The industrial nations of the world have become Information Societies. Advanced technologies have created a communication revolution, and the individual, through the advent of computers, has become an active participant in this process. The "human" aspect, therefore, is as important as technologically advanced media systems in understanding communication technology. The flagship book in the Series in Communication Technology & Society, Communication Technology introduces the history and uses of the new technologies and examines basic issues posed by interactive media in areas that affect intellectual, organization, and social life. Author and series co-editor Everett M. Rogers defines the field of communication technology with its major implications for researchers, students, and practitioners in an age of ever more advanced information exchange.
Today, the general public craves information on food and agriculture with an unprecedented passion. But the agricultural sector, unaccustomed to an interested and inquisitive society, has largely failed to respond to the public’s demands for information. Instead, corporations, time-pressed journalists, bloggers, media celebrities, film-makers, authors and concerned consumers jumped in to fill the void. Food is emotional, and these players - some well-intentioned and others not - got a lot of traction playing off consumer fears of the unknown. This critical and timely book explains how changing demographics, cultural shifts, technological advances and agriculture’s silence all combined to create the perfect storm – a great chasm between those who know, and those who don’t know, agriculture. The ramifications of a poorly-informed consumer base are now becoming clear in our policy debates and consumer-driven business decisions. There is a lot of common ground between the agricultural sector and their consumer base, but each group largely fails to appreciate it, and the consequences of such a divide grow increasingly dire. Drawing on a wide-range of expertise, from leading agricultural researchers to major agribusiness leaders to consumer advocates, Eise and Hodde lay out exactly why communication is so urgently critical to our modern-day agricultural system. They outline the major themes affecting agricultural communication – perception, emotion, technology, science - and what we can do now to improve the debate and safeguard our future food supply for generations to come.This book is suitable for those who study agriculture, environmental economics and mass media and communication.
This book provides an in-depth coverage of the most recent developments in the field of wireless underground communications, from both theoretical and practical perspectives. The authors identify technical challenges and discuss recent results related to improvements in wireless underground communications and soil sensing in Internet of Underground Things (IOUT). The book covers both existing network technologies and those currently in development in three major areas of SitS: wireless underground communications, subsurface sensing, and antennas in the soil medium. The authors explore novel applications of Internet of Underground Things in digital agriculture and autonomous irrigation management domains. The book is relevant to wireless researchers, academics, students, and decision agriculture professionals. The contents of the book are arranged in a comprehensive and easily accessible format. Focuses on fundamental issues of wireless underground communication and subsurface sensing; Includes advanced treatment of IOUT custom applications of variable-rate technologies in the field of decision agriculture, and covers protocol design and wireless underground channel modeling; Provides a detailed set of path loss, antenna, and wireless underground channel measurements in various novel Signals in the Soil (SitS) testbed settings.
Many books have covered the rapidly evolving fields of information and communication technology (ICT) and space technology separately. However, no single book has ever focused on how the integration of these two areas is creating a stronger platform for various scientific advancements—including some research work that cannot be performed on Earth. To fill the void, Information, Communication, and Space Technology provides a novel illustration of that connection. Dividing content into sections that cover ICT, existing and future space technologies, and satellites, the author demonstrates the individual and combined power of each of these parts of the overall system. He explores how the combination of concepts from each of these interrelated fields is creating massive potential for broader advances in areas such as robotics, communications, navigation, agriculture, health care, and nanotechnology. The book introduces particular potential innovations, including "rocket-less" spacecraft launches, and development of a global system to balance energy distribution by using satellites that would collect solar energy and transmit it via microwave beams to different locations around the world. Equally useful to students and professionals, this work is a culmination of the domestic and international experience that the author has acquired throughout more than three decades as an instructor and researcher. Emphasizing the strong need to incorporate ICT and space technology into the general university curriculum, the book starts with basic explanations of key concepts and theories, building toward more concrete, application-oriented examples that reveal the importance and impact of new technologies. This includes coverage of how satellites transfer voice, video, and other data across continents, as well as techniques used to obtain very-high-resolution images from space for use in agricultural and environmental sciences.This timely work employs a logical, practically structured approach that will help readers to better understand existing and emerging ICT and space technologies, including the most recent developments and achievements in the field.
