Available in PDF, EPUB and Kindle. Book excerpt: The field of fractional calculus (FC) is more than 300 years old, and it presumably stemmed from a question about a fractional-order derivative raised in communication between L'Hopital and Leibniz in the year 1695. This branch of mathematical analysis is regarded as the generalization of classical calculus, as it deals with the derivative and integral operators of fractional order. The tools of fractional calculus are found to be of great utility in improving the mathematical modeling of many natural phenomena and processes occurring in the areas of engineering, social, natural, and biomedical sciences. Fractional Difference, Differential Equations, and Inclusions: Analysis and Stability is devoted to the existence and stability (Ulam-Hyers-Rassias stability and asymptotic stability) of solutions for several classes of functional fractional difference equations and inclusions. Some equations include delay effects of finite, infinite, or state-dependent nature. Others are subject to impulsive effect which may be fixed or non-instantaneous. The tools used to establish the existence results for the proposed problems include fixed point theorems, densifiability techniques, monotone iterative technique, notions of Ulam stability, attractivity and the measure of non-compactness as well as the measure of weak noncompactness. All the abstract results are illustrated by examples in applied mathematics, engineering, biomedical, and other applied sciences. Introduces notation, definitions, and foundational concepts of fractional q-calculus Presents existence and attractivity results for a class of implicit fractional q-difference equations in Banach and Fréchet spaces Focuses on the study of a class of coupled systems of Hilfer and Hilfer-Hadamard fractional differential equations

Download or read book Using Time Series to Analyze Long Range Fractal Patterns written by Matthijs Koopmans and published by SAGE Publications. This book was released on 2020-09-23 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents methods for describing and analyzing dependency and irregularity in long time series. Irregularity refers to cycles that are similar in appearance, but unlike seasonal patterns more familiar to social scientists, repeated over a time scale that is not fixed. Until now, the application of these methods has mainly involved analysis of dynamical systems outside of the social sciences, but this volume makes it possible for social scientists to explore and document fractal patterns in dynamical social systems.

Download or read book Organizations in the Face of Growing Competition in the Market written by Anna Ujwary-Gil and published by Institute of Economics, Polish Academy of Sciences. This book was released on 2019-01-01 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The essence of the functioning of any organization, whether commercial or non-profit, is to provide value to groups of recipients whose expectations undoubtedly change over time. Various competition mechanisms in the market apply to both business-oriented organizations and organizations operating in the sphere of public utilities. This monograph includes examples of the problems facing contemporary organizations, and at the same time provides evidence, confirmed by research results, that indicates the direction of current changes. The analysis of changes taking place in organizations was carried out in many dimensions. The content layout adopted in the monograph presents four research perspectives, where the subject of the research is the organization; the modern tools used in organization management, the impact of the market economy on organizations, and sectoral or industry aspects of the organization’s functioning. In the first chapter, four studies related to commercial and non-commercial organizations have been collated. Researchers of academic organizations who in order to meet the expectations of students increase their activity in the field of entrepreneurship and their support for the most talented students. Both examples show the need to conduct research, develop knowledge about own activities, and focus on the needs of the environment. Entrepreneurial universities are open to the implementation of joint ventures with entities in their environment, which affect the development of the university, its students, as well as the entities. Entrepreneurship, which is based on the ability to take advantage of market opportunities, also creates opportunities for developing the ability to flexibly shape and adapt programs, methods and operating principles to the growing expectations of their environment. The ability to develop your potential as well as the potential of your students plays a crucial role. In the pursuit of excellence, a strong focus should be placed on talented students and the development of all possible forms of support that could determine an output of graduates with particularly high development potential. In the research presented in this monograph, the authors compare the activity of universities in the USA, the Netherlands, and Poland in the area of talent development. The comparative analysis becomes a valuable source of indicating imperfections, but also examples of potential forms of positive activity in this area. Equally important in this part of the monograph is the research on the learning organization. Through a bibliometric analysis, the author identified the fields of research on the learning organization. In addition to research areas related to various dimensions, primarily human, cultural and managerial, the types of organizations in which such research is most often conducted have been indicated. They also include the organizations of the two sectors presented: education and healthcare. The same part of the monograph also presents the results of research in the hotel sector, where the main research problem was the creation of customer value, taking into account the conditions stimulating the dynamics of the business models of hotel enterprises. Referring to business models was considered important because of the significance of decision-making patterns that help to build a competitive advantage and achieve market success by creating value for customers. The concept of creating value for customers is currently treated in cross-sectoral or industry categories and is a universal approach to managing organizations. The second chapter of the monograph presents research on the modern tools used in organization management. Concepts such as work–life balance, shaping the innovation process within the framework of decisions taken in the process, marketing communication, or the use of gamification in research and development, are examples of a wide range of relationships between today’s organization and its surroundings. Finding employees, and retaining them, is also a growing challenge in developing countries, where labor supply is steadily decreasing. The expectations of employees are increasing, especially in relation to respecting the personal, non-professional side of life. Thus, it should be recognized that research on work–life balance is a developing space for organization and management researchers. Modeling the innovation process in an organization is another research trend that is important today, especially in terms of developing competitiveness. Decision-making is one of the key components of the innovation process. This aspect, in qualitative terms, was presented in the next study in the second part of the monograph. Similarly, marketing communication is invariably an important area of research in organizations, which has evolved due to rapidly developing information technologies and, at the same time, the changing preferences of users of these technologies. The last study in this second part of the monograph relates to innovation and the use of computer games. The tools of gamification are used to shape the attitudes of individual energy consumers. The observations presented show that it is worth making attempts to use unconventional methods and tools, in this case, to develop customer knowledge and strengthen the behaviors desired in the energy market. The third chapter of the monograph is devoted to the financial aspects of the functioning of commercial and non-profit organizations in a market economy. Increasing the efficiency of public entities, specifically conditioned in economic policies and dependent on political decisions, has been the subject of numerous studies. The research study presented in the monograph refers to the relationship between financial strategies and profit management in public industrial companies listed on the Warsaw Stock Exchange. It is worth noting that no research in this field has been conducted to date in the context of the Polish capital market. The next study refers to the French market. Its purpose was to evaluate and test long-term memory in the French stock exchanges. Research results contribute significantly to explaining the lack of consensus regarding long memory in stock returns. The research covers a significant, 25-year period of operation of the Euronext platform during which 6634 observations were provided. The conclusions of the study may be particularly important for regulators and risk managers. Another study presents the results of bankruptcy risk tests for Polish and Czech logistics companies using a comprehensive classification approach. As a result of the research, a tool for risk assessment and forecasting was developed, enabling the early prediction of bankruptcy of enterprises. At the end of the third chapter of the monograph, the results of health expenditure analysis based on information provided by the Health Account System are presented. Particular attention has been focused on the programming sources of financing healthcare in new European Union countries. Socio-technical and environmental aspects of the organization are the subject of interest of researchers presenting the results of their research in the fourth chapter of the monograph. The problems of economic migration and working conditions have been the subject of interest for many years in the strongly developing trend of labor market research. The research results contained in the study relate primarily to the issues of occupational safety of Ukrainians employed in Poland. These issues are gaining importance, especially when the number of people migrating from Ukraine to Poland in search of work has been growing for several years. In the face of such a large scale of Ukrainian immigrants employed in Polish enterprises, there is still a lack of regulations protecting or securing the interests of employees and employers. The next research presentation highlights the problems of the “circular economy,” which, according to the author, is developing too slowly in Poland. The research is valuable for systematizing the idea of a circular economy based on the theoretical and practical aspects of this phenomenon. The results of the analysis are also of practical importance for the process of modeling and implementing this idea in Poland. Further, the innovation paradigm of economic health and the prosperity of society is the subject of the research carried out, based on a review of the health economy considering innovation and its impact on population growth and prosperity in the world. The research particularly highlights the consequences of socio-demographic, environmental and business changes in the field of consumer goods. The socio-technical, as well as the environmental, aspects of the organization are also included in the last study presented. The purpose of this study was to identify the attitudes of IT employees in the Polish ITC sector towards remote work. Since the effective and efficient collaboration of distributed employees performing remote work has become even more necessary for the success of projects, numerous research works are being conducted focusing on the consequences of remote work. The presented research results are an important contribution to the discussion of researchers and management practitioners. By publishing this monograph, which covers a wide spectrum of research problems in contemporary commercial and non-profit organizations, the editors and authors presenting the results of their research express a hope that they are contributing to the widespread dissemination and enrichment of knowledge and, consequently, socio-economic development.

Download or read book Stochasticity Nonlinearity and Forecasting of Streamflow Processes written by Wen Wang and published by IOS Press. This book was released on 2006 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Streamflow forecasting is of great importance to water resources management and flood defense. On the other hand, a better understanding of the streamflow process is fundamental for improving the skill of streamflow forecasting. The methods for forecasting streamflows may fall into two general classes: process-driven methods and data-driven methods. Equivalently, methods for understanding streamflow processes may also be broken into two categories: physically-based methods and mathematically-based methods. This thesis focuses on using mathematically-based methods to analyze stochasticity and nonlinearity of streamflow processes based on univariate historic streamflow records, and presents data-driven models that are also mainly based on univariate streamflow time series. Six streamflow processes of five rivers in different geological regions are investigated for stochasticity and nonlinearity at several characteristic timescales.

Download or read book Monetary Policy and Issues written by Lauren C. Williams and published by Nova Publishers. This book was released on 2006 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1970's, many countries were plagued by persistently high inflation rates, which were thought to cause a significant loss in economic efficiency. Since persistent inflation is considered to be ultimately the result of monetary policy, many countries in the 1990s sought institutional reforms to their central banks to prevent a return to the 1970s experience. A popular reform was to move from giving central banks multiple policy goals to a single mandate of price stability. The single mandate was accompanied by the introduction of an inflation target, in which central banks aim to keep inflation within a pre-defined numerical range. The logic behind these reforms was a belief among proponents that it would remove the political temptation to 'pump up' the economy in the short run at the expense of long-run price stability, and a belief that 'fine tuning' monetary policy in response to every change in economic conditions, was of little value. This book develops quantitative measurements to analyse the success of inflation targeting abroad by comparing both the performance of targeters to non-targeters and the performance of countries before and after targeting was adopted.

Download or read book Causal Inference in Econometrics written by Van-Nam Huynh and published by Springer. This book was released on 2015-12-28 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the analysis of causal inference which is one of the most difficult tasks in data analysis: when two phenomena are observed to be related, it is often difficult to decide whether one of them causally influences the other one, or whether these two phenomena have a common cause. This analysis is the main focus of this volume. To get a good understanding of the causal inference, it is important to have models of economic phenomena which are as accurate as possible. Because of this need, this volume also contains papers that use non-traditional economic models, such as fuzzy models and models obtained by using neural networks and data mining techniques. It also contains papers that apply different econometric models to analyze real-life economic dependencies.

Download or read book Time Series Techniques for Economists written by Terence C. Mills and published by Cambridge University Press. This book was released on 1990 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of time series techniques in economics has become increasingly important, both for forecasting purposes and in the empirical analysis of time series in general. In this book, Terence Mills not only brings together recent research at the frontiers of the subject, but also analyses the areas of most importance to applied economics. It is an up-to-date text which extends the basic techniques of analysis to cover the development of methods that can be used to analyse a wide range of economic problems. The book analyses three basic areas of time series analysis: univariate models, multivariate models, and non-linear models. In each case the basic theory is outlined and then extended to cover recent developments. Particular emphasis is placed on applications of the theory to important areas of applied economics and on the computer software and programs needed to implement the techniques. This book clearly distinguishes itself from its competitors by emphasising the techniques of time series modelling rather than technical aspects such as estimation, and by the breadth of the models considered. It features many detailed real-world examples using a wide range of actual time series. It will be useful to econometricians and specialists in forecasting and finance and accessible to most practitioners in economics and the allied professions.
