Portfolio theory and much of asset pricing, as well as many empirical applications, depend on the use of multivariate probability distributions to describe asset returns. Traditionally, this has meant the multivariate normal (or Gaussian) distribution. More recently, theoretical and empirical work in financial economics has employed the multivariate Student (and other) distributions which are members of the elliptically symmetric class. There is also a growing body of work which is based on skew-elliptical distributions. These probability models all exhibit the property that the marginal distributions differ only by location and scale parameters or are restrictive in other respects. Very often, such models are not supported by the empirical evidence that the marginal distributions of asset returns can differ markedly. Copula theory is a branch of statistics which provides powerful methods to overcome these shortcomings. This book provides a synthesis of the latest research in the area of copulae as applied to finance and related subjects such as insurance. Multivariate non-Gaussian dependence is a fact of life for many problems in financial econometrics. This book describes the state of the art in tools required to deal with these observed features of financial data. This book was originally published as a special issue of the European Journal of Finance.

PURA BELPRE HONOR BOOK ALA NOTABLE BOOK "An important, must-have addition to the growing body of literature with immigrant themes." --School Library Journal (starred review) Twelve-year-old Jaime makes the treacherous and life-changing journey from his home in Guatemala to live with his older brother in the United States in this "powerful and timely" (Booklist, starred review) middle grade novel. Jaime is sitting on his bed drawing when he hears a scream. Instantly, he knows: Miguel, his cousin and best friend, is dead. Everyone in Jaime's small town in Guatemala knows someone who has been killed by the Alphas, a powerful gang that's known for violence and drug trafficking. Anyone who refuses to work for them is hurt or killed--like Miguel. With Miguel gone, Jaime fears that he is next. There's only one choice: accompanied by his cousin Angela, Jaime must flee his home to live with his older brother in New Mexico. Inspired by true events, The Only Road is an individual story of a boy who feels that leaving his home and risking everything is his only chance for a better life. The story is "told with heartbreaking honesty," Booklist raved, and "will bring readers face to face with the harsh realities immigrants go through in the hope of finding a better, safer life, and it will likely cause them to reflect on what it means to be human."

Este ensaio propoe a novela grafica como um genero literario, tendo como eixo estruturador a obra teorica de Rodolph Toepffer, e o seu conceito de literatura em estampas, um novo genero escrito atraves de texto e imagem. Centrado nos generos narrativos, dara especial destaque ao romance, cuja forma proteica permite assimilar novas formas romanescas, nomeadamente a novela grafica. No universo da novela grafica, a adaptacao de obras literarias, para alem de constituir uma pratica corrente, definida pelos historiadores como uma das suas "tendencias" mais marcantes do curso da historia da banda desenhada portuguesa, e um fator decisivo para a constituicao do genero.
