Medical school accreditation in Australia: Issues involved in assessing major changes and new programs

The Australian Medical Council (AMC) is an independent company for quality assurance and quality improvement in medical education in Australia and New Zealand. Accreditation procedures for the 20 medical schools in these two countries are somewhat different for three different circumstances or stages of school development: existing medical schools, established courses undergoing major changes, and new schools. This paper will outline some issues involved in major changes to existing courses, and new medical school programs. Major changes have included change from a 6 year undergraduate course to a 5 year undergraduate course or 4 year graduate-entry course, introduction of a lateral graduate-entry stream, new domestic site of course delivery, offshore course delivery, joint program between two universities, and major change to curriculum. In the case of a major change assessment, accreditation of the new or revised course may be granted for a period up to two years after the full course has been implemented. In the assessment of proposals for introduction of new medical courses, six issues needing careful consideration have arisen: forward planning, academic staffing, adequate clinical experience, acceptable research program, adequacy of resources, postgraduate training program and employment

Effects of memory load and distraction on performance and event-related slow potentials in a visuospatial working memory task

Brain electrical activity related to working memory was recorded at 15 scalp electrodes during a visuospatial delayed response task. Participants (N = 18) touched the remembered position of a target on a computer screen after either a 1 or 8 sec delay. These memory trials were compared to sensory trials in which the target remained present throughout the delay and response periods. Distracter stimuli identical to the target were briefly presented during the delay on 30% of trials. Responses were less accurate in memory than sensory trials, especially after the long delay. During the delay slow potentials developed that were significantly more negative in memory than sensory trials. The difference between memory and sensory trials was greater at anterior than posterior electrodes. On trials with distracters, the slow potentials generated by memory trials showed further enhancement of negativity whereas there were minimal effects on accuracy of performance. The results provide evidence that engagement of visuospatial working memory generates slow wave negativity with a timing and distribution consistent with frontal activation. Enhanced brain activity associated with working memory is required to maintain performance in the presence of distraction. © 1997 by the Massachusetts Institute of Technolog

The development of passive health surveillance by a sentinel network of family practitioners in South Africa

Objective. For the South African Sentinel Practitioner Research Network (SASPREN), a volunteer network of family practitioners in South Africa, to develop a health surveillance system through the surveillance of important health events.Motivation. The incidence of important preventable diseases and the burden of disease are not reliably known in South Africa, both in the public and private sector. Incidence rates determined at primary care level could help with planning and delivery of appropriate health services and monitoring of the impact of intervention programmes.Methods. Altogether 183 sentinel practitioners were recruited in nine provinces, from 2 478 doctors invited to participate. Of these 120 were active in reporting all their new cases of 13 selected health events to the study centre on mailed postcards. After data-capturing, incidence rates were calculated for defined periods. Feedback was given to the sentinels through a newsletter and personalised reports.Results. A network of sentinel family practitioners has been established in South Africa, and can provide incidence rates for both diseases and interventions through a simple and cheap surveillance system. The calculated rates demonstrated periodic trends for certain events, as well as inter-provincial, -gender and -population group differences.Conclusions. As the validity of the dataset and its generalisation to the whole population is uncertain, its usefulness as point estimates of incidence rates isunknown. This information serves as an important pointer for further research. The trends of these rates may provide a valuable tool for monitoring the impact of public health policies

The Rare Decays \piee, \etaee and \etamumu$ in Chiral Perturbation Theory

We calculate the decay rates for \piee, \etaee and \etamumu in chiral perturbation theory. The linear combination of counterterms necessary to render these amplitudes finite is fixed by the recently measured branching fraction for \etamumu. We find \Br(\piee ) = 7\pm 1\times 10^{-8} and \Br(\etaee )=5\pm 1\times 10^{-9}.Comment: (6 pages, 1 figure available on request, uses harvmac.tex), UCSD/PTH 92-23, CALT-68-180

Lemon sole Microstomus kitt in the northern North Sea: a multidisciplinary approach to the early life-history dynamics

Lemon sole Microstomus kitt is a commercially valuable flatfish species that occurs in shelf waters around the northeast Atlantic. Only the most basic life-history information is available for the North Sea. Spawning is generally assumed to occur between early May and October, with a peak between May and August. Lemon sole larvae have been found in the water column in the northern North Sea in winter during standard surveys. Larvae captured in November/December 2016 and January/February 2017 using the International Council for the Exploration of the Seas standard 2 m Midwater Ring trawls (MIK) were analysed to gain a better understanding of the pelagic early life-history stages of lemon sole, especially in relation to the timing of spawning and the dispersal of overwintering larvae. Larval age was estimated from sagittal otolith primary increment counts. The larvae caught in November/December ranged in nominal age from 4 to 45 days post-hatching which suggests that spawning continues into late October and November. Most, but not all, of the larvae caught in January/February were post metamorphosis, and the difference in age between the two sampling dates was consistent with the elapsed time between samplings. The estimated hatching dates confirm that lemon sole spawning extends into late autumn in the northern North Sea, with overwintering larvae in all developmental stages. Drift modelling of eggs and larvae released at historically documented spawning grounds in the northern North Sea suggests that these grounds are also the source for all of the larvae sampled during the 2016–2017 surveys.publishedVersio
