A Lagrangian moisture source attribution model and analysis of southern Africa
Lagrangian moisture source attribution model is developed in order to explore the regional moisture source dynamics of southern Africa. In particular, the model was developed in order to explore the role of the regional land surface as a source of moisture for regional precipitation. This work was …

Applications of Machine Learning in Source Attribution and Gene Function Prediction
… two distinct domains: (1) the predicting the source of bacterial pathogen using whole genome sequencing data, and (2) the functional annotation of genes using single- cell RNA sequencing data. This work proposes the development of a bioinformatics pipeline tailored for identifying genomic …

News sources and perceptual effects: an analysis of source attribution within news coverage of alleged terrorist plots.
Studies of source-media relations have tended towards two principal frameworks for analysis: developing a structural approach, where access is determined by the source's position within the dominant hegemony (Hall et al. 1978); or through sociological enquiries, which examine the relationship …

Investigating the Effect of Attentional Control on Source Monitoring and DRM Memory Performance
… over gist-based processing. Studies examining source monitoring in DRM paradigms have highlighted the importance of attentional control (AC), with divided attention (DA) during encoding leading to impaired source detail recollection. This thesis examined how AC affected the accuracy of source …

The effects of using process accountability and outcome accountability on susceptibility to directional goals: an examination of management's memory in financial reporting
… in the context of managers’ memory for the source of information. Integrating psychology theory, I examine how the type of accountability (outcome or process) interacts with managers’ situational preferences to influence management’s accuracy and confidence in its memory for the source of …
