Описание: How do social scientists study the impact of social networking sites on racial identity formation? How has the Internet impacted the accumulation of social and cultural capital? By synthesizing insights across a variety of disciplines, this book builds an original theoretical perspective through which these and other questions about core social processes can be addressed. Three case studies of how African Americans use information and communication technologies (ICTs) are used to illustrate this theoretical perspective. They show how groups can leverage ICTs to overcome historical inequalities. The book argues that the lenses through which scholars and society’s leaders think about new technology place too much emphasis on the technological and economic aspects of ICTs, and not enough on the impact of ICTs on social processes at the everyday level.

Описание: Design of Digital Phase Shifters for Multipurpose Communication Systems covers a new emerging need in designing digital phase shifters for modern communication systems. With the advancement of new generation mobile communication systems, directed beams save a substantial amount of RF-power, and improve the noise immunity. In this regard, beam-forming circuits, namely, digital phase shifters constitute essential parts of the antenna arrays. Therefore, this book is devoted to design of digital phase shifters for various communications systems. In the good old days, phase shifter design requirements used to demand narrow bandwidth with no physical size constraints. Nowadays, they must be compact and suitable for Very Large Scale Integrated Circuits (VLSI) or Microwave Monolithic Integrated Circuit (MMIC) implementation with Wide Phase Range (WPR) and Wide Frequency Band (WFB). Since the 1980s, the author has been designing digital phase shifters for various applications. He started to work with loaded lines phase shifters, and then employed branch line couplers to achieve wider frequency bands. In order to reduce the physical size, he used a 3 element Symmetric LC ladder based T or PI configurations. In order to achieve broad frequency band with large phase range, usage of LC lattice structures is inevitable. Lately, the author designed phase shifters using both lowpass and highpass LC ladder and lattice based switched-structures, which are suitable for monolithic implementation. In the course of design, MOS transistors were employed as switching elements. This book includes several novel digital phase shifter topologies, which provides wide phase range and wideband operation. Technical topics discussed in the book include:
Basic Concept of Antenna Arrays
Concept of Digital Phase Bit
Scattering Parameters to analyze the electric performance of phase shifters
Transmission Lines as circuit elements to construct practical phase shifters
Loaded Line Digital Phase Shifters (DPS)
Lowpass Based T/PI Section DPS
Highpass Based T/PI Section DPS
3-Element LC T/PI Section DPS
Wide Phase Range, Wide Frequency Band Symmetric Lattice Based DPS
For each topology presented, explicit design equations are provided and programs to assess the electric performance of each topology is developed in a MatLab environment. It is expected that the reader will be self-sufficient to design and implement the digital phase shifters topologies presented in this book.
This volume reflects the discussion that emerged around the controversial concepts «communication form», «communicative practice», «medium» and «genre». It provides a comprehensive overview of the history and current state-of-affairs of these concepts, and combines theoretical contributions from various perspectives with thorough empirical studies of current communication forms, media, and practices. The contributions deal with fields ranging from public signage in cities, video games and self-tracking to historical accounts of changing communicative potentials and practices concerning the «National Geographic Magazine» and the personal blog. Due to its interdisciplinary character, the volume points out various new directions for future research.

Описание: The post-digital publishing paradigm offers authors, readers, publishers and scholars the opportunity to engage with the production and circulation of the book (in all its forms) beyond the conventional boundaries and binaries of the pre-digital and digital eras. Post-Digital Book Cultures: Australian Perspectives is a collection of scholarly writing that examines these opportunities, from a range of disciplinary and methodological approaches, with the aim of engaging with the questions that define post-digital book cultures beyond the role of e-books. Examinations of digital publishing in the literary field can often be characterised as either narratives of decline or narratives of revolution. As we move into the third decade of the twenty-first century, what has become clear is that neither of these approaches accurately encapsulate the role of the digital on contemporary publishing practice. Rather than upending book publishing culture, the emergence of digital technologies and platforms in the field has complicated and recontextualised the production, circulation and consumption of books. This collection of essays brings together contributions from scholars and industry practitioners to consider the changing nature of the production of the book and the circulation of book culture within a post-digital context and platform enclosures.
Описание: This book shares new research findings and practical lessons learned that will foster advances in digital design, communication design, web, multimedia and motion design, graphic design and branding, and other related areas.
This bestselling text pioneered the comparison of qualitative, quantitative, and mixed methods research design. For all three approaches, John W. Creswell and new co-author J. David Creswell include a preliminary consideration of philosophical assumptions; key elements of the research process; a review of the literature; an assessment of the use of theory in research applications, and reflections about the importance of writing and ethics in scholarly inquiry.
