The study examined relations between family human and social capital and the educational attainment and occupational aspirations of 420 Australian 20-yr.-olds. After taking into account the relations between human capital and the outcome scores, the findings indicated that family social capital had significant associations with the young adults' attainment and aspirations.
This study used longitudinal data to investigate associations among sibling-related variables, adolescents' perceptions of family and school learning environments, and social-status attainment measures, for 300 young Australian adults from different social-status groups. The findings indicated that: (a) sibling-related variables continued to have a number of significant associations with young adults' social-status attainment after taking into account mediating relationships between adolescents' learning environments and the attainment measures, and (b) these relationships between sibling and attainment measures varied for young adults from different social-status groups.
The study examined the proposition that relationships among sibling variables, intellectual ability, and academic achievement vary for children from different family-environment groups. Data were collected from 900 11-yr.-old Australian children and their parents. In the analysis, the children were classified into four family contexts that were defined conjointly by family social status and parents' academic socialization. Within each family group, regression surfaces were constructed from models that included terms to account for possible linear, interaction, and curvilinear associations among the variables. The results suggested the general proposition that within the family-environment groups, sibling variables were not related to academic achievement at different levels of children's ability. However, the findings indicated that there were variations to this general proposition. Indeed, there were a number of complex associations between the sibling variables and children's academic achievement in the different family-environment groups.
I used longitudinal data to examine relationships between sibling variables and young adults' status attainment at different levels, based on earlier measures of adolescents' educational and occupational aspirations. My analyses involved 21-year-old Australians from Anglo-Australian, Greek, and Southern Italian families. Regression surfaces were plotted from models that included terms to test for possible linear, interaction, and curvilinear associations among the variables. My study showed that the number of children in a family and birth order continue to be significantly associated with young adults' status attainment, even after incorporating the mediating influences of adolescents' aspirations. The investigation also suggested ethnic group differences among sibling variables, adolescents' aspirations, and young adults' status attainment.
Longitudinal data from 240 female and 260 male Australians were used to examine relationships among birth order, sibsize, and adolescents' perceptions of family learning environments after taking into account the correlation of intellectual ability and social status on those perceptions. For the analysis, regression models were investigated that included terms to test for possible linear, interaction and curvilinear relationships. The findings provided tentative support for the sibling dilution theory, that is, after accounting for the effects of children's ability and family social status, the sibling variables continued to have some modest associations with the adolescents' perceptions of their parents' support for learning.

Regression surface analysis was used to examine relations between various family environment measures and young adults' educational and occupational outcomes. Data were collected from 330 Australians as part of a 10-year longitudinal study. The regression models included terms to account for possible linear, interaction, and curvilinear relationships. In general, the analysis suggests the proposition that parents' aspirations and adolescents' perceptions of parents' support for learning have differential linear and curvilinear associations with the educational and occupational outcomes of young adults from different social-status groups.

The study examined to what extent relationships between sibsize and the cognitive and affective chaarcteristics of children were mediated by family environments. The Alice Heim nonverbal intelligence test (AH4), the Watts Vernon English test, and the Vernon graded mathematics test were used to assess the cognitive performance of 15-year-old children (383 boys and 396 girls). The Ss formed part of a longitudinal national study of English school children. Also schedules were administered to measure children's educational and occupational aspirations, self-concepts, and attitudes toward school. From parental interviews a family environment index consisting of both distal and proximal measures was constructed. The Jackknife technique was used in the analysis to adjust significance levels. Regression surface analysis indicated that at each environment level, sibsize was related only to the English achievement of girls and boys and to the aspirations of girls. However, the shapes of the surfaces suggest that if parents create differential learning environments for different siblings then the behaviors of the siblings are likely to vary, which provides tentative support for the confluence model of sibsize influences on the behaviors of children.

Regression surfaces were plotted from models that included terms to test for possible linear, interaction, and curvilinear associations among the variables. The study indicated that sibsize and birth order continued to have many significant associations with young adults' status attainment even after taking into account the mediating influence of perceived family environments. Also, the investigation suggested that there are ethnic-group differences in relations among sibling variables, perceived parents' support for learning, and young adults' status attainment.
