El tiempo detenido y otras historias de África
by Lola HierroPrólogo de Xavier AldekoaEpílogo de José Naranjo Una mirada fascinante al continente africano para descubrir vidas, culturas, tradiciones, sabores y olores, que invitan al lector a inventar su propia África. Gracias a su trabajo como reportera, Lola Hierro ha conocido la esperanza de igualdad de las mujeres en Etiopía; ha dormido junto a hipopótamos en Kenia; ha admirado el trabajo de las campesinas del mar en Tanzania; ha saboreado el café preparado a la manera tradicional en Uganda; ha sido alumna de la maestra Doussou Fané en Malí; ha sido testigo de las duras condiciones de vida de los refugiados en Níger; ha comprobado la resistencia de los bosquimanos en Botsuana; ha abrazado el mar y el desierto en Namibia, y ha sobrevivido a las indómitas aguas del río Zambeze en Zimbaue. Una invitación a viajar en un matatu particular y observar la forma de vida y los cambios que se producen en un vastísimo territorio en el que, en palabras de la autora, «el tiempo se detiene ante nuestros ojos, sí, pero como la noria que para un momento y permite que nos subamos antes de empezar a girar y llevarnos al cielo».
El tiempo por cárcel: Conversaciones con Juan Esteban Constain
by Roberto PomboRoberto Pombo, director de El Tiempo conversa con Juan Esteban Constaín. "La voz de este libro, recogida en horas y horas y horas de grabaciones al final de la tarde, es la de un periodista que ha ejercido su profesión desde la reportería judicial hasta la dirección del periódico de mayor circulación en el país. Con una visión de las cosas que está aquí presente y que es inequívoca; con una concepción del mundo y del oficio que él mismo explica sin reservas ni complejos. ¿Que hay quienes no la comparten? Ojalá, está bien. Pero este libro no es una apología niuna biografía -cómo podría serlo- sino un diálogo: una invitación a hablar sobre el pasado, el presente y el futuro, sobre todo; un recuento a veces doloroso y a veces cómico de lo que puede ocurrir en una vida que se ha pasado de alguna manera contando la vida de los otros. Mi voz aquí es apenas la de un interlocutor: una voz que escucha, que busca saber un poco más. Una voz que no juzga los aciertos ni los errores de nadie; quizás apenas una voz que atiza las palabras y que va destejiendo el hilo del relato. Porque quién no tiene el tiempo por cárcel".Juan Esteban Constaín
El vendedor de silencio
by Enrique Serna«No pedía mucho, carajo, sólo que lo dejaran prostituirse a su modo.» A mediados del siglo XX, Carlos Denegri era el líder de opinión más influyente de México. Reportero estrella del diario Excélsior, tenía una red de contactos internacionales envidiada por todos los periodistas. Mimado por el poder, como columnista político sobresalió por su falta de escrúpulos, al grado de que Julio Scherer lo llamó "el mejor y el más vil de los reporteros". Industrializó el "chayote" cuando esa palabra todavía no se usaba en la jerga política. En su Fichero Político, donde fungía como vocero extraoficial de la Presidencia y cobraba todas las menciones, podía difamar a cualquiera con impunidad absoluta. Según Carlos Monsiváis, un coscorrón en esa columna representaba "una temporada en el infierno" para cualquier aspirante a un cargo público. Aunque ganaba millones por publicar alabanzas, se hizo más rico aúnpor medio de la extorsión, callándose lo que sabía de sus poderosos clientes. La personalidad pública de Carlos Denegri es indisociable de las atroces vejaciones misóginas que cometió en su vida privada. Era tan prepotente y déspota en el trato con las mujeres como en el periodismo, de modo que su patología fue a la vez íntima y social. Radiografía del machismo a la mexicana y epitafio de la dictadura perfecta, esta novela es un estudio de carácter incisivo y mordaz, sustentado en un arduo trabajo de investigación, que por momentos linda con la farsa trágica. Enrique Serna vuelve a una de sus vetas narrativas predilectas, la reconstrucción del pasado, para entregarnos un fresco histórico apasionante. La crítica ha dicho: «El arte de Serna consiste en una serie de procedimientos encaminados a hacernos más persuasiva la ilusión realista -esa que sólo puede darse en la mejor literatura-, a comunicar al lector la sensación de estar directamente enfrentado con la vida.» Ignacio Solares «En sus novelas y cuentos descubrimos un arte consumado de la sorpresa, una ferocidad no exenta de gracia y un sentido del sarcasmo que nunca se rebaja a la mera caricatura.» Claude Fell «Quien se acerca a las narraciones de Enrique Serna ríe mucho durante la lectura y al llegar al punto final un ligero malestar lo hace quedarse un tiempo pensativo, como si se reconociera de pronto en el patetismo de los personajes.» Eduardo Antonio Parra «Reconozco en Serna el entendimiento profundo, casi quisquilloso, que consiste en poner el archivo al servicio de la ficción y no ejercer ni de amanuense erudito ni de mero coleccionista de avisos y extravagancias.» Christopher Domínguez

El último que apague la luz: Sobre la extinción del periodismo
by Lluís BassetPresenciamos la decadencia de la prensa escrita y de la cultura tal como la conocemos, y los periodistas tienen la última palabra. El periódico impreso va a desaparecer. Y lo hará pronto, antes de lo que creíamos. Con él van a desvanecerse o transformarse muchas otras cosas. El periódico ha sido durante una larga época la imagen del mundo y su conciencia, la escenificación diaria de la idea de una realidad ordenada y jerarquizada, y un formidable instrumento frente a cualquier poder. Pero los medios cambian porque los ciudadanos que los consumen y usan quieren que cambien. Son los lectores los que están protagonizando el salto a esta nueva era. Este no es, por tanto, únicamente un libro para periodistas, ni un ensayo sobre la crisis de un gremio. La desaparición del periódico impreso dejará un vacío real, no solo en la vida cotidiana sino también en el funcionamiento de nuestras sociedades. Ha llegado el momento de imaginar el nuevo tiempo, de pensar cómo serán la realidad y la historia sin periódicos, cómo se organizarán la libertad y la democracia sin ese pliego de papel que cada mañana llega simultáneamente a las manos de centenares de miles de personas. Con realismo y precisión, respaldado por el bagaje de cuarenta años de experiencia en la primera línea del periodismo y una mirada lúcida y valiente, Lluís Bassets escribe la crónica de los últimos días de la prensa escrita. ¿El estallido de la «burbuja periodística» será también la definitiva señal del fin de la cultura y la democracia tal y como las conocemos? ¿Hacia dónde nos lleva la «efervescencia digital»? Reseñas:«Lluís Bassets mete el dedo en todas las heridas que afectan al periodismo que se ha hecho y que se está haciendo. Ni la prensa tradicional fue el espejo de todas las virtudes, ni la marea digital está por entero contaminada de detritus. O viceversa.»José Andrés Rojo, El País «Escrito con el aire y el ritmo con que Bassets ejerce la literatura de su periodismo, es una obra que te sobrecoge como ciudadano y que te golpea como periodista.»Juan Cruz «El último que apague la luz, que es lectura de emergencia para los miembros de un gremio aún atrincherados en redacciones que nunca volverán a ser lo que eran ##todo deberá ser más modesto##, es, además, una invitación inteligente para reflexionar sobre cuál ha sido y será el papel social del periodismo. Y eso trasciende el estricto interés profesional en tanto que la vigilancia de los poderes que presupone la elaboración rigurosa de las noticias es un ingrediente fundamental para el buen funcionamiento de una democracia.»Jordi Amat, Suma cultural
Electable: Why America Hasn't Put a Woman in the White House . . . Yet
by Ali VitaliA fearless deep dive into the 2020 election from former MSNBC “Road Warrior” and now NBC Capitol Hill correspondent Ali Vitali, who covered the campaign trail every step of the way—investigating the gendered double standards placed on women presidential candidates of that cycle and those who came before, and what it will take for a woman to finally break the glass ceiling and win the White House.Opening with the moment when Joe Biden and Kamala Harris were finally declared the winners of the 2020 race—the long, drawn-out journey towards who would next inhabit the White House, and the resulting and disputed defeat of Donald Trump, Electable is a sweeping look at a lingering question from that Presidential race. Why, when we saw more women run for President of the United States than ever before in our history, did we still not cross that final hurdle? Following the 2020 race minute by minute as the reporter embedded with Elizabeth Warren, Ali Vitali witnessed up-close the way that our most recent election was unique—not simply for the way in which the incumbent conducted himself, but for the ways in which the field, rich with Democrats from all kinds of backgrounds, was both modern but also more of the same. With more female candidates than ever before, this was a history-making race, and yet these women—most of them incredibly qualified with decades of public service on their resumes—dealt once again with a different level of scrutiny than their male counterparts. Woven throughout is close examination of the treatment of Hillary Clinton, Geraldine Ferraro, Shirley Chisholm, and those on the right as well. Grappling with ideas around the “likeability” and “electability” issues, as well as fundraising hurdles many female candidates face, Vitali asks the same questions she and so many have been grappling with for decades, but especially since Hillary Clinton’s devastating defeat in 2016: Why is it so hard for a woman to be taken seriously as a presidential contender? What will it take for men and women to be held to the same standard? What happens next?Electable tackles these questions, with specific, behind-the-scenes, play-by-play detail.Gabbard, Harris, Williamson, Gillibrand, Warren, Klobuchar…and then there were none.
Election Politics and the Mass Press in Long Edwardian Britain (Routledge Focus on Journalism Studies)
by Christopher Shoop-WorrallThis book explores the ways in which the emergence of the ‘new’ daily mass press of the late-nineteenth and early-twentieth centuries represented a hugely significant period in histories of both the British press and the British political system. Drawing on a parallel analysis of election-time newspaper content and archived political correspondence, the author argues that the ‘new dailies’ were a welcome and vibrant addition to the mass political culture that existed in Britain prior to World War One. Chapters explore the ways in which the three ‘new dailies’ – Mail, Express, and Mirror – represented political news during the four general elections of the period; how their content intersected with, and became a part of, the mass consumer culture of pre-Great War Britain; and the differing ways political parties reacted to this new press, and what those reactions said about broader political attitudes towards the worth of ‘mass’ political communication. This book will be of interest to students and scholars of media history, British popular politics, journalism history, and media studies.

Elections and TV News in South Africa: Desperately Seeking Depth
by Bernadine JonesThis book takes television news seriously. Over the course of nine chapters, Elections and TV News in South Africa shows how six democratic South African general elections, 1994–2019, were represented on both local and international news broadcasts. It reveals the shifting narratives about South African democracy, coupled with changing and challenging political journalism practices. The book is organised in three parts: the first contains a history of South African democracy and an overview of the South African media environment. The second part is a visual analysis of the South African elections on television news, exploring portrayals of violence, security, power, and populism, and how these fit into normative news values and the ruling party’s tightening grip on the media. The final part is a conclusion, a call to action, and a suggestion to improve political journalistic practice.
Electoral Campaigns, Media, and the New World of Digital Politics
by Richard Davis David TarasToday, political leaders and candidates for office must campaign in a multimedia world through traditional forums—newspapers, radio, and television—as well as new digital media, particularly social media. Electoral Campaigns, Media, and the New World of Digital Politics chronicles how Twitter, Facebook, Reddit, email, and memes are used successfully and unsuccessfully to influence elections. Each of these platforms have different affordances and reach various audiences in different ways. Campaigns often have to wage different campaigns on each of these mediums. In some instances, they are crucial in altering coverage in the mainstream media. In others, digital media remains underutilized and undeveloped. As has always been the case in politics, outcomes that depend on economic and social conditions often dictate people’s readiness for certain messages. However, the method and content of those messages has changed with great consequences for the health and future of democracy. This book answers several questions: How do candidates/parties reach audiences that are preoccupied, inattentive, amorphous, and bombarded with so many other messages? How do they cope with the speed of media reporting in a continuous news cycle that demands instantaneous responses? How has media fragmentation altered the campaign styles and content of campaign communication, and general campaign discourse? Finally and most critically, what does this mean for how democracies function?
Electoral Politics in Sri Lanka: Presidential Elections, Manipulation and Democracy (Europa Country Perspectives)
by S. I. KeethaponcalanThis volume examines and analyses electoral politics in Sri Lanka through the theoretical framework of manipulation. The following questions guided the study: how do political actors manipulate elections, and what are the salient features of electoral politics in Sri Lanka? Primary and secondary data formed the basis of the analysis, examining eight presidential elections. The research findings indicated that Sri Lankan governments, political parties and political leaders have taken advantage of six types of electoral manipulation, including constitutional tinkering, field fixing, time fixing, vote suppression, process manipulation and resource manipulation. Through a close examination of eight presidential elections, research carried out for the volume found that elections are often associated with violence; presidential elections are mainly a majoritarian affair in which minority communities play only a marginal role; there is a significant gender imbalance, as women’s participation in the electoral process is very limited; despite the presence of a large number of candidates contesting the election, it always remains a two-way race; and amid extensive manipulation and other problems, voter participation tends to be high. This volume will be a valuable resource for students, academics and researchers who focus on democracy, good governance, electoral studies and South Asian politics and history, and will enhance the conceptual foundation of democracy advocates and activists.
Electrical Systems 2: From Diagnosis to Prognosis
by Hubert Razik Abdenour SoualhiMethods of diagnosis and prognosis play a key role in the reliability and safety of industrial systems. Failure diagnosis requires the use of suitable sensors, which provide signals that are processed to monitor features (health indicators) for defects. These features are required to distinguish between operating states, in order to inform the operator of the severity level, or even the type, of a failure. Prognosis is defined as the estimation of a system's lifespan, including how long remains and how long has passed. It also encompasses the prediction of impending failures. This is a challenge that many researchers are currently trying to address. Electrical Systems, a book in two volumes, informs readers of the theoretical solutions to this problem, and the results obtained in several laboratories in France, Spain and further afield. To this end, many researchers from the scientific community have contributed to this book to share their research results.

Electromagnetic Fields, Environment and Health
by Anne Perrin Martine SouquesA good number of misconceptions are currently circulating on the effects of non-ionizing radiations on our health, which can lead to an oversimplification of the issue, to potentially dangerous assumptions or to misleading data analysis. Health effects may be exaggerated, or on the contrary underplayed. The authors of this work (doctors, engineers and researchers) have endeavored to supply validated and easily understandable scientific information on the electromagnetic fields and their biological and health effects. After a general review of the physics of the waves and a presentation of non-ionizing radiations, the authors review the main emission sources encountered in our daily environment. They summarize simply but as accurately as possible the current knowledge on their biological effects. The safety limits recommended by international organizations are presented for the different frequency ranges. This book is intended for doctors, teachers, scientists, students, policy makers and anyone else interested in a deeper understanding of the health effects of electromagnetic fields. Intended to serve a broad readership, everyone will approach it according to their respective level of curiosity and knowledge. It is neither an exhaustive inventory of all the studies made to date, nor a survey text focusing only on some chosen studies. Nor is the objective to present all the sources of non-ionizing radiations. Interested readers will be given the opportunity to broaden their knowledge, also by consulting the selected bibliography presented by the authors at the end of each chapter.
Electromagnetic Performance Analysis of Graded Dielectric Inhomogeneous Radomes (SpringerBriefs in Applied Sciences and Technology)
by Raveendranath U. Nair P. Mahima M. Suprava S. Vandana Mohammed P.S. YazeenThis book reports on a new radome wall configuration based on an inhomogeneous planar layer, which overcomes current fabrication constraints in radome design and yields improved electromagnetic (EM) characteristics. The book also includes a detailed description of radomes and antenna-radome interaction studies for different radome wall configurations. The radome wall was designed using the equivalent transmission line method (EQTLM), since it requires less computational speed and provides accurate results. In order to substantiate the accuracy of the results obtained using EQTLM, the simulated results based on full wave methods like CST Microwave Studio Suite are also included. The EM performance analysis of the antenna-radome system for two radome shapes, tangent ogive (for airborne applications) and hemispherical (for ground-based applications), was performed using Geometric Optics Method in conjunction with the Aperture Integration Method. To show the efficacy of the new design, a comparison of performance characteristics between the novel radome and conventional wall configurations is also included. Lastly, it presents antenna-radome interaction studies for various aperture distributions. The book offers a unique resource for all researchers working in the area of microwave radomes.

Electromagnetic Waves and Optics: A Linear Systems Approach
by Navin KhanejaThe book explores electromagnetic (EM) waves, which are present everywhere—from radio, television, and cell phones to satellite dishes, antennas, and WiFi. The propagation of EM waves is governed by Maxwell's equations. When these waves pass through a medium, they slow down and refract, while in a metallic medium, they are reflected. Metallic boxes and pipes can store and direct EM waves, known as cavities and waveguides. Oscillating currents generate and transmit EM waves through antennas, allowing for long-distance communication after the waves propagate. Since oscillating currents emit EM waves, the author uses coaxial cables and transmission lines to reduce radiation and carry high-frequency currents efficiently. EM waves at very high frequencies in the optical range are responsible for transmitting visual information. The author also discusses lenses and optical instruments like telescopes and microscopes, which are used to magnify optical signals. Additionally, the quantum mechanical origins of a material’s permittivity, which affects the speed of light through the medium, are examined.

Electromechanical Transmitters for ELF/VLF Radio (Synthesis Lectures on Engineering, Science, and Technology)
by Jarred S. Glickstein Soumyajit MandalThis book describes a new, extremely low frequency (ELF)/ very low frequency (VLF) miniaturized transmitter concept, based on the mechanical motion of permanent magnets or electrets. The authors explain how utilizing the very high energy density of modern ferromagnetic and ferroelectric materials, such “electromechanical transmitters’’ can provide much higher field generation efficiency than conventional antennas, thus enabling practical ELF/VLF wireless communications links. The text begins with the fundamental challenges of such links and provides an historical overview of the attempts that have been made to address these challenges. It then focuses on the design and implementation of practical electromechanical ELF/VLF transmitters, which is an interdisciplinary subject that spans multiple research areas including electromagnetics, power electronics, control systems, and mechanical design. The authors also describe how such transmitters can be combined with receivers and signal processing algorithms to realize complete ELF/VLF links in challenging environments.
Electronic Communications for Technicians
by Tom WheelerWritten by a technician for technicians, this book fills the gap between communications books that are either highly mathematical (suitable for engineers) or technically weak (not enough detail for technical learners).
