Download or read book THE JUNGLE AS A COMMUNICATION NETWORK REVISED written by and published by . This book was released on 1965 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elementary arguments and a simple model are used to clarify the dominant features of radio transmission through jungles. Part I represents the jungle as a plane uniform slab of constant conductivity and permittivity. A critical frequency is defined; below this frequency the slab behaves like a conductor; above it, it behaves like a dielectric. From these two limiting cases an upper limit on attenuation, which holds independently of the operating frequency, is derived. The model is applied to Herbstreit's experiments in the Panama jungle. Reasonable assumptions regarding the dielectric constant and density of the jungle lead to values between .02 and .04 mhos/m for the conductivity of the vegetation, which corresponds quite well with that of moist earth. Part II discusses the applicability of the uniform dielectric model employed in Part I. Equivalent circuit concepts are used to analyze the jungle as a four-terminal network. The model of Part I is shown to be strictly applicable only to a uniform--or at least a symmetrical--jungle. The determination of the network parameters for the equivalent circuit representing the jungle is discussed. The relation between the complex propagation constant and the amplitude of the forward scattered field is given. The results of using the Born approximation, and a rough first correction to it, to solve the field problem are also stated.

Download or read book Industrial Networks and Cinemas of India written by Monika Mehta and published by Taylor & Francis. This book was released on 2020-12-13 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume points to the limits of models such as regional, national, and transnational, and develops ‘network’ as a conceptual category to study cinemas of India. Through grounded and interdisciplinary research, it shows how film industries located in disparate territories have not functioned as isolated units and draws attention to the industrial traffic – of filmic material, actors, performers, authors, technicians, genres, styles, sounds, expertise, languages, and capital, across trans-regional contexts -- since the inception of cinema. It excavates histories of film production, distribution and exhibition, and their connections beyond regional and national boundaries, and between places, industrial practices, and multiple media. The chapters in this volume address a range of themes such as transgressive female figures; networks of authors and technicians; trans-regional production links and changing technologies, and new media geographies. By tracking manifold changes in the contexts of transforming media, and inter-connections between diverse industrial nodal points, this book expands the critical vocabulary in media and production studies and foregrounds new methods for examining cinema. A generative account of industrial networks, this volume will be useful for scholars and researchers of film studies, cinema studies, media studies, production studies, media sociology, gender studies, South Asian studies, and cultural studies.

Available in PDF, EPUB and Kindle. Book excerpt: Recent technological advancements have made it possible to use moderated discussion threads on social media to provide citizens with a means of discussion concerning issues that involve them. With the renewed interest in devising new methods for public involvement, the use of such communication tools has caused some concern on how to properly apply them for strategic purposes. Using New Media for Citizen Engagement and Participation provides emerging research exploring the theoretical and practical aspects of how social media should be added to public-involvement activities such as citizen juries, public deliberation, and citizen panels. Readers will be offered insights into the critical design considerations for planning, carrying out, and assessing public-involvement initiatives. Featuring coverage on a broad range of topics such as citizen journalism, online activism, and public discourse, this book is ideally designed for corporate professionals, broadcasters, news writers, column editors, politicians, policy managers, government administrators, academicians, researchers, practitioners, and students in the fields of political science, communications, sociology, mass media and broadcasting, public administration, and community-service learning.

Download or read book The Politics of Transnational Television written by Austin Ogunsuyi and published by Universal-Publishers. This book was released on 2004-05-29 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The central focus of this study is to provide an improved basis for articulating the politics of transnational television and its potentials for improving relations among nations. In this context, the politics of transnational television means the decision-making process that determines the degree of freedom of the press tolerated by individual governments and how that could affect broadcasting mode and attitudes toward other nations.The motivation for this research stems from a conviction that the cultural imperialism perspective on the nature and modes of transnational television are erroneous and therefore susceptible to a wide and often misleading theoretical assumption, with wide ranged implications.In reevaluating the concept of cultural imperialism, some fundamental questions are raised to determine to what extent its arguments are true. Using the elite theory of power in various societies, aided by Johan Galtung's model of a global communication in four worlds, we see a pattern of global television that suggests a similar motivation underlying media ownership in all societies.We acknowledge, with the support of a literature review and other data sources, the existence of a global systemic order where technology rich nations dominate technology over poor nations. But there is also substantial evidence to prove some of the poorer nations exercise some degree of autonomy. This makes it more difficult to explain cultural imperialism simply as a relationship where developed and developing nations are arranged in dominant/subordinate or top/down order.Through a strategy of original intent, we are able to show the elite in various societies acquire television mainly to satisfy their political, economic, or social interest. Media attitudes, therefore, are largely the ideological expression of local elite who determines foreign policy.
Download or read book Working on Labor written by and published by BRILL. This book was released on 2012-08-09 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of seventeen essays takes its inspiration from the scholarly achievements of the Dutch historian Jan Lucassen. They reflect a central theme in his research: the history of labor. The essays deal with five major themes: the production of specific commodities or services (diamonds, indigo, cigarettes, mail delivery by road runners); occupational groups (informal street vendors, prostitutes, soldiers, white-collar workers in the Dutch East India Company, VOC); geographical and social mobility (career opportunities on non-Dutch officers in the VOC, immigration into early-modern Holland; the influence of migrants on labor productivity; income differentials as migration incentives); contexts of labor relations (late medieval labor laws, subsistence labor and female paid labor, Russian peasant-migrant laborers, diverging political trajectories of cane-sugar industries); and the origins of labor-history libraries and archives.
Download or read book Mission in Praise Word and Deed written by Edward L. Smither and published by William Carey Publishing. This book was released on 2023-09-26 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Listening to the Voices of Global Practitioners In Christian mission, we cross boundaries between the people of God and the not-yet people of God, declaring “[God’s] glory among the nations” (Ps 96:3). Mission begins and ends in worship. In mission, we proclaim the death, burial, and resurrection of Christ. We also care for the whole person. Thus, at its core, mission intertwines praise, word, and deed. This book represents the latest in missiological thinking. Though some contributors are scholars and even professors, most are field practitioners —evangelists, church planters, Bible translators, medical professionals, refugee workers, and community development specialists. Based on decades of faithful service, they report on what they have learned about mission. Mission in Praise, Word, and Deed addresses a wide range of critical concerns, such as informal theological education, Bible translation, business as mission, trauma care, and working on multicultural teams. As we ponder best mission practices, it’s wise to hear from global practitioners—those who have been at it for a long time. This book represents the diversity of the global church. They are men and women from Africa, Asia, Latin America, North America, and Europe who have served or presently serve in places across the world. These contributors share the conviction that the future of missions involves a growing global church and missionary workforce joining hands to complete the Great Commission amid severe opposition and disruption.
