Politics and the Twitter Revolution: How Tweets Influence the Relationship between Political Leaders and the Public by John H. Parmelee and Shannon L.

Uno de los principales cuestionamientos a la comunicación fue siempre la supeditación de los intereses de las grandes empresas de comunicación en desmedro de la libertad periodística. La empresa de comunicación fue, junto a los poderes políticos y económicos, uno de los verdugos al ideal del periodismo, la libertad de expresión.

La innovación es crucial para potenciar la capacidad que tiene una empresa de crear una ventaja competitiva sostenible que le permita sobrevivir en un contexto casi siempre complejo y plagado de retos.

Technological, cultural and economic forces are transforming political communication, posing challenges and opportunities for politicians and media organisations, while at the same time many governments and civil society express concerns about the extent and nature of political empowerment and civic engagement. This book offers an international perspective on current thinking and practice about civic and audience empowerment, focusing on the ways and means through which media can empower or dis-empower citizens as audiences. It features theoretical and empirical chapters that draw specific attention to a reappraisal of the theories, methods and issues that inform our understanding of citizen...
This book provides an overview of beach management tools, including carrying capacity, beach nourishment, environmental and tourism awards (like Blue Flag or others), bathing water quality, zoning, beach typologies, quality index, user's perception, interdisciplinary beach monitoring, coastal legislation, shore protection, social and economic indicators, ecosystem services, and coastal governance (applied in beach case studies). Beaches are one of the most intensely used coastal ecosystems and are responsible for more than half of all global tourism revenues, and as such the book introduces a wide range of state-of-the-art tools that can be used to deal with a variety of beach challenges. Each chapter features specific types of tools that can be applied to advantage in beach management practices. With examples of local and regional case studies from around the globe, this is a valuable resource for anyone involved in beach management.
The book brings together contributions from over 35 Portuguese geomorphologists, presenting a thorough overview of the main highlights of the landscape of Portugal's mainland, Azores and Madeira. The book, which is a tribute to Professor António de Brum Ferreira, first President of the Portuguese Association of Geomorphologists and former Professor at the University of Lisbon, who passed away in January 2013, is organized in 3 parts: a) Introduction, which presents a general framework of the physical geography of Portugal, b) Geomorphological landscapes, presenting ca. 30 short papers with regional focus on key geomorphological areas, c) Applied geomorphology, providing an updated vision on the protection of geomorphological heritage with a focus on geoparks, as well as on Geomorphological hazards in Portugal. This first book ever to concentrate on the geomorphology of Portugal will surely become a benchmark for Portuguese geomorphology.
The objective of this book is to provide the fundamental comprehension of a broad range of topics in an integrated volume such that readership hailing from diverse disciplines can rapidly acquire the necessary background for applying it in pertinent research and development field.
