Old Norse Mythology

  • Publisher: Unknown

An innovative and accessible overview of how ancient Scandinavians understood and made use of their mythological stories. Old Norse Mythology provides a unique survey of the mythology of Scandinavia: the gods Þórr (Thor) with his hammer, the wily and duplicitous Óðinn (Odin), the sly Loki, and other fascinating figures. They create the world, battle their enemies, and die at the end of the world, which arises anew with a new generation of gods. These stories were the mythology of the Vikings, but they were not written down until long after the conversion to Christianity, mostly in Iceland. In addition to a broad overview of Nordic myths, the book presents a case study of one myth, which tells of how Þórr (Thor) fished up the World Serpent, analyzing the myth as a sacred text of the Vikings. Old Norse Mythology also explores the debt we owe to medieval intellectuals, who were able to incorporate the old myths into new paradigms that helped the myths to survive when they were no longer part of a religious system. This superb introduction traces the use of the mythology in ideological contexts, from the Viking Age until the twenty-first century, as well as in entertainment.

The last two years have seen significant developments in the standardization of GMPLS and its implementation in optical and other networks. GMPLS: Architecture and Applications brings you completely up to date, providing the practical information you need to put the growing set of GMPLS-supported services to work and manage them effectively. This book begins by defining GMPLS’s place in a transport network, leveraging your knowledge of MPLS to give you an understanding of this radically new control plane technology. An overview of GMPLS protocols follows, but the real focus is on what comes afterwards: in-depth examinations of the architectures underpinning GMPLS in real-world network envi...

Electrocatalysis in Balancing the Natural Carbon Cycle

Electrocatalysis in Balancing the Natural Carbon Cycle Explore the potential of electrocatalysis to balance an off-kilter natural carbon cycle In Electrocatalysis in Balancing the Natural Carbon Cycle, accomplished researcher and author, Yaobing Wang, delivers a focused examination of why and how to solve the unbalance of the natural carbon cycle with electrocatalysis. The book introduces the natural carbon cycle and analyzes current bottlenecks being caused by human activities. It then examines fundamental topics, including CO2 reduction, water splitting, and small molecule (alcohols and acid) oxidation to prove the feasibility and advantages of using electrocatalysis to tune the unbalanced...

Push Factors and Capital Flows to Emerging Markets

Push Factors and Capital Flows to Emerging Markets

This paper analyzes the behavior of gross capital inflows across 34 emerging markets (EMs). We first confirm that aggregate inflows to EMs co-move considerably. We then report three findings: (i) the aggregate co-movement conceals significant heterogeneity across asset types as only bank-related and portfolio bond and equity inflows do co-move; (ii) while global push factors in advanced economies mostly explain the common dynamics, their relative importance varies by type of flow; and (iii) the sensitivity to common dynamics varies significantly across borrower countries, with market structure characteristics (especially the composition of the foreign investor base and the level of liquidity) rather than borrower country’s institutional fundamentals strongly affecting sensitivities. Countries relying more on international funds and global banks are found to be more sensitive to push factors. Our findings suggest that EMs need to closely monitor their lenders and investors to assess their inflow exposures to global push factors.

International Capital Flow Pressures

International Capital Flow Pressures

This paper presents a new measure of capital flow pressures in the form of a recast Exchange Market Pressure index. The measure captures pressures that materialize in actual international capital flows as well as pressures that result in exchange rate adjustments. The formulation is theory-based, relying on balance of payments equilibrium conditions and international asset portfolio considerations. Based on the modified exchange market pressure index, the paper also proposes the Global Risk Response Index, which reflects the country-specific sensitivity of capital flow pressures to measures of global risk aversion. For a large sample of countries over time, we demonstrate time variation in the effects of global risk on exchange market pressures, the evolving importance of the global factor across types of countries, and the changing risk-on or risk-off status of currencies.

Portfolio Inflows Eclipsing Banking Inflows: Alternative Facts?

Superficial examination of aggregate gross cross-border capital inflow data suggests that there was no substitution between portfolio inflows and bank loans in recent years. However, our novel analysis of disaggregate inflows (both by types of instrument and borrower) shows interesting heterogeneity. There has been substitution of bank loans for portfolio debt securities not only in the case of corporate and sovereign borrowers in advanced countries, but also sovereign borrowers in emerging countries. In the case of corporate borrowers in emerging markets, the relationship corresponds to complementarity across types of gross capital inflows, especially during periods of positive capital gross inflows after the global financial crisis. A large part of these patterns does not seem to be driven by a common phenomenon across countries associated with the global financial cycle, but rather by country-specific factors.

  • Publisher: SIAM

Nonnegative matrix factorization (NMF) in its modern form has become a standard tool in the analysis of high-dimensional data sets. This book provides a comprehensive and up-to-date account of the most important aspects of the NMF problem and is the first to detail its theoretical aspects, including geometric interpretation, nonnegative rank, complexity, and uniqueness. It explains why understanding these theoretical insights is key to using this computational tool effectively and meaningfully. Nonnegative Matrix Factorization is accessible to a wide audience and is ideal for anyone interested in the workings of NMF. It discusses some new results on the nonnegative rank and the identifiability of NMF and makes available MATLAB codes for readers to run the numerical examples presented in the book. Graduate students starting to work on NMF and researchers interested in better understanding the NMF problem and how they can use it will find this book useful. It can be used in advanced undergraduate and graduate-level courses on numerical linear algebra and on advanced topics in numerical linear algebra and requires only a basic knowledge of linear algebra and optimization.

International Electronic Evidence

An increasing number of civil and criminal proceedings involve the use of digital evidence across jurisdictional boundaries. Digital evidence now affects every aspect of law, including contract, employment, family, crime, intellectual property, and land law. In effect, no area of law is excluded, and digital evidence has become of greater importance now that the Internet has become ubiquitous. It is increasingly apparent that criminals and terrorists target the electronic environment in order to steal, to carry out extortion, and to abuse children across jurisdictions. Additionally, both public and commercial organizations now rely on the digital environment to such an extent that it has bec...
