Currently, losing a security token places the user in a dilemma: reporting the loss as soon as it is discovered involves a significant burden which is usually overkill in the common case that the token is later found behind a sofa. Not reporting the loss, on the other hand, puts the security of the protected account at risk and potentially leaves the user liable. We propose a simple architectur...

This work will examine the link between intrinsic motivation and external rewards by describing the experiences of twenty-seven academically under-performing adolescents who were enrolled in an after school program in a New York City public junior high school that implemented a token economy. The goals of the implemented token economy were to establish an objective measure of student competence...

Formant frequency data for Catalan vowels reveal essentially the same degree of expansion for three dialect systems with seven vowels (Valencian, Eastern Catalan, Western Catalan). A slightly larger vowel space dispersion for a fourth system with those same vowels and stressed /c/ (Majorcan) is not clearly associated with a larger vowel system size but rather with a local effect of schwa in rep...

We present an analysis of parser performance on speech data, comparing word type and token frequency distributions with written data, and evaluating parse accuracy by length of input string. We find that parser performance tends to deteriorate with increasing length of string, more so for spoken than for written texts. We train an alternative parsing model with added speech data and demonstrate...

We describe a mechanism for automatically acquiring verb subcategorization frames and their frequencies in a large corpus. A tagged corpus is first partially parsed to identify noun phrases and then a finear grammar is used to estimate the appropriate subcategorization frame for each verb token in the corpus. In an experiment involving the identification of six fixed subcategorization frames, o...

This abstract describes a new approach to token management for in-home digital networks, which we call RTnet. The proposed network offers a guaranteed quality-of-service, based on a distributed token mechanism to schedule communication streams. RTnet is based on the CSMA/CD Ethernet protocol [1]. In effect this means that RTnet can be built on any existing Ethernet specification and regular Eth...

1. Indexicality in language and thought As expression types, indexicals do not refer. Only tokens of an indexical refer, because indexical reference is achieved through relations between tokens of the indexical and other entities in the context of tokening ; entities which gain their status as referent in virtue of standing in these relations to the relevant token. For example, a token of 'I' r...
