How Spanish-language radio has influenced American and Latino discourse on key current affairs issues such as citizenship and immigration. Winner, Book of the Year presented by the American Association of Hispanics in Higher Education Honorable Mention for the 2015 Latino Studies Best Book presented by the Latin American Studies Association The last two decades have produced continued Latino population growth, and marked shifts in both communications and immigration policy. Since the 1990s, Spanish- language radio has dethroned English-language radio stations in major cities across the United States, taking over the number one spot in Los Angeles, Houston, Miami, and New York City. Investigating the cultural and political history of U.S. Spanish-language broadcasts throughout the twentieth century, Sounds of Belonging reveals how these changes have helped Spanish-language radio secure its dominance in the major U.S. radio markets. Bringing together theories on the immigration experience with sound and radio studies, Dolores Ines Casillas documents how Latinos form listening relationships with Spanish-language radio programming. Using a vast array of sources, from print culture and industry journals to sound archives of radio programming, she reflects on institutional growth, the evolution of programming genres, and reception by the radio industry and listeners to map the trajectory of Spanish-language radio, from its grassroots origins to the current corporate-sponsored business it has become. Casillas focuses on Latinos' use of Spanish-language radio to help navigate their immigrant experiences with U.S. institutions, for example in broadcasting discussions about immigration policies while providing anonymity for a legally vulnerable listenership. Sounds of Belonging proposes that debates of citizenship are not always formal personal appeals but a collective experience heard loudly through broadcast radio.

This book discusses the computational geometry, topology and physics of digital images and video frame sequences. This trio of computational approaches encompasses the study of shape complexes, optical vortex nerves and proximities embedded in triangulated video frames and single images, while computational geometry focuses on the geometric structures that infuse triangulated visual scenes. The book first addresses the topology of cellular complexes to provide a basis for an introductory study of the computational topology of visual scenes, exploring the fabric, shapes and structures typically found in visual scenes. The book then examines the inherent geometry and topology of visual scenes, and the fine structure of light and light caustics of visual scenes, which bring into play catastrophe theory and the appearance of light caustic folds and cusps. Following on from this, the book introduces optical vortex nerves in triangulated digital images. In this context, computational physics is synonymous with the study of the fine structure of light choreographed in video frames. This choreography appears as a sequence of snapshots of light reflected and refracted from surface shapes, providing a solid foundation for detecting, analyzing and classifying visual scene shapes.

In "A Digital Liberia, " Darren Wilkins, an accomplished ICT Professional with more than twelve years of experience in the field of ICT, describes the impact of information and communications technology on the future of Liberia. Emerging from a fourteen-year civil war and more than 150 years of underdevelopment, poverty, and illiteracy, Liberia is presently behind the curve with respect to modern and emerging technologies. Even so, "A Digital Liberia" addresses six critical sectors in which ICT can play an important role: education, government, finance, agriculture, security, and healthcare. Wilkins delineates technologies that will bring a shift in the paradigm in the Liberian society and identifies broadband through submarine fiber optic cables located in and around Africa, along with pointing out open source, green IT, cloud computing, and mobile technologies as those technologies that enable Liberia to enter the Digital Economy. "A Digital Liberia, " one of the most optimistic approaches to a developing country's technology, represents an unprecedented effort by an African-born author to outline plan for technological development in Liberia.

Wireless Sensor Networks (WSNs) and the Internet of Things are facing tremendous advances both in terms of energy-efficiency as well as in the number of available applications. Consequently, there are challenges that need to be tackled for the future generation of WSNs. After giving an overview of the WSN protocols and IEEE 802.15.4 standard, this book proposes IEEE 802.15.4 Medium Access Control (MAC) sub-layer performance enhancements by employing not only RTS/CTS combined with packet concatenation but also scheduled channel poling (MC-SCP). Results have shown that the use of the RTS/CTS mechanism improves channel efficiency by decreasing the deferral time before transmitting a data packet. Furthermore, the Sensor Block Acknowledgment MAC (SBACK-MAC) protocol enables more efficiency as it allows the aggregation of several acknowledgement responses in one special Block Acknowledgment (BACK) Response packet. The throughput and delay performance have been mathematically derived under both ideal conditions (a channel environment with no transmission errors) and non-ideal conditions (with transmission errors). Simulation results successfully validate the proposed analytical models. This research reveals the importance of an appropriate design for the MAC sub-layer protocol for the desired WSN application. Depending on the mission of the WSN application, different protocols are required. Therefore, the overall performance of a WSN application certainly depends on the development and application of suitable e.g., MAC, network layer protocols.

Special attention has been given to the development of the materials forming the perovskite solar cell and their effect on the device performance, in addition to the recent progress of this emerging technology. Moreover, light has been shed on the perovskite elaboration techniques, in addition to the several techniques proposed to improve both the efficiency and the stability of perovskite solar cells. Furthermore, special emphasis was given to the three types of tandem solar cells and their recent advances starting from Perovskite/perovskite tandem solar cells to Perovskite/ CIGS tandem cells to perovskite/ heterojunction silicon tandem solar cells. The latter constitute a promising solution to improve photovoltaic solar cells performance.
