The Economics of Optimal Growth Pathways Evaluating the Health of the Planet’s Natural and Ecological Resources - Original PDF
نویسندگان: خلاصه: If you are a natural resource manager of, say, four acres of cropland or two hectares of forest stand, how would you manage it over your planning time horizon? This is the first and most fundamental question you have to answer in your brain before you get your hands and feet down and dirty. Any reasonable answer would encompass many future time periods, that is, beyond the single present time period, as well as a possibility of convert- ing it to another land use at one future period or even selling it (Ricardo 1817; von Thunen 1826; Faustmann 1849). The economics of optimal growth pathways, the book in your hands or on your kindle presently, is written to provide a rational answer to this question faced by the respective natural resource manager. The scope of this book is, however, far greater than cropland farming or forest manage- ment. This book starts with “four acres” of cropland in Chap. 2, continues to the nation’s economy from Chap. 8 onwards, and ends big with the planet’s atmosphere and the global economy from Chap. 11. The purview of this book falls on the planet’s resources and the economic systems built upon it.
Fundamentals_of_Computer_Graphics - Original PDF
نویسندگان: خلاصه: Preface This edition of Fundamentals of Computer Graphics includes substantial rewrites of the material on shading, light reflection, and path tracing, as well as many corrections throughout. This book now provides a better introduction to the tech- niques that go by the names of physics-based materials and physics-based ren- dering and are becoming predominant in actual practice. This material is now better integrated, and we think this book maps well to the way many instructors are organizing graphics courses at present. The organization of this book remains substantially similar to the fourth edi- tion. As we have revised this book over the years, we have endeavored to retain the informal, intuitive style of presentation that characterizes the earlier editions, while at the same time improving consistency, precision, and completeness. We hope the reader will find the result is an appealing platform for a variety of courses in computer graphics. About the Cover The cover image is from Tiger in the Water by J. W. Baker (brushed and air- brushed acrylic on canvas, 16” by 20”, www.jwbart.com). The subject of a tiger is a reference to a wonderful talk given by Alain Fournier (1943–2000) at a workshop at Cornell University in 1998. His talk was an evoca- tive verbal description of the movements of a tiger. He summarized his point: Even though modelling and rendering in computer graphics have been improved tremendously in the past 35 years, we are still not at the point where we can model automatically a tiger swimming in the river in all its glorious details. By automatically I mean in a way that does not need careful manual tweaking by an artist/expert. The bad news is that we have still a long way to go. The good news is that we have still a long way to go
The Ethics of Bribery Theoretical and Empirical Studies - Original PDF
نویسندگان: خلاصه: he present study is part of a much larger study that examines the ethics of bribery and tax evasion. The bribery studies consist (so far) of two books (McGee & Benk, 2023a; McGee & Benk, 2023y) and many articles and book chapters. Summaries of 28 studies (McGee, 2023a), 24 studies (McGee, 2023b), 44 studies (McGee, 2022a), and 80+ studies (McGee, 2022b) are also available. The tax evasion studies started in 1994 (McGee, 1994) and picked up speed in 1998 when the first book in the tax evasion series was published (McGee, 1998). The second book in the series was published in 2012 (McGee, 2012a). Two more books were recently added to the tax evasion collection (McGee & Shopovski, 2023a, b). Many articles and book chapters on the ethics of tax evasion have been published over the years. Summaries of many of them are available. There are sum- maries of 49 studies that used a survey template that usually consisted of 18 state- ments starting with the phrase, “Tax evasion is ethical if ...” (McGee, 2012b). Another study summarized 23 studies that used World Values Survey data (McGee, 2012c). Other studies summarize 3 studies (McGee, 2012d), 21 studies (McGee, 2022c), 35 studies (McGee, 2022d), 60+ surveys (McGee, 2022e), 70+ theoretical and empirical studies (McGee, 2022f), 100+ studies (McGee, 2022g), 80+ studies (McGee, 2022h), 34+ studies (McGee, 2022i), and 44+ studies (McGee, 2022j). Part II of the book addresses attitudes toward bribery from different religious perspectives. The first chapter in this section provides a comparative study of reli- gious attitudes toward bribery (McGee et al., 2023a). There are also chapters that report on attitudes of Christians (McGee et al., 2023b), Muslims (McGee et al.
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
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
Rethinking Management and Economics in the New 20’s The 2022 Centre of Applied Research in Management and Economics (CARME) Conference - Original PDF
نویسندگان: خلاصه: This study was developed using scientometrics tools and the purpose was to identify and evaluate the scientific production in hedge accounting until the year 2021. The investigation describes a quantitative overview of published studies focusing on hedge accounting and provides information on the performance of arti- cles, journals, and authors of the collected sample. This article contributes to the literature by exploring through maps and graphs the expressions and words most used by the authors in order to identify the main fields of investigation and try to observe the changes in the guidelines of the studies over the years. Through the results of the sample analysis, it is possible to suggest the incorporation and development of new trends in the fields of investigations related to hedge accounting over the years. The results obtained in the regression model corroborate the idea of evolution in the theme of this research field. Finally, the results showed that the annual scientific productions published showed non-constant growth. A study published in 1995, prior to the publication of IAS 39, is the most influential of the sample in terms of total citations and citations per year, corroborating the idea that despite the emergence of new directions in research, main investigations are used as a matrix in the search field
Seasonal Adjustment Without Revisions A Real-Time Approach - Original PDF
نویسندگان: خلاصه: Preface In the 1980s, the first author was asked for information about profit prospects of a number of companies, in order to predict the change of their prices on the stock market. He looked up annual reports and recent interim results of these companies and noted that interim results consisted largely of a comparison of recent quarterly results to those of the same quarter of the preceding year. Moreover, stock prices reacted instantly to the outcomes of these comparisons. He was struck by the fact that these outcomes were frequently predictable: If there had been an up or down in the preceding year’s quarterly result, this would affect the comparison to the recent quarter. If last year’s ups or downs had been large, such as a profit on the sale of a construc- tion, or a depreciation of goodwill, these would be referred to in the comparison of the present quarterly report and would not come as a surprise and have little or no impact on stock prices. But if the market had become used to rising quarterly profits of Company X to the tune of say 1% over the preceding year, then an increment of ‘only’ 0.5% in the recent quarter would have a negative impact on the stock prices. Yet, this slight reduction in the profit’s increment may have its cause not in the present quarter, but in the preceding year or in the preceding few quarters. But then it is predictable
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
50 Literacy Strategies Step by Step Fourth Edition - Original PDF
نویسندگان: خلاصه: Young children write “All About . . .” books on familiar topics (Tompkins, 2012). They put together a booklet with four or five pages, write a sentence or two on each page, and add illustrations to elaborate the information presented in the text. Stu- dents read the book to the teacher, who helps them elaborate ideas and correct mechani- cal errors before they share from the author’s chair (see p. 10). As they gain experience writing books with one or two sentences per page, students can expand and elaborate the information they share on each page, gradually increasing the length to a paragraph
Assistive Technologies and Environmental Interventions in Healthcare - Original PDF
نویسندگان: خلاصه: The changes we have all seen in technology and corre spondingly with assistive technology in the past 10 years are mind‐boggling. Futurist and inventor Ray Kurzweil (2000) stated early in the twenty‐first century that com puters are 100 million times more powerful than they were 50 years ago. The exponential growth of computer capacity that Kurzweil and others predicted in the late 1990s continues to advance and has the potential for improving all aspects of life (Diamandis and Kotler 2014). These exponential changes in technology make it hard to keep up with the latest innovations. For example, one of the chapter authors worked in an assistive technology laboratory in which serial port add‐ons to computers evolved into Universal Serial Bus (USB) ports rendering the former connections and their attachments obsolete within in less than five years. Currently, com puters no longer come with disk drives and all of the software one needs to load on the computer comes from the cloud. Vicente (2006) stated, “... more and more technology is being foisted upon us at a faster and faster pace” (p. 13). In addition, technology is clearly a necessary part of our lives. For many of us, it is difficult to remember a time when cell phones, laptops, or navigation devices were not available to those who could afford it. Furthermore, the convergence of multiple technologies into a single, small, handheld device such as a smart phone is common as part of our work and personal experiencesآیا 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.
