Emissions from mobile sources contribute significantly to air pollution in the United States. Such sources include cars and light- and heavy-duty trucks; diesel-powered cranes, bulldozers, and tractors; and equipment such as lawnmowers that run on small gasoline engines. The role of state versus federal government in establishing mobile-source emissions standards is an important environmental management issue. With this in mind, Congress called on EPA to arrange an independent study of the practices and procedures by which California develops separate emissions standards from the federal government and other states choose to adopt the California standards. The report provides an assessment of the scientific and technical procedures used by states to develop or adopt different emissions standards and a comparison of those policies and practices with those used by EPA. It also considers the impacts of state emissions standards on various factors including compliance costs and emissions. The report concludes that, despite the substantial progress in reducing emissions from mobile sources nationwide, more needs to be done to attain federal air-quality standards in many parts of the country. Additionally, California should continue its pioneering role in setting emissions standards for cars, trucks, and off-road equipment.

Cloud Computing wird von nahezu allen fuhrenden Analysten als einer der Top-5-IT-Trends gesehen, der gegenwartig aus der Hype-Phase in den Status der praktischen betrieblichen Umsetzung ubergeht. Inzwischen wird nicht mehr diskutiert, ob Cloud Computing uberhaupt eine praktikable Moeglichkeit des IT-Sourcing ist, sondern vielmehr, wie diese Moeglichkeit sich sicher und mit hohem Nutzen fur Firmen einsetzen lasst. Es wird aufgezeigt, wo die Vorteile aber auch die Stolpersteine liegen und welche prinzipiellen Loesungen es gibt, um die Chancen zu realisieren und Risiken moeglichst zu umgehen.
The implementation of near-field communication (NFC) technology in smartphones has grown rapidly, especially due to the use of this technology as a payment system. In addition, the ability to use the energy transmitted not only for communication, but also for feeding other devices, which together with the low cost of NFC chips and the internet connectivity of the smartphones, allows the design of battery-less RF tags with sensing capabilities, whose information can be sent to the cloud. This is of great interest in the increasing amount of IoT (Internet of Things) scenarios. This book studies the feasibility of these sensors, analyzing the different parameters that have an influence on performance and in the range of operation. It also presents techniques to increase the range and analyzes the effects of certain materials when they are close to the antenna. The design and analysis of several sensors that can be powered and read by any NFC enabled device are presented in this work.
"The world is going mobile at an astounding pace. Estimates show 80 percent of global Internet access will take place through mobile devices by 2016. Smartphones, tablets, and handheld devices have reshaped communications, the global economy, and the very way in which we live. The revolution is an electronic nirvana: for the first time in human history we have sophisticated digital applications to help us learn, access financial and health care records, connect with others, and build businesses. But the one trillion dollar mobile industry is still relatively young. Leaders in both the public and private sectors need to figure out how to apply mobile technologies or mobile devices to optimize education, health care, public safety, disaster preparedness, and economic development. And the ever-expanding mobile frontier presents new challenges to law, policy, and regulations and introduces new tensions; one person's idea of cautious deliberation can be another's idea of a barrier to innovation. In Going Mobile, Darrell M. West breaks down the mobile revolution and shows how to maximize its overall benefits in both developed and emerging markets. Contents 1. The Emergence of Mobile Technology 2. Driving Global Entrepreneurship 3. Alleviating Poverty 4. Invention and the Mobile Economy 5. Mobile Learning 6. Improving Health Care 7. Medical Devices and Sensors 8. Shaping Campaigns and Public Outreach 9. Disaster Relief and Public Safety 10. Looking Ahead "
The Federal Trade Commission (FTC) has worked on privacy issues for over forty years, and in 2000 began considering the privacy implications raised by consumers' growing use of mobile devices. More recently, the FTC hosted a mobile privacy panel discussion that focused on transparency. With so many players collecting and using consumer data, who should provide privacy information to consumers? Given the limited screen space of mobile devices, how can this information be conveyed? This book explores and offers suggestions for the major participants in the mobile ecosystem as they work to improve mobile privacy disclosures.

Offering a deeper understanding of today’s internet media and the management theory behind it Platforms are everywhere. From social media to chat, streaming, credit cards, and even bookstores, it seems like almost everything can be described as a platform. In The Platform Economy, Marc Steinberg argues that the “platformization” of capitalism has transformed everything, and it is imperative that we have a historically precise, robust understanding of this widespread concept. Taking Japan as the key site for global platformization, Steinberg delves into that nation’s unique technological and managerial trajectory, in the process systematically examining every facet of the elusive word platform. Among the untold stories revealed here is that of the 1999 iPhone precursor, the i-mode: the world’s first widespread mobile internet platform, which became a blueprint for Apple and Google’s later dominance of the mobile market. Steinberg also charts the rise of social gaming giants GREE and Mobage, chat tools KakaoTalk, WeChat, and LINE, and video streaming site Niconico Video, as well as the development of platform theory in Japan, as part of a wider transformation of managerial theory to account for platforms as mediators of cultural life. Analyzing platforms’ immense impact on contemporary media such as video streaming, music, and gaming, The Platform Economy fills in neglected parts of the platform story. In narrating the rise and fall of Japanese platforms, and the enduring legacy of Japanese platform theory, this book sheds light on contemporary tech titans like Facebook, Google, Apple, and Netflix, and their platform-mediated transformation of contemporary life—it is essential reading for anyone wanting to understand what capitalism is today and where it is headed.
The message of this book is simple: the mobile phone strengthens social bonds among family and friends. With a traditional land-line telephone, we place calls to a location and ask hopefully if someone is "there"; with a mobile phone, we have instant and perpetual access to friends and family regardless of where they are. But when we are engaged in these intimate conversations with absent friends, what happens to our relationship with the people who are actually in the same room with us? In New Tech, New Ties, Rich Ling examines how the mobile telephone affects both kinds of interactions--those mediated by mobile communication and those that are face to face. Ling finds that through the use of various social rituals the mobile telephone strengthens social ties within the circle of friends and family--sometimes at the expense of interaction with those who are physically present--and creates what he calls "bounded solidarity." Ling argues that mobile communication helps to engender and develop social cohesion within the family and the peer group. Drawing on the work of Emile Durkheim, Erving Goffman, and Randall Collins, Ling shows that ritual interaction is a catalyst for the development of social bonding. From this perspective, he examines how mobile communication affects face-to-face ritual situations and how ritual is used in interaction mediated by mobile communication. He looks at the evidence, including interviews and observations from around the world, that documents the effect of mobile communication on social bonding and also examines some of the other possibly problematic issues raised by tighter social cohesion in small groups.Rich Ling is Senior Researcher at the Norwegian telecommunications company Telenor and Adjunct Research Scientist at the University of Michigan. He is the author of The Mobile Connection: The Cell Phone's Impact on Society.
