Electrical activity can be recorded from three distinct conduction systems-the through-conducting nerve net and two slow systems (SSl and SS2). Spontaneous and evoked pulses are shown in recordings from M etridium senile. The responses and interactions of these systems seem to control important components of actinian behaviour. SSI pulses are seen during the opening of Tealiafe!ina in response ...

Mackie et al. (2003) present an exploratory Monte Carlo meta-regression of selected cohort mortality and exposure data for three dioxin-exposed cohorts [National Institute for Occupational Safety and Health (NIOSH), Ranch Hand, and Seveso] as a critique of our earlier publication of a similar analysis (Kirman et al. 2000). Although we appreciate that our preliminary examinations of the cohort m...

Branching space-times (BST) theory, as developed elsewhere, permits a sound and rigorously definable notion of ‘originating cause’ or causa causans—a type of transition event—of an outcome event. Mackie has famously suggested that causes form a family of ‘inus’ conditions, where an inus condition is ‘an insufficient but non-redundant part of an unnecessary but sufficient condition’. In this ess...

Dr. Alfred T. Lane (Stanford University) organized the sixteenth annual meeting of the Society for Pediatric Dermatology, held in Wiliiamsburg, Virgitiia. The seventh annual Sidney Hurwitz Lecture was delivered by Dr. Rona M. MacKie (University of Glasgow) on "Melanoma: Risk Factors in Dysplastic Nevus Syndrome." President Anne Lucky (Cincinnati, Ohio) welcomed the society members to Wiliiamsbu...

Nominal rewriting is a framework of higher-order rewriting introduced in (Fernández, Gabbay & Mackie, 2004; Fernández & Gabbay, 2007). Recently, (Suzuki et al., 2015) revisited confluence of nominal rewriting in the light of feasibility. We report on an implementation of a confluence tool for (non-closed) nominal rewriting, based on (Suzuki et al., 2015) and succeeding studies.

RonaMcLeodMacKie was born in 1940 in Dundee, Scotland, an only child. Her father, Norman Davidson, was a biochemistry professor at Glasgow University, and so she was familiar with academic life. She went to four schools before the age of 10 due to familymoves, including Aberdeen and London, but finished her education at the Laurel Bank School for Girls in Glasgow (a private school; University o...
