Upon review of the English literature and the patients at our hospital, we identified 94 renal transplant recipients with nocardiosis. These patients were further evaluated and compared to nonrenal transplant patients with nocardiosis. We found that these patients were similar in presentation, course, and therapeutic outcome to non-transplant patients.(More)
In order to clarify the epidemiology and clinical spectrum of endemic blastomycosis, we reviewed the charts of 326 culture and/or histologically proven cases of blastomycosis in Mississippi from 1979 to 1988. Cases were dispersed throughout the state, but counties in central and south-central Mississippi reported 63% of all blastomycosis cases. The average(More)
We explore various definitions and characteristics of emergence, how we might recognise and measure emergence, and how we might engineer emergent systems. We discuss the TUNA (Theory Underpinning Nanotech Assemblers) project, which is investigating emergent engineering in the context of molecular nanotechnology, and use the TUNA case study to explore an(More)
The ability of Clonorchis sinensis to cause severe hepatobiliary disease is illustrated by the case we have reported, in which biliary obstruction and hepatic fibrosis resulted from the pathologic process associated with chronic clonorchiasis. Immunodiagnostic tests are currently limited, and diagnosis, as illustrated by our case, relies on identification(More)
We consider models of emergence, adding downward causation to conventional models where causation permeates from low-level elements to high-level behaviour. We describe an architecture and prototype simulation medium for tagging and modelling emergent features in CA-like systems. This is part of ongoing work on engineering emergence.

We propose a framework for engineering emergent behaviour that allows system specification and design at the level of the emergence. We discuss how rule migration can be used to translate this high-level multi-layer design (mobile process model) into an equivalent simple cellular automaton model with only local rules, and emergent behaviour. In this paper,(More)
Occupational therapy asserts that leisure, along with self-care and work, is a primary occupation of individuals and essential to occupational functioning. The purpose of this study was to explore the leisure assessment practices of occupational therapists in a variety of settings. A telephone survey, developed by the researchers, was administered to 105(More)
We propose a framework for engineering emergent behaviour that allows system specification and design at the level of the emergence. We discuss how rule migration can be used to translate this high-level multi-layer design (mobile process model) into a simple cellular automaton model with only local rules, from which the behaviour can be described as(More)
This thesis describes a framework for designing emergent behaviour. The framework is comprised of a simulation architecture, a rule migration process, and a rule combination language. Desired emergent behaviour is specified using a multi-level model which describes the behaviour at the appropriate level in the emergence hierarchy, using downward causation(More)
