The imperfect observer: Mind, machines, and materialism in the 21st century
The dualist / materialist debates about the nature of consciousness are based on the assumption that an entirely physical universe must ultimately be observable by humans (with infinitely advanced tools). Thus the dualists claim that anything unobservable must be non-physical, while the materialists argue that in theory nothing is unobservable. However, there may be fundamental limitations in the power of human observation, no matter how well aided, that greatly curtail our ability to know and observe even a fully physical universe. This paper presents arguments to support the model of an inherently limited observer and explores the consequences of this view
Multimedia search without visual analysis: the value of linguistic and contextual information
This paper addresses the focus of this special issue by analyzing the potential contribution of linguistic content and other non-image aspects to the processing of audiovisual data. It summarizes the various ways in which linguistic content analysis contributes to enhancing the semantic annotation of multimedia content, and, as a consequence, to improving the effectiveness of conceptual media access tools. A number of techniques are presented, including the time-alignment of textual resources, audio and speech processing, content reduction and reasoning tools, and the exploitation of surface features
Pervasively Distributed Copyright Enforcement
In an effort to control flows of unauthorized information, the major copyright industries are pursuing a range of strategies designed to distribute copyright enforcement functions across a wide range of actors and to embed these functions within communications networks, protocols, and devices. Some of these strategies have received considerable academic and public scrutiny, but much less attention has been paid to the ways in which all of them overlap and intersect with one another. This article offers a framework for theorizing this process. The distributed extension of intellectual property enforcement into private spaces and throughout communications networks can be understood as a new, hybrid species of disciplinary regime that locates the justification for its pervasive reach in a permanent state of crisis. This hybrid regime derives its force neither primarily from centralized authority nor primarily from decentralized, internalized norms, but instead from a set of coordinated processes for authorizing flows of information. Although the success of this project is not yet assured, its odds of success are by no means remote as skeptics have suggested. Power to implement crisis management in the decentralized marketplace for digital content arises from a confluence of private and public interests and is amplified by the dynamics of technical standards processes. The emergent regime of pervasively distributed copyright enforcement has profound implications for the production of the networked information society
The Place of the User in Copyright Law
Copyright doctrine . . . is characterized by the absence of the user. As copyright moves into the digital age, this absence has begun to matter profoundly. As I will show, the absence of the user has consequences that reach far beyond debates about the legality of private copying, or about the proper scope of user-oriented exemptions such as the fair use and first sale doctrines. The user\u27s absence produces a domino effect that ripples through the structure of copyright law, shaping both its unquestioned rules and its thorniest dilemmas. The resulting imbalance - empty space where one cornerstone of a well-balanced copyright edifice should be - makes for bad theory, bad policy, and bad law
Handmade films and artist-run labs. The chemical sites of filmâs counterculture
This article addresses handmade films and especially artist-run labs as sites of hands-on film culture
that reactivate moments and materials from media history. Drawing on existing research, discourses
and discussions with contemporary experimental filmmakers affiliated with labs or practicing their
work in relation to film lab infrastructure, we focus on these sites of creation, preservation and
circulation of technical knowledge about analog film. But instead of reinforcing the binary of
analog vs. digital, we argue that the various material practices from self-made apparatuses to
photochemistry and film emulsions are ways of understanding the multiple materials and layered
histories that define post-digital culture of film. This focus links our discussion with some themes in
media archaeology (experimental media archaeology as a practice) and to current discussions about
labs as arts and humanities infrastructure for collective project and practice-based methods
Opaque Service Virtualisation: A Practical Tool for Emulating Endpoint Systems
Large enterprise software systems make many complex interactions with other
services in their environment. Developing and testing for production-like
conditions is therefore a very challenging task. Current approaches include
emulation of dependent services using either explicit modelling or
record-and-replay approaches. Models require deep knowledge of the target
services while record-and-replay is limited in accuracy. Both face
developmental and scaling issues. We present a new technique that improves the
accuracy of record-and-replay approaches, without requiring prior knowledge of
the service protocols. The approach uses Multiple Sequence Alignment to derive
message prototypes from recorded system interactions and a scheme to match
incoming request messages against prototypes to generate response messages. We
use a modified Needleman-Wunsch algorithm for distance calculation during
message matching. Our approach has shown greater than 99% accuracy for four
evaluated enterprise system messaging protocols. The approach has been
successfully integrated into the CA Service Virtualization commercial product
to complement its existing techniques.Comment: In Proceedings of the 38th International Conference on Software
