The Context-Dependence of the Process of Risky Choice
… process across high and low volatility contexts in risky choice. Due to the brain's computational capacity limitations, perception is optimized to detect differences within a narrow range of stimuli. We show that this adaptation process is itself context-dependent, with stronger …

Context dependence of Physics students' responses to the term "radiation"
… depending on the situation at hand and that context plays an important role in how students respond to questions. Thus, the thesis explores to what extent context plays a role in their responses by preceding the question with four different scenarios which are suggested as the contexts in …

Functional modularity in gene networks
This thesis addresses two sources of context-dependence in both systems and synthetic biology: retroactivity and competition for shared cellular resources. The contribution is the development of simple-to-use computational tools that aide the analysis and design of multi-module genetic systems. …

Loading as a design parameter for genetic circuits
… building complex biomolecular circuits is due to context-dependence: the dynamics of a system are altered upon changes to its context, potentially degrading the system's performance. In this thesis, we study retroactivity, a specific type of context-dependence, by analyzing the effects of loads on …

The Structural Distribution of Epistasis in a Pair of Essential Metabolic Enzymes
… effect of a mutation in unexpected ways. This context-dependence of mutational effects is epistasis. Extensive progress has been made in our ability to identify epistasis between proteins. However, how the epistasis between a pair of proteins is distributed across the amino acid sequence is …

The Influence of Multiple Scales of Environmental Context on the Distribution and Interaction of an Invasive Seagrass and its Native Congener
… species impacts is complicated by the variable context in which they occur. Furthermore, species invasion is an inherently multi-scale process, war- ranting examination at multiple spatial scales. In its introduced range, the invasive seagrass <italic>Zostera japonica</italic> often grows at …

Nature-Based Coastal Adaptation: A Comparative Assessment to Inform Effective Implementation
… landscape, inconsistent planning tools, and the context dependence of NbS design. This thesis aims to explore these diverse uncertainties in detail by shedding light on the key factors and processes that may pose critical barriers or drive success during the implementation of nature-based coastal …

Exploring and enhancing context-dependent beta-lactam antibiotic efficacy
… and persistence, in particular, are often context-dependent phenotypes: environmental factors can influence bacterial physiology and alter antibiotic efficacy. Optimal antibiotic use, as well as strategies to enhance antibiotic efficacy, can therefore be informed by studies of …

Systematic determination of a transcription factor/binding site functional interaction landscape
… The functional library sequences reveal context dependence for each half-site and interaction within and across binding site halves. Finally, using an orthogonal PhoP mutant, I found that although these two proteins interacted with very few overlapping promiscuous sequences, there were …

The role of a circalunar clock in speciation
… in speciation and raises new questions about context dependence in magic traits, trait polygenicity, and complexity.

Decisions Dynamics in ICT systems: the influence of a context-aware and social approach on the multiple criteria decision making processes
… characterised by four main features: dynamism, context-dependence, multiple criteria and social influence. Dynamism expresses the continuous change of the characteristics of both environment and of the decision maker who has to perform the process at each time step. Context-dependence, instead, …

Systems and control theoretic approaches to engineer robust biological systems
… This is mainly because genetic systems are context-dependent: the expression level of a synthetic gene often depends not only on its own regulatory inputs, but also on the expression of other supposedly unconnected genes. This lack of modularity leads to unexpected behaviors when multiple …

Untangling the complexity of nature: Machine-learning for accelerated life-sciences
… of such methods remains limited in the broad context of life-sciences. This work optimizes the utility of ML to accelerate research of fundamental biological problems. First, we propose a paradigm shift from siloed data curation to multi-purpose cohorts at scale, even in the most restrictive …

Hearing the Moment: Measures and Models of the Perceptual Centre
… estimates and showed no evidence of P-centre context dependence. Moreover, the PCR method appears most time efficient for generating accurate P-centre estimates. Additionally, the magnitude of the PCR is shown to vary systematically with the onset complexity of speech sounds, which presumably …

"You" and "I", "now" and "then", and some related thoughts
… is the relationship between information and context-how context interacts with the contents of speech and thought. I pursue three issues within this broad theme. Chapter 1 concerns indexicality. On classical accounts, indexicals like I, you, and now invariably refer to elements of the actual …

Characterising Performative Speech Modes via Analysis by Synthesis

Investigating the effect of phytoplankton on bacterial community composition across different environmental contexts

Risk Metrics and the Five-Level System for the Youth Level of Service/Case Management Inventory (YLS/CMI): A Comparison of Two Samples of Justice-Involved Youth in Canada

Semantic knowledge representation and analysis

Macroscopic insights from mechanistic ecological network models in a data void
… underscoring the contingency and context dependence of nature that scientists and policy makers alike should no longer ignore. This work hopes to contribute to a growing multidisciplinary understanding, appreciation and management of complex systems that is fundamentally …
