The relationship of maternal employment to early adolescent daily experience with and without parents.

This study examines how maternal work may shape pre- and young adolescents' daily life experience. According to the procedures of the Experience Sampling Method (ESM), 295 10-13-year-old children carried electronic pagers for 1 week and completed self-report forms in response to random signals sent every other hour. Their daily experience did not differ by maternal employment status, with the following exceptions: full-time maternal employment was associated with more time doing homework with mothers and less time in general leisure, while part-time employment was associated with more time doing sports with parents. Relative to those with nonemployed mothers, youth with part-time employed mothers reported more positive daily moods and higher self-esteem, while youth reported time with full-time employed mothers to be the friendliest. While children with employed mothers spent no less time with family, parents, friends, in class or alone, they spent more time alone with fathers.

"Taking care": Maintaining the self and the home in early adolescence.

This paper explores young adolescents' experience of basic daily tasks: personal maintenance (e.g., grooming and eating) and household maintenance (e.g., chores and errands). Quantity of time, companionship, and subjective states in these activities were examined during one week in the lives of 401 5th-9th graders with the Experience Sampling Method (Csikszentmihalyi and Larson, 1987). Our findings show that these tasks are particularly subject to sex typing. Girls engaged in grooming more often than boys, and this time increased in the higher grades, while boys showed no age effects. Boys did more outside chores while girls did more indoor chores. Girls were also more likely to carry out household tasks with family while boys did more chores alone. An examination of subjective states during household maintenance revealed that older girls reported a greater sense of motivation and choice than younger girls, but boys' experience did not differ. Experience of maintenance as socialization for adult activities is discussed.

"We were just talking ...": Conversations in early adolescence.

This paper explores young adolescents' experience of talk, examining changes in boys' and girls' patterns of communication with family and friends. The data consist of immediate self-reports provided by 401 5th-9th grade students during the course of one week of their normal lives. Results indicate that while time spent talking to friends increased dramatically across this age period, especially for girls, talk with family members remained stable. Analysis of topics of conversation suggests that older children turned to friends for discussions of age-related concerns while continuing to discuss daily issues with family members. Talk with friends did not appear to replace talk with family members but rather represented a new facet of the social world, supplementing existing family relationships.

Physical/chemical and microbiological analyses of dusts at a resource recover plant.

Airborne dusts at a resource recovery pilot plant were sampled and analyzed to determine physical, chemical and microbiological characteristics. The sampling device was a multi-stage impactor equipped with a pre-collector. Dusts are primarily fibrous organic materials, predominantly of nonrespirable size. Microbiological aerosol concentrations are reported and discussed.

Canonical correlation analysis: potential for environmental health planning.

There is a challenging need to identify the relationships between environmental quality and health status. It may be especially important to be able to isolate key variables which can be consolidated into a few indices of environmental conditions as they are related to health. Such indices might be used to identifying associations among groups of variables, such as specific geographic area. The indices may also provide insights into environmental health relationships which are worthy of further epidemiological investigation. Canonical correlation analysis is a multivariate statistical technique which provides a means of identifying associations among groups of variables, such as health and environmental measures. The technique can produce weighted indices of environmental conditions as they are related to health within a city or region. This paper describes what canonical correlation is, and outlines how it might be used for these purposes. An illustrative application based on data collected for Philadelphia, Pennsylvania is also presented.
