An Essay on China’s Development After the Demographic Golden Age - Original PDF
نویسندگان: خلاصه: Su Shi, a well-known ci poet of the Song Dynasty, wrote a seven-character quatrain: “It is a range viewed in face and peaks viewed from the side, assuming different shapes viewed from far and wide. Of Mountain Lu we cannot make out the true face, for we are lost in the heart of the very place”. The poem not only depicts the picturesque scenery of Mountain Lu and contains the dialectical idea that those closely involved in something cannot see it clearly, but also provides people with ways and means to observe things, giving the poem an enduring appeal. When we look at the past four million years of human evolution, the trajectory of humanity before they reach the pinnacles of achievements in economic, technological, cultural, and social dimensions today, we may find out there are three distinct eras. As is known to many, an economic era is not defined by what is produced, but by how and what kind of tools are used for production. As the production tools typical of an era vary, so does the capital an economy depends on for growth. We may roughly divide the economic development of humanity into three eras, characterized by hand tools and natural capital, by machine tools and production capital, and by intellectual tools and human capital, respectively. In the era of hand tools, agrarian and prior forms of society—which span from primitive, slave to feudal societies—relied mainly on natural capital. Natural capital provides natural means of living and production, and the multiplication of popula- tion is mainly reflected in the size of the workforce. Therefore, ancient and medieval civilizations appeared mostly in places with fertile land, abundant precipitation, mild climate, convenient land and water transportation, a dense population and large labor force. Cases in point are the five cradles of civilizations, namely, ancient Mesopotamia along the Tigris and Euphrates, ancient Egypt along the Nile Valley, ancient India along the Ganges River, ancient China along the Yellow River, and ancient Greece. The prosperity of the Seljuk Empire, the Russian Empire, and the French Empire in the Middle Ages could also be attributed to their superiority in natural capital and population
Helix Network Theory The Dynamic Structure and Evolution of Economy and Society Interdisciplinary Integrated Economics Creating a Brand New “Micro-Meso-Macro” Paradigm - Original PDF
نویسندگان: خلاصه: Foreword by Gong-Meng Chen I first met and started working with Gan Runyuan, the author of the book, around April and May of 2002. Back then, I had just established the China Accounting and Finance Research Centre at Hong Kong Polytechnic University in Shenzhen. Because the research centre was not long established, it was necessary to introduce various talents. Gan Runyuan was one of the first groups of personnel recruited into the research centre. By 2003, with the active support of Cheng Si-Wei, I and my colleagues had founded the China Venture Capital Research Institute. During that period of time, Gan Runyuan worked as my assistant and participated in many tasks at the China Accounting and Finance Research Centre and China Venture Capital Research Institute. He was easy-going, serious in working, and I was always impressed. Later, Gan Runyuan left Shenzhen to Shanghai. However, he still kept in touch with me and participated in several forums organised by the China Venture Capital Research Institute. At the end of March this year, Gan visited Shenzhen. I learned that he had written an economics monograph, Helix Network Theory, and he invited me to write a preface to this book. He said that this is the ten-year brainchild of his toil, blood, and sweat. I did not expect him after leaving Shenzhen for more than ten years, not only reading that many books on economics and sociology but also spending quite a few years writing an econo
The Chinese Path Toward a Leaner Government - Original PDF
نویسندگان: خلاصه: Building a leaner government ( Jian Zheng Fang Quan , or “streamlining admin- istration and delegating powers” in the official translated documents) is essential in China’s transition from a planned economy to a market economy and in an effort to improve the country’s socialist market economy. People of our generation have all had some experiences with the planned economy. It was a time when the government managed everything from production to consump- tion. In other words, the government assumed the role of both the producer and distributor of goods. Little was outside the government administration. It set quotas that matched its plans and organized supplies according to the quotas. No one in China at that time had ever heard about the term Jian Zheng Fang Quan or stream- lining administration and delegating powers. In fact, it was impossible to streamline the government then because everything was controlled by the government, every decision had to come from the higher authorities, and all kinds of stuff were placed under the quota system. When a government assigned each of its staff with a particular task to either manage or supervise economic activities, how could it be streamlined? Power devolution was even more beyond imagination. The planned economy was based on the concentration of power. If power was delegated, how could the economy and people’s daily life go as the government had planned for them? Indeed, there were times when the Chinese government was concerned about the low efficiency and poor performance of the planned economy that too much concentration of power had entailed. However, there were no better ways. China had quite a few lessons learnt in a hard way. Trials to cut government power or remove some quota all ended up in market disorder. Shifting back to old practice only stifled the economy. Such policy flip-flops occurred time after time during the period of the planned economy. It was a doomed cycle that no one was able to brea
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
The Relational Governance of Artificial Intelligence Forms and Interactions - Original PDF
نویسندگان: خلاصه: he book “The Relational Governance of Artificial Intelligence—Forms and Inter- actions” by Sabine Wiesmüller deals both with the theoretical prerequisites and prac- tical possibilities of the governance of “Artificial Intelligence” (AI) in the interplay of social, entrepreneurial, and ethical decision-making logics. In particular, Sabine Wiesmüller’s book aims to contribute to the discussion of a theme that all societies are confronted with today and for which solutions are being sought, namely the complex interactions and network effects of the technological, economic and social aspects of AI. The book focuses on a genuinely interdisciplinary analysis: The overlap and rela- tionalisation between economic, system-theoretical, and ethical language games. Only through such a relationalisation—and this is one of the basic assumptions of the author—can the challenges of the rapidly developing technical and economic possi- bilities, risks, and challenges of artificial intelligence in the economy and society be understood and productively dealt with. The aim of the analysis is therefore twofold: On the one hand, it provides a theo- retical literature reconstruction of the polyvalent forms of governance of AI. On the other hand, it also addresses the practical possibilities for an intersectoral imple- mentation of relational governance of AI. The latter means that the governance of AI must enable and promote the cooperation of the multiple stakeholders involved, especially their interests, resources and decision-making logics. It is therefore about the relational governance of economic and social transactions that relationalise tech- nical logic, economic value creation and ethical demands such as self-interest, trust, integrity and stakeholder legitimacy. In this way, the adaptive approach to uncertainty and process dynamics becomes possibl
Current Issues in Public Utilities and Public Policy Empirical Studies Focusing on Japan - Original PDF
نویسندگان: خلاصه: Public utility industries are basic to both consumers and firms for main- taining daily life and economic activities. Relevant, practical information based on careful empirical study is necessary to create prudent policy for public utility indus- tries. This chapter summarizes three points: the aim of this book, the characteristics of public industries, and the topic of each chapter. The purpose here is to deepen the general understanding of public utility industries, which, compared with general industries, have distinguishing characteristics such as (i) the necessity for huge infras- tructure networks, (ii) the provision of essential services, (iii) the difficulty of storing services and a peak/off-peak imbalance, (iv) the necessity for a balance of publicness and marketability, (v) the existence of externalities, and (vi) the constraints imposed by public regulation
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
Modern Cryptography Volume 2 A Classical Introduction to Informational and Mathematical Principle - Original PDF
نویسندگان: خلاصه: Preface For integer factorization and discrete logarithm calculation, P.W.Shor published an effective quantum calculation in SIAM Journal on Computing in 1997, which is called the Shor algorithm in academic circles. Classical public key cryptosystems such as RSA, ECC and so on could not resist the attack of the Shor algorithm, so the major security risks of public key cryptosystems are completely exposed to the Shor algorithm and quantum computer. In the past 20 years, the rise and development of post-quantum cryptography have close relation with the lattice cryptosystems. The academic community believes that the hard problems on lattice, such as the shortest vector problem (SVP), the continuous shortest vector problem (SIVP) and the determination of the shortest vector problem (GapSVP) can resist quantum computing effectively, so the public key cryptosystems based on the hard problems on lattice become the core theory and technology of the post-quantum cryptography. At present, there are six kinds of published post-quantum cryptosystems: 1. Ajtai-Dwork cryptosystem (1997). Ajtai constructed a collision-resistant Hash function by the circulant matrix and ideal matrix, and converted the collision point into the shortest vector problem on q-ary integer lattice. Ajtai first proposed the concept of random lattice (Gauss lattice) in 1996, and established the famous reduction principle ‘from the worst case to the average case’. The security of Ajtai-Dwork cryptosystem could be fully proved by this reduction principle. 2. GGH/HNF cryptosystem (1997). In 1997, Goldereich, Goldwasser and Halevi constructed a public key cryptosystem based on the closest vector problem on the q-ary integer lattice, which was further improved by Micciancio using the Hermite normal basis in 2005. The idea of Micciancio is very simple. Since the HNF basis of any lattice can be easily computed from its generated matrix, the GGH cryptosystem uses the HNF basis as the public key directly. 3. NTRU cryptosystem (1998). Number Theory Research Unit (NTRU) is a quantum-resistant computing public key cryptosystem developed by J. Hoffstein, J. Pipher and J. H. Silverman in Brown University in 1998, which has become the most attractive post-quantum cryptosystem due to its simple algorithm, fas

Discrete Element Modelling of Particulate Media by Chuan-Yu Wu - Original PDF
نویسندگان: خلاصه: In numerical simulations of dense two-phase flow involving particulate materials the Discrete Element Method (DEM) has proved particularly effective in capturing the complex hydrodynamics of the solid phase. 1 DEM-based granular solid dynamics, including collisions and persistent contact with elaborate force-displacement laws, friction and cohesion have shown to be superior to traditional fluid-like, continuum approaches, which typically require coarse approximations and the introduction of artificial variables like solids pressure and viscosity. However, computational limitations of DEM models do not allow adding also the burden of flow simulations resolved at the level of particle-particle interstices, so that typically an averaged scale approach, with computational cell sizes of the order of a few particle diameters, is used. 2 .3 As a consequence, formulations of the drag force acting on individual particles are required to close the set of equations to solve for the solid and fluid phases. While many drag force models for monodisperse systems have been proposed in the literature, as discussed below, expressions for such force on a particle in a multi-particle system is currently the subject of extensive research workآیا 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.
