Handling Concept Drift In The Context Of Expensive Labels, Patrick Lindstrom
Handling Concept Drift In The Context Of Expensive Labels, Patrick Lindstrom
Doctoral
Machine learning has been successfully applied to a wide range of prediction problems, yet its application to data streams can be complicated by concept drift. Existing approaches to handling concept drift are overwhelmingly reliant on the assumption that it is possible to obtain the true label of an instance shortly after classification at a negligible cost. The aim of this thesis is to examine, and attempt to address, some of the problems related to handling concept drift when the cost of obtaining labels is high. This thesis presents Decision Value Sampling (DVS), a novel concept drift handling approach which periodically …

Gender And Ses Effects On Multidimensional Self-Concept Development During Adolescence, Patricia Meredith Orr
Doctoral
The present study constitutes an integral part of the Dublin Child Development Study, a longitudinal study which began in 1986 and which has had eight waves of data collection since its inception. Using data collected during two of these waves, multidimensional self-concept status of 72 participants (F = 40, M = 32) was examined at 10 (T1) and 17 (T2) years of age. Longitudinal changes in multidimensional self-concept between T1 and T2 were also examined. The Shavelson Hubner and Stanton Structural Model (1976) was used as the theoretical basis for this research; this model emphasises the multidimensionality of the self-concept …

Licensed To Care: Inhabiting The Transnational Economy Of "Global Pinoy", Fidel Taguinod
Doctoral
The Philippines’ experience in international labour migration is widely considered a success – an observation endorsed by international bodies such as the World Health Organisation. As an active source of professional nurses to the developed world, the country continues to produce more nurses than the local nursing market can employ; a labour strategy that is promoted, facilitated and supported by the Philippine state and nursing educational system. This thesis interrogates Filipino nurse migration through the methodological prism of autoethnography, drawing on first-hand experience and reflexive accounts, interviews, photographs, policy documents and material cultural artefacts, to critically examine and challenge the …
