The wild inside story of the birth of CNN and dawn of the age of 24-hour news. How did we get from an age of dignified nightly news broadcasts on three national networks to the age of 24-hour channels and constantly breaking news? The answer-thanks to Ted Turner and an oddball cast of cable television visionaries, big league rejects, and nonunion newbies-can be found in the basement of an abandoned country club in Atlanta. Because it was there, in the summer of 1980, that this motley crew somehow, against all odds, launched CNN. Lisa Napoli's Up All Night is an entertaining inside look at the founding of the upstart network that set out to change the way news was delivered and consumed. Mixing media history, a business adventure story, and great characters, Up All Night tells the story of a network that succeeded beyond even the wildest imaginings of its charismatic and uncontrollable founder, and paved the way for the world we live in today.

Although the "decline" of network television in the face of cable programming was an institutional crisis of television history, John Caldwell's classic volume Televisuality reveals that this decline spawned a flurry of new production initiatives to reassert network authority. Television in the 1980s hyped an extensive array of exhibitionist practices to raise the prime-time marquee above the multi-channel flow. Televisuality demonstrates the cultural logic of stylistic exhibitionism in everything from prestige series (Northern Exposure) and "loss-leader" event-status programming (War and Remembrance) to lower "trash" and "tabloid" forms (Pee-Wee's Playhouse and reality TV). Caldwell shows how "import-auteurs" like Oliver Stone and David Lynch were stylized for prime time as videographics packaged and tamed crisis news coverage. By drawing on production experience and critical and cultural analysis, and by tying technologies to aesthetics and ideology, Televisuality is a powerful call for desegregation of theory and practice in media scholarship and an end to the willful blindness of "high theory."

"Volume 6 of The Year in C-SPAN Archives Research series focuses on the rapidly changing rhetoric coloring American politics. An increasingly polarized electorate combined with advances in technology have led to a combative and pitched rhetoric through more and more outlets. Each chapter is interdisciplinary in nature, drawing on communication studies, political science, history, and other fields. Using the extensive collection of the C-SPAN Video Library, chapters cover the highly visible Thomas and Kavanaugh judicial nomination hearings as well as the ongoing debate around impeachment. Other pieces focus on the rhetoric of the 2008 Wall Street crisis, presidential campaign announcements, White House press conferences, floor time by women in the House of Representatives, the use of Twitter by legislators, and the puzzle of zero population growth. Collectively, they paint a picture of how Congress and the president approach the broad topic of political rhetoric using C-SPAN video as the basis for their research. The C-SPAN Video Library is unique because there is no other research collection that is based on video research of contemporary politics. Methodologically distinctive, much of the research uses new techniques to analyze video, text, and spoken words of political leaders. No other book examines such a wide range of topics -- from immigration to climate change to race relations -- using video as the basis for research." --

Passive vibration control plays a crucial role in structural engineering. Common solutions include seismic isolation and damping systems with various kinds of devices, such as viscous, viscoelastic, hysteretic, and friction dampers. These strategies have been widely utilized in engineering practice, and their efficacy has been demonstrated in mitigating damage and preventing the collapse of buildings, bridges, and industrial facilities. However, there is a need for more sophisticated analytical and numerical tools to design structures equipped with optimally configured devices. On the other hand, the family of devices and dissipative elements used for structural protection keeps evolving, because of growing performance demands and new progress achieved in materials science and mechanical engineering. This Special Issue collects 13 contributions related to the development and application of passive vibration control strategies for structures, covering both traditional and innovative devices. In particular, the contributions concern experimental and theoretical investigations of high-efficiency dampers and isolation bearings; optimization of conventional and innovative energy dissipation devices; performance-based and probability-based design of damped structures; application of nonlinear dynamics, random vibration theory, and modern control theory to the design of structures with passive energy dissipation systems; and critical discussion of implemented isolation/damping technologies in significant or emblematic engineering projects.

This book examines the reasons behind the declining fortunes of public access channels. Public access, which provided perhaps the boldest experiment in popular media democracy, is in steep decline. While some have argued it is technologically outmoded, Caterino argues that the real reason lies with the rise of a neo-liberal media regime. This regime creates a climate in which we can understand these changes. This book considers the role of neo-liberalism in transforming notions of public obligations and regulation of media that have impacted non-profit media, specifically public access. Neo-liberalism has tried to eliminate public forums and public discourse and weakens institutions of civil society. Though social media is often championed as an arena of communicative freedom, Caterino argues that neo-liberalism has created a colonized social media environment that severely limits popular democracy.

Dejan Petkov explores the tramway renaissance in Western Europe from a socio-technical standpoint and focuses on the development in Germany, France, and England. A multiple case analysis reveals the drivers, impact forces, actors and interest constellations behind the tramway renaissance in these countries and demonstrates the large variations in local systems and their style. A key finding is that there can be quite different paths to the success of tramway systems, but this success usually comes at a cost and can have a comprehensive character only if the systems are considered an integral part of the overarching strategies and concepts for urban and regional development. Contents A socio-technical framing of the tramway renaissance Characteristics of the international tramway renaissance The gradual and multifaceted development of tramway systems in Germany The emergence of the modern French tramway as a socio-technical novelty The uneven path of tramway development in England Appropriation of tramway and light rail technology Target Groups Researchers and students of transport studies, spatial planning, and geography Experts of local transport planning authorities, public transport companies
