To analyze the influence of different health status dimensions and quality of life (QoL) domains on older adults' subjective health, and to assess the role that residential satisfaction plays in these relationships. A QoL survey was conducted on a representative sample of the community-dwelling older adult population in Madrid province (Spain). Logistic regression models were applied to studying: the health status dimensions associated with satisfaction with health; the relationship between satisfaction with health and other QoL domains; and, the influence of these domains on satisfaction with life. Sociodemographic and residential characteristics were included in all the models. The determinants of satisfaction with health in the first model were: mobility, usual activities, morbidity, and satisfaction with neighborhood. QoL domains associated with health were: leisure activities, neighborhood, and finances. Satisfaction with life was explained by these three domains, along with age, family and health. In sum, leisure, neighborhood, and finances showed a positive effect on satisfaction with health and with life.

Many facilities have negative impacts on neighbouring areas, and an obvious social and political concern is therefore to assess and minimise such impacts. The authors address this type of problem in relation to the dispersion of aircraft noise near airports. The approach involved brings together two basic components. First, two spatial models are presented. These are developed from existing concepts in location theory and modelling, but the authors attempt to overcome some of the limitations of previous models. Second, a geographical information system is used to obtain a better representation of the spatiotemporal processes involved in the dispersion of aircraft noise and to evaluate the functions of the two models. A case study is used to illustrate the methodology and helps to indicate how this approach could facilitate improved spatial decisionmaking.
