Glenn I. Roisman Elizabeth Susman Kortnee Barnett-Walker Cathryn Booth-LaForce Margaret Tresch Owen Jay Belsky Robert H. Bradley Renate Houts Laurence Steinberg The NICHD Early Child Care Research Network 《Child development》2009,80(3):907-920
This study examined early observed parenting and child-care experiences in relation to functioning of the hypothalamic-pituitary-adrenocortical axis over the long term. Consistent with the attenuation hypothesis, individuals ( n = 863) who experienced: (a) higher levels of maternal insensitivity and (b) more time in child-care centers in the first 3 years of life had lower awakening cortisol levels at age 15. Associations were small in magnitude. Nonetheless, results were (a) additive in that both higher levels of maternal insensitivity and more experience with center-based care uniquely (but not interactively) predicted lower awakening cortisol, (b) not accounted for by later caregiving experiences measured concurrently with awakening cortisol at age 15 or by early demographic variables, and (c) not moderated by sex or by difficult temperament. 相似文献

Jay Rounds 《Curator: The Museum Journal》2007,50(1):135-146
Abstract Preliminary evidence suggests that as few as 1,000 readers are attentive consumers of the museum studies literature. Does this suffice to ensure that the field is benefiting appropriately from its investment in research and theory development? Four complementary research strategies are proposed for studying the relationships between museum professionals and published research. 相似文献

Jay Alden 《Performance Improvement》2007,46(6):42-48
Human performance technology professionals often seem disdainful of measuring attitudes. Yet we need to measure them to determine such things as user satisfaction and product appeal. A distinction can be made between a quantitative approach to the measurement (questionnaire) and a qualitative approach (opinionnaire). Questionnaires are appropriate for determining trends and making critical organizational decisions, and opinionnaires are appropriate for exploring opportunities for performance improvement. Appearing identical in form, they differ significantly in their development, testing, and application. 相似文献
