Urban Aboriginal‐Australian and Anglo‐Australian children: in‐group preference,self‐concept,and teachers' academic evaluations

The in‐group preference and self‐concepts of urban Aboriginal‐Australian and Anglo‐Australian children have never been compared, nor their relationships to teachers' evaluations of academic performance. In this study, 60 Aboriginal (primarily local Nyoongah) and 60 Anglo children aged 6–12 years were tested on in‐group preference; children aged 8+ were tested on self‐concept. Also, their teachers evaluated them on their general academic performance. Results indicated that Anglo children showed greater in‐group preference and scored higher on teacher evaluations than Aboriginal children, although there was no difference on self‐concept. No correlation existed between in‐group preference and self‐concept. It was concluded that the problems faced by Aboriginal children are only likely to be alleviated by a great deal of structural change. Copyright © 2000 John Wiley & Sons, Ltd.     

Cesarean childbirth: Psychological implications for mothers and fathers

Home observations, ratings of interaction, and interviews were carried out in families with first-born 5-month-old infants. Comparisons were made between two groups of families differing as to whether the childbirth had been a Cesarean or vaginal delivery. Fathers whose babies had been born by Cesarean delivery reported greater involvement in child care and were rated as more responsive to infant distress. Both mothers and fathers tended to show less animation in interactions with their infants following a Cesarean delivery: mothers engaged less frequently in vigorous physical stimulation and showed less reciprocal positive affect with their infants, and fathers smiled less at their infants.     

Fathering during the infancy period: Implications of the mother's employment role

This study addressed fathers' satisfaction with their wives' employment role and fathers' participation in child care and household tasks in a middle-class sample of families with first-born infants in which the mother was either employed or a homemaker. Observations of mother, father, and infant were carried out in the home on weekday evenings when the infants were 12 months old, and parent interviews were carried out after the completion of the observations. On interview measures, fathers with homemaker wives tended to report greater satisfaction with their wives' employment role than did fathers whose wives were employed. In addition, fathers with employed wives, but not those with homemaker wives, reported that they were participating more in child care and household tasks as a result of their wives' emplovment role. On home observation measures, fathers with employed wives were found to engage in somewhat less Distal Interaction with their infants, but the two groups did not differ with regard to Proximal, Complex Social, or Caregiving Interactions. The results indicate the need to give special consideration to the infancy period when one is examining both paternal endorsement of maternal employment and the father's participation with children in light of the mother's employment role.     

Open‐endedness,Schemas and Ontological Commitment

Second‐order axiomatizations of certain important mathematical theories—such as arithmetic and real analysis—can be shown to be categorical. Categoricity implies semantic completeness, and semantic completeness in turn implies determinacy of truth‐value. Second‐order axiomatizations are thus appealing to realists as they sometimes seem to offer support for the realist thesis that mathematical statements have determinate truth‐values. The status of second‐order logic is a controversial issue, however. Worries about ontological commitment have been influential in the debate. Recently, Vann McGee has argued that one can get some of the technical advantages of second‐order axiomatizations—categoricity, in particular—while walking free of worries about ontological commitment. In so arguing he appeals to the notion of an open‐ended schema—a schema that holds no matter how the language of the relevant theory is extended. Contra McGee, we argue that second‐order quantification and open‐ended schemas are on a par when it comes to ontological commitment.
