In Optimality Theory, an important tool for accounting for morpho-phonological processes is output-output correspondence. A development of this approach is Transderivational Anti-Faithfulness (TAF), constituting a reversal of faithfulness. This article will explore the nature of TAF, in order to test this approach as an extension of Optimality Theory. The example of morphologically triggered ac...

This paper proposes a study of the effects of knowledge management systems (KMS) on individual and organizational performance. The study seeks to answer the following question: Which factors determine the impact of KMS on performance by individuals and groups? A model for KMS and performance is developed. This model takes the special characteristics of KMS into account, and extends the theory o...

Spirtes, Glymour and Scheines [Causation, Prediction, and Search (1993) Springer] described a pointwise consistent estimator of the Markov equivalence class of any causal structure that can be represented by a directed acyclic graph for any parametric family with a uniformly consistent test of conditional independence, under the Causal Markov and Causal Faithfulness assumptions. Robins et al. [...

In a recent paper, Cheng, Greiner, Kelly, Bell and Liu (Artificial Intelligence 137:4390; 2002) describe an algorithm for learning Bayesian networks that—in a domain consisting of n variables—identifies the optimal solution using O(n) calls to a mutual-information oracle. This seemingly incredible result relies on (1) the standard assumption that the generative distribution is Markov and faithf...

Melissa Frazier: Accent In Proto-Indo-European Athematic Nouns: Antifaithfulness in Inflectional Paradigms (Under the direction of Jennifer L. Smith) This paper examines four accent patterns displayed by athematic nouns in Proto-Indo-European. Each accent pattern is distinguished by either alternating stress or vowel quality between " weak " forms (nominative, accusative, vocative) and " strong...
