Giving Bodies Back to Data: Image Makers, Bricolage, and Reinvention in Magnetic Resonance Technology (Leonardo)
by Silvia CasiniAn examination of the bodily, situated aspects of data-visualization work, looking at visualization practices around the development of MRI technology.Our bodies are scanned, probed, imaged, sampled, and transformed into data by clinicians and technologists. In this book, Silvia Casini reveals the affective relations and materiality that turn data into image--and in so doing, gives bodies back to data. Opening the black box of MRI technology, Casini examines the bodily, situated aspects of visualization practices around the development of this technology. Reframing existing narratives of biomedical innovation, she emphasizes the important but often overlooked roles played by aesthetics, affectivity, and craft practice in medical visualization. Combining history, theory, laboratory ethnography, archival research, and collaborative art-science, Casini retrieves the multiple presences and agencies of bodies in data visualization, mapping the traces of scientists' body work and embodied imagination. She presents an in-depth ethnographic study of MRI development at the University of Aberdeen's biomedical physics laboratory, from the construction of the first whole-body scanner for clinical purposes through the evolution of the FFC-MRI. Going beyond her original focus on MRI, she analyzes a selection of neuroscience- or biomedicine-inspired interventions by artists in media ranging from sculpture to virtual reality. Finally, she presents a methodology for designing and carrying out small-scale art-science projects, describing a collaboration that she herself arranged, highlighting the relational and aesthetic-laden character of data that are the product of craftsmanship and affective labor at the laboratory bench.

The Glare
by Margot HarrisonAfter living off the grid for more than a decade, a teenage girl must play a dangerous game -- and face the shadows of her past -- to save the world from a dangerous dark force. <P><P>After ten years of living on an isolated, tech-free ranch with her mother, sixteen-year-old Hedda is going back to the world of the Glare -- her word for cell phones, computers, and tablets. Hedda was taught to be afraid of technology, afraid that it would get inside her mind and hurt her. But now she's going to stay with her dad in California, where she was born, and she's finally ready to be normal. She's not going to go "off-kilter," like her mom says she did when she was just a little kid. <P><P>Once she arrives, Hedda finally feels like she's in control. She reunites with old friends and connects with her stepmom and half-brother. Never mind the terrifying nightmares and visions that start trickling back -- they're not real.Then Hedda rediscovers the Glare: the real Glare, a first-person shooter game from the dark web that scared her when she was younger. They say if you die thirteen times on level thirteen, you die in real life. But as Hedda starts playing the so-called "death game" -- and the game begins spreading among her friends -- she realizes the truth behind her nightmares is even more twisted than she could have imagined. And in order to stop the Glare, she'll have to first confront the darkness within herself.
Glaser on Health Care IT: Perspectives from the Decade that Defined Health Care Information Technology (HIMSS Book Series)

He has written a regular column for Hospitals & Health Networks in which he comments on a wide range of topics, including improving organizational performance through health information technology (HIT), changes in HIT architecture, challenges in leveraging data, and the evolution of the role of IT leadership. Glaser on Health Care IT: Perspectives from the Decade that Defined Health Care Information Technology is a collection of some of the most widely read articles that have been published in H&HN Daily, H&HN Weekly, and Most Wired Online in the past decade (2005–2015). The columns are dated to show their original publication dates, and the material is organized into four broad themes: HIT Applications and Analytics Challenges Improving Organizational Performance through HIT IT Management Challenges HIT Industry Observations Each section offers readers an intimate look at the myriad issues associated with getting IT "right" and the organizational performance gains that can be achieved in doing so. Moreover, the book examines the power and potential of the technologies available to health care providers today, as well as the transformative nature of those we have yet to fully embrace.From seasoned CIOs and consultants to software developers and nurses, this book provides invaluable insights and guidance to all those seeking to make the delivery of care safer, more effective, and more efficient through the application of health care IT.Foreword by Russ Branzell, President and CEO, College of Healthcare Information Management Executives (CHIME) Co-published with Health Forum, Inc.
Glass Houses
by Joel BrennerA chilling and revelatory appraisal of the new faces of espionage and warfare on the digital battleground Shortly after 9/11, Joel Brenner entered the inner sanctum of American espionage, first as the inspector general of the National Security Agency, then as the head of counterintelligence for the director of National Intelligence. He saw at close range the battleground on which adversaries are attacking us: cyberspace. Like the rest of us, governments and corporations inhabit "glass houses,” all but transparent to a new generation of spies who operate remotely from such places as China, the Middle East, Russia, and even France. In this urgent wake-up call, Brenner draws on his extraordinary background to show what we can-and cannot-do to prevent cyber spies and hackers from compromising our security and stealing our latest technology. .

Glazed Panel Construction with Human-Robot Cooperation
by Seungyeol LeeThese days, construction companies are beginning to be concerned about a potential labor shortage by demographic changes and an aging construction work force. Also, an improvement in construction safety could not only reduce accidents but also decrease the cost of the construction, and is therefore one of the imperative goals of the construction industry. These challenges correspond to the potential for Automation and Robotics in Construction as one of solutions. Almost half of construction work is said to be material handling and materials used for construction are heavy and bulky for humans. To date, various types of robots have been developed for glazed panel construction. Through the case studies on construction, to which the robots were applied, however, we identified difficulties to be overcome. In this study, a human-robot cooperative system is deduced as one approach to surmount these difficulties; then, considerations on interactions among the operator, robot and environment are applied to design of the system controller. The human-robot cooperative system can cope with various and construction environments through real-time interaction with a human, robot and construction environment simultaneously. The physical power of a robot system helps a human to handle heavy construction materials with a relatively scaled-down load. Also, a human can feel and respond to the force reflected from robot end effecter acting with working environment. Through the experiments and mock-up tests with a prototype robot, we observe the characteristics of the power assist and the force reflection, the merits of the human-robot cooperation system. To apply human-robot cooperative system at real construction sites, Glazed Ceiling Panel Construction Robot is developed for the first time. This robot is distinguished from other glazed panel construction robots because of the methods of lifting the panel to high installation positions and installing the fragile and bulk panel with robot force control. After applying to real construction sites, evaluation on the productivity of the developed robot was done by comparing and analyzing with the existing installation methods.
