Mainstream economics traditionally restricts the analysis of the labor market to purely monetary factors, such as earnings, leaving aside many other characteristics which might affect the desirability of certain jobs. By contrast, this original book aims to explore the alternatives and problems faced by researchers in quantifying and measuring a broader notion of job quality. The main objective is to analyze the different approaches to measurement and to analyze both the advantages and disadvantages of the various methods within a European context. Specifically, the book presents a unique new index of job quality and applies it to the EU Member States. The index proves particularly useful to measure the differences in job quality by country, occupation, gender and age. Based on solid theory and data, this book will prove essential for postgraduate students, researchers and academics of labor economics, sociology, industrial relations, and European studies as it presents a coherent discussion of the concept and components of job quality, and of the difficulties of measuring it. The book also proposes a new aggregate index of job quality that can contribute to the evaluation of European employment policies and performance that will appeal to European policy circles.

In 1624 the German erudite Kaspar Barth translated the Spanish book Celestina (1499) into Neo-Latin with the title Pornoboscodidascalus (""teacher of the brothel master""). The translation, intended for the cultivated readers who still used Latin as their lingua franca, contained an extensive prologue and numerous translation notes. This first critical edition of Barth's translation is a valuable tool not only for Celestina scholars, but also for Neo-Latin scholars and for those interested in the history of translation and in early modern Europe. With such a wide readership in mind, the edition contains the transcription of the Neo-Latin text, as well as the English translation of Barth's prologue and notes. It also includes a critical apparatus, notes with full references to the sources quoted by Barth, and an introduction to the most relevant aspects of Barth's translation.

Differential equations can be viewed as a tool well suited to bring mathematics closer to real life and describe phenomena with an origin in physics, chemistry, biology, economics, etc. Of course, this 'invites' scientists and engineers to use them.On the other hand, differential equations are at the starting point of a lot of purely mathematical activity. Thus, a large part of functional analysis has been motivated by the need to solve questions coming from the analysis of differential systems. The same can be said of numerical analysis. Also, we must remember the relevant role played by differential equations in the formulation and resolution of problems in harmonic analysis, differential geometry, probability calculus, etc.Consequently, the interest in differential equations is justified from a double viewpoint: as significative and inspiring examples of questions and results arising in many areas in mathematics and also as a machinery that must be well understood in order to apply mathematics to real world problems.The main goal of this book is to provide a rigorous introduction to the theoretical study of this important tool and, also, to demonstrate its utility with applications coming from many fields.The book has its origin in several 'classical' or 'standard' courses given by the author for decades at the University of Sevilla. It has been an objective to make compatible the rigor of the underlying mathematical theory and the richness of applicability. Thus, together with existence, uniqueness, regularity, continuous dependence on data and parameters, etc., permanent interpretation of the laws, the role of the data, the behaviour of the solutions and other elements are discussed. Although briefly, the connections to first order partial differential equations and control and optimization have also been indicated.Each chapter has been completed with a collection of exercises, many of them with useful hints.

Este trabajo de investigacion se realizo en el micro cuenca del Rio Paria del Distrito de Independencia, provincia de Huaraz del Departamento de Ancash. Los objetivos del trabajo de investigacion fueron: Determinar el valor marginal de los recursos hidricos que provee la Cuenca del Rio Paria, por parte del poblador y Establecer el uso adecuado del recurso hidrico en la Cuenca del Rio Paria para garantizar su conservacion en la cuenca del rio Paria, durante el ano 2010, para ello se realizaron diversas encuenstas. De acuerdo a la investigacion y los resultados obtenidos; se comprueba con el Analisis Chi Cuadrado que la hipotesis nula "Ho" es rechazada, siendo la hipotesis alterna "H1" aceptada por el valor calculado 5.190 es mayor que el valor critico 3.841, significando esto que el proceso de la eficiente valorizacion marginal basada en: capacitacion; talleres por personal tecnico y profesional permitiria que el poblador tenga un uso adecuado y racional del recurso hidrico."

Con la creciente dependencia que la sociedad de la informacion tiene de las Tecnologias de la Informacion y las Comunicaciones (TIC), la necesidad de proteger la informacion tiene cada vez mayor importancia para las empresas. De esta manera, la demanda de productos, sistemas y servicios para gestionar y mantener la informacion es creciente, y no es suficiente con realizar unos controles de seguridad superficiales. Es necesario aplicar un enfoque riguroso para evaluar y mejorar la seguridad de los productos y tambien de los procesos que se llevan a cabo en el contexto de las TIC. En este contexto, surgen los Sistemas de Gestion de la Seguridad de la Informacion (SGSI), que tienen una gran importancia para la estabilidad de los sistemas de informacion de las companias. El hecho de poder disponer de estos sistemas ha llegado a ser cada vez mas vital para la evolucion de las PYMES."
