Meat consumption and type 2 diabetes: investigating heterogeneity and potential causal mechanisms
… Finally, there are uncertainties about the causal nature of the association and the mechanisms that may underlie it. In my PhD, I aimed to investigate these uncertainties in analyses of epidemiological studies. The initial elements of my work focused on refining measures of the exposure …

Performance effects and causal mechanisms of mid-channel congestion in diesel particulate filters
The diesel particulate filter (DPF) is a ~$5,000-$50,000 USD critical component of aftertreatment systems installed in diesel engine-powered vehicles. The device is designed to trap particles emitted by the diesel combustion process in order to prevent their release into the surrounding …

Traumatic Brain Injury As An Environmental Risk Factor For Neurodegeneration: Elucidating Causal Mechanisms With Drosophila
… Even single TBIs contribute to the degenerative mechanisms, putting survivors of TBI at an increased risk for developing various neurodegenerative diseases including dementias such as Alzheimer’s disease, motor neuron disease, Parkinson’s disease and chronic traumatic encephalopathy. To study the …

How Unreliable are adult-reported suicide attempts? An examination of correlates and underlying causal mechanisms of discordant reporting over time
… across studies, I posited four plausible causal mechanisms underlying discordant suicidality reporting; recall failure, reinterpretation, conscious denial, and lack of construct comprehension. Extending these findings, I proposed that the likelihood of each mechanism is influenced by …

Causal inference in integrative genomics: exploring de novo mutations and unravelling causal mechanisms via gene regulatory networks in developmental process
… genomics and transcriptomics data to perform causal inference on DNMs occurring in the germline. These germline DNMs have long been implicated as significant contributors to developmental and genetic disorders. Previous investigations of the genetic factors influencing DNMs have been hindered …

Employee flourishing: The application and efficacy of workplace coaching as a methodology for improving mental well-being
… What are the contributing processes and causal mechanisms of workplace coaching? A critical realist, mixed methods research design was adopted which involved three phases of participants (n=47) who undertook either a coaching/training programme; workplace coaching; or no intervention …

The role of the bidding process in the corporate governance of bidding firms: the case of abandoned acquisitions
… addresses this gap, by investigating the causal mechanisms of abandoned acquisitions and their aftermath. The thesis develops an innovative, multi-dimensional conceptual framework, blending existing theories of acquisitions and corporate governance. This framework guides the empirical …

Feeding facilitation, the hidden interaction in mammalian herbivore assemblages?: a case-study on rabbits (Oryctolagus cuniculus L.) and large grazers
… hypothesis could not be affirmed, although some causal mechanisms of feeding facilitation have been affirmed. We suggest that feeding facilitation is not necessarily absent, but is hard to detect or is not present under particular conditions. Experimental research is needed for further …

Female Legislators and the Power of the Purse: Does Gender Affect Government Spending? A Cross-National Analysis
… a mixed methods approach to identify the causal mechanisms between female legislators and government spending outcomes. I constructed a substantial cross-national, time-series data set, which tracks spending in defense, education, childcare, and maternity/paternity leave spending during a …

Outcomes of Platform Openness in Complementary Markets
… performance outcomes. We unravel important causal mechanisms related to competition dynamics between new entrants and incumbent complements. In the second essay, we explore the impact of platform competing APIs on incumbent capability-like complements. We shed light on the spillover effects …

Exploring middle school students' sensemaking of a gesture-augmented computer simulation depicting thermal conduction
… computer simulation to develop a causal-mechanistic explanation of thermal conduction through a silver spoon. The computer simulation is a dynamic molecular model of a spoon that depicts the causal-mechanism of the spoon’s molecules moving to explain how heat transfer occurs. …

Domestic work in Cape Town: an exploration into the growth of part-time domestic work
… A critical realist approach seeks to explain causality through understanding the qualitative properties which create, determine or generate relations and objects. Therefore, the qualitative research uncovers and describes some of the causal mechanisms behind the growth of part-time domestic …
