I he issue about whethei Philosophy has become redundant in our time constitutes one o f the initial or beginning issues in Philosophy. Philosophy, which is, broadly speaking, one oj the humanities, is not anil may not be a product oj socio-economic relations. When these disciplines concede that they have become encapsulated in the existing order and that therefore they wish to continue the sta...

We study second-degree price discrimination in markets where the product traded by the monopolist is access to other agents. We derive necessary and sufficient conditions for the welfareand the profit-maximizing mechanisms to employ a single network or a menu of non-exclusive networks. We characterize the optimal matching schedules under a wide range of preferences, derive implications for pric...

The goal of this paper is to explore qualities of mathematical imagination in light of a classroom episode. It is based on the analysis of a classroom interaction in a high school Algebra class. We examine a sequence of nine utterances enacted by one of the students whom we call Carlene. Through these utterances Carlene illustrates, in our view, two phenomena: (1) juxtaposing displacements, and...

Despite much progress, it remains challenging to develop new visualization systems, predict their qualities, and understand design trade-offs. We propose an empirical framework for Information Visualization (InfoVis) theories consisting of a context space, a visualization space, visualization metrics, and visualization principles. Using this framework, we identify 5 possible steps to advance In...

A number of clinical coding and vocabulary schemes are in use in healthcare enterprises today. Most of them are weak in light of the qualities that characterize adequate controlled medical terminologies, as outlined in Part One of this review. Here we look at the major code and terminology sets with a critical eye, as well as suggest practical steps to enable health industry information system ...

This paper will attempt to define a new area of research: affective communication through the use of affective objects. An affective object may be defined as any physical object which has the ability to sense emotional data from a person, map that information to an abstract form of expression and communicate that information expressively, either back to the subject herself or to another person....

Skill Uncertainty and Social Inference Research in psychology indicates that individuals often make inferences regarding unknown individual qualities based on potentially irrelevant (but socially observable) information. This paper explores occupational choices when individuals receive imprecise signals regarding ability and use the observable characteristics of previously successful individual...

Security is a fundamental issue for promising applications in a VANET. Designing a secure protocol for a VANET that accommodates efficiency, privacy, and traceability is difficult because of the contradictions between these qualities. In this paper, we present a secure yet efficient protocol for a VANET that satisfies these security requirements. Although much research has attempted to address ...

Traditional recommender system evaluation focuses on raising the accuracy, or lowering the rating prediction error of the recommendation algorithm. Recently, however, discrepancies between commonly used metrics (e.g. precision, recall, root-mean-square error) and the experienced quality from the users’ have been brought to light. This project aims to address these discrepancies by attempting to...
