Fitting Constrained Poisson Regression Models to Interurban Migration Flows

This paper demonstrates the effects of fitting singly and doubly constrained spatial interaction models using the Poisson regression approach. A large data set containing migration flows between labor market areas in Great Britain in 1970–71 is used. The results of fitting unconstrained, singly constrained, and doubly constrained models are compared with respect to goodness of fit and the interpretability of parameter estimates. The addition of other explanatory variables to the model is also explored.     

Modeling Migration Careers,Using Data from a British Survey

Development of more sophisticated techniques for modeling longitudinal data has implications for improving our understanding of migration. This paper uses longitudinal data from the British Social Change and Economic Life initiative to disentangle the effects of population heterogeneity, progress through the life cycle and secular change on observed migration differentials. The data consist of retrospective life histories from people sampled in several contrasting localities in Great Britain, in which residential moves can be linked to changes in occupation and household structure. We present a framework for analysis of data of this type using a generalized linear modeling approach, together with results concerning variations in the probability of migration with age, gender, and changes in household and occupational circumstances. Of particular note is the evidence of substantial duration-of-residence effects and an unexpected later-career increase in migration propensity.     

A DYNAMIC INTRSECTORAL,MODEL OF REGIONAL ECONOMIC GROWTH*

ABSTRACT. The dynamic relationship between sectoral value added and regional economic growth is analyzed using a stochastic intersectoral model estimated by ordinary least squares and linear systems techniques. A state-space portion of the model identifies the time element of sedoral value added. Dynamic multipliers, tracing the temporal path of regional growth, are calculated for the state of Georgia over the period 1963–1986. This application shows that the impacts of sectoral shocks can follow cyclical as well as monotonic patterns and that the direction and magnitude of the impact may change over time.     

Madness and colonisation: The embodiment of power in Pangia

The article considers two examples of ‘madness’ which occurred during the colonial era in Pangia district, Southern Highlands Province, PNG. The first, immediately prior to pacification, concerned outbreaks of madness among young Wiru men which were similar to the ‘wildman’ behaviour described in the Highlands ethnography. The second style of madness was associated with the so-called ‘hysteria’ accompanying revival activity by Christian missions. The two styles are compared using a Foucauldian perspective, primarily for the ways in which colonial technologies of power were inscribed on the bodies of Pangia people. The article presents an anatomy of colonial power, and suggests an ethnohistory of the body is possible. It examines the ways in which this power was created through discourses and practices involving concepts of the ‘primitive’ and ‘heathen,’ resulting in a transformation of the Wiru subject.
