Abstract:

In this paper, we consider a Cournot duopoly, in which any firm does not know the marginal costs of production of the other player, as a Bayesian game. In our game, the marginal costs depend on two infinite continuous sets of states of the world. We shall study, before the general case, an intermediate case in which only one player, the second one, shows infinitely many types. Then, we shall generalize to the case in which both players show infinitely many types depending on the marginal costs, where the marginal costs are given by the nature and each actual marginal cost is known only by the respective player. We find, in both cases, the general Nash equilibrium.

Abstract:

Under the assumption that agricultural cooperative is a form of vertical integration, this paper, using conjectural variations, solves the profit-maximizing problem faced by the members in the multi-plant firm model in which they are vertically integrated with the agricultural cooperative. The average principle, the marginal principle, and the linear combination principle are derived for the competitive behaviour, collusive behaviour, and Cournot behaviour, respectively. The Nash equilibrium and economic efficiency in the cooperative system are then discussed. Finally, the model is numerically solved in an illustration. The marginal principle ensures the cooperative system to remain socially optimal in the competitive market.

Abstract:

In this paper, we propose a new supervised learning algorithm, which is named the Generalized Marginal Fisher Analysis (GMFA), to utilize the advantages of the Marginal Fisher Analysis (MFA) and the Generalized Singular Value Decomposition (GSVD) techniques for face recognition. The experimental results on several standard face databases demonstrate that GMFA outperforms LDA/Fisherface, LDA/GSVD and MFA.

Abstract:

When consumers have heterogeneous perceptions about product quality, traditional parametric methods may not provide accurate marginal valuation estimates of a product's characteristics. A quantile regression framework can be used to estimate valuations of product characteristics when quality perceptions are not homogeneous. Semiparametric quantile regressions provide identification and quantification of heterogeneous marginal valuation effects across a conditional price distribution. Using purchase price data from a bull auction, we show that there are nonconstant marginal valuations of bull carcass and growth traits. Improved understanding of product characteristic valuations across differentiated market segments can help producers develop more cost-effective management strategies.

Abstract:

Purpose – The purpose of this paper is to estimate survey-based values of the elasticity of marginal social valuation of income, an important welfare parameter in cost-benefit analysis. Design/methodology/approach – A model relating equity welfare weights to income is developed, and iso-elasticity of marginal valuation of income is tested using survey data obtained from a sample of Turkish politicians who are instrumental in policy making. Findings – Based on the survey feedback, formal statistical testing indicates that Turkish politicians, regardless of party allegiance, reveal preferences consistent with an iso-elastic marginal social valuation of income. The estimated value of the elasticity measure is close to unity for each of the political parties. Originality/value – The originality of the paper is in terms of the survey method used to obtain from Turkish politicians estimates of the marginal social valuation of income. This welfare parameter is needed in the calculation of both social discount rates and welfare weights. The paper will be of interest to academics in the field of welfare economics as well as to practitioners involved in the appraisal of social projects and policies.

Abstract:

Production capacity planning with a marginal cost approach and marginal sales proceeds to get the maximum profit at Bengkulu's "SBR" factory. This study aims to find out what the marginal production capacity planning will be produced with the marginal cost approach at Bengkulu's "SBR" plant. This research method is to establish a direct relationship with the tuhu factory "SBR" Bengkulu. The method of analysis is qualitative and quantitative analysis. The variables analyzed in this study are capacity planning and marginal cost. The calculation results are known that the factory knows "SBR" produces marginal production of 120 packs, with the minimum marginal cost of Rp 156.25 occurring in the third quarter of 2012. When compared with production knew that in the fourth quarter of 2012, the factory knew that Bengkulu's "SBR" had a marginal production of 80 packs with a marginal cost of Rp. 2000, so it would be more profitable when marginal production was 120 packs. These results can be concluded that production capacity planning with a marginal cost approach will benefit the factory knowing "SBR" Bengkulu.

This paper extends the use of sample-path analysis to provide relations between frequencies for arbitrary (measurable) sets in function space, rather than just marginal (one-dimensional) frequencies. We define sample-path analogues of the time-stationary and event-stationary (Palm) probability measures for a process with an imbedded point process, and then derive sample-path versions of the Palm transformation and inversion formulas.

Abstract:

In modern economic theory and practice, there is a whole range of problems, where the lack of analytical tools does not allow adequately measuring the expected results. A number of hypotheses are presented; proofs of these hypotheses show that a set of important economic problems (planning of cost production, profit, break-even point by product, pricing for new products and evaluation of effectiveness of inno-vation projects) do not meet an appropriate solution because of the lack of analytical tools. As an alternative, solutions of these problems based on the marginal approach concept are proposed. Distribution of fixed costs between types of products (proposed in accordance with the concept of marginal approach) is inherently a covering of fixed costs by marginal profit and formation on this basis of profit and profitableness both by the types of products and by enterprise as a whole. The concept of the marginal approach was also used to solve the problems of pricing on new products of industrial and technical purpose, which allowed forming the lower and upper limits of prices on an anti-costly basis. Methods for evaluating the effectiveness of innovative projects, which are pre-sented in economic literature and practice from the second half of the 20th century, are reduced to comparing investments with magnitude of profit from sale of an in-novative product during its life cycle. It is proposed to compare investments with the marginal profit received by the enterprise from a new product during its life cycle (of course, taking into account discounting). The results obtained have theoretical value, since they allow new ways to form cost price, profit and profitableness by product types, offer an anti-costly approach to pricing with provision of appropriate tools, as well as evaluation of effectiveness of innovation projects. And a practical significance of these results is to create ap-propriate conditions for a flexible cost management, profits and prices, which is es-pecially important for a rapidly changing market conditions.

Full text

Abstract:

Aim/Purpose: The article is designed to contradict the existing opinion that “transdisciplinarity is a marginal direction of contemporary science.” Background: The difficulties of implementing transdisciplinarity into science and education are connected with the fact that its generally accepted definition, identification characteristics, and methodological features are still missing. In order to eliminate these disadvantages of transdisciplinarity, its prime cause and initial idea had to be detected. Then an attempt was made to analyze correspondence of the existing opinions about transdisciplinarity with the content of its prime cause and initial ideas. Methodology: The bibliometric content analysis of the literature reviews on the subject of transdisciplinary was used in order to determine correspondence of the opinions about transdisciplinarity with the meaning of its prime cause and initial ideas, as well as to generalize these opinions. This method allowed detecting and classifying opinions into 11 groups including 39 stereotypes of transdisciplinarity. For substantiation of transdisciplinary approaches consistency with the approaches of the contemporary science C.F. Gauss random variables normal distribution was used. The “Gauss curve” helped to show the place of transdisciplinary and systems transdisciplinary approaches in the structure of academic and systems approaches. The “Gauss curve” demonstrated the step-by-step broadening of the scientific worldview horizon due to sequential intensification of synthesis, integration, unification, and generalization of the disciplinary knowledge. Contribution: Based on rethinking the results from bibliometric content analysis of the literature reviews, the generalized definition of transdisciplinarity could be formulated, as well as the definition for the transdisciplinary and systems transdisciplinary approaches could be given. It was shown that transdisciplinarity is a natural stage for development of contemporary science and education, and the transdisciplinary approaches were capable to suggest the methods and tools to solve the complex and poorly structured problems of science and society. Findings: Many existing stereotypes of transdisciplinarity do not meet its prime cause and initial ideas. Such stereotypes do not have deep philosophic and theoretical substantiation, as well as not suggesting the transdisciplinary methods and tools. Thus, the authors of such stereotypes often claim them to be transdisciplinary or suggest perceiving them as transdisciplinarity. This circumstance contributed to the fact that many disciplinary scientists, practitioners, and initiators of higher education view transdisciplinarity as a marginal direction of contemporary science. Based on the generalized definition of transdisciplinarity, as well as its prime cause and initial ideas, we managed to show that transdisciplinarity is presented in contemporary science in the form of two different approaches: the transdisciplinary approach and the systems transdisciplinary approaches. The objective of the transdisciplinary approach is ensuring science development at the stage of synthesis and integration of disciplinary knowledge. The objective of the systems transdisciplinary approach is ensuring solving of modern society problems using unification and generalization of disciplinary knowledge. Recommendation for Researchers: The researchers should consider that within the limits of the transdisciplinary approach the disciplinary specialists are managed. Within the limits of the systems transdisciplinary approach the disciplinary knowledge is managed. Thus, the transdisciplinary approach is efficient for organization and research with participation of the scientists of complementary disciplines. An example for such research can be a team of researchers of medical disciplines and complimentary disciplines from chemistry, physics, and engineering. The systems transdisciplinary approach is efficient for organization and performance of research with participation of scientists of non-complementary disciplines, for example, economics, physics, meteorology, chemistry, ecology, geology, and sociology. Future Research: In terms of the main initial idea, transdisciplinarity is formed as a global approach. The global approach should have a traditional institutional form: it should be a science discipline (meta-discipline) and have carriers with the transdisciplinary worldview. Training for such carriers can be organized by the universities within the limits of the systems transdisciplinarity departments and Centers of Systems Transdisciplinary Retraining for Disciplinary Specialists. Thus, it is reasonable to initiate discussion for the idea to reform the disciplinary structure of the universities considering creation of such departments and centers.

Abstract:

The three-dimensional marginal separation of a boundary layer along a line of symmetry is considered. The key equation governing the displacement function is derived, and found to be a nonlinear integral equation in two space variables. This is solved iteratively using a pseudospectral approach, based partly in double Fourier space, and partly in physical space. Qualitatively the results are similar to previously reported two-dimensional results (which are also computed to test the accuracy of the numerical scheme); however quantitatively the three-dimensional results are much different.

Full text

Abstract:

Temporal shaping of time series is the activity of deriving a time series model with a prescribed marginal distribution and some sample path characteristics. Starting with an empirical sample path, one often computes from it an empirical histogram (a step-function density) and empirical autocorrelation function. The corresponding cumulative distribution function is piecewise linear, and so is the inverse distribution function. The so-called inversion method uses the latter to generate the corresponding distribution from a uniform random variable on [0,1), histograms being a special case. This paper shows how to manipulate the inverse histogram and an underlying marginally uniform process, so as to “shape” the model sample paths in an attempt to match the qualitative nature of the empirical sample paths, while maintaining a guaranteed match of the empirical marginal distribution. It proposes a new approach to temporal shaping of time series and identifies a number of operations on a piecewise-linear inverse histogram function, which leave the marginal distribution invariant. For cyclical processes with a prescribed marginal distribution and a prescribed cycle profile, one can also use these transformations to generate sample paths which “conform” to the profile. This approach also improves the ability to approximate the empirical autocorrelation function.

Full text

Abstract:

This paper is concerned with the formation maintenance of a group of autonomous agents under generalized cyclic pursuit (GCP) law. The described pattern for agents under such formation is epicycle-like. For a network of agents to achieve such a formation, marginal stability of the overall network is required. The desired marginal stability of the network relies on each agents’ gain values, and uncertainties in these gains can occur. Previous studies have used fixed gains, we enhance the stability of the gains via a dynamic approach using an integral sliding controller (ISC). An ISC can ensure sliding behavior of the gains throughout the entire response, and it is shown that the gains are robust toward variations and thus make the network keep its marginal stability and its formation.

Full text

Abstract:

The paper gives stochastic assessments of the financial crisis and discusses the Value at Risk European stocks from the point of view of copula based approach. Copula techniques can be based on the connection between rank correlation and certain one–parameter bivariate copulas. This relation allows easy calibration of the parameters. We use more general numerical calibration techniques that are based on maximum likelihood estimation (MLE). Using this approach we want to estimate VaR of the EU stocks portfolio using Monte Carlo simulation. The focus will be on modelling the interdependence between two risk factor returns. We suppose that the risk factor returns have some assumed marginal distributions, which need not be identical, and their dependency is modelled with copulas. We find that standard parametric copula functions (such as Gaussian) are not able to provide a good fit to the data. This is especially true when one or more of the marginal distributions has fat tails. We overcome this problem by fitting a t–copula with different marginal which can approximate any possible shape for the joint density.

Abstract:

In this paper, the reasons for marginal growth in Mashhad were examined. Marginalization in the areas around the city was reviewed and the margin management in the direction of empowerment was evaluated. The main goal is to find solutions for better management of marginalized areas based on empowerment approach. Research method is descriptive-analytic and data are obtained through documentary and field studies (completed questionnaires). In order to test the research hypotheses, statistical analysis of factor analysis, analysis of variance, Spearman correlation coefficient and Mann-Whitney test have been used. The statistical population consists of 922282 people in eight marginal areas of Mashhad that includes 66 marginal neighborhoods. From statistical population, 400 people were selected as samples. To obtain sample size, the Cochran formula has been used with a 95% confidence interval and a standard error of 5%. The research findings show that the best solution for better management of the marginalized areas is the economic empowerment of the marginalized population, which, of course, has been implemented for empowerment. In the field and practical part, 384 randomly selected questionnaires were completed by residents of marginal neighborhoods of Mashhad. Finally, in the analytical section, the information obtained in the above steps was analyzed using the SPSS software program.

Abstract:

This study aims to provide joint modelling of rainfall characteristics in Peninsular Malaysia using two-dimensional copula. Two commonly regarded as important variables in the field of hydrology, namely rainfall severity and duration were derived using the Standard Precipitation Index (SPI) and their univariate marginal distributions are further identified by fitting into several distributions. The paper uses a Bayesian framework to estimate the parameter values in the marginal and copula model. The approximation of the posterior distribution by random sampling has been done by Monte Carlo Markov Chain (MCMC). Next, the authors compared these findings with those based on the classical procedure. The results indicated that the Bayesian approach can be substantially more reliable in parameter estimation for small samples.

Abstract:

In this paper, we estimate the emissions resulting from electric vehicles in Germany. We make use of EMOB, a comprehensive simulation model that provides a forecast and evaluation of the diffusion of alternative fuel vehicles in the next decades. Our method to compute emissions differs from existing ones by a "pivotal marginal" or "hourly marginal" calculation that takes into account the predicted time pattern of EV reloading and can offer a parsimonious alternative to resource intensive micro simulation models. Our approach results in EV emissions of 87 g/km in 2012 and 82 g/km in 2020. These estimates are much higher than those provided by simplified approaches (marginal and average emission) in the short run and get close to marginal emissions after 2035. Co-ordinated charging may reduce the emissions only marginally (usually less than 4 %). Generally, our findings cast doubts on the general claim that electric cars could be fuelled by renewable energy in general, and with fluctuating excess supply of renewables (wind, solar) in particular. This conclusion persists even in the presence of realistic coordination schemes.

Abstract:

Background: Parotid gland is most commonly involved in tumors, comprising about 80% of the salivary gland neoplasms. Majority of parotid tumors are benign in nature, the most common being pleomorphic adenoma. Superficial Parotidectomy is the preferred treatment option, using either anterograde or retrograde approach. The objective of this study was to determine the post-operative facial nerve status and other complications following superficial Parotidectomy by retrograde dissection for benign lesions of parotid gland.Material and Methods: This prospective clinical study included a total of 22 patients who had superficial Parotidectomy by retrograde technique involving marginal mandibular nerve dissection. These patients were studied post-operatively for facial nerve status, Frey’s Syndrome, wound infection and salivary fistula.Results: Out of a total of 22 patients, 54.54% developed temporary facial palsy on ipsilateral angle of mouth and all of them recovered by the end of 3 months post-surgery. Two patients (9.09%) developed salivary gland fistula and both of them healed spontaneously within two weeks. Frey’s Syndrome and wound infection were not seen in any of the patients included in the study. Histopathology of these lesions revealed pleomorphic adenoma (n=20) and Warthin’s tumor (n=2), respectively.Conclusion: The use of marginal mandibular nerve as a landmark for retrograde dissection of facial nerve in superficial Parotidectomy is a reliable method to ensure lower percentage of facial nerve injury and associated complications.

Abstract:

Emotion detection is an important research issue in electroencephalogram (EEG). Signal preprocessing and feature selection are parts of feature engineering, which determines the performance of emotion detection and reduces the training time of the deep learning models. To select the efficient features for emotion detection, we propose a maximum marginal approach on EEG signal preprocessing. The approach selects the least similar segments between two EEG signals as features that can represent the difference between EEG signals caused by emotions. The method defines a signal similarity described as the distance between two EEG signals to find the features. The frequency domain of EEG is calculated by using a wavelet transform that exploits a wavelet to calculate EEG components in a different frequency. We have conducted experiments by using the selected feature from real EEG data recorded from 10 college students. The experimental results show that the proposed approach performs better than other feature selection methods by 17.9% on average in terms of accuracy. The maximum marginal approach-based models achieve better performance than the models without feature selection by 21% on average in terms of accuracy.

Abstract:

AbstractEfficient allocation of water requires knowledge of water's value in both consumptive and nonconsumptive uses. This study estimates the marginal value of water in lake recreational and aesthetic (RA) use. An hedonic price equation (employing the Box-Cox functional form) indicates lake front location, distance to lake, and scenic view are significant RA characteristics of housing. Water front properties command a premium price for the private access they offer. Beyond the water front, the marginal RA price falls rapidly with increasing distance, becoming asymptotic to some minimum. Twenty-two percent of housing price is found to be attributable to the RA component.
