Consider an agent who enters a financial market on day t = 0 with an initial capital amount x. He invests this amount on stocks and the money market, and by day t = τ , has generated a wealth W . He is given a convex class of probability measures or scenarios and a real-valued floor corresponding to each scenario. The agent faces the constraints that the expectation of W under each scenario mus...

Alzheimer’s Disease, as other mental and neurological disorders, is difficult to diagnose since it affects several cognitive abilities shared with other impairments. Current diagnostic mainly consists of neuropsychological tests and history obtained from the patient and relatives. In this paper we propose a methodology for the characterization of probable AD based on the computational cognitive...

In this study, we compared three long-term fundamental frequency estimates – mean, median and base value – with respect to how fast they approach a stable value, as a function of language, speaking style and speaker. The base value concept was developed in search for an f0 value which should be invariant under prosodic variation. It has since also been tested in forensic phonetics as a possible...

I coin the term ‘emotive markers’ to describe words like alas which encode not-at-issue information about the speaker’s emotive attitude towards the content of the utterances they occur in. I argue that there are important differences emotive markers and encoders of canonical not-at-issue content, like the utterance modifier frankly or the evidential adverb apparently. In contrast to the latter...

Resolution is an integral part of all forms of data. This paper presents a framework for quantifying, reasoning with and managing multi-resolution object-based data. The framework differs from other approaches in that it handles resolution at the object level explicitly. It defines a basic set of operations for changing an object’s resolution that can be utilized for generalization, consistency...

It has been claimed that tone language speakers use less F0 related cues in the production of verbal expressions of emotions. This is because F0 is used in the production of lexical tones. This study investigated this claim by examining how F0 and various other acoustic parameters are used in the production of verbal emotion expressions in Cantonese (tone language) compared to English (non-tone...

This paper determines variables that influence the students’ utilization and perception of online discussions in developing countries. It applies criteria found in developed countries to developing countries to define whether these criteria fit or need adoption to be useful for implementation. This paper is based on a comparison of two courses offered at the University of Botswana. Quantitative...

Recent empirical research seems to show that emotions play a substantial role in moral judgment. Perhaps the most important line of support for this claim focuses on disgust. A number of philosophers and scientists argue that there is adequate evidence showing that disgust significantly influences various moral judgments. And this has been used to support or undermine a range of philosophical t...

An essential function of language processing is serial order control. Computational models of serial ordering and empirical data suggest that plan representations for ordered output of sound are governed by principles related to similarity. Among these principles, the temporal distance and edge principles at a within-word level have not been empirically demonstrated separately from other princi...

CIRCSIM-Tutor v. 3 differs from many other ITSs in that text planning is an integral part of the system rather than part of a natural-language front-end. It contains a global planner whose fundamental goal i s "generate a conversation resulting in the student knowing " rather than "teach ." Constraints on the plan operators can be used to take a variety Of knowledge Sources ...
