Log-linear modelling and spatial analysis

In the past decade the social sciences have seen an upsurge of interest in analysing multidimensional contingency tables using log-linear models. Two broad families of log-linear models may be distinguished: the family of conventional models and the family of unconventional models (that is, quasi-log-linear and hybrid models). In this paper a brief review of such models is presented and some linkage to the class of generalised linear models suggested by Nelder and Wedderburn is provided. The great potential of log-linear models for spatial analysis is illustrated in applying conventional and unconventional models in a migration context to identify intertemporal stability of migration patterns. The problem that the effective units migrating are households rather than individuals is coped with by postulating a compound Poisson sampling scheme.

VISITAS RESTRITAS A CRIANÇAS HOSPITALIZADAS: UMA BARREIRA PARA A INTERAÇÃO MÃE-FILHO

The author presents data concerning mother-child relationship promotion, results of her observations in three pediatric hospitals. Verificating that the visit represents the sole opportunity for not breaking mother-child contact, the author discusses some effects of the restricted visit upon mother-child relationship, pointing out the need of including the mother in the child's care.A autora apresenta resultados de observações realizadas em três hospitais pediátricos, quanto à promoção do relacionamento mãe-filho hospitalizado. Constatando ser a visita a única oportunidade para não ser interrompido o contato da mãe com a criança, discute alguns efeitos da visita restrita sobre o relacionamento mãe-filho. Além disso, aponta a necessidade de incluir a mãe na assistência a essa criança, para o bem--estar de ambos

Housing choice processes : stated versus revealed modelling approaches

This paper briefly outlines some of the essential features of stated and revealed modelling approaches and discusses some recent advances in terms of algebraic vs choice heuristic models. Special attention is given to how these modelling approaches can incorporate a large number of attributes, substitution, context effects and group decision-making processes in housing choice behavior
