La evolución social ha alterado en gran medida los criterios de separación entre el derecho privado y el derecho público tal como fueron fijados en el Digesto y ha producido una fecunda interacción del Derecho civil y el Derecho administrativo en ámbitos como la protección del consumidor, el urbanismo, la contratación pública, la responsabilidad patrimonial o el dominio público. Ante los tribunales de justicia esta división cobra una especial dimensión pero resulta atenuada al estar sometidos los jueces a este principio universal: la justicia no puede negarse a nadie. Es en estos ámbitos fronterizos, de la extranjería, la protección de datos, la gestación subrogada, la e...
"Wildlife in a Changing World" presents an analysis of the 2008 IUCN Red List of Threatened Species. Beginning with an explanation of the IUCN Red List as a key conservation tool, it goes on to discuss the state of the world s species and provides the latest information on the patterns of species facing extinction in some of the most important ecosystems in the world, highlighting the reasons behind their declining status. Areas of focus in the report include: freshwater biodiversity, the status of the world s marine species, species susceptibility to climate change impacts, the Mediterranean biodiversity hot spot, and broadening the coverage of biodiversity assessments."
A reference guide to the vast array of art song literature and composers from Latin America, this book introduces the music of Latin America from a singer's perspective and provides a basis for research into the songs of this richly musical area of the world. The book is divided by country into 22 chapters, with each chapter containing an introductory essay on the music of the region, a catalog of art songs for that country, and a list of publishers. Some chapters include information on additional sources. Singers and teachers may use descriptive annotations (language, poet) or pedagogical annotations (range, tessitura) to determine which pieces are appropriate for their voices or programming needs, or those of their students. The guide will be a valuable resource for vocalists and researchers, however familiar they may be with this glorious repertoire.
This book endeavours to pinpoint the relations between musical, and especially instrumental, practice and the evolving conceptions of pitch systems. It traces the development of ancient melodic notation from reconstructed origins, through various adaptations necessitated by changing musical styles and newly invented instruments, to its final canonical form. It thus emerges how closely ancient harmonic theory depended on the culturally dominant instruments, the lyre and the aulos. These threads are followed down to late antiquity, when details recorded by Ptolemy permit an exceptionally clear view. Dr Hagel discusses the textual and pictorial evidence, introducing mathematical approaches wherever feasible, but also contributes to the interpretation of instruments in the archaeological record and occasionally is able to outline the general features of instruments not directly attested. The book will be indispensable to all those interested in Greek music, technology and performance culture and the general history of musicology.

There is a rapidly growing interest in, and demand for, non-timber forest products (NTFPs). They provide critical resources across the globe fulfilling nutritional, medicinal, financial and cultural needs. However, they have been largely overlooked in mainstream conservation and forestry politics. This volume explains the use and importance of certification and eco-labelling for guaranteeing best management practices of non-timber forest products in the field. Using extensive case studies and global profiles of non-timber forest products, this work not only seeks to further our comprehension of certification processes but also broaden understanding of non-timber forest product management, harvesting and marketing. It should be useful to forest managers, policy-makers and conservation organizations as well as for academics in these areas.
