Geography of Happiness A Spatial Analysis of Subjective Well-Being - Original PDF
نویسندگان: خلاصه: Recent advances in spatial analysis have led to a growing interest in applying geocomputation methods to complex issues (Du et al., 2020), often defined over large datasets framing socioeconomic variables (Ekbia et al., 2015) and the natural environment (Bryan et al., 2011). Much of this work has been carried out to optimize decision-making and lead to a better quality of life, economic growth and social stability (Higgins et al., 2014; Rosu et al., 2015; Ahlfeldt et al., 2020). Thanks to the advances of computational power, spatial analysis has reached a new stage, where nonlinear modelling approaches combined with stochastic modelling allow for a better understanding of the geographical environment (Silva et al., 2020) and there- fore foster more accurate decision-making (Carver, 2019). This decision-making has focused predominantly on sustainable development, leading to better life quality, where spatial information on the natural environment has brought a key role, partic- ularly in ecology, to understand the present and offer a more sustainable future. From an anthropocentric perspective, wellbeing is the relation of humankind’s social, economic, and environmental stability, maximizing the opportunities for sustainable development while leading to better life quality. This holistic approach of wellbeing closely rem
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
The Emergence of a Tradition: Essays in Honor of Jesús Huerta de Soto, Volume II Philosophy and Political Economy - Original PDF
نویسندگان: خلاصه: Only a small minority of people, in our experience, know what Jesús’s full name is. Due to some idiosyncrasies of Spanish naming conventions, this group is dominated by Spaniards. To aid the non-Spanish speaker, a brief explanation of his name is necessary. All Spanish surnames are composed of two parts. The first part is the father’s first surname, and the sec- ond is the mother’s first surname. The general form for all Spanish names becomes [first name] [paternal first surname] [maternal first surname]. Thus, all children have a different surname than their mothers and fathers, though this surname will include elements of both through their respective paternal branches. The children of Juan Garcia Fernandez and Sofia Gonzalez Martin, for example, would all have the surname Garcia Gonzalez. Jesús Huerta de Soto Ballester was born to Jesús Huerta Ballester and Concepción de Soto Acuña. His birth name was Jesús Huerta de Soto, and (after marrying Sonsoles Huarte) his children would have the surname Huerta Huarte. With six children, this linguistically challenging surname would have not been an isolated difficulty. After marriage, Jesús made the decision to legally change the order of his surnames. (This bureaucratic process is not straightforward, nor is it common.) As a result of this change, his first surname, Huerta de Soto, now includes elements of both his father’s and his mother’s names. His second surname, Ballester, is from his father. While the name remains essentially the same (Jesús Huerta de Soto at birth versus Jesús Huerta de Soto Ballester today), the change in ordering meant that the family name passed down to his children would be “Huerta de Soto” instead of “Huerta.” This also applies to their descendants. In all but the most formal situations in Spain, use of only the first surname
Global Economic Challenges 6th International Conference on Banking and Finance Perspectives, Cuenca, Spain - Original PDF
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.
Environmental Regulations and Industrial Competitiveness Case Studies of Toxic Industries in Southern California - Original PDF
نویسندگان: خلاصه: 1 Chapter 1 Environmental Regulations and Industrial Competitiveness Abstract Industries in the U.S. emit billions of pounds of toxic chemicals into the environment every year, resulting in a major risk to human health. Many economists and policy makers, however, are strongly opposed to environmental regulations based on an assumption that regulations lead to a loss of jobs and a declining stan- dard of living for U.S. citizens. The empirical literature on this question has pro- duced mixed results, and this chapter critically assesses several conceptual and methodological issues that are embedded in this literature. Our thesis is that strin- gent environmental regulations have the potential to effectively and efficiently reduce toxic emissions from polluting firms and industries while having a negligible impact on the economic competitiveness of firms and industries. We investigate this thesis through three empirical case studies of polluting industries in Southern California that are highly regulated by the South Coast Air Quality Management District (AQMD): metal finishing, wood furniture, and dry cleaning. We also attempt to reveal the institutional process by which firms comply with environmen- tal regulations. Keywords Environmental regulations · Economic competitiveness · Environmental pollution · Economic externalities · Market failure · Environmental compliance · Technological uncertainty · Innovation · Adoption Introduction Over the last half century, the US federal government has played an active role in regulating the emission of toxic chemicals from polluting firms and industries (Rosenbaum, 2019; Telsey, 2016). Congress passed the Clean Air Act of 1970 “to protect and enhance the quality of the nation’s air resources so as to promote the public health and welfare and the productive capacity of the population” (US Environmental Protection Agency, 2007, p. 2). Congress also created the EPA (Environmental Protection Agency) in 1970 to implement and enforce the nation’s environmental law
Disaster Management and Information Technology Professional Response and Recovery Management in the Age of Disasters - Original PDF
نویسندگان: خلاصه: There is no one single journey when it comes to technology. For those who did not grow up as “digital natives” each has taken their own path in accepting, developing technological skills and expanding them by integrating them into their everyday work environment. Indeed, the journey continues with no hard- set destination before us. We only know that technological development and use of technology continue to expand exponentially with each passing day. What follows is therefore just one American perspective on how the profession of emergency management has adopted technologies over the decades in which the profession has existed. All the while, working daily to plan for, train, and practice for future emergency and disaster response events that are sure to come.

Blockchain Technology and Emerging Technologies - Original PDF
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 solutions
Iron Oxides by Damien Faivre - PDF
نویسندگان: خلاصه: As the name of the book “Iron oxides: from nature to applications” suggests, iron oxides are not only widespread in the environment, but also widely used by mankind in a variety of applications (Figure 1.1). Both this ubiquitous presence in nature and the utilization as tools have been established for cen- turies and are still valid today. The first illustrative examples of iron oxides certainly are compass needle or rust (Figure 1.2). Iron oxides are present in solid, liquid, and gaseous environments, with respective examples such as rocks, as mineral inclusion in swimming bacteria or in aerosols. Depending on the type of use, several sources of iron oxides exist. Applications range from the heavy steel production to medicine and art. The different aspects of mineral formation and their use as well as modern characterization techniques are reviewed in this book
Essentials of Flow Assurance Solids in Oil and Gas Operations Understanding Fundamentals, Characterization, Prediction, Environmental Safety, and Managemen - Original PDF
نویسندگان: خلاصه: ntroduction Oil and gas were formed over millions of years from the dead bodies of plankton (tiny marine organ- isms). These prehistoric dead plankton and their naturally engineered product have dominated and shaped modern times into “the Great Oil Age,” as McKenzie-Brown, Jaremko, and Finch titled their book on the subject [1]. Petroleum shapes our modern times in two main ways: first by serving as the main source of energy, and secondly by being the raw material for thousands of products that play critical roles in modern civilization. Fossil fuels still constitute the major global source of energy, despite the recent advances in renew- able sources of energy. Fossil fuels represent 85% of global primary energy consumption [2,3], with oil remaining as the most used source in the energy mix (33%–34%), as shown in Fig. 1.1. The global consumption of and demand for hydrocarbons (oil and gas) outweigh that of other sources of energy such as coal, nuclear, and renewable energies, due to the fast-growing population and newly emerging technologies. The global energy demand is projected to more than double by 2050 due to the growth in population and economies [4]. The demand for gas is growing faster than the demand for oil, especially in developing countries [5,6]آیا 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.
