings also highlight several likely barriers to instituting such measures, which will need to be overcome if transparency and regulation are to be accepted by stakeholders and have their intended effect on the quality of journalism and the actions of news consumers.

    2012-09-01

    Full Text Available The incidence of diet induced diseases such as cancer, high blood pressure, stroke, cardiovascular/heart disease, diabetes, obesity, osteoporosis and malnutrition are rampant in our world today and therefore topical. The practice of nutritional labeling is being advocated as a panacea for this malaise and hence a sizeable number of researches are being undertaken in this direction. Large chunk of these studies are concentrated in the advanced countries. Unfortunately, there is dearth of such studies in developing countries including Nigeria. Consequently, this study sought to empirically determine consumers’ reaction to nutritional labeling of pre-packaged food products in Nigeria. The study was purely descriptive and data collected aptly analyzed through the instrumentality of pertinent statistical tools. Findings show that consumers read, comprehend, trust the authenticity and are significantly aware of nutritional labeling and are able to relate the effects of nutrition information to their health. Not surprising therefore, consumers consciously search for nutrition information, which significantly influence their purchase decisions of these kinds of products. These results hold some implications for both policy-makers and pre-packaged food marketers. Further research should be in areas of quantity and position of disclosure of nutrition information and use of symbols in nutritional labeling in Nigeria.

  1. Determining individual variation in growth and its implication for life-history and population processes using the empirical Bayes method.

    2014-09-01

    Full Text Available The differences in demographic and life-history processes between organisms living in the same population have important consequences for ecological and evolutionary dynamics. Modern statistical and computational methods allow the investigation of individual and shared (among homogeneous groups determinants of the observed variation in growth. We use an Empirical Bayes approach to estimate individual and shared variation in somatic growth using a von Bertalanffy growth model with random effects. To illustrate the power and generality of the method, we consider two populations of marble trout Salmo marmoratus living in Slovenian streams, where individually tagged fish have been sampled for more than 15 years. We use year-of-birth cohort, population density during the first year of life, and individual random effects as potential predictors of the von Bertalanffy growth function's parameters k (rate of growth and L∞ (asymptotic size. Our results showed that size ranks were largely maintained throughout marble trout lifetime in both populations. According to the Akaike Information Criterion (AIC, the best models showed different growth patterns for year-of-birth cohorts as well as the existence of substantial individual variation in growth trajectories after accounting for the cohort effect. For both populations, models including density during the first year of life showed that growth tended to decrease with increasing population density early in life. Model validation showed that predictions of individual growth trajectories using the random-effects model were more accurate than predictions based on mean size-at-age of fish.

  5. Empirical Hamiltonians

    International Nuclear Information System (INIS)

    Peggs, S.; Talman, R.

    1987-01-01

    As proton accelerators get larger, and include more magnets, the conventional tracking programs which simulate them run slower. The purpose of this paper is to describe a method, still under development, in which element-by-element tracking around one turn is replaced by a single man, which can be processed far faster. It is assumed for this method that a conventional program exists which can perform faithful tracking in the lattice under study for some hundreds of turns, with all lattice parameters held constant. An empirical map is then generated by comparison with the tracking program. A procedure has been outlined for determining an empirical Hamiltonian, which can represent motion through many nonlinear kicks, by taking data from a conventional tracking program. Though derived by an approximate method this Hamiltonian is analytic in form and can be subjected to further analysis of varying degrees of mathematical rigor. Even though the empirical procedure has only been described in one transverse dimension, there is good reason to hope that it can be extended to include two transverse dimensions, so that it can become a more practical tool in realistic cases

  6. An empirical method for determination of elemental components of radiated powers and impurity concentrations from VUV and XUV spectral features in tokamak plasmas

    International Nuclear Information System (INIS)

    Lawson, K.; Peacock, N.; Gianella, R.

    1998-12-01

    The derivation of elemental components of radiated powers and impurity concentrations in bulk tokamak plasmas is complex, often requiring a full description of the impurity transport. A novel, empirical method, the Line Intensity Normalization Technique (LINT) has been developed on the JET (Joint European Torus) tokamak to provide routine information about the impurity content of the plasma and elemental components of radiated power (P rad ). The technique employs a few VUV and XUV resonance line intensities to represent the intrinsic impurity elements in the plasma. From a data base comprising these spectral features, the total bolometric measurement of the radiated power and the Z eff measured by visible spectroscopy, separate elemental components of P rad and Z eff are derived. The method, which converts local spectroscopic signals into global plasma parameters, has the advantage of simplicity, allowing large numbers of pulses to be processed, and, in many operational modes of JET, is found to be both reliable and accurate. It relies on normalizing the line intensities to the absolute calibration of the bolometers and visible spectrometers, using coefficients independent of density and temperature. Accuracies of the order of ± 15% can be achieved for the elemental P rad components of the most significant impurities and the impurity concentrations can be determined to within ±30%. Trace elements can be monitored, although with reduced accuracy. The present paper deals with limiter discharges, which have been the main application to date. As a check on the technique and to demonstrate the value of the LINT results, they have been applied to the transport modelling of intrinsic impurities carried out with the SANCO transport code, which uses atomic data from ADAS. The simulations provide independent confirmation of the concentrations empirically derived using the LINT technique. For this analysis, the simple case of the L-mode regime is considered, the chosen

    Khan, Mohammad Niyaz; Yusof, Nor Saadah Mohd; Razak, Norazizah Abdul

    2013-01-01

    The semi-empirical spectrophotometric (SESp) method, for the indirect determination of ion exchange constants (K(X)(Br)) of ion exchange processes occurring between counterions (X⁻ and Br⁻) at the cationic micellar surface, is described in this article. The method uses an anionic spectrophotometric probe molecule, N-(2-methoxyphenyl)phthalamate ion (1⁻), which measures the effects of varying concentrations of inert inorganic or organic salt (Na(v)X, v = 1, 2) on absorbance, (A(ob)) at 310 nm, of samples containing constant concentrations of 1⁻, NaOH and cationic micelles. The observed data fit satisfactorily to an empirical equation which gives the values of two empirical constants. These empirical constants lead to the determination of K(X)(Br) (= K(X)/K(Br) with K(X) and K(Br) representing cationic micellar binding constants of counterions X and Br⁻). This method gives values of K(X)(Br) for both moderately hydrophobic and hydrophilic X⁻. The values of K(X)(Br), obtained by using this method, are comparable with the corresponding values of K(X)(Br), obtained by the use of semi-empirical kinetic (SEK) method, for different moderately hydrophobic X. The values of K(X)(Br) for X = Cl⁻ and 2,6-Cl₂C6H₃CO₂⁻, obtained by the use of SESp and SEK methods, are similar to those obtained by the use of other different conventional methods.

  10. Physical activity and healthy diet: determinants and implicit relationship.

    Tavares, Aida Isabel

    2014-06-01

    People who decide to lose weight by dieting often do so without participating in any associated physical activity. Although some people who participate in sports are unconcerned about their diet, it is generally believed that people who exercise tend to eat a healthy diet and those who do not exercise eat a less healthy diet. There is no clear relationship between the decisions regarding participation in physical activity and eating a healthy diet when choices are taken freely and not influenced by policy factors promoting healthy behaviour. However, these decisions may reveal some common explanatory factors and an implicit link. As such the aim of this study was to identify the common explanatory factors and investigate the existence of an implicit relationship. Econometric estimate - bivariate probit estimation. Using data from the Portuguese National Health Survey, a bivariate probit was undertaken for decisions regarding participation in physical activity and eating a healthy diet. The correlation between the residuals gives information on the implicit relationship between the healthy choices. Common explanatory factors were found between the decisions to eat healthy snacks and participate in physical activity, such as being married. However, holding voluntary private health insurance, smoking, getting older, living alone and unemployment were found to dissuade people from making healthy choices. Positive correlation was found between the residuals of the probit estimations, indicating that other unmeasurable variables have a similar influence on both decisions, such as peer pressure, cultural values, fashion, advertising and risk aversion. Further research is needed to improve understanding of decision making related to participation in physical activity and eating a healthy diet. This will facilitate the design of policies that will make a greater contribution to healthy lifestyles. Copyright © 2014 The Royal Society for Public Health. Published by Elsevier

    2010-01-01

    Full Text Available This paper tries to examine the long run relationships between the aggregate consumer prices and some cost-based components for the Turkish economy. Based on a simple economic model of the macro-scaled price formation, multivariate cointegration techniques have been applied to test whether the real data support the a priori model construction. The results reveal that all of the factors, related to the price determination, have a positive impact on the consumer prices as expected. We find that the most significant component contributing to the price setting is the nominal exchange rate depreciation. We also cannot reject the linear homogeneity of the sum of all the price data as to the domestic inflation. The paper concludes that the Turkish consumer prices have in fact a strong cost-push component that contributes to the aggregate pricing.

    This paper estimates changes in the productivity of the Brazilian electricity distribution sector using Data Envelopment Analysis (DEA) on a panel of 18 firms from 1998 to 2005. The study decomposes the productivity change of these distribution firms in terms of technical efficiency, scale-efficiency and technical progress. This exercise aims to help the understanding of the main determinants of the evolution of productivity, focusing its relationship with the restructuring process implemented in the 1990s. TFP index records a yearly positive growth rate of 1.3% in the whole period under analysis for all firms. Technical change was the main component behind this evolution, with an average growth of 2.1% per year, while technical efficiency presented a yearly negative performance of - 0.8%. The results prove that, in general terms, the incentives generated in the reform process do not seem to have led the firms to behave in a more efficient manner. (author)

    Total suspended solid (TSS) is an important water quality parameter. This study was conducted to test the feasibility of the band combination of hyperspectral sensing for inland turbid water monitoring in Taiwan. The field spectral reflectance in the Wu river basin of Taiwan was measured with a spectroradiometer; the water samples were collected from the different sites of the Wu river basin and some water quality parameters were analyzed on the sites (in situ) as well as brought to the laboratory for further analysis. To obtain the data set for this study, 160 in situ sample observations were carried out during campaigns from August to December, 2005. The water quality results were correlated with the reflectivity to determine the spectral characteristics and their relationship with turbidity and TSS. Furthermore, multiple-regression (MR) and artificial neural network (ANN) were used to model the transformation function between TSS concentration and turbidity levels of stream water, and the radiance measured by the spectroradiometer. The value of the turbidity and TSS correlation coefficient was 0.766, which implies that turbidity is significantly related to TSS in the Wu river basin. The results indicated that TSS and turbidity are positively correlated in a significant way across the entire spectrum, when TSS concentration and turbidity levels were under 800 mg·L(-1) and 600 NTU, respectively. Optimal wavelengths for the measurements of TSS and turbidity are found in the 700 and 900 nm range, respectively. Based on the results, better accuracy was obtained only when the ranges of turbidity and TSS concentration were less than 800 mg·L(-1) and less than 600 NTU, respectively and used rather than using whole dataset (R(2) = 0.93 versus 0.88 for turbidity and R(2) = 0.83 versus 0.58 for TSS). On the other hand, the ANN approach can improve the TSS retrieval using MR. The accuracy of TSS estimation applying ANN (R(2) = 0.66) was better than with the MR approach (R

    2018-03-01

    Full Text Available Few studies have been conducted to explore the role of the institutional environment on the relationship between corporate social responsibility (CSR and operational performance in Korea’s manufacturing industry. Therefore, this study investigates the moderating effects of four institutional uncertainties—law enforcement, regulatory uncertainty, market turbulence and competition intensity—on the relationship between CSR and operational performance. Empirical survey data from 209 Korean manufacturers was collected online and then analyzed through moderated multiple regression analyses. The results show that CSR can significantly affect operational performance, positively moderated by law enforcement and competition intensity, but not by regulatory uncertainty and market turbulence. These results advise that the different institutional environments in which CSR is implemented are particularly important to consider for optimal business operations.

    2018-03-01

    Full Text Available Whereas the measurement of the quality of democracy focused on the rough differentiation of democracies and autocracies in the beginning (e.g. Vanhanen, Polity, Freedom House, the focal point of newer instruments is the assessment of the quality of established democracies. In this context, tensions resp. trade-offs between dimensions of democracy are discussed as well (e.g. Democracy Barometer, Varieties of Democracy. However, these approaches lack a systematic discussion of trade-offs and they are not able to show trade-offs empirically. We address this research desideratum in a three-step process: Firstly, we propose a new conceptual approach, which distinguishes between two different modes of relationships between dimensions: mutual reinforcing effects and a give-and-take relationship (trade-offs between dimensions. By introducing our measurement tool, Democracy Matrix, we finally locate mutually reinforcing effects as well as trade-offs. Secondly, we provide a new methodological approach to measure trade-offs. While one measuring strategy captures the mutual reinforcing effects, the other strategy employs indicators, which serve to gauge trade-offs. Thirdly, we demonstrate empirical findings of our measurement drawing on the Varieties of Democracy dataset. Incorporating trade-offs into the measurement enables us to identify various profiles of democracy (libertarian, egalitarian and control-focused democracy via the quality of its dimensions.

    2013-03-01

    Asian American parenting is often portrayed as highly controlling and even harsh. This study empirically tested the associations between a set of recently developed Korean ga-jung-kyo-yuk measures and several commonly used Western parenting measures to accurately describe Asian American family processes, specifically those of Korean Americans. The results show a much nuanced and detailed picture of Korean American parenting as a blend of Western authoritative and authoritarian styles with positive and-although very limited-negative parenting. Certain aspects of ga-jung-kyo-yuk are positively associated with authoritative style or authoritarian style, or even with both of them simultaneously. They were positively associated with positive parenting (warmth, acceptance, and communication) but not with harsh parenting (rejection and negative discipline). Exceptions to this general pattern were Korean traditional disciplinary practices and the later age of separate sleeping of children. The study discusses implications of these findings and provides suggestions for future research.

    2014-02-01

    This study seeks to integrate two research traditions that lie at the base of the understanding of personality pathology in adolescents. The first research tradition refers to normal personality according to the Five Factor Model (FFM). The second tradition specifies the key feature of personality disorder as the capacity to mentalize, which can be reflected in Social Information Processing (SIP). In a clinical sample of 96 adolescents, the authors investigated response generation, coping strategy, and memories of past frustrating experiences as part of SIP, as mediator in the relationship between personality and personality pathology, and a possible moderating role of personality on the relationship between SIP and personality pathology. The hypothesized mediation, by which the effects of personality dimensions on personality pathology was expected to be mediated by SIP variables, was found only for the effect of Neuroticism, most specifically on BPD, which appeared to be mediated by memories the patients had about past frustrating conflict situations with peers. Some moderating effects of personality on the relationship between SIP variables and personality pathology were found, suggesting that high Agreeableness and sometimes low Neuroticism can buffer this relationship. These results suggest that personality dimensions and social cognitions both independently and together play a role in adolescents' personality pathology.

    Following several decades of rapid economic growth, China has become the largest energy consumer and the greatest emitter of CO{sub 2} in the world. Given the complex development situation faced by contemporary China, Chinese policymakers now confront the dual challenge of reducing energy use while continuing to foster economic growth. This study posits that a better understanding of the relationship between economic growth, energy consumption, and CO{sub 2} emissions is necessary, in order for the Chinese government to develop the energy saving and emission reduction strategies for addressing the impacts of climate change. This paper investigates the cointegrating, temporally dynamic, and casual relationships that exist between economic growth, energy consumption, and CO{sub 2} emissions in China, using data for the period 1990–2012. The study develops a comprehensive conceptual framework in order to perform this analysis. The results of cointegration tests suggest the existence of long-run cointegrating relationship among the variables, albeit with short dynamic adjustment mechanisms, indicating that the proportion of disequilibrium errors that can be adjusted in the next period will account for only a fraction of the changes. Further, impulse response analysis (which describes the reaction of any variable as a function of time in response to external shocks) found that the impact of a shock in CO{sub 2} emissions on economic growth or energy consumption was only marginally significant. Finally, Granger casual relationships were found to exist between economic growth, energy consumption, and CO{sub 2} emissions; specifically, a bi-directional causal relationship between economic growth and energy consumption was identified, and a unidirectional causal relationship was found to exist from energy consumption to CO{sub 2} emissions. The findings have significant implications for both academics and practitioners, warning of the need to develop and implement long

    Full Text Available We are currently witnessing an unprecedented development of new technologies, that offers great opportunities for the modernization of the society, it changes radically the way governments, businesses and citizens have the opportunity to obtain goods and services, the way in which public services are provided that become increasingly important for citizens, the way of obtaining and transmitting information, the way in which business connections are done, the interaction between different communities, etc.. From this point of view we research the way in which public strategies of achievement and implementation of model of e-government are shaped, model which can exploit the opportunities offered by new technologies and can implement roles for the citizen and public policy makers and implicitly of local and regional development. How the public sector should support the implementation of strategies of e-government, to polarize at the highest level all communities of interest, to provide a framework for planning and action across the board, covering local administration, institutions, organizations and government agencies, to empower appropriate training for implementation of IT strategies, can lead to stimulation of generators factors of local and regional development. We also, intend to identify, from carrying out an empirical study in Bihor county, by analysis of 30 public institutions, the degree of implementation of new technologies in public administration, human resources readiness for appropriate use of IT facilities and what level of implementation of e-government in these institutions, in order to outline the main characteristics and determinants of e-government implementation. The present paper is of interest to policy-makers, researchers, local communities through analysis how the introduction of new technology development in developing and implementing public policies, particularly by networking government and e-government, can cause

    The course of cystic fibrosis (CF) progression in children is affected by parent adherence to treatment plans. The Theory of Reasoned Action (TRA) posits that intentions are the best behavioral predictors and that intentions reasonably follow from beliefs ("determinants"). Determinants are affected by multiple "background factors," including spirituality. This study's purpose was to understand whether two parental adherence determinants (attitude towards treatment and self-efficacy) were associated with spirituality (religious coping and sanctification of the body). We hypothesized that parents' attitudes toward treatment adherence are associated with these spiritual constructs. A convenience sample of parents of children with CF aged 3-12 years (n = 28) participated by completing surveys of adherence and spirituality during a regular outpatient clinic visit. Type and degree of religious coping was examined using principal component analysis. Adherence measures were compared based on religious coping styles and sanctification of the body using unpaired t-tests. Collaborative religious coping was associated with higher self-efficacy for completing airway clearance (M = 1070.8; SD = 35.8; P = 0.012), for completing aerosolized medication administration (M = 1077.1; SD = 37.4; P = 0.018), and for attitude towards treatment utility (M = 38.8; SD = 2.36; P = 0.038). Parents who attributed sacred qualities to their child's body (e.g., "blessed" or "miraculous") had higher mean scores for self-efficacy (airway clearance, M = 1058.6; SD = 37.7; P = 0.023; aerosols M = 1070.8; SD = 41.6; P = 0.020). Parents for whom God was manifested in their child's body (e.g., "My child's body is created in God's image") had higher mean scores for self-efficacy for airway clearance (M = 1056.4; SD = 59.0; P = 0.039), aerosolized medications (M = 1068.8; SD = 42.6; P = 0.033) and treatment utility (M

    This document investigates the causal relationship between nuclear energy (NE), pollutant emissions (CO2 emissions), gross domestic product (GDP) and renewable energy (RE) using dynamic panel data models for a global panel consisting of 18 countries (developed and developing) covering the 1990-2013 period. Our results indicate that there is a co-integration between variables. The unit root test suggests that all the variables are stationary in first differences. The paper further examines the link using the Granger causality analysis of vector error correction model, which indicates a unidirectional relationship running from GDP per capita to pollutant emissions for the developed and developing countries. However, there is a unidirectional causality from GDP per capita to RE in the short and long run. This finding confirms the conservation hypothesis. Similarly, there is no causality between NE and GDP per capita.

    Objectives Group prenatal care results in improved birth outcomes in randomized controlled trials, and better attendance at group prenatal care visits is associated with stronger clinical effects. This paper's objectives are to identify determinants of group prenatal care attendance, and to examine the association between proportion of prenatal care received in a group context and satisfaction with care. Methods We conducted a secondary data analysis of pregnant adolescents (n = 547) receiving group prenatal care in New York City (2008-2012). Multivariable linear regression models were used to test associations between patient characteristics and percent of group care sessions attended, and between the proportion of prenatal care visits that occurred in a group context and care satisfaction. Results Sixty-seven groups were established. Group sizes ranged from 3 to 15 women (mean = 8.16, SD = 3.08); 87 % of groups enrolled at least five women. Women enrolled in group prenatal care supplemented group sessions with individual care visits. However, the percent of women who attended each group session was relatively consistent, ranging from 56 to 63 %. Being born outside of the United States was significantly associated with higher group session attendance rates [B(SE) = 11.46 (3.46), p = 0.001], and women who received a higher proportion of care in groups reported higher levels of care satisfaction [B(SE) = 0.11 (0.02), p prenatal care as possible in a group setting, as well as value-based reimbursement models and other incentives to encourage more widespread adoption of group prenatal care.

  1. The risk-return relationship on macroeconomic announcement days : an empirical study of the Norwegian stock market

    OpenAIRE

    Kopperud, Espen; Seljeseth, Camilla Røed

    2016-01-01

    On days when macroeconomic news in Norway is scheduled to be announced, we find a significant and linear relationship between the market beta and average daily excess return. Using Fama-Macbeth regressions, we estimate a negative market risk premium of -1.02% per month (-11.68% annualized). During our sample period from 2001-2015, the realized market risk premium is negative, amounting to -0.20% per month (-2.46% annualized). As a consequence, stocks with higher sensitivity to ...

    Full Text Available The present study aims to highlights the role of work group culture and gender diversity on work group functioning. Gender diversity is an aspect of organizational life and research on the effect of workgroup composition has yielded ambiguous results. The categorization elaboration model (van Knippenberg, De Dreu & Homan, 2004 addresses this issue and suggests examining factors influencing the relationship between work group diversity and work group functioning. The present study proposes that the group gender diversity affects group identification and that this effect is contingent on group norms. 18 work groups in an information technology enterprise were involved. Results confirmed the hypothesis. Theoretical and practical implications are discussed.

    2012-01-01

    Background Previous research has addressed the relationship between customer satisfaction, perceived quality and customer loyalty intentions in consumer markets. In this study, we test and compare three theoretical models of the quality–satisfaction–loyalty relationship in the Chinese healthcare system. Methods This research focuses on hospital patients as participants in the process of healthcare procurement. Empirical data were obtained from six Chinese public hospitals in Shanghai. A total of 630 questionnaires were collected in two studies. Study 1 tested the research instruments, and Study 2 tested the three models. Confirmatory factor analysis was used to assess the scales’ construct validity by testing convergent and discriminant validity. A structural equation model (SEM) specified the distinctions between each construct. A comparison of the three theoretical models was conducted via AMOS analysis. Results The results of the SEM demonstrate that quality and satisfaction are distinct concepts and that the first model (satisfaction mediates quality and loyalty) is the most appropriate one in the context of the Chinese healthcare environment. Conclusions In this study, we test and compare three theoretical models of the quality–satisfaction–loyalty relationship in the Chinese healthcare system. Findings show that perceived quality improvement does not lead directly to customer loyalty. The strategy of using quality improvement to maintain patient loyalty depends on the level of patient satisfaction. This implies that the measurement of patient experiences should include topics of importance for patients’ satisfaction with health care services. PMID:23198824

    The International Classification of Functioning, Disability and Health (ICF) published in 2001 describes the consequences of health conditions with three components of impairments in body structures or functions, activity limitations and participation restrictions. Two of the new features of the conceptual model were the possibility of feedback effects between each ICF component and the introduction of contextual factors conceptualized as moderators of the relationship between the components. The aim of this longitudinal study is to provide empirical evidence of these two kinds of effect. Structural equation modeling was used to analyze data from a French population-based cohort of 548 patients with knee osteoarthritis recruited between April 2007 and March 2009 and followed for three years. Indicators of the body structure and function, activity and participation components of the ICF were derived from self-administered standardized instruments. The measurement model revealed four separate factors for body structures impairments, body functions impairments, activity limitations and participation restrictions. The classic sequence from body impairments to participation restrictions through activity limitations was found at each assessment time. Longitudinal study of the ICF component relationships showed a feedback pathway indicating that the level of participation restrictions at baseline was predictive of activity limitations three years later. Finally, the moderating role of personal (age, sex, mental health, etc.) and environmental factors (family relationships, mobility device use, etc.) was investigated. Three contextual factors (sex, family relationships and walking stick use) were found to be moderators for the relationship between the body impairments and the activity limitations components. Mental health was found to be a mediating factor of the effect of activity limitations on participation restrictions. Copyright © 2015 Elsevier Ltd. All rights

    Full Text Available The study has analyzed the relationship between youth unemployment and economic growth, in the context of Okun law, by using new generation panel data analysis and cointegration tests. In this study, 18 Central and Eastern European country have been selected as subject matter whose youth unemployment rate is above the EU-28 average (25 % for the period 2006-2012. The results show that, if youth unemployment is quite severe; even an exclusive economic growth will not be enough to reduce the youth unemployment rate in the country. It is recommended that the global and country-specific policies which are effective, result-driven on youth (Un employment and labour market issues, should be developed. This study is expected to make a significant contribution to the literature on unemployment and social conflict.

  11. Promoting Supportive Relationships in Youth Programs: A Self-Determination Theory Perspective

    Directory of Open Access Journals (Sweden)

    Mat D. Duerden

    2008-12-01

    Full Text Available Although research suggests that positive contact with non-parental adults is developmentally beneficial for youth; many adolescents do not have access to such relationships. It is important that adults structure existing relationships to optimize positive youth development. Relationships with adults, who support youth’s needs for autonomy, relatedness, and competence, provide youth with scaffolding as they navigate their way through adolescence. Self-Determination Theory offers a straight-forward approach to understanding the elements of contexts that best promote the development of supportive relationships. The purpose of this paper is to review the literature concerning youth-adult relationships, including their associated prevalence and developmental benefits across multiple contexts. These findings are then integrated into a framework of best practices for developing and supporting positive youth relationships with adults within youth program settings. Several theory-based recommendations are offered for youth program administrators and staff who wish to improve youth-adult relationships in their programs.

    Medical establishments and research laboratories use many different type of radionuclides for diagnostic, therapeutic and research purposes. As a final by product large amount of medical waste are produced. This waste represents both biological and radiation hazards, therefore it requires special treatments in both point of view. Biomedical waste is usually best managed on site by decay storage, with minimal transport risk and ALARA (as low as reasonably achieved) exposure levels. The nuclear medical waste has characteristics fundamentally different from the nuclear fuel cycle waste. In medical practice radioactive material is used both in sealed and unsealed form, but major part of the medical waste is produced by using unsealed isotopes of relatively short half-life in most cases less than 100 days and of low specific activity. There are gamma-emitter, position-emitter and pure beta-knitter among these isotopes. The positron-emitter isotopes have usually less than 2 hours half-life; therefore they do not contribute too much to the volume of the radioactive waste since they decay rapidly. Among the γ- and pure β - - emitters there are isotopes with half-life from seconds to several hundred days. Waste containing isotopes with longer half-life contributes mainly to that large volume of waste produced regularly at biomedical sites. On site decay storage requires accurate determination of activity levels. Since quantitative estimation of isotope activity can be difficult where waste packages contain a mixed combination of β - -γ-emitters, segregation at the time of waste production is essential. Accurate identification and quantitative measurement of γ-emitter isotopes is possible with a large volume, reverse electrode, high purity germanium detector even those cases when the isotope emits only low energy gamma photons. However, there is problem with the pure β - emitting isotopes to measure. In biological health care and pharmaceutical research a range of

    Full Text Available One of the most important strategic issues for any enterprise is to create and deliver superior value for its customers and provide enough evidences to convince them not to choose another competitive. In this study, we study the effects of customer value, customer satisfaction and customer loyalty on customer retention. The results indicate that all aspects of the customer value have positive relationships with customer satisfaction but only emotional value has a positive and direct relationship with customer loyalty. The study confirms that while none of customer value aspects has direct and positive relationship with customer retention, both customer satisfaction and customer loyalty positively and directly affect customer retention.

  16. The Relationship between the Generation of Electricity from Renewable Resources and Unemployment: An Empirical Study on the Egyptian Economy

    2016-06-01

    Full Text Available Currently, there is a global trend towards the use of renewable energy resources. This is due to their benefits in terms of economic diversification, job creation, and sustainable development. Given the suffering of the Egyptian economy from the chronic unemployment problem, this paper has adopted the effect of electricity generation from renewable resources on unemployment. It tests the hypothesis which implies an inverse relationship between renewable electricity generation and unemployment rate in Egypt. By using Autoregressive Distributed Lag (ARDL approach to identify the effects in the short and long run during the period (1989-2013, it has been found that the hypothesis was achieved in the long run only. This is due to the fact that renewable energy projects in their establishment stages focus on capital intensity more than labour intensity, but with time both direct and indirect employment effects start to emerge. The econometric results agree in the presence of a significant negative impact of both economic growth and investments on the unemployment rate.

    2017-10-01

    Full Text Available The objective of this study is to investigate the relationship between corporate governance (CG, corporate social responsibility (CSR disclosure, and economic consequences. Broadly speaking, the CG variables consist of ownership structure and management/control structure. The CSR disclosure variables consist of economic, environmental, social, human rights, societal, and product responsibility dimensions. The economic consequences variables consist of bid-ask spreads, trading volume, and share price volatility. The hypotheses are tested using a structural equation modeling analysis with 210 samples of listed firms on the Indonesian Stock Exchange in 2014. The result of this study is as follows: (1 the effect of the proportion of board of directors from the board of commissioners and the audit committee on the CSR disclosure is positive and significant; (2 the effect of the proportion of independent commissioners and the audit committee from the board of commissioners, the audit committee, and the board of directors on CSR disclosure is positive and significant; and (3 the effect of CSR disclosure on trading volume is positive and significant. The main implication of this study is that CSR disclosure activities have a very important role in meeting stakeholders' interests and ensuring the sustainability of the company long-term. In addition, CSR disclosure is considered to be an assertion of a company’s brand differentiation, which means obtaining operating licenses both from the government and society, and the company’s risk management strategy.

    2016-01-01

    Full Text Available In a financial economic scenario in which the corporate survival of small and medium enterprises (SMEs is more conditioned than ever by competitive performance, this paper aims to show that the strategic incorporation of socially responsible actions, more concerned and engaged with stakeholders, contributes to improve the competitiveness of these organizations. Thus, the existence of a direct or mediated relationship between the development of Corporate Social Responsibility (CSR practices and competitive performance has been analyzed from a multi-stakeholder perspective. To accomplish this task, data were collected from a sample of 481 Spanish SMEs and the technique of partial least squares (PLS was used. Outcomes show that the development of CSR practices contributes to increase the competitive performance both directly and indirectly, through the ability of these organizations to manage their stakeholders. This study, therefore, supports the social impact hypothesis and offers evidence about some intangibles such as the relational capacity mediate the causal effect between CSR and competitive performance.

    2015-01-01

    Full Text Available Aims: The aims of this study were to analyze the carbon, hydrogen, nitrogen, sulfur, and oxygen (CHNS-O content of compost derived from Isfahan-Iran municipal solid waste using thermal elemental analyzer and to develop an approximate empirical chemical formula for the organic fraction of the mature compost as a function of its elemental composition. Materials and Methods: The compost samples (1 kg were collected from different parts of the windrows and thoroughly mixed in accordance with standard methods. After drying and milling, each sample was introduced to an elemental analyzer to measure their CHNS-O contents. The moisture content, temperature, and pH value were also monitored in three different windrows during the process. Results: An approximate chemical empirical formula calculated for the organic fraction of the compost was: C 204 H 325 O 85 N 77 S. Conclusion: According to this formula, it appears that the mature compost produced in the site contains higher value of nondegradable nitrogen, which leads to a lower total C/N ratio. Therefore, improving the primary separation of raw material in the composting plant particularly severance of plastic materials can result in an optimum C/N ratio.

  1. Establishing empirical relationships to predict porosity level and corrosion rate of atmospheric plasma-sprayed alumina coatings on AZ31B magnesium alloy

    Directory of Open Access Journals (Sweden)

    D. Thirumalaikumarasamy

    2014-06-01

    Full Text Available Plasma sprayed ceramic coatings are successfully used in many industrial applications, where high wear and corrosion resistance with thermal insulation are required. In this work, empirical relationships were developed to predict the porosity and corrosion rate of alumina coatings by incorporating independently controllable atmospheric plasma spray operational parameters (input power, stand-off distance and powder feed rate using response surface methodology (RSM. A central composite rotatable design with three factors and five levels was chosen to minimize the number of experimental conditions. Within the scope of the design space, the input power and the stand-off distance appeared to be the most significant two parameters affecting the responses among the three investigated process parameters. A linear regression relationship was also established between porosity and corrosion rate of the alumina coatings. Further, sensitivity analysis was carried out and compared with the relative impact of three process parameters on porosity level and corrosion rate to verify the measurement errors on the values of the uncertainty in estimated parameters.

    Adverse drag reactions (ADRs) are estimated to be one of the leading causes of death. Many national and international agencies have set up databases of ADR reports for the express purpose of determining the relationship between drugs and adverse reactions that they cause. We formulate the drug-reaction relationship problem as a continuous optimization problem and utilize C-GRASP, a new continuous global optimization heuristic, to approximately determine the relationship between drugs and adverse reactions. Our approach is compared against others in the literature and is shown to find better solutions

  3. On the empirical determination of positron trapping coefficient at nano-scale helium bubbles in steels irradiated in spallation target

    Krsjak, Vladimir; Kuriplach, Jan; Vieh, Christiane; Peng, Lei; Dai, Yong

    2018-06-01

    In the present work, the specific positron trapping rate of small helium bubbles was empirically derived from positron annihilation lifetime spectroscopy (PALS) and transmission electron microscopy (TEM) studies of Fe9Cr martensitic steels. Both techniques are well known to be sensitive to nanometer-sized helium-filled cavities induced during irradiation in a mixed proton-neutron spectrum of spallation target. Complementary TEM and PALS studies show that positrons are being trapped to these defects at a rate of 1.2 ± 0.8 × 10-14 m3s-1. This suggests that helium bubbles in ferritic/martensitic steels are attractive traps for positrons comparable to mono-vacancies and quantitative analysis of the bubbles by PALS technique is plausible.

    Full Text Available Abstract In spite of the existence of a substantial body of theoretical literature that deals with the intersection of language and culture in the field of English as a foreign/additional (EA/FL language teaching and learning, there are very few empirical studies that investigate this issue with real teachers and learners. Therefore, the objective of this paper is to review some of those empirical studies with a view to informing additional/foreign language pedagogy and teacher education.  For that, the paper, first, summarizes some of the main theoretical issues by discussing the different ways in which the relationship of language and culture has been subjacent to EA/FL pedagogies. Then, the paper shows that there are three different types of language-and-culture-related empirical studies: on coursebooks, on teacher cognition, and on classroom interaction and teacher cognition. A review of these types of studies is made by discussing their main findings. Finally, the paper brings about some implications for the field from the findings of the empirical studies and proposes some topics for further research. Key-words: Culture and language relation. English as an additional/foreign language. Empirical studies.   Resumo Apesar da existência de uma vasta literatura teórica que lida com a interseção entre língua e cultura na área de ensino e aprendizagem do inglês como língua adicional/estrangeira (LA/E, existem poucos estudos empíricos que investigam essa questão com professores e alunos reais.

    This empirical study analyzes the impacts of real income, energy consumption, financial development and trade openness on CO2 emissions for the OECD countries in the Environmental Kuznets Curve (EKC) model by using panel econometric approaches that consider issues of heterogeneity and cross-sectional dependence. Results from the Pesaran CD test, the Pesaran-Yamagata's homogeneity test, the CADF and the CIPS unit root tests, the LM bootstrap cointegration test, the DSUR estimator, and the Emirmahmutoglu-Kose Granger causality test indicate that (i) the panel time-series data are heterogeneous and cross-sectionally dependent; (ii) CO2 emissions, real income, the quadratic income, energy consumption, financial development and openness are integrated of order one; (iii) the analyzed data are cointegrated; (iv) the EKC hypothesis is validated for the OECD countries; (v) increases in openness and financial development mitigate the level of emissions whereas energy consumption contributes to carbon emissions; (vi) a variety of Granger causal relationship is detected among the analyzed variables; and (vii) empirical results and policy recommendations are accurate and efficient since panel econometric models used in this study account for heterogeneity and cross-sectional dependence in their estimation procedures.

In excess of four hundred SME owners, across Australia, were surveyed to test a proposed model and client intimacy variables were found to be the most significant predictors of trust in this important relationship. Offer-related variables, primarily the provision of advisory or performance-related services (rather than conformance-related services, were also found to be significant, however, at a lesser level than client intimacy and relationship variables. The multi-dimensionality of the trust construct was also highlighted.

    Full Text Available Stress plays an important role on job satisfaction in many industries such as accounting. We present an empirical study to examine the impact of job stress on the relationship between the locus of control and accountants' job satisfaction. The study selects a sample of 65 senior and regular accountants who work for thirteen different regional municipalities of city of Mashad located in east part of Iran. The study uses different well-known questionnaire methods such as stress diagnostic survey, locus of control, job satisfaction and employees' performance to perform the study. The results indicate that the stress is on average level for the dominant locos of control factors and job satisfaction and employee performance are in relatively high level. The study also reveals that there are four important factors of role of ambiguity, quantitative overload, career development and handling other workers' responsibilities play important role on job satisfaction and managing career development has important impact on the performance of accountants.

    Using the plausible model of activated carbon proposed by Harris and co-workers and grand canonical Monte Carlo simulations, we study the applicability of standard methods for describing adsorption data on microporous carbons widely used in adsorption science. Two carbon structures are studied, one with a small distribution of micropores in the range up to 1 nm, and the other with micropores covering a wide range of porosity. For both structures, adsorption isotherms of noble gases (from Ne to Xe), carbon tetrachloride and benzene are simulated. The data obtained are considered in terms of Dubinin-Radushkevich plots. Moreover, for benzene and carbon tetrachloride the temperature invariance of the characteristic curve is also studied. We show that using simulated data some empirical relationships obtained from experiment can be successfully recovered. Next we test the applicability of Dubinin's related models including the Dubinin-Izotova, Dubinin-Radushkevich-Stoeckli, and Jaroniec-Choma equations. The results obtained demonstrate the limits and applications of the models studied in the field of carbon porosity characterization

    In the heat transfer studies by forced convection, we have few data about behavior of the fluids in an annular channel heated by a concentric pipe, such date is necessary to know the heat transfer coefficient that establish the interchange of energy and the thermic properties of the fluid with the geometry of the flow. In this work the objective, was to compare some empirical correlations that we needed for determinate the heat transfer coefficient for annular channels, where we obtained similar at the theoretical results of an experiment made by Miller and Benforado. It is important to know such coefficients because we can determinate the heat quantity transmitted to a probe zone, in which we simulate a nuclear fuel element that developed huge heat quantity that must be dispersed in short time. We give theoretical data of the heat forced transfer convection and we analyzed the phenomena in annular channels given some empirical correlations employed by some investigators and we analyzed each one.

  15. Norms and the development of new knowledge as determinants of climate policy. Theoretical considerations and empirical evidence

    Schymura, Michael

    2013-01-01

    The evaluation of long-term effects of climate change in cost-benefit analysis has a long tradition in environmental economics. Since the publication of the ''Stern Review'' in 2006, the debate about the impacts of climate change on the economy and how to compare cost and benefits with each other was revived. The assessment of climate change mitigation policies mainly depends on three not mutually exclusive decisions: First, the discount rate chosen, since costs are incurred today and long-term benefits occur in the future. Second, the uncertainties related to the problem of climate change. This debate was spurred by the literature surrounding Martin Weitzman's ''dismal theorem'', stating that the unknown unknowns could be too large for cost-benefit analysis of long-term climate policy measures. And third, the treatment of technological change in economic models of climate policy. This dissertation contributes to all three mentioned aspects and consists of two interrelated parts. First, I discuss norms, economic welfare criteria, and catastrophic risks in the context of climate change. This first part is closely bound to a discussion of the Stern Review. The second part of the dissertation deals with technological change in its various dimensions and addresses several questions: How is technological change taken into consideration in large-scale environment-economy models? How do certain inputs substitute each other? And how does technology affect energy intensity, a key parameter for meeting targets set by climate policy? Alongside these questions, I also discuss how the production of knowledge takes place in an environmental and resource economics framework and how knowledge production patterns have changed during previous decades. While the first part is of theoretical nature, the second part is mainly empirical. Summing up, I suggest approaches towards long-term evaluation of climate policies and how some methodological drawbacks of the ''Stern Review'' could

    The WHO Commission on the Social Determinants of Health set out an impressive collection of policy proposals on the social determinants of health. However, a serious weakness for securing implementation is the difficulty for policymakers in identifying priorities for action. The objective of this study is to determine a small set of the most influential determinants using existing data and an empirical approach. 45 Indicators from the World Bank's World Development Indicators are selected to measure attainment for the determinants proposed by the Commission. Panel data models of life expectancy at birth for 54 low-income countries over the years 1990-2012 (1188 country-years) are estimated. Each determinant is subjected to a robustness test using Extreme Bound Analysis, to determine the stability of its estimated impact on life expectancy. For 20 robust and significant determinants the magnitude of association with life expectancy is determined. The largest average increases in life expectancy at 14.5 months per capita is associated with a one standard deviation reduction in HIV prevalence among children, followed by advances in gender equality at 9.4 months. Improvements in life expectancy between 6 and 9 months are associated with agricultural production, political stability, access to clean water and sanitation, good governance, and primary school enrolment. Improvements below 6 months are associated with increases in private health expenditure and overseas development assistance, and control of armed conflict and HIV prevalence among men. There is no evidence that national income, public spending on healthcare and education, secondary schooling, terms of international trade, employment, debt service and relief, out-of-pocket expenditures, agricultural ex- or imports, lifestock production, foreign investment, urbanization or environmental degradation are robustly associated with population health. Results provide support for the relevance of some proposed

  18. The Determinants of Actual Migration and the Role of Wages and Unemployment in Albania: an Empirical Analysis

    2008-06-01

    Full Text Available The paper explores the determinants of internal migration in Albania, adopting the Harris-Todaro approach to migration: an internal migration function is estimated using district wage and unemployment rate differentials. The aggregate level wages and unemployment, included in the migration equation, are retrieved from a first stage wage and unemployment equations, estimated controlling for personal characteristics. Moreover, in order to test the predictions of the human capital model of migration, the difference between migrants and non-migrants is emphasized in the estimation. The data source is the "Living Standard Measurement Survey for Albania" (2002, undertaken by the national Institute of Statistics and the World Bank jointly. The results reveal that both wage and unemployment differentials are important determinants of the propensity to migrate in Albania. This conclusion is further emphasized by noting that migrants gain substantially in terms of higher returns to individual characteristics after emigration.

    A method of γ-ray efficiency determination for extended (plane or bulk) samples based on numerical integration of point source efficiency is studied. The proposed method is widely applicable to samples of various shapes and materials. The geometrical factor in the peak efficiency can easily be corrected for by simply changing the integration region, and γ-ray self-absorption is also corrected by the absorption coefficients for the sample matrix.

    Sex workers are disproportionately infected with HIV worldwide. Significant focus has been placed on understanding the structural determinants of HIV and designing related interventions. Although there is growing international evidence that policing is an important structural HIV determinant among sex workers, the evidence has not been systematically reviewed. We conducted a systematic review of quantitative studies to examine the effects of policing on HIV and STI infection and HIV-related outcomes (condom use; syringe use; number of clients; HIV/STI testing and access) among cis and trans women sex workers. Databases included PubMed, Embase, Scopus, Sociological Abstracts, Popline, Global Health (OVID), Web of Science, IBSS, IndMed and WHOLIS. We searched for studies that included police practices as an exposure for HIV or STI infection or HIV-related outcomes. Of the 137 peer-reviewed articles identified for full text review, 14 were included, representing sex workers' experiences with police across five settings. Arrest was the most commonly explored measure with between 6 and 45% of sex workers reporting having ever been arrested. Sexual coercion was observed between 3 and 37% of the time and police extortion between 12 and 28% across studies. Half the studies used a single measure to capture police behaviours. Studies predominantly focused on "extra-legal policing practices," with insufficient attention to the role of "legal enforcement activities". All studies found an association between police behaviours and HIV or STI infection, or a related risk behaviour. The review points to a small body of evidence that confirms policing practices as an important structural HIV determinant for sex workers, but studies lack generalizability with respect to identifying those police behaviours most relevant to women's HIV risk environment.

    Full Text Available Purpose: At present, the Central Government of China pays more attention to the synergistic innovation, and the national strategy policy of “innovation driven development” are made to implementations. Thus, the university plays an important role in the national innovation system, so that how the university gets involved in innovative activities becomes the primary problem of innovation strategy. This paper utilizes Chinese university spin-offs survey data to identify the influence process from institutional innovation and organizational learning to synergistic effect of organization. Design/methodology/approach: Firstly, we found that following the procedural view, each one of these three elements can be divided into two parts. Then, we established structural equation modeling with the connections between these six subdivisions. Secondly, by taking 270 university Spin-offs in China as samples, we verified the fit of the model through statistical data on the questionnaire survey. Thirdly, we analyzed the relationship and influence path of the institutional innovation, organizational learning and synergistic effect. Findings: The results of empirical research show that institutional implementation process is positive correlation on both sides of synergistic effect, and, the intermediary role is obvious that external organizational learning played a regulatory role between institutional innovation synergistic effects. Research limitations/implications: A large-scale questionnaire survey showed that the influence path of “institutions -organization-innovation performance" are existed. Therefore, the system analysis framework should be introduced to the emergence and development of University spin-offs, and further explored the synergistic process of institutional change and organizational evolution. Practical implications: University spin-offs are a mode of university - industry cooperation, and it takes participation in market competition

    Full Text Available This paper explores the contribution of a selection of elements representative of human capital and perception as determinants of entrepreneurship in different stages of the economic cycle. The results confirm the significance of self efficacy, the perception of opportunities, and the fear of failure, and highlight the importance of personal knowledge of entrepreneurs. They remain influential in different economic times in which their analyses have been replicated, although some differences are felt that point to, in contraction periods, a loss of influence of the confidence in one’s own abilities, compared to an increase in the case of judgment on the existence of opportunities in the environment, and in the case of the presence of entrepreneurs in the surrounding context. In contrast, the behavior of the fear of failure, as a barrier to entrepreneurship, remains unchanged in an adverse context with respect to a positive context due to reduced opportunity costs.

    Based on self-determination theory, the current research aimed to explore the potential mediating effect of relatedness need satisfaction on the relationship between charitable behavior and well-being in the Chinese context. Employing a cross-sectional design, participants reported data on the aforementioned variables in Study 1. The results indicated that relatedness need satisfaction mediated the positive relationship between charitable behavior and hedonic well-being and that between charitable behavior and eudaimonic well-being. Subsequently, a field experiment was conducted in Study 2. Participants rated their levels of relatedness need satisfaction and well-being after charitable donation behaviors were primed. We again observed consistent results. Specifically, charitable behavior was positively associated with both hedonic and eudaimonic well-being, and these relationships were mediated by relatedness need satisfaction. The above findings help to clarify the association between charitable behavior and people's subjective feelings (i.e., well-being), and they deepen our understanding of the underlying mechanism from the perspective of psychological needs satisfaction. © 2016 International Union of Psychological Science.

A two-fold comparison of diffusivity determination based on real-time diffusion of Fluorescein isothiocyanate molecular weight (FITC MW markers was conducted using a proposed Fickian-based approach in conjunction with a previously established numerical model developed based on spectrophotometric data. Computed empirical/numerical (Dempiricial/Dnumerical diffusivities characterized by small standard deviations for the 4-, 70- and 500-kDa markers expressed in m2/s are (1.06 × 10−9 ± 1.96 × 10−10/(2.03 × 10−11, (5.89 × 10−11 ± 2.83 × 10−12/(4.6 × 10−12 and (4.89 × 10−12 ± 3.94 × 10−13/(1.27 × 10−12, respectively, with the discrimination between the computation techniques narrowing down as a function of MW. The use of the numerical approach is recommended for fluorescence-based measurements as the standard computational method for effective diffusivity determination until capture rates (minimum 12 fps for the 4-kDa marker and the use of linear instead of polynomial interpolating functions to model temporal intensity gradients have been proven to minimize the extent of systematic errors associated with the proposed empirical method.

    Least squares (LS), Theil's (TS) and weighted total least squares (WTLS) regression analysis methods are used to develop empirical relationships between radium in the ground, radon in soil and radon in dwellings to assist in the post-closure assessment of indoor radon related to near-surface radioactive waste disposal at the Low Level Waste Repository in England. The data sets used are (i) estimated ²²⁶Ra in the < 2 mm fraction of topsoils (eRa226) derived from equivalent uranium (eU) from airborne gamma spectrometry data, (ii) eRa226 derived from measurements of uranium in soil geochemical samples, (iii) soil gas radon and (iv) indoor radon data. For models comparing indoor radon and (i) eRa226 derived from airborne eU data and (ii) soil gas radon data, some of the geological groupings have significant slopes. For these groupings there is reasonable agreement in slope and intercept between the three regression analysis methods (LS, TS and WTLS). Relationships between radon in dwellings and radium in the ground or radon in soil differ depending on the characteristics of the underlying geological units, with more permeable units having steeper slopes and higher indoor radon concentrations for a given radium or soil gas radon concentration in the ground. The regression models comparing indoor radon with soil gas radon have intercepts close to 5 Bq m⁻³ whilst the intercepts for those comparing indoor radon with eRa226 from airborne eU vary from about 20 Bq m⁻³ for a moderately permeable geological unit to about 40 Bq m⁻³ for highly permeable limestone, implying unrealistically high contributions to indoor radon from sources other than the ground. An intercept value of 5 Bq m⁻³ is assumed as an appropriate mean value for the UK for sources of indoor radon other than radon from the ground, based on examination of UK data. Comparison with published data used to derive an average indoor radon: soil ²²⁶Ra ratio shows that whereas the published data are

    This systematic literature review aims to explore the relationship between social determinants of health (SDH), and the rehabilitation of neurological conditions. In particular, the review will consider relationships between social determinants and peoples' attendance and sustained adherence to rehabilitation programs, and motivation regarding neurological rehabilitation. A systematic search of peer-reviewed literature from electronic databases; MEDLINE, Scopus, CINAHL and Informit health, was conducted. Papers published between 2004 and 2014 were considered. Eleven quantitative studies met the inclusion criteria. There was a lack of research addressing SDH and neurological rehabilitation simultaneously. Cardiac and cancer rehabilitation studies reported employment and income, social support, transport, housing and food security as the most frequent SDH factors influencing attendance, sustained adherence and motivation. Given this association, a similar relationship between neurological rehabilitation and SDH is plausible. Rehabilitation of neurological conditions can be a long and difficult process. To pursue optimal outcomes, an individual's social circumstances should be considered. Understanding how SDH interact with neurological rehabilitation may enhance service delivery, thus maximizing the possible rehabilitation outcomes for individuals. Future research that considers SDH and rehabilitation of neurological conditions jointly may benefit service providers and those requiring neurological rehabilitation. Implications for Rehabilitation Social determinants of health are important to consider in the rehabilitation of neurological conditions. Understanding the interplay between the social determinants of health and neurological rehabilitation may enhance the possible outcomes for those requiring rehabilitation. Increased awareness and capacity of health care professionals involved in neurological rehabilitation may hasten momentum towards decreased health

    Although gender differences persist in the receipt of social support and the report of quality of life among people living with HIV/AIDS in Sub-Saharan Africa, the knowledge base on this topic is scant. For those living with HIV/AIDS, women tend to participate more than men in support group activities, but their gender predisposes them to lower quality of life. Therefore, this study seeks to determine what demographic factors moderate the relationship between social support and quality of life among those living with HIV/AIDS in Ghana. A convenience sample of 300 HIV/AIDS support group members who have experience participating in research studies and was obtained for use via cross-sectional design survey in September and October 2013. The Medical Outcome Studies (MOS) HIV Health Survey, the MOS Social Support Survey, and demographic questionnaire instruments were used to assess quality of life, social support, and demographic information respectively. Gender (male) F(3, 296) = 66.04, t = 2.26, p = .024) and having children (have children) (F(5, 294) = 40.34, t = 2.50, p = .013) moderated the relationship between social support and quality of life. Implications of the findings for practice, policy, and research in Ghana and the rest of the developing world were discussed.

    Introduction: Total volume of distribution (V{sub T}) determined by graphical analysis (GA) of PET data suffers from a noise-dependent bias. Likelihood estimation in GA (LEGA) eliminates this bias at the region of interest (ROI) level, but at voxel noise levels, the variance of estimators is high, yielding noisy images. We hypothesized that incorporating LEGA V{sub T} estimation in a Bayesian framework would shrink estimators towards prior means, reducing variability and producing meaningful and useful voxel images. Methods: Empirical Bayesian estimation in GA (EBEGA) determines prior distributions using a two-step k-means clustering of voxel activity. Results obtained on eight [{sup 11}C]-DASB studies are compared with estimators computed by ROI-based LEGA. Results: EBEGA reproduces the results obtained by ROI LEGA while providing low-variability V{sub T} images. Correlation coefficients between average EBEGA V{sub T} and corresponding ROI LEGA V{sub T} range from 0.963 to 0.994. Conclusions: EBEGA is a fully automatic and general approach that can be applied to voxel-level V{sub T} image creation and to any modeling strategy to reduce voxel-level estimation variability without prefiltering of the PET data.

    Trade-offs between functional traits are ubiquitous in nature and can promote species coexistence depending on their shape. Classic theory predicts that convex trade-offs facilitate coexistence of specialized species with extreme trait values (extreme species) while concave trade-offs promote species with intermediate trait values (intermediate species). We show here that this prediction becomes insufficient when the traits translate non-linearly into fitness which frequently occurs in nature, e.g., an increasing length of spines reduces grazing losses only up to a certain threshold resulting in a saturating or sigmoid trait-fitness function. We present a novel, general approach to evaluate the effect of different trade-off shapes on species coexistence. We compare the trade-off curve to the invasion boundary of an intermediate species invading the two extreme species. At this boundary, the invasion fitness is zero. Thus, it separates trait combinations where invasion is or is not possible. The invasion boundary is calculated based on measurable trait-fitness relationships. If at least one of these relationships is not linear, the invasion boundary becomes non-linear, implying that convex and concave trade-offs not necessarily lead to different coexistence patterns. Therefore, we suggest a new ecological classification of trade-offs into extreme-favoring and intermediate-favoring which differs from a purely mathematical description of their shape. We apply our approach to a well-established model of an empirical predator-prey system with competing prey types facing a trade-off between edibility and half-saturation constant for nutrient uptake. We show that the survival of the intermediate prey depends on the convexity of the trade-off. Overall, our approach provides a general tool to make a priori predictions on the outcome of competition among species facing a common trade-off in dependence of the shape of the trade-off and the shape of the trait

    The purpose of this investigation was to determine the differences between gender, physical activity level, and balance in an older adult population. A secondary purpose was to examine the relationship between pedometer-determined ambulatory activity and balance. Forty-six older adults aged 73.7 ± 6.2 years participated in the study. Participants completed the Fullerton Advanced Balance (FAB) Scale and completed a 2-week daily step recording to determine average steps taken per day. Low-level activity participants (7,500 steps/day) in weight, age, and the number of medications reported. Males performed better than females on the two-footed jump test and reactive postural test FAB assessments. High-level activity participants performed significantly better than low-level activity participants on all FAB assessments except stand with feet together and eyes closed, reach forward to object, and walk with head turns.

    This paper investigates the relationship between the working conditions and illness- and injury-related absenteeism of full-time Registered Nurses (RNs) and Licensed Practical Nurses (LPNs). We used 2005 National Survey of the Work and Health of Nurses, which was designed to be representative of nurses employed in nursing in Canada in the fall of 2005. We estimated Negative Binomial regression models separately for RNs and LPNs with health related absenteeism as the dependent variable. The regressors include working conditions, work settings, and shift type/length along with socio-demographic variables. Depression is a significant determinant of absenteeism for both RNs and LPNs. However, workload and lack of respect are significant determinant of absenteeism for LPNs but not for RNs. Both RNs and LPNs working in other setting (physician offices, private nursing educations, educational institutions, governments and associations) will have less absenteeism than those working in hospitals. For LPNs, those working in long-term facility will also have less absenteeism than those working in hospitals. The length and type of shift also has significant effect on absenteeism. Improving working conditions with a resulting reduction in absenteeism might be an economic way to increase the labour supply of nurses without increasing new admissions or new recruits.

    The velocity of movement and applied load affect the production of mechanical power output and subsequently the extent of the adaptation stimulus in strength exercises. We do not know of any known function describing the relationship of power and velocity and load in the bench press exercise. The objective of the study is to find a function modeling of the relationship of relative velocity, relative load and mechanical power output for the bench press exercise and to determine the intensity zones of the exercise for specifically focused strength training of soccer players. Fifteen highly trained soccer players at the start of a competition period were studied. The subjects of study performed bench presses with the load of 0, 10, 30, 50, 70 and 90% of the predetermined one repetition maximum with maximum possible speed of movement. The mean measured power and velocity for each load (kg) were used to develop a multiple linear regression function which describes the quadratic relationship between the ratio of power (W) to maximum power (W) and the ratios of the load (kg) to one repetition maximum (kg) and the velocity (m•s(-1)) to maximal velocity (m•s(-1)). The quadratic function of two variables that modeled the searched relationship explained 74% of measured values in the acceleration phase and 75% of measured values from the entire extent of the positive power movement in the lift. The optimal load for reaching maximum power output suitable for the dynamics effort strength training was 40% of one repetition maximum, while the optimal mean velocity would be 75% of maximal velocity. Moreover, four zones: maximum power, maximum velocity, velocity-power and strength-power were determined on the basis of the regression function.

    We derive the formula of the black hole entropy with a minimal length of the Planck size by counting quantum modes of scalar fields in the vicinity of the black hole horizon, taking into account the generalized uncertainty principle (GUP). This formula is applied to some intriguing examples of black holes - the Schwarzschild black hole, the Reissner-Nordstrom black hole, and the magnetically charged dilatonic black hole. As a result, it is shown that the GUP parameter can be determined by imposing the black hole entropy-area relationship, which has a Planck length scale and a universal form within the near-horizon expansion

    The susceptibility of a tooth to dental caries has been proposed to depend on tooth color. So far there has, however, been no reliable method for tooth color determination. The aims of this study were to evaluate the reliability of an opto-electronic method and to examine the relationship between tooth color and past caries experience. The color of upper right central incisors of 64 school-children was determined using an opto-electronic tri-stimulus color comparator. The intra- and interexaminer reliability of the method was evaluated in vitro and in vivo being 85% and 83%, respectively. To assess the past caries experience the DMFS-index was calculated. Oral hygiene and dietary habits were also assessed. No significant difference in DMFS scores was obtained between the 'white teeth' group and the 'yellow teeth' group. The conclusion is, that the practical importance of possible colorrelated differences in caries resistance is negligible due to the multifaceted nature of dental caries.

    The aim of this study is to determine the relationship between atherosclerosis and periodontopathogenic microorganisms in chronic periodontitis patients following periodontal treatment. A total of 40 patients were included in the study. 20 of these patients diagnosed with atherosclerosis and chronic periodontitis formed the test group. The remaining 20 patients were systemically healthy patients diagnosed with chronic periodontitis and formed the control group. All patients had nonsurgical periodontal treatment. The periodontopathogenic microorganism levels were determined at baseline and at 6 months in microbial dental plaque samples and WBC, LDL, HDL, PLT, fibrinogen, creatinine and hs-CRP levels were determined by blood samples. Statistically significant reduction has been achieved in clinical periodontal parameters following non-surgical periodontal treatment in test and control groups. Following periodontal treatment, WBC, LDL, PLT, fibrinogen, creatinine and hs-CRP levels significantly decreased and HDL levels significantly increased in both test and control groups. Similarly, the periodontopathogenic microorganism levels significantly decreased following periodontal treatment in the test and control groups. A statistically significant positive correlation has been determined between the periodontopathogenic microorganism levels and WBC, LDL, PLT, fibrinogen, creatinine, and hs-CRP levels in the test group. The association between hs-CRP, WBC, LDL, PLT, fibrinogen, creatinine, and the amount of periodontopathogenic microorganisms indicates the possibility that periodontal treatment could decrease the risk atherosclerosis. More studies must be conducted in order for these results to be supported.

    Self-determination theory suggests that when psychological needs for autonomy, competence, and relatedness are met, participants experience more self-determined types of motivation and more positive outcomes. Limited research has examined this mediational role of self-determined motivation in adult physical activity participants, and very few studies have included assessments of relatedness. This study tested the hypothesis that self-determined motivation would mediate the relationship between psychological need fulfillment and affective and behavioral outcomes. Adult dragon boaters (N = 558) between the ages of 19 and 83 completed a questionnaire on motivational aspects of dragon boating. Competence, relatedness, and autonomy all significantly predicted self-determined motivation, but self-determined motivation only partially mediated their relationship with positive and negative affect. These findings demonstrate the importance of all three needs in adult activity motivation and suggest that the relationships between needs, self-determination, and outcomes may be complex.

    As proton accelerators get larger, and include more magnets, the conventional tracking programs which simulate them run slower. At the same time, in order to more carefully optimize the higher cost of the accelerators, they must return more accurate results, even in the presence of a longer list of realistic effects, such as magnet errors and misalignments. For these reasons conventional tracking programs continue to be computationally bound, despite the continually increasing computing power available. This limitation is especially severe for a class of problems in which some lattice parameter is slowly varying, when a faithful description is only obtained by tracking for an exceedingly large number of turns. Examples are synchrotron oscillations in which the energy varies slowly with a period of, say, hundreds of turns, or magnet ripple or noise on a comparably slow time scale. In these cases one may with to track for hundreds of periods of the slowly varying parameter. The purpose of this paper is to describe a method, still under development, in which element-by-element tracking around one turn is replaced by a single map, which can be processed far faster. Similar programs have already been written in which successive elements are ''concatenated'' with truncation to linear, sextupole, or octupole order, et cetera, using Lie algebraic techniques to preserve symplecticity. The method described here is rather more empirical than this but, in principle, contains information to all orders and is able to handle resonances in a more straightforward fashion

    Suicide is highly prevalent among individuals with bipolar disorder and understanding the factors that increase risk for suicide may help to develop targeted interventions to prevent attempts. Impulsivity is thought to be an influential factor associated with suicidality and is also discussed as a key construct of bipolar disorder. The aim of this paper was to systematically review the current evidence to examine the association between impulsivity and suicidality in bipolar disorder. PsycInfo, Medline, and Web of Knowledge databases were searched for articles published up until March 2012. Papers were included if they assessed an adult sample of individuals with bipolar disorders, focused on suicidality (ideation with intent to die, suicide attempts, or completion), and used a validated measure to determine impulsivity. Sixteen papers were identified. Contrary to widespread belief, we found (i) a very inconsistent picture of results including positive, negative, and insignificant associations between impulsivity and suicidality; and (ii) some studies do not take into account important aspects such as state-trait or measurement issues. The link between suicidality and impulsivity is less straightforward than often assumed. Drawing clear conclusions about the association is hampered by factors such as inconsistencies in defining suicidality, measuring impulsivity, and differentiating between impulsivity as a personality trait and impulsivity as a state (e.g., a consequence of substance use or premeditation of the attempt). We suggest that the association is less direct and that psychological models (e.g., Joiner's theory of suicidality) can help foster a more in-depth understanding regarding the relationship. © 2013 John Wiley & Sons A/S.

  15. Determinants of Carboxyhemoglobin Levels and Relationship with Sepsis in a Retrospective Cohort of Preterm Neonates.

    Full Text Available Carboxyhemoglobin levels in blood reflect endogenous carbon monoxide production and are often measured during routine blood gas analysis. Endogenous carbon monoxide production has been reported to be increased during sepsis, but carboxyhemoglobin levels have not been thoroughly evaluated as a biomarker of sepsis. We sought to determine whether carboxyhemoglobin levels were elevated during sepsis in a high risk population of premature neonates. We conducted a retrospective cohort study of 30 infants in two neonatal intensive care units using electronic medical and laboratory records. The majority of infants were extremely premature and extremely low birth weight, and 25 had at least one episode of sepsis. We collected all carboxyhemoglobin measurements during their in-patient stay and examined the relationship between carboxyhemoglobin and a variety of clinical and laboratory parameters, in addition to the presence or absence of sepsis, using linear mixed-effect models. We found that postnatal age had the most significant effect on carboxyhemoglobin levels, and other significant associations were identified with gestational age, hemoglobin concentration, oxyhemoglobin saturation, and blood pH. Accounting for these covariates, there was no significant relationship between the onset of sepsis and carboxyhemoglobin levels. Our results show that carboxyhemoglobin is unlikely to be a clinically useful biomarker of sepsis in premature infants, and raise a note of caution about factors which may confound the use of carbon monoxide as a clinical biomarker for other disease processes such as hemolysis.

    2007-01-01

    Since the early 1990s, the southwestern Alaskan sea otter (Enhydra lutris) population has declined dramatically and the cause has yet to be determined. Population trajectories of large mammals are determined by three factors: survival rate, reproduction rate, and age of first reproduction (AFR). Of these three, AFR should respond first to environmental change. Life history theory predicts that AFR will be older with bottom-up causes (ie, food limitation) and younger when the cause of the decline is top-down (ie, predation), as there is usually abundant resources in this scenario. Traditionally, determining AFR required lethal sampling, which may not always be possible. Work on many mammalian species suggests that the width of annual cementum layers in teeth may decline when breeding begins. If so, examining teeth annuli may provide a nonlethal alternative for determining AFR. Ongoing research has shown this relationship in female sea otters, but male sea otters have not been tested. Sea otter testes and premolar teeth slides were collected by subsistence hunters working with the US Fish and Wildlife Service and the Alaska Sea Otter and Steller Sea Lion Commission from Alaska (1994– 2005). We determined the pattern in cementum annuli thickness for male sea otters across age by measuring annuli at three sites on each of the two slide sections available. We found that cementum annuli layers decreased with age, but found no correlation between cementum annuli and sexual maturity in male sea otters. This lack of correlation may be due to sampling error or different energy expenditures during reproduction for each sex. Since females expend large amounts of energy through gestation and lactation, we hypothesize that the width of female cementum annuli decreases at a much sharper rate when they reach AFR.The southwest Alaskan sea otter population has plummeted up to 90% since the early 1990s and the reason is unknown.1 Declines may be due to a bottom-up source caused by

    The relationship between the proanthocyanidin profile and the perceived astringency was assessed in 13 commercial Tempranillo red wines. The concentration and compositional information were obtained by liquid chromatography with diode array detection coupled to electrospray ionization mass spectrometry after acid-catalyzed depolymerization of wine proanthocyanidins in the presence of excess phloroglucinol. Statistical analysis of the results showed significant correlations between sensory and chemical determinations. Astringency was more affected by the subunit composition than by the total concentration or the average degree of polymerization of wine proanthocyanidins. Higher proportions of epicatechin (EC) subunits in extension positions and gallocatechin (GC) subunits in terminal positions were shown to increase astringency. On the contrary, the amount of epigallocatechin (EGC) in both extension and terminal positions was negatively correlated with the perceived astringency.

    The nature and underlying mechanisms of the observed increased vulnerability to posttraumatic stress disorder (PTSD) in women are unclear. We investigated the genetic overlap of PTSD with anthropometric traits and reproductive behaviors and functions in women. The analysis was conducted using female-specific summary statistics from large genome-wide association studies (GWAS) and a cohort of 3577 European American women (966 PTSD cases and 2611 trauma-exposed controls). We applied a high-resolution polygenic score approach and Mendelian randomization analysis to investigate genetic correlations and causal relationships. We observed an inverse association of PTSD with genetically determined anthropometric traits related to body shape, independent of body mass index (BMI). The top association was related to BMI-adjusted waist circumference (WC adj ; R = -0.079, P body shape and PTSD, which could be mediated by evolutionary mechanisms involved in human sexual behaviors.

    2012-08-01

    Full Text Available Abstract Background This study investigated the relationship between dental occlusion and arm strength; in particular, the imbalance in the jaw can cause loss in arm strength phenomenon. One of the goals of this study was to record the maximum forces that the subjects can resist against the pull-down force on their hands while biting a spacer of adjustable height on the right or left side of the jaw. Then EMG measurement was used to determine the EMG-Force relationship of the jaw, neck and arms muscles. This gave us useful insights on the arms strength loss due to the biomechanical effects of the imbalance in the jaw mechanism. Methods In this study to determine the effects of the imbalance in the jaw to the strength of the arms, we conducted experiments with a pool of 20 healthy subjects of both genders. The subjects were asked to resist a pull down force applied on the contralateral arm while biting on a firm spacer using one side of the jaw. Four different muscles – masseter muscles, deltoid muscles, bicep muscles and trapezoid muscles – were involved. Integrated EMG (iEMG and Higuchi fractal dimension (HFD were used to analyze the EMG signals. Results The results showed that (1 Imbalance in the jaw causes loss of arm strength contra-laterally; (2 The loss is approximately a linear function of the height of the spacers. Moreover, the iEMG showed the intensity of muscle activities decreased when the degrees of jaw imbalance increased (spacer thickness increased. In addition, the tendency of Higuchi fractal dimension decreased for all muscles. Conclusions This finding indicates that muscle fatigue and the decrease in muscle contraction level leads to the loss of arm strength.

For this purpose, the paper uses 55 countries as sample and constructs an NIS index based on a factor analysis of 28 variables. Empirical evidence shows that a firm's strategies, technology infrastructure, government governance, education and linkages are the main components of the NIS. The implications are important for policy-makers and the academia. (Author) 49 refs.

    The possible genomic homologies between three serotypes of human rhinoviruses (HRV 1A, HRV 2, and HRV 14) were investigated. First we confirmed that these viruses were unrelated by the criterion of the absence of common antigenic determinants on the surfaces of the native virions, as detected by cross-neutralization of complementfixation. RNA-RNA hybridization was then examined with purified, highly radioactive, double-stranded, replicative-form RNA and excess single-stranded virion RNA. Single-stranded RNA showed 100% homology with the minus strand from the replicative-form RNA of the same type of virus. HRV 1A, HRV 2, and HRV 14 showed low intertypic homologies; these were not significantly greater than those found between the rhinoviruses and polivirus, which were used as a negative control. The immunological relationship and the RNA homology between HRV 1A and HRV 1B were also examined by the above techniques. It was confirmed that HRV 1A and HRV 1B share some surface determinants and it was also found that HRV 1B RNA shares 70% homology with HRV 1A RNA.

The aim of this study was to determine the association between spirometric results from healthy individuals and their muscle mass assessed by dual energy X-ray absorptiometry (DEXA). A sample of 161 women and 144 men, all healthy non-smokers, was studied. Ages ranged from18 to77years. For each subject, spirometry results and total and regional lean mass values obtained by full body DEXA were recorded. A descriptive analysis of the variables and a regression analysis were performed to study the relationship between spirometric variables and lean body mass, correcting for age and body mass index (BMI). In both sexes all muscle mass variables correlated positively and significantly with spirometric variables, and to a greater extent in men. After partial adjustment of correlations by age and BMI, the factor which best explains the spirometric variables is the total lean body mass in men, and trunk lean body mass in women. In men, muscle mass in the lower extremities is most closely associated with spirometric results. In women, it is the muscle mass of the trunk. In both sexes muscle mass mainly affects FEV 1 .

    The purpose of this study is to determine the rate of prolonged empiric antibiotic therapy in adult ICUs in the United States. Our secondary objective is to examine the relationship between the prolonged empiric antibiotic therapy rate and certain ICU characteristics. Multicenter, prospective, observational, 72-hour snapshot study. Sixty-seven ICUs from 32 hospitals in the United States. Nine hundred ninety-eight patients admitted to the ICU between midnight on June 20, 2011, and June 21, 2011, were included in the study. None. Antibiotic orders were categorized as prophylactic, definitive, empiric, or prolonged empiric antibiotic therapy. Prolonged empiric antibiotic therapy was defined as empiric antibiotics that continued for at least 72 hours in the absence of adjudicated infection. Standard definitions from the Centers for Disease Control and Prevention were used to determine infection. Prolonged empiric antibiotic therapy rate was determined as the ratio of the total number of empiric antibiotics continued for at least 72 hours divided by the total number of empiric antibiotics. Univariate analysis of factors associated with the ICU prolonged empiric antibiotic therapy rate was conducted using Student t test. A total of 660 unique antibiotics were prescribed as empiric therapy to 364 patients. Of the empiric antibiotics, 333 of 660 (50%) were continued for at least 72 hours in instances where Centers for Disease Control and Prevention infection criteria were not met. Suspected pneumonia accounted for approximately 60% of empiric antibiotic use. The most frequently prescribed empiric antibiotics were vancomycin and piperacillin/tazobactam. ICUs that utilized invasive techniques for the diagnosis of ventilator-associated pneumonia had lower rates of prolonged empiric antibiotic therapy than those that did not, 45.1% versus 59.5% (p = 0.03). No other institutional factor was significantly associated with prolonged empiric antibiotic therapy rate. Half of all

This study highlights key determinants of condom use among men who engage in extramarital sex in Nigeria.Methods: Results are based on a subsample of 642 married men from a combined dataset from three waves of the National HIV/AIDS and Reproductive Health Survey (NARHS, a set of multiround nationally representative surveys. Logistic regression was employed to explore possible determinants of condom use in extramarital sex. The motivation, opportunity, and ability model was applied in selecting the determinants.Results: HIV risk-reduction knowledge was found not to be associated with condom use. At the full logistic regression model, being of the Yoruba tribe, having no misconception about HIV transmission, ability to discuss condom use, and ability to wear condoms were the key variables significantly associated with condom use in extramarital sex.Conclusion: Implementing HIV risk-reduction behavior change requires more than knowledge. Behavioral skills in condom use are critical. Intervention efforts should move away from knowledge about risk to concentrate on improving skills on how to discuss condom use and wear condoms correctly.Keywords: married men, extramarital sex, condom use, motivation, opportunity, Nigeria

    Full Text Available Advice provided by financial planners has the potential to impact the financial and emotional well being ofclients. Despite the outcomes of quality financial planning relationships, there is little direct evidence tosupport the importance of ‘relationship quality’ in financial planning. Previous research has emphasised theimportance of relationship quality in psychology, nursing, and business settings. This research investigatesdeterminants of client-professional relationship quality in financial planning, measured in a survey of clientsand financial planners regarding relationship factors of trust, engagement, empowerment, ownership, clientactivity and commitment. Ratings for relationship dimensions were compared between clients and financialplanners, with financial planners found to overestimate their clients’ levels of trust and commitment andunderestimate their client’s levels of empowerment. The relationship dimension of ‘trust’ was found to becritical for client-professional relationship quality.

    Effective interventions require evidence on how individual causal pathways jointly determine disease. Based on the concept of systems epidemiology, this paper develops Diagram-based Analysis of Causal Systems (DACS) as an approach to analyze complex systems, and applies it by examining the contributions of proximal and distal determinants of childhood acute lower respiratory infections (ALRI) in sub-Saharan Africa. Diagram-based Analysis of Causal Systems combines the use of causal diagrams with multiple routinely available data sources, using a variety of statistical techniques. In a step-by-step process, the causal diagram evolves from conceptual based on a priori knowledge and assumptions, through operational informed by data availability which then undergoes empirical testing, to integrated which synthesizes information from multiple datasets. In our application, we apply different regression techniques to Demographic and Health Survey (DHS) datasets for Benin, Ethiopia, Kenya and Namibia and a pooled World Health Survey (WHS) dataset for sixteen African countries. Explicit strategies are employed to make decisions transparent about the inclusion/omission of arrows, the sign and strength of the relationships and homogeneity/heterogeneity across settings.Findings about the current state of evidence on the complex web of socio-economic, environmental, behavioral and healthcare factors influencing childhood ALRI, based on DHS and WHS data, are summarized in an integrated causal diagram. Notably, solid fuel use is structured by socio-economic factors and increases the risk of childhood ALRI mortality. Diagram-based Analysis of Causal Systems is a means of organizing the current state of knowledge about a specific area of research, and a framework for integrating statistical analyses across a whole system. This partly a priori approach is explicit about causal assumptions guiding the analysis and about researcher judgment, and wrong assumptions can be reversed

    The non-linear relationship between provincial economic growth and carbon emissions is investigated by using panel smooth transition regression (PSTR) models. The research indicates that, on the condition of separately taking Gross Domestic Product per capita (GDPpc), energy structure (Es), and urbanisation level (Ul) as transition variables, three models all reject the null hypothesis of a linear relationship, i.e., a non-linear relationship exists. The results show that the three models all contain only one transition function but different numbers of location parameters. The model taking GDPpc as the transition variable has two location parameters, while the other two models separately considering Es and Ul as the transition variables both contain one location parameter. The three models applied in the study all favourably describe the non-linear relationship between economic growth and CO₂ emissions in China. It also can be seen that the conversion rate of the influence of Ul on per capita CO₂ emissions is significantly higher than those of GDPpc and Es on per capita CO₂ emissions.

    This study examined the relationships between self-determination theory (SDT) and theory of planned behavior (TpB) applied to physical activity and exercise behavior (PA&E) in people with chronic pain. Two hundred and eleven adults with chronic musculoskeletal pain (28 males and 183 females, age range 18 to 82 years, mean age 43 years) were recruited from online support groups and clinic networks in the United States. Participants completed SDT measures relevant to PA&E on perceived autonomy support, autonomy, competence, and relatedness, as well as TpB measures relevant to PA&E on intention, attitudes, subjective norms, and perceived behavioral control. Correlational techniques and canonical correlation analysis were performed to examine the relationships and variance within and between theoretical dimensions. Overall, the SDT set accounted for 37% of the TpB variance and the TpB set accounted for 32% of the SDT set variance. The results indicate there are statistical similarities and differences between concepts in SDT and TpB models for PA&E. Using both empirical guidance and clinical expertise, researchers and practitioners should attempt to select and integrate non-redundant and complementary components from SDT, TpB, and other related health behavior theories.

    Full Text Available This research investigated the report choices used for corporate social responsibility (CSR disclosure and the determinants of CSR disclosure of firms listed on the Stock Exchange of Thailand (SET. Since 2014, firms listed on the SET have been required to disclose CSR in either an annual registration statement or a separate report called a sustainability report. It was, therefore, noteworthy to examine the choices these firms chose in the first year of disclosure. The independent variables were hypothesized under three dimensions—shareholder power (government ownership, corporate visibility (firm size and age, and economic performance (profitability and leverage. The results revealed that government-owned firms or large firms are more likely to prefer the sustainability report. In addition, content analysis of CSR disclosure was conducted in three industries: resources, technology and industrial products. Nine CSR components with 43 indices were developed and used to score the disclosure of firms in the three industries. The three highest CSR disclosure items found were declaring concerns of human rights and equality, having a policy of anti-corruption, and generous giving. Moreover, this study found a positive relationship between the number of CSR disclosure items and government ownership; however, neither firm age nor economic performance in the year before was related to the CSR disclosure. These research findings support the proposition of the stakeholder theory affirming that firms carry out CSR activities because of their stakeholders' influence, and regardless of economic performance. In Thailand, stakeholders' influence and corporate visibility are significant determinants of the CSR disclosure.

  17. Reflectance and Thermal Infrared Spectroscopy of Mars: Relationship Between ISM and TES for Compositional Determinations

    2004-01-01

    Reflectance spectroscopy has demonstrated that high albedo surfaces on Mars contain heavily altered materials with some component of hematite, poorly crystalline ferric oxides, and an undefined silicate matrix. The spectral properties of many low albedo regions indicate crystalline basalts containing both low and high calcium pyroxene, a mineralogy consistent with the basaltic SNC meteorites. The Thermal Emission Spectrometer (TES) experiment on the Mars Geochemical Surveyor has acquired critical new data relevant to surface composition and mineralogy, but in a wavelength region that is complementary to reflectance spectroscopy. The essence of the completed research was to analyze TES data in the context of reflectance data obtained by the French ISM imaging spectrometer experiment in 1989. This approach increased our understanding of the complementary nature of these wavelength regions for mineralogic determinations using actual observations of the martian surface. The research effort focused on three regions of scientific importance: Syrtis Major-Isidis Basin, Oxia Palus-Arabia, and Valles Marineris. In each region distinct spatial variations related to reflectance, and in derived mineralogic information and interpreted compositional units were analyzed. In addition, specific science questions related to the composition of volcanics and crustal evolution, soil compositions and pedogenic processes, and the relationship between pristine lithologies and weathering provided an overall science-driven framework for the work. The detailed work plan involved colocation of TES and ISM data, extraction of reflectance and emissivity spectra from areas of known reflectance variability, and quantitative analysis using factor analysis and statistical techniques to determine the degree of correspondence between these different wavelength regions. Identified coherent variations in TES spectroscopy were assessed against known atmospheric effects to validate that the variations

    In the drinking water reservoir Rimov (Southern Bohemia) bacterioplankton was studied during 1983. Special attention was given to the relationships between parameters of bacterial abundance, total and individual activity. Bacterial counts and biomass was assessed and autoradiographic determinations of the proportion of active bacteria incorporating thymidine (Th) and a mixture of amino acids (AA) and total uptake rate of AA were made over a year in the surface layer and during summer stratification from the thermocline and 15 m depth. Specific activity of metabolically active bacteria and specific activity per unit of biomass were negatively correlated with counts of metabolizing cells and with bacterial biomass, respectively. Total and individual heterotrophic activity and counts of bacteria coincided with the changes of phytoplankton biomass, whereas bacteria incorporating Th were more tightly correlated with primary production. The most significant relation of metabolically active bacteria was found to cladoceran biomass. Thus, this part of heterotrophic bacterial activity seems to be stimulated by leakage of dissolved organic matter from phytoplankton being disrupted and incompletely digested by cladocerans rather than from healthy photosynthetizing cells.

    As the gap in income between urban and rural residents bigger and bigger,based on the data from 1978 to 2007,this paper makes an empirical study of the dynamic relation between the fixed assets investment and the difference in income between urban and rural residents. The outcome from the study indicates a long-term balance exists between the investment rate of the fixed assets and the difference in income between urban and rural residents. A short-term deviation from the balance can be adjusted through long time. To a certain extent,city-oriented fixed assets investment policy is the main cause of the big gap in income between urban and rural residents. The big gap in income between urban and rural residents in turn reinforces their social status,thus further strengthening the city-oriented instead of countryside-oriented fixed assets investment policy. Based on that,this paper puts forward some suggestions on adjusting the fixed assets investment policy so as to shorten the difference in income between urban and rural residents and realize the goal of harmonious development between city and countryside.

    It is generally believed that there is an inverse relationship between population growth and vegetation cover. However, reports about vegetation protection and reforestation around the World have been continuously increasing in recent decades, which seems to indicate that this relationship may not be true. In this paper, we have taken 21 cities in Guangdong Province, China as the study area to test the long-term relationship between population growth and vegetation cover, using an AVHRR NDVI data set and the panel cointegrated regression method. The results show that there is a long-term inverted N-shaped curve relationship between population growth and vegetation cover in the region where there are frequent human activities and the influence of climate change on vegetation cover changes is relatively small. The two turning points of the inverted N-shaped curve for the case of Guangdong Province correspond to 2,200 persons · km(-2) and 3,820 persons · km(-2), and they can provide a reference range for similar regions of the World. It also states that the population urbanization may have a negative impact on the vegetation cover at the early stage, but have a positive impact at the later stage. In addition, the Panel Error Correction Model (PECM) is used to investigate the causality direction between population growth and vegetation cover. The results show that not only will the consuming destruction effect and planting construction effect induced by the population growth have a great impact on vegetation cover changes, but vegetation cover changes in turn will also affect the population growth in the long term.

  6. Solar flare hard and soft x ray relationship determined from SMM HXRBS and BCS data

    Toot, G. David

    1989-01-01

    The exact nature of the solar flare process is still somewhat a mystery. A key element to understanding flares if the relationship between the hard x rays emitted by the most energetic portions of the flare and the soft x rays from other areas and times. This relationship was studied by comparing hard x ray light curved from the Hard X-Ray Burst Spectrometer (HXRBS) with the soft x ray light curve and its derivation from the Bent Crystal Spectrometer (BCS) which is part of the X-Ray Polychrometer (XRP), these instruments being on the Solar Maximum Mission spacecraft (SMM). Data sample was taken from flares observed with the above instruments during 1980, the peak of the previous maximum of solar activity. Flares were chosen based on complete coverage of the event by several instruments. The HXRBS data covers the x ray spectrum from about 25 keV to about 440 keV in 15 spectral channels, while the BCS data used covers a region of the Spectrum around 3 angstroms including emission from the Ca XIX ion. Both sets of data were summed over their spectral ranges and plotted against time at a maximum time resolution of around 3 seconds. The most popular theory of flares holds that a beam of electrons produces the hard x rays by bremsstrahlung while the soft x rays are the thermal response to this energy deposition. The question is whether the rate of change of soft x ray emission might reflect the variability of the electron beam and hence the variability of the hard x rays. To address this, we took the time derivative of the soft x ray light curve and compared it to the hard flares, 12 of them showed very closed agreement between the soft x ray derivative and the hard x ray light curve. The other five did not show this behavior but were similar to each other in general soft x ray behavior. Efforts to determine basic differences between the two kinds of flares continue. In addition the behavior of soft x ray temperature of flares was examined.

    Objective: To measure central corneal thickness in Pakistani population and determine its relationship to intra-ocular pressure, age, gender and ethnicity. Study Design: Cross-sectional observation study. Place and Duration of Study: Pakistan Institute of Medical Sciences, Islamabad, Pakistan, between December 2013 and February 2015. Methodology: The right eyes of 1000 cases (496 males and 504 females) were recruited for this study. Inclusion criteria were Pashtun or Punjabi ethnicity, intra-ocular pressure < 22 mmHg, gonioscopically open angles, cup-disk-ratio < 0.5, and age matched normal visual fields. Cases with prior ocular surgery, contact lens use, corneal pathologies, myopia or hypermetropia > ±3.0 diopters, astigmatism of > ±1.0 diopters were excluded. Central corneal thickness was measured using a TopCon non-contact specular microscope. Intra-ocular pressure was measured using Goldmann applanation tonometer. Frequency distribution, test of significance, and regression analysis was carried out using Statistical Package for Social Sciences version 20.0. Result: Mean age was 47.31 ±11.78 years. Ethnic composition was 51.6 percentage (n=516) Pashtun and 48.4 percentage (n=484) Punjabi. The mean central corneal thickness was 503.96 (±12.47) meu m, while the mean intra-ocular pressure was 15.61 (±2.68) mmHg. Regression analysis showed a significant association between central corneal thickness and intra-ocular pressure (p=0.00) and age (p=0.00). A ±100 μ change in central corneal thickness was associated with change in IOP of ±3.30 mmHg, whereas central corneal thickness decreased by 0.12 meu m per year. No significant association could be established between central corneal thickness and ethnicity (p=0.19). Conclusion: Central corneal thickness of the studied races was comparable to non-Caucasians which affects intra-ocular pressure measurements, and decreases with increasing age. No relationship was observed between central corneal thickness and

    Full Text Available Combining social exchange and inducement-contribution theory as our overarching theoretical framework, we examine innovative climate as a boundary condition and organizational trust as a mediating mechanism to explain when and how the employee-organization relationship (EOR is associated with workplace innovative behavior. We conducted a field study using multi-source data to test our hypotheses. The results indicated that creativity positively predicted innovative behavior through organizational trust, and an innovative climate moderated the indirect effect of EOR on innovative behavior via organizational trust. The theoretical and practical implications of these findings and directions for future research are discussed.

  10. The role of need fulfillment in relationship functioning and well-being: a self-determination theory perspective.

    Science.gov (United States)

    Patrick, Heather; Knee, C Raymond; Canevello, Amy; Lonsbary, Cynthia

    2007-03-01

    Self-determination theory posits 3 basic psychological needs: autonomy (feeling uncoerced in one's actions), competence (feeling capable), and relatedness (feeling connected to others). Optimal well-being results when these needs are satisfied, though this research has traditionally focused on individual well-being outcomes (e.g., E. L. Deci & R. M. Ryan, 2000). Three studies examined the role of need fulfillment in relationship functioning and well-being. Study 1 found that fulfillment of each need individually predicted both individual and relationship well-being, with relatedness being the strongest unique predictor of relationship outcomes. Study 2 found that both partners' need fulfillment uniquely predicted one's own relationship functioning and well-being. Finally, in Study 3, the authors used a diary recording procedure and tested a model in which the association between need fulfillment and relationship quality was mediated by relationship motivation. Those who experienced greater need fulfillment enjoyed better postdisagreement relationship quality primarily because of their tendency to have more intrinsic or autonomous reasons for being in their relationship. 2007 APA, all rights reserved

    The Half Value Layer (HVL) of copper and aluminium for special standard x-rays beams (emitted from x-ray machine type Philips MGC30 used in Secondary Standard Dosimetry Laboratory (SSDL) have been determined. The relationship between HVL values of aluminium and copper was established. This relationship can be represented by a non-linear fit. These results are valuable for x-ray workers especially those working in the field of radiation calibration for beam energy determination. Using the results of this study, unavailable thickness of one metal can be replaced by the corresponding thickness of the other metal, for filtration and measurement of x-ray beam. (Authors)

    Full Text Available Chlorophyll-a concentration is one of the main indicators of inland waters quality. Using CHRIS/PROBA images and in situ data obtained in four lakes in Colombia and Spain, we obtained empirical models for the estimation of chlorophyll-a concentration, which can be directly applied to future images of MSI Sentinel-2 and OLCI Sentinel-3 sensors. The models, based on spectral band indices, were validated with data from the hyperspectral sensor HICO, onboard of the International Space Station.

  13. Actual factors to determine cross-currency basis swaps: An empirical study on US dollar/Japanese yen basis swap rates from the late 1990s

    Cross-currency basis swap rates that exchange US-dollar (USD) and Japanese-yen (JPY) LIBORs have fluctuated since the late 1990s. It is increasingly important for market participants to figure out such swap rates, but there have not been many empirical studies about actual markets. This study addresses factors of USD/JPY swap rates from the late 1990s to the present, and demonstrates that differences in credit risk premiums, forward exchange rates and assets swaps of foreign investors from JP...

    Do cultural values enhance financial and subjective well-being (SWB)? Taking a multidisciplinary approach, we meta-analytically reviewed the field, found it thinly covered, and focused on individualism. In counter, we collected a broad array of individual-level data, specifically an Internet sample of 8,438 adult respondents. Individual SWB was most strongly associated with cultural values that foster relationships and social capital, which typically accounted for more unique variance in life satisfaction than an individual's salary. At a national level, we used mean-based meta-analysis to construct a comprehensive cultural and SWB database. Results show some reversals from the individual level, particularly masculinity's facet of achievement orientation. In all, the happy nation has low power distance and low uncertainty avoidance, but is high in femininity and individualism, and these effects are interrelated but still partially independent from political and economic institutions. In short, culture matters for individual and national well-being.

    Full Text Available In a. sample made up of 3312 boards of scots pine (pinus sylvestris and 3318 boards of laricio pine pinus nigra Van Saltzmannii, both of Spanish provenance, and ranging in size from 100x40x2500 mm to 200x70x4500 mm, previously tested in accordance with the procedure set forth in UNE EN 408 standard, the relationships between the grade determining properties considered in the UNE EN 338 standard (bending strength, global and local modulus of elasticity in bending, density are studied. In addition to these variables, the modulus of elasticity was also considered, calculated by means of the measuring of the transmission speed of an ultrasonic pulse generated by a Sylvatest device. The global modulus of elasticity calculated by measuring the deformation at the neutral axis seems to be the best predictor of the ultimate bending strength, while the local modulus of elasticity proves to be difficult to obtain, and has a lower predictive quality, and so its elimination is suggested. The need to consider one single testing procedure to determine the global modulus of elasticity is also analyzed, along with the convenience of carrying out further studies regarding the use of ultrasonic techniques in order to predict the modulus of elasticity, due to the fact that the systems available are not sufficiently precise.

    Hansson, H; Lagerkvist, C J

    2016-01-01

    In this study, we sought to identify empirically the types of use and non-use values that motivate dairy farmers in their work relating to animal welfare of dairy cows. We also sought to identify how they prioritize between these use and non-use values. Use values are derived from productivity considerations; non-use values are derived from the wellbeing of the animals, independent of the present or future use the farmer may make of the animal. In particular, we examined the empirical content and structure of the economic value dairy farmers associate with animal welfare of dairy cows. Based on a best-worst scaling approach and data from 123 Swedish dairy farmers, we suggest that the economic value those farmers associate with animal welfare of dairy cows covers aspects of both use and non-use type, with non-use values appearing more important. Using principal component factor analysis, we were able to check unidimensionality of the economic value construct. These findings are useful for understanding why dairy farmers may be interested in considering dairy cow welfare. Such understanding is essential for improving agricultural policy and advice aimed at encouraging dairy farmers to improve animal welfare; communicating to consumers the values under which dairy products are produced; and providing a basis for more realistic assumptions when developing economic models about dairy farmers' behavior.

    Salaris, Maurizio; Serenelli, Aldo; Weiss, Achim; Miller Bertolami, Marcelo

    2009-01-01

    Using the most recent results about white dwarfs (WDs) in ten open clusters, we revisit semiempirical estimates of the initial-final mass relation (IFMR) in star clusters, with emphasis on the use of stellar evolution models. We discuss the influence of these models on each step of the derivation. One intention of our work is to use consistent sets of calculations both for the isochrones and the WD cooling tracks. The second one is to derive the range of systematic errors arising from stellar evolution theory. This is achieved by using different sources for the stellar models and by varying physical assumptions and input data. We find that systematic errors, including the determination of the cluster age, are dominating the initial mass values, while observational uncertainties influence the final mass primarily. After having determined the systematic errors, the initial-final mass relation allows us finally to draw conclusions about the physics of the stellar models, in particular about convective overshooting.

    It has been reported that students are already accumulating substantial debt from higher education fees and their spending habit are at a critical stage. These situations cause the youngsters facing bankruptcy if they cannot improve their saving habit. Many researches have acknowledged that the determinants of saving habit include financial management, parental socialization, peer influence, and self-control. However, there remains a need for investigating the relationship between these determinants in order to avoid bankruptcy among youngsters. The objectives of this study are to investigate the relationship between saving habit determinants and to generate a statistical model based on the determinants of saving habit. Data collection method used is questionnaire and its scope is undergraduate students of UiTM Negeri Sembilan, Kampus Seremban. Samples are chosen by using stratified probability sampling technique and cross-sectional method is used as the research design. The results are then analysed by using descriptive analysis, reliability test, Pearson Correlation, and Multiple Linear Regression analysis. It shows that saving habit and self-control has no relationship. It means that students with less self-control tend to save less. A statistical model has been generated that incorporated this relationship. This study is significant to help the students save more by having high self-control.

    The decoupling elasticity decomposition quantitative model of energy-related carbon emission in Guangdong is established based on the extended Kaya identity and Tapio decoupling model for the first time, to explore the decoupling relationship and its internal mechanism between energy-related carbon emission and economic growth in Guangdong. Main results are as follows. (1) Total production energy-related carbon emissions in Guangdong increase from 4128 × 10⁴ tC in 1995 to 14396 × 10⁴ tC in 2011. Decoupling elasticity values of energy-related carbon emission and economic growth increase from 0.53 in 1996 to 0.85 in 2011, and its decoupling state turns from weak decoupling in 1996-2004 to expansive coupling in 2005-2011. (2) Land economic output and energy intensity are the first inhibiting factor and the first promoting factor to energy-related carbon emission decoupling from economic growth, respectively. The development speeds of land urbanization and population urbanization, especially land urbanization, play decisive roles in the change of total decoupling elasticity values. (3) Guangdong can realize decoupling of energy-related carbon emission from economic growth effectively by adjusting the energy mix and industrial structure, coordinating the development speed of land urbanization and population urbanization effectively, and strengthening the construction of carbon sink.

    Full Text Available The purpose of this paper is to investigate the relationship between the usage and perceived credibility of several sources of information domestic travelers take into consideration when gathering information on potential accommodation providers, on one hand, and, respectively, travelers’ demographic characteristics, on the other hand. After analyzing data from an online questionnaire based study conducted among a sample of 346 young Romanian Facebook users (between 19 and 35 years old, the results showed that, considering types of information sources usually taken into consideration, personal sources and Facebook are more frequently found among travelers with a lower income, travel agencies are more frequently mentioned as usual sources of information among older travelers and among those with a higher level of education, while women are more inclined than men to use leaflets and booklets as sources of information on accommodation providers. Moreover, the research showed that the higher the income, the higher the level of perceived credibility of online portals is. Also, travel agencies and personal sources are more frequently mentioned among the most credible sources by women, than by men, while men are slightly more confident than women in online banners and blogs. The findings can be very useful and relevant from a practical perspective, especially for communication and promotion purposes in the hospitality industry.

  8. Umayyad Relations with Byzantium Empire

    Full Text Available This research investigates the political and military relations between Umayyad caliphates with the Byzantine Empire. The aim of this research is to clarify Umayyad caliphate’s relations with the Byzantine Empire. We know that these relations were mostly about war and fight. Because there were always intense conflicts between Muslims and the Byzantine Empire, they had to have an active continuous diplomacy to call truce and settle the disputes. Thus, based on the general policy of the Umayyad caliphs, Christians were severely ignored and segregated within Islamic territories. This segregation of the Christians was highly affected by political relationships. It is worthy of mentioning that Umayyad caliphs brought the governing style of the Sassanid kings and Roman Caesar into the Islamic Caliphate system but they didn’t establish civil institutions and administrative organizations.

    In this cross-sectional study, we conducted a comprehensive assessment of all articular elements that could be measured using knee MRI. We assessed the association of pathological change in multiple articular structures involved in the pathoanatomy of osteoarthritis. Knee MRI scans from patients over 45 years old were assessed using a semi-quantitative knee MRI assessment form. The form included six distinct elements: cartilage, bone marrow lesions, osteophytes, subchondral sclerosis, joint effusion and synovitis. Each type of pathology was graded using an ordinal scale with a value of zero indicating no pathology and higher values indicating increasingly severe levels of pathology. The principal dependent variable for comparison was the mean cartilage disease score (CDS), which captured the aggregate extent of involvement of articular cartilage. The distribution of CDS was compared to the individual and cumulative distributions of each articular element using the Chi-squared test. The correlations between pathological change in the various articular structures were assessed in a Spearman correlation table. Data from 140 patients were available for review. The cohort had a median age of 61 years (range 45-89) and was 61% female. The cohort included a wide spectrum of OA severity. Our analysis showed a statistically significant trend towards pathological change involving more articular elements as CDS worsened (p-value for trend osteophytes (p-value for trend subchondral sclerosis (p = 0.009), but not joint effusion or synovitis. There was a moderate correlation between cartilage damage, osteophytes and BMLs as well as a moderate correlation between joint effusion and synovitis. However, cartilage damage and osteophytes were only weakly associated with synovitis or joint effusion. Our results support an inter-relationship of multiple articular elements in the pathoanatomy of knee OA. Prospective studies of OA pathogenesis in humans are needed to correlate these

    Two decades of research indicate causal associations between social relationships and mortality, but important questions remain as to how social relationships affect health, when effects emerge, and how long they last. Drawing on data from four nationally representative longitudinal samples of the US population, we implemented an innovative life course design to assess the prospective association of both structural and functional dimensions of social relationships (social integration, social support, and social strain) with objectively measured biomarkers of physical health (C-reactive protein, systolic and diastolic blood pressure, waist circumference, and body mass index) within each life stage, including adolescence and young, middle, and late adulthood, and compare such associations across life stages. We found that a higher degree of social integration was associated with lower risk of physiological dysregulation in a dose-response manner in both early and later life. Conversely, lack of social connections was associated with vastly elevated risk in specific life stages. For example, social isolation increased the risk of inflammation by the same magnitude as physical inactivity in adolescence, and the effect of social isolation on hypertension exceeded that of clinical risk factors such as diabetes in old age. Analyses of multiple dimensions of social relationships within multiple samples across the life course produced consistent and robust associations with health. Physiological impacts of structural and functional dimensions of social relationships emerge uniquely in adolescence and midlife and persist into old age.

    Prenatal lead exposure is a health hazard that may cause cognitive development impairments and other adverse effects in children. We conducted a cross sectional study analyzing cord blood lead levels (CBLL) of newborns and their relationship with maternal determinants of lead exposure. Mothers answered a questionnaire about socio-demographic, lifestyle habits and environmental characteristics. We used Mann-Whitney's test to compare CBLL geometrical means (GM) corresponding to the presence or absence of each lead exposure determinant, and Chi square test to study the relationship between CBLL and maternal lead exposure determinants. A total of 159 newborns participated in the study. CBLL GM was 2.1 μg/dL; and 25% of the participants had a measurable CBLL (LOQ=3.3 μg/dl). Although the participants had several determinants of lead exposure, we only found a significant relationship with inside household determinants, such as presence of lead piping (p=0.026), unplastered walls (p=0.046) and peeling paint (p=0.048). Our results show that CBLL GM was similar to that reported in several studies conducted around the world. However, 25% of the participants might have some degree of risk for lead poisoning.

  12. A comparison of the performance of a fundamental parameter method for analysis of total reflection X-ray fluorescence spectra and determination of trace elements, versus an empirical quantification procedure

    1998-01-01

    The performance has been compared of two different quantification methods — namely, the commonly used empirical quantification procedure and a fundamental parameter approach — for determination of the mass fractions of elements in particulate-like sample residues on a quartz reflector measured in the total reflection geometry. In the empirical quantification procedure, the spectrometer system needs to be calibrated with the use of samples containing known concentrations of the elements. On the basis of intensities of the X-ray peaks and the known concentration or mass fraction of an internal standard element, by using relative sensitivities of the spectrometer system the concentrations or mass fractions of the elements are calculated. The fundamental parameter approach does not require any calibration of the spectrometer system to be carried out. However, in order to account for an unknown mass per unit area of a sample and sample nonuniformity, an internal standard element is added. The concentrations/mass fractions of the elements to be determined are calculated during fitting a modelled X-ray spectrum to the measured one. The two quantification methods were applied to determine the mass fractions of elements in the cross-sections of a peat core, biological standard reference materials and to determine the concentrations of elements in samples prepared from an aqueous multi-element standard solution.

    2015-06-01

    A statistical generalization of microeconomics has been made in Baaquie (2013), where the market price of every traded commodity, at each instant of time, is considered to be an independent random variable. The dynamics of commodity market prices is modeled by an action functional-and the focus of this paper is to empirically determine the action functionals for different commodities. The correlation functions of the model are defined using a Feynman path integral. The model is calibrated using the unequal time correlation of the market commodity prices as well as their cubic and quartic moments using a perturbation expansion. The consistency of the perturbation expansion is verified by a numerical evaluation of the path integral. Nine commodities drawn from the energy, metal and grain sectors are studied and their market behavior is described by the model to an accuracy of over 90% using only six parameters. The paper empirically establishes the existence of the action functional for commodity prices that was postulated to exist in Baaquie (2013).

    Genetic determinism can be described as the attribution of the formation of traits to genes, where genes are ascribed more causal power than what scientific consensus suggests. Belief in genetic determinism is an educational problem because it contradicts scientific knowledge, and is a societal problem because it has the potential to foster intolerant attitudes such as racism and prejudice against sexual orientation. In this article, we begin by investigating the very nature of belief in genetic determinism. Then, we investigate whether knowledge of genetics and genomics is associated with beliefs in genetic determinism. Finally, we explore the extent to which social factors such as gender, education, and religiosity are associated with genetic determinism. Methodologically, we gathered and analyzed data on beliefs in genetic determinism, knowledge of genetics and genomics, and social variables using the "Public Understanding and Attitudes towards Genetics and Genomics" (PUGGS) instrument. Our analyses of PUGGS responses from a sample of Brazilian university freshmen undergraduates indicated that (1) belief in genetic determinism was best characterized as a construct built up by two dimensions or belief systems: beliefs concerning social traits and beliefs concerning biological traits; (2) levels of belief in genetic determination of social traits were low, which contradicts prior work; (3) associations between knowledge of genetics and genomics and levels of belief in genetic determinism were low; and (4) social factors such as age and religiosity had stronger associations with beliefs in genetic determinism than knowledge. Although our study design precludes causal inferences, our results raise questions about whether enhancing genetic literacy will decrease or prevent beliefs in genetic determinism.

    The remineralization effect of fluoride has been measured by surface microhardness on tooth enamel. The purpose of this study was to investigate the relationship between microhardness and fluorine concentration on tooth enamel. Twelve sound bovine enamel specimens were prepared and immersed in 0.05% NaF solution for 1, 3, 6, 24 and 36 hours, respectively. The concentration of fluorine in specimens were measured by PIGE analysis and surface microhardness of each specimen was measured by surface microhardness tester. Fluorine concentration was increased by immersing time. There was no change in microhardness of each specimen by fluorine content. The results of this study suggest that there was no relationship between the fluorine concentration and surface microhardness in sound tooth enamel. PIGE analysis can be used effectively to assess the remineralization effect of fluorine content in tooth enamel. (author)

    The shear-thinning low, medium and high-viscosity fiber preparations (0.15-1.05 % psyllium husk, 0.07-0.6 % guar gum, 0.15-1.20 % gum tragacanth, 0.1-0.8 % gum karaya, 0.15-1.05 % high-viscosity Carboxy Methyl Cellulose and 0.1-0.7 % xanthan gum) showed that the consistency coefficient (k) was a function of concentration, the relationship being exponential (R(2), 0.87-0.96; P flow behaviour index (n) (except for gum karaya and CMC) was exponentially related to concentration (R(2), 0.61-0.98). The relationship between k and sensory viscosity rating (SVR) was essentially linear in nearly all cases. The SVR could be predicted from the consistency coefficient using the regression equations developed. Also, the relationship of k with fiber concentration would make it possible to identify the concentration of a particular gum required to have desired consistency in terms of SVR.

Specifically, the consequences and predictors of following traditional gender roles of female submissiveness and male dominance in sexual relationships is examined. Despite evidence that men and women's sexual roles are becoming more egalitarian over time, empirical evidence suggests that the traditional sexual roles continue to dominate heterosexual relations. This article explores whether the sexual context is one in which both men and women feel particularly compelled to engage in gender stereotypic behavior, and why. In addition, this article reports on research that finds that men and women have automatic associations between sexuality and power that reinforce their gender stereotypic behavior in sexual contexts. The negative effects of traditional gender-role adherence for women's sexual problems and satisfaction is demonstrated. This article concludes that traditional sexual scripts are harmful for both women's and men's ability to engage in authentic, rewarding sexual expression, although the female submissive role may be particularly debilitating. Future directions of research are suggested, including interventions to reduce women's adherence to the sexually submissive female script.

    We estimate a structural dynamic model of the determinants of obesity. In addition to including many of the well-recognized endogenous factors mentioned in the literature as obesity determinants, we also model the individual’s residential location as a choice variable, which is the main contribution of this paper to the literature. This allows us to control for an individual's self-selection into communities that possess the types of amenities in the built environment, which in turn affect th...

  4. Relationship between the pitch of modulation collimators and the determination accuracy of source positions

    The celestial positions of X-ray bursters and gamma-ray burst sources can be accurately determined with rotating modulation collimators which possess wide fields of view and also high angular resolutions. Since the determination accuracy is dependent on the signal to noise ratio of incident photons, the distribution of signal power is analysed and the optimum pitch of the modulation collimator for a burst of a given size is discussed.
