This study examined associations among early adversity, diurnal cortisol, child sex, and caregiver sensitivity at age 6 months in relation to wheezing in children (47% male) followed to 30 months. Analyses included 676 mother-child dyads, 393 of whom completed an observational caregiver sensitivity measure. Participants were primarily ethnic minorities (42.7% Black, 25.4% Hispanic); 22.1% of children had ≥ 1 wheezing episode. Higher adversity was associated with increased wheeze frequency and blunted diurnal cortisol slope. The indirect effect of adversity on wheezing through cortisol slope was significant for females, but not males. Higher caregiver sensitivity was protective against wheezing for males, but not females, with high cortisol. Findings suggest complex associations among adversity, cortisol, child sex, and caregiver sensitivity in predicting wheezing. 相似文献

Parental involvement and participation, partnership with parents, and community‐focused development are important features of government initiatives such as the Sure Start project for children under four years of age and their families. A common feature of the rhetoric is ‘empowerment’ as a means of achieving this. This article describes the activity and development of the Parents Committee in one Sure Start programme and uses this to tease out different dimensions of empowerment. In particular, it highlights issues regarding developing empowerment and the dynamic tension between the growth of personal power and the changing symmetry of power relationships. A tentative model of the trajectory of developing empowerment is presented. This may raise challenges for professionals seeking to fulfill their professional role in a complex context and questions as to whether, or how, it might be possible to better prepare professionals for this dimension of their work. 相似文献

Students’ educational motivation is significant for performance and achieving learning, but little is known about what fuels such motivation. Educational motivation is regarded as the drive and inner state that energise educational activities, facilitate learning and channel behaviour towards achieving educational goals. Educational motivation paves the way for students to learn and acquire the knowledge that is essential for successful study outcomes. This article aims to explore what determines students’ educational motivation. Building on the self-determination theory, we modelled the influence of teachers’ leadership and students’ self-efficacy on students’ educational motivation. We used survey data from a sample of upper secondary school students in Sweden; we received a total of 993 answers, equal to a response rate of 74%. The results show that students’ self-efficacy and teacher leadership are of extreme importance for students’ educational motivation, and that highly efficacious students lose most educational motivation when the teacher’s leadership is poor. The results thus support the importance of teachers’ leadership for encouraging student learning. 相似文献

Questionnaire data collected from male and female university students 25 years of age or older were used to investigate correlates of their performance, satisfaction, and adjustment in college. Men reported lower levels of performance and satisfaction. Multiple regression analyses of predictors of college grade-point average, satisfaction with college, and affective changes occurring while in college indicated that these three measures were predicted by demographic variables, by aspects of the college experience, by the external out-of-college responsibilities of these students, and by their goals. Each of the three dependent measures was predicted by a different subset of these variables. 相似文献

This paper explores a series of nineteenth century court cases involving the failed delivery of telegraphic ‘death messages.’ In these cases, friends or family members of a deceased or dying person failed to receive a telegram announcing the death or illness, and thus either missed their loved one's funeral or were unable to see them before they died. The intended recipient of the telegram then sued the telegraph company over the emotional suffering they experienced as a result. Those cases that were decided on behalf of the presumably emotionally wronged party offered a complex understanding of the public responsibilities of telecommunications companies. In the view of the courts that made these decisions, these companies were not simply responsible for transmitting messages. They also had an empathetic duty to the feelings of their customers. These court decisions have much to teach media historians about nineteenth century communications law and the emotional implications of new technologies. 相似文献
