Do episodes of mental health (MH) problems cause future MH problems, and if yes, how strong are these dynamics? We quantify the degree of persistence in MH problems using nationally representative, longitudinal data from Australia and system generali

In attempting to model gross migration flows as distinct from net flows entropy and information theory models supplement those from the demographic tradition. However clear differences exist between these two classes including the type of origin and

Spatial Interaction Modelling
Spatial interaction (SI) is the process whereby entities at different points in physical space make contacts, demand/supply decisions or locational choices. The entities can be individuals or firms and the choices can include housing, jobs, productio

Whereas for commuting travel there is a one-to-one correspondence between commuters and jobs, and for commodity flows a one-to-one correspondence between the size of orders and the shipping cost of the commodities, the situation is much more complex

In spatial interaction modelling, trips between origins and destinations within the same areal zone have a predominant influence on both the value of the gravity parameter and on the associated pattern of flows. Despite this, the relevant highly sens

In this book, the author's strong commitment to the multi-disciplinary field of regional science emerges to provide a unifying framework between spatial modelling traditions from quantitative geography and those from spatial economics, whereby each i

In this paper a random matching model is elaborated to characterize bilateral interregional human face-to-face contacts. The bilateral contacts can be realized only when both parties agree to meet each other. Thus, mutual agreement is the core of our

Most recent attempts to improve the empirical performance of classical trade models by formulation of probabilistic models of the DSPE (Dispersed Spatial Price Equilibrium) type have concentrated on determination of flows of a single commodity. Howev

Interregional and international trade models have conventionally used an abstract exchange mechanism to generate the linkages between exogenous supply and demand functions defined in each region (country). This approach is compared with a procedure w
