The need for nodes to be able to generate their own address and verify those from others, without relying on a global trusted authority, is a well-known problem in networking. One popular technique for solving this problem is to use self-certifying addresses that are widely used and standardized; a prime example is cryptographically generated addresses (CGA). We re-investigate the attack models...

Introduction The purpose of this study was to determine if online homework using MyMathLab (MML) would lead to an increase in academic performance compared with traditional paper-based, instructor-graded homework. Seventy-two students enrolled in a required college algebra course participated in this study. Results from this study indicate that there is not enough evidence to claim that the stu...

This study investigated the factors influencing trust in travel-related CGM and the degree to which trust affects the benefits and impacts of using CGM when planning pleasure trips. An online survey of US Internet users was conducted with a total of 1170 individuals responding to questions regarding their perceptions and use of CGM for travel planning. The findings show that CGM use is widespre...

Our work demonstrates how proactive context-aware service provisioning has been deployed in the DYNAMOS System to address the needs of typical recreational boaters. We show by means of several usage scenarios how our system constantly provides mobile users with services that fit them in their current context. Furthermore, the system enables users to create and to share with peers user-generated...

This research builds on the literature on information technology and organizations to suggest an alternative to the current understanding of the production of computer-generated representations of work. This literature sees computer-generated representations of work as automatic outcomes of information technology that managers use to scrutinize employees. We present a ethnography of a desk-base...

Composition conventions are guidelines used by human composers in composing chess problems. They are particularly significant in composition tournaments. Examples include, not having any ‘check’ in the first move of the solution and not ‘dressing up’ the board with unnecessary pieces. Conventions are often associated or even directly conflated with the overall aesthetics or beauty of a composit...

We document the creation of a new set of OpenMath content dictionaries to support the expression of quantities and units under the International System of Units (SI). While preserving many of the concepts embodied in the original content dictionaries, these new content dictionaries provide a foundation for quantities and units that is compliant with international standards. We respond to questi...

Assessing the quality of user generated content is an important problem for many web forums. While quality is currently assessed manually, we propose an algorithm to assess the quality of forum posts automatically and test it on data provided by Nabble.com. We use state-of-the-art classification techniques and experiment with five feature classes: Surface, Lexical, Syntactic, Forum specific and...

This article presents the potential for new business models in the context of user-generated content and services in the mobile environment. The approach is based on the concept of a new platform that incorporates multiple (mobile) network providers as well as private and commercial third party content and service providers. The potential for gaining and sharing revenues among the different par...

The focus of this work is in modeling the unique sound and the playing practices of the acoustic guitar. The results can be applied to other plucked string instruments too. A new extended notation package is used to produce expressive control information. This tool allows the user to add to the input score instrumental expressions and tempo functions. The system includes also a rule formalism t...
