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 experiences
Exporting the European Convention on Human Rights - Original PDF
نویسندگان: خلاصه: As for the right to protect one’s private and family life, as enshrined in Article 8 ECHR, the CJEU provided the very first explicit reference to the ECHR in Rutili v Minister for the Interior�53 In casu, the Convention was conceived as a source of inspiration as well as a human rights standard for determining the legality and legitimacy of the acts of Member States applying EU law. Therefore, the CJEU applied the ECHR as a clear human rights standard to also interpret the ‘public policy’ exception to the free movement of workers, justifying Member States to restrict this freedom only to the extent authorised by the ECHR, that is, when it is necessary for the protection of the interests of national security or public safety ‘in a democratic society’.54 This landmark case illustrates how the CJEU has progres- sively shaped its autonomous human rights case law, inspired, though, by the ECHR and by the common constitutional traditions of EU Member States.55 The Luxembourg Court established a much broader human rights review over their actions and paved the way for a much clearer reference to the Convention’s provi- sions as a material source of EU legal order, rather than a source of inspiration.56 Nonetheless, besides the consensus in this field, conflicts and inconsistencies between the two European jurisdictions have not been sidestepped. The main preoccupation of the following section is thus to unveil the extent to which the CJEU has directly referred to ECHR norms to protect private and family life57 with regard to the most controversial fields of data protection and migration/ asylum cases.
Housing Policy in the United States Fourth Editio - Original PDF
نویسندگان: خلاصه: 1 Introduction In its preamble to the 1949 Housing Act, Congress declared its goal of “a decent home in a suit- able living environment for every American family.” In the more than 60 years since this legisla- tion was passed, the federal government has helped fund the construction and rehabilitation of more than 5 million housing units for low-income households and provided rental vouchers to nearly 2 million additional families. Yet, the nation’s housing problems remain acute. In 2017, 44.7 million households lived in physically deficient housing, spent 30 percent or more of their income on housing, or were homeless (U.S. Census Bureau 2018; U.S. Department of Housing and Urban Development 2018). Put differently, about 113 million Americans—around 35 per- cent of the nation’s population and more than triple the 28.5 million lacking health insurance in 2017 (Berchick, Hood, & Barnett 2018)—confronted serious housing problems or had no housing at all.1 This book tells the story of how the United States has tried to address the nation’s housing problems. It looks at the primary policies and programs designed to make decent and affordable housing available to Americans of modest means. It examines the strengths and weaknesses of these policies and programs and the challenges that still remain. The book takes a broad view of housing policy, focusing not only on specific housing subsidy programs, such as public housing, but also on the federal income tax code and regulations affecting mortgage lending, land use decisions, real estate transactions, and other activities integral to the housing market. Some of these broader aspects of housing policy provide financial incentives for investments in affordable housing, others attempt to make housing available to low-income and minority households and communities by penalizing discriminatory practices and through other regulatory interventions. Put simply, then, this book is about policies and programs designed to help low-income and other disadvantaged individuals and households access decent and affordable housing. It examines programs and policies that subsidize housing for low-income households or that attempt to break down institutional barriers, such as discriminatory practices in the real estate industry that impede access to housing. The book is intended to be a general overview of housing policy. It is beyond its scope to delve deeply into programmatic details or to cover all aspects of the field in equal depth. The focus is on federal and, to a lesser degree, state and local programs and policies that subsidize housing for low-income households or otherwise attempt to make housing accessible to this population. Much less attention is given to policies concerned with the physical aspects of housing, such as design standards and building regulations—except when they are explicitly employed to promote affordable housing. The book does not examine in detail the operation of housing markets or pro- vide a comprehensive legislative history of housing policy.
