Narratives from the neighbourhood: The discursive construction of integration problems in talkback radio1

This paper examines how speakers deploy narrative devices in talking about Sudanese refugees. Particularly, we show how narrative constructions form an important basis for the advancement of accounts about integration problems into the local polity. We analyse talkback ‘phone‐in’ calls to a local Adelaide radio station that provide callers an opportunity to give accounts of events and social phenomena that concern them in their local settings. Analysis shows that speakers regularly deployed narrative constructions, first‐hand ‘witnessing’ devices that functioned to legitimate accounts as veridical versions of events, and contrast devices to explicate the moral and behavioural aberrance of Sudanese refugees. The analysis illustrates how these discursive devices function rhetorically in interaction, in ways that differentiate Sudanese refugees as problematic. Through this analysis, we contend that narrative devices precipitate and bolster socio‐political policies that have serious, negative consequences for Sudanese refugees.

Practical Maximum Pseudolikelihood for Spatial Point Patterns(with Discussion)

This paper describes a technique for computing approximate maximum pseudolikelihood estimates of the parameters of a spatial point process. The method is an extension of Berman & Turner's (1992) device for maximizing the likelihoods of inhomogeneous spatial Poisson processes. For a very wide class of spatial point process models the likelihood is intractable, while the pseudolikelihood is known explicitly, except for the computation of an integral over the sampling region. Approximation of this integral by a finite sum in a special way yields an approximate pseudolikelihood which is formally equivalent to the (weighted) likelihood of a loglinear model with Poisson responses. This can be maximized using standard statistical software for generalized linear or additive models, provided the conditional intensity of the process takes an 'exponential family' form. Using this approach a wide variety of spatial point process models of Gibbs type can be fitted rapidly, incorporating spatial trends, interaction between points, dependence on spatial covariates, and mark information.
