Self-archiving and the Copyright Transfer Agreements of ISI-ranked library and information science journals

A study of Thomson-Scientific ISI ranked Library and Information Science (LIS) journals (n = 52) is reported. The study examined the stances of publishers as expressed in the Copyright Transfer Agreements (CTAs) of the journals toward self-archiving, the practice of depositing digital copies of one\u27s works in an Open Archives Initiative (OAI)-compliant open access repository. Sixty-two percent (32) do not make their CTAs available on the open Web; 38% (20) do. Of the 38% that do make CTAs available, two are open access journals. Of the 62% that do not have a publicly available CTA, 40% are silent about self-archiving. Even among the 20 journal CTAs publicly available there is a high level of ambiguity. Closer examination augmented by publisher policy documents on copyright, self-archiving, and instructions to authors reveals that only five, 10% of the ISI-ranked LIS journals in the study, actually prohibit self-archiving by publisher rule. Copyright is a moving target, but publishers appear to be acknowledging that copyright and open access can co-exist in scholarly journal publishing. The ambivalence of LIS journal publishers provides unique opportunities to members of the community. Authors can self-archive in open access archives. A society-led, global scholarly communication consortium can engage in the strategic building of the LIS information commons. Aggregating OAI-compliant archives and developing disciplinary-specific library services for an LIS commons has the potential to increase the field\u27s research impact and visibility. It may also ameliorate its own scholarly communication and publishing systems and serve as a model for others

Novel countermeasures and techniques for differential power analysis

Research in the last few years has indicated that, despite modern algorithms being secure against all published mathematical attacks and being far too complex to break by brute force, secret key data can be gathered by monitoring the power consumption. This is known as a power analysis attack, the most successful has been differential power analysis (DPA). Several countermeasures have been proposed for preventing power analysis attacks with varying degrees of efficacy. One thing all the countermeasures have in common is their large cost in terms of performance and or cost. In this thesis several modifications to the AES algorithm are proposed that seek to inherently secure it against DPA and their effectiveness and cost are investigated.Due to the statistical nature of DPA there is no set amount of power consumption data that will always give the correct result for a given device, rather, a value for the SNR and the number of power measurements involved in the attack will equate to a probability of success. In this thesis a statistical model of the DPA attack is derived and it is used to find a method for calculating the probability that a particular attack will be successful. A more benign use for DPA is also discussed. If the signature of a specific pattern of register transitions can be detected in the power consumption of a device then designers can add hardware whose sole purpose is to be detectable in a power trace and act as a watermark to prove the presence of intellectual property

Animated 'worlds'

Animated ‘Worlds’ is an edited compilation of the papers presented at the Animated ‘Worlds’ conference held in 2003 at Farnham Castle, UK. What do we mean by the term ‘animation’ when we are discussing film? Is it a technique? – A style? – A way of seeing or experiencing ‘a world’ that has little relation to our own lived experience of ‘the world’? The Animated ‘Worlds’ anthology presents a selection of topics from the 2003 Animated ‘Worlds’ conference held in England. Essays range from close film analyses to phenomenological and cognitive approaches, spectatorship, performance, literary theory and digital aesthetics that reveal the astonishing variety of ‘worlds’ animation confronts us with. The authors are: Suzanne Buchan (Editor), Heather Crow, Miriam Harris, Rachel Kearney, Thomas Lamarre, Vivian Sobchack, David Surman, Paul Ward, Karin Wehn, Richard Weihe, Paul Wells and Suzanne Williams-Rautiola

Pervasive animation

This new addition to the AFI Film Readers series brings together original scholarship on animation in moving image culture, from classic, experimental, and independent shorts to digital animation and installation. The collection aims to foreground new critical perspectives on animation, connect them to historical and contemporary philosophical and theoretical contexts and production practice, and expand the existing canon. Throughout, contributors offer an interdisciplinary roadmap of new directions in film and animation studies, discussing animation in relationship to aesthetics, ideology, philosophy, historiography, visualization, genealogies, spectatorship, representation, technologies, and material culture
