Space-time Multi Type Log Gaussian Cox Processes with a View to Modelling Weeds

Log Gaussian Cox processes as introduced in Moller et al. (1998) are extended to space-time models called log Gaussian Cox birth processes. These processes allow modelling of spatial and temporal heterogeneity in time series of increasing point processes consisting of different types of points. The models are shown to be easy to analyse yet flexible enough for a detailed statistical analysis of a particular agricultural experiment concerning the development of two weed species on an organic barley field. Particularly, the aspects of estimation, model validation and intensity surface prediction are discussed.     

Conditional Gaussian mixture modelling for dietary pattern analysis

Summary.  Free-living individuals have multifaceted diets and consume foods in numerous combinations. In epidemiological studies it is desirable to characterize individual diets not only in terms of the quantity of individual dietary components but also in terms of dietary patterns. We describe the conditional Gaussian mixture model for dietary pattern analysis and show how it can be adapted to take account of important characteristics of self-reported dietary data. We illustrate this approach with an analysis of the 2000–2001 National Diet and Nutrition Survey of adults. The results strongly favoured a mixture model solution allowing clusters to vary in shape and size, over the standard approach that has been used previously to find dietary patterns.     

Young Adolescents' Patterns of Involvement with Siblings and Friends

We identified different patterns in young adolescents' experiences with their siblings and their friends and investigated the connections between these relationship patterns and both young adolescents' psychosocial functioning and the characteristics of their family and neighbourhood contexts. Participants were 141 families, including mothers, fathers, young adolescents (M = 11.4 years), and their younger siblings (M = 8.3 years). Cluster analysis revealed three groups of young adolescents: (1) high intimacy and involvement with sibling, high intimacy with friend but low involvement with friends ('Differentiated'); (2) high intimacy and involvement with friend but not sibling ('Incongruent'); and (3) low involvement and intimacy with both sibling and friend ('Congruent'). The Congruent pattern was associated with young adolescents' personal characteristics and their parent-adolescent relationship experiences. In contrast, the Incongruent and Differentiated profiles were linked to contextual factors (i.e., family and neighbourhood resources). Findings suggest that individual differences exist in the associations between young adolescents' relationships with siblings and friends.     

Habitat use and activity patterns of urban-dwelling javelina

In Arizona, conflicts between homeowners and urban-dwelling javelina (Tayassu tajacu) continued to increase. Human-javelina conflicts often occurred when javelina responded to urban attractants and destroyed ornamental landscapes, injured pets, and frightened homeowners. This prompted initiation of a study during 1992–93 to develop recommendations to alleviate these conflicts. We captured, radio-collared, and located eight javelina from six herds to determine home ranges, habitat use, and activity patterns in Prescott, Arizona. Urban-dwelling javelina adjusted their home ranges, habitat use, and activity patterns to best use human-provided urban food, water, and cover resources. The most conspicuous of these adjustments was the increased nocturnal activity of urban-dwelling javelina to avoid human disturbances. Undeveloped land within or adjacent to Prescott provided javelina with daytime bedding areas and nighttime travel corridors. We determined that this issue was more a people problem than it was a javelina problem. Thus, strategies to resolve the conflicts must target homeowners.
