CONTROL MECHANISMS FOR GENERATORS IN ICON
… by a lack of understanding of their operation. Control structures for generating expressions are usually patterned after the control structures found in conventional language designs. A notation for describing the static aspects of generators is presented in this dissertation. This notation is …

Control mechanisms of mammalian pepsinogen secretion
… of this thesis was to delineate aspects of the control mechanisms of mammalian pepsinogen secretion. In order to accomplish this goal, a comprehensive study was undertaken which would establish an historical perspective of the subject, validate appropriate methodology and then seek to answer …

Translational control mechanisms in the p53 response network
… p53 regulates. To investigate mRNA translational control as an additional dimension of p53-directed gene expression responses, we performed translatome analyses upon its activation either by different agents or cellular contexts. Considered as a proxy for the proteome, the translatome allows us to …

Predictive and reactive control mechanisms involved in object manipulation
… investigate some of the predictive and reactive mechanisms supporting manipulation in the context of object lifting. When lifting an object, weight is estimated based on learned associations between the visual features of objects (e.g. size, material) and their weight. However, occasionally these …

Experimental Investigations into Shark Skin Inspired Active Flow Control Mechanisms
… of the mechanism by which flexible shark scales control flow separation.

Investigating dysregulation in protein quality control mechanisms in senescent cells
… of ageing. Proteostasis involves pathways and mechanisms which protect cellular protein homeostasis, including synthesis, folding, trafficking and degradation of proteins. Proteostasis loss is implicated in both normal ageing and diseases of ageing in humans, although which mechanisms are …

Domain-general control mechanisms underlying stopping of thought and action
… the same? Are there common brain regions and mechanisms, which mediate response inhibition regardless of whether one is stopping an action or a thought? In this thesis, we address these questions, and probe the mechanisms mediating stopping. Response inhibition is thought to be achieved either …

Internal Control Mechanisms and Forced CEO Turnover: An Empirical Investigation
… empirically examines the efficacy of internal control mechanisms by analyzing 94 forced turnovers of chief executive officers (CEOs). It seeks to answer two primary questions: One, do governance-related characteristics influence the promptness with which poorly-performing CEOs are removed from …

Control mechanisms for risk-taking: evidence from the UK financial services industry
… attempts by UK and European regulators to impose controls on the PMSs of a number of regulated employees (material risk takers (MRTs)) in the UK financial services sector, in order to modify risk-taking behaviour. Additionally, the thesis investigates banks’ responses to regulatory pressures; …

Stable and fair congestion control mechanisms for cooperative vehicle safety in vehicular networks
… the scalability problem, several congestion control methods have been proposed and are currently under field study. These mechanisms adapt transmission rate and power, based on network measures such as: Channel Busy Ratio (CBR), packet reception rate and vehicles tracking error. Channel Busy …

Inhibitory control mechanisms and their role in task switching: A multi-methodological approach
Executive control allows us to ignore distraction and switch between tasks in a flexible, yet organized fashion. While a hallmark of controlled behavior, distinctions among executive control processes are not thoroughly agreed upon. The present work explored the organization of two of these …

The cue induced axonal nascent proteome and its translational control mechanisms in neural wiring
… of proteomic changes and their translational control mechanisms remain unknown. The ability to investigate the nascent proteome on subcellular compartments has been hampered by the low sensitivity of existing methodology on quantity-limited samples combined with the difficulty of obtaining …

Functional organisation of behavioural inhibitory control mechanisms in cortico-basal ganglia circuitry: implications for stimulant use disorder.
The neural and psychological mechanisms of inhibitory control processes were investigated, focusing on the cortico-basal ganglia circuits in rats and humans. These included behavioural flexibility, ‘waiting’ and ‘stopping’ impulsivity and involved serial spatial reversal learning task in rodents, …

Genetic and biochemical analysis of the colicin I receptor gene of Escherichia coli: Structural organization and transcriptional control mechanisms
The cir gene, which encodes the colicin I receptor protein, is one of several outer membrane proteins synthesized by Escherichia coli in response to iron limitation. The location, organization, and regulation of cir and its neighboring genes were examined by a molecular genetic approach. Following …

Competition-based CRISPR-dCas9 transcriptional control mechanisms and application of dCas9 biosensors for high-throughput, cell-based protease inhibitor screens
… and implement a new-to-nature transcriptional control mechanism using dCas9. Natural promoters use overlapping binding sites as a mechanism for signal integration, where the binding of one transcription factor can augment the activity of another. Here, I implement this strategy in Escherichia …

The Governance of Long-Term Investing in Knowledge Creation - Novel Control Mechanisms for Reducing Managerial Myopia and Increasing Growth in Organizations
… excessive reliance on the short-term financial control of management that is based on the comparison of actual income relative to annual or shorter-term targets. Previous research on corporate governance and corporate internal controls has identified the balancing controls for reducing …

Improving community walking after stroke; the effect of dual task treadmill training on gait, cognition and brain control mechanisms of dual task walking in chronic stroke survivors
… walkers (p = 0.068). Consequently, a randomized controlled trial was performed in 50 chronic stroke survivors to explore to what extent 10 weeks of treadmill training with concurrent cognitive distraction in comparison to 10 weeks of treadmill training with no distraction would change community …

ACCESS : Access Controls for Cooperatively Enabled Smart Spaces
Traditionally, access control mechanisms have been static in nature, requiring explicit intervention in order to change their behavior. However, since security requirements can be expected to change frequently and rapidly in ubiquitous computing environments, access control mechanisms that can …
