Public Service Broadcasting Online
by Benedetta BreviniThis book investigates the extent to which a Public Service Broadcasting (PSB) ethos has been extended to the online world in Europe. It examines the most significant policy initiatives carried out by PSBs in Europe on online platforms, and analyzes how the public service philosophy is being reinvented by policy makers.
Public Spheres and Mediated Social Networks in the Western Context and Beyond
by Mark Wheeler Petros IosifidisSocial media is said to radically change the way in which public communication takes place: information diffuses faster and can reach a large number of people, but what makes the process so novel is that online networks can empower people to compete with traditional broadcasters or public figures. This book critically interrogates the contemporary relevance of social networks as a set of economic, cultural and political enterprises and as a public sphere in which a variety of political and socio-cultural demands can be met. It examines policy, regulatory and socio-cultural issues arising from the transformation of communication to a multi-layered sphere of online and social networks. The central theme of the book is to address the following questions: Are online and social networks an unstoppable democratizing and mobilizing force? Is there a need for policy and intervention to ensure the development of comprehensive and inclusive social networking frameworks? Social media are viewed both as a tool that allows citizens to influence policymaking, and as an object of new policies and regulations, such as data retention, privacy and copyright laws, around which citizens are mobilizing.
Public Transport Optimization
by Konstantinos GkiotsalitisThis textbook provides a comprehensive step-by-step guide for new public transport modelers. It includes an introduction to mathematical modeling, continuous and discrete optimization, numerical optimization, computational complexity analysis, metaheuristics, and multi-objective optimization. These tools help engineers and modelers to use better existing public transport models and also develop new models that can address future challenges. By reading this book, the reader will gain the ability to translate a future problem description into a mathematical model and solve it using an appropriate solution method.The textbook provides the knowledge needed to develop highly accurate mathematical models that can serve as decision support tools at the strategic, tactical, and operational planning levels of public transport services. Its detailed description of exact optimization methods, metaheuristics, bi-level, and multi-objective optimization approaches together with the detailed description of implementing these approaches in classic public transport problems with the use of open source tools is unique and will be highly useful to students and transport professionals.
