The birth, death and catastrophe process is an extension of the birth-death process that incorporates the possibility of reductions in population of arbitrary size. We will consider a general form of this model in which the transition rates are allowed to depend on the current population size in an arbitrary manner. The linear case, where the transition rates are proportional to current population size, has been studied extensively. In particular, extinction probabilities, the expected time to extinction, and the distribution of the population size conditional on nonextinction (the quasi-stationary distribution) have all been evaluated explicitly. However, whilst these characteristics are of interest in the modelling and management of populations, processes with linear rate coefficients represent only a very limited class of models. We address this limitation by allowing for a wider range of catastrophic events. Despite this generalisation, explicit expressions can still be found for the expected extinction times.

There is a long tradition of some general practitioners developing areas of special interest within their mainstream generalist practice. General practice is now becoming increasingly fragmented, with core components being delivered as separate and standalone services (eg, travel medicine, skin cancer, women's health). Although this fragmentation seems to meet a need for some patients and doctors, potential problems need careful consideration and response. These include loss of generalist skills among GPs, fewer practitioners working in less well-remunerated areas, such as nursing home visits, and issues related to standards of care and training.

The wild mungbean, Vigna radiata ssp. sublobata, is an 'old world' tropical species indigenous throughout the better watered areas of northern Australia. Variation among 115 accessions, mainly from Australia, West Timor, and Papua New Guinea, was evaluated for several diverse traits. The plants were cultivated in the field at 2 sowing dates, at both a tropical and a subtropical location, with 6 accessions from India and a mungbean cultivar for comparison. Substantial variation was identified for traits of potential agronomic, adaptive, or taxonomic interest. For some traits, like phenology, the variation appeared to be systematic, with plausible underlying physiological and/or adaptive explanation. Among accessions, wild type traits, like prostrate habit, more gracile morphology, twining form, and small hard seeds, tended to be associated. There was a general geographic trend for lines collected from locations more remote from where mungbean has historically been cultivated to show greater expression of wild type traits, with few 'traits of domestication' evident in the Australian accessions. Some of the identified variation, e. g. higher seed protein content, hardseededness, and putative disease resistance, may be of value in mungbean variety improvement. A more targetted evaluation of the collection would likely reveal other adaptations, especially tolerance to environmental stresses. As such, the wild accessions are a potentially valuable if under-utilised germplasm resource.

We have recently developed a principled approach to interactive non-linear hierarchical visualization [8] based on the Generative Topographic Mapping (GTM). Hierarchical plots are needed when a single visualization plot is not sufficient (e.g. when dealing with large quantities of data). In this paper we extend our system by giving the user a choice of initializing the child plots of the current plot in either interactive, or automatic mode. In the interactive mode the user interactively selects ``regions of interest'' as in [8], whereas in the automatic mode an unsupervised minimum message length (MML)-driven construction of a mixture of GTMs is used. The latter is particularly useful when the plots are covered with dense clusters of highly overlapping data projections, making it difficult to use the interactive mode. Such a situation often arises when visualizing large data sets. We illustrate our approach on a data set of 2300 18-dimensional points and mention extension of our system to accommodate discrete data types.

Influences on general practitioner prescribing of drugs continue to be of interest and importance as cost containment becomes central to Government health policy. This thesis employs a plurality of research methods including quantitative and qualitative survey techniques for example, questionnaires, interviews and prescription analyses to investigate some of the factors which may influence GP prescribing such as information sources, hospital consultants and in particular the community pharmacist. When the use and influence of drug information sources by GPs was examined, the community pharmacist was given a relatively low rating as a source but a high rating, similar to that of the consultant, for helpfulness. Influences are needed to improve prescribing and reduce the incidence of iatrogenic disease for the benefit of the patient. The education and expertise of pharmacists and their familiarity with local prescribing habits places them in a unique position to meet the needs of local GPs. As 96.5% of the public always or nearly always take their prescriptions to the same pharmacy, patient medication records, now kept by 77.5% of pharmacies, provide a valuable check on the appropriateness and safety of patients' medication. The barriers to the pharmacist's greater involvement were shown to be suspicion by GPs of pharmacists' motivation, isolation of many community pharmacists, difficulties in leaving the pharmacy for domiciliary visits, residential home care and GP practice meetings. These barriers must be lowered if the pharmacist is to have a greater influence and involvement. It was concluded that changes are necessary in pharmaceutical education, staff training, organisation and remuneration. Some changes in the targeting of remuneration to the pharmaceutical care services provided and registration of patients with pharmacies would contribute greatly to these aims.
