BIRDS, BARBOUR, AND BOATS

Abstract. Ian Barbour in the second volume of his Gifford Lectures makes a significant contribution to environmental ethics. Worthy of scrutiny are his views on the relation of technology to the environment, on the distinction between nature and culture, on the problem of hierarchical thinking, and on the notion of sustainability. His integrated approach is a model for how we must relate to nature.     

Family characteristics as mediators of the influence of problem drinking and multiple risk status on child mental health

Structural equation modeling was used to test a theoretical model in which family cohesion and family reframing coping were hypothesized as mediators between family drinking problems, multiple risk factors, negative life events, and child mental health (conduct disorder, depression, anxiety) in two-parent families. Family cohesion mediated the relationships of family drinking problems and negative life events to child conduct disorder and depression. Negative life events mediated the relationships of family drinking problems and family multiple risk to child conduct disorder. Family reframing coping did not function as a mediator nor was it related to child mental health when other factors were considered simultaneously. Results indicate that increasing family cohesion and reducing sources of stress within the family (negative life events) represent promising areas for interventions for children with problem-drinking parents. Work on this study was funded in part by the National Institute for Mental Health Grant 2-P50-MH39246-06 to support a Preventive Intervention Research Center.

Stories we tell each other: A comparison of families' and their therapists' explanations of presenting problems

This study reports the explanations of presenting problems given by 10 mothers of children referred to a department of child and family psychiatry and their therapists. Video-recordings of therapists' pre-session meetings and the initial therapy sessions were searched for explanatory statements. These statements were then coded. It was found that therapists referred to past events, present circumstances, relationships, and possible future events in their explanations of presenting problems significantly more frequently than mothers. It was rare for mothers to speak in terms of past or future events at all. The mothers explained difficulties in terms of character traits significantly more often than did the therapists. The implications of these findings are discussed.Thanks to all of the child and family consultation team at 1 Wolverton Gardens for their participation in this research and particularly to Ruth Kossoff for her great help with organising data collection.     

Dealing with time pressure

A sample of 250 people completed a questionnaire where they rated 30 statements describing their behavior and experiences during a recent time pressure situation. A factor analysis resulted in three factors: Personal Burden, Work Problems and Difficulties, and Challenge Orientation. People high on this last factor liked the excitement of being under pressure, were very absorbed in the task, and showed signs of being effective in dealing with the situation. Such individuals were having what has been identified as a flow experience often observed in sports and the arts. The results of this study suggest that effective coping with time pressure is related to taking a task-oriented attitude, avoiding self-preoccupation, and using time management skills to focus on successful achievement.     

Ecological influences in youth crisis shelters: Effects of social density and length of stay on youth problem behaviors

For 472 consecutive days we monitored the number of youths residing in a crisis shelter for adolescents, the average length of stay for the youths residing in the shelter on each day, and the number of problem behaviors occurring within the shelter on a daily basis. We analyzed these data using a combination of time series and logistic regression techniques to fit a model that would predict the occurrence of a problem behavior on any given day. After controlling for significant time trends in the data, our results indicate that both the number of youths in the shelter and the proportion of youths who have resided in the shelter longer than 14 days are significantly associated with a problem behavior occurring on any given day. The number of youths in the shelter and the probability of a problem behavior occurring correlated significantly. However, as the proportion of youths who resided in the shelter longer than 14 days increased, the probability of a problem behavior occurring decreased.     

Co-morbidity of crying and feeding problems with sleeping problems in infancy: Concurrent and predictive associations

The co-morbidity of crying, feeding and sleeping problems at 5 months of age was investigated in a representative sample of 432 infants in South Germany. A crying, sleeping or feeding problem was reported in 32.7% of these infants by their parents and a further 14.6% had two or more of these problems. Little co-morbidity between crying and feeding problems was found. There were moderate to strong associations between crying and sleeping behaviours. Feeding problems showed little relationship to sleeping behaviour, but feeding type and frequency of feeds were related to night waking. Breastfed infants woke much more often at night. Crying and feeding problems at 5 months were poor predictors of sleeping behaviour at 20 or 56 months of age. Later sleeping behaviour was best predicted by infant sleeping behaviour. At 56 months, maternal distress due to sleeping and co-sleeping practices was predicted by maternal distress due to crying and feeding practices at 5 months of age. The predictions were significant but generally weak to modest in strength. Future studies on the consequences of crying or feeding problems should take into account patterns of co-morbidity. So-called ‘post-colicky’ sleep problems are not due to increased crying per se but rather appear to be the consequence of associated infant sleeping problems and parental caretaking patterns for dealing with night waking in infancy.     

Neuromotor Functioning and Behavior Problems in Children at Risk for Psychopathology

Previous studies have found that early neuromotor deficits may be a precursor of later psychopathology. The present study examined the relationship between neuromotor dysfunction and behavioral deviance in children characterized by a variety of risk factors (parental schizophrenia, parental psychiatric disorder other than schizophrenia, and parental maltreatment). The sample consisted of 108 children (average age 9.75 years) who were assessed twice, approximately 1 year apart. It was found that maltreated children had poorer neuromotor functioning and more behavior problems than children who were not maltreated, regardless of parental psychiatric status. The results also indicated that the relationship between neuromotor functioning and problem behaviors varied as a function of parental psychiatric status. These findings suggest that, although the effects of maltreatment are generalized and pervasive, there are distinctive relationships between neuromotor functioning and behavioral deviance depending on the nature of the risk factors a child has been exposed to.     

The Dutch Identity: A new tool for the study of item response models

The Dutch Identity is a useful way to reexpress the basic equations of item response models that relate the manifest probabilities to the item response functions (IRFs) and the latent trait distribution. The identity may be exploited in several ways. For example: (a) to suggest how item response models behave for large numbers of items—they are approximate submodels of second-order loglinear models for 2 ^J tables; (b) to suggest new ways to assess the dimensionality of the latent trait—principle components analysis of matrices composed of second-order interactions from loglinear models; (c) to give insight into the structure of latent class models; and (d) to illuminate the problem of identifying the IRFs and the latent trait distribution from sample data.This research was supported in part by contract number N00014-87-K-0730 from the Cognitive Science Program of the Office of Naval Research. I realized the usefulness of the identity in Theorem 1 while lecturing in the Netherlands during October, 1986. Because this was in no small part due to the stimulating psychometric atmosphere there, I call the result the Dutch Identity.
