Modelling Patient Duration of Stay to Facilitate Resource Management of Geriatric Hospitals

A fundamental aspect of health care management is the effective allocation of resources. This is of particular importance in geriatric hospitals where elderly patients tend to have more complex needs. Hospital managers would benefit immensely if they had advance knowledge of patient duration of stay in hospital. Managers could assess the costs of patient care and make allowances for these in their budget. In this paper, we tackle this important problem via a model which predicts the duration of stay distribution of patients in hospital. The approach uses phase-type distributions conditioned on a Bayesian belief network.

The diverse geographies of rural gentrification in Scotland

Gentrification has for too long been investigated as an urban phenomenon. Only relatively recently has it been viewed as an avenue for fruitful rural research. This paper focuses on the repopulation of rural Scotland. Using survey and interview data it examines evidence of gentrification among in-migration flows and seeks to explore both the social transformation of rural areas and the social displacement of rural residents.

The findings point towards important geographical variations. Not all in-migration represents gentrification, and where it does gives rise to very differing impacts. Clear spatial divisions in the local housing market are identified, and evidence is obtained to support a number of differing theoretical debates. Issues of social displacement and population replacement are explored, with the paper tentatively suggesting an important link between urban and rural gentrification processes. Finally, temporal and geographical phases of gentrification are identified. Collectively these findings have direct relevance to how we define gentrification.
