Second Handbook of Information Technology in Primary and Secondary Education
by Joke Voogt Gerald Knezek Rhonda Christensen Kwok-Wing LaiIn this second edition the editors continue their efforts to synthesize research and practice and project future directions in the field of information and communication technology. The proliferation of mobile devices and applications have had major implications on how the nature of teaching and learning should be conceptualised, and what pedagogical practices should be used to support bridging formal and informal learning. The advent of social media also highlights the importance of gaining a deeper understanding of social learning theories and computer-supported collaborative learning theories and practices. The advancement of new technologies to support easy accessibility of educational resources such as OER and to a lesser extent MOOCs have led to the debate on how assessment should be conducted and how technologies could be used to support it. The demand of the knowledge society requires that researchers, policy makers, and educational practitioners be conversant with new research findings in order to understand the impact of ICT in teaching and learning, and how to support learners to use new technologies and applications creatively and effectively. New research paradigms have emerged to meet these challenges.

Second Lives: A Journey Through Virtual Worlds
by Tim GuestWe've always dreamed of perfect places: Eden, heaven, Oz Â- places over the rainbow, beyond death and loss. Now, through computer technology, we can inhabit those worlds together. Each week, between 35 and 50 million people worldwide abandon reality for virtual worlds. In Boston, Massachusetts, a group of nine disabled men and women inhabit one virtual body, which frees them from their lifelong struggle to be seen and heard. The Pentagon has begun to develop virtual worlds to help in real-world battles. In Korea, where one particular game has 8 million residents, virtual violence has spread into the real world. Fortunes have been made, and mafia gangs have emerged to muscle in on the profits. In these new computer-generated places, which at first glance seem free from trouble and sorrow, you can create a new self. With the click of a mouse you can select eye colour, face shape, height, even wings. You can build houses, make and sell works of art, earn real money, get married and divorced. On websites like eBay, people sell virtual clothes and rent virtual property for real cash - for a total of £400 million worth each year. Tim Guest takes us on a revelatory journey through the electronic looking-glass, as he investigates one of the most bizarre phenomena of the 21st century.
Second Time Around: From Art House to DVD
by D. A. MillerThe art houses and cinema clubs of his youth are gone, but the films that D. A. Miller discovered there in the 1960s and ’70s are now at his fingertips. With DVDs and streaming media, technology has turned the old cinematheque’s theatrical offerings into private viewings that anyone can repeat, pause, slow, and otherwise manipulate at will.In Second Time Around, Miller seizes this opportunity; across thirteen essays, he watches digitally restored films by directors from Mizoguchi to Pasolini and from Hitchcock to Honda, looking to find not only what he first saw in them but also what he was then kept from seeing by quick camerawork, normal projection speed, missing frames, or simple censorship. At last he has an unobstructed view of the gay leather scene in Cruising, the expurgated special effects in The H-Man, and the alternative ending to Vertigo. Now he can pursue the finer details of Chabrol’s debt to Hitchcock, Visconti’s mystificatory Marxism, or the unemotive emotion in Godard.Yet this recaptured past is strangely disturbing; the films and the author have changed in too many ways for their reunion to be like old times. The closeness of Miller’s attention clarifies the painful contradictions of youth and decline, damaged prints and flawless restorations.
Secondary Liability of Internet Service Providers
by Graeme B. DinwoodieThis book analyses the doctrinal structure and content of secondary liability rules that hold internet service providers liable for the conduct of others, including the safe harbours (or immunities) of which they may take advantage, and the range of remedies that can be secured against such providers. Many such claims involve intellectual property infringement, but the treatment extends beyond that field of law. Because there are few formal international standards which govern the question of secondary liability, comprehension of the international landscape requires treatment of a broad range of national approaches. This book thus canvasses numerous jurisdictions across several continents, but presents these comparative studies thematically to highlight evolving commonalities and trans-border commercial practices that exist despite the lack of hard international law. The analysis presented in this book allows exploration not only of contemporary debates about the appropriate policy levers through which to regulate intermediaries, but also about the conceptual character of secondary liability rules.
Secrecy, Covertness and Authentication in Wireless Communications: Physical Layer Security Approach (Wireless Networks)
by Xiaohong Jiang Yulong Shen Yuanyu ZhangThis book introduces the fundamentals of physical layer security (PLS) and demonstrates how a variety of PLS techniques can be applied to improve the security of wireless communication systems. In particular, this book covers three security aspects of wireless communications. It includes secrecy, i.e., preventing eavesdroppers from intercepting information from transmitted wireless signals, covertness, i.e., hiding the transmitted signals themselves from malicious wardens and authentication, i.e., authenticating the identities of communicating entities. When discussing the secrecy of wireless communication systems, this book covers physical layer secure communication in multiple-input multiple-out (MIMO) systems based on beamforming and precoding techniques, in relay systems based on link/relay selection and in large-scale random networks based on cooperative jamming. Regarding the covertness of wireless communication systems, this book introduces physical layer covert communication in relaying systems and MIMO systems. Also, when discussing authentication in wireless communication systems, this book introduces the implementation of physical layer authentication in MIMO systems based on channel features and/or radiometric features of transceivers. In addition, this book presents security-aware routing in wireless networks based on physical layer secure communication techniques.This book targets researchers in the fields of physical layer security and wireless communications security. Advanced-level students in electronic engineering or computer science studying these security topics will also want to purchase this book as a secondary textbook.
