title: Moderating effects of perceived control and need for clarity on the relationship between role stressors and employee affective reactions.

authors: O’Driscoll, Michael P.

subjects: psychology

abstract: The authors examined the salience of perceived control and need for clarity as “buffers” of the adverse consequences of role stressors by using hierarchical regressions on role ambiguity and role conflict, with job satisfaction and psychological strain as the criterion variables. In a sample of U.S. and New Zealand employees, perceived control was directly associated with higher satisfaction and reduced strain but displayed no moderating effect on stressor-outcome relationships. Need for clarity, on the other hand, was a significant moderator of the relationship of role ambiguity and conflict to both satisfaction and strain; that finding suggests that researchers could give more attention to dispositional variables in examining the correlates of role stressors.

title: Diacritic Restoration and the Development of a Part-of-Speech Tagset for the Māori Language

authors: Cocks, John

subjects: Māori

abstract: This thesis investigates two fundamental problems in natural language processing: diacritic restoration and part-of-speech tagging. Over the past three decades, statistical approaches to diacritic restoration and part-of-speech tagging have grown in interest as a consequence of the increasing availability of manually annotated training data in major languages such as English and French. However, these approaches are not practical for most minority languages, where appropriate training data is either non-existent or not publically available. Furthermore, before developing a part-of-speech tagging system, a suitable tagset is required for that language. In this thesis, we make the following contributions to bridge this gap:

Firstly, we propose a method for diacritic restoration based on naive Bayes classifiers that act at word-level. Classifications are based on a rich set of features, extracted automatically from training data in the form of diacritically marked text. This method requires no additional resources, which makes it language independent. The algorithm was evaluated on one language, namely Māori, and an accuracy exceeding 99% was observed.

Secondly, we present our work on creating one of the necessary resources for the development of a part-of-speech tagging system in Māori, that of a suitable tagset. The tagset described was developed in accordance with the EAGLES guidelines for morphosyntactic annotation of corpora, and was the result of in-depth analysis of the Māori grammar.
