Today, millions people use mobile devices like smartphones and tablet computers on a daily basis to communicate and obtain information. Further, due to recent technical advances in mobile technology, consumers can use these devices to carry out a broad range of activities that previously required a desktop or laptop computer including shopping, banking, and accessing government services. Given these trends, providing government information and services "anytime, anywhere, and on any device" has become increasingly important, particularly as some mobile users may not have any other means of online access. This book describes the demographics of mobile users and the factors that might be associated with the increased use of mobile devices; the devices individuals are using to access government services and the challenges people face; and the actions the federal government has taken to enhance access to government services via mobile devices. This book also examines a report on Congress Member adoption and use of two social networking services: Twitter and Facebook. The book analyses data on Member use of Twitter and Facebook collected by an academic institution in collaboration with the Congressional Research Service during a two-month period between August and October 2011 and the adoption of both platforms as of January 2012.

The rise of sophisticated mobile devices and high-speed wireless networks is transforming the Internet and how our society interacts with it. Americans are rapidly embracing mobile technologies and the opportunities they create. This book examines data from the 2012 Current Population Survey (CPS) describing Americans' use of computers and the Internet. Data from this survey depict the accelerating popularity of mobile phone-based Internet use across demographic groups. The book also reveals the explosion in mobile Internet use accompanied by narrowing but persistent disparities in computer ownership and Internet use overall. This book's insights will allow policymakers, in cooperation with private partners, to make decisions that will improve America's productivity, ingenuity, world competitiveness, and standard of living.

The secret history of the invention that changed everything and became the most profitable product in the world. Odds are that as you read this, an iPhone is within reach. But before Steve Jobs introduced us to 'the one device', as he called it, a mobile phone was merely what you used to make calls on the go. How did the iPhone transform our world and turn Apple into the most valuable company ever? Veteran technology journalist Brian Merchant reveals the inside story you won't hear from Cupertino - based on his exclusive interviews with the engineers, inventors and developers who guided every stage of the iPhone's creation. This deep dive takes you from inside 1 Infinite Loop to nineteenth-century France to WWII America, from the driest place on earth to a Kenyan pit of toxic e-waste, and even deep inside Shenzhen's notorious 'suicide factories'. It's a first-hand look at how the cutting-edge tech that makes the world work - touch screens, motion trackers and even AI - made its way into our pockets. The One Device is a road map for design and engineering genius, an anthropology of the modern age and an unprecedented view into one of the most secretive companies in history. This is the untold account, ten years in the making, of the device that changed everything.

"This book is a collection of articles, written by both academics and practitioners as an evidence base for citizen engagement through information and communication technologies (ICTs). In it, the authors ask: how do ICTs empower through participation, transparency and accountability? Specifically, the authors examine two principal questions: Are technologies an accelerator to closing the "accountability gap" - the space between the supply (governments, service providers) and demand (citizens, communities, civil society organizations or CSOs) that requires bridging for open and collaborative governance? And under what conditions does this occur? The introductory chapters lay the theoretical groundwork for understanding the potential of technologies to achieving intended goals. Chapter 1 takes us through the theoretical linkages between empowerment, participation, transparency and accountability. In Chapter 2, the authors devise an informational capability framework, relating human abilities and well-being to the use of ICTs. The chapters to follow highlight practical examples that operationalize ICT-led initiatives. Chapter 3 reviews a sample of projects targeting the goals of transparency and accountability in governance to make preliminary conclusions around what evidence exists to date, and where to go from here. In chapter 4, the author reviews the process of interactive community mapping (ICM) with examples that support general local development and others that mitigate natural disasters. Chapter 5 examines crowdsourcing in fragile states to track aid flows, report on incitement or organize grassroots movements. In chapter 6, the author reviews Check My School (CMS), a community monitoring project in the Philippines designed to track the provision of services in public schools. Chapter 7 introduces four key ICT-led, citizen-governance initiatives in primary health care in Karnataka, India. Chapter 8 analyzes the World Bank Institute's use of ICTs in expanding citizen project input to understand the extent to which technologies can either engender a new "feedback loop" or ameliorate a "broken loop." The authors' analysis of the evidence signals ICTs as an accelerator to closing the "accountability gap." In Chapter 9, the authors conclude with the Loch Ness model to illustrate how technologies contribute to shrinking the gap, why the gap remains open in many cases, and what can be done to help close it. This collection is a critical addition to existing literature on ICTs and citizen engagement for two main reasons: first, it is expansive, covering initiatives that leverage a wide range of technology tools, from mobile phone reporting to crowdsourcing to interactive mapping; second, it is the first of its kind to offer concrete recommendations on how to close feedback loops."
