Digital Transformation of the Financial Industry Approaches and Applications - Original PDF
نویسندگان: خلاصه: Preface This book is aimed to be a collection of state-of-the-art research findings in digital transformations across the financial industry from the Central and East European markets. Digitalization is fundamentally changing financial services in the last few decades and tends to reshape the landscape of financial industry in an unprecedented manner. This book seeks to extend the concurrent body of knowledge on digital transformation in the financial industry by encompassing significant conceptual contributions, innovations in methods and techniques and by delineating the main applications of digital transformation in the CEE region. Although the books elaborating digital transformation in finance can be found in the market, these books dominantly focus on developed market. The aim of this book is to progress one-step forward—to focus on practice in developing and transitional/post- transitional countries. When any technology disrupts an industry, trailblazers are usually from the highly developed countries. Diffusion of tech-related disruption is, however, only rarely linear and uninterrupted. Thusly, we were highly motivated to collect the evidence on the development of fintech from the CEE countries. This book can serve to all important fintech stakeholders—students, academic community (with both technical and social science background), and practitioners (decision-makers and policy holders in various organizations of the financial sys- tems). As for the students, typical users are master or doctoral level of education with major subjects covering business, finance, accounting, economics, management science, and other fields in social science and/or engineering. As for the academic community, the book might be interesting for lecturers and scholars from CEE countries. Finally, the book is aimed at practitioners—economic analysts, informa- tion technology developers and information system experts, small investors, insti- tutional investors, as well as regulators of the financial system and national finance
Urban Infrastructure Globalization / Slowbalization - Original PDF
نویسندگان: خلاصه: The book addresses the issue of urban infrastructures within globalization. Slowbal- ization is then introduced rather than deglobalization to indicate important variables that could stand in the way of a prevailing reading key in the book. Wiig et al (2022) argue that starting from a volume (Graham, Marvin, 2001 ) the study of infrastructures has been brought to the center of urban studies and has inspired the infrastructural turn within urban sciences. Infrastructures, and urban ones in particular, precisely because of their differentiation, specialisms, formulas and organizational models that underlie their assembly, governance and management have always appeared residual compared to other themes such as the city, urbaniza- tion, the form urban, competitive advantage, applied globalization; or on another more technical side, specialisms such as engineering or other technical disciplines called upon to assemble and update the various infrastructures in various ways. Moss (2020) on Berlin, which tells the story of that city (1920–2020) through infrastructures, removing them from invisibility, may be singular, but it is not. Putting them at the center offers new ideas and angles both from the point of view of economics, finance, assembly technique and above all the spatiality of the city within the different forms of globalization. Today, urban infrastructures are also a fundamental part of the economy and finance and follow their evolution and trajectory. They assume particular impor- tance starting from the conjugation with the term globalization; we have seen a rapid transformation of the interconnected infrastructure precisely with the growth of glob- alization and the global city. The analysis focused more on what has been called the western global city and the context of the brownfield infrastructure
The Colombian Economy and Its Regional Structural Challenges A Linkages Approach - Original PDF
نویسندگان: خلاصه: Preface I have been teaching a Ph.D. course on “Applied General Equilibrium Models” at the University of São Paulo, Department of Economics, since 1999. Over the last editions of the course, the material was built around specific countries or regions, selected to be the object of modeling practices undertaken by the students. This praxis turned out to be very rewarding for the students since they were motivated to apply different techniques to study concrete problems in a common economic system. Throughout this process, they had the opportunity to collaborate among themselves and interact with scholars from the study regions, often generating scholarly publications. We had already worked with countries such as Brazil, Chile, Greece, and Paraguay, and with different regional contexts, especially within Brazil. Colombia had always been a top candidate to receive our attention. Our previous engagement with colleagues from the Centro de Estudios Económicos Regionales (CEER), a research center specialized in Regional and Urban Economics at the Banco de la República— the Colombian Central Bank—provided a unique opportunity to develop a special edition of the course on the country. During a visit to Cartagena in 2019, Jaime Bonet and I finally agreed to use Colombia as the case study in the forthcoming edition of the course. We designed the Colombian edition in innovative and challenging ways, raising the bar for the expected outcomes, including a workshop to be hosted in Cartagena in 20201 and the publication of a volume including the contributions by different authors forming a cohesive unit. We built the activities upon solid co

نویسندگان: خلاصه: Price movements in the energy market are crucial because energy plays a vital role in the world’s economies and human life. The high volatility in energy prices since the 1990s is due to several historical developments, including the deregulation of energy markets, the Asian financial crisis in 1997, and the 2008 global financial crisis (Lien et al., 2016; Lang & Auer, 2019) have increased the need for an appro- priate protection strategy. Hedging by using futures contracts makes the problem of “finding an appropriate hedge ratio” vital. In calculating the optimal hedge ratio (OHR), estimations are mostly based on the average (expected) relationship between spot and futures prices. This approach ignores the tail distribution of the variables (Lien et al., 2016; Shrestha et al., 2018). However, the widely documented non- normal distribution of financial variables makes considering the quantiles of the variables essential. To fill this gap, we used the recently developed quantile-on- quantile (Q-Q) (Sim & Zhou, 2015) approach to estimate the minimum-variance (MV) hedge ratio for crude oil, natural gas, and gasoline markets. Besides, to have a better understanding of the relationship between these variables, we examined long-run and causal relationships by using methods that consider the distribution of the variables.
Sustainable Development Disciplines for Society Breaking Down the 5Ps—People, Planet, Prosperity, Peace, and Partnerships - Original PDF
نویسندگان: خلاصه: Introduction This multidisciplinary book provides 14 problem-solving lectures on the sustainable development of people, peace, planet, and prosperity—four of the five keywords for the Sustainable Development Goals (SDGs), 4 namely people, planet, prosperity, peace, and partnerships (5Ps). According to the Resolution adopted by the General Assembly of the United Nations (2015, p. 2), the SDGs are intended to promote the following actions in these five areas: (1) For people: end poverty and hunger in all their forms and dimensions, as well as ensure that all human beings can fulfill their potential with dignity and equality and in a healthy environment. (2) For planet: protect it from degradation, including through sustainable consumption and production, by sustainably managing natural resources and taking urgent action on climate change, so that it can support the needs of the present and future generations. (3) For prosperity: ensure that all human beings enjoy prosperous and fulfilling lives and that economic, social, and technological progress occurs in harmony with nature. (4) For peace: foster peaceful and inclusive societies that are free from fear and violence. (5) For partnerships: mobilize the means required to implement this agenda through a revitalized Global Partnership for Sustainable Development based on a spirit of strengthened global solidarity, focusing, in partic- ular, on the needs of the poorest and most vulnerable and with the participation of all countries, all stakeholders, and all people

Global Cooperation and G20 Role of Finance Track - Original PDF
نویسندگان: خلاصه: The realisation that emerging economies were becoming systematically important dawned on the major advanced economies with the Asian and Russian financial crises of the late 1990s, and hence, the necessity was felt for a larger forum than the G7 encompassing the emerging economies. The Group of Twenty Countries (G20) was launched as a forum of the finance ministers and Central Bank governors primarily to address the challenges to international financial stability that had begun in Asia in 1997. The need was felt for a “permanent forum” for informal dialogue between developing and developed countries in the G20. The need for the inclusion of major emerging economies in discussions on the international financial system was underlined by the global financial crisis of 2008. A platform was created where leaders of systemically important countries resolved to coordinate macroeconomic policies to counteract the global financial crisis. In turn, they analysed the deeper, underlying causes of the financial crisis. This chapter introduces and motivates the book and discusses the rationale behind the formation of the G20. It discusses the background of the G20, the role of G7 and G8, and discusses the organisation of the book in the chapters that follow
HCI International 2022 – Late Breaking Posters - Original PDF
نویسندگان: خلاصه: 4 P. Asghari et al. 1 Introduction Eye tracking (ET) is frequently used, for example, in behavioral research and human-computer interaction. Eye movement patterns can reveal detailed infor- mation about the user’s cognitive processes, their attention level, or decision- making processes [3,12]. Applications and research based on ET require reliable and robust data [9]. Traditionally, this requires dedicated hardware with high- resolution cameras and infrared illumination to detect corneal reflections [7]. However, dedicated hardware is expensive and thus limits the pervasive use in real-world applications. This situation may change since, propelled by recent advances in deep learning, appearance-based gaze estimation methods that deliver promising results based on low-cost consumer-grade camera inputs start to emerge [2,10,11,21]. These approaches learn to estimate gazes from a video stream based on large-scale data sets and provide 3D gaze vectors or correspond- ing 2D gaze locations on a screen. Furthermore, they do not require any specific external devices and can be used with standalone computers, laptop built-in webcams, or mobile device consumer-grade cameras. This opens up the possi- bility of developing affordable automated intelligent ET solutions for research, commerce, and the general public. On the way to realize this ambition, webcam ET (wcET) has to address several challenges including gaze estimation accu- racy, gaze estimator prediction time, and that gaze estimation quality can be affected by user movements [11]. This paper aims to contribute to the first step toward utilizing wcET as a low-cost pervasive technology by validating the data quality of a state-of-the-art wcET approach in comparison to the performance of an established, commercially available dedicated eye tracking (dhET) system. Accordingly, we address the following research question in our work: How does the gaze estimates of wcET differ from dhET in practical settings regarding accu- racy, precision, and sampling rate? We will further discuss how the limitations of the data quality may affect the performance of wcET applications

نویسندگان: خلاصه: ID-Based Self-encryption via Hyperledger Fabric Based Smart Contract Ilya Grishkov1, Roland Kromes1(B), Thanassis Giannetsos2, and Kaitai Liang1 1 Cyber Security Group, Delft University of Technology, Delft, The Netherlands I.Grishkov-1@student.tudelft.nl, {R.G.Kromes,Kaitai.Liang}@tudelft.nl 2 Ubitech Ltd., Digital Security and Trusted Computing Group, Athens, Greece agiannetsos@ubitech.eu Abstract. This paper offers a prototype of a Hyperledger Fabric-IPFS based network architecture including a smart contract based encryp- tion scheme that meant to improve the security of user’s data that is being uploaded to the distributed ledger. A new extension to the self- encryption scheme was deployed by integrating data owner’s identity into the encryption process. Such integration allows to permanently pre- serve ownership of the original file and link it to the person/entity who originally uploaded it. Moreover, self-encryption provides strong security guarantees that decryption of a file is computationally not feasible under the condition that the encrypted file and the key are safely stored. Keywords: Blockchain · IPFS · Self-Encryption · Security · Hyperledger Fabric 1 Introduction The modern world is increasingly adopting blockchain technology. The first major market adoption of blockchain happened in 2009 when Bitcoin was introduced [12]. Interest in blockchain solutions grew over the years and lead to the invention of Ethereum - Bitcoin peer but with support for smart contracts which are digital codes enabling the description of complete business logic [1]. The introduction of smart contracts leads to further development in the field of blockchain and cre- ated demand for more industry-friendly solutions that allow to identify users of the system (Know-Your-Customer, Anti-Money-Laundering). Hyperledger Fab- ric was then introduced as a highly modular permissioned blockchain that allows great customization to suit particular industrial needs [3]. Given its customizabil- ity and modularity, Hyperledger Fabric (HLF) is a perfect platform for extending it with various trust and privacy preservation solutionsآیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
