Por primera vez en nuestra disciplina laboral, un libro estudia la dimensión temporal del convenio colectivo, analizando importantes problemas -como los requisitos formales que determinan la vigencia del convenio colectivo, la ultraactividad, la prórroga, la denuncia o la nulidad- y ofreciendo pautas para interpretar estas controversias con el fin de reducir el elevado grado de inseguridad jurídica que tienen los diversos operadores jurídico-laborales sobre la mayoría de ellas.El autor desarrolla una completa visión no sólo del convenio colectivo sino del propio sistema negocial, de sus diferentes "estadios vitales" y de los problemas que suscita, realizando un estudio jurisprudencial y doctrinal de las principales cuestiones prácticas que plantea la vigencia convencional en la dinámica de nuestras relaciones laborales.

This edition of the World Bank has been revised and expanded by the Terminology Unit in the Languages Services Division of the World Bank in collaboration with the English, Spanish, and French Translation Sections. The Glossary is intended to assist the Bank's translators and interpreters, other Bank staff using French and Spanish in their work, and free-lance translator's and interpreters employed by the Bank. For this reason, the Glossary contains not only financial and economic terminology and terms relating to the Bank's procedures and practices, but also terms that frequently occur in Bank documents, and others for which the Bank has a preferred equivalent. Although many of these terms, relating to such fields as agriculture, education, energy, housing, law, technology, and transportation, could be found in other sources, they have been assembled here for ease of reference. A list of acronyms occurring frequently in Bank texts (the terms to which they refer being found in the Glossary) and a list of international, regional, and national organizations will be found at the end of the Glossary.

The Andes are attracting global interest again: they hold valuable mineral resources, tourists appreciate their great natural beauty and the diversity of indigenous cultures, climbers scale rock and ice faces, while many others are intrigued by regional political developments, such as the Bolivarian revolution in Venezuela or the almost unfettered hegemony of the neoliberal economic model in Chile. This volume is the first attempt for decades to present a complete overview of the longest mountain chain on the planet – a region of remarkable climatic, floristic and geologic diversity, where advanced civilization developed well before the arrival of the Spanish. Today the Andes continue to be characterized by their ethnic, demographic, cultural and economic diversity, as well as by the disparity of local socioeconomic groups. The Andean countries pursue a wide range of approaches to tackle the challenges of making the best use of their natural and cultural potential without damaging their ecological basis, as well as to overcome economic disparity and foster social cohesion. This book provides insights into this unique region and its most pressing issues, complemented by a wealth of pictures and comprehensive diagrams, which, in sum, help to better understand these fascinating mountains.
