Primera página: Vida de un periodista 1944-1988
by Juan Luis CebriánPrimera página son las memorias de Juan Luis Cebrián, primer director de El País, pero también el apasionante relato de los convulsos años que llevaron a España de una sangrienta y rancia dictadura a la democracia, contado por un testigo imprescindible. Nacido en Madrid en 1944, en una familia de periodistas, Juan Luis Cebrían pronto empezó a pisar las principales redacciones de la prensa de la época, primero la de Pueblo, luego la de Informaciones, donde fue subdirector con apenas 20 años, y también la de Cuadernos para el diálogo, cuyo espíritu fue un ensayo de la convivencia que haría posible la transición. Tras un fugaz paso por la dirección de informativos de RTVE, fue el primer director de El País, que pronto se convirtió en el periódico de referencia de España y símbolo de la reconquista de las libertades y la aspiración a una sociedad moderna y europea. Fueron años muy intensos que Cebrián vivió en primera línea, con secuestros de empresarios, atentados contra las redacciones, tensión en las calles, guerras soterradas por el control de un medio de comunicación que se hacía cada vez más poderoso, y hasta un golpe de Estado que amenazó con descarrilar el tren de la democracia. «Naturalmente, los hechos aquí relatados son todos ciertos, lo que no quiere decir que la versión de los mismos sea la única posible. He descrito mis relaciones con el poder, mis visiones profesionales, mis convicciones intelectuales. No pretendo que este sea un documento histórico, tampoco un ditirambo autocomplaciente ni emprender una saga de pequeñas venganzas contra nadie. Tampoco voy ahora a establecer verdades absolutas en las que no creo. Trato solo de explicar mis sentimientos, mis reacciones, mis apegos y desapegos en las vicisitudes varias en las que la vida me ha puesto.»Juan Luis Cebrián Primera página, que se lee con la tensión de una novela de aventuras, es un testimonio imprescindible de un periodo crucial de la historia reciente de España.
Principled Persuasion in Employee Communication
by Mike ChurchmanPrincipled Persuasion in Employee Communication highlights a new but significant dilemma for organisational leaders. Will they continue on the same track that, since the nineteenth century, has led them to exert increasing control over their employees? Or will they take another path, one that leads towards a new type of working environment where the culture encourages freedom of communication and movement? This book argues for an approach to employee communication that sets out to liberate employees from the stifling constraints that organisations continue to impose on them. Principled Persuasion is so-called because it uses persuasive techniques, based on clear principles, to create new, forward-looking organisational cultures. It sets out to increase employee happiness and minimise the harms done to employees at work. It grounds itself on a strong ethical base composed of fundamental, universal principles. It introduces a new approach to the use of language, not only calling for more clarity and meaning in organisational communication, but also for a more conscious use of rhetorical techniques to change vocabulary, metaphors and internal dialogue for the better. Make no mistake, most organisations have totally underrated the strategic importance of employee communication. Principled Persuaders understand that the key to dealing with the unpredictable events about to unfold in the twenty-first century will be a new way of communicating with the workforce. The flexibility, adaptability and innovation that will be needed to survive and prosper in coming decades can only be achieved by liberating employees, not imprisoning them further in established systems and processes.
Principles Of Digital Communication: A Top-Down Approach
by Bixio RimoldiThis comprehensive and accessible text teaches the fundamentals of digital communication via a top-down-reversed approach, specifically formulated for a one-semester course. The unique approach focuses on the transmission problem and develops knowledge of receivers before transmitters. In doing so it cuts straight to the heart of the digital communication problem, enabling students to learn quickly, intuitively, and with minimal background knowledge. Beginning with the decision problem faced by a decoder and going on to cover receiver designs for different channels, hardware constraints, design trade-offs, convolutional coding, Viterbi decoding, and passband communication, detail is given on system-level design as well as practical applications in engineering. All of this is supported by numerous worked examples, homework problems, and MATLAB simulation exercises to aid self-study, providing a solid basis for students to specialize in the field of digital communication and making it suitable for both traditional and flipped classroom teaching.

Privacy and Capitalism in the Age of Social Media (Routledge Research in Information Technology and Society #18)
by Sebastian SevignaniThis book explores commodification processes of personal data and provides a critical framing of the ongoing debate of privacy in the Internet age, using the example of social media and referring to interviews with users. It advocates and expands upon two main theses: First, people’s privacy is structurally invaded in contemporary informational capitalism. Second, the best response to this problem is not accomplished by invoking the privacy framework as it stands, because it is itself part of the problematic nexus that it struggles against. Informational capitalism poses weighty problems for making the Internet a truly social medium, and aspiring to sustainable privacy simultaneously means to struggle against alienation and exploitation. In the last instance, this means opposing the capitalist form of association – online and offline.

Professionalizing Public Relations
by Kate FitchThis groundbreaking study offers new insights into public relations history with a focus on the changing relationship between women and public relations, the institutionalization of public relations education, and the significance of globalization in Australia in the second half of the twentieth century. Drawing on archival and interview research, it reveals how the industry's professionalization led to the development of an occupational identity along national and gendered lines. It also challenges common misconceptions around the origins of public relations and women's early contributions and careers. Adopting a critical approach, Professionalizing public relations avoids corporatist perspectives on the historical development of public relations by focusing on the processes of professionalization and their significance for gender and education, and by situating this study in a broader global context. The findings reveal dynamic and contested conceptualizations of public relations knowledge and expertise, and the significance of historical processes for contemporary understandings of the industry.
Profile Pieces: Journalism and the 'Human Interest' Bias (Routledge Research in Journalism)
by Sue Joseph Richard Lance KeebleThis book examines the history, theory and journalistic practice of profile writing. Profiles, and the practice of writing them, are of increasing interest to scholars of journalism because conflicts between the interviewer and the subject exemplify the changing nature of journalism itself. While the subject, often through the medium of their press representative, struggles to retain control of the interview space, the journalist seeks to subvert it. This interesting and multi-layered interaction, however, has rarely been subject to critical scrutiny, partly because profiles have traditionally been regarded as public relations exercises or as ‘soft’ journalism. However, chapters in this volume reveal not only that profiling has, historically, taken many different forms, but that the idea of the interview as a contested space has applications beyond the subject of celebrated individuals. The volume looks at the profile’s historical beginnings, at the contemporary manufacture of celebrity versus the ‘ordinary’, at profiling communities, countries and movements, at profiling the destitute, at sporting personalities and finally at profiling and trauma.

Public Interests: Media Advocacy and Struggles over U.S. Television
by Allison PerlmanNearly as soon as television began to enter American homes in the late 1940s, social activists recognized that it was a powerful tool for shaping the nation's views. By targeting broadcast regulations and laws, both liberal and conservative activist groups have sought to influence what America sees on the small screen. Public Interests describes the impressive battles that these media activists fought and charts how they tried to change the face of American television. Allison Perlman looks behind the scenes to track the strategies employed by several key groups of media reformers, from civil rights organizations like the NAACP to conservative groups like the Parents Television Council. While some of these campaigns were designed to improve the representation of certain marginalized groups in television programming, as Perlman reveals, they all strove for more systemic reforms, from early efforts to create educational channels to more recent attempts to preserve a space for Spanish-language broadcasting. Public Interests fills in a key piece of the history of American social reform movements, revealing pressure groups' deep investments in influencing both television programming and broadcasting policy. Vividly illustrating the resilience, flexibility, and diversity of media activist campaigns from the 1950s onward, the book offers valuable lessons that can be applied to current battles over the airwaves.
Public Relations and Participatory Culture: Fandom, Social Media and Community Engagement (Routledge New Directions in PR & Communication Research)
by Amber Hutchins Natalie T.J. TindallWhile public relations practitioners have long focused on the relationship between organizations and their stakeholders, there has never been a time when that relationship was so dominated by public participation. The new model of multiple messages originating from multiple publics at varying levels of engagement is widely acknowledged, but not widely explored in scholarly texts. The established model of one-way communication and message control no longer exists. Social media and an increasingly participatory culture means that fans are taking a more active role in the production and co-creation of messages, communication, and meaning. These fans have significant power in the relationship dynamic between the message, the communicator, and the larger audience, yet they have not been defined using current theory and discourse. Our existing conceptions fail to identify these active and engaged publics, let alone understand virtual communities who are highly motivated to communicate with organizations and brands. This innovative and original research collection attempts to address this deficit by exploring these interactive, engaged publics, and open up the complexities of establishing and maintaining relationships in fan-created communities.
Public Relations and the Public Interest (Routledge Research in Public Relations)
by Jane JohnstonIn this book, Johnston seeks to put the public interest onto the public relations ‘radar’, arguing the need for its clear articulation into mainstream public relations discourse. This book examines literature from a range of fields and disciplines to develop a clearer understanding of the concept, and then considers this within the theory and practice of public relations. The book’s themes include the role of language and discourse in establishing successful public interest PR and in perpetuating power imbalances; intersections between CSR, governance, law and the public interest; and how activism and social media have invigorated community control of the public interest. Chapters explore the role of the public interest, including cross-cultural and multicultural challenges, community and internal consultation, communication choices and listening to minorities and subaltern publics.

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.
