The book presents the proceedings of the 30th Biennial Symposium on Communications 2021 (BSC21), a prestigious international research conference in communications, information theory, and signal processing. Started in 1962 by Queen’s University, Canada, the Symposium is now presented by the Canadian Society of Information Theory. Its 30th edition was hosted virtually by The University of Saskatchewan and held in Saskatoon from June 28 to 30, 2021. Topics include Communication and Information Theory, Coding and Signal Processing for Communications, and Multiple Antenna Systems and Cooperative Communications.

Design Thinking, a method widely used in design business and management, has changed the landscape of contemporary design. Whereas in the past non-designers were called upon to serve as external consultants ad-hoc, in an effort to promote creativity and innovation most design teams now consist of a mix of designers and other professionals. The impact of this development on the design landscape in recent years is so far without thorough investigation and analysis of its various influences. This book comprises an edited collection of selected papers from the 13th Design Thinking Research Symposium (DTRS13) which offers an exploration of Design Thinking from theoretical, practical, and pedagogical perspectives as well as critical analysis of the design process. The book is arranged in five parts as follows: Part 1: Thinking about design Part 2: Design thinking in the studio Part 3: Design thinking in practice and professional training Part 4: Design teams of diverse backgrounds, Interdisciplinary projects Part 5: Design and nature; visual representation Providing a comprehensive source for new perspectives on design and Design Thinking, Expanding the Frontiers of Design is ideal for designers and design academics of all disciplines wishing to strengthen and innovate their practice, as well as industry leaders who seek to consolidate their business strategies and evolve their work.

The two-volume set LNCS 12794-12795 constitutes the refereed proceedings of the 9th International Conference on Culture and Computing, C&C 2021, which was held as part of HCI International 2021 and took place virtually during July 24-29, 2021. The total of 1276 papers and 241 posters included in the 39 HCII 2021 proceedings volumes was carefully reviewed and selected from 5222 submissions. The papers included in the HCII-C&C volume set were organized in topical sections as follows: Part I: ICT for cultural heritage; technology and art; visitors’ experiences in digital culture; Part II: Design thinking in cultural contexts; digital humanities, new media and culture; perspectives on cultural computing.

This edited volume presents selected works from the 20th Biennial Alta Argumentation Conference, sponsored by the National Communication Association and the American Forensics Association and held in 2017. The conference brought together scholars from Europe, Asia, and North America to engage in intensive conversations about how argument functions in our increasingly networked society. The essays discuss four aspects of networked argument. Some examine arguments occurring in online networks, seeking to both understand and respond more effectively to the acute changes underway in the information age. Others focus on offline networks to identify historical and contemporary resources available to advocates in the modern day. Still others discuss the value-added of including argumentation scholars on interdisciplinary research teams analyzing a diverse range of subjects, including science, education, health, law, economics, history, security, and media. Finally, the remainder network argumentation theories explore how the interactions between and among existing theories offer fruitful ground for new insights for the field of argumentation studies. The wide range of disciplinary backgrounds and methodological approaches employed in Networking Argument make this volume a unique compilation of perspectives for understanding urgent and sustaining issues facing our society.

Primary Mathematics: Integrating Theory with Practice is a comprehensive introduction to teaching mathematics in Australian primary schools. Closely aligned with the Australian Curriculum, it provides a thorough understanding of measurement, geometry, patterns and algebra, data and statistics, and chance and probability. The fourth edition provides support for educators in key aspects of teaching: planning, assessment, digital technologies, diversity in the classroom and integrating mathematics content with other learning areas. It also features a new chapter on the role of education support in the mathematics classroom. Each chapter has been thoroughly revised and is complemented by classroom snapshots demonstrating practical application of theories, activities to further understanding and reflection questions to guide learning. New in this edition are 'Concepts to consider', which provide a guided explanation and further discussion of key concepts to support pre- and in-service teachers' learning and teaching of the fundamentals of mathematics.

In virtually every country, the price of residential access to the telephone network is kept low and cross-subsidized by business services, long distance calling, and various other telephone services. This pricing practice is widely defended as necessary to promote "universal service," but Crandall and Waverman show that it has little effect on telephone subscriptions while it has major harmful effects on the value of all telephone service. The higher prices for long distance calls reduce calling, shift the burden of paying for the network to those whose social networks are widely dispersed. Therefore, many poor and rural households--the intended beneficiaries of the pricing strategy--are forced to pay far more for telephone service than they would if prices reflected the cost of service. Despite these burdens, Congress has extended the subsidies to advanced services for schools, libraries, and rural health facilities. Crandall and Waverman show that other regulated utilities are not burdened with similarly inefficient cross-subsidy schemes, yet universality of water, natural gas, and electricity service is achieved. As local telephone service competition develops in the wake of the 1996 Telecommunications Act, the universal-service subsidy system will have to change. Subsidies will have to be paid from taxes on telecom services and paid directly to carriers or subscribers. Crandall and Waverman show that an intrastate tax designed to pay for each state's subsidized subscriptions is far less costly to the economy than an interstate tax. Robert W. Crandall is a senior fellow in Economic Studies at the Brookings Institution. Leonard Waverman is a visiting professor at the London Business School, on leave from the University of Toronto. They are coauthors of Talk Is Cheap: The Promise of Regulatory Reform in North American Telecommunications (Brookings, 1995).
