The debate over the contribution of the Internet to democracy is farfrom settled. Some point to the empowering effects of online discussionand fund raising on recent electoral campaigns in the US to argue thatthe Internet will restore the public sphere. Others claim that the Internetis just a virtual mall, a final extension of global capitalism into everycorner of our lives. This paper argues f...

content creators: Some social and legal implications Abstract Consumers are increasingly turning to the online environment to provide information to assist them in making purchase decisions related to travel products. They often rely on travel recommendations from different sources, such as sellers, independent experts and, increasingly, other consumers. A new type of online content, user-gener...

¡v in this paper we consider a strongly regular relation ƒá on hypermodules so that the quotient is amodule (with abelian group) over a fundamental commutative ring. also, we state necessary and sufficientconditions so that the relation ƒá is transitive, and finally we prove that ƒá is transitive on hypermodules.

In this thesis we study algorithms for online convex optimization and their relation to approximate optimization. In the first part, we propose a new algorithm for a general online optimization framework called online convex optimization. Whereas previous efficient algorithms are mostly gradient-descent based, the new algorithm is inspired by the Newton-Raphson method for convex optimization, a...

Kim argues that weak and global supervenience are too weak to guarantee any sort of dependency. Of the three original forms of supervenience, strong, weak, and global, each commonly wielded across all branches of philosophy, two are thus cast aside as uninteresting or useless. His arguments, however, fail to appreciate the strength of weak and global supervenience. I investigate what weak and g...

Teaching online is part of the everyday practice of many academics and student evaluation of that teaching is an expected activity of both individuals and institutions in today’s higher education context. Yet, conversations about the ethical questions raised when technology, teaching and evaluation intersect in the online learning context are rare. This paper employs an ethical framework compos...

This paper proposes an efficient online method that trains a classifier with many conjunctive features. We employ kernel computation called kernel slicing, which explicitly considers conjunctions among frequent features in computing the polynomial kernel, to combine the merits of linear and kernel-based training. To improve the scalability of this training, we reuse the temporal margins of part...

We propose a content-based approach to explorative visualization of online audio streams (e.g., web radio streams). The visualization space is defined by prototypical instances of musical concepts taken from personal music collections. Our system shows the relation of prototypes to each other and generates an animated visualization that places representations of audio streams in the vicinity of...
